Problems solved by technology

[0003] With the high-speed operation of the automobile drive shaft, the automobile hub bearing also needs to meet the relevant requirements, such as the need to bear the axial load, radial load, and high ambient temperature and temperature change during operation; therefore, before the automobile hub bearing is used, Automobile hub bearings need to be tested to see if they can meet the requirements; currently there are related automotive hub bearing testing machines, which can basically meet the relevant test requirements, but the loading is unstable during the test process, the loading accuracy is low, and the loading cylinder There has been no good solution to problems such as large vibration, which has a great impact on the accuracy of test data
This is not compatible with the rapid development of the automobile industry, and it also restricts the further improvement and perfection of the structure of the automobile hub bearing

Abstract

The invention belongs to the technical field of bearing test detection, and provides a loading device for an automobile hub bearing periodicity dynamic tester. The loading device comprises an axial loading mechanism and a radial loading mechanism. Hub bearings (10) are arranged at the cantilever ends at the two ends of a tester spindle (6), outer rings of the hub bearings (10) are fixedly connected with automobile steering knuckles (44), and the automobile steering knuckles (44) are connected with loading arms of the loading mechanisms; the two loading arms are symmetrically arranged at the two ends of the test spindle and correspond to the hub bearings respectively. According to the loading device, loading accuracy can be guaranteed, and stability of the whole device in the operating process is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of bearing testing and detection, and mainly relates to a loading device of a periodic dynamic testing machine for 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 the automobile wheel hub bearing has been improving, from the earliest simple bearing structure to a structure that integrates the flange design of the bearing, the bearing sleeve and the automobile wheel hub; the automobile wheel hub bearing is used in the automobile plays a very important role in its operation. [0003] With the high-speed operation of the automobile drive shaft, the automobile hub bearing also needs to meet the relevant requirements, such as the need to bear the axial load, radial load during operation, and the high ambient temperature and temperature change; therefo...
