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.
Claims8
A toothing assembly comprising toothing means having two toothed rack means and a gear defining an axis and arranged to roll along said stationary toothing means and to pass, during its rolling motion, from one of said toothed rack means to the other one, wherein a change-over toothing means is provided between said toothed rack means, said change-over toothing means extending non-smoothly with respect to said toothed rack means to generate a trajectory of the axis of said rolling gear relative to said toothing means, said trajectory having a discontinuity of its tangent in a salient point.
