摘要： A turbine starter (10) is provided including a housing (21) defining a fluid passageway (22) with an inlet (24) and an outlet (26). A turbine rotor (16) is supported in the housing (21) and includes blades (18) arranged in the passageway (22) between the inlet (24) and the outlet (26). The rotor (16) is movable within the passageway (22) at a speed with a fluid exiting the blade (18) toward the outlet (26). The spoiler (34) is arranged in the passageway (22) between the rotor (16) and the outlet (26). The spoiler (34) deflects the fluid exiting the blade (18) and reduces the rotor speed. Preferably, the present invention spoiler (34) is utilized to reduce the maximum speed at the no-load condition. The angle, number, position, and other characteristics of the spoiler (34) may be tailored for the particular turbine and a particular speed for which it is desirable to reduce.

摘要： A bearing is provided particularly suitable for a turbine and turbine related components used in the aerospace industry. More particularly, the bearing is suitable for such applications as pneumatic starters for turbines. The bearing is preferably constructed from a M50 steel, which typically has a pre-treated hardness in the range of approximately 60 to 64 Rc. With the present invention, the bearing is nitrided to obtain a case hardness of approximately 74 Rc. To achieve such a case hardness, the bearing may require nitriding over several days. In one preferred embodiment of the present invention, a pneumatic starter includes a shaft, preferably constructed from M50, that has a portion of its outer surface nitrided. The nitrided surface functions as an inner race of a bearing assembly. Nitriding the portion of the shaft extends the bearing life of the bearing due to its increased harness.

摘要： A diffuser includes multiple vanes rotatable about pivot pins between multiple positions. A mounting plate supports a backing plate. The vanes are arranged between the backing plate and the shroud. The pivot pins are in a slip fit relationship with the backing plate, vanes and shroud and are threadingly received by bosses in the mounting plate. The mounting plate and pivot pin arrangement better enables the backing plate and shroud to remain parallel with one another during deflection of the backing plate and/or shroud. Structure, such as integral protrusions and/or bolts, extend from between the backing plate and shroud through apertures in the vanes to better contain the vanes in the event of a catastrophic failure.

摘要： A motor is provided including a housing having separate motor and bearing cooling inlets. The motor is arranged within the housing and includes a stator and a rotor assembly supported on air bearings. The motor cooling inlet is in fluid communication with the stator, and the bearing cooling inlet is in fluid communication with the air bearings. The motor cooling inlet provides a first cooling fluid at a first pressure on the rotor assembly, and the bearing cooling inlet provides a second cooling fluid at a second pressure on the rotor assembly that is different than the first pressure. The pressures exerted on the rotor assembly produce bearing loads that generally cancel one another. This may be achieved by providing a vent in the housing that is common to both the motor cooling inlet and the bearing cooling inlet. As a result, journal bearings and seals of substantially the same size may be used, and several seals may be eliminated.
摘要翻译：提供一种电动机，其包括具有分离的电动机和轴承冷却入口的壳体。电动机布置在壳体内，并且包括定子和支撑在空气轴承上的转子组件。电机冷却入口与定子流体连通，轴承冷却入口与空气轴承流体连通。电动机冷却入口在转子组件上以第一压力提供第一冷却流体，并且轴承冷却入口在与第一压力不同的转子组件上的第二压力下提供第二冷却流体。施加在转子组件上的压力产生通常相互抵消的轴承负载。这可以通过在壳体中提供与电动机冷却入口和轴承冷却入口共同的通气来实现。因此，可以使用基本上相同尺寸的轴颈轴承和密封件，并且可以消除几个密封件。
