    摘要： A turbo machine according to the present disclosure includes a rotating shaft, an impeller, a first bearing, and a first supply passage. The rotating shaft includes a first taper portion and a first cylindrical portion. The first bearing includes a first taper support surface and a first cylindrical portion support surface, the first taper support surface including a first taper hole forming surface and rotatably supporting the first taper portion, the first cylindrical portion support surface rotatably supporting the first cylindrical portion. The first supply passage is open to a space formed between the first cylindrical portion and first cylindrical portion support surface. An inclination angle of the first taper hole forming surface with respect to the axial direction of the first bearing is greater than an inclination angle of an outer surface of the first taper portion with respect to the axial direction of the rotating shaft.

    摘要： Improved electric motor for a fluid circulator comprising a permanent magnet rotor (2), a stator (3), in which a supporting and containing hollow body (4) for the rotor (2) is housed, an impeller (5), a shaft (6) of the electric motor kinematically coupled to the rotor (2) and to the impeller (5) for activating the impeller (5) in rotation. Advantageously, the rotor (2) comprises an axial thrust bearing member (7; 10), made of anti-friction material and adapted for supporting axil loads produced during the fluid circulation in the circulator, said thrust bearing member being integrated inside the rotor itself, so that the thrust bearing member does not separate from the rotor during a motor disassembly.

    摘要： A housing (40) is formed with an impeller side communicating passage (51) extending from an impeller chamber (45) in a direction including a component of an outer side (Dro) in a radial direction, circulating channels (52) extending from the impeller side communicating passage (51) in a direction including a component of a front side (Daf) in the axial direction, and a suction side communicating passage (55) communicating with the circulating channel (52) and a suction channel (41) that guides a gas into the impeller chamber (45). A radial dimension (Ri) from an axis (Ar) to a communicating position at which each of the circulating channels (52) communicates with the suction side communicating path (55) is larger than a radial dimension (Ro) from the axis (Ar) to a communication position with the impeller side communicating path (51) in the circulating channel (52). A channel area (Ao) of the circulating passage (52) at a communicating position for the suction side communicating passage (55) is larger than a channel area (Ai) of the circulating channel (52) at a communicating position for the impeller side communicating passage (51).

    摘要： A gas turbine engine (100) has an engine static structure (130). At least one component rotatable relative to the engine static structure (130) about an engine axis of rotation (A). A fan (42) is coupled to at least one component for rotation about the engine axis of rotation (A). An actuator (132) is mounted to the engine static structure (130), wherein the actuator (132) is activated to prevent the fan (42) from rotation and is inactivated to allow the fan (42) to rotate. A method for preventing rotation of a fan (42) in a gas turbine engine (100) is also disclosed.

    摘要： A shaft (21) has an axis (X-X), an outer surface (60), an inner surface (62) and is arranged to rotate in a first circumferential direction (R). The shaft (21) comprises a first set of equally circumferentially spaced apertures (56) extending through the shaft (21) between the outer and inner surfaces (60, 62) of the shaft (21). A second set of equally circumferentially spaced apertures (58) extends through the shaft (21) between the outer and inner surfaces (60, 62) of the shaft (21). The first and second sets of apertures (56, 58) are arranged in first and second planes (P1, P2) arranged perpendicularly to the axis (X-X) of the shaft (21). The second plane (P2) is spaced axially downstream from the first plane (P1). Each aperture in the second set of apertures (58) is circumferentially displaced in a second circumferential direction from a circumferential mid position between the two apertures in the first set of apertures (56) to reduce the stresses in the shaft (21).
