Carrier 1 rotates about fixed axis A and is connected by turning pair B to planet gear 2 which meshes with fixed internal sun gear 3. Gear 2 has rigidly attached pin a which rotates about axis C and slides along slot b of slotted link 4. Link 4 reciprocates in fixed guides d-d. 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 travels along a straight line that coincides with a diameter of gear 3. The angular velocities ω₁ and ω₂ of carrier 1 and planet gear 2 are of equal magnitude and opposite sign. The velocity of link 4 is v₄=(v_c) cos(α) where v_c is the velocity of point C on gear 2, and α is the constant angle between line AC and axis x-x.
