機械設計:第4版(簡體書)

本書是美國Robert L. Mott教授所著Machine Elements in Mechanical Design（Fourth Edition，2004）的縮編版。縮編者在保持原書特色和風格的前提下，根據我國機械設計課程的教學要求，刪去了原書中與我國其他先修課程重復的部分內容，將原書23章縮編為16章，并將計量單位轉換為公制。縮編后的內容包括：機械設計概論，帶傳動與鏈傳動，齒輪傳動與蝸桿傳動，軸，軸聯接件（鍵、聯軸器、密封），滾動軸承，滑動軸承，緊固件，彈簧，機座，離合器與制動器，設計大作業等。
本書可作為高等學校工科機械類專業機械設計課程的雙語教學教材，也可供從事機械專業的教師、研究生或工程技術人員參考。
