Problems solved by technology

When the rolling bearing is working, the bearing heats up and wears due to sliding friction. Especially under high-temperature operating conditions, the action of inertial centrifugal force intensifies the friction, wear and heat. Low efficiency and short life
The above reasons are mainly due to the shortage of alloy materials used to manufacture bearings, and often need to add lubricating oil to meet the requirements of high-speed operation. In addition, the anti-oxidation power is not enough, it is easy to rust and corrode, and the service life is greatly reduced, which needs to be improved.

Abstract

The invention discloses an alloy material for manufacturing bearing inner rings. The alloy material is characterized by comprising the following components in percentage by weight: 30 to 50% of iron, 6 to 8% of manganese, 10 to 30% of aluminum, 1 to 8% of lithium, 3 to 10% of zinc, 1 to 5% of molybdenum, 1 to 5% of zirconium, 0.3% to 2% of carbon, and 10 to 20% of nano graphite. The alloy material can improve the antioxidant performance and anticorrosion performance of bearing, can achieve a self-lubricating effect, reduces the addition frequency of lubricant, and prolongs the service life of bearing.

Description

technical field [0001] The invention relates to an alloy material used for manufacturing the inner ring of a bearing. Background technique [0002] Rolling bearings are widely used important mechanical basic parts, and are widely used in various fields of national economy and national defense. When the rolling bearing is working, the bearing heats up and wears due to sliding friction. Especially under high-temperature operating conditions, the action of inertial centrifugal force intensifies the friction, wear and heat. Low efficiency and short life. The above reasons are mainly due to the shortage of alloy materials used to manufacture bearings, often need to add lubricating oil to meet the requirements of high-speed operation, and in addition, the anti-oxidation power is not enough, easy to rust and corrode, and the service life is greatly reduced, which needs to be improved. Contents of the invention [0003] The purpose of the present invention is to provide an alloy...
