Problems solved by technology

[0003] Due to objective factors such as the vibration of the unit and the weight of the equipment itself, the load on the bearing is relatively large, which may easily cause the rupture of the lubricating film, resulting in increased friction, increased temperature, and even damage to the bearing.

Abstract

The self-lubricating bearing comprises a bearing inner ring, the bearing inner ring is provided with a micro-texture group, the micro-texture group comprises a plurality of micro-textures which are evenly distributed at certain intervals, each micro-texture comprises a placoid-scale-shaped groove and a storage hole, and the storage holes are communicated with the grooves. The placoid-scale-shaped groove comprises a first face, a second face and a third face, the top of the first face, the top of the second face and the top of the third face are sequentially connected to form a first triangular opening, the bottom of the first face, the bottom of the second face and the bottom of the third face are sequentially connected to form a second triangular opening, and the storage hole is formed in the bottom of the second triangular opening. The placoid-scale-shaped groove and the storage hole are used for filling a solid self-lubricating composite material and storing chippings generated in the friction process, the invention aims to provide the self-lubricating bearing based on the bionic microstructure and the self-lubricating composite material filling method, the coverage degree and adhesiveness of the self-lubricating bearing on the friction surface can be remarkably improved, and ultralow lubrication is achieved.

Description

technical field [0001] The invention relates to the technical field of self-lubricating bearings, in particular to a self-lubricating bearing based on bionic micro-texture and a method for filling self-lubricating composite materials. Background technique [0002] With the rapid development of modern high-end technology, the working conditions of rotating parts are becoming more and more extreme, and traditional liquid-lubricated and self-lubricating bearing products are difficult to meet the requirements of new working conditions. Taking the working condition of the double-fed wind turbine bearing as an example, the speed of the generator is 1200r / min during normal operation, and the shaft and the grease will produce high-speed relative motion, causing the bearing to heat up. [0003] Due to objective factors such as the vibration of the unit and the weight of the equipment itself, the load of the bearing is large, which is easy to cause the rupture of the lubricating film,...
