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 lubricating oil, comprising the following substances by weight: 10-20 parts of chlorinated paraffin, 3-11 parts of sodium citrate, 5-25 parts of oleic acid, 1-5 parts of acetophenone, 1-4 parts of sorbitan monooleate, 2-11 parts of pentane, 3-7 parts of dioxane, 0.1-0.5 parts of calcium dialkylbenzene sulfonate, 0.01-1 part of phosphate ester and ammonium salt derivatives thereof, 0.1-0.7 parts of imidazoline, 1-3 parts of methyl silicone oil, and 75-85 parts of polyaleneglycol. The beneficial effects reside in that: the lubricating oil has advantages of excellent viscosity temperature performance, high viscosity index, low condensation point, high flash point and high water capacity.

Description

technical field [0001] The invention relates to a lubricating oil for gears. 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 emulsification ...
