碩士 === 國立彰化師範大學 === 車輛科技研究所 === 106 === In this study, the conical tooth is used for the spherical gear with double degree of freedom, and bulid the imaginary rack cutter with variable modulus discrete conical teeth. Then create the discrete ring involute teeth spherical gear pair with a double degree of freedom. The computer aided computing software is used to investigate the contact characteristics of spherical gear. Mathematica software package is used to design the mathematical model of imaginary rack cutter with variable modulus discrete conical teeth at first. Then determine the relationship of coordinate system between the generating and generated surface. Next, the surface family equation will be solved by homogeneous coordinate transformation matrix. Then find the Equation of meshing. The mathematic model of spherical gear pair with double degree can be created. The mathematical model of spherical gear pair with double degree are investigated in several cases about the misalignment of the gear pair.ANSYS-Workbench software package and Tooth Contact Analysis (TCA) method are used to analyzing the contact stress of gear pair in different condition while the gear pair is working
