Title:
HIGH-SPEED BEARING
Document Type and Number:
WIPO Patent Application WO/2023/179408
Kind Code:
A1
Abstract:
A high-speed bearing, comprising a first rotating shaft (1), a first bearing assembly (2), a second bearing assembly (3) and a bearing seat (4). An inner ring of the first bearing assembly (2) rotates synchronously with the first rotating shaft (1); an outer ring of the first bearing assembly (2) rotates synchronously with an inner ring of the second bearing assembly (3); an outer ring of the second bearing assembly (3) is connected to the bearing seat (4); a plurality of first permanent magnets (6) are uniformly arranged on the first rotating shaft (1) in the circumferential direction; a plurality of second permanent magnets (7) are uniformly arranged on the outer ring of the first bearing assembly (2) in the circumferential direction; a plurality of magnetizer (8) are uniformly arranged on an inner wall surface of the bearing seat (4) in the circumferential direction; each magnetizer (8) comprises a U-shaped steering portion (801); one of the two opposite side walls of the U-shaped steering portion (801) corresponds to the position of a first permanent magnet (6), and the other side wall corresponds to the position of a second permanent magnet (7). According to the high-speed bearing, the U-shaped steering portions (801) of the magnetizers (8) are adopted to steer a magnetic field, so that the inner ring of the second bearing assembly (3) and the first rotating shaft (1) rotate in a same direction, an upper limit of a power input rotating speed which can be borne by the bearing is also improved, the service life is not reduced, the production cost is low, and an application range is wide.
