Rotary sun bevel gear 1 is keyed to shaft a, rotates about fixed axis A-A and meshes with bevel planet gears 2 and 4 which have the angle α between their axes. Gears 2 and 4 mesh with fixed bevel sun gear 3. Carrier 5 is designed as a cross-shaped member with pins b that are connected by turning pairs to planet gears 2 and 4. Shaft c of carrier 5 rotates about axis A-A. The speeds n₁ and n₅ of shafts a and c (in rpm) are related by the equation n₅=n₁(z₁)/(z₁-z₃) where z₁ and z₃ are the numbers of teeth of gears 1 and 3.
