凸輪傳動(dòng)機(jī)構(gòu)的活塞式引擎為何沒(méi)能廣泛應(yīng)用？

加工成本應(yīng)該不會(huì)低，組裝維修要難些。占用空間大。
第一種：四缸在同一垂直面上，潤(rùn)滑不一致，散熱不一致 ...

謝謝！{:soso_e179:}

論壇有高手，看過(guò)之后很受啟發(fā)。

另外這個(gè)是高副配合，比曲軸瓦壽命上差多了。

設(shè)計(jì)整車(chē)時(shí)不好放置，裝配時(shí)還要轉(zhuǎn)來(lái)轉(zhuǎn)去

就是生產(chǎn)成本高，沒(méi)有別的了，車(chē)機(jī)，最終統(tǒng)一到直列與V機(jī)，歷史的選擇，連水平對(duì)置都屬于邊緣機(jī)，盡管效果比 ...

活塞發(fā)動(dòng)機(jī)供坦克用, 最新大多是水平對(duì)向, 以減低坦克高度

很有創(chuàng)意的結(jié)構(gòu)，不過(guò)就如圖一的，如果活塞上的凸輪磨損后會(huì)不會(huì)出現(xiàn)問(wèn)題。如果是用于壓縮機(jī)的話不知道效果如何啊。

謝謝！這種凸輪驅(qū)動(dòng)機(jī)構(gòu)在壓縮機(jī)、液壓泵等行業(yè)應(yīng)用較熱機(jī)行業(yè)多。{:soso_e100:}

Left: The Fairchild-Caminez Cam Engine: 1926.

The Fairchild-Caminez 447 engine was a four-cylinder air-cooled radialintended for aircraft useage. It was designed by Harold Caminez, who had previouslyworked in the Engine Design Section of the US Army Air Service. The pistonsacted on a leminiscate-shape cam, which made only one revolution for every twopiston cycles, so for the same number of power impulses the engine ran at halfspeed. The pistons were connected by steel links to keep them pressed againstthe cam; the cylinder were steel with aluminium heads.

二戰(zhàn)時(shí)飛機(jī)發(fā)動(dòng)機(jī)是這樣的嗎？

機(jī)加跟裝配的話，有點(diǎn)難度
