Description

Distillate type hyperbolic gear oil Distillate type hyperbolic gear oil

Technical field

 The invention relates to the field of automobile parts, in particular to a fractional hyperbolic gear oil.

Background technique

Automotive gear oils are used for lubrication of gears, bearings and other parts of mechanical transmissions, drive axles and steering gears, for lubrication, cooling, rust and cushioning. Due to the complicated working conditions of the automobile gear, the contact pressure is large, the circumferential speed is fast, the sliding speed is high, and the oil temperature is high, the requirement for the gear oil is high. The working conditions of the hyperbolic gear transmission are more demanding, and the performance requirements of the automobile gear oil are higher. If there is no suitable gear oil, the normal lubrication of the gear cannot be guaranteed, which may lead to early wear and abrasion of the gear, and even cause a large Vehicle and personal accidents. Therefore, in order to maintain the normal transmission of the power of the car engine, the quality of the car gear oil is very important.

Summary of the invention

The technical problem to be solved by the present invention is to provide a fractional hyperbolic gear oil which reduces the wear amount of an automobile gear, achieves the maximum no-biting load of lubrication, reduces the sintering load and comprehensive wear, and prolongs the life of the engine.

In order to solve the above technical problem, the technical solution of the present invention is: a fractional hyperbolic gear oil, which is innovative in that the ratio by weight is made up of the following components:

Neopentyl polyol ester 53-82 parts;

BHT antioxidant 0.3-1.4 parts;

Borate ester 2-3 parts;

Di-n-butyl phosphite 0.1-1.0 parts;

3-7 parts of zinc thiophosphonate;

Dihydrocarbyl pentasulfide 2-3 parts;

Sodium petroleum sulfonate 0.5-1.0 parts;

4-13 parts of chlorinated paraffin;

Phosphorus Star 2-3 servings;

Methyl silicone oil 2-5 parts;

Alkylnaphthalene 0.5-1.0 parts.

Further, the borate ester contains boron, sulfur and nitrogen elements.

The invention has the advantages that the invention has excellent extreme pressure anti-wear performance, high carrying capacity, can be configured with heavy-duty vehicle gear oil, and can also be used for heavy-duty and medium-duty industrial gear oils.

The formula of the invention is scientific and reasonable, so that the lubrication of the gear steel ball does not cause the highest load of the bite, and the complete oil film can be maintained between the friction surfaces under the load; the minimum load of the gear steel ball is sintered, and the limit working ability of the lubrication is achieved; The mathematical average of several times of the comprehensive wear value of the gear steel ball to achieve the average anti-wear performance of the whole process from low load to sintering load, the operating temperature range of the automobile gear oil of the invention is also wide, and the automobile gear is maximally satisfied. Lubricate and extend its life.
