In mechanical engineering, a cam is a mechanical device made of a material (wood, metal, plastic, etc.) That is secured to a shaft and has a specially shaped contour. Thus, the shaft rotation causes the profile or contour of the cam touch, move, push or connect a piece known as a follower. There are two types of followers, translation and rotation.
The union of a cam is known as a union of a point in case of a plane or line join if space. If necessary, you can add teeth to the cam to increase the contact.
a cam design depends on the type of movement to be printed in the supporter. Examples are the camshaft the internal combustion engine, the programmer washing, etc.
can also perform a classification of the cams in their nature. Thus, no revolution, translational, desmodromic (these are those that perform a dual action effect), etc.
The machine is used to make paddles is known as a generator.
