Device for driving section of sun protection or roller shutter, has thermal coupling of outer-side main shaft and room-side drive shaft, where room side drive shaft has coupling element made of plastic

摘要

The device has a thermal coupling of an outer-side main shaft (2) and a room-side drive shaft (1). The room side drive shaft has a coupling element made of plastic. The drive shaft and main shaft in the coupling element (3) have rounded or profiled cross-section, and are enclosed by a sprayed core-like coupling element. A transmission of torque of the drive shaft and the main shaft are provided in the coupling element. The drive shaft is thermally separated with the main shaft by a space.
