Hydrodynamic lubrication
| Oil glossary |
- A system of lubrication in which the shape and relative motion of the sliding surfaces causes the formation of a fluid film having sufficient pressure to separate the surfaces.
- A type of lubrication effected solely by the pumping action developed by the sliding of one surface over another in contact with an oil. adhesion to the moving surface draws the oil into the high-pressure area between the surfaces, and viscosity retards the tendency to squeeze the oil out. if the pressure developed by this action is sufficient to completely separate the two surfaces, full-fluid-film lubrication is said to prevail.
- Often referred to as “full film lubricant”; a film of oil or other fluid completely separates moving components under load, thus maintaining low friction and eliminating wear.

Lubrication, английский
- 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.
- Смазка
- On no account should oil be used to lubricate pin-tumbler cylinders. graphite is the conventional lubricant for this mechanism.
- Смазка (действие)
- The act of injecting a fluid, normally bentonite and/or polymers, to reduce the skin friction and jacking forces on the jacking pipe during installation. the fluid fills the annular space.
- Means of reducing friction either around a pipe being jacked or a shaft being sunk into the ground.
- The control of friction and wear between two moving, touching surfaces by placing a friction-reducing substance between them.
- Control of friction and wear by the introduction of a friction reducing film between moving surfaces in contact. the film may be fluid, solid or plastic.
- Reduction of friction or wear between two load-bearing surfaces by the application of a lubricant; includes boundary lubrication (thin or interrupted fluid film, especially bearings where wear occurs); mixed film, where some liquid pools support the load; elastohydrodynamic (high-pressure loads increase the lubricant’s viscosity and load-carrying capacity, especially in gears); hydrodynamic (a thick fluid film lubrication, especially in journal bearings) and hydrostatic (external pump pressure used to form a thick fluid film, as in start-up of journal bearings).
