Device And Method For Producing Bevels On Tooth Flanks Of Gearwheels

A cutting tool for producing a bevel on the edge defined by an end face of a gearwheel and the flanks of the teeth of the gearwheel adjacent thereto, with a cutting tool which at least comprises a cutting edge, wherein the gearwheel and the cutting tool are each driven in a rotary manner about a rotation axis in a predefined speed ratio, in such a way that the at least one cutting edge moves along a section of the edge removing material in an involute manner, wherein the rotation axes of the gearwheel and the cutting tool run parallel to one another and the direction of extension of the cutting edge has a directional component running in a radial direction relative to the rotation axis of the cutting tool, wherein the cutting edge processes only one processing section of the edge with each revolution of the cutting tool,

• including a carrier, which carries arranged about a tool rotation, wherein each of the cutting inserts comprises a cutting edge, wherein the cutting edges are arranged in an angular distribution about the rotation axis, in such a way that, with a uniform synchronous rotation of the carrier with a work gear, the cutting edges successively engage with teeth of the work gear which are different from one another, wherein at least some of the cutting edges of the cutting inserts are arranged angularly offset with respect to one another, in such a way that, with the uniform synchronous rotation, they engage at points on the teeth of the work gear which are different from one another.
