Wide-outer-ring long-service-life bearing with clearance adjusting function

Abstract

The invention provides a wide-outer-ring long-service-life bearing with a clearance adjusting function, which comprises an outer ring, an inner ring and steel balls arranged between the outer ring and the inner ring, raceways corresponding to the steel balls are arranged on the inner side of the outer ring and the outer side of the inner ring, more than two raceways are arranged on the inner side of the outer ring, the more than two raceways are coaxially arranged, and the clearance adjusting function is realized between the outer ring and the inner ring. The diameters of at least two of the more than two raceways are different; the size of the bearing clearance of the bearing is adjusted by switching the raceways of the steel balls. According to the wide-outer-ring long-service-life bearing with the clearance adjusting function, the multiple outer ring raceways are arranged, and axial displacement can be achieved while rotation of the bearing inner ring is achieved; the bearing has the characteristics of a deep groove ball bearing, and meanwhile, the self-aligning angle larger than that of a common deep groove ball bearing can be achieved; a plurality of raceways are arranged, so that the ultra-long service life of the bearing can be realized.

Description

technical field [0001] The invention belongs to the technical field of aerospace bearings, in particular to a wide outer ring long-life bearing with a clearance adjustment function. Background technique [0002] With the vigorous development of my country's aerospace industry, aerospace precision bearings play a pivotal role as mechanical joints, and are widely used in aircraft motors, execution systems, transmission and control systems and other fields. [0003] As aircraft operate more accurately and fly farther and farther, long life and high precision are particularly important. Bearings have always existed as standard parts in the traditional mechanical field, but the stricter requirements in the aerospace field have also made the inherent form of traditional bearings a serious obstacle to restricting the development of the field. SUMMARY OF THE INVENTION [0004] In view of this, the present invention aims to provide a wide outer ring long-life bearing with a cleara...
