Problems solved by technology

[0002] At present, the fault simulation test device for rolling bearings is mainly designed for vibration tests. To obtain oil information, you must open the bearing seat after stopping the machine. The obtained oil information has a relative lag. Liquid monitoring and vibration monitoring are two important methods, and the asynchronous information acquisition affects the accuracy of condition monitoring and fault diagnosis analysis

Abstract

The invention discloses a synthesized bearing fault simulation test bed. An experimental bearing pedestal adopts a convenient detachable structure, an unattached lubricating system, and unattached axial and radial loading equipment so that an experimental bearing can be conveniently dismantled and installed, the individual loading of the axial loading and the radial loading of the experimental bearing can be realized, and the united loading of the axial loading and the radial loading also can be realized; a vibration pickup arranged on the experimental bearing pedestal and an oil pipe sampling valve arranged on a lubricating system can realize real-time vibration monitoring and on-line oil detection on a rolling bearing.

Description

technical field [0001] The invention relates to a simulation experiment device, in particular to a comprehensive bearing failure simulation test bench. Background technique [0002] At present, the fault simulation test device for rolling bearings is mainly designed for vibration tests. To obtain oil information, you must open the bearing seat after stopping the machine. The obtained oil information has a relative lag. Liquid monitoring and vibration monitoring are two important methods, but the asynchronous information acquisition affects the accuracy of condition monitoring and fault diagnosis analysis. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a comprehensive bearing failure simulation test bench, which can realize the independent axial and radial loading of the test bearing, and can also realize the combined loading of the two, and can simultaneously obtain the vibration monitoring information of the ro...
