A new type of bevel gearing with spiral teeth formed by means of two alternate generating worms is presented. The toothing method by means of generating cutter head and the general sequence of gearing design are described. The stages of gearing design are considered - the choice of diagram parameters, the choice of generating parameters and the calculation of gear tooth geometry, calculation of virtual conjugate meshing, and synthesis of localized contact. Methods for selection the machine-tool meshing parameters for pinion and gear and a method for calculating the active acting line are proposed. The main properties of the gearing are determined, as well as the operational and production advantages of the new type of the gearing - the possibility of providing a higher overlap coefficient and smooth operation, the possibility of effective methods for contact localization control and the availability of tooth machining technology.
