Abstract
A vibration damping system for a transmission or gearbox which includes rotatable components. A housing structure is provided for supporting and journalling an inner rotatable component drivingly coupled to a plurality of outer rotatable components defining a plural load path. A compliant bearing is disposed between the housing and the inner rotatable component. The compliant bearing includes a laminated structure having an inner bearing member journalled on the housing, an outer bearing member supporting and journalling the inner rotatable component, and a resilient damping layer sandwiched between the inner and outer bearing members. A liquid squeeze film is located between the outer bearing member and the inner rotatable component, and passages through the housing and the compliant bearing supply liquid for the squeeze film.
