ABSTRACT:
An improved coupling device for joining two rotatable members which may undergo misalignment is disclosed. The device includes a plurality of balls for operatively coupling the two rotatable members. One disclosed embodiment of the coupling device is a plunging joint and another disclosed embodiment of the coupling device is a fixed joint. The joints can be used independently or, alternatively both types of joints can be combined in tandem to provide an improved transmission drive. Each joint is connected between a driving member and a driven member. The coupling device comprises laminated bearing units of alternating layers of resilient and nonextensible materials. The units are designed to carry in compression torque loads transmitted through the device. The units of the plunging joint accommodate in shear (1) relative axial misalignment or plunging motion and/or (2) relatively small angular motion between the driving and driven members to which the joint is connected, while the units of the fixed joint accommodate in shear relative angular misalignment or pivotal motion between the driving and driven members to which the joint is connected from the respective rotation axes of the driving and driven members.
