1,030,611. Toothed gearing. RHEINSTAHL HUTTENWERKE A.G. Jan. 31, 1963 [Feb. 10, 1962], No. 3999/63. Heading F2Q. In epicyclic or countershaft toothed gearing wherein a number of planetary or countershaft pinions 8 in a carrier 7 are interposed between a sun or central gear 2 and a coaxial ring gear 9, resilient means are provided to allow relative radial, axial and angular movements between the carrier 7, gear 2 and gear 9 in order to equalize the load carried by the pinions 8. In the double helical epicyclic gear shown the input sun 2 is floatingly connected by a resilient torsionally yieldable coupling 3 to a diesel engine flywheel 4, the output carrier 7 is floatingly connected to a driven machine by a torsionally yieldable resilient coupling 11, and the reaction ring gear 9 is fixed in a housing supported on resilient elements 16. Labyrinth sealing elements 19, 20 are provided. In a modification, Fig. 5 (not shown), the sun 2 is fixed to the housing, and the carrier 7 and gear 9 are floatingly coupled respectively to input and output shafts. In another modification, Fig. 6 (not shown), the couplings 3, 11 and resilient mounting 16 are replaced by multiple spring plate couplings of the type shown at 60, Fig. 7, which couplings are torsionally rigid. In Fig. 8 (not shown) such a coupling is inserted between a driven carrier 7 and the shaft 69 of a rope drum, the ring gear being fixed in a resilientlysupported housing. In further modifications, Figs 9-11 (not shown), two epicyclic gear trains are connected in series by resilient couplings comprising (Fig. 9) oppositely-loaded coil springs one within the other (Fig. 10) an elastically flexible shaft, and (Fig. 11) a multiple spring plate coupling. The gear housing in these modifications is supported by cup springs. In a non-epicyclic modification of the Fig 1 arrangement employing straight toothed wheels, Fig 3 (not shown), the carrier 7 is fixed to the resiliently supported housing, the ring gear 9 is floatingly coupled to the output shaft, and the pinions 8 are supported by needle bearings and spacer rings. |
