Types of Lubrication Boundary, Hydrostatic, and
Lubrication reduces friction between the moving surfaces or rolling pairs. Some of the various types include hydrodynamic, hydrostatic, boundary and extreme pressure lubrication. The lubricant also act as a coolant carrying heat away from the sliding surfaces so it is necessary for all the moving parts in machinery or engine operation.
Lubrication is the process or technique of using a lubricant to reduce friction and wear in a contact between two surfaces. The study of lubrication is a discipline in the field of tribology. Lubricants can be solids (such as Molybdenum disulfide MoS2), solid/liquid dispersions (such as grease), liquids (such as oil or water), liquid-liquid dispersions or gases. Fluid-lubricated systems are designed so that the applied load is partially or completely carried by hydro

Elastohydrodynamic Lubrication (EHL): Theory and
Definition of Elastohydrodynamic Lubrication (EHL) Elastohydrodynamic Lubrication or EHL is a lubrication regime (a type of hydrodynamic lubrication (HL)) in which significant elastic deformation of the surfaces takes place and it considerably alters the shape and thickness of the lubricant film in the contact. The term underlies the importance of the elastic deflection of the bodies
Hydrodynamic lubrication is an excellent method of lubrication since it is possible to achieve coefficients of friction as low as 0.001 (m=0.001), and there is no wear between the moving parts. However because the lubricant is heated by the frictional force and since viscosity is temperature dependent, additives to decrease the viscosity's
