一般鼓形齒聯軸器的齒頂高指數為l，外齒全高h=2．25m，內、外齒分度圓齒薄厚基本相同。它的關鍵優勢是內、外齒生產加工工藝性能好，能用標準齒輪端銑刀或插齒刀開展生產加工。可是，這類鼓形齒聯軸器的(de)外(wai)(wai)(wai)傳(chuan)動齒(chi)(chi)輪(lun)(lun)輪(lun)(lun)齒(chi)(chi)彎(wan)曲(qu)(qu)強度(du)(du)比內(nei)傳(chuan)動齒(chi)(chi)輪(lun)(lun)輪(lun)(lun)齒(chi)(chi)彎(wan)曲(qu)(qu)強度(du)(du)要低，因(yin)而(er)，外(wai)(wai)(wai)齒(chi)(chi)通(tong)常在于齒(chi)(chi)型(xing)損(sun)壞而(er)無效。為提(ti)升(sheng)鼓形(xing)齒(chi)(chi)聯(lian)(lian)軸(zhou)(zhou)器(qi)承(cheng)載力和使用(yong)(yong)(yong)期(qi)，有學(xue)者根據之內(nei)、外(wai)(wai)(wai)齒(chi)(chi)輪(lun)(lun)齒(chi)(chi)彎(wan)曲(qu)(qu)強度(du)(du)同樣為總體目標(biao)的(de)提(ti)升(sheng)測(ce)算，得(de)到(dao)齒(chi)(chi)頂高指數為0．7的(de)結(jie)果，即選用(yong)(yong)(yong)短厚齒(chi)(chi)齒(chi)(chi)型(xing)。當鼓形(xing)齒(chi)(chi)聯(lian)(lian)軸(zhou)(zhou)器(qi)選用(yong)(yong)(yong)這類獨(du)特(te)的(de)短厚齒(chi)(chi)型(xing)時，因(yin)為適度(du)(du)提(ti)升(sheng)了外(wai)(wai)(wai)傳(chuan)動齒(chi)(chi)輪(lun)(lun)齒(chi)(chi)厚，其中、外(wai)(wai)(wai)傳(chuan)動齒(chi)(chi)輪(lun)(lun)傳(chuan)動齒(chi)(chi)輪(lun)(lun)彎(wan)曲(qu)(qu)強度(du)(du)貼近(jin)，因(yin)而(er)，承(cheng)載力提(ti)升(sheng)，使用(yong)(yong)(yong)期(qi)增(zeng)加(jia)。在處理好機械加(jia)工(gong)加(jia)工(gong)工(gong)藝的(de)前提(ti)條(tiao)件下，設(she)計制作聯(lian)(lian)軸(zhou)(zhou)器(qi)商品中應用(yong)(yong)(yong)優化的(de)齒(chi)(chi)頂高指數，針(zhen)對提(ti)升(sheng)聯(lian)(lian)軸(zhou)(zhou)器(qi)的(de)承(cheng)載力，增(zeng)加(jia)使用(yong)(yong)(yong)期(qi)無外(wai)(wai)(wai)乎一個方法。
