Noise damping coupling between barrel motor and winding shaft for shutters

摘要

The coupling (10) contains a central hole (14) for receiving a drive shaft, preferably belonging to the barrel motor (12). The outer profile (16) of the coupling is adapted to the cross-sectional shape of the winding shaft. The central hole is present in an inner section (18) of the coupling, this section being received by a passage in the outer section (24) of the coupling that forms its outer profile. An Independent claim is also included for the process used to make the coupling, by injecting a two-component mixture into the gap between the two coupling sections in order to fill it with an elastomer.
