Problems solved by technology

No. 0 or No. 00 lubricating grease has also been used abroad and in China in recent years, but the viscosity is not enough, it is easy to throw oil, and it needs to be sprayed frequently, causing waste and pollution
Modified products often incorporate tackifiers, but have poor low temperature performance and poor pumping or spraying

Abstract

The invention discloses a solvent-diluted open-typed gear lubricant, which is characterized by the following: the basic oil is high-viscosity synthesized oil; the thickener is composite calcium sulfonate; the additive is auxiliary extreme-pressure agent, anti-oxidant and diluent; the lucribant possesses superior high-low temperature adaptability (low-temperature fluidity and high-temperature adhesive), which is not easy to volatilize under normal temperature.

Description

technical field [0001] The present invention relates to a lubricating grease, specifically a solvent-diluted open gear lubricating grease. Background technique [0002] There are many open gear transmissions in cement, mining and metallurgical enterprises, such as the open gears of the rotary kiln in the cement plant (extreme conditions such as high and low temperature, rain and snow erosion), the lifting, pushing and turning of the imported electric shovel used in the mining plant Open gears in parts (large temperature difference between day and night, rain and snow, dust, impact load), open gears of large ball mills in mineral processing plants (high line speed, easy to throw oil), open gears and idlers of mixers, etc. Its working characteristics are dust and impurities, impact load, large ambient temperature difference, rain and snow erosion, etc. The lubrication method is mostly realized by spraying or pumping. The requirements for lubricating oil are good viscosity, n...
