dc.description.abstract | 凸輪機構因其運動穩定性和傳動效率而被廣泛應用於各種機構。其中,壓力角在設計凸輪機構時扮演著重要角色,過大的壓力角會導致凸輪與從動件卡死、過大的接觸力以及傳動效率降低等問題。本論文旨在解決上述問題,故提出一種帶有對稱偏位滾子的定徑凸輪機構。首先,本文提供一種合成該凸輪輪廓的解析法,並討論其設計限制。接著證明本類型從動件只需單片凸輪即可驅動,且同時進行力學分析以證明此凸輪機構相對於傳統的定徑凸輪機構具有更好的傳力效率。最後,綜合上述設計流程,本文將運用最佳化方法取得適當的設計參數,進而得到較小的基圓半徑與壓力角。 | zh_TW |
dc.description.abstract | Cam mechanism is commonly used in a wide range of machinery due to its stability and efficiency. Pressure angle plays an important role when designing the cam mechanism. A high-pressure angle could cause problems such as a jamming effect or stuck, higher contact force, and lower transmission efficiency. However, a lower pressure angle leads to a larger radius of the base circle which increased the size of the cam mechanism. This thesis aims to solve these problems by proposing a modified design of the constant diameter cam mechanism equipped with symmetrical offset rollers. Furthermore, this thesis provides an analytical approach for the profile synthesis of such a cam mechanism. Besides, its design limitations are also discussed. It is also proved that only one profile is required to positively drive its follower equipped with a set of symmetrical offset rollers. Force analysis is also conducted to demonstrate a better force transmission efficiency of such a cam mechanism over a conventional constant diameter one. At last, an optimization procedure is applied to obtain a compact design with a smaller base circle and lower pressure angle within an allowed range. | en |
