    摘要: A turbomachine includes: a rotational shaft; a pair of thrust collars disposed around the rotational shaft; a thrust bearing disposed around the rotational shaft at an axial directional position between the pair of thrust collars; and an oil-drain channel disposed around the rotational shaft, for draining lubricant oil after lubricating a sliding portion between the thrust bearing and the thrust collars. The oil-drain channel includes: an oil-drain port portion for discharging the lubricant oil inside the oil-drain channel downward; and an oil-guide channel portion disposed above the oil-drain port portion and configured to guide the lubricant oil from the sliding portion in a circumferential direction of the rotational shaft to the oil-drain port portion. The oil-guide channel portion has an asymmetric shape with respect to a rotational direction of the rotational shaft, the oil-guide channel portion having a minimum flow-path cross sectional area at a first position on an upstream side in the rotational direction, and a maximum flow-path cross sectional area at a second position on a downstream side of the first position.

    摘要: An aerofoil array for a gas turbine system has an inner annular platform and an outer annular platform, which extend about a longitudinal axis and radially delimit an annular channel for a gas flow; the annular channel houses a plurality of aerofoils, arranged at a substantially constant angular pitch and comprising respective central portions and respective ends connected to the platforms; the aerofoils are formed by two series of aerofoils having a different geometrical feature in order to intentionally vary the eigenfrequencies and arranged about the longitudinal axis with a sequence that is regularly repeated all along the annular channel; even though the external geometry of the aerofoils is varied, the cross-sections remain unchanged in the central portions, at any given radius with respect to the longitudinal axis.

    摘要: A bushing includes a body extending from a first end to a second end through an intermediate portion. The body includes a passage having a first centerline extending from the first end to the second end. A first alignment member is formed on a first section of the intermediate portion at the first end. The first alignment member includes an outer surface having a plurality of splines configured to be received by a first component to be joined. A second alignment member is formed on a second section of the intermediate portion. The second alignment member includes a second centerline that is off-set relative to the first centerline and is configured to be received by a second component to be joined with the first component.

    摘要: A bearing assembly includes a sleeve and a bearing located within a bore of the sleeve. The sleeve extends between an inner surface and an outer surface. The inner surface at least partially defines the bore, which extends through the sleeve. The inner surface is configured eccentric to the outer surface. The bearing includes a plurality of rolling elements arranged between an inner ring and an outer ring. The outer ring is mounted to the sleeve.
