The effect of tooth root transition surface on bending strength of orthogonal face gear
摘要
Abstract
To analyze the bending strength of orthogonal face gear effectively,the tooth surface equation and deden-dum transition curve surface equation on orthogonal face gear were deduced. The whole tooth profile of the orthogo-nal face gear was established,and two kinds of 3D entity models of orthogonal face gear with the whole tooth profile were generated by using Pro/Engineer software. Based on the theory of internally tangent parabola,the position of the maximum bending stress of the orthogonal face gear was in the upper half portion of the tooth surface along the tooth height than at the dedendum. Analyses of the bending strength of the three-tooth models of two kinds of face gear cut by slotting cutter from rounded corner and sharp corner at the addendum were carried out using ANSYS software. The tooth root transition curve surface cut by slotting cutter from rounded corner at the addendum im-proved the bending strength of the orthogonal face gear.关键词
