The importance of RV reducer in industrial robot transmission system

The advanced level of today's industrial robots is amazing, especially those 5-axis and 6-axis robots, which not only have numerous joints, but also can achieve precise transmission of motion and instructions, which makes people wonder what their transmission system is.

Globally, precision reducers used in industrial robots can be divided into RV reducers, harmonic reducers and SPINEA reducers. Among them, RV reducer and harmonic reducer are the most mainstream precision reducers for industrial robots.

In articulated robots, the RV reducer is generally placed on the base, arm, shoulder and other heavy loads, and the harmonic reducer is generally placed on the forearm, wrist or hand. RV reducer is the abbreviation of rotary vector reducer. It was first invented by Japan. It is a new hybrid of traditional cycloid pin wheel and planetary gear transmission. The transmission of RV reducer is relatively large.

The core difficulty in the manufacture of RV reducer lies in the close coordination of various processes, such as tooth surface heat treatment, machining accuracy, part symmetry, group technology, assembly accuracy, etc. The results of the total distribution of these process assembly tolerances and product Wear and life are closely related.
