Wear-resistant bearing

Abstract

The invention relates to the technical field of bearings, in particular to a wear-resistant bearing. The wear-resistant bearing comprises a bearing body, wherein an upper connecting shell is arrangedat the upper end of the bearing body, a lower connecting shell is arranged at the lower end of the upper connecting shell, a connecting strip is arranged on the outer surface of the bearing body, connecting rings are arranged on the outer surfaces of the inner walls of the upper connecting shell and the lower connecting shell, connecting openings are formed in the outer surfaces of the connectingrings, an oil filling structure is arranged at the upper end of the upper connecting shell, and the oil filling structure comprises an oil storage bottle, a connecting cover, an oil guide pipe, a first flow guide hole and a second flow guide hole. According to the wear-resistant bearing, through the action of the connecting strip, the connecting rings and the connecting openings, the bearing bodycan be installed more conveniently, meanwhile, the bearing body which is used for a long time can be replaced more conveniently, through the matching action of the oil filling structure, oil filling of the bearing can be completed more conveniently, so that the lubricating effect of the bearing is better, then the abrasion caused by excessive drying of the bearing is avoided, and the practicability effect is relatively strong.

Description

technical field [0001] The invention relates to the technical field of bearings, in particular to a wear-resistant bearing. Background technique [0002] Bearing is 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 rolling bearings There are two types of sliding bearings and sliding bearings. Among them, rolling bearings have been standardized and serialized, but compared with sliding bearings, their radial size, vibration and noise are larger, and the price is also higher. Rolling bearings are generally composed of four parts: outer ring, inner ring, rolling body and cage. Strictly speaking, they are composed of six parts: outer ring, inner ring, rolling body, cage, seal, and lubricating oil. Rings and rolling elements can be ...

[0002] Bearing is 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 rolling bearings There are two types of rolling bearings and sliding bearings. Among them, rolling bearings have been standardized and serialized, but compared with sliding bearings, their radial size, vibration and noise are larger, and the price is also higher.

Rolling bearings are generally composed of four parts: outer ring, inner ring, rolling body and cage. Strictly speaking, they are composed of six parts: outer ring, inner ring, rolling body, cage, seal, and lubricating oil. Rings and rolling elements can be defined as rolling bearings. According to the shape of rolling elements, rolling bearings are divided into two categories: ball bearings and roller bearings; First, the installation and use of the existing wear-resistant bearings is not convenient enough, which in turn causes inconvenience in use; second, the existing wear-resistant bearings usually need to be disassembled and replaced after a certain period of use, but the disassembly and replacement process is relatively inconvenient; third , it is inconvenient to add lubricating oil for wear-resistant bearings. For this reason, we propose a wear-resistant bearing
