Abstract: Various embodiments of the teachings herein include an axle receiving arrangement with components that can move in opposite directions and in each case move in the direction of an axle that is received by the arrangement. These components can be part of a tensioning side or a compressing side of the arrangement. The arrangement has at least two components that can be combined with one another and one of said components is in contact with the axle surface participates in a positive-locking and non-positive locking fixing of the axle by the axle receiving arrangement and the other of said components ensures the movability in the direction of the axle. The components in the combined state enclose a gap between on the one hand convex and on the other hand concave curved surfaces.

Abstract: Various embodiments of the teachings herein include an axle receiving arrangement for fixing to an axle comprising multiple components movable in opposite directions with respect to an axle received by the axle receiving arrangement. The multiple components are parts of a tensioning side or compressing side of the axle receiving arrangement. There is a tension bracket movable on the tensioning side, the tension bracket including a thread in engagement with a thread of a nut. The thread of the tension bracket on a tension bracket upper part, starting on an underside of the tension bracket upper part and terminating below an upper side of the tension bracket upper part. A circumferential annular gap on the upper side of the tension bracket upper part is defined by the termination of the thread below the upper side.

Abstract: An actuating drive contains a housing which has a first housing part and a second housing part. The two housing parts each have an edge, each edge having an end face, and the two end faces face each other when the two housing parts are joined. The first housing part and the second housing part can be detachably joined. The actuating drive is configured to accommodate an exchangeable connection module for a cable feed. The exchangeable connection module can be inserted into an opening of the first edge of the first housing part and the exchangeable connection module can be connected in a form-closed manner to the end faces of the edges in a region of the opening when the two housing parts are joined. Thus, an actuating drive, in particular for ventilation flaps or fire dampers, having high flexibility in the electrical connection contacting is provided.

Abstract: A drive for adjusting the damper of a building air vent has a main body formed with a receiving aperture. A bearing ring is arranged in the receiving aperture and secured to the main body. The bearing ring has a circumferential direction, wherein the bearing ring has a first end and a second end in circumferential direction. The first end and the second end can be spaced apart in the circumferential direction such that there is a gap between the first end and the second end. A hub for actuating the drive shaft of the damper is fixed to the bearing ring such that the hub is rotatably mounted on the main body relative to the bearing ring.

Abstract: An actuating drive (1) has a housing (4) which also affords protection from splashed water and which comprises two housing portions (5; 6), wherein the two housing portions (5; 6) each have an edge (20; 40) with a respective end face (21; 41) which are disposed in opposite relationship when the housing portions are assembled. When the two housing portions (5; 6) are assembled zones which act in different ways are formed between the two end faces (21; 41). A first zone (Z1) in which the two housing portions (5; 6) are in contact with each other is provided on the housing (4) towards the exterior. A second zone (Z2) having a passage (55) is provided beside the first zone (Z1), towards the interior. The passage (55) of the second zone (Z2) is closed towards an internal space (33) of the housing by a third zone (Z3) in which the two housing portions (5; 6) are not in contact with each other.

Abstract: A drive device for controlling the position of an actuator includes an electric motor for actuating the drive device. The motor is coupled to a gear mechanism and adapted to control the position of the actuator by selective operation thereof. A gear mechanism operatively coupled to the motor and to the actuator has a restoring spring and an auxiliary spring, each of which is tightenable to store energy therein by operation of the motor upon startup. In the event of a power loss to the motor, the gear mechanism operates to use the stored energy of the restoring spring to move the actuator to a preselected position. The stored energy of the auxiliary spring is used to counteract against moment of the motor at rest.
