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.


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.


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.
