Abstract

321,672. Roano, A. May 15, 1928. Toothed wheels. - Gearing upon parallel or slightly inclined but intersecting shafts has teeth A, B of different helical inclinations on the two shafts, preferably steeper on the smaller wheel, in which case the reduction of drive obtainable is greater than is represented by the ratio of the diameters of the wheels. The wheels may be external or internal and may be double helical, in which case the different pairs may be spaced apart, may be relatively displaced circumferentially, and may have different pitches. The junctions x of one set of teeth may be cut away to accommodate the points of the other. The pitches may be so calculated that the drive is irreversible.
