The reducer for industrial robots is required to have the characteristics of short transmission chain, small size, high power, light weight and easy control. The precision reducer makes the robot servo motor run at a suitable speed, and accurately reduces the speed to the speed required by each part of the industrial robot, and improves the rigidity of the mechanical body while outputting greater torque; the reducer used in the industrial robot Mainly have RV reducer and harmonic reducer. How to distinguish between use?

Industrial robots are classified according to mechanical structure. Can be divided into SCARA robot, Cartesian coordinate robot, joint robot, parallel robot, etc. As an important component of the core components of industrial robots, precision reducer is an indispensable part of reliable and accurate operation of industrial robots. Reducers used in industrial robots mainly include RV reducer and harmonic reducer. How to distinguish between use?

The reducer for robot is required to have the characteristics of short transmission chain, small size, high power, light weight and easy control. The precision reducer makes the robot servo motor run at a suitable speed, and accurately reduces the speed to the speed required by each part of the industrial robot, and improves the rigidity of the mechanical body while outputting greater torque. RV reducer is suitable for heavy-duty robots. Because of its heavy weight and large size, RV reducer is generally placed in the position of heavy load such as base, big arm, shoulder, etc., that is, it is mainly used for robot joints over 20kg. Harmonic reducer is used for small robots or several axes at the end of large robots. It is characterized by small volume, light weight, large carrying capacity, high motion accuracy, large single-stage transmission ratio and low noise, high efficiency.


Through the above, we can know that the RV reducer is mainly used for heavy-duty robots, focusing on the first few joints, and the harmonic reducer is mainly used for several axes at the end of light and small industrial robots.
