The window shutter driving assembly has an axle with mounted regulating rollers, on one side, joined with a coupling to an axially-positioned worm of a worm gear, mounted in the housing, on the other side of the assembly. Unique characteristics: The coupling has the form of a two-stage cylinder. It consists of a cylindrical bolt (4) fitted into the worm (2) opening. The bolt has a paraboloidal tip (12) with a transversal slit (8) and a lateral longitudinal bevel (13), which corresponds to the width of the worm (2) and forms a nib (11). The coupling also consists of a socket (5) joined to the square tip of the axle (6). The socket has a lateral recess (10) with edges equipped with protrusions (9). The edges of the protrusions are drawn aside. |
