Inventors:

Mark Leonard Hopper - West Chester OH, US
Joshua Dean Smith - Cincinnati OH, US

International Classification:

F16F 9/14
F16F 15/16

US Classification:

188297

Abstract:

An annular dashpot damper is utilized to provide flow resistance from viscous shear to an orifice or gap which provides flow metering. This is accomplished by dividing the flow channel into circumferential segments or damping cavities which are sealed and limit rotational flow of the fluid.

Abstract:

A housing for retention of the outer race of a bearing of a gas turbine engine includes an arrangement of spring fingers that yields a lightweight housing capable of withstanding very high radial loads combined with very high torsional windup and axial thrust load. Controlled circumferential gaps on both sides of each spring finger limit the deflection and self-arrest the distortion of the housing. The spring fingers define at least one side edge that extends at an angle relative to the axial direction. An axial gap is created on the aft end by a portion of the spring finger beam structure that opposes an axial face of the housing and limits the axial distortion. A radial gap created between interface hardware of the housing and the inner retention housing also acts to retain the spring finger housing under load in a radial direction.
