齒chi式shi聯lian軸zhou器qi是shi由you齒chi數shu相xiang同tong的de內nei齒chi圈quan和he帶dai外wai齒chi的de凸tu緣yuan半ban聯lian軸zhou器qi等deng零ling件jian組zu成cheng。外wai齒chi分fen為wei直zhi齒chi和he鼓gu形xing齒chi兩liang種zhong齒chi形xing，所suo謂wei鼓gu形xing齒chi即ji為wei將jiang外wai齒chi製zhi成cheng球qiu麵mian，球qiu麵mian**在齒輪軸線上

，齒側間隙較一般齒**，鼓形齒聯軸器可允許較大的角位移（相對於直齒聯軸器），可改善齒的接觸條件，提高傳遞轉矩的能力，延長使用壽命。有角位移時沿齒寬的接觸狀態。
