Abstract (en)

A building chain actuator drive arrangement (1) comprising a worm screw (2) having a center axis (C) and a worm wheel (3) configured to engage the worm screw (2). A motor (5) is operatively connected to the worm screw (2) and configured to rotate the worm screw (2) around the center axis (C). An at least partially tubular bracket element (7) is configured to at least partially accommodate the worm screw (2) and is connected to the motor (5), as well as fixed to a center shaft (3a) of the worm wheel (3). At least one radial damping element (18) is configured to reduce transmission of vibrations from the motor (5) to the remainder of the building chain actuator drive arrangement (1), the radial damping element(s) (18) having center axes coaxial with the center axis (C) and the radial damping element(s) (18) being arranged concentrically with at least one of the bracket element (7) and the motor (5).
