Method and device for changing lubricating performance between interfaces

Abstract

The invention provides a method and device for changing the lubricating performance between interfaces. According to the provided method, an electric field is applied on the space, which comprises a lubricant, between two interfaces; the lubricant comprises a polar additive, and the polar additive can change the lubricating performance of the lubricant when the voltage of the electric field changes. The provided method and device can change the lubricating performance between interfaces, and the wear, friction coefficient, and extreme pressure property can be increased or reduced. By reasonably changing the lubricating performance between interfaces, the reliability of equipment installation is improved, and the requirements of equipment on lubricating performance under different work conditions can be met.

Description

technical field [0001] The invention relates to a method and a device for changing the lubricating performance between interfaces, in particular to a method and a device suitable for changing the lubricating performance of the metal interface of a gearbox and a guide rail. Background technique [0002] With the development of science and technology, various electromechanical systems are gradually upgraded. Lubricants with different lubricating properties are required for different electromechanical systems in the past, so that there are multiple lubricants in a complete system at the same time, such as only in automobiles. Engine oil, automotive gear oil, brake fluid, transmission fluid and automotive grease. The generalization of lubricants is a matter of interest to those skilled in the art. [0003] Since the 1950s, people have carried out a lot of research on the relationship between the electric field and the tribological behavior of materials, and tried to use an exte...
