Gears 2 and 5 rotate about fixed axis A and are rigidly attached to (or integral with) shaft 9. Gears 2 and 5 mesh with planet gears 8 and 7. Gear 7 meshes with fixed internal gear 3. Carrier 1 is rigidly attached to internal gear 4 which meshes with planet gear 8. Carrier 6 is rigidly attached to (or integral with) shaft 10 which rotates about fixed axis B. Internal gear 4 rotates freely about shaft 10. Thus, driving shaft 9 transmits rotation in the same direction to two driven links: shaft 10 and internal gear 4. The speeds n₅, n₄ and n₆ of gears 5 and 4 and carrier 6 (in rpm) are related by the equations n₄=n₅(z₃/z₃+z₅) and n₄=n₅(z₂(z₃+z₅)+z₄z₃)/((z₂+z₄)(z₃+z₅)) where z₂, z₃, z₄ and z₅ are the numbers of teeth of gears 2, 3, 4 and 5.
