High-speed bearing performance testing machine

Abstract

The invention discloses a high-speed bearing performance testing machine, and belongs to the technical field of durability testing devices. The problem that ultra-high-speed durability test conditioncannot be provided due to limited machine test capability, when a common bearing durability testing machine is used in the process of testing a high-speed motor bearing is solved. The high-speed bearing performance testing machine comprises a rack, and further comprises a bearing driving module used for installing a test bearing to be tested and driving the test bearing to rotate; a radial loadingmodule used for exerting radial loading force on the test bearing; an axial loading module used for exerting axial loading force on the test bearing; a detection module used for detecting the temperature and the vibration frequency of the surface of the test bearing; an operation module used for setting loading force and visual output of the detection information. The invention discloses a high-speed bearing performance testing machine which can provide ultra-high-speed durability test conditions and simulate the working environment of various bearings. The high-speed bearing performance testing machine is wide in application range, and meets the production efficiency at the present stage. The structure is simple, and the operation is convenient.

Description

technical field [0001] The invention belongs to the technical field of endurance testing devices, in particular to a bearing high-speed performance testing machine. Background technique [0002] The bearing is the part of the machine that supports the rotating shaft or the linear motion shaft. It plays the role of supporting the rotating body or the linear moving body in the machine. When other parts move relative to each other on the shaft, it is used to maintain the center position of the shaft. and the parts that control the movement. The life of the bearing is defined by the number of revolutions (or the number of hours of work at a certain speed). For bearings within this life, initial fatigue damage (flaking or defect) should occur on any of its bearing rings or rolling elements. [0003] In the prior art, in the process of testing high-speed motor bearings, ordinary bearing durability testing machines cannot provide ultra-high-speed durability test conditions due to ...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, in the process of testing high-speed motor bearings, ordinary bearing durability testing machines cannot provide ultra-high-speed durability test conditions due to the limited testing capacity of the machine, which is difficult to meet the current production and use, and brings great inconvenience to operators. Therefore, there is still room for improvement
