The precision planetary reducer is mainly composed of planetary gears, sun gears and outer ring gears. The transmission ratio of planetary reducers generally does not exceed 10 due to the characteristics of the structure.

　　Compared with other types of reducer, the precision planetary reducer has higher rigidity and precision, as well as high transmission efficiency and torque.

　　Due to its own characteristics, the precision planetary reducer is mostly used in the deceleration transmission of stepping motors and servo motors to reduce the speed of the transmission motor and increase the torque.

　　Several key technical indicators of precision planetary reducer for industrial robots:

　　Several key technical indicators for evaluating precision planetary reducers for industrial robots include the following aspects: torsional stiffness, starting torque, transmission accuracy, free travel, backlash, transmission efficiency, and transmission error.

　　Do a good job in the establishment and improvement of the technical indicators of the precision planetary reducer for industrial robots. It is extremely important to improve the development and application of the precision planetary reducer for industrial robots for comprehensive and comprehensive evaluation of the precision planetary reducer for industrial robots Meaning.
