Abstract
This invention deals with a system and method for manufacturing a drive gear having a plurality of teeth in cross section where the teeth are situated on a drive shaft in a substantially parallel manner. The drive gear is characterized in that the teeth are substantially parallel to each other and contact mating driven teeth at points which define an arc which is not concentric about an axis of the driven gear. The drive gear is characterized in that it has multi-tooth contact points which do not contact the teeth of the mating gear at exactly the same contact point on the mating teeth, thereby lengthening the life of the driven gear as well as distributing the torque load to a plurality of teeth. A method and procedure for generating a drive gear having the features of the present invention is also disclosed.
