PROCESSO DE FORMACAO POR FRESAGEM DE TOPO, DE UMA EMGRENAGEM CONICA EM ESPIRAL E ENGRENAGEM CONICA EM ESPIRAL

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.
