Abstract

The invention discloses a preparation method for lubricating grease used for an automobile bearing. The preparation method comprises the following steps: dividing base oil into three equal parts so asto respectively obtain a parts of base oil, b parts of base oil and c parts of base oil; dividing trimethylolpropane triisostearate into two equal parts so as to respectively obtain a parts of trimethylolpropane triisostearate and b parts of trimethylolpropane triisostearate; obtaining an intermediate 1; obtaining an intermediate 2; and sequentially mixing the intermediate 1, the intermediate 2 and c parts of base oil, and adding a grinding auxiliary agent and a thickening agent so as to obtain the lubricating grease used for the automobile bearing. The lubricating grease prepared by using the method provided by the invention can maintain the multiple effects of the lubricating grease, improves the use temperature and prolongs the service life, has long bearing operation life and good fretting wear resistance, and can have good thickening ability to base oil through lithium 12-hydroxystearate.

Description

technical field [0001] The invention belongs to the technical field of automobile bearings, in particular to a method for preparing lubricating grease for automobile bearings. Background technique [0002] Bearing is an important part of contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. With the development of industrial manufacturing, the requirements for bearings are getting higher and higher. The bearing materials are required to be environmentally friendly and safe without harmful components. The bearing materials have high strength. ability to corrode. Automobile bearings mainly refer to hub bearings. The main function of hub bearings is to bear weight and provide precise guidance for the rotation of the hub. It bears both axial load and radial load, and is a very important component. Grease: Thick, greasy semi-solid. It is used in the...
