A Vibration and Fatigue Life Testing Device for Robot Reducer

Abstract

The invention discloses a vibration and fatigue life detection device for a reducer for a robot, which includes a test bench, a bracket arranged on the test bench, a rigid-flexible conversion mechanism, a power transmission mechanism that provides power for the tested reducer, and a power transmission mechanism for the tested reducer. The tested reducer provides a load loading mechanism and a detection mechanism for detecting the parameters of the tested reducer. The support hole for the tested reducer is provided on the bracket, and the rigid-flexible conversion mechanism is embedded in the support hole and sleeved in the On the tested reducer, the rigid-flexible conversion mechanism includes the inner ring of the tested reducer, a number of elastic components surrounding the inner ring, and a rigid ring that can be detached and sleeved on the inner ring. Both the outer sides of the elastic component and the rigid ring are against the inner wall of the support hole, and the rigid-flexible conversion mechanism switches between a flexible state and a rigid state. In this case, a set of devices can carry out two performance tests, which can reduce the cost of purchase and maintenance, greatly reduce the occupied space, and achieve the purpose of improving the efficiency of the device.

Description

technical field [0001] The invention relates to the technical field of mechanical detection, in particular to a vibration and fatigue life detection device of a reducer for a robot. Background technique [0002] As the core component of industrial robots, the reducer's transmission accuracy and reliability directly determine the life and use accuracy of industrial robots. All reducers are precision transmission equipment, and there are processing and assembly errors in mass production, and in the actual use process, the vibration of the reducer directly affects the safe operation of power equipment such as drive shafts, engines or motors, and may even cause serious damage. as a result of. Vibration detection and fault analysis of the reducer is one of the key technical means to feed back the manufacturing and assembly errors of the reducer, improve the repeat positioning accuracy and transmission stability of the reducer, and prolong the service life of the robot. Therefor...

Problems solved by technology

[0005] Therefore, due to the different requirements of the above two performances, the existing methods use two detection devices to detect the two performances respectively, and there are problems such as the large space occupied by the two sets of devices, and the large purchase and maintenance costs caused by numerous mechanisms.
