Link 1 rotates about fixed axis A and carries three pins a at equal distances from axis A and located symmetrically at angles of 120°. Pins a slide in six straight radial slots b of link 2 which rotates about fixed axis B. The angles between the axes of adjacent slots equal 60°. When driving pin wheel 1 rotates continuously at uniform velocity, driven link 2 rotates at nonuniform velocity. The average transmission ratio from pin wheel 1 to link 2 is i₁₂= 2. Links 1 and 2 rotate in the same direction.
