【正文】 The tactful of the cam form line is more good and vibration and voice of . engine are more small,Cam stalk with stand the contact of pillar more small in response to the dint,Lubricate characteristic more good, the . engine goes together with impact of annoy the organization to carry lotus and friction to wear away more with . engine constantly to agile turn, the high speed turn, high performance and high life span direction the development be more and more high to go together with the spirit cam request of stalk design and , the modern . engine goes together with spirit organization, mostly adopt several motive cams and n time the Xie wave cam or pound put a line these cam form line square distance not only pute plications, and with . engine structure the parameter be irrelevant and have of the n rank don39。t in a row lead not a few researchers carried on to a few abovementioned form line cams various excellent turn a design, it the plentiful full coefficient all could not reach , can39。t also adapt . engine high speed to turn and the request of high , the research submits a n rank to lead number continuous, from change to measure for the . engine main structure parameter, Chong spirit function good, vibrate small, the voice is low and design in brief new go together with spirit the cam form line square distance, is a very and important research topic.The cam organization is 1 kind that the engineering is convenient to carry out machine and automation to mainly drive with control acquire in the light work, spinning, food, medicine, printing, standard spare parts manufacturing, transportation etc. the realm the movement of the work machine extensively raising the quality and rate of production of to raise it to design level further in regard to research and expansion application of the assistance design of the exhibition calculator in analyzing the foundation of method order to adapt the demand of highspeed analysis and design of the cam organization, I carried on exterior an importation to each index number and the coefficient in trying the curve square distance of the cam design work efficiency and design to pute accuracy contact which returns a to output the data to each system and the cam in the meantime carried on a research, controled some and basic regulation, excellent to cam design started to turn to arrive good effect.KEY WORD Convex axle Deliver motive design目錄第一章 緒言 1第一節(jié) 凸輪軸的作用 1第二節(jié) 凸輪軸分類 1第二章 發(fā)動(dòng)機(jī)凸輪軸的配置 2第一節(jié) 凸輪軸成為發(fā)動(dòng)機(jī)的重要標(biāo)志 2第二節(jié) 凸輪軸配置 2第三章 設(shè)計(jì)論述 4第一節(jié) 優(yōu)化設(shè)計(jì) 4第二節(jié) 凸輪輪廓曲線的設(shè)計(jì) 4結(jié)束語(yǔ) 13謝辭 14參考文獻(xiàn) 15. . . . .第一章 緒言第一節(jié) 凸輪軸的作用凸輪軸是發(fā)動(dòng)機(jī)配氣機(jī)構(gòu)的一部分，專門負(fù)責(zé)驅(qū)動(dòng)氣門按時(shí)開啟和關(guān)閉，作用是保證發(fā)動(dòng)機(jī)在工作中定時(shí)為汽缸吸入新鮮的可燃混合氣，并及時(shí)將燃燒后的廢氣排出汽缸。凸輪軸直接通過(guò)搖臂驅(qū)動(dòng)氣門，很適用于高轉(zhuǎn)速的轎車發(fā)動(dòng)機(jī)，由于轉(zhuǎn)速較高，為保證進(jìn)排氣和傳動(dòng)效率、簡(jiǎn)化傳動(dòng)機(jī)構(gòu)、降低高轉(zhuǎn)速的
