The importance of RV Reducer Gear for industrial robots
The power source of an industrial robot is generally an AC servo motor. Because it is driven by a pulse signal, the servo motor itself can achieve speed regulation.
Why do industrial robots also need a speed reducer?
Industrial robots usually perform repetitive actions to complete the same process; in order to ensure that industrial robots can reliably perform process tasks in production and ensure process quality, the positioning accuracy and repeat positioning accuracy of industrial robots are very high. Therefore, to improve and ensure the accuracy of industrial robots requires the use of RV reducers or harmonic reducers.
Another role of precision reducers in industrial robots is to deliver more torque. When the load is large, it is not cost - effective to increase the power of the servo motor. The output torque can be increased by the reducer in a suitable speed range. In addition, servo motors are prone to heat and low - frequency vibrations at low frequencies, which is not conducive to ensuring accurate and reliable operation for long - term and periodic industrial robots.
The presence of a precision reducer allows the servo motor to operate at a suitable speed and accurately reduce the speed to the speed required by various parts of the industrial robot, increasing the rigidity of the machine while outputting greater torque. Compared with universal reducers, industrial robot joint reducers require short drive chains, small size, high power, light weight and easy control.
