Description
Linear cams move backwards and forwards in a reciprocating motion and the shape of the surface of the cam determines how far, and in what manner, the ‘follower’ moves in response.
Features and Applications
Most cams are design using a Displacement Diagram - essentially a graph which plots the cam movement against the follower movement. A linear cam can be imagined to be the shape of the graph cut from solid plate and then passed backwards and forwards beneath the follower.
Note: A simple wedge can be regarded as a basic form of linear cam - when driven into the end of a timber log, or used as an axe, the wedge transfers the vertical linear motion of the hammer into a horizontal force which spilts the wood.
