擺動活塞式發(fā)動機的結(jié)構(gòu)設(shè)計,擺動,活塞,發(fā)動機,結(jié)構(gòu)設(shè)計 邵陽學(xué)院畢業(yè)設(shè)計（論文） 內(nèi)容提要 內(nèi)燃機的發(fā)明，帶動了汽車的發(fā)展，給世人在“行”上帶來極大的便利，使得窨距離縮小，人們的工作速度得以提高。內(nèi)燃機是發(fā)動機的一種。發(fā)動機是把某種形式的能轉(zhuǎn)變?yōu)闄C械能的機器。發(fā)動機是汽車、拖拉機、飛機和船舶等動力機械的動力之源，是它們的“心臟”，其性能是決定這些機器使用性能好壞的關(guān)鍵。往復(fù)式發(fā)動機由于受自身結(jié)構(gòu)的限制，已經(jīng)不太適用于高轉(zhuǎn)速、大功率的工作場合。 通過對往復(fù)式發(fā)動機與旋轉(zhuǎn)式發(fā)動機的結(jié)構(gòu)特點與工作原理進行對比分析后。作者試求設(shè)計一種能夠結(jié)合往復(fù)式發(fā)動機與旋轉(zhuǎn)式發(fā)動機特點于一身的新型發(fā)動機——擺動活塞式發(fā)動機。 首先，針對擺動活塞式發(fā)動機的工作原理進行設(shè)計與分析。這種新型發(fā)動機既具備傳統(tǒng)發(fā)動機的曲柄連桿機構(gòu)，又具備了旋轉(zhuǎn)式發(fā)動機的旋轉(zhuǎn)特性。它利用扇形活塞轉(zhuǎn)子在一定角度范圍內(nèi)旋轉(zhuǎn)的擺動，通過活塞銷帶動曲柄連桿機構(gòu)的運動，最終將力傳到曲軸上作為動力輸出。 其次，針對擺動活塞式發(fā)動機的總體結(jié)構(gòu)進行設(shè)計。即主要針對發(fā)動機的重要傳動機構(gòu)——曲柄連桿機構(gòu)進行結(jié)構(gòu)分析與設(shè)計，其中包括發(fā)動機氣缸、燃燒室、活塞連桿組以及曲軸等部件的結(jié)構(gòu)設(shè)計與分析。 最后，借鑒目前廣泛使用的發(fā)動機輔助機構(gòu)——冷卻系統(tǒng)與潤滑系統(tǒng)。對冷卻與潤滑系統(tǒng)的結(jié)構(gòu)及部件進行分析介紹，以致能充分完善發(fā)動機的總體結(jié)構(gòu)。 關(guān)鍵詞：發(fā)動機；擺動式發(fā)動機；掃氣作用；浮式連接；包瓦現(xiàn)象；平衡重 Content summary The internal combustion engine invention, has led the automobile development, on brings the enormous convenience for the common people in "the line", causes the basement distance to reduce, people's working speed can enhance. The internal combustion engine is the engine one kind. The engine is can transform some kind of form into the mechanical energy machine. The engine is power generator the and so on automobile, tractor, airplane and ships source of power, is they "the heart", its performance is decides these machine operational performance qualities the key. The reciprocation type engine as a result of own structure limit, not too is already suitable for the high rotational speed, the high efficiency work situation. Through carries on the contrast analysis after the reciprocation type engine and the rotary system engine unique feature and the principle of work. The author tries to ask to design one kind to be able to unify the reciprocation type engine and the rotary system engine characteristic——swings the piston engine in a body new engine. First, in view of swings the piston engine principle of work to carry on the design and the analysis. This kind of new engine both has the traditional engine crank link motion gear, and has had the rotary system engine turning performance. It uses the fan-shaped piston rotor in certain angle scope internal rotation swinging, through the piston pin impetus crank link motion gear movement, finally passes to the strength on the crank to take the dynamic output. Next, in view of swings the piston engine overall structure to carry on the design. Namely mainly aims at the engine the important transmission system ——crank link motion gear to carry on the structure analysis and the design, including part and so on engine cylinder, combustion chamber, piston linkage as well as crank structural design and analysis. Finally, model at present widespread use engine auxiliary body ——cooling system and lubrication system. To cools carries on the analysis introduction with the lubrication system structure and the part, so that can fully consummate the engine the overall structure.
