ESTABLISHING GEAR TOOTH SURFACE GEOMETRY AND NORMAL DEVIATION - PART II - BEVEL GEARS

In this part, the concept of enveloping tangent planes dealing with ge ar geometry and normal deviations is applied to bevel gears. Exact sph erical involute is established by the procedure outlined in this paper . Straight tooth and spiral tooth bevel gears are considered in this p aper. The method of determining the normal deviation from the idealize d surface and the validation of the method are reported here. Effectiv eness of the proposed method for obtaining normal deviation is establi shed by considering spiral bevel gear geometry based on circular are. (C) 1998 Elsevier Science Ltd.
