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 ...

Abstract: Prior to the development of sophisticated computer numerical control (CNC), both face milling (FM) and face hobbing (FH), the two most popular technologies for bevel gear production, required cradle-type machines with ...
