ABSTRACT:
Two coaxial main shafts are the output and the input of a variable-speed-ratio transmission wherein a transfer gear on one of these shafts is in permanent mesh with a plurality of coacting gears on respective ancillary shafts paralleling the main shafts, each ancillary shaft also carrying one or more speed-changing gears in permanent mesh with one or more associated gears mounted idle on the other main shaft and adapted to be selectively clutched thereto. The transfer gear has an annular body with external teeth which surrounds its supporting shaft with clearance, a flexible ring being disposed in that clearance with freedom of limited radial deformation and in positive engagement with both the shaft and the gear body to interconnect them for joint rotation. Teeth or other coupling formations on the inner and outer ring surfaces, peripherally offset from one another and separated by freely deformable ring sections, engage complementary formations on the shaft and within the gear body, respectively.
