Abstract
Systems and methods are described for shoulders that can be implemented on shafts in gear systems, such as a drive train. The shoulders, in combination with other components like bearings, or nuts, can help restrict movement of the shaft within the drive train. Use of the shoulders in various embodiments can avoid the need for grind reliefs in corners. Grind reliefs can help in prior art systems where machining or grinding is used at surfaces where raceways of bearings border shoulders that are integrated with the shaft. Grind reliefs create tight spaces where edge breaks are difficult to create. Press-fit shoulders, such as described herein, allow machining and edge break creation on the shaft prior to installation of the shoulder.
