Abstract
A method of chamfering and deburring the teeth of a gear having first teeth, each of the first teeth having a first and a second side and respective end faces; the method providing for meshing the gear with at least one tool having a ring gear meshing with the first teeth at edges formed between the first and second sides and the end faces; exerting compression between the first teeth of the gear and the ring gear; effecting a first permanent deformation of the edges to form first chamfer faces; and effecting at least a second permanent deformation between the first and second sides and the respective end faces; the first and the second permanent deformation being effected by means of enbloc tools having a first number of teeth and a second number of teeth.
Claims19
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.
A tool for chamfering and deburring the teeth of a gear, each gear tooth having first and second sides and first and second end faces, the tool comprising:
- a ring gear having first tool teeth and second tool teeth adapted for meshing with the gear teeth at edges formed between the first and second sides and, respectively, an end face thereof, said first tool teeth respectively effecting a first permanent deformation of the gear teeth to form a chamfer having a first curl on, respectively, the first and second sides and a second curl on, respectively, the end face, and said second tool teeth respectively effecting a second permanent deformation to flatten said first curl of the chamfer on the first and second sides,
- wherein said first tool teeth are adjacent to each other, each tooth meshing with two adjacent said gear teeth to effect said first permanent deformation;
- and
- said second tool teeth are adjacent to each other, each tooth meshing with two adjacent said gear teeth to effect said second permanent deformation.
A tool for chamfering and deburring the teeth of a gear each gear tooth having first and second sides and first and second end faces, the tool comprising:
- a ring gear having first tool teeth and second tool teeth adapted for meshing with the gear teeth at edges formed between the first and second sides and, respectively, an end face thereof, said first tool teeth respectively effecting a first permanent deformation of the gear teeth to form a chamfer having a first curl on, respectively, the first and second sides and a second curl on, respectively, the end face, and said second tool teeth respectively effecting a second permanent deformation to flatten said first curl of the chamfer on the first and second sides,
- wherein said ring gear comprises at least a first and at least a second portion with said at least a first and at least a second portion being complementary to each other, said at least a first portion comprising said first tool teeth, and said at least a second portion comprising said second tool teeth.
