Problems solved by technology

However, in China, the research on bearings is still in the initial stage of research and development. Because there is no suitable device for testing the performance of new structural bearings, people's understanding of the load of different bearings is not comprehensive enough.

Abstract

The invention provides a radial loading device for a bearing performance test experimental platform, which mainly arranges a radial loading device on a platform corresponding to a stepped shaft. The radial loading device is mainly provided with a vibration motor and a vibration isolating assembly on the upper and lower sides of a base frame. The base frame includes a base frame top cover and a base frame body. The base frame body and the base frame top cover are opposite to each other and form a complete circle for holding the stepped shaft, the opening of a base frame vertical plate is internally provided with the vibration motor, a pneumatic cylinder is connected below a base frame horizontal plate connected to the vibration motor, the pneumatic cylinder is connected to a base through abottom connection member, and the lower ends of the base bottom plate are arranged in two sliding slots in parallel of a test platform. The invention can convert the exciting force of the vibration motor and the constant force of the pneumatic cylinder into the load force on the stepped shaft of the tested bearing, and can regulate the load force on the stepped shaft by adjusting the vibration frequency, the amplitude and the overall position of the vibration motor, thereby greatly facilitating the experimental research and exploration of bearing support characteristics.

Description

[0001] Field [0002] The invention relates to an experimental device for testing bearing performance. Background technique [0003] With the development of high-precision technology, traditional bearings can no longer meet the production needs. As a result, magnetic bearings and hydrostatic bearings have gradually been recognized and widely used. However, in China, the research on bearings is still in the initial stage of research and development. Because there is no suitable device for testing the performance of new structure bearings, people's understanding of the load of different bearings is not comprehensive enough. Contents of the invention [0004] The object of the present invention is to provide a radial loading device used for a performance testing experiment platform of a magnetic fluid double suspension bearing. On both sides of the magnetic fluid double suspension bearing performance test platform, there are radial magnetic fluid double suspension bearings an...
