Problems solved by technology

Complex and alternating stress conditions can easily lead to fatigue damage of bearings
At present, most wheel hub bearing durability testing machines drive the bearings to rotate through the synchronous belt of the motor, and at the same time carry out axial and radial loading through the hydraulic cylinder to simulate the working conditions of the bearings and evaluate the durability of the wheel hub bearings. In the actual use process, the working conditions are quite different, and there are problems of two-way loading force interference and dynamic adjustment force overshoot, which have yet to be resolved

Abstract

The invention relates to an endurance testing machine for wheel bearings, and provides a testing machine capable of testing the endurance of a wheel bearing by simulating the real entrucking conditions of the wheel bearing. The endurance testing machine comprises a working platform, and a driving system and a hydraulic loading system installed on the working platform, wherein the driving system comprises a motor, a main shaft driven by the motor, a main shaft flange fixed on the end portion of the main shaft and a bi-flange connection disc connected with the main shaft flange, and the hydraulic loading system comprises an L-shaped loading device, an axial loading mechanism, a radial loading mechanism and a loading device position adjusting mechanism. The L-shaped loading device comprises two parallel L-shaped loading plates, of which the upper ends are connected with a tool rack with a test piece connecting flange, and lower ends are connected with a bi-lug loading base. The bi-lug loading base is connected with the axial loading mechanism and the radial loading mechanism, and the axial loading mechanism and the radial loading mechanism are installed on the loading device position adjusting mechanism.

Description

technical field [0001] The invention relates to a bearing testing machine, in particular to a testing machine used for testing the durability of automobile hub bearings. Background technique [0002] Hub bearing is one of the key parts of the car. Its main function is to carry weight and provide precise guidance for the rotation of the hub. It can not only bear axial load but also radial load. Complex and alternating force conditions can easily lead to fatigue damage of bearings. At present, most wheel hub bearing durability testing machines drive the bearings to rotate through the synchronous belt of the motor, and at the same time carry out axial and radial loading through the hydraulic cylinder to simulate the working conditions of the bearings and evaluate the durability of the wheel hub bearings. In the actual use process, the working conditions are quite different, and there are problems of two-way loading force interference and dynamic adjustment force overshoot, whi...
