Abstract
709,384. Variable-speed gearing. PATENTVERWERTUNG W. REIMERS GES. April 28. 1952 [April 27, 1951], No. 10678/52. Class 80 (2) Expanding-wheel gearing comprises pairs of conical flanges 1, 2 and 3, 4, all simultaneously movable axially on their shafts 100 and 200 through levers by rotation of a control spindle 24 with oppositely-handed threads engaged by nuts 25, 33 carried by the levers, the flanges 2, 4 at one side of the gearing being moved directly by the lever 6 connected to the nut 25 while the flanges 1, 3 at the other side of the gear co-act, through balls 14 engaging cam surfaces, with rings 12, 13 mounted in rings 18, 26 carried by the levers 15, 16 which carry also rings 28, 29 bearing against the flanges 3, 1, the levers 15, 16 being connected to the nut 33 through a rocking lever 32. The levers 6 and 15, 16 are pivoted on nuts 23 and 27 engaging oppositelyhanded threads of a spindle 22, so that by rotation of the latter the nuts 23, 27 may be adjusted axially. As shown, rings 12, 13 are splined on shafts 100, 200 and the flange pairs 1, 2 and 3, 4 are splined on thin sleeves 19 loose on the shafts, but in a modification the flanges are splined on the shafts, the ring 12 is loose on the shaft 100 and is geared to an input (or output) shaft, while the ring 13 constitutes the output (or input) member.
