Abstract

The invention discloses a bearing fault predicating test system, and belongs to the technical field of product structures of devices or systems which are mainly applied to the bearing fault predication test in mechanical device products. The system comprises a main shaft servo motor mounted on a base, a main transmission system and a load loading and testing device; the main shaft servo motor is connected with the main transmission system through a connecting key; the main transmission system and the load loading and testing device are connected through a plum blossom shaped elastic coupling; the main transmission system, the load loading and testing device and the plum blossom shaped elastic coupling are provided with independent lubricating systems. According to the system, a loading sleeve and a loading shaft which have different inside diameter can be replaced to perform fault predication test for bearings with different models or types, in order to overcome the shortages of the existing bearing fault predicating test bench technology; meanwhile, the whole fault occurring process of the bearing can be simulated, and the effect of predicating the service life of the bearing can be achieved.

Description

technical field [0001] The invention relates to a bearing failure prediction test system, which belongs to the technical field of mechanical equipment product structure, specifically belongs to the technical field of equipment or system product structure mainly used in bearing failure prediction test in mechanical equipment products. Background technique [0002] As an important basic component, bearings are widely used in various mechanical equipment, requiring high precision, high reliability and long life. Bearing failure prediction test system is the key equipment for bearing life research. This type of experimental equipment in the prior art can only test one type or type of bearing, and the loading method is mostly horizontal loading. After loading, there is a certain horizontal displacement; There is a certain error in the measured value of the load and the like. Contents of the invention [0003] The invention provides a bearing fault prediction test system aimin...
