Problems solved by technology

Although improving the demulsification performance can temporarily solve the impact of water ingress on gear oil, the additives in gear oil are often gradually reduced with the separation of water
The existence of a small amount of water is still easy to cause lubrication failure
Direct replacement of gear oil increases the cost of use of the enterprise

Abstract

The invention discloses a gear buffer lubricating oil. The lubricating oil is characterized by comprising the following materials, by weight, 3-10 parts of methyl silicone oil, 10-30 parts of chlorinated paraffin, 0.1-1.7 parts of sulfur phosphor butyl octyl primary alkyl zinc salt, 0.1-0.5 part of alkyl benzene sulfonic acid, 1-1.4 parts of alkyl benzene synthetic calcium sulfonate, 1-2.7 parts of sulfurized calcium alkyl phenolate, 0.1-0.9 part of antiwear agents, 0.5-2.5 parts of sulfur phosphor dioctyl primary alkyl zinc salt, 0.1-2 parts of petroleum ether, 1-3 parts of acetophenone, 0.5-3 parts of polyisobutylene succinimide and 70-90 parts of polyaleneglycol. The beneficial effects of the lubricating oil are that, the lubricating oil has excellent viscosity-temperature performance, high viscosity index, low condensation point, high flash point and high water compatibility.

Description

technical field [0001] The invention relates to a gear buffer lubricating oil. Background technique [0002] Gear oil is an important lubricating oil prepared mainly from mineral base oil or synthetic base oil, adding extreme pressure anti-wear agent and oily agent. It is used in various gear transmission devices to prevent tooth surface wear and abrasion , sintering, etc., to prolong its service life, improve the efficiency of power transmission, and reduce power loss. Gear oil should have good anti-wear, load resistance and suitable viscosity. In addition, it should also have good thermo-oxidative stability, anti-foaming properties, water separation performance and anti-rust performance. Even under high operating temperature and load, the synthetic gear oil can still ensure that the various parts of the transmission system are not worn. [0003] In industrial production, cooling water often leaks into the lubrication system due to poor sealing, resulting in emulsificatio...
