GEAR MACHINING APPARATUS AND MACHINING METHOD

摘要

A machining section of a gear machining apparatus includes a workpiece support in the form of a shaft that pivotally supports the workpiece gear and a cutter support in the form of a shaft that supports the chamfering cutter so that the chamfering cutter meshes with the workpiece gear attached to the shaft. The shaft is angled so that the chamfering cutter meshes with the workpiece gear at an axis-crossing angle to being zero degree and machining teeth of the chamfering cutter do not interfere with a tooth face the workpiece gear. A gear machining method is also provided.
