Abstract

The invention discloses a Halbach tapered permanent magnetic bearing comprising permanent magnetic rings having triangular cross sections. The Halbach tapered permanent magnetic bearing comprises a rotation shaft and a corresponding stator mounting base, a rotation shaft mounting base having a right triangle-shaped cross section is fixedly installed on the rotation shaft, movable magnetic rings are assembled to an inclined plane of the rotation shaft mounting base by lap piling, and multiple static magnetic rings are assembled to an inner inclined plane of the stator mounting base facing to the movable magnetic rings by lap piling. The invention also discloses a magnetic force determination method of the Halbach tapered permanent magnetic bearing comprising the permanent magnetic rings having the triangular cross sections. The Halbach tapered permanent magnetic bearing and the method have the advantages that a bearing capacity is large, axial and radial magnetic forces exist, and a Halbach tapered permanent magnetic bearing magnetic force analytic model comprising the permanent magnetic rings having the triangular cross sections is constructed so that magnetic force calculated quantity is greatly reduced and design and optimization of the Halbach tapered permanent magnetic bearing are convenient.

Description

technical field [0001] The invention belongs to the technical field of machinery and mechanics, and relates to a Halbach tapered permanent magnetic bearing composed of a triangular cross-section permanent magnetic ring, and also relates to a magnetic force determination method for the Halbach tapered permanent magnetic bearing composed of a triangular cross-sectional permanent magnetic ring. Background technique [0002] In order to realize energy-saving, high-efficiency, high-speed and reliable operation of rotating machinery (such as high-speed machine tools, flywheel energy storage), it is necessary to solve the key technical problem of high-speed rotor support. Traditional mechanical bearings such as rolling bearings and hydrodynamic pressure bearings have contact and need to be lubricated. It is difficult to meet the requirements of high speed, heavy load and low friction loss. It has become the bottleneck of high-speed traditional drives. Permanent magnetic suspension ...
