Abstract
The invention discloses an oil-free lubricating bearing and a preparation technology thereof. The oil-free lubricating bearing is prepared from the following components in parts by mass: 5 to 10 partsof zirconiumoxide, 15 to 30 parts of graphite, 5 to 12 parts of molybdenum disulfide, 10 to 15 parts of boroncarbide, 5 to 10 parts of zincstearate, 3 to 5 parts of titanium, 3 to 5 parts of nickel, 4 to 8 parts of copper, 3 to 6 parts of dysprosium and 10 to 20 parts of iron. A preparation method disclosed by the invention is simple and easy to operate; the surface of the prepared bearing hashigh rigidity; a lubricating effect of the dysprosium at room temperature is utilized so as to ensure that the lubricating performance of the bearing can be ensured under a high-temperature conditionin a utilization process of the bearing, and furthermore, the safety of the bearing is ensured; a bearing material can effectively react with a polymer to generate a new friction substance and a relatively low friction coefficient is realized. The bearing not only has the advantages of high strength, high rigidity and abrasion resistance, but also has relatively good toughness; the bearing is thehigh-strength and stable-performance oil-free lubricating bearing applicable to the industrial fields including aerospace, navigation, nuclear industry and the like.
Description
technical field [0001] The invention relates to the technical field of bearing processing, in particular to an oil-free lubricating bearing and a preparation process thereof. Background technique [0002] Due to the limitations of traditional lubrication methods for bearings, self-lubrication technology for bearings has become a future trend. The metal-based inlaid solid self-lubricating bearing material can realize self-lubrication without refueling or refueling at long intervals, and can realize self-lubrication under harsh working conditions such as high temperature, low temperature, pollution, corrosion, fresh water or sea water, vacuum, radiation, etc. And it has incomparable advantages such as low friction coefficient, small wear and long life. Among them, the solid lubricating material can effectively reduce friction and wear through the lubricating transfer film produced by friction with the pair friction parts, successfully breaking through the limitations of tradi...
