A half-ring coupling type precision rolling bearing

Abstract

The invention discloses a semi-ring connection type precision rolling bearing, which comprises a bearing inner ring, a bearing outer ring, a rolling body and a cage between the bearing inner ring and the bearing outer ring, and the bearing inner ring is composed of an inner ring half ring a and an inner ring The ring and half ring b are connected to form, and the outer ring of the bearing is formed by connecting the outer ring half ring a and the outer ring half ring b. The half-ring connection type precision rolling bearing of the present invention is convenient and simple to install and disassemble, and the half-ring connection surfaces of the bearing inner ring and the outer ring can fit each other to realize the self-positioning of the connection surface, so that the bearing inner ring has a higher raceway butt joint Accuracy, but also to ensure that the inner ring semi-ring connection surface has a high connection surface connection stiffness.

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...
