Abstract:
A method of chamfering and deburring the teeth of a gear, each of the teeth having a first and a second side and respective first and second end faces, the method comprising:meshing the gear with first and second tools, each tool comprising a ring gear having first and second tool teeth meshing with the gear teeth at edges formed between the first and second sides and, respectively, the first and second end faces; exerting compression between the gear teeth and the first tool teeth, thereby effecting a first permanent deformation of the gear teeth between, respectively, the first and second sides and the first and second end faces to form a chamfer having a first curl on, respectively, the first and second sides and a second curl on, respectively, the first and second end faces; and exerting compression between the gear teeth and the second tool teeth, thereby effecting a second permanent deformation of the gear teeth between, respectively, the first and second sides and the first and second end faces to flatten said first curl of the chamfer on the first and second sides.
