Abstract

The invention provides a method for changing friction coefficient between interfaces and a device thereof. According to the method for changing friction coefficient between interfaces, an electric field is applied between two interfaces containing a lubricant. The lubricant contains a polar additive capable of changing friction coefficient of the lubricant when voltage of the electric field changes. By the method and the device, friction coefficient between interfaces can be changed. For example, friction coefficient can be raised or reduced. Friction effect is changed, reliability of equipment is enhanced, and lubricating property requirement of equipment under different working conditions is met.

Description

technical field [0001] The invention relates to a method and a device for changing the friction coefficient between interfaces, in particular to a method and a device suitable for changing the friction coefficient 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. The same electromechanical system may work under various working conditions. For example, only the transmission oil of a car needs to meet different road conditions and operating conditions during the operation of the car. Therefore, the diversification of lubricity of lubricants is an issue of interest to those skilled in the art. [0003] Coefficient of friction generally refers to a measure of how easily one material slides over another. The coefficient of friction applies to a pair of materials rather than simply to an object itself. A common way to change the coefficient ...
