圓(yuan)(yuan)柱(zhu)齒(chi)(chi)輪是(shi)機械齒(chi)(chi)輪中最(zui)(zui)重要的齒(chi)(chi)輪類(lei)型(xing)之一，也是(shi)最(zui)(zui)常見的齒(chi)(chi)輪類(lei)型(xing)。圓(yuan)(yuan)柱(zhu)齒(chi)(chi)輪根(gen)據輪齒(chi)(chi)的方向(xiang)可(ke)分為(wei)直圓(yuan)(yuan)柱(zhu)齒(chi)(chi)輪、斜圓(yuan)(yuan)柱(zhu)齒(chi)(chi)輪和(he)人(ren)字圓(yuan)(yuan)柱(zhu)齒(chi)(chi)輪，用(yong)于在兩個(ge)軸之間傳遞運(yun)動(dong)(dong)和(he)動(dong)(dong)力，是(shi)應(ying)用(yong)最(zui)(zui)廣泛的傳動(dong)(dong)機構。它(ta)通(tong)過輪齒(chi)(chi)的嚙合(he)實現傳動(dong)(dong)要求，與摩擦輪、皮帶輪等機械傳動(dong)(dong)相比(bi)，具有傳動(dong)(dong)比(bi)穩定、運(yun)行(xing)可(ke)靠、效率高、使用(yong)壽(shou)命長、直徑(jing)合(he)適等特點。
