Abstract

645,177. Variable-speed gearing. MADSEN, J. June 23, 1948. No. 16870. Convention date, June 24, 1947. [Class 80(ii)] Change-speed gearing giving two forward speeds and reverse comprises stepped planet pinions 4, 8 carried by a disc 6 secured to the driven shaft 7, the part 8 meshing with a wheel 9 having a hub 10 loose on the shaft 7 while the part 4 meshes with a wheel 3 secured to the driving shaft 1 and with internal teeth on a disc 2 having a hub 11 loose on the shaft 1. Skew bushes 12 and 13, 14 are slidable on but rotate with the hubs 11 and 10 respectively and coact with encircling straps 15, 16, 17 connected with the pistons of pairs of liquid pumps 18, 21, 23, each pair of pumps being interconnected by a conduit 25, 26, 27. The pumps 18, 23 are mounted on the stationary casing while the pumps 21 rotate with the' disc 6. With all the bushes positioned so that the operative eccentricity is zero (as shown at 12, 14), all the pumps are inactive and no drive is transmitted. By sliding the bush 12, or, 13, or 14 to its other position of maximum operative eccentricity, the pumps 18, or 21 or 23 become operative and prevent rotation of the disc 2, or rotation of disc 6 relative to wheel 9, or rotation of wheel 9, so that reduced forward drive, or direct-drive, or reverse, respectively, is obtained.
