* Lower cost:

Generally, plastic gears are less expensive to produce than metal gears. As there is usually no need for secondary finishing, plastic gears typically represent a 50% to 90% saving relative to stamped or machined metal gears, according to Plastics Technology.

 

 

* Design freedom:

Moulding plastic offers more efficient gear geometries than metal. Moulding is ideal for creating shapes, such
as internal gears, cluster gears, and worm gears, where the cost for forming them in metal can be prohibitive.

* Reduced noise:

The superior noise-dampening properties of plastics result in a quiet running gear. This has made plastics essential for the high-precision tooth shapes and lubricious or flexible materials required in the ongoing quest for quieter drives.

 

 

 

* Lubrication:

The inherent lubricity of many plastics makes them ideal for computer printers, toys, and other low-load situations that require dry gears. Plastics can also be lubricated by grease or oil.

* Corrosion-resistant:

Unlike metal gears, plastic gears are immune to corrosion. Their relative inertness means they can be used
in water meters, chemical plant controls and other situations that would cause metal gears to corrode or degrade.

* Good shock absorption:

Plastic gears are more forgiving than metal because plastic can deflect to absorb impact loads. It also does a better job of distributing localised loads caused by misalignment and tooth errors.

How to Design a Forging Spur Gear

Before you start designing your own spur gear, you need to understand its main components. Among them are Forging, Keyway, Spline, Set screw and other types. Understanding the differences between these types of spur gears is essential for making an informed decision. To learn more, keep reading. Also, don’t hesitate to contact me for assistance! Listed below are some helpful tips and tricks to design a spur gear. Hopefully, they will help you design the spur gear of your dreams.

Forging spur gears

Forging spur gears is one of the most important processes of automotive transmission components. The manufacturing process is complex and involves several steps, such as blank spheroidizing, hot forging, annealing, phosphating, and saponification. The material used for spur gears is typically 20CrMnTi. The process is completed by applying a continuous through extrusion forming method with dies designed for the sizing band length L and Splitting angle thickness T.
The process of forging spur gears can also use polyacetal (POM), a strong plastic commonly used for the manufacture of gears. This material is easy to mold and shape, and after hardening, it is extremely stiff and abrasion resistant. A number of metals and alloys are used for spur gears, including forged steel, stainless steel, and aluminum. Listed below are the different types of materials used in gear manufacturing and their advantages and disadvantages.
A spur gear’s tooth size is measured in modules, or m. Each number represents the number of teeth in the gear. As the number of teeth increases, so does its size. In general, the higher the number of teeth, the larger the module is. A high module gear has a large pressure angle. It’s also important to remember that spur gears must have the same module as the gears they are used to drive.

Set screw spur gears

A modern industry cannot function without set screw spur gears. These gears are highly efficient and are widely used in a variety of applications. Their design involves the calculation of speed and torque, which are both critical factors. The MEP model, for instance, considers the changing rigidity of a tooth pair along its path. The results are used to determine the type of spur gear required. Listed below are some tips for choosing a spur gear:
Type A. This type of gear does not have a hub. The gear itself is flat with a small hole in the middle. Set screw gears are most commonly used for lightweight applications without loads. The metal thickness can range from 0.25 mm to 3 mm. Set screw gears are also used for large machines that need to be strong and durable. This article provides an introduction to the different types of spur gears and how they differ from one another.
Pin Hub. Pin hub spur gears use a set screw to secure the pin. These gears are often connected to a shaft by dowel, spring, or roll pins. The pin is drilled to the precise diameter to fit inside the gear, so that it does not come loose. Pin hub spur gears have high tolerances, as the hole is not large enough to completely grip the shaft. This type of gear is generally the most expensive of the three.
Gear

Keyway spur gears

In today’s modern industry, spur gear transmissions are widely used to transfer power. These types of transmissions provide excellent efficiency but can be susceptible to power losses. These losses must be estimated during the design process. A key component of this analysis is the calculation of the contact area (2b) of the gear pair. However, this value is not necessarily applicable to every spur gear. Here are some examples of how to calculate this area. (See Figure 2)
Spur gears are characterized by having teeth parallel to the shafts and axis, and a pitch line velocity of up to 25 m/s is considered high. In addition, they are more efficient than helical gears of the same size. Unlike helical gears, spur gears are generally considered positive gears. They are often used for applications in which noise control is not an issue. The symmetry of the spur gear makes them especially suitable for applications where a constant speed is required.
Besides using a helical spur gear for the transmission, the gear can also have a standard tooth shape. Unlike helical gears, spur gears with an involute tooth form have thick roots, which prevents wear from the teeth. These gears are easily made with conventional production tools. The involute shape is an ideal choice for small-scale production and is one of the most popular types of spur gears.

Spline spur gears

When considering the types of spur gears that are used, it’s important to note the differences between the two. A spur gear, also called an involute gear, generates torque and regulates speed. It’s most common in car engines, but is also used in everyday appliances. However, one of the most significant drawbacks of spur gears is their noise. Because spur gears mesh only one tooth at a time, they create a high amount of stress and noise, making them unsuitable for everyday use.
The contact stress distribution chart represents the flank area of each gear tooth and the distance in both the axial and profile direction. A high contact area is located toward the center of the gear, which is caused by the micro-geometry of the gear. A positive l value indicates that there is no misalignment of the spline teeth on the interface with the helix hand. The opposite is true for negative l values.
Using an upper bound technique, Abdul and Dean studied the forging of spur gear forms. They assumed that the tooth profile would be a straight line. They also examined the non-dimensional forging pressure of a spline. Spline spur gears are commonly used in motors, gearboxes, and drills. The strength of spur gears and splines is primarily dependent on their radii and tooth diameter.
SUS303 and SUS304 stainless steel spur gears

Stainless steel spur gears are manufactured using different techniques, which depend on the material and the application. The most common process used in manufacturing them is cutting. Other processes involve rolling, casting, and forging. In addition, plastic spur gears are produced by injection molding, depending on the quantity of production required. SUS303 and SUS304 stainless steel spur gears can be made using a variety of materials, including structural carbon steel S45C, gray cast iron FC200, nonferrous metal C3604, engineering plastic MC901, and stainless steel.
The differences between 304 and 303 stainless steel spur gears lie in their composition. The two types of stainless steel share a common design, but have varying chemical compositions. China and Japan use the letters SUS304 and SUS303, which refer to their varying degrees of composition. As with most types of stainless steel, the two different grades are made to be used in industrial applications, such as planetary gears and spur gears.
Gear

Stainless steel spur gears

There are several things to look for in a stainless steel spur gear, including the diametral pitch, the number of teeth per unit diameter, and the angular velocity of the teeth. All of these aspects are critical to the performance of a spur gear, and the proper dimensional measurements are essential to the design and functionality of a spur gear. Those in the industry should be familiar with the terms used to describe spur gear parts, both to ensure clarity in production and in purchase orders.
A spur gear is a type of precision cylindrical gear with parallel teeth arranged in a rim. It is used in various applications, such as outboard motors, winches, construction equipment, lawn and garden equipment, turbine drives, pumps, centrifuges, and a variety of other machines. A spur gear is typically made from stainless steel and has a high level of durability. It is the most commonly used type of gear.
Stainless steel spur gears can come in many different shapes and sizes. Stainless steel spur gears are generally made of SUS304 or SUS303 stainless steel, which are used for their higher machinability. These gears are then heat-treated with nitriding or tooth surface induction. Unlike conventional gears, which need tooth grinding after heat-treating, stainless steel spur gears have a low wear rate and high machinability.

The Difference Between Planetary Gears and Spur Gears

A spur gear is a type of mechanical drive that turns an external shaft. The angular velocity is proportional to the rpm and can be easily calculated from the gear ratio. However, to properly calculate angular velocity, it is necessary to know the number of teeth. Fortunately, there are several different types of spur gears. Here’s an overview of their main features. This article also discusses planetary gears, which are smaller, more robust, and more power-dense.
Planetary gears are a type of spur gear

One of the most significant differences between planetary gears and spurgears is the way that the two share the load. Planetary gears are much more efficient than spurgears, enabling high torque transfer in a small space. This is because planetary gears have multiple teeth instead of just one. They are also suitable for intermittent and constant operation. This article will cover some of the main benefits of planetary gears and their differences from spurgears.
While spur gears are more simple than planetary gears, they do have some key differences. In addition to being more basic, they do not require any special cuts or angles. Moreover, the tooth shape of spur gears is much more complex than those of planetary gears. The design determines where the teeth make contact and how much power is available. However, a planetary gear system will be more efficient if the teeth are lubricated internally.
In a planetary gear, there are three shafts: a sun gear, a planet carrier, and an external ring gear. A planetary gear is designed to allow the motion of one shaft to be arrested, while the other two work simultaneously. In addition to two-shaft operation, planetary gears can also be used in three-shaft operations, which are called temporary three-shaft operations. Temporary three-shaft operations are possible through frictional coupling.
Among the many benefits of planetary gears is their adaptability. As the load is shared between several planet gears, it is easier to switch gear ratios, so you do not need to purchase a new gearbox for every new application. Another major benefit of planetary gears is that they are highly resistant to high shock loads and demanding conditions. This means that they are used in many industries.
Gear

They are more robust

An epicyclic gear train is a type of transmission that uses concentric axes for input and output. This type of transmission is often used in vehicles with automatic transmissions, such as a Lamborghini Gallardo. It is also used in hybrid cars. These types of transmissions are also more robust than conventional planetary gears. However, they require more assembly time than a conventional parallel shaft gear.
An epicyclic gearing system has three basic components: an input, an output, and a carrier. The number of teeth in each gear determines the ratio of input rotation to output rotation. In some cases, an epicyclic gear system can be made with two planets. A third planet, known as the carrier, meshes with the second planet and the sun gear to provide reversibility. A ring gear is made of several components, and a planetary gear may contain many gears.
An epicyclic gear train can be built so that the planet gear rolls inside the pitch circle of an outer fixed gear ring, or “annular gear.” In such a case, the curve of the planet’s pitch circle is called a hypocycloid. When epicycle gear trains are used in combination with a sun gear, the planetary gear train is made up of both types. The sun gear is usually fixed, while the ring gear is driven.
Planetary gearing, also known as epicyclic gear, is more durable than other types of transmissions. Because planets are evenly distributed around the sun, they have an even distribution of gears. Because they are more robust, they can handle higher torques, reductions, and overhung loads. They are also more energy-dense and robust. In addition, planetary gearing is often able to be converted to various ratios.
Gear

They are more power dense

The planet gear and ring gear of a compound planetary transmission are epicyclic stages. One part of the planet gear meshes with the sun gear, while the other part of the gear drives the ring gear. Coast tooth flanks are used only when the gear drive works in reversed load direction. Asymmetry factor optimization equalizes the contact stress safety factors of a planetary gear. The permissible contact stress, sHPd, and the maximum operating contact stress (sHPc) are equalized by asymmetry factor optimization.
In addition, epicyclic gears are generally smaller and require fewer space than helical ones. They are commonly used as differential gears in speed frames and in looms, where they act as a Roper positive let off. They differ in the amount of overdrive and undergearing ratio they possess. The overdrive ratio varies from fifteen percent to forty percent. In contrast, the undergearing ratio ranges from 0.87:1 to 69%.
The TV7-117S turboprop engine gearbox is the first known application of epicyclic gears with asymmetric teeth. This gearbox was developed by the CZPT Corporation for the Ilyushin Il-114 turboprop plane. The TV7-117S’s gearbox arrangement consists of a first planetary-differential stage with three planet gears and a second solar-type coaxial stage with five planet gears. This arrangement gives epicyclic gears the highest power density.
Planetary gearing is more robust and power-dense than other types of gearing. They can withstand higher torques, reductions, and overhung loads. Their unique self-aligning properties also make them highly versatile in rugged applications. It is also more compact and lightweight. In addition to this, epicyclic gears are easier to manufacture than planetary gears. And as a bonus, they are much less expensive.

They are smaller

Epicyclic gears are small mechanical devices that have a central “sun” gear and one or more outer intermediate gears. These gears are held in a carrier or ring gear and have multiple mesh considerations. The system can be sized and speeded by dividing the required ratio by the number of teeth per gear. This process is known as gearing and is used in many types of gearing systems.
Planetary gears are also known as epicyclic gearing. They have input and output shafts that are coaxially arranged. Each planet contains a gear wheel that meshes with the sun gear. These gears are small and easy to manufacture. Another advantage of epicyclic gears is their robust design. They are easily converted into different ratios. They are also highly efficient. In addition, planetary gear trains can be designed to operate in multiple directions.
Another advantage of epicyclic gearing is their reduced size. They are often used for small-scale applications. The lower cost is associated with the reduced manufacturing time. Epicyclic gears should not be made on N/C milling machines. The epicyclic carrier should be cast and tooled on a single-purpose machine, which has several cutters cutting through material. The epicyclic carrier is smaller than the epicyclic gear.
Epicyclic gearing systems consist of three basic components: an input, an output, and a stationary component. The number of teeth in each gear determines the ratio of input rotation to output rotation. Typically, these gear sets are made of three separate pieces: the input gear, the output gear, and the stationary component. Depending on the size of the input and output gear, the ratio between the two components is greater than half.
Gear

They have higher gear ratios

The differences between epicyclic gears and regular, non-epicyclic gears are significant for many different applications. In particular, epicyclic gears have higher gear ratios. The reason behind this is that epicyclic gears require multiple mesh considerations. The epicyclic gears are designed to calculate the number of load application cycles per unit time. The sun gear, for example, is +1300 RPM. The planet gear, on the other hand, is +1700 RPM. The ring gear is also +1400 RPM, as determined by the number of teeth in each gear.
Torque is the twisting force of a gear, and the bigger the gear, the higher the torque. However, since the torque is also proportional to the size of the gear, bigger radii result in lower torque. In addition, smaller radii do not move cars faster, so the higher gear ratios do not move at highway speeds. The tradeoff between speed and torque is the gear ratio.
Planetary gears use multiple mechanisms to increase the gear ratio. Those using epicyclic gears have multiple gear sets, including a sun, a ring, and two planets. Moreover, the planetary gears are based on helical, bevel, and spur gears. In general, the higher gear ratios of epicyclic gears are superior to those of planetary gears.
Another example of planetary gears is the compound planet. This gear design has two different-sized gears on either end of a common casting. The large end engages the sun while the smaller end engages the annulus. The compound planets are sometimes necessary to achieve smaller steps in gear ratio. As with any gear, the correct alignment of planet pins is essential for proper operation. If the planets are not aligned properly, it may result in rough running or premature breakdown.

Synthesis of Epicyclic Gear Trains for Automotive Automatic Transmissions

In this article, we will discuss the synthesis of epicyclic gear trains for automotive automatic transmissions, their applications, and cost. After you have finished reading, you may want to do some research on the technology yourself. Here are some links to further reading on this topic. They also include an application in hybrid vehicle transmissions. Let’s look at the basic concepts of epicyclic gear trains. They are highly efficient and are a promising alternative to conventional gearing systems.

Synthesis of epicyclic gear trains for automotive automatic transmissions

The main purpose of automotive automatic transmissions is to maintain engine-drive wheel balance. The kinematic structure of epicyclic gear trains (EGTs) is derived from graph representations of these gear trains. The synthesis process is based on an algorithm that generates admissible epicyclic gear trains with up to ten links. This algorithm enables designers to design auto gear trains that have higher performance and better engine-drive wheel balance.
In this paper, we present a MATLAB optimization technique for determining the gear ratios of epicyclic transmission mechanisms. We also enumerate the number of teeth for all gears. Then, we estimate the overall velocity ratios of the obtained EGTs. Then, we analyze the feasibility of the proposed epicyclic gear trains for automotive automatic transmissions by comparing their structural characteristics.
A six-link epicyclic gear train is depicted in the following functional diagram. Each link is represented by a double-bicolor graph. The numbers on the graph represent the corresponding links. Each link has multiple joints. This makes it possible for a user to generate different configurations for each EGT. The numbers on the different graphs have different meanings, and the same applies to the double-bicolor figure.
In the next chapter of this article, we discuss the synthesis of epicyclic gear trains for automotive automatic transaxles. SAE International is an international organization of engineers and technical experts with core competencies in aerospace and automotive. Its charitable arm, the SAE Foundation, supports many programs and initiatives. These include the Collegiate Design Series and A World In Motion(r) and the SAE Foundation’s A World in Motion(r) award.
Gear

Applications

The epicyclic gear system is a type of planetary gear train. It can achieve a great speed reduction in a small space. In cars, epicyclic gear trains are often used for the automatic transmission. These gear trains are also useful in hoists and pulley blocks. They have many applications in both mechanical and electrical engineering. They can be used for high-speed transmission and require less space than other types of gear trains.
The advantages of an epicyclic gear train include its compact structure, low weight, and high power density. However, they are not without disadvantages. Gear losses in epicyclic gear trains are a result of friction between gear tooth surfaces, churning of lubricating oil, and the friction between shaft support bearings and sprockets. This loss of power is called latent power, and previous research has demonstrated that this loss is tremendous.
The epicyclic gear train is commonly used for high-speed transmissions, but it also has a small footprint and is suitable for a variety of applications. It is used as differential gears in speed frames, to drive bobbins, and for the Roper positive let-off in looms. In addition, it is easy to fabricate, making it an excellent choice for a variety of industrial settings.
Another example of an epicyclic gear train is the planetary gear train. It consists of two gears with a ring in the middle and the sun gear in the outer ring. Each gear is mounted so that its center rotates around the ring of the other gear. The planet gear and sun gear are designed so that their pitch circles do not slip and are in sync. The planet gear has a point on the pitch circle that traces the epicycloid curve.
This gear system also offers a lower MTTR than other types of planetary gears. The main disadvantage of these gear sets is the large number of bearings they need to run. Moreover, planetary gears are more maintenance-intensive than parallel shaft gears. This makes them more difficult to monitor and repair. The MTTR is also lower compared to parallel shaft gears. They can also be a little off on their axis, causing them to misalign or lose their efficiency.
Another example of an epicyclic gear train is the differential gear box of an automobile. These gears are used in wrist watches, lathe machines, and automotives to transmit power. In addition, they are used in many other applications, including in aircrafts. They are quiet and durable, making them an excellent choice for many applications. They are used in transmission, textile machines, and even aerospace. A pitch point is the path between two teeth in a gear set. The axial pitch of one gear can be increased by increasing its base circle.
An epicyclic gear is also known as an involute gear. The number of teeth in each gear determines its rate of rotation. A 24-tooth sun gear produces an N-tooth planet gear with a ratio of 3/2. A 24-tooth sun gear equals a -3/2 planet gear ratio. Consequently, the epicyclic gear system provides high torque for driving wheels. However, this gear train is not widely used in vehicles.
Gear

Cost

The cost of epicyclic gearing is lower when they are tooled rather than manufactured on a normal N/C milling machine. The epicyclic carriers should be manufactured in a casting and tooled using a single-purpose machine that has multiple cutters to cut the material simultaneously. This approach is widely used for industrial applications and is particularly useful in the automotive sector. The benefits of a well-made epicyclic gear transmission are numerous.
An example of this is the planetary arrangement where the planets orbit the sun while rotating on its shaft. The resulting speed of each gear depends on the number of teeth and the speed of the carrier. Epicyclic gears can be tricky to calculate relative speeds, as they must figure out the relative speed of the sun and the planet. The fixed sun is not at zero RPM at mesh, so the relative speed must be calculated.
In order to determine the mesh power transmission, epicyclic gears must be designed to be able to “float.” If the tangential load is too low, there will be less load sharing. An epicyclic gear must be able to allow “float.” It should also allow for some tangential load and pitch-line velocities. The higher these factors, the more efficient the gear set will be.
An epicyclic gear train consists of two or more spur gears placed circumferentially. These gears are arranged so that the planet gear rolls inside the pitch circle of the fixed outer gear ring. This curve is called a hypocycloid. An epicyclic gear train with a planet engaging a sun gear is called a planetary gear train. The sun gear is fixed, while the planet gear is driven.
An epicyclic gear train contains several meshes. Each gear has a different number of meshes, which translates into RPM. The epicyclic gear can increase the load application frequency by translating input torque into the meshes. The epicyclic gear train consists of 3 gears, the sun, planet, and ring. The sun gear is the center gear, while the planets orbit the sun. The ring gear has several teeth, which increases the gear speed.
Another type of epicyclic gear is the planetary gearbox. This gear box has multiple toothed wheels rotating around a central shaft. Its low-profile design makes it a popular choice for space-constrained applications. This gearbox type is used in automatic transmissions. In addition, it is used for many industrial uses involving electric gear motors. The type of gearbox you use will depend on the speed and torque of the input and output shafts.
