[0002] Planetary reducer is a kind of reduction transmission device with wide application. It is mainly composed of sun gear, planetary gear, inner ring gear and planet carrier. Its working principle is that the power is transmitted from the input shaft to the sun gear, and the sun gear drives the planetary gear to revolve around the sun gear while rotating at the same time. The planetary gear then drives the inner ring gear meshing with it to rotate, and finally the power is output from the planet carrier to achieve the deceleration effect. Planetary reducer has many advantages, such as: high transmission efficiency, strong load-bearing capacity, small size, light weight, low noise, high precision, smooth operation, etc. It is widely used in various industrial fields, such as lifting and transportation, engineering machinery, metallurgy, mining, petrochemical, construction machinery, light industry and textile, medical equipment, etc., and is an indispensable and important component in modern industrial equipment.
