Fault Diagnosis and Life Evaluation Simulation Test Bench for Rolling Mill Bearings

Abstract

The invention provides a rolling mill bearing fault diagnosis and life evaluation simulation test bench, including a motor, a main shaft, a coupling, a hydraulic loading system, a support system, a rolling mill bearing, a rolling mill bearing seat assembly, an acceleration sensor and a base plate, a rolling mill bearing and a rolling mill The bearing seat assembly is installed in the middle of the main shaft. There are support springs and arc-shaped support plates at the bottom of the rolling mill bearing seat assembly to isolate the rolling mill bearings. Both ends of the main shaft are supported by the support system. The hydraulic loading system applies radial loads to the rolling mill bearings. The motor passes through The coupling is connected with the main shaft. The simulation test bench for fault diagnosis and life evaluation of rolling mill bearings of the present invention can simulate the load conditions imposed on the rolling mill bearings during operation of the rolling mill, and can simultaneously perform fault tests of different combinations or life tests of the same working conditions on two rolling mill bearings. . The reliability of the test is guaranteed, and the influence of other components except the rolling mill bearing on the test is reduced, and the stability of the test is improved.

Description

technical field [0001] The invention belongs to the technical field of bearing fault diagnosis and life test, and particularly relates to a rolling mill bearing fault diagnosis and life evaluation test bench. Background technique [0002] Bearings, as the key components that provide support in rotating equipment, have an important impact on the working performance and service life of the equipment. However, under the combined effect of internal factors and external factors, some subtle defects gradually evolve into failures during operation, and the performance will gradually decline until eventually failure. The bearing fault diagnosis and life evaluation test bench is capable of not only failure testing but also life evaluation. Collecting the relevant information of the bearing in normal state or fault state, or the entire life cycle, helps the tester to grasp the fault evolution law and life test information of the bearing during operation, so as to provide help for the...

AI Technical Summary

Problems solved by technology

The existing bearing life test bench cannot simulate the load conditions of the rolling mill during the rolling process, and can only perform fault tests and life tests on a single bearing, which cannot meet the test requirements for fault diagnosis and life evaluation of rolling mill bearings
