The main transmission structure of planetary gear reducer is planetary gear, sun gear and ring gear. The ring gear is in close contact with the internal gear. The sun gear driven by external power is located in the middle part of the ring gear.

Planetary Gear generally installed on the planet carrier, rotates on the support shaft of the planet carrier, and is always in constant mesh with the adjacent sun gear and outer gear ring. Usually, helical gears are used to improve the stability of work. Occasionally it also rotates around the central axis of the sun gear.

The sun gear acts as a driving gear in the planetary reduction mechanism. The power on the input shaft of the gearbox is first transmitted to the sun gear, and then transmitted from the sun gear to the planetary gear, planetary gear carrier, ring gear, etc. Since the sun gear is on the high-speed, lightly…

The Belt Pulley is a low-speed high-torque transmission part. It combines the advantages of belt transmission, chain transmission and gear transmission. When it works, it transmits power through the meshing of the synchronous belt teeth and the pulley groove.

The 1st gear reducer uses gears of different sizes to reduce the number of revolutions of the motor to the required number of revolutions to obtain a larger torque mechanism. The reducer can be widely used in smart home, automobile transmission, consumer electronics, communication equipment, precision instruments, optical equipment, robot transmission and other fields.
