Abstract
The invention relates to a radial loading device for a bearing tester. The bearing tester comprises a case which is composed of a case cover and a case base connected up and down. A test spindle is arranged inside the case. The test spindle is fixedly sleeved with a radial loading bearing. The outer ring of the radial loading bearing is fixedly sleeved with a bearing block. The radial loading device comprises an inverted 'V'-shaped bracket. An oil cylinder is fixedly installed on the upper part of the bracket. The plunger of the oil cylinder extends out of a through hole arranged in the bracket, and is then fixedly connected with a sensor mounting plate. The sensor mounting plate is fixedly connected with a load sensor. The load sensor moves up and down with the plunger of the oil cylinder, and applies the radial load output by the oil cylinder to the bearing block. As the radial loading device is separated from a tester cover, test can be debugged without installing the tester cover under the condition of low test speed and temperature. Therefore, the test process is simplified, and the test efficiency is improved.
