Lubrication is the science of reducing friction between two solid bodies in relativ e motion by interposing a lubricant between th eir rubbing surfaces. Elastohydrodynamic lubrication (EHL) is one of the forms of hydrodynamic lubrication based on the Reynolds equation while considering elastic deformation of solid surfaces and the viscosity‐pressure characteristics of a lubricant. Elastohydrodynamic lubrication is a development of hydrodynamic lubrication to take into account the elastic deflection of the surfaces in contact. If it’s true that you can’t run until you can walk, then neither can you make decisions about lubricants with-out knowing what viscosity means. About this page . Download as PDF. LUBRICATION •Pressure increase in the contact zone increases the viscosity •Trapped oil in the contact zone becomes a solid •Metal surfaces in the contact zone are “elastically” deformed •EHD friction (traction) from viscous shearing raises the contact zone temperatures •Examples: Rolling element bearings, gears, cams and followers, and traction devices. The rest of this article will outline those principles. Learning Objectives: – Define lubrication and describe the four forms of lubricants.
