Abstract

The invention discloses a lubricant composition for whole-floating high-speed bearing. In the lubricant composition, 66.66% by mass of oil soluble polyether and 33.34% by mass of trimethylolpropane oleate are compounded to obtain composite basic oil, which is then matched with a plurality of composite additives. The lubricant composition includes the basic oil, an antioxidant, a metal deactivator, a friction improver, an anti-wear agent, an extreme pressure agent, an anti-oxidizing and anti-corrosion agent, an anti-foaming agent, a cooling accelerant, and an antirust agent. The lubricant composition has excellent viscosity-temperature character, heat conductivity, heat capacity and anti-oxidizing and anti-corrosion property, low friction coefficient, is vibration-attenuating and anti-creeping, has noise reduction and high-temperature oxidizing stability, is anti-wear, has compatibility with rubber, is anti-shear, can effectively control increase of viscosity of oil product and is free of zinc, and is suitable for motion pairs in various alloy.

Description

technical field [0001] The invention relates to a fully floating high-speed bearing lubricant composition, which belongs to the field of bearing lubricants. Background technique [0002] Full-floating bearings are mainly used in high-speed, torque-transmitting occasions without any reaction force and bending moment. The two gaps are filled with lubricating oil with a pressure of 0.25-0.4Mpa, so that the floating bearings can move freely in the oil film. The rotor shafts rotate in the same direction at a much faster speed than the rotor shaft. [0003] Turbochargers are widely used in a variety of engines. Due to the external high pressure, high pressure and high-speed operating conditions, their working conditions are very harsh, and the work requirements are relatively demanding, because the manufacturing materials (usually high-temperature resistant non-ferrous metal materials are used) ) and high processing technology, among which the most difficult to manufacture is the...
