    摘要: In a turret indexing device, a coupling containing three gear members is employed in a turret indexing device to cooperate with an indexing disc mounted on an output shaft which is adapted to hold an indexing head. The coupling is operated by a first cam fixedly mounted on an input shaft through a lever mechanism, and the indexing disc is driven by a second cam fixedly mounted on the same input shaft. The three gear members include a first gear member fixedly mounted on a collar slidably mounted on the output shaft, a second gear member which is fixedly mounted on a stationary housing, and third gear member fixedly mounted on a head end of the output shaft. The collar with the first gear member is operated by the lever mechanism to cause the first gear to engage with and disengage from the second gear member and the third gear member while the first cam rotates, in a present timing sequence, and the indexing disc is caused to rotate only when the first gear member is disengaged from the second gear member and the third gear member.
