碩士 === 逢甲大學 === 機械工程學所 === 99 === Abstract Gear train which has the advantage of high precision, good efficiency, and relative compact in size is the most important component for motion and power transmission. A helical gear train used in a heavy duty hoist has been modeled dynamically in this thesis. Structural analyses for both helical gear train and transmission box have been performed. A 3-D solid model of integrated hoist transmission is built by using CAD software SolidWorks®. Then, dynamic analysis software MSC.ADAMS® is employed to analyze the relationship between loads and acceleration of helical gear train. Also the reaction forces of bearings are analyzed by ADAMS. By knowing the relationship between loads and acceleration of helical gear train, finite element software LS-DYNA® is employed to analyze the dynamical structural strength of helical gear train. Finally the ANSYS Workbench® is employed to proceeding structural analysis of the transmission box. The maximum von Mises stress and the maximum deformation of the hoist transmission box is calculated. The technique of Computer Aided Engineering is applied to analyze the transmission a heavy duty hoist and the results may be provided as references for hoist design improvement.
