  2. Automatic lubrication system - Wikipedia

    en.wikipedia.org/wiki/Automatic_lubrication_system

    Automatic lubrication systems (ALS), also known as centralized lubrication systems (CLS), are mechanical devices designed to dispense precise quantities of lubricant to multiple points within machinery during operation. While typically fully automated, some systems may require manual activation via pumps or buttons and still fall under the ...

  3. Total-loss oiling system - Wikipedia

    en.wikipedia.org/wiki/Total-loss_oiling_system

    A needle valve adjusts the rate of flow, which may be seen as drops passing through the window beneath the glass reservoir. A total-loss oiling system is an engine lubrication system whereby oil is introduced into the engine and then either burned or ejected overboard. Now rare in four-stroke engines, total loss oiling is still used in many two ...

  4. Self-lubricating chain - Wikipedia

    en.wikipedia.org/wiki/Self-lubricating_chain

    Self-lubricating chains, also referred to as lube-free chains, are commonly found in both roller chain ( ANSI Standards, British Standards, and DIN Standards) and conveyor chain varieties, with specialty self-lubricating chains also available. These chains utilize a bush made of an oil-impregnated sintered metal or plastic to provide continuous ...

  5. Automatic lubricator - Wikipedia

    en.wikipedia.org/wiki/Automatic_lubricator

    The smaller one to the right is a ยง syphonic lubricator. An automatic lubricator is a device fitted to a steam engine to supply lubricating oil to the cylinders and, sometimes, the bearings and axle box mountings as well. [ 1] There are various types of automatic lubricator, which include various designs of displacement, hydrostatic and ...

  6. Watt's linkage - Wikipedia

    en.wikipedia.org/wiki/Watt's_linkage

    Description. Watt's linkage consists of three bars bolted together in a chain. The chain of bars consists of two end bars and a middle bar. The middle bar is bolted at each of its ends to one of the ends of each outer bar. The two outer bars are of equal length, and are longer than the middle bar. The three bars can pivot around the two bolts.

  7. Lubrication theory - Wikipedia

    en.wikipedia.org/wiki/Lubrication_theory

    Lubrication theory. A thin layer of liquid mixed with particles flowing down an inclined plane. In fluid dynamics, lubrication theory describes the flow of fluids ( liquids or gases) in a geometry in which one dimension is significantly smaller than the others. An example is the flow above air hockey tables, where the thickness of the air layer ...

  8. Lubrication - Wikipedia

    en.wikipedia.org/wiki/Lubrication

    Lubrication is the process or technique of using a lubricant to reduce friction and wear and tear in a contact between two surfaces. The study of lubrication is a discipline in the field of tribology . Lubrication mechanisms such as fluid-lubricated systems are designed so that the applied load is partially or completely carried by hydrodynamic ...

  9. Galileo (satellite navigation) - Wikipedia

    en.wikipedia.org/wiki/Galileo_(satellite_navigation)

    Galileo launch on a Soyuz rocket on 21 October 2011. The first two Galileo In-Orbit Validation satellites were launched by Soyuz ST-B flown from Centre Spatial Guyanais on 21 October 2011, [ 63] and the remaining two on 12 October 2012. [ 64] As of 2017, the satellites are fully useful for precise positioning and geodesy with a limited ...
