Elastohydrodynamic lubrication
| Oil glossary |
In rolling element bearings, the elastic deformation of the bearing (flattening) as it rolls, under load, in the bearing race. this momentary flattening improves the hydrodynamic lubrication properties by converting point or line contact to surface-to-surface contact.

Elastohydrodynamic (ehl or ehd) lubrication, английский
A thin-film form of lubrication in which an elastic deformation occurs between two non-conforming
Lubricate, английский
- Lubricado/a
- Lubricar
Lubricated, английский
Lubricateur, французский
Lubricating, английский
Lubricating jelly, английский
A jelly used to make a surface slippery

Lubricating system, английский

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).

Lubrication survey, английский
An examination of potential lubrication-related food-contamination risks in a facility, generally conducted as part of an haccp (hazard analysis and critical control point) plan.
Lubrication systems, английский
Lubrication zone (lube systems), английский
Part of a larger lubrication system that can be isolated from other portions of the system for control purposes; generally contains some type of inlet valve, a master divider, secondary dividers and distribution tubing network to lubrication points.
Lubrication, flange, английский
One of the critical areas of wear on railways occurs at the point of contact between wheel flange and rail at curves. this wear reduces the flange profile and, if allowed to develop, can cause derailment. it also damages the inside edge of the rail head. the wear can be reduced by lubrication of the area. the lubricators may consist of flange-actuated track mounted lubricators at the entrance to curves or trains may be fitted with on-board flange lubrication. the paris metro, for example, used a train-mounted lubricator which was actuated by links on the bogie which detected the change in angle as it turned onto a curve and injected a small amount of oil onto the wheel. the risk with flange lubrication is over application. this will leave lubricant on the wheel tread or rail head and result in skidding during braking. one such celebrated occasion occurred on london`s victoria line some years ago which resulted in 35% of the trains being unserviceable due to flatted wheels damaged by skidding.
Lubricator, английский
- A device which adds controlled or metered amounts of lubricant into a pneumatic system.
- The oil or similar material applied to the bearings of machinery to obviate friction. also, special preparations of the same included in cartridges for rifled fire-arms, to prevent the fouling from the burnt powder adhering to the interior of the bore.
- Лубрикатор; маслёнка; маслораспылитель; тавотница
Lubricator type, английский
Deformation, немецкий
Flattening, английский
- Уплощение (паруса)
- Выравнивание; рихтовка; правка; раскатка; расплющивание ~ of the flood wave распластывание паводка
Hydrodynamic, английский
- Гидродинамический
- A shape designed to move efficiently through the water.
Properties, английский
- A dockable window that displays the properties that are set on the selected object. in most cases, the property values can be edited in the window.
- A ui element that users can click to display information about a selected object.

Electrical insulating oil, английский
A high-quality oxidation-resistant oil refined to give long service as a dielectric and coolant for electrical equipment, most commonly transformers. an insulating oil must resist the effects of elevated temperatures, electrical stress, and contact with air, which can lead to sludge formation and loss of insulation properties. it must be kept dry, as water is detrimental to dielectric strength – the minimum voltage required to produce an electric arc through an oil sample, as measured by test method astm d 877.
Dynamic seal, английский
A seal that moves due to axial or radial movement of the unit.
