Product Description


The role of RV Reducer for robots: industrial robots usually perform repetitive actions to complete the same process; in order to ensure that industrial robots can reliably complete the process tasks and ensure the quality of the process, the positioning accuracy and repetitive positioning accuracy of industrial robots are highly required. Therefore, to improve and ensure the accuracy of industrial robots, it is necessary to use RV or harmonic reducer. Another function of precision reducer in industrial robots is to transmit greater torque. When the load is large, it is not cost-effective to improve the power of servo motor blindly, and the output torque can be increased through the reducer in the appropriate speed range. In addition, servo motors are prone to heat and low-frequency vibration under low-frequency operation, which is not conducive to ensuring the accurate and reliable operation of industrial robots with long time and periodic operation.

The existence of precision reducer makes the servo motor run at a suitable speed, and precisely reduces the speed to the required speed of each part of the industrial robot, so as to improve the rigidity of the mechanical body and output greater torque. Compared with the general reducer, the joint reducer of robot requires the characteristics of short transmission chain, small size, high power, light weight and easy control. Compared with harmonic reducer, RV reducer has higher stiffness and rotation accuracy. Therefore, in joint robots, RV reducer is generally placed in the seat, arm, shoulder and other heavy loads; while harmonic reducer is placed in the arm, wrist or hand; planetary reducer is generally used in rectangular coordinate robots. At the same time, the RV reducer has much higher fatigue strength, stiffness and life than the harmonic drive commonly used in robots, and its backlash accuracy is stable. Unlike the harmonic drive, the motion accuracy will be significantly reduced with the increase of service time. Therefore, the RV reducer is widely used in the high-precision robot drive in many countries.

Above is the role of RV Reducer Used by robots. How much can we know? RV Reducer can improve the repetition accuracy of robots, effectively coordinate the speed of robotic components, while ensuring the normal production of robots, improve the quality of work of robots. RV Reducer is an indispensable and important part of industrial robots.
