Patent ID: 6918181

Claim:
A method for producing intermeshing gears having improved acoustic characteristics, said gears having a plurality of intermeshing gear teeth each defining a gear tooth profile and a face surface, said method for application on a pre-processed baseline gear and characterized by: determining a variable component of transmission error due to mesh stiffness variations of said intermeshing gear teeth of said baseline gear; determining a process-induced transmission error due to dimensional changes effected by an isotropic surface finishing process of said gear teeth of said baseline gear; determining a first Gear Tooth Topological (GTT) modification for said gear teeth to compensate for said variable component of transmission error of said baseline gear; determining a second Gear Tooth Topological (GTT) modifications for said gear teeth to compensate for said process-induced variable transmission error of said baseline gear; summing said first and second Gear Tooth Topological (GTT) modifications for determining a resultant GTT modification; finish grinding said gear teeth in accordance with said resultant GTT modification, and isotropic processing of said gear teeth to produce smooth gear tooth face surfaces.
