Britannica Editors History Britannica AI Ask Anything Table of Contents Table of Contents Ask Anything mechanism , in mechanical construction, the means employed to transmit and modify motion in a machine or any assemblage of mechanical parts. The chief characteristic of the mechanism of a machine is that all members have constrained motion; i.e., the parts can move only in a determinate manner relative to one another. The nature of these relative motions is determined largely by the number of parts and the way in which they are connected. Related Topics: machine Dutch system (Show more) See all related content Regardless of its complexity, the mechanism of a machine can always be analyzed as an assemblage of simple basic mechanisms, each of which contains members or links that transmit motion from one moving link to another with or without modification in degree or kind. In general, there are three ways in which this can be done: by a wrapping connector such as a chain ( q.v. ) or belt ( see belt drive ); by direct contact as in a cam or gear ( qq.v. ); or by a pin-connected link ( see linkage ).
