EHL (Elastohydrodynamic lubrication)

Elastohydrodynamic lubrication (EHL) is a scientific concept that describes how fluids behave between two surfaces in contact, like gears or bearings, under high pressure and speed. In EHL, the surfaces deform slightly due to the pressure, and this deformation, combined with the properties of the lubricant, creates a thin film of fluid that prevents direct contact between the surfaces. This reduces friction and wear, improving the efficiency and lifespan of machinery. EHL plays a critical role in many mechanical systems, ensuring smooth operation and reliability in various engineering applications.
