Carrier 1 rotates about fixed axis A and is connected by turning pair B to planet gear 3 which meshes with internal sun gear 2. Gear 2 rotates about axis A. Link 4 is rigidly attached to (or integral with) gear 3 and has straight slot a which slides along slider 5. Slider 5 turns about fixed axis C. When carrier 1 rotates at uniform velocity, gear 2 has a complex nonuniform rotational motion, determined by the dimensions of the links.
