Embodiment Construction
[0035] As a preferred embodiment, the composition of the heavy-duty open gear grease is as follows by weight percentage:
[0036]
[0037]
[0038] The invention is an energy-saving and environment-friendly heavy-duty open gear lubricating grease. The product is composed of high-viscosity refined mineral oil and high-viscosity synthetic oil thickened with a composite aluminum-based thickener, and multifunctional additives are added.
[0039] The base oil in the present invention is high-viscosity mineral oil and ultra-high-viscosity polyalphaolefin.
[0040] Thickening agent among the present invention is composite aluminum soap, is made by benzoic acid, fatty acid, aluminum isopropoxide trimer reaction, and benzoic acid is with C16 / C18 fatty acid together, with the aluminum in isopropoxide aluminum trimer The molar ratio is 1.9:1, and the molar ratio of benzoic acid to fatty acid is less than 1. .
[0041] The extreme pressure antiwear agent in the present invention i...

Abstract
The invention discloses a heavy-load open-type gear lubricating grease and a preparation method thereof. The lubricating grease comprises the following components in percentage by weight: 57 to 80% of basic oil, 3 to 6% of composite aluminum thickening agent, 3 to 7% of extreme pressure anti-wear additive, 2 to 5% of oiliness agent, 5 to 10% of solid additive, 0.5 to 1% of antirust agent, 6 to 13% of tackifier, and 0.5 to 1.0% of antioxidant. The provided lubricating grease is developed on the basis of the conventional open gear lubricating grease, is capable of solving the problems that the production of conventional lubricating grease consume too much energy and the conventional lubricating grease contains substances that can pollute the environment, has the advantages of good adhesive performance and extreme pressure anti-wear performance, and can fully meet the requirements on restricted substances RoHS 2.0 in Europe Union. The friction resistance and the energy consumption are prominently reduced by the provided lubricating grease, so that the lubricating grease can satisfy the requirements of modern industrial development.
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...
