style="text-indent:25px">起重機(jī)用鋼絲繩內(nèi)部磨損在使用過(guò)程中，由于鋼絲繩的彎曲使內(nèi)部各根細(xì)鋼絲相互作用產(chǎn)生滑移，股與股之間接觸應(yīng)力增大，相鄰股間的鋼絲產(chǎn)生局部壓痕深凹，當(dāng)反復(fù)循環(huán)拉伸彎曲時(shí)在深凹處則產(chǎn)生應(yīng)力集中而折斷，構(gòu)成了內(nèi)部磨損。通常細(xì)鋼絲表面的壓力與鋼絲繩的壓力成正比，在張力相同情況下由于受壓面積不同，單位面積承受的壓力也不同。從表面受壓磨損來(lái)看，鋼絲繩采用線接觸比采用點(diǎn)接觸較為有利，采用面接觸比采用線接觸更有利，因此選擇線接觸或者面接觸類(lèi)型的鋼絲繩是減少內(nèi)部磨損的有效途徑。此外鋼絲繩的彎曲程度、運(yùn)動(dòng)速度對(duì)其內(nèi)部磨損均有影響。</p><p
