Industrial robots are classified according to their mechanical structure; they can be divided into SCARA robots, Cartesian robots, articulated robots, parallel robots, etc. As an important component of the core components of industrial robots, precision reducers are indispensable for reliable and accurate operation of industrial robots. The main parts of the reducer used in industrial robots are RV reducer and harmonic reducer. How to distinguish the use?

The reducer for 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, improving the rigidity of the mechanical body and outputting a larger torque.

The RV reducer is suitable for heavy-duty robots. Because of its heavy weight and large size, the RV reducer is generally placed in the position of heavy loads such as the machine base, arm, shoulder, etc., that is, it is mainly used for robots over 20 kg. Joints; harmonic reducers are used for small robots or several axes at the end of large robots. They are characterized by small size, light weight, large bearing capacity, high motion accuracy, large single-stage transmission ratio, low noise and high efficiency.

From the above, it can be known 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 the end axes of light and small industrial robots.
