Abstract

The invention discloses gear oil for assembly of new energy automobiles, and belongs to the technical field of gear oil. The gear oil comprises, by mass, 88-95% of base oil, 0.4-3.0% of antioxidants,0.4-1.8% of rust inhibitors, 2-4.2% of anti-wear agents, 0.001-0.05% of antifoaming agent, 0.1-1.5% of pour point depressants, 0.03-0.12% of oily agent and 1.2-2.2% of tackifiers. The gear oil has theadvantages that the gear oil does not contain sulfurized isobutylene, has no odor in the production process, and is neutral in itself, thereby not having corrosive effect on transmissions; the base oil, mostly vegetable oil, is economical and environmentally friendly, and the biodegradability can reach more than 95%; the viscosity of the oil is low, the flowability at a low temperature is high, normal lubrication can be ensured during start-up of a motor in winter, and rapid cooling can be guaranteed during high-speed operation.

Description

technical field [0001] The invention relates to the technical field of gear oil, in particular to a new energy vehicle assembly gear oil. Background technique [0002] Gear oil mainly refers to the lubricating oil of transmission and rear axle. Automotive gear oil is used in gear transmission mechanisms such as automotive steering gears, transmissions, and drive axles, mainly to lubricate gears and bearings, prevent wear and corrosion, and help gears dissipate heat. Due to the high surface pressure during gear transmission, gear oil plays an important role in the lubrication, anti-wear, cooling, heat dissipation, anti-corrosion and anti-rust, cleaning and reducing the impact and noise of the gear surface. [0003] The new energy vehicle assembly gear oil of the present invention is suitable for the transmission part of the new energy vehicle, and its function is mainly to cool the motor rapidly when the motor rotates at a high speed, so as to prevent the parts from being bu...
