Stirnrad für ein Schneckengetriebe und eine Form zur Herstellung eines solchen Stirnrads

摘要

The invention relates to a spur pinion (11) for a worm gear. The inventive pinion is provided with at least two wheel discs (12, 13, 14) having a cylindrical or truncated front face. The wheel discs adjoin each other at a boundary surface (15). The teeth of the two adjacent wheel discs verge into each other in a continuous manner on said boundary surface. At least one of the front faces converges in the direction towards the boundary surface in such a way that the teeth of all the wheel discs can mesh with the same worm. The invention also relates to an embodiment for producing the inventive spur pinion.
