These traditional machines generally prepare many indexing change gears for gear cutting. But when we cut the gear of a prime number of teeth, the indexing change gear is not prepared for more than about 100 teeth of the gear. In such a case, we have to correct the indexing of the number of teeth using a differential gear to cut a helical gear, but when we apply the prime number of teeth on the helical gear, we cannot choose an arbitrary feed speed. Therefore, in this paper, we report on a new indexing mechanism for the prime number of gear teeth using a double differential gear device, which reduces the number of indexes the change gear must go through.
