摘要： PROBLEM TO BE SOLVED: To provide a form rolling tool capable of form-rolling a few teeth spline with ≤13 teeth.
SOLUTION: According to this form rolling tool 1, since the bottom land 21a of a chamfer part 21 is ascendingly tilted from the termination side to the start edge side in the form rolling direction, even when its chamfered angle α is set to an angle same as that of the conventional form rolling tool 101, the root side of each working tooth 3 is cut, and the area (length along the form rolling direction) of the tip face ( top-cut face 31) of the working tooth 3 can be made large. As a result, the contact area between each working tooth 3 and each tooth of the stock to be form-rolled is secured, and the non-contacting between each working tooth 3 and each tooth of the stock to be form-rolled can be prevented, thus the stock to be form-rolled is rolled at a suitable rotary pitch, and a few teeth spline with ≤13 teeth can be form-rolled.

摘要： PROBLEM TO BE SOLVED: To provide a form rolling tool, and a simultaneous form rolling method of a screw or a worm with a spline having a small number of gears capable of simultaneously form rolling the screw or the worm with the spline having a small number of gears of ≤13.
SOLUTION: A form rolling tool 1 has a configuration in which the form rolling of a worm by a screw form rolling tool 2 is started first, and the form rolling of the spline having a small number of gears is started next by a spline form rolling tool 5 while continuing the transfer of the worm by the screw form rolling tool 2, and can forcibly rotate a material M to be form-rolled with the worm to be form-rolled by the screw form rolling tool 2 as a driving source. Thus, the spline having a small number of gears of ≤13 can be form-rolled on the material M simultaneously with the form rolling of the worm.
