Abstract

See full text

An input gear assembly in which the input gear is coupled to the input shaft via a pair of spaced-apart pilot regions of the input shaft. One of the pilot regions is disposed adjacent to one of the bearings used, with the pilot region formed in or on the input shaft itself and engaging a corresponding internal surface of the input gear. Another of the pilot regions is formed in the inner bearing raceway of another of the bearings used, with the pilot region formed as an elongate portion of the inner bearing raceway of the input shaft and engaging another corresponding internal surface of the input gear. For manufacturing simplicity, this additional pilot region and the remainder of the elongate inner bearing raceway have the same material properties, surface treatment, straightness, and cylindricity. This arrangement prevents tilting of the input gear with respect to the input shaft and bearing shaft, thereby enhancing performance.
