Abstract

A link-type coupling particularly suited for use in connecting a drive shaft to a rotor hub in an aircraft for permitting the hub to rotate about an axis that may be angularly misaligned with respect to the rotational axis of the drive shaft. The coupling includes a series of links arranged tangentially with respect to the hub and shaft and connected thereto by laminated elastomeric bearings at the ends of the links. The laminated elastomeric bearings accommodate the motion of each link while transferring torque between the shaft and hub.
