Compared with ordinary gear transmission, planetary gear transmission has many unique advantages. The most significant feature is that power can be divided when transmitting power, and the input and output shafts are on the same horizontal line. So planetary gear transmission has been widely used in various mechanical transmission systems, including reducers, speed boosters, and transmission devices. Especially due to its characteristics of high load and large transmission ratio, it has been widely used in aircraft and vehicles (especially heavy vehicles). [1] Planetary gears also play a significant role in the torque transmission of the engine. Due to the significant differences in engine speed, torque, and other characteristics from road driving requirements, it is necessary to alloe engine power appropriately to the driving wheels and utilize the aforementioned characteristics of planetary gears for conversion. The automatic transmission in automobiles also utilizes the characteristics of planetary gears to obtain different transmission ratios by changing the relative motion relationships of various components through clutches and brakes.
