Grease lubrication rolling bearing service life acceleration experiment device based on switched reluctance motor

Abstract

The invention aims at providing a grease lubrication rolling bearing service life acceleration experiment device based on a switched reluctance motor, and the experiment device can control the experiment temperature, thereby obtaining more accurate measurement data. The grease lubrication rolling bearing service life acceleration experiment device comprises a switch reluctance motor, a supportingmodule and a controller used for controlling the switch reluctance motor to work. The supporting module is of a box-type structure with a hollow cavity, a temperature sensor and a limiting part used for limiting a rolling bearing to be detected are arranged in the hollow cavity, a motor shaft of the switched reluctance motor penetrates through the limiting part of the supporting module, and an airinlet and an air outlet are formed in the side wall of the hollow cavity. And a radial loading block is mounted on the motor shaft. The temperature and precision requirements of the grease-lubricatedrolling bearing can be met, the life test period of the grease-lubricated rolling bearing is shortened, the test cost is saved, the test result can meet the actual use condition of the test rolling bearing, and the grease lubrication rolling bearing service life acceleration experiment device has good practicability.

Description

technical field [0001] The invention belongs to the technical field of machinery, and in particular relates to a rolling bearing life acceleration test device. Background technique [0002] Grease-lubricated rolling bearings are one of the essential key basic components in many rotating machines, and the service life of rolling bearings is an extremely important performance index during the use of rolling bearings. Therefore, in order to better understand the performance indicators of rolling bearings, it is necessary to conduct life tests on related rolling bearings to ensure the safety and reliability of rolling bearings in actual use. [0003] At present, due to the different types of rolling bearings, the actual use environment of rolling bearings is also different. The actual use environment of rolling bearings has an important impact on the life of rolling bearings. Therefore, it is very necessary to develop rolling bearing life test benches according to the actual use...

AI Technical Summary

Problems solved by technology

The test of grease lubricated rolling bearings on the current experimental equipment uses permanent magnet motors, brushed DC motors and single-phase asynchronous motors, etc., and these motors have different shortcomings, and the most important problem is the structure of non-switched reluctance motors. Complicated and expensive, the cost will be higher when measuring the same rolling bearing, it does not meet the economic requirements

Moreover, when using other motors to drive, a coupling is used, which will be attached to the vibrating rolling bearing when transmitting power, causing a large error
