Abstract (en)
A building chain actuator drive arrangement (1) comprising a worm screw (2) having a center axis (C) and a motor (5) configured to rotate the worm screw (2) around the center axis (C). A bearing (6) having a center axis coaxial with the center axis (C) is provided to support the worm screw (2). A bracket element (7) and/or a housing element, is connected to the motor (5) and comprises an axially extending recess (8) configured to accommodate the bearing (6). A resilient assembly (12) is arranged adjacent the recess (8) and configured to allow the bearing (6) to be inserted into the recess (8) by moving the bearing (6) in a first direction (D1) along the center axis (C), and to prevent the bearing (6) from moving in a second, opposite direction (D2) after the bearing (6) has been fully inserted into the recess (8).
