Problems solved by technology

[0003] The development trend of today's automobile field is energy saving and environmental protection. Due to the continuous improvement of automobiles, the air resistance during driving is gradually reduced, and at the same time, the air flow through the outer surface of the gearbox and drive axle is also reduced, resulting in the heat dissipation performance of the vehicle. become worse, the friction heat is difficult to dissipate, and the working temperature of the rear axle and gearbox is greatly increased, which will lead to the oil oxidation of the gear oil and the acceleration of the aging of the seals
[0004] In addition, heavy-duty trucks in my country generally have severe overloading, and truck overload increases the transmission power of drive axle gears. However, while the transmission power increases, the geometric dimensions of drive axle gears do not change much, which will lead to tooth loss. The surface pressure increases and the temperature rises. If there is not enough oil film protection, dry friction will occur, and the instantaneous friction heat is enough to melt the slightly convex and uneven processing marks on the tooth surface, causing sintering and abrasion, so the load capacity of the gear oil is improved. Improving its heat resistance, thermal oxidation stability and compatibility with seals is an important issue to be solved urgently

Abstract

The invention discloses modified gear oil and a production method. The modified gear oil is prepared from the following raw materials: base oil, an oxidation and corrosion inhibitor, an antirusting agent, an extreme pressure antiwear additive, a metal passivator, a demulsifier, vegetable gum and a thickener. The modified gear oil disclosed by the invention has the beneficial effects that the modified gear oil is formed by compounding the high-quality base oil with a novel environment-friendly gear additive; all raw materials of the modified gear oil are organically combined together, so that the modified gear oil has enough extreme pressure antiwear property, good demulsibility and good rust and corrosion resistance. In addition, the modified gear oil disclosed by the invention has betterviscidity, improves the strength of an oil film and enhances the performance of gear oil; bearing capacity of the gear oil can be greatly improved, the influence of a traditional lead-containing formula on the health of an operation worker is avoided, the service life of an oil product can be greatly prolonged, the oil change frequency is reduced, and the cost of enterprises is reduced.

Description

technical field [0001] The invention relates to the technical field of gear oil, in particular to a modified gear oil and a production method thereof. Background technique [0002] Gear oil mainly refers to the lubricating oil of the transmission and the rear axle, which mainly lubricates the gears and bearings, prevents wear and corrosion, and helps the gears to dissipate heat. Due to the high surface pressure during gear transmission, gear oil plays an important role in the lubrication, anti-wear, cooling, heat dissipation, anti-corrosion and anti-rust, cleaning and reducing the impact and noise of the tooth surface. [0003] The development trend of today's automobile field is energy saving and environmental protection. Due to the continuous improvement of automobiles, the air resistance during driving is gradually reduced, and at the same time, the air flow through the outer surface of the gearbox and drive axle is also reduced, resulting in the heat dissipation performa...
