Abstract

The invention relates to a gear oil composition for a non-road transportation dump truck, which comprises the following raw materials in percentage by mass: 100 parts of blend base oil, 1-5 parts of sulfurized isobutylene (of which the sulfur content is 40%), 0.1-1.1 parts of ammonium salt of thiophosphoric acid (of which the sulfur content is 10% and the phosphorus content is 8.5%), 0.2-2.5 parts of sulfur-phosphorus dioctyl alkaline zinc salt (of which the sulfur content is 14% and the phosphorus content is 7.5), 0.2-1 part of di-tert-butyl-para-cresol, 0.2-1 part of auxiliary antioxidant, 0.02-1 part of dodecylene succinic acid and 0.05-1 part of glycol ester. The gear oil provided by the invention is superior to 85W / 90GL-5 gear oil in the aspects of physical and chemical indexes and service performance, has the advantages of favorable extreme-pressure abrasion resistance, high thermal oxidation stability, favorable corrosion resistance and favorable demulsibility, and satisfies the requirements for the performance of gear oil for a non-road transportation dump truck.

Description

technical field [0001] The invention belongs to the technical field of lubrication, and in particular relates to a gear oil composition for non-road transport dump trucks. Background technique [0002] In recent years, road transport dump trucks have been used in large-scale open-pit mining areas. Because of their small carrying capacity and poor stability, it is difficult to meet the performance requirements of dump trucks in mining areas, and they have been gradually eliminated. Non-highway transport dump truck, which increases the width of the vehicle, takes into account the requirements of mining vehicles and the advantages of road dump trucks, and has greatly improved in terms of power, stability and carrying capacity compared with road transport vehicles. It has been widely used to meet the requirements of mine transportation conditions. However, due to the particularity of the working environment of non-road transport dump trucks—the dust is heavy and the vehicle is ...
