ABSTRACT:
The axis of a gear is to follow a trajectory having a salient point. To this end, the gear rolls along two stationary toothed racks. A change-over toothing is provided between these two toothed racks. This change-over toothing extends non-smoothly with respect to the toothed racks. Such change-over toothing permits the gear to roll, without jamming, from one of the toothed racks to the other one, with its axis following a trajectory having a salient point.
