Most of the machine elements allow relative motion between its mating components while supporting the external load. In practice lubricant is fed into the contact zone of the mating components to reduce the friction. Due the convergent lubricant film in the contact zone, pressure develops and supports the load, which is known as hydrodynamic lubrication. As load is supported by the relatively small contact area, the pressure developed in the area is high to cause elastic deformation of the contact surfaces. The elastic deformation and film thickness are sometimes of the same order of magnitude. Hence the elastic deformation must be considered in the theory of hydrodynamic lubrication. Lubrication under such a condition is known as elastohydrodynamic lubrication (EHL). Lubricant in the conjunction alters the operational characteristics, like load carrying capacity, frictional loss and thereby, the life of the machine element.<\/p>\n\n\n\n
