Lubrication is something like any kind of material which can lubricate in between the metal surface, Either that surface can directly come into the contact or maybe there is a lubrication which will act in between the two mating surfaces.
Definition- Lubrication is the process or technique employed to reduce friction between
surfaces in proximity and moving relative to each other, by interposing a substance called a lubricant in between them.
* This is mainly intended to minimize the wear
of one or both of the surfaces.
*When lubrication breaks down, components can
rub destructively against each other, causing heat, local welding, destructive
damage and failure.
The objective of Lubrication :
Lubrication is done to reduce
- Wear and tear of surfaces.
- Maintenance cost.
- The heat from the bearing.
- Unsmooth relative motion
- Expansion of metal due to frictional heat.
- Power loss
