Abstract

The invention discloses an oil-free bearing with high wear resistance and high heat resistance, and a preparation method thereof. The oil-free bearing with high wear resistance and high heat resistance is prepared from, by mass, 10-20 parts of ferroferric oxide, 1-6 parts of graphite, 2-4 parts of silicon dioxide, 3-6 parts of wolframite, 3-6 parts of aluminum oxide, 1-1.2 parts of hexagonal boronnitride, 2-2.2 parts of molybdenum disulfide, 3-6 parts of copper oxide, 2-4 parts of a high-temperature reinforcing agent, 2-2.8 parts of a wear-resistant reinforcing agent and 1.2-1.6 parts of a toughening agent. The novel oil-free bearing has the advantages of self-lubricating property, no addition of lubricating oil, avoiding of bearing powder, falling off due to high-speed friction, from being adhered to the bearing, good heat conductivity, high strength, creep resistance, high temperature resistance, easiness in heat conduction, and long service life.

Description

technical field [0001] The invention relates to the technical field of oil-free bearing preparation, in particular to an oil-free bearing with high wear resistance and high heat resistance and a preparation method thereof. Background technique [0002] Oil-free bearing is a novel lubricating bearing with the characteristics of both metal bearings and oil-free lubricating bearings. The metal matrix bears the load, and the specially formulated solid lubricating material acts as a lubricator. It has the characteristics of high bearing capacity, impact resistance, high temperature resistance, and strong self-lubricating ability. It is especially suitable for occasions where it is difficult to lubricate and form an oil film such as heavy load, low speed, reciprocating or swinging, and is not afraid of water flushing and other acid corrosion. and scour. [0003] However, oil-free bearings are prone to residues under high temperature and high friction conditions, which will affect...
