Problems solved by technology

The working conditions of hyperbolic gear transmission are more severe, and the requirements for the performance of automotive gear oil are higher. If there is no suitable gear oil, the normal lubrication of the gears cannot be guaranteed, which will easily lead to early wear and abrasion of the gears, and even cause major damage. Vehicle and Personal Accidents

Abstract

The invention discloses an improved gear oil composition which is prepared from the following raw materials in parts by weight: 36-44 parts of 38# cylinder oil, 0.5-0.9 part of BHT (butylated hydroxytoluene) antioxidant, 3-6 parts of di-n-butyl phosphite, 2-8 parts of sulfur-phosphorous butyl octanol zinc salt, 0.6-0.9 part of sodium petroleum sulfonate, 3-8 parts of chlorinated paraffin wax, 9-15 parts of dithiodipropionate, 5-15 parts of p-phenylenediamine, 5-15 parts of dibenzyl disulfur, 4-12 parts of polydimethylsiloxane, 9-16 parts of benzotriazole, 15-25 parts of synthetic oil and 3-12 parts of graphite. The improved gear oil composition can achieve maximum nonseizure load for lubrication and reduce the sintering load and comprehensive abrasion by reducing the abrasion loss of the automobile gear, and has the advantages of excellent abrasion resistance, excellent corrosion resistance and excellent rust resistance.

Description

technical field [0001] The invention relates to the technical field of gear oil, in particular to an improved gear oil composition. Background technique [0002] Gear oil is one of the three major varieties of lubricating oil, which plays a vital role in the power transmission of various equipment. Due to the heavy load of gears during work, good extreme pressure and anti-wear properties are one of the most important characteristics of gear oils. Especially with the development of machinery towards high-load, high-temperature, and high-pressure operations, for Heavy-duty industrial gear oils are in increasing demand. [0003] Automotive gear oil is used for the lubrication of gears, bearings and other parts of mechanical transmissions, drive axles and steering gears, and plays the role of lubrication, cooling, rust prevention and buffering. Due to the complex working conditions of automotive gears, high contact pressure, fast peripheral speed, high sliding speed, and high ...
