Self-sealing lubricating high-temperature rolling bearing and manufacturing method thereof

Abstract

The invention discloses a self-sealing lubricating high-temperature rolling bearing and a manufacturing method thereof. The self-sealing lubricating high-temperature rolling bearing comprises a bearing main body, wherein a lubricating mechanism and a flow guide mechanism are arranged in the bearing main body, and a sealing mechanism is arranged on the side wall of the bearing main body. The flow guide mechanism comprises a driving assembly and a flow guide assembly which are arranged in the bearing body, wherein the driving assembly and the flow guide assembly are meshed with each other. The flow guide assembly comprises a driving rod, wherein the driving rod is driven by the driving assembly, an impeller is fixedly installed on the side wall of the driving rod, and a first bevel gear is fixedly connected to the end of the driving rod. The sealing mechanism comprises sealing plates which are oppositely arranged on the side wall of the bearing main body, and sealing teeth are arranged on the side walls of the two sealing plates. Lubricating oil is discharged through connecting grooves, circulation of the lubricating oil between an outer ring and an inner ring is achieved in the process, the heat dissipation area of the outer ring can be effectively increased through heat dissipation grooves, and therefore the temperature of the lubricating oil is reduced, the protection function on a bearing is achieved, and the service life of the bearing is prolonged.

Description

technical field [0001] The invention relates to the technical field of bearings, in particular to a self-sealing lubricating high-temperature rolling bearing and a manufacturing method thereof. 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. According to the different friction properties of moving elements, bearings can be divided into two categories: rolling bearings and sliding bearings; [0003] The additional sealing device supported by the bearing can effectively prevent the intrusion of foreign matter from the outside, but this additional sealing device will increase the axial dimension of the mechanism, which will bring inconvenience to the use, installation and maintenance of the bearing, and its sealing performance will also be affected by the shaft diameter and housing...
