Abstract
There is provided a rolling die and a method for forming a thread or worm and a spline having a small number of teeth whose number is thirteen or less simultaneously by rolling. By use of rolling dies, the formation of a worm by rolling by use of a thread rolling die starts, and after that, the formation of a spline having a small number of teeth by rolling starts by use of a spline rolling die while continuing the formation of the worm. Accordingly, a rolled material can be rolled forcibly by a driving source from the worm rolled using the thread rolling die. As a result, the spline having a small number of teeth whose number is thirteen or less can be formed by rolling onto the rolled material at the same time as the formation of the worm.
