Exploring Parametric Modeling and Time-varying Mesh Stiffness of Face Gear with Curved Tooth
摘要
Abstract
A small module face gear with curved tooth and an involute cylindrical worm transmission system have been studied with the finite element analysis.The calculation models of time-varying mesh stiffness and stress of face gear with curved tooth are established.Firstly,some existing mesh stiffness calculation methods are introduced,and their disadvantages are analyzed.Based on the gear geometry and the gear formation theory,this paper derives the mathematical models for the involute cylindrical worm and the face gear with curved tooth and obtains the discrete coordinates on the tooth surface.On this basis,the paper establishes the geometrical model and the assembly model and then develops the model of face gear with five teeth.Then it elaborates the time-varying mesh stiffness calculation method based on the finite element analysis.The accuracy of this method is verified with an example of straight tooth column gear.Through the contrast with available literatures,the calculation method in this paper is checked.Finally,the finite element model of the face gear with curved tooth is created with the ANSYS software.Then the paper applies the finite element model to analyzing the gears in several different meshing positions during the transmission.关键词
