Patent ID: 7651383

Claim:
A method of lapping a gear set comprising first and second gear members with said first gear member having a plurality of tooth flank surfaces and said second gear member having a plurality of tooth flank surfaces, said method comprising: defining a plurality of grid points on the tooth flank surfaces of each of said first and second gear members, determining a lapping correction for more than one of said plurality of grid points, said lapping correction having a magnitude and defining an amount of lapping time at each of said more than one of said plurality of grid points whereby an amount of stock material is removed at said each of said more than one of said plurality of grid points, wherein the amount of stock material removed at each of said more than one of said plurality of grid points is dependent upon the magnitude of the lapping correction at the respective each of said more than one of said plurality of grid points, lapping said gear set by rotating said first gear member in mesh with said second gear member in a manner such that contact between the members is shifted from at least a first grid point to a second grid point whereby lapping contact is maintained at each contacted grid point for a time sufficient for removal of said amount of stock material at said each contacted grid point.
