Abstract:
A bevel gear pair comprising:a pinion having a plurality of first gear teeth each defined at least in part by a tooth root and convex and concave flank surfaces, said flank surfaces each defining a plurality of microstriations extending thereacross; a ring gear having a plurality of second gear teeth meshable with said first gear teeth, each of said second gear teeth being defined at least in part by a tooth root and convex and concave flank surfaces, each of said flank surfaces having a plurality of microstriations defined thereby; said microstriations of said pinion being oriented along a meshing direction established when said ring gear and pinion are operated together, and said microstriations defined by said flank surfaces of said ring gear extending approximately parallel to said root of each of said second gear teeth; and whereby said pinion and said ring gear are produced individually and can be randomly chosen from a plurality of ring gears and pinions and be operated together to generate noise levels approximately equivalent to those of match bevel gear pairs.
