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.

Transmission/gearbox vibration damping system

Vibration and shock isolation, as well as working fluid flow path sealing in a turbine-type power plant having a turbine housing 18 with a radially directed peripheral outlet 38 is achieved by locating the turbine housing 18 within a tubular housing 44 with a radially inwardly opening port 46 aligned with the turbine housing outlet 38 and disposing elastomeric seal and turbine mounts 50, 52 mounted on spaced side walls 28 and 30 for sealing the outlet 38 to the port 46 and to serve as engine mounts for a turbine wheel 10 and the turbine housing 18.

Seal and turbine mount

The outlet 38 of a turbine housing 18 may be sealed to a port 46 while at the same time mounting a turbine 10 and associated transmission 36 for vibration and shock isolation by locating elastomeric seal and turbine mounts 50, 52 on opposed walls 28 and 30 of the turbine housing 18 defining the outlet 38.
