Insert bearing with tooth-shaped sealing cover

Abstract

The invention relates to the field of bearings, in particular to an insert bearing with a tooth-shaped sealing cover used for a farm machine, which is provided with an inner ring, an outer ring, a rolling element arranged between the inner ring and the outer ring, a retainer supporting the rolling element, and a sealing ring arranged on the periphery of the rolling element and used for sealing, wherein the sealing ring comprises a sealing cover and a sealing lip which is fixed on the inner side of the sealing cover; the sealing cover is riveted on the inner surface of the outer ring in a tooth-shaped contact mode through mould pressing of a gland bush; the sealing lip is sealed on the outer surface of the inner ring in a contact mode; the inner surface of the outer ring is provided with a groove; the outer surface of the sealing cover is provided with a tooth-shaped heave used for clamping into the groove; and the sealing cover is pressed into the groove through a gland bush mold, and the sealing lip has a three-lip structure. The insert bearing has the advantages that the insert bearing has high sealing performance and is suitable to work in severe environments; the sealing performance under large torque cannot be reduced; and the working life of the bearing is long.

Description

technical field [0001] The invention relates to the field of bearings, in particular to an outer spherical bearing with a gear seal cover used in agricultural machinery. Background technique [0002] At present, the application of bearings in the market is becoming more and more extensive, especially in the matching of main equipment such as pump machinery, oil field machinery and agricultural machinery. In the case of harsh working environment, the technical quality requirements of the bearing are particularly high, especially the sealing performance of the bearing. It is easy to loosen in the bearing, and the fastening screw of the inner ring of the bearing is prone to overload and cracking when the bearing is working, which makes the performance of the seal deteriorate. At the same time, the bearing is easily damaged and the service life is short. Contents of the invention [0003] The technical problem to be solved by the present invention is: in order to solve the ab...
