圓柱齒(chi)(chi)(chi)(chi)輪(lun)是(shi)(shi)機(ji)械齒(chi)(chi)(chi)(chi)輪(lun)中最(zui)重要(yao)(yao)的(de)(de)齒(chi)(chi)(chi)(chi)輪(lun)類(lei)型之一，也是(shi)(shi)最(zui)常見的(de)(de)齒(chi)(chi)(chi)(chi)輪(lun)類(lei)型。圓柱齒(chi)(chi)(chi)(chi)輪(lun)根據輪(lun)齒(chi)(chi)(chi)(chi)的(de)(de)方向可分(fen)為(wei)直圓柱齒(chi)(chi)(chi)(chi)輪(lun)、斜圓柱齒(chi)(chi)(chi)(chi)輪(lun)和(he)(he)人字圓柱齒(chi)(chi)(chi)(chi)輪(lun)，用于在(zai)兩個軸之間傳(chuan)遞運(yun)(yun)動(dong)(dong)和(he)(he)動(dong)(dong)力，是(shi)(shi)應用最(zui)廣泛(fan)的(de)(de)傳(chuan)動(dong)(dong)機(ji)構。它通過(guo)輪(lun)齒(chi)(chi)(chi)(chi)的(de)(de)嚙合實現傳(chuan)動(dong)(dong)要(yao)(yao)求，與(yu)摩擦輪(lun)、皮帶輪(lun)等機(ji)械傳(chuan)動(dong)(dong)相比，具有傳(chuan)動(dong)(dong)比穩定、運(yun)(yun)行可靠、效率高、使用壽命(ming)長、直徑合適等特(te)點。
