摘要： A centering ring may be used to provide a resilient mounting system with uniform stiffness for rotating machinery. The centering ring may have first and second exterior raised ridges on one surface and a central raised ridge on the other surface. The centering ring may be disposed between the housing of the rotating machinery and a bearing provided therein. Due to its uniform cross-sectional geometry about its entire circumference, the centering ring may provide uniform stiffness in any radial direction. The centering ring may be useful in any rotating machinery, including generators, turbo machines and turbine engines.

摘要： Centering rings may be used to modify the combined resonance of a rotor and its support assembly to migrate the rotor critical speeds such that they can be engineered out of the rotor operating speed range. The centering rings of the present invention may be useful for any rotating electrical machinery, especially high speed aerospace applications, such as generators and starter-generators.

摘要： A rotor mount assembly for an electrical machine, such as a high speed aerospace generator, comprises a spring having a simple annular structure together with an oil squeeze film damper (SFD). The spring is engineered to move the rotor critical speeds outside of the extremes of the operating speed range and the SFD damps out the rotor responses as the speed passes through these points.

摘要： A disengagement/disconnect assembly for disengaging a generator from a gear box may include an inner ball screw having an angled threading on an outer surface thereof and surrounding and operatively engaged to a rotating generator drive shaft to cause rotation of the inner ball screw. The inner ball screw may be attached to an engagement member having undercut and interlockable teeth engaged to corresponding teeth of an engagement member of the gear box. An outer ball screw may surround and normally rotate with the inner ball screw. A helical ball track may be formed between the inner and outer ball screws. A brake may be provided for slowing or stopping rotation of the outer ball screw so that the inner ball screw rotates relative to the outer ball screw along the ball track and slides axially away from the gear box thereby disengaging the generator from the gear box drive shaft.

摘要： A permanent magnet rotor of a generator is used to excite a permanent magnet stator to generate electric power for the generator and to control a disengagement mechanism whereby the generator can disengage from an accessory, such as a gear box drive shaft, when the generator is not working properly. The permanent magnet is affixed to an outer ball screw which normally rotates with an inner ball screw that is operatively engaged to the accessory. An increased load to the permanent magnet stator slows or stops rotation of the permanent magnet rotor and outer ball screw, causing the inner ball screw to move axially from the outer ball screw and away from an accessory and toward a re-settable lock.

摘要： A high speed, high power generator has its main stator and main rotor configured to provide enhanced cooling capability. The generator includes a generator housing, a stator, a shaft, and a rotor. The stator is mounted within the generator housing. The shaft is rotationally mounted within the generator housing, and includes an inner surface that defines an internal fluid flow passage, an outer surface, and a plurality of interlamination cooling supply orifices extending between the shaft inner and outer surfaces. The rotor is mounted on the shaft and includes a plurality of poles formed from laminations, and one or more interlamination disks. Each interlamination disk is disposed between at least two of the laminations and includes a plurality of interlamination flow passages that receive a cooling medium from the shaft and direct the cooling medium, via centrifugal force, through the rotor and onto the stator.

摘要： A high speed generator cooling system directs a cooling oil spray through a chamber inside a coil support wedge assembly, which may be disposed adjacent to the generator coils. Heat from the generator coils may be conducted through the walls of the coil support wedge assembly and into the chamber where it is removed by the cooling oil spray passing through the chamber. The cooling oil passes through a generator rotor shaft and into a cooling passage in least one of the rotor laminations.
