Abstract

The invention discloses an accelerated rolling bearing fatigue life tester, which comprises a test head part (2), of which the inside is provided with a test bearing (1), a transmission gear (3), a loading mechanism (4) and a control system, wherein the transmission gear (3), the loading mechanism (4) and the control system are arranged outside the test head part (2); and the loading mechanism (4) is connected with the test head part (2) through a hydraulic piping to load the test bearing. The tester is characterized in that: the transmission gear is a reversible hydraulic motor; the transmission gear (3) is connected with the test bearing (1) to drive the test bearing to rotate reciprocally; and the outside of the test head part (2) is provided with a torque sensor (5) for monitoring the torque of the test bearing, and the control system receives information of the torque sensor and controls the loading mechanism (4) and the transmission gear (3) to stop according to the information. The tester has high testing accuracy and more reliable life testing result.

Description

technical field [0001] The invention relates to the technical field of fatigue life testing of bearings, in particular to a rolling bearing fatigue life strengthening testing machine. Background technique [0002] Rolling bearings are widely used mechanical basic parts, and their quality directly affects the performance of the main engine, and the bearing life is a comprehensive reflection of the bearing quality. The so-called life of the bearing refers to the total number of revolutions before fatigue spalling of any rolling element or raceway in the bearing, or the number of working hours at a certain speed. It can be seen that the reliability of the test results depends to a large extent on the accuracy of the judgment of the contact fatigue failure of the rolling bearing. Therefore, it is of great economic value to accurately test the life test of rolling bearings and accurately predict when fatigue failure occurs. [0003] According to the existing theory of bearing l...
