Gear tooth alignment by accommodation
First Claim
1. A method of gear tooth alignment in a two stage cluster assembly having a first gear as a first piece, hardened and ground separately, having a shaft and a second stage pinion as a second piece, hardened and ground separately, and having a bore in a multi-cluster gear train system comprising the steps of:
- fitting loosely the shaft of the first piece and the bore of the second piece;
welding an area of contact of the first piece and the second piece to form a compact cluster;
assembling the compact cluster in said multi-cluster gear train system; and
isolating mass of first piece from the masses of the remaining component of the gear train system.

Abstract
Apparatus and method for gear tooth alignment by accommodation in more than one stage gear cluster assembly. This arrangement essentially isolates the mass of one gear member in a cluster assembly from that of the other and makes the effective mass at the gear mesh to be equal to or less than that of a gear on either end of the gear shaft with respect to its connected masses. This permits a design for extremely high power ratio for a gear train by isolating inertias of the elements and reducing dynamic loads and forming a torsionally soft shaft to allow alignment of the gear teeth by accommodation by allowing the unbalanced load in between the gears to enable the gears to mesh together.
