Abstract : A new method for generation of spiral bevel gears is proposed. The main features of this method are as follows: (i) the gear tooth surfaces are conjugated and can transform rotation with zero transmission errors; (ii) the tooth bearing contact is localized; (iii) the center of the instantaneous contact ellipse moves in a plane that has a fixed orientation; (iv) the contact normal performs in the process of meshing a parallel motion; (v) the motion of the contact ellipse provides improved conditions of lubrication; and (vi) the gears can be manufactured by use of Gleason's equipment.
