Problems solved by technology

[0005] Current magnetic suspension bearings usually include permanent magnetic suspension bearings, electromagnetic suspension bearings and hybrid magnetic suspension bearings. Electromagnetic suspension bearings and hybrid magnetic suspension bearings usually require a complete set of monitoring and control systems, which are not only complex in structure, large in size, and high in cost; Chinese patent CN 202451603 U, this patent introduces a combined magnetic suspension bearing, which is small in size, easy to install and adjust, and has good interchangeability, but the patent has a ring groove on the thrust end surface of the inner ring, and the The ring groove is very difficult, not only difficult to process precisely, but also limits the rotation accuracy

Abstract

The invention discloses a precision integrated magnetic floating bearing and relates to the technical field of bearings. The precise integrated magnetic floating bearing comprises an outer ring (1), an inner ring (10), a ring seat A (2), a ring seat B (16) and a screw (3), wherein the outer ring (1) which is in running fit with the inner ring (10) is arranged at the exterior of the inner ring (10); the ring seat A (2) and the ring seat B (16) which are fixedly connected with each other by virtue of screws (3) are respectively arranged at two ends of the outer ring (1). The precise integrated magnetic floating bearing is compact in structure, simple in structure and convenient for processing and mounting; furthermore, the rotating precision of the precision integrated magnetic floating bearing is obviously improved.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of bearings, in particular the invention relates to a precision integrated magnetic suspension bearing. [0003] 【Background technique】 [0004] As is known, magnetic suspension bearings use magnetic force to suspend the rotor in the air, so that there is no mechanical contact between the rotor and the stator. The principle is that the magnetic induction line is perpendicular to the magnetic levitation line, and the shaft core is parallel to the magnetic levitation line, so the weight of the rotor is Fixed on the running track, use the almost no-load shaft core to support the direction of the anti-magnetism floating line, forming the entire rotor suspended in the air, on the fixed running track; compared with traditional rolling bearings, sliding bearings and joint bearings, magnetic suspension bearings are not There is mechanical contact, and the rotor can run to a very high speed. It has the advant...
