Rotation is transmitted to driven bevel gear 1, keyed to shaft A, from gear 5 which is rigidly attached to carrier 4, and gear 6 which is rigidly attached to bevel gear 3. Bevel sun gears 1 and 3, of equal diameter, mesh with bevel planet gears 2 which are connected by turning pairs to carrier 4. The speeds n₁, n₅ and n₆ of gears 1, 5 and 6 (in rpm) are related by the equation n₁=2n₅-n₆. When the condition n₅=n₆/2 is satisfied, gear 1 is stationary.
