1.The Fundamental Law of Gearing Tooth profile 1 drives tooth profile 2 by acting at the instantaneous contact point K. M,N,is the common normal of the two profiles. velocities V,and V,at point K,along N,N,are equal in both magnitude and direction.Otherwise the two Otootiprofleszwould separate from each other
