US 12,427,565 B2 · Device and method for producing a spur toothing

Abstract

A device for producing a spur toothing includes a tool holder arranged for rotational drive about a drive axis and longitudinal displacement along the drive axis, and a tool arranged on the tool holder. The tool includes an end face, a mating toothing disposed on the end face and arranged for forming a spur toothing on a workpiece, and a longitudinal axis arranged at an angle to the drive axis such that the longitudinal axis meets the drive axis at a wobble point. The mating toothing has a tooth base plane and the wobble point is disposed on the drive axis in front of or behind the tooth base plane such that, through rotary drive and longitudinal displacement of the tool holder with the associated wobbling rolling of the tool on the workpiece, the spur toothing formed by the mating toothing has a number of teeth that is unequal to a number of teeth of the mating toothing.

A device for producing a spur toothing, comprising:

a tool holder arranged for rotational drive about a drive axis and longitudinal displacement along the drive axis;
and
a tool arranged on the tool holder, the tool comprising:
an end face;
a mating toothing disposed on the end face and arranged for forming a spur toothing on a workpiece, the mating toothing comprising a tooth base plane;
and
a longitudinal axis arranged at an angle to the drive axis such that the longitudinal axis meets the drive axis at a wobble point, wherein the wobble point is disposed on the drive axis in front of or behind the tooth base plane such that, through rotary drive and longitudinal displacement of the tool holder with the associated wobbling rolling of the tool on the workpiece, the spur toothing formed by the mating toothing has a first number of teeth that is unequal to a second number of teeth of the mating toothing, and the mating toothing comprises a plurality of embossing teeth and a plurality of guide teeth.

4 more elements

A device for producing a spur toothing, comprising a tool holder with a tool arranged thereon, the tool having a mating toothing on an end face for forming a spur toothing on a workpiece, the tool holder being designed for a rotational drive about a drive axis and for longitudinal displacement, a longitudinal axis of the tool being arranged at an angle to the drive axis of the tool holder such that the longitudinal axis of the tool meets the drive axis of the tool holder at a wobble point,

wherein the wobble point is offset relative to a tooth base plane of the mating toothing of the tool along the drive axis in front of or behind the tooth base plane in such a way that, through rotary drive and longitudinal displacement of the tool holder with the associated wobbling rolling of the tool on the workpiece, a toothing with a first number of teeth that is unequal to a second number of teeth of the mating toothing of the tool is produced on the workpiece, and the mating toothing comprises a plurality of embossing teeth and a plurality of guide teeth.
