No.1009E 2012Automotive Technology Special Edition High Efficiency and Tribology in Rolling Bearings

Category TECHNICAL REPORT
Author H. MATSUYAMA
Material Engineering R&D Dept., Research & Development Center, Research & Development Headquarters
Abstract Rolling bearings widely used to support rotating shafts in various industrial machineries are based on tribology. Tribology is the science and technology of interacting surfaces in relative motion and of related subjects and practices and is an engineering technology that deals with friction, wear, lubrication, etc. This report explains the lubrication theory of rolling bearings with a focus on elastohydrodynamic lubrication (EHL) and gives examples of applying tribology to the high efficiency technology for tapered roller bearings that are used in a variety of automotive applications.
