齒(chi)(chi)(chi)(chi)(chi)(chi)條(tiao)(tiao)(tiao)(tiao)是(shi)一種(zhong)齒(chi)(chi)(chi)(chi)(chi)(chi)分布于(yu)條(tiao)(tiao)(tiao)(tiao)形體上的(de)特殊(shu)齒(chi)(chi)(chi)(chi)(chi)(chi)輪。齒(chi)(chi)(chi)(chi)(chi)(chi)條(tiao)(tiao)(tiao)(tiao)也分直(zhi)(zhi)齒(chi)(chi)(chi)(chi)(chi)(chi)齒(chi)(chi)(chi)(chi)(chi)(chi)條(tiao)(tiao)(tiao)(tiao)和斜(xie)齒(chi)(chi)(chi)(chi)(chi)(chi)齒(chi)(chi)(chi)(chi)(chi)(chi)條(tiao)(tiao)(tiao)(tiao)，分別與直(zhi)(zhi)齒(chi)(chi)(chi)(chi)(chi)(chi)圓(yuan)柱齒(chi)(chi)(chi)(chi)(chi)(chi)輪和斜(xie)齒(chi)(chi)(chi)(chi)(chi)(chi)圓(yuan)柱齒(chi)(chi)(chi)(chi)(chi)(chi)輪配對(dui)使用；齒(chi)(chi)(chi)(chi)(chi)(chi)條(tiao)(tiao)(tiao)(tiao)的(de)齒(chi)(chi)(chi)(chi)(chi)(chi)廓為(wei)直(zhi)(zhi)線而(er)非漸開(kai)線（對(dui)齒(chi)(chi)(chi)(chi)(chi)(chi)面而(er)言(yan)則為(wei)平面），相當于(yu)分度(du)圓(yuan)半徑為(wei)無窮(qiong)大(da)圓(yuan)柱齒(chi)(chi)(chi)(chi)(chi)(chi)輪。

商品說明

精密齒輪(lun)齒條加工定制

齒(chi)(chi)(chi)條是一種齒(chi)(chi)(chi)分布(bu)于條形體上的(de)特殊齒(chi)(chi)(chi)輪(lun)。齒(chi)(chi)(chi)條也分直齒(chi)(chi)(chi)齒(chi)(chi)(chi)條和斜(xie)齒(chi)(chi)(chi)齒(chi)(chi)(chi)條，分別與直齒(chi)(chi)(chi)圓柱(zhu)齒(chi)(chi)(chi)輪(lun)和斜(xie)齒(chi)(chi)(chi)圓柱(zhu)齒(chi)(chi)(chi)輪(lun)配對使(shi)用；齒(chi)(chi)(chi)條的(de)齒(chi)(chi)(chi)廓為(wei)直線(xian)而非漸(jian)開(kai)線(xian)（對齒(chi)(chi)(chi)面(mian)而言則(ze)為(wei)平面(mian)），相當于分度圓半(ban)徑為(wei)無(wu)窮大圓柱(zhu)齒(chi)(chi)(chi)輪(lun)。

齒(chi)(chi)條是與齒(chi)(chi)輪(lun)相配的(de)一(yi)(yi)種條形零(ling)件。它等于直徑無限大(da)的(de)一(yi)(yi)個齒(chi)(chi)輪(lun)周緣的(de)一(yi)(yi)段(duan)。一(yi)(yi)邊(bian)均勻分布著許多齒(chi)(chi)，與齒(chi)(chi)輪(lun)相嚙合，將(jiang)轉動(dong)變(bian)為移動(dong)，或將(jiang)移動(dong)變(bian)為轉動(dong)。

（1）由于齒(chi)條(tiao)齒(chi)廓為(wei)直線，所(suo)以齒(chi)廓上各點具有相同的壓力角，且(qie)等于齒(chi)廓的傾斜角，此角稱為(wei)齒(chi)形(xing)角，標準值為(wei)20°，目前定位齒(chi)條(tiao)多(duo)為(wei)斜齒(chi)，齒(chi)形(xing)角19°31′42″。

（2）與齒(chi)頂線平(ping)行的任一條直線上(shang)具有相(xiang)同的齒(chi)距(ju)和(he)模數。

（3）與齒頂(ding)線(xian)平行(xing)且齒厚等于齒槽寬的直線(xian)稱為分(fen)度(du)線(xian)（中(zhong)線(xian)），它是計(ji)算齒條尺(chi)寸的基準線(xian)。

目(mu)前自(zi)動化設備主要(yao)以斜齒條為主，具有精度高、扭矩大等特(te)點。
