MoS 2, for example, is compounded in materials for sleeve bearings, elastomer O-rings, carbon brushes, etc. Solid lubricants are compounded in plastics to form a "self-lubricating" or "internally lubricated" thermoplastic composite. For example, PTFE particles compounded in the plastic form a PTFE film over the mating surface, resulting in a ...
A true grease consists of an oil or other fluid lubricant that is mixed with a thickener, typically a soap, to form a solid or semisolid. [1] Greases are usually shear-thinning or pseudo-plastic fluids, which means that the viscosity of the fluid is reduced under shear stress.
The Pennec Gaz'Aile 2 (English: a combination of Gazelle and wing) is a French amateur-built aircraft, designed by Serge Pennec of Locmaria-Plouzané and supplied in the form of plans for amateur construction.
A lubricant, aka lube, is a liquid, made of silicone, water, or oil, used during sexual activity to reduce friction by making the genital skin feel smoother, either solo or with a partner, says ...
Automatic lubrication (also called autolube or auto-lube) refers to a lubrication system on a two-stroke engine, in which the oil is automatically mixed with fuel and manual oil-fuel pre-mixing is not necessary. The oil is contained in a reservoir that connects to a small oil pump in the engine, which needs to be periodically refilled.
[2] In hydrostatic lubrication, external pressure is applied to the lubricant in the bearing to maintain the fluid lubricant film where it would otherwise be squeezed out. In hydrodynamic lubrication, the motion of the contacting surfaces, as well as the design of the bearing, pump lubricant around the bearing to maintain the lubricating film.
The oil droplets then pass through drillings to the bearings and thereby lubricate the moving parts. [3] Provided that the bearing is a ball bearing or a roller bearing, splash lubrication would usually be sufficient; however, plain bearings typically need a pressure feed to maintain the oil film, loss of which leads to overheating and seizure.
Since the 1980s, different types of two-stroke oil have been developed for specialized uses, such as outboard motor two-strokes, as well as the more standard auto lube (motorcycle) two-stroke oil. As a rule of thumb, it will be stated somewhere on the printed label of most containers of oil available commercially, that it is compatible with ...
