Abstract

1,157,562. Toothed gearing. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. 26 Oct. 1967 [9 Jan., 1967], No. 1091/67. Heading F2Q. A Wildhaber-Novikov gear has on each tooth at least one convex relief surface such that the profile of the relief surface extends between the tooth tip and a point of common tangency with the profile of a working surface. In the case of a convex working surface (Fig. 3), the radius of curvature of the relief surface is less than that of the associated working surface. The relief surfaces of each tooth profile may have separate centres of curvature Cr1, Cr2 as shown, or a common centre of curvature Cr (Figs. 1, 2, not shown). This relief reduces tooth tip loading when the transmitted torque is high and/or the centre distance between gears is incorrect, to obviate surface fatigue and scuffing.
