ABSTRACT:
A spring drive mechanism for power switch gear. The mechanism includes an engagement shaft free to rotate about its own axis and carrying both a large toothed wheel and a cam. An engagement spring constituted by a traction spring is coupled to the large toothed wheel at an attachment point by a chain. The large toothed wheel meshes with a small toothed wheel which is coupled via a gear train to a driving gearwheel secured to an outlet shaft of a drive motor. In the predetermined direction A of rotation, the large toothed wheel includes a discontinuity in its teeth, thereby generating a gap which constitutes a zone without teeth, and in which a retractable tooth is disposed. Following the retractable tooth, the large toothed wheel has an additional discontinuity in its teeth over at least two meshing steps. This mechanism is advantageous as switchgear for a circuit breaker.
