That text precedes the total designs to the Rackandpinion steering. Suffering the dint analysis, and calibrate the tired strength of the machine with the bent and tired strength in root of tooth. This article revised the unreasonable data of the steering. With the design of the Rackandpinion steering, selects the related spare parts. Such as bolt, bearing...etc. and draw the diagrams of the related spare parts in manual. Drawing the 6 precise of spare parts diagrams and 1 precise of the assemble diagram of Rackandpinion steering.Key words: Rackandpinion steering, design and calculation目錄中文摘要 IAbstract II第一章 引言 1 1 1第二章 齒輪齒條轉(zhuǎn)向器設(shè)計(jì)方案選擇 3第三章 傳動(dòng)比的計(jì)算 6 汽車方向盤(轉(zhuǎn)向盤) 6 轉(zhuǎn)向阻力矩 6 6第四章 齒輪設(shè)計(jì) 8 齒輪參數(shù)的選擇[8] 8 齒輪幾何尺寸確定[2] 8 齒根彎曲疲勞強(qiáng)度計(jì)算[11] 材料及參數(shù)的選擇 9。 9 10第五章 齒條的設(shè)計(jì) 12[6] 12第六章 齒輪軸的設(shè)計(jì)[4] 13第七章 其他零件的選擇[6] 14設(shè)計(jì)工作總結(jié) 17參考文獻(xiàn) 18致 謝 19第一章 引言改革開放以來(lái),我國(guó)汽車工業(yè)發(fā)展迅猛。作為汽車關(guān)鍵部件之一的轉(zhuǎn)向系統(tǒng)也得到了相應(yīng)的發(fā)展,基本已形成了專業(yè)化、系列化生產(chǎn)的局面。有資料顯示,國(guó)外有很多國(guó)家的轉(zhuǎn)向器廠,都已發(fā)展成大規(guī)模生產(chǎn)的專業(yè)廠,年產(chǎn)超過(guò)百萬(wàn)臺(tái),壟斷了轉(zhuǎn)向器的生產(chǎn),并且銷售點(diǎn)遍布了全世界?! ?. 適應(yīng)汽車高速行駛的需要 從操縱輕便性、
