精密齒輪齒條加工定(ding)制

齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)條(tiao)(tiao)(tiao)是(shi)一種齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)分(fen)布于條(tiao)(tiao)(tiao)形體上的特殊(shu)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)。齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)條(tiao)(tiao)(tiao)也分(fen)直(zhi)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)條(tiao)(tiao)(tiao)和斜(xie)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)條(tiao)(tiao)(tiao)，分(fen)別(bie)與直(zhi)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)圓(yuan)柱(zhu)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)和斜(xie)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)圓(yuan)柱(zhu)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)配對使用； 齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)條(tiao)(tiao)(tiao)的齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)廓為(wei)直(zhi)線而非漸開線（對齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)面而言(yan)則為(wei)平面），相當于分(fen)度圓(yuan)半徑為(wei)無(wu)窮大圓(yuan)柱(zhu)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)。

齒(chi)條是與齒(chi)輪相配的一種(zhong)條形零件。它等于直徑無限大(da)的一個齒(chi)輪周緣的一段。一邊(bian)均勻分布著許多齒(chi)，與齒(chi)輪相嚙合(he)，將轉(zhuan)動(dong)變為移動(dong)，或將移動(dong)變為轉(zhuan)動(dong)。

（1） 由于(yu)齒(chi)條齒(chi)廓為(wei)(wei)直(zhi)線，所以(yi)齒(chi)廓上各(ge)點具有相同的(de)壓力角(jiao)(jiao)(jiao)，且等(deng)于(yu)齒(chi)廓的(de)傾斜(xie)角(jiao)(jiao)(jiao)，此(ci)角(jiao)(jiao)(jiao)稱為(wei)(wei)齒(chi)形角(jiao)(jiao)(jiao)，標準(zhun)值為(wei)(wei)20°，目前定位(wei)齒(chi)條多(duo)為(wei)(wei)斜(xie)齒(chi)，齒(chi)形角(jiao)(jiao)(jiao)19°31′42″。

（2） 與齒(chi)頂線平行的任(ren)一條(tiao)直線上具有(you)相同(tong)的齒(chi)距和模(mo)數。

（3） 與齒(chi)頂線平行且齒(chi)厚等于齒(chi)槽(cao)寬的直(zhi)線稱為分度(du)線（中(zhong)線），它是計算(suan)齒(chi)條尺寸的基準線。

目前自動化設備主(zhu)要(yao)以斜(xie)齒條為主(zhu)，具(ju)有(you)精度(du)高(gao)、扭矩大等特點。
