輸送機機械零件失效

輸送機機械零(ling)件失效

    作為一家(jia)(jia)專(zhuan)業的輸送機生產廠家(jia)(jia)，今天為大(da)家(jia)(jia)分(fen)享的是關于成都凱(kai)瑞特輸送機械制造(zao)有限(xian)公司生產(chan)的四川輸送機機(ji)械零(ling)件(jian)失效的相關知識(shi)：

    關于四(si)川(chuan)輸送機機械(xie)零件(jian)的(de)工(gong)作能力和計(ji)算準(zhun)則，機械(xie)零件(jian)喪(sang)失(shi)工(gong)作能力或達不(bu)(bu)到(dao)設(she)計(ji)要(yao)(yao)求性(xing)能時，稱為失(shi)效。失(shi)效并不(bu)(bu)單(dan)純意味(wei)著破壞。常見(jian)的(de)失(shi)效形(xing)式(shi)有(you)：因強(qiang)度(du)(du)不(bu)(bu)足而斷裂(lie)；過大的(de)彈性(xing)變形(xing)或塑性(xing)變形(xing)；摩擦表面的(de)過度(du)(du)磨損、打滑或過熱；聯(lian)接松動；壓(ya)力容器、管道等的(de)泄漏(lou)；運動精度(du)(du)達不(bu)(bu)到(dao)要(yao)(yao)求等。

    同(tong)一種零件(jian)發生失效(xiao)(xiao)的(de)(de)形(xing)式(shi)(shi)可(ke)(ke)能(neng)(neng)有(you)數(shu)種。例如齒(chi)(chi)輪(lun)的(de)(de)失效(xiao)(xiao)形(xing)式(shi)(shi)有(you)：1）齒(chi)(chi)面(mian)(mian)(mian)粘著(zhu)磨(mo)損(sun)和(he)膠(jiao)合、磨(mo)粒磨(mo)損(sun)；2）齒(chi)(chi)面(mian)(mian)(mian)疲勞點蝕和(he)剝落；3）輪(lun)齒(chi)(chi)疲勞折斷和(he)過載折斷；4）齒(chi)(chi)面(mian)(mian)(mian)或齒(chi)(chi)體(ti)塑性(xing)變(bian)形(xing)；5）齒(chi)(chi)輪(lun)其他部分的(de)(de)破壞等。在(zai)各種失效(xiao)(xiao)中，其主(zhu)要(yao)的(de)(de)失效(xiao)(xiao)形(xing)式(shi)(shi)將由齒(chi)(chi)輪(lun)的(de)(de)材(cai)料、具體(ti)結構(gou)和(he)工(gong)作(zuo)條件(jian)等決定。在(zai)多(duo)塵粉下工(gong)作(zuo)的(de)(de)開式(shi)(shi)齒(chi)(chi)輪(lun)傳(chuan)動，齒(chi)(chi)面(mian)(mian)(mian)磨(mo)粒磨(mo)損(sun)可(ke)(ke)能(neng)(neng)是主(zhu)要(yao)失效(xiao)(xiao)形(xing)式(shi)(shi)；潤滑良好的(de)(de)閉式(shi)(shi)齒(chi)(chi)輪(lun)傳(chuan)動，疲勞點蝕可(ke)(ke)能(neng)(neng)是主(zhu)要(yao)失效(xiao)(xiao)形(xing)式(shi)(shi)。
