A kind of heavy-duty open gear lubricating grease and preparation method thereof

Abstract

The invention discloses a heavy-duty open gear lubricating grease and a preparation method thereof. The heavy-duty open gear lubricating grease comprises the following components in terms of the weight percentage of the lubricating grease: 57-80% of base oil, and a composite aluminum thickener 3-6%, extreme pressure anti-wear agent 3-7%, oily agent 2-5%, solid additive 5-10%, rust inhibitor 0.5-1%, tackifier 6-13%, antioxidant 0.5-1.0 %. On the basis of the existing open gear grease, it provides a kind of grease with good adhesion and extreme pressure and anti-wear performance to solve the problems of high power energy consumption and different levels of environmental protection restricted substances in existing products, and at the same time it can It is a heavy-duty open gear grease that fully meets the EU RoHS2.0 restricted substance requirements, significantly reduces frictional resistance, and saves power consumption, so as to meet the requirements of modern industrial development for grease.

Description

technical field [0001] The present invention relates to a kind of lubricating grease, especially a kind of lubricating grease used in heavy load open gear transmission system. Background technique [0002] Open gear is the most common power transmission method in the manufacturing industry. It is widely used in large-scale equipment in industries such as electric power, cement, mining, automobile manufacturing, steel, chemical industry, and papermaking, such as: rotary kiln, tube mill, sintering kiln, rod mill machine, coal mill, dryer, granulator, drum pulper, drying furnace, etc. The load of large open gear transmission is relatively large, and its effective and safe operation not only depends on the design of gears and the materials used in gears, but also depends more on correct assembly, efficient lubrication maintenance and high-quality lubricants. According to industry statistics: In addition to improper design, manufacture, installation, operation and maintenance, n...
