Crank slider mechanisms with 0 and 1.25 eccentricity. A slider-crank linkage is a four-bar linkage with three revolute joints and one prismatic, or sliding, joint. The rotation of the drives the linear movement the slider, or the expansion of gases against a sliding in a cylinder can drive the rotation of the crank. There are two types of slider-cranks: in-line and offset. • In-line: 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 slider movement is not symmetric.

It moves faster in one direction than the other. This is called a quick-return mechanism. Spherical and spatial four-bar linkages [ ] If the linkage has four hinged joints with axes angled to intersect in a single point, then the links move on concentric spheres and the assembly is called a spherical four-bar linkage. The input-output equations of a spherical four-bar linkage can be applied to spatial four-bar linkages when the variables are replaced. Is a spatial four-bar linkage with hinged joints that have their axes angled in a particular way that makes the system movable. • Hartenberg, R.S.
