Abstract
A flexible coupling for flexibly connecting two rotary drive shafts includes a first coupling flange connected to the first shaft, a second coupling flange connected to the second shaft, a flexible disk arranged between the two coupling flanges, and four connector bolts that respectively connect the two flanges to the flexible disk. A first pair of the bolts is securely connected to the first flange and to the flexible disk, while passing with free play through a clearance hole in the second flange. A second pair of the bolts is securely connected to the second flange and to the flexible disk, while passing with free play through a clearance hole in the first flange. In ordinary operation, the connection and force transmission between the coupling flanges is carried out through the flexible disk. If the flexible disk or one or more of the connector bolts fails, then the connection and force transmission between the two coupling flanges will be carried out directly through the connector bolts in a fail-safe operating mode. The flexible coupling is especially adapted for use in a transmission system for transmitting drive power from a central drive unit to the high lift flaps and slats of an aircraft.
