Self-lubricating bearing

Abstract

The invention relates to a self-lubricating bearing. The self-lubricating bearing comprises an outer ring, an inner ring and a rolling body, wherein the rolling body is arranged between the outer ring and the inner ring. A first oil storage ring used for storing lubricating grease is fixedly connected with the end face of the outer ring, the central axis of the outer ring is parallel to the central axis of the first oil storage ring, and a plurality of first S-shaped oil outlet channels used for supplying the lubricating grease in the first oil storage ring to the rolling body are formed in the outer ring. Because of existence of the first S-shaped oil outlet channels, the lubricating grease in the first oil storage ring supplied to the rolling body is stopped when the rolling body does not rotate, and when the rolling body moves, negative pressure is formed between the inner ring and the outer ring, so that the first S-shaped oil outlet channels are connected, and the lubricating grease in the first oil storage ring is supplied to the rolling body; and the higher the rotating speed of the rolling body is, the larger the negative pressure formed between the inner ring and the outer ring is, the flow rate of the lubricating grease passing through the first S-shaped oil outlet channels is higher, and therefore the bearing can conduct self-supplying of the lubricating grease according to the movement state and the movement speed of the rolling body.

Description

technical field [0001] The invention relates to a bearing, in particular to a self-lubricating bearing. Background technique [0002] Bearings can be seen everywhere in today's society. The current bearings that can achieve self-lubrication are often oil-impregnated bearings. Oil-impregnated bearings are sintered bodies made by powder metallurgy. For lubricating rolling elements. Its shortcoming is: because the oil-impregnated bearing cannot supply lubricating grease according to the motion state of the rolling elements, and the containing bearing cannot supply lubricating grease according to the speed of the rolling elements. Contents of the invention [0003] The purpose of the present invention is to provide a self-lubricating bearing that can supply lubricating grease according to the motion state and speed of the rolling elements. [0004] In order to realize the above-mentioned purpose of the invention, the technical scheme that the present invention takes: [000...

AI Technical Summary

Problems solved by technology

Its shortcoming is that since the oil-containing bearing cannot supply lubricating grease according to the motion state of the rolling elements, at the same time, the containing bearing cannot supply lubricating grease according to the speed of the rolling element movement.
