Embodiment Construction

[0014] The present invention provides a sealing structure for cylindrical rollers 3, including an outer ring 1, an inner ring 2, and double-row rollers 3. The double-row rollers 3 are rolled between the outer ring 1 and the inner ring 2. The two ends of the outer peripheral wall of the ring 2 protrude toward the inner peripheral wall of the outer ring 1 with retaining rings 11, and the end faces of the retaining rings 11 are set in cooperation with the inner peripheral wall of the outer ring 1, and the end faces of the retaining rings 11 are recessed with annular grooves 111. Each of the annular grooves 111 is provided with an isolating ring 2, the isolating ring 2 is made of elastic material, a part of the outer peripheral wall of the isolating ring 2 is connected with the inner peripheral wall of the outer ring 1, and the other part is buckled in the annular groove 111 On the inner wall, the spacer ring 2 is provided with an opening 21, the spacer ring 2 is in the shape of a ...

Abstract

The invention discloses a sealing structure of a cylindrical roller. The sealing structure comprises an outer ring, an inner ring and double rows of rollers, the double rows of rollers are arranged between the outer ring and the inner ring in a rolling mode, the two ends of the outer circumferential wall of the inner ring protrude towards the inner circumferential wall of the outer ring to form baffle rings, the end surfaces of the baffle rings are in clearance fit with the inner circumferential wall of the outer ring, annular grooves are formed in the end surfaces of the baffle rings in a sunken mode, isolation rings are arranged in the two annular grooves and made of elastic materials, one part of the outer circumferential wall of each isolation rings is connected with the inner circumferential wall of the outer ring, the other parts of the outer circumferential walls of the isolation rings abut against the inner walls of the annular grooves, openings are formed in the isolation rings, and the isolation rings are in arc ring shapes. The problem that a bearing is damaged due to the fact that external impurities enter the bearing easily in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of bearings, in particular to a cylindrical roller sealing structure. 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. However, in the common NNUP type cylindrical roller bearing in the prior art, its inner ring and two retaining rings are separated from the outer ring, which is cumbersome in the bearing packaging, transportation and installation process. Moreover, this structure has no seal, and impurities and dust often enter the inner cavity of the bearing during use, which seriously affects the life of the bearing. When the NNUP type cylindrical roller bearing is working, due to its very harsh working environment, it is very easy for impurities such as sand and dust to enter the inner cavity of the bearing,...
