Semi-ring coupled precision rolling bearing

Abstract

The invention discloses a semi-ring coupled precision rolling bearing. The semi-ring coupled precision rolling bearing comprises a bearing inner ring, a bearing outer ring, a rolling element positioned between the bearing inner ring and the bearing outer ring as well as a retainer, wherein the bearing inner ring is formed by connecting an inner ring semi-ring a and an inner ring semi-ring b; the bearing outer ring is formed by connecting an outer ring semi-ring a and an outer ring semi-ring b. The semi-ring coupled precision rolling bearing disclosed by the invention is convenient and simple to assemble and disassemble; the semi-ring coupling surface of the bearing inner ring can be laminated with the semi-ring coupling surface of the bearing outer ring and self positioning of the couplingsurface is realized, so that the bearing inner ring has higher roller path docking precision and the semi-ring coupling surface of the inner ring is enabled to have higher coupling rigidity of the coupling surface.

Description

technical field [0001] The invention belongs to the field of mechanical structures, and in particular relates to a half-ring connection type precision rolling bearing. Background technique [0002] Bearings are an important part of contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. Bearings can be divided into two categories: rolling bearings and sliding bearings. Rolling bearings are generally composed of four parts: outer ring, inner ring, rolling elements and cages. According to the shape of rolling elements, rolling bearings are divided into two categories: ball bearings and roller bearings. [0003] The inner ring and outer ring of common rolling bearings are integral rings. When installing the bearing, the inner ring of the bearing usually needs to have an interference fit with the shaft, which makes it difficult to install and disassem...
