METHOD OF FORMING FACE MILL OF SPIRAL BEVEL GEAR WITH INTEGRAL CENTRAL STRUCTURE AND SPIRAL BEVEL GEAR FORMED THROUGH SAID METHOD

摘要

A gear blank is integrally formed with a shaft or other central structure protruding axially from what is to be the toothed face of the gear. A spiral bevel gear is then cut by the face mill generation method, but with the cutter distance exceeding the outer cone distance. The cutter does not intrude into the area occupied by the shaft. The resulting gear has a negative spiral angle and a reverse tooth curvature.
