  • Patent number: 9714584
    Abstract: A damping treatment is applied to the ligaments of a squirrel cage type bearing support. The damping treatment reduces the vibrations transmitted to the engine casing as the engine passes through various resonance frequencies of the various parts of the gas turbine engine. A squeeze-film damper damps engine vibrations, but the oil in the squeeze-film damper can act as a stiffener during certain operational ranges, which increases the transmission of vibrations to the engine structure. Applying a damping treatment to the ligaments of the squirrel cage provides effective vibration damping.

In a wave spring, a high mountain portion and a low mountain portion form a combination, and the combination is repeatedly formed along a circumferential direction. A valley portion is formed between the mountain portions. Since distance between mountain portions is constant in the conventional design of wave springs, the ratios of spring constant are only specific values (plot indicated by ?). In contrast, in the design of the wave spring, since the pitch angle A of the high mountain portion and the pitch angle B of the low mountain portion can be changed in the combination, the ratio can be freely adjusted.

  • Patent number: 8950739
    Abstract: The first corner portion elastically deforms in application of load such that the angle of the first corner portion changes depending on the pressing force from the first member. In this case, the first corner portion can move toward the outside of the inner periphery portion of the main body portion while the angle changes. The second corner portion has the same function as that of the first corner portion, and it can move toward the outside of the outer periphery portion of the main body portion while the angle changes depending on the pressing force from the second member in the elastic deformation of the second corner portion. As a result, the spring can prevent generation of hysteresis in load characteristics without increasing the number of parts, and enables height adjustment of the spring.

The cup-shaped washer selectively engages an axially fixed adjacent structure, such as a thrust washer, during disengagement of the disconnect shaft and attendant spring compression. The present disconnect shaft arrangement obviates the need for a retaining ring against which the spring compresses, such that the relatively deep retaining ring groove needed for such a retaining ring need not be cut into the outer surface of the disconnect shaft. Removal of material in the outer surface of the shaft is therefore minimized, such that the torque transmission capability of the shaft is maximized.

  • Patent number: 8602656
    Abstract: An alternator has front and rear bearings, supported by front and rear frames, to rotatably support a shaft of a rotor extending along axial direction. A washer is located between the rear frame and the rear bearing to apply pressing force to the rear bearing slightly movable along axial direction. The washer has a ring-shaped base portion concentrically located with the rear bearing, slanting portions extending from the base portion toward outside of radial direction such that two adjacent slanting portions arranged as each pair along circumferential direction are inclined to different sides of axial direction, and flattened portions extending from respective slanting portions toward outside and being parallel to the base portion. Flattened portions shifted to front side are in contact with the rear bearing, and flattened portions shifted to rear side are in contact with the rear frame.
