A turbine balance assembly has a turbine rotor and shaft. Bearings are positioned radially outwardly of the shaft. A bearing sleeve is positioned radially outwardly of the bearings, and supports the bearings. The bearing sleeve extends along an axial length defined by a rotational axis of the shaft, and has a turbine rotor end adjacent to the turbine rotor, and a remote end. A radially outwardly extending flange on the bearing sleeve extends radially outwardly of a support portion of the bearing sleeve at the turbine rotor end. The flange has a nominal outer diameter, and includes a slot for receiving an anti-rotation tab from a gear cage over a first circumferential extent. A bearing sleeve incorporates the anti-rotation feature, and a gear cage incorporates its portion of the anti-rotation feature. An air turbine starter, and a method of installing components of a turbine balance assembly are also disclosed.

A bushing for use in a planetary gear system has a cylindrical body portion defining a bore extending along a central axis to be received on a planetary gear shaft. A tab extends axially beyond a nominal body portion of the bushing and is received in a notch in a thrust washer adjacent to the bushing to prevent rotation of the thrust washer. A gear cage and an air turbine starter incorporating the bushing, along with a method of installing the bushing are also disclosed.

A lubrication management system for a rotating shaft assembly includes a shaft rotatable about a central axis and in operable connection with at least one component, wherein lubrication is supplied proximate an outer diameter of the shaft. Also included is a lubrication manipulation device for directing the lubrication radially away from the outer diameter of the shaft, wherein the lubrication manipulation device comprises a threaded portion for fixedly securing the lubrication manipulation device to the outer diameter of the shaft.

A rotary rectifier assembly including a shaft adapted to be rotated. Three equally angularly spaced phase conductors are disposed about the shaft and insulated with respect to each other and with respect to the shaft and each has opposed, axially opening recesses. Diode wafers are received in each of the recesses and each recess further receives an electrically conductive load shoe. A pair of end conductors sandwich the phase conductors, wafers and load shoes and each end conductor has three equally angularly spaced curved recesses for matingly receiving the curved portion of the corresponding ones of the load shoes. A single biasing device is employed to bias one end conductor towards the other to thereby establish good electrical contact between the various components while occupying a minimum of space and minimizing the overall weight of the assembly.

Difficulties in interrupting a mechanical power transmission path may be minimized in a manual connect-disconnect operator which includes a coupling shaft (38) and a translatable carrier (28) journalling the coupling shaft (38) for rotation about an axis and mounting the coupling shaft (38) for axial movement along the axis between connect and disconnect positions. A yoke (52) is mounted on a pivot (54) and is connected to the carrier (28) for translating the carrier (28) to move the coupling shaft (38) upon pivotal movement of the yoke (52). A manual actuator (78) is mounted for reciprocating movement and a detent mechanism (92), (94), (100), (102), (104), (106), (108) is operable to maintain the carrier (28) in either of the positions.

A rotatable rectifier assembly for use in a brushless generator. A housing 40 receives a stack of heat sinks 56-68 which are both thermally and electrically conductive and which sandwich diode wafers 78 making up a multiple phase, full wave rectifier. The requisite electrical connections are made by electrical connectors 102,110 slidably extending through the heat sinks and electrically connected to desired ones of the heat sinks and electrically isolated from other ones of the heat sinks.

Turbine nozzle phasing device for controlling a flow of gasses to a plurality of nozzles in response to a control signal. The turbine nozzle phasing device includes a housing having a lower portion which includes a first plenum for receiving the flow of hot gasses and an upper portion which includes a second plenum integral with the first plenum, a detachable partition for separating the first plenum from the second plenum and a first nozzle which communicates with the first plenum. Hot gasses flowing into the first plenum flows through the first nozzle. A set of second nozzles is provided which communicates with the second plenum. Partition detaching apparatus is also included for detaching the detachable partition in response to the control signal to permit a portion of the hot gasses flowing into the first plenum to flow into the second plenum and through the set of second nozzles.
