Abstract

The invention relates to an automobile hub bearing tester. The automobile hub bearing tester comprises a machine body, a main shaft device, an axial loading device and radial loading devices, wherein a main shaft of the main shaft device is horizontally arranged, the two ends in the axial direction are both rigidly connected with test shaft devices, the rotating center line of the main shaft of the main shaft device and the rotating center lines of the test shaft devices coincide, the two test shaft devices are each provided with one radial loading device and a loading body connected with an outer ring of a hub bearing, the loading bodies are provided with loading arms stretching away from the test shaft devices in the radial direction, the center lines of the radial loading devices are perpendicular to the center lines of the test shaft devices, the loading ends of the radial loading devices are connected with the loading bodies, the axial loading device is parallel to the main shaft of the main shaft device and is located between the two radial loading devices, and the two loading ends of the axial loading device are correspondingly connected to the loading arms of the loading bodies. By means of the structure, the automobile hub bearing tester has the advantages that structural design is reasonable, the stress state and size of the hub bearing can be simulated realistically, and detection is accurate and reliable.

Description

technical field [0001] The invention relates to the technical field of bearing test and detection equipment, in particular to a test machine for testing automobile hub bearings. Background technique [0002] Automobile hub bearings are the most important transmission components in automobiles. With the development of the automobile industry, the structure of automotive hub bearings has been improving. The connected flange is designed as an integrated structure, which is called the automobile hub bearing, and the automotive hub bearing plays a very important role in the operation of the vehicle. [0003] The existing test equipment for automobile wheel bearings has unreasonable structural design and inaccurate loading simulation, resulting in inaccurate test results. Contents of the invention [0004] Purpose of the present invention: In order to overcome the defects of the prior art, the present invention provides an automobile hub bearing testing machine with reasonable ...
