Abstract

A bevel gear drive with two bevel gears rotates about respective rotation axes intersecting at an intersection point, forming an angle of intersection. A computer determines the tooth shape of these tooth flanks based on data other than a tooth shape. The data are characteristic for a particular contact path represented by a sequence of contact points. The tooth shape of the tooth flanks is determined for several contact paths, with the interacting tooth flanks at all contact points having a common normal, which passes through a pitch point located between the two rotation axes and spaced from the intersection point equal to the radius r. Geometry data for the bevel gear are determined from the shape of the tooth flanks and stored in a format suitable for automatically generating a parts program for a processing machine with at least five axes.
