description

Planetary gears refer to a gear system that can rotate around its own axis of rotation like a fixed axis gear, and whose axis of rotation also rotates with the planet carrier around the axis of other gears. The rotation around its own axis is called “rotation”, and the rotation around the axis of other gears is called “revolution”, just like the planets in the solar system, hence the name.
Compared with ordinary gear transmission, planetary gear transmission has many unique advantages. The most notable feature is that power can be split when transmitting power, and the input shaft and output shaft are on the same horizontal line. Therefore, planetary gear transmission has been widely used in reducers, speed increase and speed change devices in various mechanical transmission systems. In particular, it has been widely used in aircraft and vehicles (especially heavy vehicles) because of its “high load and large transmission ratio” characteristics. Planetary gears also play a great role in the torque transmission of the engine. Since the characteristics of the engine’s speed and torque are quite different from the demands of road driving, the above-mentioned characteristics of planetary gears can be used to convert the power of the engine to the drive wheels. Automatic transmissions in automobiles also use these characteristics of planetary gears to obtain different transmission ratios by changing the relative motion relationship of various components through clutches and brakes.
However, due to the complex structure and working conditions of planetary gears, the problems of vibration and noise are also prominent. It is extremely prone to failure phenomena such as gear tooth fatigue pitting, tooth root cracks and even gear teeth or shaft fracture, which affects the operation accuracy of the equipment. Transmission efficiency and service life.
