Abstract:

The mathematical equations of the elliptical straight tooth wheels, which are an important member of the non-circular tooth wheels, are prepared in the first stage of the study. In the second phase, the computer software in the AutoLISP programming language environment has been developed to solve the equations within the cycle and to model 2-D images of the desired number of teeth and the module of the elliptical teeth. With the developed package program in the AutoCAD environment, the 2-D field is obtained by the module 2 and the number of teeth is 32 and the ANSYS program is used to determine the natural frequencies and modes by the method of the elliptical tooth wheel end elements. ABAQUS software has been used to create the full 3-D model of the elliptical tooth wheel. The natural vibration characteristics of the elliptical tooth wheel, the types of vibration and the natural frequencies of the elliptical tooth wheel have been identified. This method can be used for engineering applications and dynamic analyses of elliptical tooth wheels. This method can be used to determine how a structure responds to any type of dynamic load to determine the vibration feature and to make a more practical and low-cost analysis before making any design or application. The results of the analyses were found that unregular movement could be used as a machine element where it could be achieved without the need to stop completely.
