Abstract

A bearing radial dynamic loading fault simulation diagnosis test bed is provided. A drive motor is mounted at one end of a rack; an output shaft of the drive motor is connected to one end of a main rotating shaft, and the other end of the main rotating shaft is connected with an input shaft of a motor load; a main test bearing is mounted on the main rotating shaft and is fixed on the rack; a radial dynamic loading device comprises a loading claw a telescopic spring sleeve, a linear sliding block, a lifting linear sliding rail and a loading rack; the loading rack is fixed on a bench; the lifting linear sliding rail is fixed on the loading rack; the linear sliding block is slidably mounted, in an up and down manner, in the lifting linear sliding rail; one end of the telescopic spring sleeve is fixedly connected with the linear sliding block, and the other end of the telescopic spring sleeve is fixedly connected with the top surface of the loading claw; the bottom of the loading claw is in an arc shape and is in contact with the main rotating shaft; and the linear sliding block is connected with a loading transmission mechanism which is used to drive the linear sliding block to slide up and down. According to the invention, the radial dynamic loading in any change pattern can be realized, and the lower energy consumption and the lower cost of the implementation are realized.

Description

technical field [0001] The invention relates to a bearing loading test device, in particular to a bearing radial dynamic loading fault simulation diagnosis test bench. Background technique [0002] Rolling bearings are widely used in mechanical systems, and their quality directly affects the performance of mechanical systems. In mechanical equipment, if the bearing is damaged, it will affect the stability and reliability of the equipment operation if it is light, and it will cause serious accidents if it is serious. Failure often results in large economic losses and even casualties. In order to ensure the long-term effective operation of the bearing, the bearing generally needs to undergo a large number of tests and performance evaluations. Therefore, a bearing loading test device is needed to test the bearing performance by simulating the actual operating conditions. Traditional bearing radial loading devices are mostly static loading, and existing dynamic loading technol...
