Question

explain fully concept of lubrication

Answer 1

Lubrication Meaning. Lubrication is the control of friction and wear by the introduction of a friction-reducing film between moving surfaces in contact. The lubricant used can be a fluid, solid, or plastic substance. ... Lubricantscontaining oil have additives that enhance, add or suppress properties within the base oil

Hi There!
Here's your answer!

Lubrication

Lubrication is the process or technique of using a lubricant to reduce friction and/or 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[citation needed] or gases.

Fluid-lubricated systems are designed so that the applied load is partially or completely carried by hydrodynamic or hydrostaticpressure, which reduces solid body interactions (and consequently friction and wear). Depending on the degree of surface separation, different lubrication regimes can be distinguished.

Adequate lubrication allows smooth, continuous operation of machine elements, reduces the rate of wear, and prevents excessive stresses or seizures at bearings. When lubrication breaks down, components can rub destructively against each other, causing heat, local welding, destructive damage and failure.
