Abstract

The invention relates to a test device for accuracy retention and fatigue life of an RV reducer. The device includes a workbench, a mounting bracket base, an upper pressing plate of the mounting bracket, a servo motor, a mounting plate, an RV reducer to be tested, a temperature sensor, a protruding Arm, simulated swing arm, 2 counterweights namely first and second counterweights, first displacement sensor, sensor bracket, sensor protection frame, detection rod and second displacement sensor. The unit utilizes a counterweight at the end of a simulated swing arm to simultaneously apply variable load torque and load bending moment to the RV reducer. The first displacement sensor is placed under the counterweight to detect the positioning accuracy and repeat positioning accuracy of the RV reducer. The second displacement sensor is placed under the detection rod to detect the bending stiffness of the RV reducer. After a specified time of operation, test the accuracy retention, fatigue life and wear pattern of the RV reducer. The invention provides an experimental basis for theoretical research on the wear rule and accelerated life of the RV reducer.

Description

technical field [0001] The invention relates to a device and method for detecting the positioning accuracy, bending stiffness and fatigue life of an RV reducer, which is characterized in that the accuracy retention and bending stiffness of the RV reducer are detected simultaneously, and belongs to the field of industrial robots. Background technique [0002] RV reducers are key functional components of industrial robot joints. Due to the large gap between domestic RV reducers and foreign products in terms of accuracy retention, rigidity and fatigue life, domestic RV reducers have long relied on foreign imports. The development of RV reducer accuracy retention and fatigue life test device is the basis for theoretical research on fatigue life. Therefore, the development of this test device is of great significance for improving the accuracy retention, rigidity and fatigue life of domestic RV reducer. [0003] During the operation of industrial robots, the RV reducer bears both...
