Abstract

The invention discloses an eccentric shaft sleeve which comprises the following components with content in percentage by weight: 60%-75% of copper, 2.5%-8% of manganese, 2.5%-5% of iron, 3%-5% of magnesium, 1%-2% of nickel, 5%-12% of chromium, 0.3%-1% of molybdenum, 1.5%-3% of nano-graphite, 0.5%-1% of molybdenum disulfide and 0.3%-2% of polytetrafluoroethylene. The eccentric shaft sleeve disclosed by the invention is greatly enhanced in self strength, mechanical strength and abrasion-resistant property and has lubricating effect.

Description

[0001] technical field [0002] [0003] The invention relates to an eccentric shaft sleeve and a processing and production process. [0004] Background technique [0005] [0006] At present, the eccentric bearings on the market have deficiencies in structure, insufficient strength, and are prone to fatigue and damage. In addition, in the actual installation and use process, a large amount of lubricating oil needs to be added, which increases the cost and is not conducive to long-term development. [0007] Contents of the invention [0008] [0009] One of the purposes of the present invention is to provide an eccentric bushing that improves its own strength, mechanical strength and wear resistance, and at the same time has a lubricating effect. [0010] To achieve the above object, the technical solution of the present invention is [0011] The eccentric shaft sleeve is characterized in that it includes the following components in terms of mass ratio: [0012]...
