ABSTRACT:
In order to lock a drive system from operation during maintenance procedures, while providing a positive mechanical engagement regardless of index position, a locking mechanism includes a sector gear associated with a rotatably mounted shaft. The rotatably mounted shaft and the sector gear have a common axis of rotation which extends generally tangentially of a system gear associated with a mechanical transmission of the drive system. With the system gear being mounted for rotation in a plane and having a plurality of equally spaced teeth completely about the periphery thereof, the sector gear also includes a plurality of equally spaced teeth, but disposed about only a portion of the periphery thereof. The rotatably mounted shaft is disposed in spaced relation to the teeth of the system gear and the sector gear is mounted for rotation into and out of the plane of the system gear. Moreover, the locking mechanism includes a lost motion mechanism accommodating limited relative rotation between the rotatably mounted shaft and the sector gear and also includes a cam accommodating limited axial movement of the sector gear relative to the rotatably mounted shaft, whereby the teeth of the sector gear are automatically aligned during rotation for meshing enagagement with the teeth of the system gear.
