MEX Mécanisme de Came et Suiveur
The Cam and Follower Mechanism, "MEX", designed by EDIBON, allows to demonstrate the operation of a cam-follower mechanism in a clear way.
The Cam and Follower Mechanism, "MEX", allows to study the cam-follower and eccentric-follower mechanisms. For that purpose, several plate cam models in different forms, one eccentric and several roller-shaped, flat-shaped, wedge-shaped and oscillating followers models are supplied.
A plate cam, also called disc cam, consists of a plate which rotates around an axis perpendicular to its plane. Its profile is designed to give a reciprocating or oscillating motion to a follower, which touches the edge of the cam.
The unit comprises five followers which depend on the geometrical characteristics of the edge in contact with the cam.
Two of them are roller-shaped followers with different diameters to study the influence of the diameter, other one is flat-shaped, other one is wedge-shaped and the last one is oscillating.
Such followers constitute cam-follower mechanisms, which transform the circular motion of the cam into a linear or angular motion of the follower. One or the other motion will depend on the configuration of the mechanism and, specifically, on the position of the follower with regard to either the cam or eccentric profile.
