A drive mechanism for a reciprocating and multiple step index mechanism to achieve smooth starting and stopping action with controlled acceleration and decleration. It is characterized by extremely flexible kinematic characteristics achieved by the superposition of a constant velocity, fundamental and a higher harmonic component. The mechanism utilizes pairs of rotating drive members and eccentric members mounted in non-rotational relation, the pairs being connected to rotate in a multiple integral angular velocity ratio. An output member is arranged in driving relation to one of the eccentric members and is influenced also by the rotation of the other eccentric member. Power input is directed to one of the pairs of drive members. |
