Bearing convenient to lubricate

Abstract

The invention discloses a bearing convenient to lubricate, and solves the problems that lubricating oil cannot be dropwise added at regular times, and cannot be automatically dropwise added on a rolling column, friction coefficients are high, and noises are generated. The bearing convenient to lubricate comprises an outer ring, wherein an oil injection opening is formed in the surface of the outerring; a hinge is arranged on one side of the oil injection opening; a protective cover is mounted on the side, which corresponds to the oil injection opening, of the hinge; a fixing buckle is arranged on the side, which is away from the hinge, of the protective cover; a third sealing ring is embedded in the inner side of the protective cover; an oil storage groove is formed in the position, whichcorresponds to the oil injection opening, of the inside of the outer ring; an oil outlet is formed in one side of the oil storage groove; a drainage tube is arranged on the side, which is away from the oil storage groove, of the oil outlet; a throttling valve is mounted in the drainage tube; a ball seat is arranged at the tail end of the drainage tube; a steel ball is mounted in the middle of theball seat; an inner ring is arranged on the inner side of the outer ring; rollers are mounted between the inner ring and the outer ring; limiting pieces are arranged among the rollers; the sides, which are away from the inner ring, of the rollers are clamped in a groove; and space between the second sealing ring and the inner ring is filled with sound-absorbing cotton.

Description

technical field [0001] The invention relates to the technical field of bearings, in particular to a bearing which is convenient for lubrication. Background technique [0002] Bearings are components that fix and reduce the friction coefficient of loads during mechanical transmission. It can also be said that when other parts move relative to each other on the shaft, it is used to reduce the friction coefficient in the process of power transmission and keep the center of the shaft fixed. Bearing is an important component in contemporary mechanical equipment. Its main function is to support the mechanical rotating body to reduce the friction coefficient of mechanical load during the transmission process of the equipment. According to the different friction properties of moving elements, bearings can be divided into rolling bearings and sliding bearings. Bearings generally include inner rings and outer rings, and rolling elements are arranged between the inner rings and outer ...

AI Technical Summary

Problems solved by technology

[0004] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a bearing that is easy to lubricate, which effectively solves the problem that lubricating oil cannot be dripped regularly, and the lubricating oil cannot be dripped on the rollers by itself. The friction coefficient is large, and there will be certain noise generation problem
