はすば円すい形インボリュート歯車のオーバボール法の開発

抄録

An over-ball measurement of helical conical involute gear is newly developed. This method makes it possible to control the finished size of the gear in hobbing and grinding. First the over-ball distance is obtained analytically, and next is verified by experiments. Besides, how to apply this measurement to controlling the infeed distance in practical hobbing and grinding is presented.
