    摘要： A rotary indexing mechanism comprising a support and a turntable mounted on the support for rotation about its axis. A first crown gear is fixedly mounted on the support coaxial with the axis of the turntable and a second crown gear concentric with the first crown gear is connected with the turntable for rotation therewith. Opposite the first and the second crown gears are two concentric crown gears which are connected by flexible means for simultaneous rotation about the aforementioned axis and slithgly shiftable relative to each other in axial direction. The opposite gears can be moved in axial direction relative to the first and the second gear to bring the teeth out of engagement, permitting turning of the turntable, or to engage the teeth for locking the turntable in its turned position.

    摘要： A rotary indexing machine in which for alternately turning the turntable one step in its peripheral direction and locking it between the steps the turntable is only rotatably mounted and immovable in its axial direction . This is effected by means of three crown gears, the first of which is secured to the turntable and surrounds a second stationary crown gear of the same pitch, while a third crown gear is alternately movable in opposite axial directions for simultaneously engaging it with the first and second gears so as to lock them to each other and thus to lock the turntable during its stopping periods and for disengaging it from the first and second gears during the turning movements of the turntable.
