Abstract

The invention discloses a thrust bearing durability test device, and belongs to the technical field of bearing test devices. The device comprises a supporting frame, a sliding column assembly, a pressure applying mechanism, a rotating shaft and a driving mechanism. The sliding column assembly comprises an upper suspension structure connected to the pressure applying mechanism, a sliding column connected to the rotating shaft and a spring arranged on the sliding column in a sleeving mode. A spring tray is arranged on the sliding column; one end of the spring is propped against the upper suspension structure, and the other end of the spring abuts against the spring tray; the thrust bearing is connected between the upper suspension structure and the sliding column; the thrust bearing, the sliding column and the rotating shaft are coaxial; the rotating shaft can be rotatably arranged on the supporting frame; the pressure applying mechanism is configured to apply axial pressure to the thrust bearing in the axial direction of the thrust bearing; and the driving mechanism is configured to drive the rotating shaft to drive the thrust bearing to rotate around the axis of the rotating shaft.Compared with the prior art, the device can make the test state of the thrust bearing to keep consistent with the actual working state, so that the test accuracy of the thrust bearing is improved.

Description

technical field [0001] The invention relates to the technical field of bearing test devices, in particular to a thrust bearing durability test device. Background technique [0002] The struts of the MacPherson suspension of passenger cars require thrust bearings to transmit torque and reduce friction when turning the steering wheel, and thrust bearings are crucial in the strut system. When the vehicle is running, if the thrust bearing is damaged, it is prone to problems such as abnormal noise, so it is necessary to test the thrust bearing. [0003] The current thrust bearing durability test rig is basically a universal test rig. The boundary conditions, fixing methods, and loading methods of the thrust bearing are all simulated by fixtures, which makes the test state of the thrust bearing different from the actual working state. Affects test results for thrust bearings. Contents of the invention [0004] The purpose of the present invention is to provide a thrust bearing...
