When the stroke of a mechanism needs to be calculated, first identify the ground level for the specified slider-crank mechanism. This ground level is the axis on which both the crank arm pivot-point and the slider pin are positioned. Draw the crank arm pivot point anywhere on this ground level.
Dimensioned drawing of a slider-crank (left) and its kinematic diagram (right). In mechanical engineering, a kinematic diagram or kinematic scheme (also called a joint map or skeleton diagram) illustrates the connectivity of links and joints of a mechanism or machine rather than the dimensions or shape of the parts. Often links are presented as ...

A slider-crank is a four-bar linkage that has a crank that rotates coupled to a slider that moves along a straight line.. This mechanism is composed of three important parts: The crank which is the rotating disc, the slider which slides inside the tube and the connecting rod which joins the parts together.
the crank-rocker, in which the input crank fully rotates and the output link rocks back and forth; the slider-crank, in which the input crank rotates and the output slide moves back and forth; drag-link mechanisms, in which the input crank fully rotates and drags the output crank in a fully rotational movement.
A quick-return mechanism is a subclass of a slider-crank linkage, with an offset crank. Quick return is a common feature of tools in which the action is performed in only one direction of the stroke, such as shapers and powered saws , because it allows less time to be spent on returning the tool to its initial position.
A crosshead as part of a reciprocating piston and slider-crank linkage mechanism. Cylindrical trunk guide Hudswell Clarke Nunlow; crosshead and two slide bars. In mechanical engineering, a crosshead [1] is a mechanical joint used as part of the slider-crank linkages of long stroke reciprocating engines (either internal combustion or steam) and reciprocating compressors [2] to eliminate ...
An in-line slider-crank has its slider positioned so the line of travel of the hinged joint of the slider passes through the base joint of the crank. This creates a symmetric slider movement back and forth as the crank rotates. Offset If the line of travel of the hinged joint of the slider does not pass through the base pivot of the crank, the ...
