Overview of Planetary Reducers and Description of the Gears

- Aug 23, 2019-

In the engineering world, it is customary to refer to the planetary gear transmission and the planetary differential transmission of the gear train, collectively referred to as planetary gear transmission, ie planetary reducer. Therefore, some discussions are still based on planetary gear transmissions.

 

Planetary differential transmission is a special application form of 2K-H planetary gear transmission. It uses different combinations of three degrees of freedom of the 2K-H planetary gear train to achieve operational or power decomposition, control or adjustment. In fact, the planetary differential transmission technology has been used for the motion decomposition on the vehicle, the tilting of the converter and the control transmission of the stretching and bending straightening machine, etc., for many years. In recent years, many new products have been developed using planetary differential transmission technology and play an important role in many industries. Therefore, it is necessary to give a special introduction to the planetary differential transmission technology, which has been widely used in the mechanical engineering industry, resulting in huge economic and social benefits.

In the engineering world, it is customary to refer to the planetary gear transmission and the planetary differential transmission of the gear train, collectively referred to as planetary gear transmission, ie planetary reducer. Therefore, some discussions are still based on planetary gear transmissions.

A series of gears, called gear mechanisms or gear trains, is one of the most widely used forms of mechanical transmission. According to whether the relative position of the geometric axes of each wheel is changed according to the rotation of the wheel train, the wheel train can be divided into the following two basic types:

(1) Fixed axle train When the gear train is running, if the geometrical axis position of all the gears of the planetary reducer that make up the train is fixed, it is called fixed axle train or ordinary train.

(2) Epicyclic gear train When the train wheel is in motion, if the geometric axis of at least one of the gears constituting the train wheel is not fixed and rotates around the geometrical axis of the other gear, it is called an epicyclic gear train.
