GEOMETRICAL CHARACTERS AND TRANSMISSION ANGLE OF THREE TYPES OF CRANK AND ROCKER MECHANISM

This paper gives a strict mathematical proof of the four-bar length conditions of threetypes of crank and rocker mechanism, that is, central, positive-offset and negative-offsettypes. Systematic analysis has also been made of the geometrical characters of these types ofmechanism, their minimum transmission angle and its location. The problems discussed inthis paper are crucial to both kinematical and dynamical analysis and generalization of thecrank and rocker mechanism.
