Sealing structure of bearing pedestal

Abstract

The invention is applicable to the technical field of bearing pedestals and provides a sealing structure of a bearing pedestal. The sealing structure comprises a sealing cover, a sealing ring, an adjusting sleeve, a sealing circle, a bearing, the bearing pedestal, an end cover and a sphere. When the sealing structure is used, under the effect of the sphere, sliding friction between the sealing cover and the sealing ring is changed into rolling friction, and thus the sealing ring rotates more smoothly; a storing groove is formed in the bottom of a sliding groove, sealing oil injected into the sliding groove can be stored, in the rotating process of the sealing ring, the sphere is driven to move synchronously, the exposed portion of the sphere rotates into the storing groove and makes contact with the sealing oil in the storing groove, the oil stored in the storing groove lubricates the sphere, along with rotating of the sealing ring, the lubricated part is rotated out, and makes contactwith the inner wall of the sliding groove formed in the sealing ring, friction force between the sealing ring and the sealing cover is reduced greatly, and the dustproof effect on the bearing is further improved.

Description

technical field [0001] The invention belongs to the technical field of bearing seats, and in particular relates to a sealing structure of a bearing seat. Background technique [0002] The turntable bearing seat is a large and extra large bearing seat that can accept comprehensive loads and has a special structure. It has the characteristics of compact structure, sensitive rotation, and convenient maintenance of the device. Where there is a bearing, there must be a support point. The inner support of the bearing The point is the shaft, and the outer support is the so-called bearing seat. [0003] At present, during the use of hoist bearings on the market, the rotation of the sealing ring is not smooth enough, so that dust will still enter the inside of the bearing through the sealing ring. Contents of the invention [0004] The invention provides a sealing structure of a bearing housing, which aims to solve the problem that the rotation of the sealing ring is not smooth en...
