Conical surface deviation-eliminating rolling bearing

Abstract

The invention relates to a bearing, and in particular relates to a conical surface deviation-eliminating rolling bearing which can eliminate the radial play eccentricity of a bearing outer ring and is easy to assemble and disassemble. The conical surface deviation-eliminating rolling bearing solves the problems that a large-sized bearing is unfavorable for assembly and disassembly and the axis deviates due to radial run-out and size deviation of the outer ring of the large-sized bearing. According to the technical scheme, the conical surface deviation-eliminating rolling bearing comprises an inner ring, a rolling body, a retainer, an outer ring and spacers. The end surface, matched with an outer mounting base, of the outer ring is designed into a conical surface with a taper; and a plurality of spacers are uniformly distributed in the circumferential direction of the small end surface of the outer ring and fixedly connected to the outer ring, and the thickness of the spacer can be set as required. The axis deviation caused by the run-out and size deviation of the outer ring of the bearing is eliminated, and the positioning precision and supporting rigidity of the bearing are improved.

Description

technical field [0001] The invention relates to a bearing, in particular to a tapered surface anti-difference rolling bearing which can eliminate the radial runout of the outer ring of the bearing and is easy to assemble and disassemble. Background technique [0002] With the rapid development of various manufacturing industries in our country and the continuous upgrading of peripheral products in the machinery industry and electronics industry, the quality requirements for bearings are also getting higher and higher. Especially in extreme manufacturing fields such as aerospace, navigation, and aviation, the demand for large bearings is also increasing. At present, although some domestic and foreign manufacturers can supply large-scale bearings, it is often difficult to meet engineering needs due to various disadvantages. These disadvantages are mainly manifested as follows: [0003] 1. It is not conducive to bearing disassembly. For large bearings, it is generally imposs...

AI Technical Summary

Problems solved by technology

[0006] Aiming at the problem that ordinary large bearings at home and abroad are difficult to disassemble by traditional installation methods, and because of their low precision and large radial runout of the outer ring, it is difficult to meet the requirements of engineering practice for the coaxiality of the system. The invention provides a tapered surface Differential Rolling Bearings

[0007] The technical problem solved by the present invention is to design a tapered anti-difference rolling bearing, which effectively solves the problem that large bearings are not conducive to assembly and disassembly, and the problem of axial deviation caused by the radial runout and size deviation of the outer ring of large bearings, and improves the bearing capacity. Excellent rigidity and positioning accuracy, and easy to assemble and disassemble
