Problems solved by technology

However, when the rotating speed of the working shaft is low, since this self-lubricating material is solid and has no fluidity, it often cannot form a continuous lubricating picture, which affects the lubrication effect, causing the metal part of the bearing to directly rub against the working shaft, resulting in friction Chips, these friction chips will in turn affect the lubricating layer that has been formed, forming a vicious circle

Abstract

The invention discloses a self-lubricating bearing with continuous self-lubricating surfaces. The self-lubricating bearing comprises a base steel (1), and is characterized in that the inner wall of the base steel (1) is provided with multiple notches (2) along an axial direction of the base steel (1), wherein the notches (2) are uniformly distributed, the base steel (1) is internally provided with a self-lubricating layer (3), and the outer wall of the self-lubricating layer (3) is provided with multiple connecting bulges (4) which are matched with the notches (2). The self-lubricating bearing disclosed by the invention has the advantages of simple structure, skilled design, reasonable layout, and capability of forming continuous and uninterrupted self-lubricating surfaces on a friction surface.

Description

technical field [0001] The invention relates to a self-lubricating bearing, in particular to a self-lubricating bearing with a continuous self-lubricating surface. Background technique [0002] For some self-lubricating bearings used in high-temperature environments, the following structures are currently used: multiple holes are opened on the steel base of the self-lubricating bearing, solid self-lubricating materials are poured into the holes, and adhesives are used to allow the The self-lubricating material is firmly bonded to the steel base. During the rotation of the bearing with this structure, the self-lubricating material will spread a layer of lubricating film on the friction surface to achieve the purpose of self-lubricating. However, when the rotating speed of the working shaft is low, since this self-lubricating material is solid and has no fluidity, it often cannot form a continuous lubricating picture, which affects the lubrication effect, causing the metal pa...
