Carrier 1 rotates about fixed axis A and is connected by turning pair B to planet gear 2 which meshes with fixed sun gear 3. Planet gear 2 has roller 4 which rotates about axis C. Roller 4 slides along curvilinear slot a of slotted link 5 which rotates about axis A. The sizes of the links comply with the conditions: r₃=2r₂ and B͞C=r₂, where r₂ and r₃ are the pitch radii of gears 2 and 3. Point C describes epicycloid q-q. Slotted link 5 has short dwells when point C is in positions C' and C".
