優質齒條

齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)條(tiao)(tiao)可看作一(yi)個(ge)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)數為(wei)(wei)無窮多(duo)的(de)(de)(de)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)輪的(de)(de)(de)一(yi)部(bu)分(fen)(fen)(fen)，這時齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)輪的(de)(de)(de)各圓均變(bian)為(wei)(wei)直(zhi)(zhi)線，作為(wei)(wei)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)廓(kuo)的(de)(de)(de)漸(jian)開線也(ye)變(bian)為(wei)(wei)直(zhi)(zhi)線 齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)條(tiao)(tiao)與齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)輪相(xiang)比，其(qi)(qi)特點(dian)為(wei)(wei)： 由(you)于(yu)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)條(tiao)(tiao)的(de)(de)(de)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)廓(kuo)是直(zhi)(zhi)線，所(suo)(suo)以齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)廓(kuo)上(shang)(shang)(shang)各點(dian)的(de)(de)(de)法線平行(xing)(xing)，而且在傳動(dong)時齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)條(tiao)(tiao)是做平動(dong)，齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)廓(kuo)上(shang)(shang)(shang)各點(dian)速度的(de)(de)(de)大(da)小和方向一(yi)致所(suo)(suo)以各點(dian)的(de)(de)(de)壓力角相(xiang)等，其(qi)(qi)大(da)小等于(yu)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)廓(kuo)的(de)(de)(de)傾(qing)斜角，稱(cheng)為(wei)(wei)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)形(xing)角 由(you)于(yu)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)條(tiao)(tiao)上(shang)(shang)(shang)各齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)同側(ce)的(de)(de)(de)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)廓(kuo)是平行(xing)(xing)的(de)(de)(de)，所(suo)(suo)以不論在分(fen)(fen)(fen)度線上(shang)(shang)(shang)或齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)頂線上(shang)(shang)(shang)或與其(qi)(qi)平行(xing)(xing)的(de)(de)(de)其(qi)(qi)它直(zhi)(zhi)線上(shang)(shang)(shang)，其(qi)(qi)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)距都相(xiang)等齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)條(tiao)(tiao)也(ye)分(fen)(fen)(fen)直(zhi)(zhi)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)條(tiao)(tiao)和斜齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)條(tiao)(tiao)，分(fen)(fen)(fen)別(bie)與直(zhi)(zhi)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)圓柱(zhu)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)輪和斜齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)圓柱(zhu)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)輪配對使用； 　

齒(chi)條的齒(chi)廓為(wei)直線(xian)而非漸(jian)開線(xian)（對(dui)齒(chi)面(mian)而言(yan)則為(wei)平(ping)面(mian)），相當于分度圓半徑為(wei)無窮大圓柱(zhu)齒(chi)輪　　

齒條的主要特點

（1） 由于(yu)齒條(tiao)齒廓為直線，所以齒廓上各(ge)點具有相同的壓力角，且等于(yu)齒廓的傾斜角，此角稱為齒形角，標準值(zhi)為20°。　　

（2） 與齒頂線(xian)平行的任(ren)一條直線(xian)上具(ju)有相(xiang)同(tong)的齒距和模數。　　

（3） 與齒頂線平行(xing)且(qie)齒厚等于(yu)齒槽寬的(de)直線稱為分度線（中(zhong)線），它是計算齒條尺寸的(de)基準線。
