• 要約等: This paper reviews studies on friction control in elastohydrodynamic lubrication. Elastohydrodynamic lubrication is found in non-conformal contacts such as gears, rolling element bearings, and cam/tappet systems. High pressure up to several giga pascals is developed in a thin film formed in a small contact area, causing the piezoviscous effect and elastic deformations of bounding surfaces. High friction tends to be generated in elastohydrodynamic lubrication conditions because of the piezoviscous effect while for rolling element bearings and gears, friction should be reduced to improve the efficiency of machinery. Many researchers have investigated what the friction originates from in elastodydrodynamic lubrication conditions and how the friction can be controlled. Several technologies to reduce friction have been developed based on different points of view. Interesting findings for reducing friction are introduced in this paper.
