Planetary Gearheads

Planetary gearheads, generally refer to a planetary gearbox. They normally consist of three parts: sun gear, planet gears, and ring gear. The sun gear is generally placed in the center, while planet gears orbit around the sun gear and receive torque from it. As for the ring gear, the outer ring gear (refers to the housing) meshes with planet gears. ZHAOWEI offers customers 2-stage, 3-stage, and 4-stage planetary gearheads, whose gear ratio ranges from 5-1500.

Advantages of Planetary Gearheads
1. There are metal planetary gearheads and plastic planetary gearheads for you to choose from. You can select based on the technical requirements and actual operating situation, like torque, speed, humid environment, etc.
2. Miniature yet high torque. With more teeth in contact, the mechanism can transmit and withstand more torque in a more uniform manner.
3. Compact size. Due to the planetary structure that multiple gears are meshed together and orbit around a sun gear, the planetary gear motor can be compact and small. 3.4mm, 4mm planetary gear motor, and 6mm planetary gear motor is available.
4. Low noise. The multiple gears enable more surface contact. Rolling is much softer and jumps are virtually nonexistent.
