Abstract
The invention discloses a radial-axial permanent magnetic bearing system device. The radial-axial permanent magnetic bearing system device comprises a right bearing seat, a right end cover, a right cooling sleeve, a right top seat, a right auxiliary angle contact ball bearing, an axial static magnetic ring, an axial static magnetic ring seat, a radial upper static semi-magnetic ring, a sealing ring, a left bearing radial upper static semi-magnetic ring seat, a left end cover, a left top seat, a permanent magnet bearing inner ring moving magnetic ring seat, a left auxiliary angle contact ball bearing, a moving magnetic ring, a left cooling sleeve, a radial lower static semi-magnetic ring, a sealing ring, a left bearing radial lower static semi-magnetic ring seat and the like. The device further comprises an auxiliary mechanical control protection system composed of a series of parts such as an auxiliary bearing except a combination device composed of the radial permanent magnet bearingand the axial permanent magnet bearing, the device can overcome the defect that a traditional permanent magnet bearing is single in structure and cannot bear the radial-axial composite load in actualapplication, and the application range of the permanent magnet bearing is expanded. The device has the advantages of being compact in structure, high in rotating speed, long in service life and the like, not only has good radial bearing capacity, but also has good axial bearing capacity.
Description
technical field [0001] The invention belongs to the technical field of magnetic suspension bearings, and in particular relates to a radial and axial permanent magnetic bearing system device. Background technique [0002] The relative moving parts (inner and outer rings, inner and outer rings and rolling elements) of the existing types of sliding bearings and rolling bearings are in direct contact with each other, which have relatively large frictional resistance and are prone to heat generation. However, the axial or radial permanent magnetic bearings with a single structure have overcome the shortcomings of the above traditional mechanical bearings, but they cannot meet the needs of bearing the actual middle-diameter and axial compound loads, because for a single The structure of the radial permanent magnetic bearing is stable in the radial direction between the two magnetic rings, and the small displacement in the radial direction can automatically return to a stable posit...
