Description

Self-aligning roller bearing inner ring

Technical Field

The utility model relates to a bearing inner ring, in particular to a self-aligning roller bearing inner ring.

Background

The self-aligning roller bearing is a bearing assembled with drum-shaped rollers between an inner ring with two raceways and an outer ring with spherical raceways. The self-aligning roller bearing is provided with two rows of rollers, and mainly bears radial load and can bear axial load in any direction. The bearing has high radial load capacity, is particularly suitable for working under heavy load or vibration load, but cannot bear pure axial load. The outer ring raceway of the bearing is spherical, so that the bearing has good aligning performance and can compensate the coaxiality error. The self-aligning roller bearing is generally used for paper making machinery, speed reducing devices, axles of railway vehicles, bearing seats of gear boxes of rolling mills, rollers of rolling mills, crushers, vibrating screens, printing machinery, woodworking machinery, speed reducers for various industries, vertical self-aligning bearings with seats and the like. The retainer of the conventional self-aligning roller bearing is generally limited outside a drum-shaped roller, and the outer wall of the drum-shaped roller is easy to rub the retainer when the drum-shaped roller rotates, so that the outer wall of the drum-shaped roller is abraded, and the rotation precision of the self-aligning roller bearing is further influenced; after drum-shaped rollers are seriously worn, the service life of the self-aligning roller bearing is also influenced, the inner ring of the conventional self-aligning roller bearing is generally of an integrated structure, but the cage cannot be limited on the outer wall of the inner ring.
