Characterized by small volume, high transmission efficiency, large deceleration range, and high accuracy, planetary gear motor for the robot is a piece of drive equipment that is widely used, especially in transmission systems for robots. Servo motor, stepper motor and DC motor can be incorporated into the use of planetary gear motor. Resulted from the structure of planetary gear motor, the minimum single-stage deceleration is 2.8, the maximum is less than 12.5 in normal, and the common deceleration ratio is 3,4,5,6,8 and 10. The stage of planetary gear motor is generally less than 3, but some customized gear motors with large deceleration have stage-4 gear ratio. Compared with other gear motors, planetary gear motors have the characteristics of high rigidity, high accuracy, high transmission efficiency, high torque/volume ratio, and long-term maintenance.
Planetary gear motor for the robot is one of the essential core components and has high requirements for positioning accuracy and repetitive positioning precision, which is different from other conventional planetary gear motors because normal robots perform repetitive acts during working. Gear motor for robot especially light robot with small volume and light weight, is supposed to meet the need for light weight. Gear motor for robot mainly includes planetary gear motor for the intelligent robot, harmonic gear reducer, and RV gear reducer for the joint robot. Similar to planetary revolving around stars, planetary gear motor has three planetary wheels running around a sun wheel. Widely applied in industry, planetary gear motor with small volume, light weight, high loading capacity, long service life, smooth running, and low noise, is featured by power splitting and multi-tooth meshing and can be used alone.
The technical parameter of ZHAOWEI precision planetary gear motor ranges from 8mm to 38 mm. According to materials, planetary gear motor can be divided into plastic gear motor and metal gear motor.
