【正文】 movement and momentum, and the scope of power, transmission efficient transmission accurately, long using life, such as safe and reliable character. Power output by electric motors through slow down transmission system to import power to the executive body. As the system make rotation movement, The steel cutting machine needs the back and forth straight line sport ,in order to achieve this transformation, we can use c slidercrank institutions or gear and rack. I decided to consider realistic conditions using slidercrank as the executing machinery. Key words ： cutting architectural reinforcing steel dar gear slidercrank 臥式鋼筋切斷機設(shè)計 目 錄 中文摘要 ……………………………………………………………………… .1 英文摘要 ……………………………………………………………………… .2 引言 ……………………………………………………………………………..3 概述 ..................................................................................................................................1 題目的選取 ......................................................................................................................1 鋼筋切斷機的原理 ..........................................................................................................1 第 2 章 電機選擇 ........................................................................................................................2 切斷鋼筋需用力計算 ......................................................................................................2 功率計算 ..........................................................................................................................3 第 3 章 傳動結(jié)構(gòu)設(shè)計 ................................................................................................................5 基本傳動數(shù)據(jù)計算 ..........................................................................................................5 分配傳動比 .....................................................................................................................5 計算機構(gòu)各軸的運動及動力參數(shù) ........................................................................ 5 帶傳動設(shè)計 .......................................................................................................................6 帶型的確定 .....................................................................................................................6 帶輪基準(zhǔn)直徑 .................................................................................................................6 帶速的確定 .....................................................................................................................6 中心距、帶長及包角的確定 .........................................................................................6 確定帶的根數(shù) .................................................................................................................7 張緊力 ............................................................................................................................ 7 作用在軸上的載荷 .........................................................................................................7 帶輪結(jié)構(gòu)與尺寸見零件圖 .............................................................................................7 齒輪傳動設(shè)計 ...................................................................................................................8 第一級齒輪傳動設(shè)計 ......................................................................................................8 輪傳動設(shè)計 .....................................................................................................12 軸的校核 ..........................................................................................................................15 .....................................................................................................................15 .....................................................................................................................19 平 鍵的校核 .......................................................................................................................22 軸承的校核 ...................................................................................................................23 選軸承型號 .................................................................................................................23 .........................................................................................................................24 第 4章 總結(jié) ..............................................................................................................................27 參考文 獻(xiàn) ...................................................................................................................................28 致謝 .............................................................................
