【正文】 只有每一個(gè)器件都是合格的才能保證車的質(zhì)量。我們還沒(méi)有上工程訓(xùn)練，到那時(shí)我們就可以真的親自體驗(yàn)一下機(jī)器了。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(gè)工廠都會(huì)有自己的一些口號(hào)，目標(biāo)，理念。整理，整頓，清掃，清潔，素養(yǎng)。我原本以為，安裝固定的軌道就可以了，為什么要可以滑動(dòng)到，但當(dāng)我們親眼看到工人是怎樣通過(guò)滑道，輕松地將車從一個(gè)車間運(yùn)到下一個(gè)車間，我瞬時(shí)明白了，有了這個(gè)轉(zhuǎn)運(yùn)通道就不必按照固定的模式而有了更多的靈活性。能合理的計(jì)劃每輛車的加工流程。還有沖壓車間，和專門安放外購(gòu)的發(fā)動(dòng)機(jī)的車間以及研發(fā)試驗(yàn)車間我們沒(méi)有參觀。實(shí)踐出真知，先掌握知識(shí)，在用之于實(shí)踐，知識(shí)就升華了。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 bearing or different configuration may be used．Creep is less mon than premature fatigue．In bearings．it is caused by excessive clearance between bore and shaft that allows the bore to rotate on the shaft．Creep can be expensive because it causes damage to other ponents in addition to the bearing．0ther more likely creep indicators are scratches，scuff marks，or discoloration to shaft and bore．To prevent creep damag
