中文摘要
本研究乃是針對齒凸輪間歇運動機構之分析與運動曲線合成進行探討。齒凸輪機構之作動,是以溝槽凸輪產生搖臂行星齒輪的變轉速運動,以及行星齒輪系可產生運動線性疊加輸出之特性,藉此將輸入之等速旋轉運動轉換為輸出之間歇旋轉運動。本研究首先針對輸出之間歇運動曲線合成進行探討,應用有理式B仿線進行運動曲線合成,並藉此獲得運動特徵較佳之運動曲線,接著以剛體轉置法建立齒凸輪間歇運動機構之凸輪之幾何外型,並針對凸輪之壓力角、曲率半徑進行分析,最後針對齒凸輪機構進行剛體力學分析,作為判斷運動曲線合成良窳之基準。以上述之理論建立為基礎,本研究針對平盤式軋盒機紙張輸送系統所使用之齒凸輪間歇運動機構進行運動曲線合成,並進行凸輪幾何外型建立以及剛體力學分析,藉此提升紙張輸送系統之性能,作為本研究之驗證。
Abstract
The aim of the research is the analysis and motion curve synthesis for cam-gear intermittent mechanisms. Based on the grooved-cam-controlled motion of rocker planet gear and motion superposition of the planet gear trains, cam-gear intermittent mechanisms transfer continuous rotation to intermittent rotation. Interpolation of non-parametric rational B-splines motion curve is first introduced in this thesis, and it provides better motion characteristics. Based on rigid body transformation, the analytical grooved cam profile can be determined, and the pressure angle and radius of curvature can be calculated. By applying vector operation, rigid body dynamic analysis is also performed. An application example for cam-gear intermittent mechanisms used in the paper delivery system of the die cutting and creasing machine is served to support the content of this research and to improve the kinematic and dynamic characteristics of the paper delivery system.
