Abstract

The invention discloses an open gear lubricating oil, which is characterized by the following: adopting synthesized oil as basic oil; making polyplant oil as thickener; adding auxiliary thickener, extreme-pressure agent, antirust agent and anti-oxidant; possessing excellent stickiness and low-temperature fluidity.

Description

technical field [0001] The invention relates to a lubricating oil, specifically a lubricating oil for open gears. The base oil is mainly synthetic oil, and the tackifier is mainly polymerized vegetable oil. Background technique [0002] There are many open gear transmissions in mining and metallurgical enterprises, such as the open gears of the lifting, pushing and turning parts of the imported large 295B and 395B electric shovels used in mining plants, the open gears of large ball mills in mineral processing plants, and the mixing Machine open gears and rollers, etc. Its working characteristics are harsh conditions such as dust and impurities, impact load, large temperature difference, and rain and snow erosion. The lubrication method is mostly realized by spraying or pumping, and there are also manual brushing. The requirements for lubricating oil are high viscosity, good viscosity, no oil rejection, thick oil film, high extreme pressure and wear resistance, good rust re...
