EINORGANANTRIEB FÜR EINE VERTIKALJALOUSIE

摘要

The drive member is rotatably coupled to an epicyclic gear train sun wheel (3) and by torque transmitting coupling to the splined shaft. The coupling blocks in both directions after a preset number of revolutions. The gear train outer ring (4) has torque transmitting link to the drive wheel for the full string. The coupling between the centre wheel (3) of the planet gear and the splined shaft (10) is formed by a toothed collar (8) on the wheel and a toothed section (9) on outside of the shaft.
