齒(chi)(chi)輪(lun)滾(gun)(gun)(gun)刀(dao)(dao)(dao)是根據螺旋齒(chi)(chi)輪(lun)嚙合(he)工作(zuo)原理和加工直齒(chi)(chi)和斜齒(chi)(chi)圓(yuan)柱齒(chi)(chi)輪(lun)的(de)(de)(de)(de)選擇工具(ju)。相當(dang)于(yu)沒(mei)有(you)齒(chi)(chi)數少、螺旋角(jiao)大(da)的(de)(de)(de)(de)斜齒(chi)(chi)輪(lun)呈(cheng)蝸桿狀。合(he)理有(you)效地使(shi)用(yong)不同(tong)的(de)(de)(de)(de)齒(chi)(chi)輪(lun)滾(gun)(gun)(gun)刀(dao)(dao)(dao)。1、正確安(an)裝(zhuang)：滾(gun)(gun)(gun)刀(dao)(dao)(dao)安(an)裝(zhuang)在(zai)滾(gun)(gun)(gun)齒(chi)(chi)機主軸(zhou)上，滾(gun)(gun)(gun)刀(dao)(dao)(dao)兩端凸起的(de)(de)(de)(de)徑(jing)向圓(yuan)跳動不超(chao)過0.005mm。及時(shi)跳躍：滾(gun)(gun)(gun)刀(dao)(dao)(dao)滾(gun)(gun)(gun)動齒(chi)(chi)時(shi)，通常只使(shi)用(yong)中間的(de)(de)(de)(de)幾個(ge)齒(chi)(chi)來切割工件，因此這些齒(chi)(chi)很容(rong)易磨(mo)(mo)(mo)損。為了使(shi)每個(ge)刀(dao)(dao)(dao)齒(chi)(chi)均勻(yun)磨(mo)(mo)(mo)損，延長滾(gun)(gun)(gun)刀(dao)(dao)(dao)的(de)(de)(de)(de)使(shi)用(yong)壽命(ming)，在(zai)滾(gun)(gun)(gun)刀(dao)(dao)(dao)切割一(yi)定數量的(de)(de)(de)(de)齒(chi)(chi)輪(lun)后(hou)，可以(yi)沿滾(gun)(gun)(gun)刀(dao)(dao)(dao)軸(zhou)手動或電動移動一(yi)個(ge)或多個(ge)齒(chi)(chi)距，以(yi)提高(gao)滾(gun)(gun)(gun)刀(dao)(dao)(dao)的(de)(de)(de)(de)使(shi)用(yong)壽命(ming)。及時(shi)重磨(mo)(mo)(mo)：發現齒(chi)(chi)表面(mian)(mian)粗(cu)糙度大(da)于(yu)ra3.2.2μm，有(you)光斑，聲音(yin)異常，或滾(gun)(gun)(gun)刀(dao)(dao)(dao)齒(chi)(chi)背(bei)磨(mo)(mo)(mo)損大(da)于(yu)0.2ー0.5mm，粗(cu)齒(chi)(chi)大(da)于(yu)0.8ー1.0mm時(shi)，應重磨(mo)(mo)(mo)滾(gun)(gun)(gun)刀(dao)(dao)(dao)。注意滾(gun)(gun)(gun)刀(dao)(dao)(dao)的(de)(de)(de)(de)再(zai)磨(mo)(mo)(mo)，使(shi)刀(dao)(dao)(dao)片(pian)保持在(zai)基本蝸桿的(de)(de)(de)(de)螺旋表面(mian)(mian)。如(ru)果滾(gun)(gun)(gun)刀(dao)(dao)(dao)的(de)(de)(de)(de)再(zai)磨(mo)(mo)(mo)不正確，滾(gun)(gun)(gun)刀(dao)(dao)(dao)的(de)(de)(de)(de)原始精度就會喪失。滾(gun)(gun)(gun)刀(dao)(dao)(dao)的(de)(de)(de)(de)刀(dao)(dao)(dao)片(pian)磨(mo)(mo)(mo)削應在(zai)專(zhuan)(zhuan)用(yong)輥(gun)磨(mo)(mo)(mo)機上進行。如(ru)果沒(mei)有(you)專(zhuan)(zhuan)用(yong)工具(ju)磨(mo)(mo)(mo)床，可以(yi)在(zai)工具(ju)磨(mo)(mo)(mo)床上安(an)裝(zhuang)專(zhuan)(zhuan)用(yong)夾具(ju)重新(xin)研磨(mo)(mo)(mo)滾(gun)(gun)(gun)刀(dao)(dao)(dao)。專(zhuan)(zhuan)用(yong)夾具(ju)使(shi)滾(gun)(gun)(gun)刀(dao)(dao)(dao)螺旋運動，分度精確。小心不要徒手磨(mo)(mo)(mo)。

齒(chi)(chi)(chi)(chi)向(xiang)(xiang)誤(wu)差(cha)(cha)(cha)(cha)(cha)：齒(chi)(chi)(chi)(chi)向(xiang)(xiang)誤(wu)差(cha)(cha)(cha)(cha)(cha)主要分布在(zai)分度(du)(du)(du)圓柱(zhu)體上，在(zai)全(quan)齒(chi)(chi)(chi)(chi)寬范圍(wei)內，兩個(ge)齒(chi)(chi)(chi)(chi)向(xiang)(xiang)線之間(jian)(jian)的(de)(de)(de)端面(mian)距離。齒(chi)(chi)(chi)(chi)向(xiang)(xiang)誤(wu)差(cha)(cha)(cha)(cha)(cha)的(de)(de)(de)原因是刀架(jia)(jia)和機(ji)床(chuang)的(de)(de)(de)垂直進給(gei)方向(xiang)(xiang)與(yu)零件軸(zhou)線偏移；滾(gun)(gun)齒(chi)(chi)(chi)(chi)機(ji)尾座頂中(zhong)心(xin)與(yu)工作臺(tai)旋轉中(zhong)心(xin)之間(jian)(jian)存在(zai)偏差(cha)(cha)(cha)(cha)(cha)；計算差(cha)(cha)(cha)(cha)(cha)動(dong)掛輪(lun)時，誤(wu)差(cha)(cha)(cha)(cha)(cha)過(guo)大(da)，導(dao)致(zhi)傳動(dong)鏈齒(chi)(chi)(chi)(chi)輪(lun)調整制造誤(wu)差(cha)(cha)(cha)(cha)(cha)較大(da)。此外，由于(yu)精度(du)(du)(du)低(di)，齒(chi)(chi)(chi)(chi)坯和滾(gun)(gun)齒(chi)(chi)(chi)(chi)夾具(ju)的(de)(de)(de)制造和安裝也(ye)會導(dao)致(zhi)齒(chi)(chi)(chi)(chi)向(xiang)(xiang)誤(wu)差(cha)(cha)(cha)(cha)(cha)。齒(chi)(chi)(chi)(chi)坯、機(ji)床(chuang)、夾具(ju)等誤(wu)差(cha)(cha)(cha)(cha)(cha)也(ye)會導(dao)致(zhi)齒(chi)(chi)(chi)(chi)向(xiang)(xiang)誤(wu)差(cha)(cha)(cha)(cha)(cha)。齒(chi)(chi)(chi)(chi)面(mian)粗糙(cao)度(du)(du)(du)：一般(ban)來說，齒(chi)(chi)(chi)(chi)面(mian)粗糙(cao)度(du)(du)(du)差(cha)(cha)(cha)(cha)(cha)主要表現為啃牙(ya)、發紋、撕裂、魚鱗(lin)等。機(ji)床(chuang)刀架(jia)(jia)滑(hua)板也(ye)會影響到滾(gun)(gun)齒(chi)(chi)(chi)(chi)的(de)(de)(de)齒(chi)(chi)(chi)(chi)向(xiang)(xiang)誤(wu)差(cha)(cha)(cha)(cha)(cha)，比如，刀架(jia)(jia)滑(hua)板和回轉軸(zhou)線之間(jian)(jian)的(de)(de)(de)平行度(du)(du)(du)。因此，提升刀架(jia)(jia)導(dao)軌精度(du)(du)(du)也(ye)是提升滾(gun)(gun)齒(chi)(chi)(chi)(chi)精度(du)(du)(du)的(de)(de)(de)一種方法。
