Coaxiality error compensation and experimental verification of RV reducer test system based on laser displacement sensor

Due to the confidentiality of RV reducer's performance indicators and other issues, it is difficult to obtain its technical data and bring some difficulties to its theoretical calculation. At the same time, the performance indicators calculated theoretically are often limited by various factors and can only be used as reference values. Transmission efficiency is one of the most important performance indicators of RV reducer. Therefore, this paper takes the transmission efficiency of RV reducer as an example, aiming at the problem that the coaxiality error of the traditional RV reducer testing system is lack of compensation and adjustment, based on the error compensation principle, a coaxiality error compensation mechanism is proposed to adjust the coaxiality error of the RV reducer to reach the allowable range. Finally, the prototype experiment shows that this mechanism can realize the coaxiality error compensation, and the average transmission efficiency in the steady state is 31.98%, which verifies the accuracy of the compensation mechanism. This research has certain theoretical significance and practical value for improving the performance detection accuracy of RV reducer.
