小型手推式拖地機(jī)-智能拖地機(jī)機(jī)械結(jié)構(gòu)設(shè)計(jì)（帶CAD圖紙和三維及說(shuō)明書）,小型,手推式,拖地,智能,機(jī)械,結(jié)構(gòu)設(shè)計(jì),cad,圖紙,以及,三維,說(shuō)明書,仿單 摘 要 本設(shè)計(jì)設(shè)計(jì)了一個(gè)小型手推式拖地機(jī)，適用于樓道走廊，家庭等場(chǎng)所。拖地機(jī)首先由動(dòng)力裝置，傳動(dòng)裝置，拖地裝置組成。動(dòng)力裝置通過(guò)帶輪傳動(dòng)，使主軸Ⅰ旋轉(zhuǎn)，通過(guò)安放在主軸上的錐齒輪改變方向，帶動(dòng)帶輪傳動(dòng)，從而讓拖地機(jī)前面兩個(gè)拖地圓盤逆時(shí)針轉(zhuǎn)動(dòng)，進(jìn)行拖地工作。其次，通過(guò)裝在主軸Ⅰ一端的帶輪帶動(dòng)軸Ⅱ旋轉(zhuǎn)，安裝在軸Ⅱ上的滾刷機(jī)構(gòu)再次清理前面拖地圓盤工作過(guò)的地面，且把垃圾收集到后面的垃圾箱里。至此，完成所要求的功能和任務(wù)。 本畢業(yè)設(shè)計(jì)中，通過(guò)圖書館，互聯(lián)網(wǎng)查閱，搜集了大量的資料，對(duì)不同的設(shè)計(jì)結(jié)構(gòu)方案進(jìn)行了對(duì)比，分析并最終確定了一種比較理想的好的設(shè)計(jì)方案，然后根據(jù)已確定方案進(jìn)行機(jī)構(gòu)的設(shè)計(jì)計(jì)算，確定各個(gè)零部件尺寸和相應(yīng)型號(hào)，對(duì)其進(jìn)行校核以確保滿足設(shè)計(jì)要求。設(shè)計(jì)的零部件相對(duì)的比較簡(jiǎn)單，實(shí)用，且方便制造，所以其成本較低，是一種比較經(jīng)濟(jì)實(shí)惠的小型手推式拖地機(jī)。 關(guān)鍵詞：拖地機(jī)；成本。  Abstract The graduation project designed a small hand-push mopping machine for the corridor , home and other places. Mopping machine is made of the power device, transmission device, and mopping device . Power device makes Ⅰ spindle rotated by changing the direction of the spindle is mounted on a bevel gear device and drive pulley, so that the front of the machine’s two mop devices rotate counterclockwise, drag to work. Then,though Ⅰ spindle make Ⅱ spindle start to rotate, brush mechanism is mounted on the shaft Ⅱ again clean worked ground and collect the rubbsh.So the graduation project completes the required functions and tasks. Through libraries, Internet access, the graduation design collect a lot of information and compares different design projects.Finally determine a ideal project.According to the projiet,I collect different sizes of component and the make sure to meet the design requirements. The graduation design is simple, practical, and easy to manufacture, so the cost is affordable. Keywords : mopping machine ; costs. 目 錄 引言…………………………………………………………………………………………1 1 總體方案的設(shè)計(jì)………………………………………………………………………3 1.1 方案設(shè)計(jì)的技術(shù)要求…………………………………………………………………3 1.2 總體方案的確定………………………………………………………………………3 2 相關(guān)零件的計(jì)算……………………………………………………………………5 2.1 蓄電池的選擇…………………………………………………………………………5 2.1.1池蓄電分類…………………………………………………………………………5 2.1.2選用蓄電池型號(hào)……………………………………………………………………6 2.1.3蓄電池性能…………………………………………………………………………6 2.2 電動(dòng)機(jī)的選擇…………………………………………………………………………7 2.2.1電動(dòng)機(jī)選擇方法……………………………………………………………………7 2.2.2電動(dòng)機(jī)的種類和特性………………………………………………………………7 2.2.3齒輪減速電動(dòng)機(jī)的選………………………………………………………………7 2.2.4齒輪減速電動(dòng)機(jī)的分類和特點(diǎn)……………………………………………………8 2.2.5齒輪減速電動(dòng)機(jī)優(yōu)點(diǎn)………………………………………………………………8 2.3電動(dòng)機(jī)功率計(jì)算………………………………………………………………………9 3 拖地機(jī)結(jié)構(gòu)設(shè)計(jì)…………………………………………………………………10 3.1 傳動(dòng)比分配……………………………………………………………………………10 3.2 帶輪的結(jié)構(gòu)設(shè)計(jì)……………………………………………………………………10 3.2.1 電動(dòng)機(jī)和Ⅰ軸之間帶輪的設(shè)計(jì)計(jì)算………………………………………………10 3.2.2 軸Ⅰ軸Ⅱ之間帶輪的設(shè)計(jì)…………………………………………………………13 3.2.3軸Ⅲ和軸Ⅳ之間帶的設(shè)計(jì)計(jì)算（一）…………………………………………16 3.2.4 軸Ⅲ和軸Ⅳ之間帶的設(shè)計(jì)計(jì)算（二）………………………………………………19 3.3 錐齒輪的設(shè)計(jì)計(jì)算……………………………………………………………………22 3.3.1第一對(duì)直齒錐齒輪的設(shè)計(jì)計(jì)算……………………………………………………22 3.3.2第二對(duì)直齒錐齒輪的設(shè)計(jì)計(jì)算……………………………………………………26 3.4 主軸的設(shè)計(jì)計(jì)算……………………………………………………………………29 3.4.1主軸的結(jié)構(gòu)設(shè)計(jì)…………………………………………………………………29 3.4.2主軸的校核………………………………………………………………………30 3.4.3 鍵的選擇……………………………………………………………………………33 3.4.4鍵的校核……………………………………………………………………………33 3.5軸承的設(shè)計(jì)計(jì)算………………………………………………………………………34 3.5.1軸承的選擇…………………………………………………………………………34 3.5.2軸承的校核…………………………………………………………………………34 3.5.2軸Ⅱ軸承校核………………………………………………………………………35 3.5 車架的設(shè)計(jì)……………………………………………………………………………37 4 結(jié)論……………………………………………………………………………………39 謝 詞………………………………………………………………………………………41 參考文獻(xiàn)…………………………………………………………………………………42
