TOOTH TAKING-OUT FORGING METAL MOLD, MANUFACTURING METHOD THEREOF AND MANUFACTURING METHOD OF HELICAL GEAR

摘要

PROBLEM TO BE SOLVED: To provide a tooth taking-out forging metal mold, a manufacturing method thereof and a manufacturing method of a helical gear using such a tooth taking-out forging metal mold, which is inexpensive, short in a lead time, and high in accuracy.;SOLUTION: The tooth taking-out forging metal mold is a metal mold used for tooth taking-out forging of the helical gear of an internal tooth or an external tooth, and is manufactured by forming a groove (a female helical tooth) for forming a tooth shape of the helical gear to a metal mold raw material 20 by a gear shaper 10. The tooth taking-out forging of the helical gear of the internal tooth or the external tooth is executed by using such a tooth taking-out forging metal mold.;COPYRIGHT: (C)2014,JPO&INPIT
