摘要

The coupling is for the rotary connection between a drive-and a take-off member, e.g. travelling gear, or switch gear; to connect adjusting elements to the drive member. A helical spring (1) is connected to the drive-and take-off member, and has two sections, wound in opposite directions, one of which may be actively connected to the drive-(6) or take-off (2) member. The free end of the connected spring section (1b) is connected non-turnable to the other member (2, 6). The second spring section (1a) is connected to a third stationary member (3). for an adjustment of drive and take-off relative to each other, there is an additional spring to release the helical spring. One end of the additional spring is anchored to the drive member, or a section fastened to it. The other spring end engages on the take-off member, so that this may be turned relative to the drive member in a direction, corresponding to the drive direction.
