Abstract
In the finish roll forming, it inevitably yields both the concaving of tooth profile and the plastic deflection of addendum of teeth. In this paper, a new method for the rolling is proposed and examined to avoid both errors. In the method, screws or cams with sufficiently high rigidity are used for a working apparatus. At first the some amount of displacement between workpiece and tool is forced corresponding to the stock allowance. Then, the displacement keeps constant during rolling. Experiments show that the concaving and the plastic deflection are successfully reduced. As the results both contact stress and difference of angular velocity between tool and workpiece are kept constant in rolling process. The accuracy of tooth profile reaches to JIS 0 Class in the experiments.
