下面凸輪軸批發，凸輪軸廠家以及凸輪軸品牌公司來講講汽車凸輪軸的聲響有哪些現象？

    1、這種響聲是(shi)有節奏的斷續響，聲音比氣門挺桿響得(de)鈍重。在發(fa)動機(ji)中速運轉時(shi)(shi)(shi)，響聲比較(jiao)明顯；怠速時(shi)(shi)(shi)也(ye)能聽到；高速時(shi)(shi)(shi)一(yi)般(ban)消失(shi)，也(ye)有時(shi)(shi)(shi)變得(de)雜亂。在發(fa)響的同時(shi)(shi)(shi)，凸輪軸(zhou)軸(zhou)承附(fu)近常常有振動。

    2、原因凸(tu)(tu)(tu)(tu)輪(lun)軸(zhou)和(he)軸(zhou)承(cheng)(cheng)(cheng)配(pei)合松(song)曠或凸(tu)(tu)(tu)(tu)輪(lun)軸(zhou)彎曲，當凸(tu)(tu)(tu)(tu)輪(lun)軸(zhou)轉動時，軸(zhou)頸和(he)軸(zhou)承(cheng)(cheng)(cheng)相互撞(zhuang)擊而發出響聲；凸(tu)(tu)(tu)(tu)輪(lun)軸(zhou)與軸(zhou)承(cheng)(cheng)(cheng)配(pei)合松(song)曠，間隙超限(xian)，軸(zhou)承(cheng)(cheng)(cheng)外頸與座(zuo)孔(kong)配(pei)合過松(song)，使(shi)軸(zhou)承(cheng)(cheng)(cheng)在座(zuo)孔(kong)內轉動而燒損；新(xin)換軸(zhou)承(cheng)(cheng)(cheng)未經(jing)鏗削或刮削精(jing)度(du)不(bu)夠，使(shi)軸(zhou)承(cheng)(cheng)(cheng)加(jia)(jia)速磨(mo)損，形成早期松(song)曠；凸(tu)(tu)(tu)(tu)輪(lun)軸(zhou)彎曲變形，凸(tu)(tu)(tu)(tu)輪(lun)軸(zhou)受到(dao)摔碰和(he)擠壓、修磨(mo)凸(tu)(tu)(tu)(tu)輪(lun)軸(zhou)時裝卡不(bu)當；更(geng)換軸(zhou)承(cheng)(cheng)(cheng)后，軸(zhou)承(cheng)(cheng)(cheng)加(jia)(jia)工(gong)精(jing)度(du)低。

    3、診(zhen)斷方(fang)法此響(xiang)(xiang)聲(sheng)“斷火”試(shi)驗無反應。當發(fa)動(dong)機(ji)運轉時(shi)，傾聽發(fa)響(xiang)(xiang)部位。如果聲(sheng)音(yin)是(shi)在凸輪(lun)軸一側，可緩緩變(bian)換節氣門試(shi)驗。怠速(su)時(shi)響(xiang)(xiang)聲(sheng)較清晰，中速(su)時(shi)明顯(xian)，高速(su)時(shi)聲(sheng)音(yin)變(bian)得雜亂或減弱以至消失(shi)，則可能是(shi)這種(zhong)響(xiang)(xiang)聲(sheng)。
