Abstract

The invention discloses a zero-friction superconducting magnetic suspension bearing device. The superconducting suspension principle and the existing self-stabilization function of superconducting suspension are utilized, rotors can automatically restore to initial positions once the rotors deviate, non-contact position sensors are not needed to detect the displacements of the rotors, so that thesize of a magnetic suspension bearing is greatly reduced, the manufacturing cost is reduced, and the reliability is improved; and the design is simple, initial suspension positions an starting force are provided for the rotors by adopting a self-developed starting suspension brake, when the whole system is in a vacuum environment, starting and braking of the rotors can be realized, and the controlexperiment and observation can be better carried out.

Description

technical field [0001] The invention relates to the technical field of bearings, in particular to a zero-friction superconducting magnetic suspension bearing device. Background technique [0002] Magnetic suspension bearings use magnetic force to suspend the rotor in the air. There is no mechanical contact between the rotor and the stator. Compared with traditional sliding bearings or rolling bearings, it has high speed, high precision, low power consumption, no mechanical contact, no lubrication, etc. advantage. With the continuous improvement of magnetic suspension bearings, they are widely used in many fields. With the development of superconducting technology, the improvement of equipment manufacturing process and system construction level, the application capability of maglev technology has been improved more rapidly. [0003] Traditional magnetic bearings require 5 or 10 non-contact position sensors to detect the displacement of the rotor. Due to the existence of th...
