Think of reciprocating motion, and cams — those kings of kinematic linkages — may come to mind. For good reason: Cams have been the traditional gold standard for reciprocating motion since the dawn of ...

Rolling-ring drives are friction drives that convert the constant rotary motion of a plain shaft into a traversing action that moves an attached carriage. Used in positioning and reciprocating ...

A cam is a simple mechanism that converts rotary motion (movement that goes round in a circle) into linear motion (movement in a straight line). These mechanisms can be found in car engines, printing ...
