Spring-clip-limited dustproof rolling bearing

Abstract

The invention discloses a dust-proof rolling bearing with a spring card position limit, which comprises: a bearing outer ring and a bearing inner ring, the bearing inner ring is concentrically arranged in the bearing outer ring, the bearing outer ring inner wall and the bearing inner ring There is a circle of cylindrical swivels between them for rolling connection, and the outer ring of the bearing is provided with sealing rings on both sides of the cylindrical swivels, and balls are respectively arranged between the inner surface of the sealing ring and the end of the cylindrical swivels. Rolling connection, the outer ring of the bearing is respectively provided with spring clips located outside the sealing ring. The dust-proof rolling bearing with a spring clip limit according to the present invention uses a spring clip to limit the position of the sealing ring, thereby improving the structural stability and dust-proof sealing effect of the sealing ring. The rotation resists the friction of the cylindrical swivel, improves the axial support of the cylindrical swivel, and has good structural stability.

Description

technical field [0001] The invention relates to the field of bearings, in particular to a dust-proof rolling bearing limited by a spring clip. Background technique [0002] Bearing is an important part of contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during the movement of the mechanical rotating body, and ensure its rotation accuracy. [0003] According to the different friction properties of moving elements, bearings can be divided into two categories: rolling bearings and sliding bearings. Among them, rolling bearings have been standardized and serialized, but compared with sliding bearings, their radial size, vibration and noise are larger, and the price is also higher. . [0004] Rolling bearings are generally composed of four parts: outer ring, inner ring, rolling elements and cage. The effect of radial support is good, but it is difficult to bear large axial force, and the dustproof ab...

[0003] According to the different friction properties of moving elements, bearings can be divided into two categories: rolling bearings and sliding bearings. Among them, rolling bearings have been standardized and serialized, but compared with sliding bearings, their radial size, vibration and noise are larger, and the price is also higher.

[0004] Rolling bearings are generally composed of four parts: outer ring, inner ring, rolling elements and cage. The effect of radial support is good, but it is difficult to bear large axial force, and the dustproof ability is limited.
