Embodiment Construction

[0009] Below according to accompanying drawing and specific embodiment the present invention is further described:

[0010] figure 1 The schematic diagram of the structure of the magnetic suspension combined ball bearing shown and figure 2 shown figure 1 The top view of the magnetic suspension combined ball bearing includes an inner ring (1), an outer ring (2) and balls (3). The ball (3) is dynamically fitted between the inner ring (1) and the outer ring (2). The inner ring (1) The center line of the outer ring (2) is the same, and the ball (3) is composed of an upper ball cover (4), a lower ball cover (5), a through pipe (6) and a moving magnetic pole (7), and the upper ball cover ( 4) Interference fit with the upper nozzle (8) of the through pipe (6), interference fit between the lower spherical cover (5) and the lower nozzle (9) of the through pipe (6), the moving magnetic pole (7) is located in the through pipe (6) In the cavity formed by the upper ball cover (4) and t...

Abstract

A magnetic suspension combined ball bearing comprises an internal ring, an external ring and balls that are movably matched between the internal ring and the external ring; the internal ring and the external ring have the same central line; the ball consists of an upper ball cover, a lower ball cover, a through pipe and a movable magnetic pole; the upper ball cover is matched with an upper nozzleof the through pipe in an interference fit mode; the lower ball cover is matched with an lower nozzle of the through pipe in the interference fit mode; the movable magnetic pole is arranged in a cavity that is formed by the through pipe, the upper ball cover and the lower ball cover; the internal ring is provided with an internal fixed magnetic pole; and the external ring is provided with an external fixed magnetic pole. As the ball is internally provided with the movable magnetic pole, the internal ring is provided with the internal fixed magnetic pole and the external ring is provided with the external fixed magnetic pole, the balls bear the repulsion force of the internal fixed magnetic pole of the internal ring and the suction force of the external fixed magnetic pole of the external ring so that the balls are suspended on the internal ring between the internal ring and the external ring, the radial pressure of the balls on the internal ring is reduced, and the service life of thebearing is prolonged.

Description

Technical field [0001] The invention relates to a bearing, in particular to a magnetic suspension combined ball bearing. Background technique [0002] When the existing bearing is used, the balls of the bearing are subjected to radial pressure, which is easy to wear the balls. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, provide a magnetic suspension combined ball bearing, and reduce the radial pressure on the bearing balls. [0004] The technical scheme adopted by the present invention is: magnetic suspension combined ball bearing, including inner ring, outer ring and balls, the balls are dynamically fitted between the inner ring and the outer ring, the centerlines of the inner ring and the outer ring are the same, and the balls are formed by the upper ball The cover, the lower spherical cover, the through pipe and the moving magnetic pole are composed of the upper spherical cover and the upper ...
