SLOTTED BEARING WITH LABYRINTH SEAL RINGS FOR DAMPER ACTUATORS

摘要

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.
