Abstract

The invention discloses a formulation for gear oil of an automobile transmission and relates to the field of automobile lubrication oil. The formulation for the gear oil of the automobile transmission comprises, by mass, 76-80% of hydrogenated basic oil, 2.6-4.3% of sodium sulfite, 2.6-4.7% of dodecylbenzene sodium carbonate, 0.7-1.6% of butylated hydroxytoluene, 1.9-2.6% of potassium borate, 5.7-8.2% of dimethione and 4.8-6.1% of oleamide. Compared with common gear oil, the gear oil has the better extreme pressure anti-wear property and higher oxidation resistance.

Description

technical field [0001] The invention relates to the field of automobile lubricating oil, more specifically, the invention relates to a formula of gear oil for automobile transmission. Background technique [0002] Gear oil is an important lubricating oil prepared by adding petroleum lubricating oil base oil or synthetic lubricating oil, adding extreme pressure antiwear agent and oiliness agent. Gear oil for automobile gearboxes is mainly used in gear transmissions in automobile gearboxes to prevent tooth surface wear, abrasion, sintering, etc., prolong its service life, and improve transmission power efficiency. At present, most of the common automotive gear oils are not good enough in anti-oxidation and anti-rust performance, and the extreme pressure and anti-wear properties of gear oils are poor. Contents of the invention [0003] The problem to be solved by the present invention is to provide a gear oil formula for automobile transmission with good extreme pressure and...
