Problems solved by technology

[0003] In the existing RV reducer test device, when detecting the torque and bending moment of the output shaft, the load position and load size of the load device connected to the output shaft are fixed, and the position and load size of the load device cannot be changed dynamically. The adjustment is separated from the real working condition of the output shaft of the reducer, and the test results are inaccurate

Abstract

The invention discloses a comprehensive testing device for an RV speed reducer, and relates to the field of precision equipment detection. The testing device comprises a slewing mechanism, an X moving mechanism, a Z moving mechanism, an information collecting card, a rack used for installing the slewing mechanism, a computer terminal, a display terminal, a torque sensor and a circular grating, and the computer terminal processes angular displacement signals and torque signals, obtains torque and bending moment parameters of an output shaft of the speed reducer and displays the torque and bending moment parameters on the display terminal. The testing device is mainly used for testing the precision characteristic of the high-precision speed reducer. Omnibearing simulation of the stress state of the output shaft of the speed reducer is achieved, the real working condition of the output shaft is simulated, and the reliability of the test result is high.

Description

technical field [0001] The invention relates to the field of precision equipment testing, in particular to a comprehensive testing device for an RV reducer. Background technique [0002] RV reducers are mostly used in industrial robots, precision machine tools, medical equipment and other fields, and belong to precision instruments and equipment. Usually, after the RV reducer is manufactured, it needs to pass a series of rigorous tests before it can be put into the market after passing the test. [0003] In the existing RV reducer test device, when detecting the torque and bending moment of the output shaft, the load position and load size of the load device connected to the output shaft are fixed, and the position and load size of the load device cannot be changed dynamically. The adjustment is separated from the real working condition of the output shaft of the reducer, and the test results are inaccurate. Contents of the invention [0004] The present invention aims t...
