COMBINATION EPICYCLIC GEAR TRAIN Russian patent published in 2001 - IPC

FIELD: mechanical engineering. SUBSTANCE: proposed combination epicyclic gear train has high-speed and slow- speed stages and fixed wheel 9 with several rows of teeth-bridges common for both stages. Driven carrier 5 of high-speed stage is connected with driving sun gear of slow-speed stage, is arranged in middle part of fixed wheel 9 and is made in form of two similar disks. Driving sun gear of slow-speed stage consists of two similar gears 6 connected with disks of carrier 5 so that phases of their engagement with planet pinions 2 and 7 of both rows coincide. EFFECT: reduced axial dimensions, increased load capacity of gear train. 3 dwg
