The invention provides a multi-ball pin coupling and a steering mechanism. A main body (M) of the multi-ball pin coupling comprises a first connecting piece (M1) and a second connecting piece (M2), the first connecting piece (M1) comprises a multi-ball pin assembly (30) and a raceway assembly (40), the second connecting piece (M2) comprises a sleeve (60), the raceway assembly (40) comprises an inner raceway retainer (41) and N pairs of inner raceways (42), the raceway assembly (40) is arranged in the sleeve (60) in a sleeved mode, the inner raceway retainer (41) and the sleeve (60) cannot rotate relative to each other, the multi-ball-pin assembly (30) comprises a pin shaft (31) and N ball rings (33) surrounding the pin shaft (31), N is not smaller than 3, and each ball ring (33) is clamped on the two sides in the circumferential direction by a pair of inner raceways (42). According to the multi-ball pin coupling, vibration in the transmission process can be reduced, and torque can be effectively transmitted under the condition that axial deviation exists between transmission parts. According to the steering mechanism, reversing gaps and vibration impact are not prone to being generated.
本发明提供一种多球销式联轴器和转向机构,多球销式联轴器的主体(M)包括第一联接件(M1)和第二联接件(M2),第一联接件(M1)包括多球销组件(30)和滚道组件(40),第二联接件(M2)包括套管(60),滚道组件(40)包括内滚道保持架(41)和N对内滚道(42),滚道组件(40)套设在套管(60)内,内滚道保持架(41)与套管(60)不能相对转动,多球销组件(30)包括销轴(31)和围绕销轴(31)的N个球环(33),N不小于3,每个球环(33)被一对内滚道(42)在周向两侧夹紧。根据本发明的多球销式联轴器能降低传动过程的振动并能在传动部件之间具有轴向偏移的情况下有效传递扭矩。根据本发明的转向机构不容易产生换向间隙和振动冲击。
