Abstract

PURPOSE:To manufacture an intermittent spline shaft quickly and in large quantities by pressure welding two thread rolling dies in which intermittent part and rolled threads are arranged alternately on the circumference in the direction of diameter of a work and rotating the two thread rolling dies synchronously. CONSTITUTION:Thread rolling dies 2, 3 are brought into contact at a position opposite to each other in the direction of diameter of a work 1. In the case where rolling is to be made so as to make, for instance, 9 crests out of 28 spline crests intermittent to the work 1, Intermittent parts 6, 7 of 8 crests are provided on the dies 2, 3 at intervals of 20 crests to rolled thresds 4, 5 which are integer times as many as 28 crests. At the time of setup, the part with spline crests of the thread rolling dies 2 is placed on the work 1, and the part without spline crests of the thread rolling die 3 is placed on the work 1. The thread rolling dies 2, 3 are pressed against the work 1 while rotating them synchronously. By this way, a spline shaft excellent in strength and accuracy are obtained with smaller number of processes compared with machining.
