An anisotropic member can include an annular body configured to receive a semi-floating bearing and to space the bearing a distance from a bore surface and can be configured to impart anisotropic stiffness and damping terms to the semi-floating bearing when positioned in the bore. Such a member is suitable for use in a rotating assembly for a turbocharger where the bearing may be a semi-floating bearing. Various exemplary members, bearings, housings, assemblies, etc., are disclosed.

摘要： An apparatus and method that provides a flexible anisotropic support, which may accommodate open, closed, or re-circulating squeeze film damper in parallel, has improved internal rolling element clearances, limits maneuver and blade loss responses by limiting rotor excursion, and has a rotor centering feature. This is accomplished through the combination of beam and ring arrangement, which provides support anisotropy that produces beneficial cross-coupling stiffness for the support to control synchronous and non-synchronous vibration.

摘要： A synchronous signal generator is provided for use in conjunction with an aircraft engine having a spool and an engine output shaft driven by the spool. The synchronous signal generator includes a generator housing, a generator output member rotatably mounted in the generator housing, a once-per-revolution timing mark on the generator output member, and conversion gearing disposed within the housing and configured to couple the engine output shaft to the generator output member. The conversion gearing rotates the generator output member at substantially the same rotational frequency as the spool when the conversion gearing is coupled to the engine output shaft.

摘要： An apparatus includes a rotor group rotatable within the apparatus and a bearing assembly supporting the rotor group. A support structure supports the bearing assembly and is fixed in the apparatus. The support structure includes a support housing, an anisotropic support that engages the bearing assembly and the support housing, and a squeeze film cavity that is defined between the anisotropic support and the support housing. A damper fluid supply line is in fluid communication with the squeeze film cavity. A fluid interruption device is disposed in the damper fluid supply line. A method of damping the apparatus includes supplying fluid under pressure to the squeeze film cavity through the damper fluid supply line. Upon surpassing a predetermined value of a variable correlated to rotational speed of the rotor group, the fluid flow to the squeeze film cavity is interrupted with the fluid interruption device.
