What type of mechanism is eccentric?
What type of mechanism is eccentric?
eccentric-and-rod mechanism, arrangement of mechanical parts used to obtain a reciprocating straight-line motion from a rotating shaft; it serves the same purpose as a slider-crank mechanism and is particularly useful when the required stroke of the reciprocating motion is small in comparison with the dimensions of the …
Where is an eccentric cam used?
It is used most often in steam engines, and used to convert rotary motion into linear reciprocating motion to drive a sliding valve or pump ram. To do so, an eccentric usually has a groove at its circumference closely fitted a circular collar (eccentric strap).
What is a eccentric wheel?
eccentricnoun. A disk or wheel with its axis off centre, giving a reciprocating motion.
What is an eccentric gear?
Also found in: Encyclopedia. (Mach.) The whole apparatus, strap, and other parts, by which the motion of an eccentric is transmitted, as in the steam engine. A cogwheel set to turn about an eccentric axis used to give variable rotation.
What is simple eccentric?
1 : a person who behaves in odd or unusual ways : an eccentric person. 2 : a mechanical device consisting of an eccentric (see eccentric entry 1 sense 2b) disk communicating its motion to a rod so as to produce reciprocating motion.
What is eccentricity in civil engineering?
The degree to which two forms fail to share a common center; for example, in a pipe or tube whose inside is off-center toth regard to the outside. In hollow extrusions: the difference between the maximum and minimum wall thickness at any single cross-section.
What is a pear cam used for?
Pear cams are called this as they have the shape of a pear. It remains stationary for half a turn then gently rises and falls. These are used to make carousel horses rise and fall.
