A radial shaft integrated flexible protective bearing for magnetic levitation high-speed rotating equipment

Abstract

The invention discloses a radial-shaft integrated flexible protective bearing for magnetic levitation high-speed rotating equipment. The protective bearing is integrally processed into a structural member; the protective bearing is designed with a bearing outer ring (1) and a bearing inner ring (2). ), a Z-shaped structure (3) and a hollow groove (8); the Z-shaped structure (3) is placed between the bearing outer ring (1) and the bearing inner ring (2), and the Z-shaped structure (3 ) and the bearing outer ring (1) have an outer annular groove (4), and the Z-shaped structure (3) and the bearing inner ring (2) have an inner annular groove (5); the hollow groove (8) is spaced Place it between the bearing outer ring (1) and the bearing inner ring (2). The protective bearing designed in the present invention can absorb a large amount of kinetic energy of the rotor by using the elastic deformation of the Z-shaped structure itself when the rotor is unstable and produces a huge impact, so as not to damage other parts inside the equipment.

Description

technical field [0001] The invention relates to a bearing, more particularly, to a flexible protection bearing integrated with a diameter and shaft for magnetic levitation high-speed rotating equipment. Background technique [0002] In recent years, due to the advancement of magnetic levitation technology, direct drive high-speed rotating equipment such as high-speed magnetic levitation blowers / compressors, ultra-high vacuum molecular pumps, magnetic levitation energy storage flywheels, and magnetic levitation moment gyroscopes have achieved considerable development. Magnetic levitation technology specifically refers to magnetic levitation bearing (or magnetic bearing) technology, which uses electromagnetic force to levitate the rotor to replace traditional mechanical bearing support. Magnetic bearings can overcome the disadvantage of large friction loss of mechanical bearings. During operation, the rotor does not have any mechanical contact, no friction, no lubrication, whi...

AI Technical Summary

Problems solved by technology

May cause mechanical damage to the bearing cage

Make the rotor continue to collide with other components inside the equipment, such as magnetic bearings and motor stators, resulting in scrapped equipment

Or due to frictional heat, the balls and bearings will expand, resulting in the protection of the bearings stuck and stalled
