【正文】 ，每一個部件都應(yīng)該符合相應(yīng)規(guī)格，只有每一個器件都是合格的才能保證車的質(zhì)量。質(zhì)量檢驗就必不可少，似乎我們沒有看到專門的檢驗儀器，我想，如果一個器件要經(jīng)過好幾個加工步驟，那最好還是先檢驗的好。我們還沒有上工程訓(xùn)練，到那時我們就可以真的親自體驗一下機(jī)器了。后來我們參觀了焊接車間，映入眼簾的就是大家都在燒電焊，刺眼的光，刺激的氣味，讓人不禁擔(dān)心這些電焊工人的身體健康，入口處雖然有必須戴口罩，頭罩，耳塞什么的，但似乎還是有些工人沒有戴。每間廠房墻壁上的橫幅就特別顯眼，我現(xiàn)在忘記了是什么，應(yīng)該每個工廠都會有自己的一些口號，目標(biāo)，理念。我們只是迅速的走完，大致了解了焊接的情況，還有邊加工，邊降溫是怎么做到的，等等。整理，整頓，清掃，清潔，素養(yǎng)。在第一個制件車間和這個焊接車間，我想我們已經(jīng)能體會這五個詞意味著什么，當(dāng)你看到工人嚴(yán)肅、專注的表情，不得不肅然起敬，這些生產(chǎn)一線上的員工們，對于這個汽車廠，他們才是寶?。〈碳の掖竽X的不是這些，而是一個很簡單的軌道，在車間之間，為了方便已經(jīng)大致成型的汽車而建的。我原本以為，安裝固定的軌道就可以了，為什么要可以滑動到，但當(dāng)我們親眼看到工人是怎樣通過滑道，輕松地將車從一個車間運到下一個車間，我瞬時明白了，有了這個轉(zhuǎn)運通道就不必按照固定的模式而有了更多的靈活性。霎時覺得自己好傻，頓時感受到人的智慧的無窮，相信車間還可以改裝的更好。能合理的計劃每輛車的加工流程。最后就參觀的總裝車間，安裝上方向盤，座椅，發(fā)動機(jī)等等，一步一步，看著一輛車就這么在我們眼前造好了，感覺很興奮。還有沖壓車間，和專門安放外購的發(fā)動機(jī)的車間以及研發(fā)試驗車間我們沒有參觀。這次最大的感觸就是“紙上得來終覺淺，絕知此事要躬行”。實踐出真知，先掌握知識，在用之于實踐，知識就升華了。最后，要感謝給我們這次實習(xí)機(jī)會的廠商，以及給我?guī)椭睦蠋熀屯瑢W(xué)們！第二篇：機(jī)械設(shè)計與制造英文翻譯外文翻譯How to extend the service life of bearing Nature39。s harsh working conditions can lead to the failure of bearing, but if you follow some simple rules, opportunities for normal operation of the bearing can be the using process of bearing,extreme neglect in a bearing leads to overheating and possibly seizure or, at worst, an even a failed bearing leaves clues as to what went a little detective work, action can be taken to avoid a repeat of the reasons for bearing failure, but mon is incorrect use of improper use, pollution, lubricants, loading and unloading or handling damage and installation error, problem is often not difficult to diagnose, because of a failed bearing usually leaving the slightest trace what went ，while a postmortem yields good information，it is better to avoid the process altogether by specifying the bearing correctly in The first place．To do this，it is useful to review the manufacturers sizing guidelines and operating characteristics for the selected important is the research requirement of noise, torque, beating, and possible exposure to pollutants, hostile liquid, and extreme can provide further clues bearing is suitable for this failure reasonenvironmental a light preload on the bearing helps keep the balls and raceway in tight also helps prevent false brinelling during can be caused by a lack of internal clearance, improper lubrication, or excessive seizing, excessive, friction and heat softens the bearing bearings often change color，usually to blueblack or straw colored．Friction also causes stress in the retainer，which can break and hasten bearing failure．Premature material fatigue is caused by a high load or excessive preload．When these conditions are unavoidable，bearing life should be carefully calculated so that a maintenance scheme can be worked out．Another solution for fighting premature fatigue is changing material．When standard bearing materials，such as 440C or SAE 52100，do not guarantee sufficient life，specialty materials can be addition，when the problem is traced back to excessive loading，a higher capacity bear
