Antifriction heat-conducting lubricating grease for motor bearings of pure electric vehicles

Abstract

The invention relates to an antifriction heat-conducting lubricating grease for motor bearings of pure electric vehicles. The lubricating grease is prepared from, by weight, 65-85% of base oil, 5-20%of thickener, 0.1-5% of antioxidant, 0.1-5% of rust and corrosion inhibitor, and 5-20% of modified graphite. The lubricating grease has the advantages of friction reduction, energy conservation, excellent heat conductivity and the like. The product meets the lubricating requirements of high-rotating-speed, high-temperature, high-load and extremely-low-temperature motor bearings of pure electric vehicles, significantly reduces the friction coefficient of motor bearings and saves electric energy; meanwhile, the product has great heat conductivity, so that the running temperature of bearings is greatly reduced, and accordingly the service life of bearings is prolonged.

Description

technical field [0001] The invention relates to the field of lubricants, in particular to a friction-reducing and heat-conducting lubricating grease for motor bearings of pure electric vehicles. Background technique [0002] A pure electric vehicle is a vehicle driven by a motor, and the main friction part of the motor is the motor bearing. With the development of pure electric vehicles in the direction of high speed, small size and heavy load, the thermal load that the motor bearing needs to bear is increasing, which leads to the long-term work of the bearing at high temperature, which eventually leads to a greatly shortened service life of the bearing. The maintenance of pure electric vehicles and usage costs continue to increase. [0003] However, the thermal load problem of pure electric vehicle motor bearings has not attracted the attention of pure electric vehicle manufacturers and lubricant material researchers. Lubricating grease meets the requirements of new type ...
