Abstract

The invention discloses an axial and radial combined loading bearing test device. The axial and radial combined loading bearing test device comprises a motor, a motor stand, a main shaft, a supporting bearing, a bearing seat of the supporting bearing, a testing bearing, a loading bearing used for loading axial and radial force, a spring device used for loading radial force, and a spring device used for loading axial force. The loading bearing is arranged on the outer side of the testing bearing and the outer side of the supporting bearing, the bottom of a bearing sleeve of the loading bearing is connected with the spring device used for loading the radial force, and the spring device used for loading the radial force is arranged in the vertical direction. Axial loading rods are arranged on two sides of the middle of a bearing sleeve of the testing bearing and used for being connected with one end of a loading rope. The loading rope is wound around two fixed pulleys, and the other end of the loading rope is connected with the spring device used for loading the axial force. The axial and radial combined loading bearing test device is simple in structure, convenient to dismantle and install and easy to process and manufacture.

Description

technical field

[0001] The invention relates to an axial and radial compound loaded bearing test device. Background technique

[0002] In the actual transmission system, rolling ball bearings often operate under a certain load, which is mainly manifested in two aspects: axial load and radial load. In order to deeply study its operation process and performance under loads in different directions, it is very important to develop a test device that can apply axial load and radial load to the test bearing at the same time for the accurate and smooth development of the test test.

[0003] Existing testing devices for rolling ball bearings often use elastic or rigid loading to carry out single axial or radial loading on the test bearing, and it is difficult to obtain the operating data of the test bearing under the combined action of axial load and radial load. The existing axial loading methods of rolling ball bearings often adopt methods such as pneumatic loading, spring leaf l...
