Transmission oils. Purpose and function
Transmission oils are intended for use in friction units of transmission units of cars and trucks, buses, tractors, locomotives, road-building and other machines, as well as in various gearboxes of industrial equipment. If your car does not need any more oil, then scrap my cars north york.
Transmission oils are a mixture of base oils and various functional additives. Mineral, semi-synthetic or synthetic oils are used as base components.
Gear oils are suitable for high sliding speeds, pressures and a wide temperature range. Their starting properties and long-term performance must be provided in the temperature range from -60 to +150 ° C, so they have rather strict requirements.
The main functions of gear oils:
protection of friction surfaces from wear, seizure and other damage;
Minimizing frictional energy losses;
Reduction of heat removal from friction surfaces;
Tooth gear noise and vibration reduction, reduction of shock loads;
oils should not be toxic.
Lubricating oils should have certain characteristics to ensure reliable and long-lasting operation of transmission units:
have sufficient anti-seize, anti-wear and anti-pitting properties;
have high antioxidative stability;
have good viscosity-temperature properties;
have no corrosive effect on transmission parts;
have good protective properties at contact with water;
be sufficiently compatible with rubber seals;
Have good anti-foam properties;
have high physical stability in conditions of long-term storage.
All these properties of gear oil can be provided by introducing appropriate functional additives into the base oil composition.
