摘 要當(dāng)前中國老齡化社會(huì)的壓力越來越大。項(xiàng)目針對老齡化社會(huì)護(hù)理人員多為女性且老式樓房沒有電梯的特點(diǎn)，設(shè)計(jì)具備爬樓梯功能的電動(dòng)輪椅，從而有效提高老年人的生活質(zhì)量。本次設(shè)計(jì)主要針對一種三星輪式電動(dòng)爬樓梯輪椅的結(jié)構(gòu)進(jìn)行設(shè)計(jì)。首先，通過對電動(dòng)爬樓輪椅結(jié)構(gòu)及原理進(jìn)行分析，在此分析基礎(chǔ)上提出了總體結(jié)構(gòu)方案；接著，對主要技術(shù)參數(shù)進(jìn)行了計(jì)算選擇；然后，對各主要零部件進(jìn)行了設(shè)計(jì)與校核；最后，通過 AutoCAD 制圖軟件繪制了電動(dòng)爬樓輪椅裝配圖及主要零部件圖。整個(gè)設(shè)計(jì)過程中包括其中的數(shù)據(jù)計(jì)算、傳動(dòng)系統(tǒng)設(shè)計(jì)、電機(jī)等外購件選型、應(yīng)用環(huán)境、維護(hù)保養(yǎng)等方面進(jìn)行系統(tǒng)設(shè)計(jì)。通過本次設(shè)計(jì)，鞏固了大學(xué)所學(xué)專業(yè)知識(shí)，如：機(jī)械原理、機(jī)械設(shè)計(jì)、材料力學(xué)、公差與互換性理論、機(jī)械制圖等；掌握了普通機(jī)械產(chǎn)品的設(shè)計(jì)方法并能夠熟練使用AutoCAD制圖軟件，對今后的工作于生活具有極大意義。關(guān)鍵詞：電動(dòng)；爬樓；輪椅；行星輪AbstractWith the advent of an aging society and increase number in the disabilities persons ,the wheelchairs play a more important role in the living, the staircase can be seen everywhere in life limits the use of an ordinary wheelchair, the purpose of this study is to design affordable and reasonable ,safe and reliable performance . When walking on level ground as an ordinary electric wheelchair ,and in others on the stairs like a simple auxiliary function of electric stairs. Climbing stairs electric wheelchair is one kind of the service robots ,and it is the elderly and disabled peoples’ indispensable rehabilitation and transport ,To use a wheelchair old people and disabled people can physical exercise and participate in social activities .Considering the convenience of the elderly and the disabled peoples’ traveling ,researching and developing a climb stairs function wheelchair has the significant practical significance.The design will be up and down the stairs to the electric wheelchair design, to meet the legs disabled and elderly automatic staircase function. From the main design, structure design, including the data computation, the transmission system design, the motor and purchased parts selection, application, maintenance and other aspects of system design. And draw the electric wheelchair2D assembly drawing and parts drawing.Key words: Electric wheelchair Star wheel climbing device Structure design 目 錄摘 要 IAbstract II第 1 章 緒 論 .11.1 課題的研究背景及意義 .11.2 國內(nèi)外研究現(xiàn)狀 .11.2.1 履帶式 .11.2.2 星輪式 .21.2.3 腿足式 .21.2.4 復(fù)合式 .3第 2 章 總 體 方 案 設(shè) 計(jì) 52.1 總體類型選擇 .52.1.1 設(shè)計(jì)要求 .52.1.2 類型選擇 .52.2 總體結(jié)構(gòu)設(shè)計(jì) 62.3 行星輪機(jī)構(gòu)設(shè)計(jì) .72.3.1 行星輪總體結(jié)構(gòu)概述 .72.3.2 行星輪架的中心距 .72.3.3 小輪半徑 r 的范圍值 .8第 3 章 驅(qū) 動(dòng) 機(jī) 構(gòu) 設(shè) 計(jì) 103.1 動(dòng)力系統(tǒng)參數(shù)選擇 .103.2 驅(qū)動(dòng)電機(jī)選擇 .103.2.1 驅(qū)動(dòng)電機(jī)的類型選擇 .103.2.2 選擇驅(qū)動(dòng)電機(jī)的功率 .103.3 蓄電池選擇 .123.4 計(jì)算傳動(dòng)裝置的運(yùn)動(dòng)和動(dòng)力參數(shù) .133.4.1 各軸轉(zhuǎn)速 .133.4.2 各軸輸入功率 .133.4.3 各軸轉(zhuǎn)矩 .13第 4 章 主 要 零 件 設(shè) 計(jì) 計(jì) 算 144.1 齒輪傳動(dòng)設(shè)計(jì) .144.1.1 傳動(dòng)比計(jì)算 .144.1.2 齒輪模數(shù)與齒數(shù)計(jì)算 .144.1.3 載荷系數(shù)計(jì)算 .164.1.4 幾何尺寸計(jì)算 .184.2 鏈傳動(dòng)設(shè)計(jì) 184.2.1 鏈傳動(dòng)設(shè)計(jì)計(jì)算 .194.2.2 鏈輪結(jié)構(gòu)尺寸設(shè)計(jì) .214.3 軸及附件設(shè)計(jì) .214.3.1 計(jì)算各軸的強(qiáng)度 .214.3.2 軸的結(jié)構(gòu)設(shè)計(jì) .224.3.3 軸的強(qiáng)度校核 .23結(jié) 論 25參 考 文 獻(xiàn) .26致 謝 27
