A self-lubricating bearing

Abstract

The invention relates to a self-lubricating bearing which comprises an outer ring, an inner ring, a holder and rolling bodies. The outer ring and the inner ring are each of a circular structure. The inner diameter of the outer ring is larger than the outer diameter of the inner ring. The rolling bodies are evenly mounted between the outer ring and the inner ring and are fixedly mounted on the holder. According to the self-lubricating bearing, the problems that during oil injection of an existing bearing, oil injection is inconvenient, the sealing effect of a bearing inner cavity is poor after oil injection, lubricating oil is prone to overflowing out, consequently, the lubricating oil is wasted, surroundings are contaminated, when the existing self-lubricating bearing is used, the self-lubricating effect is poor, liquid output of the lubricating oil is not stable, and the self-lubricating bearing is hard to machine and high in production cost can be solved; and the self-lubricating bearing has the advantages that the lubricating effect is achieved, oil output is stable, and the phenomenon of oil leaking cannot happen.

Description

technical field [0001] The invention relates to the technical field of bearings, in particular to a self-lubricating bearing. Background technique [0002] Bearing lubrication mainly includes grease lubrication and oil lubrication. Grease lubrication needs to be filled with grease regularly, and oil lubrication needs to be pumped by setting an oil throwing ring or soaking the bearing in an oil pool to force lubrication through an oil wedge, and the oil will splash strongly. It not only wastes lubricating oil but also pollutes the environment. Therefore, self-lubricating bearings are usually used in places where it is difficult to form an oil film such as reciprocating motion, rocking motion, and frequent starting and stopping. [0003] At present, the existing self-lubricating bearings usually have the following defects when in use: 1. When the existing bearings are filled with oil, it is inconvenient to fill the oil. 2. When the existing self-lubricating bearings are used,...

AI Technical Summary

Problems solved by technology

[0005] The present invention can solve the problem of inconvenient oil filling for the existing bearings, poor sealing effect of the inner cavity of the bearing after oil filling, and easy overflow of lubricating oil, resulting in waste of lubricating oil and pollution of the surrounding environment, and the existing self-lubricating bearings are When in use, the self-lubricating effect is poor, the lubricating oil is not stable, and the self-lubricating bearing is difficult to process and the production cost is high.
