D09. Double Slider-Crank Mechanism-Inversion
full metadata

In model D-9, the crank link is grounded, and the cross-block rotates in an epicycloid motion equivalent to a large circle rotating on its inside circumference on the outside of a smaller circle of diameter equal to the length of the crank link between centers of the two cylindrical joints. Reuleaux called this motion Cardanic circles, and called this mechanism a turning cross-block. A version of this mechanism is used in Oldham’s coupling (Model Z-5) to produce uniform rotation about two parallel shafts.
