機械零件設計（英文版）（原書第8版）縮編版

內容簡介

本教材縮編自M.F.Spotts，T.E.Shoupand L.E.Hornberger編寫的《Design of Machine Elements》（8fhEdition）。該書內容背罪豐富，大部挨去院分內容適合我國機械類本科生的教學要求。原教材共15章，不僅包括典型機械零部件的設計方法，而且匪肯再槳還包括工程力學、工程材料、形狀綜合原理和塑膠零件的設計等內容。為和我國目前高校機械基礎課程體系中機械設計課程的內容府雄宙相銜接，以便於各類讀者使用，編者對教材進行了重新組織和縮編。現包括9章內容，包括機械設計概論、基本應力分析和失效理論、軸的設計、彈簧、螺栓連線和螺旋傳動、帶傳動、離合器、制動器和鏈傳動、潤滑、滾動軸承、直齒圓柱齒輪、斜齒輪、錐齒輪和蝸桿傳動。從刪減的內容看，其內容或是與我承棵去享們的課程關係不大，或是在其他課程里已經學過。對於原書中豐富的習題，根據保留的基本內容進行了相應的刪減。另外，原教材為讀去糠烏者提供了一些基本的工程力學計算、典型零部件的設計程式。為與紙質教材相關內容相一致，沒有改變原程式中的模組編號。

本教材頁判試可以作為英文或雙語教學用機械設計課程的教材，也可供機械工程專業本科生、研究生或其他從事機械設計工作的專業人員參考。
