Patent ID: 11130183

Abstract:
The invention provides a tool, a method and a machine with which roof ridge-shaped chamfers can be produced on teeth of an internally and externally toothed gearwheel with minimised changeover times during tool set up. For this purpose, a tool according to the invention comprises a tool carrier having a holding section for attachment in a tool holder and a chamfering tool, which is held on the end section of the tool carrier, said end section being associated with the other end face, and during use describes an impact circle with its cutting edge, the diameter of said circle being determined by the radial distance of the cutting edge of the chamfering tool from the axis of rotation of the tool. According to the invention, at least one further chamfering tool is attached in a middle section of the tool carrier which is offset relative to the end section provided with the chamfering tool towards the holding section of the tool carrier. At the same time, the further chamfering tool is held with its cutting edge at a radial distance from the axis of rotation of the tool, which is greater than the radial distance of the cutting edge of the chamfering tool held on the end section of the tool holder. A method according to the invention and a machine according to the invention are based on the use of tools according to the invention.
