Round eccentric 5 rotates about fixed axis A. Two other round eccentrics are rigidly attached to (or integral with) planet gears 2 which mesh wi th sun gear 3. Gear 3 rotates about fixed axis B. The eccentrics are of equal diameter and are encircled by collars of link 4. The eccentrics and link 4 form two paired parallel-crank linkages, CDKB and BKFE. Planet gears 2 are connected by turning pairs to carrier 1 which is designed as a housing that rotates about axes A and B. The pitch diameters of gears 2 and 3 are equal. The speeds n₁, n₃ and n₅ of carrier 1, gear 3 and eccentric 5 (in rpm) are related by the equation n₁=(n₃+n₅)/2.
