Abstract
There are innumerable solutions when the pitch surface of hypoid gear is solved from requirement of two cones. The pitch angle is decided as the tooth lengthwise curvature is corresponding to the cutter radius by the Gleason method. In this study, using the new tooth geometry, the new design method which can optimize the contact ratio is proposed. The effectiveness of the optimum design method is confirmed by measuring transmission errors. A gear design example of reducing spiral angle is shown.
