Abstract:
1. A gear system comprising: a pinion having a pinion tooth number (N a mating gear having a mating-gear tooth number (N wherein the pinion and the mating gear form a gear pair having a gear ratio (m wherein the relative curvature of the first-tooth profile and the second-tooth profile is a multiple of a reference relative curvature (K and K m is a relative curvature multiplier that is more than a i,j −δ and less than a i,j +2δ, where δ is between 0 and 0.15 and a i,j is defined by a predetermined relationship between the gear ratio (m G ) and the face-width factor (f w ), the predetermined relationship corresponding to at least one relative curvature multiplier value in a relative curvature multiplier value table having the following properties:
