Lubrication, flange
| Глоссарий в железнодорожной технике |
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.

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).
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

Faregate, английский
Part of an automatic fare collection (afc) system where the device is placed at station entrances and exits to regulate access by reading a ticket inserted by the passenger and restricting access if the ticket is not correct. various types are in use around the world to prevent passenger fraud and to permit the handling of large numbers of passengers with a minimum of staff. modern systems are now adopting non-contact electronic card readers like the hong kong "octopus" and london "oyster" cards
