Abstract: To attain an antitwist helical gear tooth flank with longitudinal tooth crowning, a novel additional rotation angle is proposed for the work gear during its hobbing process. A congruous nonlinear function with two variables ...

Abstract: To doublecrown an involute helical gear, a hobbing method is proposed by setting the hob's diagonal feed motion as a secondorder function of hob's traverse movement and modifying the tooth profile of hob cutter into a ...
