Abstract

The invention discloses a gearbox speed changer lubricant composition as well as a preparation method and application thereof. The lubricant composition comprises the following components in percentage by weight: 30%-60% of ultralow-viscosity poly-alpha-olefin PAO, 0.01%-0.5% of modified graphene, 2%-10% of a gearbox composite additive, 0.03%-0.06% of an anti-foaming agent and the balance being base oil. The base oil comprises mineral oil and / or a mixture of poly-alpha-olefin PAO and synthetic ester; and the modified graphene is a modifier of single-layer graphene oxide and / or single-layer fluorinated graphene. The lubricant composition is suitable for lubrication of gearbox speed changers of electric vehicles, hybrid electric vehicles and fuel locomotives.

Description

technical field [0001] The invention relates to a lubricant composition, in particular to a gearbox transmission lubricant composition. Background technique [0002] Gearbox transmission is an important part of the power transmission system. Its working efficiency and service life not only depend on the working conditions, load, material characteristics and manufacturing quality, but also depend on the lubrication protection performance of the lubricant. [0003] The performance of the lubricant usually has a direct impact on the working efficiency and service life of the key components of the gearbox transmission, such as gears, synchronizers and multi-plate clutches. Typically, lubricants form a thick film of oil on the internal surfaces of the transmission to reduce friction and wear between the moving parts. If the lubricating performance of the lubricant is poor, it will not only cause pitting, gray spots, gluing and other wear on the surface of the gear, but also incr...
