Power skiving tool for power skiving gear teeth on a crown wheel workpiece

A power skiving tool for producing several tooth gaps by means of a power skiving method on a ring-shaped or disk-shaped workpiece, which has a workpiece axis of rotation, the power skiving tool comprising:

• a tool axis of rotation thereof;
• a skiving conical body arranged rotationally-symmetrically to the tool axis of rotation and defining a hyperboloid or truncated cone;
• and
• a plurality of cutting teeth, which protrude approximately radially out of a lateral surface of the skiving conical body;
• wherein each of the cutting teeth has a rake face and at least one cutting edge,
• wherein each rake face defines a cutting surface normal, which encloses an acute angle less than about 40°, with respect to the tool axis of rotation, and wherein the power skiving tool is configured for axially-offset power skiving of the workpiece, and
• wherein at least two of said cutting teeth are located on different diameters of the skiving conical body.
