Radial-bearing flexible protecting bearing for magnetic suspension high-speed rotating equipment

Abstract

The invention discloses a radial-bearing flexible protecting bearing for magnetic suspension high-speed rotating equipment. The radial-bearing flexible protecting bearing is an integrally machined structural component and is characterized in that a bearing outer ring, a bearing inner ring and flexible reeds are designed on the protecting bearing, wherein the flexible reeds are arranged between the bearing outer ring and the bearing inner ring, external gaps are formed between the flexible reeds and the bearing outer ring, and internal gaps are formed between the flexible reeds and the bearing inner. According to the radial-bearing flexible protecting bearing, a flexible reed structure is designed between the bearing inner ring and the bearing outer ring, and the joints between the flexile reeds and the bearing inner ring are flexible formation point, so that when great impact is caused because a rotor is unstable, lots of kinetic energy of the rotor can be absorbed by virtue of the elastic deformation of the flexible reeds, without damaging other parts in the equipment.

Description

technical field [0001] The invention relates to a bearing, more particularly, to a radial load flexible protective bearing used 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, which improves the mech...

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
