Carrier 1 rotates about fixed axis A and is connected by a turning pair to rigidly attached planet gears 2 and 4. Gear 2 meshes with fixed internal gear 3; gear 4 meshes with internal gear 5 which rotates about fixed axis B. If the numbers of teeth of gears 2, 3, 4 and 5 satisfy the condition z₄>z₂ and z₅>z₃, then the speeds n₁ and n₅ of carrier 1 and gear 5 (in rpm) are related by the equation n₅=n₁(z₃z₄-z₂z₅)/(z₂z₅) where z₂, z₃, z₄ and z₅ are the numbers of teeth of gears 2, 3, 4 and 5. Carrier 1 and gear 5, in this case, rotate in opposite directions.
