Problems solved by technology

[0002] Rolling bearing is an important part of contemporary pressure equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. However, it will inevitably wear out or even break during its use. The use of rolling bearings Extensive, among which the rolling bearing detection on the aero-engine rotor is very rigorous, the traditional rolling bearing detection process is through the observation method, and the rolling bearing is observed with the naked eye. There should be no spots, cracks and peeling on the surface of the rolling element. The cage should not be loose, damaged, or worn out. The gap between the rolling element and the rolling element should not be too large. The longitudinal shaking test method shows that the gap between the inner and outer races of a normal bearing and the rolling element is 0.005 ~0.010mm, for rolling bearings that have been used for a period of time, when pinching the inner race with your fingers for axial shaking, use a sound detector to detect the sound waves emitted during the shaking. Rotation method, use one hand to clamp the inner seat of the bearing Turn the outer ring with the other hand, the bearing should be able to rotate flexibly, and should not feel radial shaking, and each step needs to be operated manually, which is labor-intensive and prone to errors, resulting in There are deviations in the detection. Therefore, we propose a longitudinal and radial shake detection device for aero-engine rotor rolling bearings in order to solve the above-mentioned problems

Abstract

The invention relates to the technical field of bearing detection, and particularly relates to an aero-engine rotor rolling bearing longitudinal and radial shake detection device, which comprises a processing table. The device also comprises a longitudinal shake detection mechanism and a radial shake detection mechanism. A controller is arranged between the longitudinal shake detection mechanism and the radial shake detection mechanism. The longitudinal shake detection mechanism comprises a shake seal box, a horizontal material moving assembly, a bottom positioning assembly, a top positioningassembly and two vertical supports. One end of the shake seal box is provided with a folding door. The radial shake detection mechanism comprises a hollow U-shaped base, a material moving assembly, aright positioning assembly, a left positioning assembly, an analog rotation assembly, a lifting assembly and a radial detection assembly. The device only needs to place a detected product in the device and can realize longitudinal and radial automatic accurate detection, thereby reducing detection errors and improving detection efficiency.
