Temperature-rise test device and method for sealed double-row angular contact ball bearings

Abstract

The invention belongs to the technical field of bearing test equipment, and relates to a temperature-rise test device and method for sealed double-row angular contact ball bearings. A main body of the temperature-rise test device structurally comprises a driving motor, a driving belt wheel, a small belt wheel, a rotation speed sensor, a driving shaft, a control system, a main shaft, a sleeve, an iron sheet, a test bearing, a stress and measurement device, a locking nut, a withdrawal nut, an adapter sleeve, a body, a driving belt, a shell and a stud. The temperature-rise test method comprises the following four steps of: setting test parameters, and starting the test device; determining bearing temperature and environment temperature at initial rotation speed; measuring the bearing temperature and the environment temperature at rated rotation speed; and disassembling the bearing, and performing statistical computation on the measured temperature. The device and the method are applicable to a temperature-rise test on double-row angular contact ball bearings. A test result can be reproduced, and the consistency of test data is high; and the device is simple in structure, principle is reliable, test cost is low, the test result is accurate, test condition is easily controllable, and environmental friendliness can be achieved.

Description

Technical field:

[0001] The invention belongs to the technical field of bearing test equipment, and relates to a temperature rise test device and method for sealed double-row angular contact ball bearings, which are used for temperature rise tests of sealed double-row angular contact ball bearings, and can realize test data consistency and repeatability and reliability. Background technique:

[0002] Double-row angular contact ball bearings can withstand large radial and axial combined loads and moment loads, limit the axial displacement of the shaft in both directions, and are mainly used in components that limit the bidirectional axial displacement of the shaft and the housing; Compared with ball bearings, double row angular contact ball bearings have better rigidity and can withstand overturning moments. The bearings are non-separable and are suitable for applications with high rigidity requirements. They are often used in machine tools, machinery, automobiles and other f...
