Zhejiang Laifual Drive Co., Ltd., gear suppliers, is a national high-tech enterprise founded in 2013, mainly engaged in research and manufacture of high precision harmonic reducers and planetary gear reducers. The total factory is 30,000 square meters.

Planetary drive gearbox  can be powered by either electric motors, hydraulic motors, or petrol or diesel combustion engines. The load from the sun gear in transmission is distributed to several sun planet gears which can either be used to drive an outer ring or a shaft or spindle. The central sun gear takes a high-speed, low-torque input. It drives several rotating external gears which increases the torque. The simple design is a highly efficient and effective way of transferring power from a motor to an output. Approximately 97% of the energy input is delivered as an output. Those planetary gear drives manufacturer also have industrial planetary gearbox, planetary speed increaser and so on.
