Claims

[Scope of utility model registration request]

A work head for holding a bevel gear, a spindle shaft provided to be rotatable relative to the bevel gear held by the work head, and a cutter head provided at the lower end of the spindle shaft and having a plurality of cutters. and a cam disposed above the spindle shaft, the spindle shaft is moved up and down by the rotation of the cam, and while the cutter is rising, the work bed is rotated by one tooth of the bevel gear. In a gear cutting device for a bevel gear configured to move, a plurality of cutters provided on the cutter head are divided into a rough cutting cutter and a finishing cutting cutter, and the shape of the cam is adjusted so that the rotation angle of the cam is 0°. The part between the predetermined angle and the cam's rotation center is arranged so that the distance from the cam's rotation center to the outer periphery gradually increases, and the part where the distance from the cam's rotation center to the outer periphery gradually increases, and the part that does not change is located alternately, and the distance from the cam's rotation center to the outer periphery is A gear cutting device for a bevel gear, characterized in that it is configured to provide a maximum portion.
