Beschreibung
Zusammenfassung:	A manufacturing method of speed gear, comprising the steps of integrally molding, by either hot or warm forging, section of speed gear and section of clutch spline, rough-forming teeth of speed gear in the section of speed gear and involute spline parallel to axial line of gear in the section of clutch spline respectively, forming the involute spline parallel to axial line of gear formed on the section of clutch spline, by cold forging, into involute spline with back taper having a chamfer at the tip, and then finish forming the teeth of speed gear formed at the section of speed gear, the finish forming of teeth of speed gear being made by forming the teeth of speed gear by means of rolling dies, by cold forging, while turning them around the shaft hole perforated with reference to the section of clutch spline forming the involute spline with back taper, to provide a speed gear having section of speed gear and section of clutch spline including teeth of speed gear and involute spline with back taper having a chamfer at the tip, and manufacturing method and apparatus for it.
