Self-aligning roller bearing capable of adjusting clearance

Abstract

The invention discloses a self-aligning roller bearing with an adjustable clearance. The self-aligning roller bearing comprises a bearing seat, and an inner ring and an outer ring which are coaxially arranged, wherein a positioning step is formed at one end of the bearing seat, the outer ring is arranged in a split mode to form two outer sub-rings, the two outer sub-rings are both installed on the bearing seat, one outer sub-ring abuts against the positioning step, roller paths are arranged at the positions, corresponding to the two outer sub-rings, of the outer wall of the inner ring, retainers are arranged between the two outer sub-rings and the inner ring, rollers are arranged in the retainers and rotationally matched with the roller paths, the other end of the bearing seat is in threaded fit with an adjusting check ring, the adjusting check ring abuts against the side walls of the outer sub-rings, a pressing ring used for fastening the adjusting check ring is further arranged on the bearing seat, and dustproof covers are arranged between the positioning step and the inner ring and between the pressing ring and the inner ring. The clearance is convenient to adjust, and meanwhile, the structure is simple, operation is convenient and fast, and the use effect of the product is improved.

Description

technical field [0001] The invention relates to the technical field of bearings, in particular to a self-aligning roller bearing with adjustable clearance. Background technique [0002] Commonly used standard design spherical roller bearings, the outer ring is an integral outer ring, the bearing mainly bears radial load, and can also bear axial load in any direction. It has high radial load capacity and is suitable for working under heavy load or vibration load. It has good self-alignment performance and can compensate for coaxiality errors. However, the outer ring of the existing self-aligning roller bearing is an integral outer ring, and the clearance cannot be adjusted after matching, so that the dispersion of the clearance of the bearing is relatively large. Reduce the use effect of spherical roller bearings, so that the overall defective rate is high, and it is difficult to improve production and processing efficiency. Contents of the invention [0003] Aiming at th...
