Bearing and bearing outer ring

Abstract

The embodiment of the invention provides a bearing and a bearing outer ring. The bearing outer ring comprises a bearing outer ring body and an lubricating oil containing part, wherein a lubricating oil hole is formed in a roller way part of the bearing outer ring body; the lubricating oil containing part is fixed on the end surface of the bearing outer ring body; the lubricating oil containing part comprises an inner surface and an outer surface which are arranged along the radial direction of the bearing outer ring body; the axial distance of the inner surface and the bearing outer ring bodyis larger than or equal to the radius of the inner ring surface of the bearing outer ring body; the axial distance of the outer surface and the bearing outer ring body is smaller than or equal to theradius of the outer ring surface of the bearing outer ring body; the lubricating oil hole communicates with a roller way space of the bearing outer ring body and a containing cavity of the lubricatingoil containing part; and roller way oil ports of the lubricating oil hole is located between the inner surface and the outer surface. According to the bearing and the bearing outer ring, the lubricating effect of the bearing is ensured, impurity removal is facilitated, and meanwhile, the sealing requirement is reduced.

Description

technical field [0001] The embodiments of the present invention relate to the field of electromechanical equipment, in particular to a bearing and an outer ring of the bearing. Background technique [0002] Bearing is an important part of mechanical equipment, which is set between the parts that generate relative rotation. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement and ensure its rotation accuracy. [0003] In order to reduce the friction force during the operation of the bearing, lubricating materials are used for lubrication, and lubricating oil or grease is injected between the inner ring of the bearing and the outer ring of the bearing, thereby reducing the friction force during the operation of the bearing. [0004] However, in grease-lubricated bearings, due to the high viscosity of the grease, the friction of the bearing is relatively high, and the heat dissipation is also poor. The replacement pro...

Problems solved by technology

[0004] However, in grease-lubricated bearings, due to the high viscosity of the grease, the friction of the bearing is high, and the heat dissipation is also poor. The replacement process of the grease is also complicated. In addition, when impurities enter the bearing Finally, it is difficult to use grease to take away impurities; and in bearings using lubricating oil, the problem of lubricating oil leakage is prone to occur, and the requirements for sealing quality are relatively high.
