Abstract:
A method for determining a geometry of a tooth working surface of a conjugated gear having a predetermined gear tooth contact area, said method including the steps of:(a) defining a conventional tooth working surface; (b) defining said predetermined gear tooth contact area within said conventional tooth working surface; (c) modifying said conventional tooth working surface to define a modified tooth working surface having said predetermined gear tooth contact area, wherein said conjugated gear has a longitudinal axis and said tooth working surface of said conjugated gear is defined by a face line and a root line defining a tooth height and by a toe line and a heel line defining a tooth depth, and the step (b) includes the steps of: selecting a first boundary line of said predetermined gear tooth contact area perpendicular to said gear axis and located at a predetermine distance from said toe line; selecting a second boundary line of said predetermined gear tooth contact area perpendicular to said gear axis and located at a predetermine distance from said heel line (15); selecting a third boundary line of said predetermined gear tooth contact area parallel to said face line and located at a predetermine distance from said face line; selecting a forth boundary line of said predetermined gear tooth contact area parallel to said root line and located at a predetermine distance from said root line.
