Paper Abstract

The equal-angle spiral has been widely used in instrument manufacture. But because of the characteristic of equal-angle spiral the difference between maximum and minimum arms of force is slightly big and the minimum arm of force is slightly small. This is not profitable to the cam. Instead of the equal-angle spiral in this paper a new type of cam contour returning zero is proposed which makes that the change of the arm of force in the whole working range is smaller and the value of the minimum arm of force is increased. Hence the flexibility of transmission of returning zero cam is also increased.
