Method for manufacturing e.g. bevel drive gear of commercial vehicle, involves finely treating spiral tooth system in hard machining process after hardening process by hard machining step formed as skiving process

摘要

The method involves bringing a spiral tooth system into a soft machining process by a continuously dividing rolling process in a two-flank section by a one-piece knife head into a blank (13). The spiral tooth system is hardened in a hardening process (14) and finely treated in a hard machining process (15) by a stick blade after the hardening process by a hard machining step (16) formed as a skiving process, where the stick blade comprises a common center. The spiral tooth system is brought at constant teeth height and enlarged epicycloid as a flank longitudinal line. An independent claim is also included for a spiral bevel gear for a commercial vehicle, comprising spiral teeth.
