1,056,520. Toothed gearing. SIMMERING GRAZ PAUKER A.G. FUR MASCHINEN-, KESSELUND WAGGONBAU. Aug. 4, 1964 [Oct. 31, 1963], No. 31224/64. Heading F2Q. The planets 3 of an epicyclic gear, having a sun 1, and an annulus 2, run on pins 4 eccentrically pivoted in the planet carrier and having integral arms 5 which are linked by links 6 to a central rod 8 movable in a plane perpendicular to the gear axis so that the planet tooth loadings are equalized. The pivotal axes of the pins 4 are outside or alternately outside and inside the planet axes. In a modification, Fig. 3 (not shown), the end of one pin arm 5 forms a fulcrum 11 for a bell-crank 10 pivoted to one end of the central rod 8 and by a slotted end and pin 111 to an adjacent pin arm 5. In a further modification, Fig. 4 (not shown), the central rod 8 is pivoted at each end to the centre of beam 13 pivoted by a pin 14 and a slotted hole and pin 141 to two facing pin arms 5. In another modification, Fig. 5 (not shown), the pin arms 5 are connected by links 17, arranged along the sides of a square, to a central ring or plate 19. In further modifications, Figs. 6 and 7 (not shown), pins 22 on the ends of the pin arms 5 engage open-ended or closed slots 21 in a central plate 20. Elastically deformable bushes may be provided at the arm-link and link-central plate or rod joints. Reference has been directed by the Comptroller to Specification 905,616.
