ABSTRACT:
A flexible coupling for drivingly connecting driving and driven members and for accommodating both angular and endwise misalignment of such members comprises a plurality of quadrilateral flex frames arranged face-to-face along the central axis of the coupling. The two end frames are connected respectively to the driving and driven members through opposite corner portions of each such frame. Among the flex frames themselves, each frame is connected to the next adjacent frame by having two of its opposite corner portions rigidly connected to two opposite corner portions of the adjacent frame. The joint between each pair of connected corner portions is of an improved construction which maximizes the flexing length of the flex frame legs and otherwise provides benefits resulting in the coupling having improved performance and reliability, particularly with regard to applications requiring the transmission of high levels of torque at high rotational speeds and with possibly high amounts of angular and endwise misalignment.
