Abstract
A gear box having a carburized shaft and steel bearing assembly. The bearing includes an inner-race and an outer-race. The shaft includes a distal end surface extending perpendicularly from a shaft faying surface and a shaft annular beveled edge. The shaft faying surface is in intimate contact with the inner-race. The inner-race second annular face is coplanar with the distal end surface. The shaft annular beveled edge cooperates with the inner-race faying surface to define a half-V shaped groove. An annular weld joint is formed in the half-V shaped groove thereby joining the shaft to the inner-race. The outer-race includes a first width (W) and the inner-race includes a second width (W). Wis wider than Wby greater than 0 millimeters (mm) to about 10 mm.
