ABSTRACT:
A gear roll-forming apparatus includes: a pinion die that is substantially the same in configuration and size as a bevel pinion; a pinion die holder for supporting the pinion die so as to allow rotation of the pinion die about a first axis of the pinion die while preventing axial movement B of the pinion die in an axial direction thereof from a small-diameter side toward a large-diameter side thereof; a gear die that is substantially the same in configuration and size as a bevel gear and meshes with the pinion die; and a pressing member for bringing a bevel gear blank into press contact with the pinion die, the bevel gear blank being arranged so as to sandwich the pinion die in cooperation with the gear die. By relatively rotating the gear die and the pinion die holder about a second axis of the gear die, the teeth of the pinion die are rolled with respect to the bevel gear blank.
