Lubrication
(Redirected from Lubricating)
Lubrication is a process or technique employed to reduce wear of one or both surfaces in close proximity, and moving relative to each another, by interposing a substance called lubricant between the surfaces to carry or to help carry the load (pressure generated) between the opposing surfaces. The interposed lubricant film can be a solid, (e.g. MoS2) a solid/liquid dispersion, a liquid, a liquid-liquid dispersion gasses.
Types of Lubrication[edit | edit source]
There are three distinct types of lubrication: boundary, mixed, and full-film.
Boundary Lubrication[edit | edit source]
In Boundary lubrication, the bodies come into closer contact at their asperities; the heat developed by the local pressures causes a condition which is part of the boundary lubrication state.
Mixed Lubrication[edit | edit source]
Mixed lubrication is a condition in which a lubricant film (oil film) does not completely separate the friction surfaces, but significantly affects the friction and wear rates.
Full-film Lubrication[edit | edit source]
In Full-film lubrication, the motion of the contacting surfaces, and the design of the bearing is used to pump lubricant around the bearing to maintain the lubricating film.
Lubrication Theory[edit | edit source]
Lubrication theory is the science of studying lubrication – its type, flow and the lubricants. It is a discipline that is guided by the principles of fluid dynamics and tribology.
Lubricants[edit | edit source]
Lubricants are typically used to separate moving parts in a system. This separation has the benefit of reducing friction and surface fatigue, together with reduced heat generation, operating noise and vibrations.
