Abstract

521,249. Toothed gearing. DESCHAMPS, E., and COLIN, R. Nov. 9, 1938, No. 32555. Convention date, Nov. 10, 1937. [Class 80 (i)] Two non-circular and non-elliptical gear wheels have pitch surfaces which are determined by polar equations given in the Specification. The wheels shown in Figs 3 and 3a each have two sets of staggered teeth XY the profiles of which are the envelopes of " a number of its tangents "or of " successive positions of a milling cutter ... represented by the circle of centre C," Fig. 3. The pitch surfaces are stated to be slightly out of contact in the neighbourhood of their maximum and minimum diameters. Teeth on the pitch surfaces of the wheels may be dispensed with.
