Transmission angle in mechanisms (Triangle in mech)

The transmission angle is an important criterion for the design of mechanisms by means of which the quality of motion transmission in a mechanism, at its design stage can be judged. It helps to decide the “Best” among a family of possible mechanisms for most effective force transmission. Literature on transmission angle in a planar 4-, 5-, 6- and 7-bar linkages and spatial linkages is organized. A survey of synthesis of mechanism with transmission angle control is made.
