手(shou)拉葫(hu)蘆(lu)俗稱葫(hu)蘆(lu)或倒鏈(lian)，齒輪作為手(shou)拉內部的重(zhong)要傳(chuan)動部件(jian)，手(shou)拉葫(hu)蘆(lu)保(bao)養(yang)記錄表(biao)，質量(liang)和噪音也是(shi)衡量(liang)一(yi)款產品的重(zhong)中之重(zhong)。

手(shou)(shou)拉葫蘆齒(chi)輪(lun)加工精(jing)度及(ji)輪(lun)齒(chi)剛度精(jing)度低、誤差大(da)，則(ze)嚙合沖(chong)擊大(da);輪(lun)齒(chi)剛度低，棗莊手(shou)(shou)拉葫蘆保養，受力后彈性(xing)變形大(da)，嚙合沖(chong)擊大(da);這些(xie)都(dou)會(hui)導致噪聲加大(da)，質(zhi)量(liang)下(xia)降。

        我們只有在(zai)提高齒(chi)輪(lun)剛度，可(ke)減小其彈性變形，手拉葫(hu)蘆保(bao)養注意什么，減小齒(chi)輪(lun)嚙合(he)沖擊力，是手拉葫(hu)蘆降噪(zao)的(de)有效(xiao)措(cuo)施。而(er)加大(da)齒(chi)輪(lun)模數(shu)， 能顯著增強輪(lun)齒(chi)剛度，簡單可(ke)行(xing)。做到面面俱(ju)到，增加了手拉葫(hu)蘆的(de)使用型并較少了齒(chi)輪(lun)的(de)噪(zao)音。

經上(shang)述情(qing)況我們在(zai)使用(yong)大(da)型(xing)起重裝卸用(yong)手拉(la)葫蘆時，能夠有效的減少作業時齒輪(lun)嚙合所產生的噪(zao)音。河北牧田(tian)所挑(tiao)選(xuan)的全是齒輪(lun)，手拉(la)葫蘆在(zai)剛度和(he)韌性上(shang)都有較大(da)的提(ti)高(gao)。增(zeng)加了使用(yong)周長。

在日常生產、操(cao)作等工(gong)程中(zhong)，我(wo)們(men)經常強(qiang)調(diao)要規避風險(xian)(xian)，遠(yuan)離(li)危(wei)險(xian)(xian)，要想做到(dao)這(zhe)些，需要了解手拉(la)葫(hu)蘆的危(wei)險(xian)(xian)源及(ji)使用(yong)要求
