Novel steering waterproof sealed bearing as well as preparation method and application thereof

Abstract

The invention provides a novel steering waterproof sealed bearing which comprises a bearing outer ring and a bearing inner ring, wherein the bearing outer ring is formed by combining a cylindrical side wall with a ring-shaped top wall; the ring-shaped top wall is connected with one end of the cylindrical side wall; an arc shape is formed at the joint between the ring-shaped top wall and the cylindrical side wall; the inner ring diameter of the ring-shaped top wall is the same as the inner diameter of the bearing inner ring; a rolling body is arranged between the bearing outer ring and the bearing inner ring; the working state of the rolling body is kept through a retainer; a ring-shaped sealing ring is mounted at the bottom end of the bearing inner ring; a sealing ring clamp groove is formed in the inner side of the bearing outer ring; the outer side of the sealing ring is clamped into the sealing ring clamp groove in the inner side of the bearing outer ring; the inner side of the sealing ring is in close contact with the bearing inner ring; and an outer flange is formed. The invention further provides a preparation method and application of the above novel steering waterproof sealed bearing. The novel steering waterproof sealed bearing provided by the invention can be protected from damage caused by rainwater or mud invasion; the vehicle steering performance can be effectively improved; and compared with a currently-applied steering bearing, the novel steering waterproof sealed bearing has the advantage that the service life can be prolonged by 10 times or above.

Description

technical field [0001] The invention belongs to the technical field of bearings, in particular to a novel steering waterproof sealed bearing and its preparation method and application. Background technique [0002] At present, in some fields, when bearings are applied, the problems of dustproof, waterproof and mudproof bearings have been considered, and they are generally in the field of large-scale instrument technology. But in some fields of production and living technology, the problems of bearing dustproof, waterproof and mudproof have not been taken seriously. For example, for some vehicles such as electric vehicles, most of the applications of electric vehicles are outdoors, and they often encounter muddy roads, rain, etc. At the steering bearing of electric vehicles, the problem of waterproofing and mud resistance has not been considered at present. The flexibility of electric vehicle steering bearings is related to the safety of riding. Contents of the invention ...
