1,178,924. Epicyclic gearing. H. STOECKICHT, S.-M. STOECKICHT, A. W. STOE. CKICHT, A. H. VON ANKERSCHOFFEN and L. NIESSEN-STOECKICHT. 21 April, 1967 [11 June, 1966], No. 18583/67. Heading F2Q. In a planetary type gear train using straight or single helically toothed spur gears, the non- planetary elements are flexibly coupled to their respective torque transmitting or reacting members and only one element of the train is axially located relative to its torque transmitting or reacting member, the other elements being axially located by pressure rings 17-20, rigid with both ends of the non-planetary elements, which engage the end faces of the planet teeth and plain annular areas 24 within the dedendum circles thereof. As shown, an annulus gear 6 and a sun gear 11 are coupled to a fixed casing 1 and a shaft 12 respectively by splined coupling sleeves 7, 13 for limited universal movement relative thereto. Circlips 16 axially locate the annulus 6. Ring 20 is shrunk on to the hub of sun 11 and rings 17-19 are secured to the gear ends by screws 27. The ring bearing faces and the areas 24 are frustoconical, while the tooth ends 26 of the planets are convex and, in plan, rounded at their corners 29. The planet carrier may be the fixed gear element. |
