精密齒輪齒條加(jia)工定制

齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)條(tiao)是(shi)一種(zhong)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)分(fen)布于條(tiao)形體上的特殊齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)輪。齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)條(tiao)也分(fen)直(zhi)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)條(tiao)和斜齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)條(tiao)，分(fen)別與直(zhi)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)圓(yuan)(yuan)柱齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)輪和斜齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)圓(yuan)(yuan)柱齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)輪配對使用； 齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)條(tiao)的齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)廓(kuo)為直(zhi)線(xian)而非(fei)漸開線(xian)（對齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)面而言則為平面），相當于分(fen)度圓(yuan)(yuan)半徑為無(wu)窮大(da)圓(yuan)(yuan)柱齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)輪。

齒條是與齒輪相配的(de)一(yi)種條形(xing)零件。它等于直徑無限大的(de)一(yi)個齒輪周緣的(de)一(yi)段。一(yi)邊均勻分布著許多齒，與齒輪相嚙合，將轉(zhuan)動(dong)(dong)(dong)變(bian)為(wei)(wei)移動(dong)(dong)(dong)，或將移動(dong)(dong)(dong)變(bian)為(wei)(wei)轉(zhuan)動(dong)(dong)(dong)。

（1） 由于(yu)齒(chi)(chi)條(tiao)(tiao)齒(chi)(chi)廓為(wei)(wei)(wei)直線，所以齒(chi)(chi)廓上各點具有相同的壓力角(jiao)，且等于(yu)齒(chi)(chi)廓的傾斜角(jiao)，此角(jiao)稱(cheng)為(wei)(wei)(wei)齒(chi)(chi)形(xing)角(jiao)，標準(zhun)值為(wei)(wei)(wei)20°，目前定位齒(chi)(chi)條(tiao)(tiao)多為(wei)(wei)(wei)斜齒(chi)(chi)，齒(chi)(chi)形(xing)角(jiao)19°31′42″。

（2） 與齒頂線平(ping)行的(de)任(ren)一(yi)條(tiao)直(zhi)線上(shang)具有相同的(de)齒距和模(mo)數。

（3） 與齒頂線(xian)(xian)平(ping)行且齒厚等于(yu)齒槽寬(kuan)的(de)直線(xian)(xian)稱為(wei)分度線(xian)(xian)（中線(xian)(xian)），它是計算齒條尺(chi)寸的(de)基(ji)準線(xian)(xian)。

目前自動化設備主要(yao)以斜齒條為主，具有精度高、扭矩(ju)大等特點。
