    摘要： When the output shaft (14) of a high speed motor is supported pivotally by accommodating front and rear bearings (18) and (34) on the center side of housings (30, 34) at the front and rear end portions of a motor housing, respectively, the present invention provides a bearing structure of a high speed motor using oil-air lubrication by constituting the inner peripheral portion (16, 32) of each of the front and rear housings in such a manner as to be capable of being separated from or assembled to respective outer peripheral portion and to facilitate machining, and a supply path (20, 40) of oil-air and a drain path (22, 42) are disposed on each inner peripheral portion.

    摘要： A heat sink (32) and bearing support (30) arrangement for an armature shaft (22) of an electric motor in an electrically actuated device comprises a thin walled body fabricated by sheet metal processes. The support body (32) has a generally mushroom shaped configuration which includes integrally formed central shoulder and collar segments. A bearing body (30) is supported by the central segment and the collar segment engages a housing part (34) for supporting the assembly in the device.

    摘要： A rotating electric machine (60) comprising a rotor (62,286), a rotating shaft (70) and a bearing (400) supporting the shaft in a housing (22,27). The shaft (66,70) comprises a plurality of shaft portions (70a-70e), their outer diameters become larger in a stepwise manner from the first portion (70a) until a fourth portion (70d). The second shaft portion (70b) is smaller in diameter than a third shaft portion (70c). A plurality of groove shaped flow paths (230) are formed in said second shaft portion (70b) by being recessed inwardly in radial direction and extend in axial direction and form a portion of the rotor internal flow path (250). An inner circumferential surface of said bearing (400) covers said groove shaped flow paths (230) and whereby enabling a liquid coolant (CO) to flow through a rotor internal flow path (250) on an inner side of said rotor in axial direction.
