Characterized by small volume, high transmission efficiency, large deceleration range and high accuracy, planetary gear motor for robot is a drive equipment that is widely used, especially in transmission systems for robots. Servo motor, steeper motor and DC motor can be incorporated into the using of planetary gear motor. Resulted from the structure of planetary gear motor, the minimum single-stage deceleration of which is 2.8, while 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 less than 3 generally, but some customized gear motors with large deceleration have stage-4 gear ratio.Compared with other gear motor, planetary gear motor have the characteristics of high rigidity, high accuracy, high transmission efficiency, high torque/volume ratio and long-term maintenance.
Planetary gear motor for robot is essential core components and have high requirements for the positioning accuracy and repetitive positioning precision, which is different from other conventional planetary gear motor because normal robots perform repetitive act during working. Gear motor for robot especially light robot with small volume and light weight, is supposed to meet the need of light weight. Gear motor for robot mainly includes planetary gear motor for intelligent robot, harmonic gear reducer and RV gear reducer for 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 structure specification of planetary gear motor is below:
Voltage :3V to 4V.
Transmission noise :lower than 45dB
Deceleration ratio: 5 to 1500.
Output speed:5rpm to 2000rpm
Output torque : 1 gf.cm to 50 kgf.cm
Transmission accuracy:1-2 arc min
Our planetary gear motor can be customized, e.g planetary gear motor for educational robot, service robot, for industrial robot, for medical robot, for research and exploration robot and for robot in outdoor.
