摘要： A clutch arrangement is provided with a clutch housing that connects a drive unit to an output, such as a transmission, which is rotatable around a central axis and with which an axial central projection is associated at the side of the clutch housing facing the drive unit in the radial extension area of its rotational center. The axial central projection receives a rotor carrier receiving a rotor of an electric machine. The central projection is connected at least so as to be fixed with respect to relative rotation to the drive unit via a first connection device and to the rotor carrier via a second connection device.

摘要： A gas turbine engine according to an example of the present disclosure includes, among other things, a propulsor section including a propulsor supported on a propulsor shaft, a turbine section including a turbine shaft, and an epicyclic gear train interconnecting the propulsor shaft and the turbine shaft. The epicyclic gear train includes a sun gear coupled to the turbine shaft, intermediary gears arranged circumferentially about and meshing with the sun gear, a carrier supporting the intermediary gears, and a ring gear including first and second portions each having an inner periphery with teeth intermeshing with the intermediate gears. The first and second portions have axially opposed faces abutting one another at a radial interface and respective flanges extending along the radial interface radially outward from the teeth. The first and second portions define a trough axially between and separating the teeth of the first portion from the teeth of the second portion. The first and second portions include facing recesses that form an internal annular cavity along the radial interface.

摘要： A shaft and hub connection assembly including a shaft and a hub each extending along and rotatable about an axis. One of the shaft and the hub defines a male connection portion, and the other of the shaft and the hub defines a female connection portion. The female connection portion has a radially inner surface comprised of a plurality of inside faces. The male connection portion has a radially outer surface comprised of a plurality of outside faces that nest within the inside faces. A plurality of outside transition regions are located between the outside faces in a circumferential direction and are blended at an outside radius. A plurality of inside transition regions are located between the inside faces of the female connection portion in the circumferential direction and are blended at an inside radius. A gap is provided between the outside and inside transition regions.

摘要： A method of manufacturing a rotating bearing unit includes to cause one end surface in the axial direction of the forming punch (46), formed by combining a plurality of punch elements (46, 46) divided in the circumferential direction, which are displaceable in the axial direction and which are not displaceable in the circumferential direction, and having a processing teeth (44, 44) at one end surface in the axial direction, to face the other end surface of the caulking section (20) in the axial direction. In this state, rolls (30a) are rotated about the central axis (α) of the hub main body (8) while pressing the other end surface of the forming punch (46) in the axial direction with a pressing surface (43) of the roll (30a) having a central axis (β) that is inclined with respect to the central axis (α) of the hub main body (8).

摘要： An epicyclic gear train for a gas turbine engine according to an example of the present disclosure includes, among other things, a gutter having an annular channel, a sun gear rotatable about an axis, intermediary gears arranged circumferentially about and meshing with the sun gear, a carrier supporting the intermediary gears, and a ring gear arranged about and intermeshing with the intermediary gears, the ring gear having an aperture axially aligned with the annular channel. The ring gear includes axially spaced apart walls that extend radially outward to define a passageway, and the passageway is arranged radially between the aperture and the annular channel such that the walls inhibit an axial flow of an oil passing from the aperture toward the annular channel.

摘要： The disclosure relates to a main shaft of a wind turbine with mounting segments. The main shaft includes a shaft portion and a disc portion. The disc portion includes a coupling surface, a hollow portion, and an alignment portion. The alignment portion is characterized by one or more mounting segments coupled with the alignment portion. The mounting segments are configured to align a component of the wind turbine with the central axis of the main shaft. Further, the one or more mounting segments are coupled to the alignment portion using at least one fastening device. The mounting segments have a thickness ‘t’ that may be constant or varied based on the component 32 of the wind turbine coupled to the main shaft.
