摘要： A drive mechanism for an electric propulsion system (4) that comprises an electric machine (18) is disclosed. The drive mechanism (16) comprises a drive shaft (10) with a longitudinal axis A, an engagement means, and a disconnect mechanism (52). The engagement means comprises a drive shaft engagement element (56) and an electric machine engagement element (58). The drive engagement element (56) comprises a first and second shaft gear ring, and each shaft gear ring is supported on the drive shaft. Each shaft gear ring comprises a plurality of gear teeth (36) which are circumferentially disposed around the drive shaft, and the gear teeth extend radially outward from the drive shaft. The gear teeth of the first shaft gear ring have an axial length L1, and the first and second shaft gear rings are axially spaced from each other along the drive shaft by a distance L2. The electric machine engagement element comprises a first and second gear set. The first and second gear sets each comprise a plurality of gear teeth (30) which are configured to mesh with the gear teeth of the first and second shaft gear rings respectively; the gear teeth of the first gear set have an axial length L3. The first and second gear sets are separated from each other by a length L4 in the axial direction. Length L1 is less than length L4, and length L3 is less than length L2. The disconnect mechanism is configured to reversibly move one of at least part of the drive shaft engagement element and at least part of the electric machine engagement element relative to the other of the engagement elements in an axial direction between a first position and a second position. In the first position the gear teeth of the first shaft gear ring are meshed with the gear teeth of the first gear set and the gear teeth of the second shaft gear ring are meshed with the gear teeth of the second gear set, and in the second position the gear teeth of the first shaft gear ring are axially between the first and second gear sets and the gear teeth of the first shaft gear ring are not meshed with the gear teeth of the first or second gear sets.

摘要： The tubular shaft splicing device comprises adjacent first and second end portions (11, 21) of two tubular shaft stretches (10, 20), one or more splicing plates (30, 40) superimposed to opposite sides of the first and second end portions (11, 21) of the tubular shaft stretches, and passing-through locking members (51, 52) inserted in aligned locking holes (13, 14; 23, 24; 33, 34; 43, 44) formed in the first and second end portions (11, 21) of the tubular shaft stretches (10, 20) and in the one or more splicing plates (30, 40). The passing-through locking members have a rectangular or trapezium cross-section and the locking holes formed in the first and second end portions of the tubular shaft stretches and in the one or more splicing plates have a conjugated rectangular or trapezium shape, with two sides of the rectangular or trapezium shape being parallel to a longitudinal axis of the tubular shaft.

摘要： An assembly for a coupling together rotatable components according to an example of the present disclosure includes, among other things, a rotor shaft (142) extending along a centerline axis, the rotor shaft defining an inner bore (170) extending from an axial end of the rotor shaft, a gear (140) mounted on an outer diameter of the rotor shaft, a lock nut (164) threadedly engaged with the outer diameter of the rotor shaft such that the lock nut abuts against an axial end face of the gear, and a retainer (168) including a step portion extending from a head portion and including a projection portion (168C) extending from the step portion. The projection portion is insertable into the inner bore to bias the lock nut against the axial end face of the gear, and the step portion is dimensioned to establish an interference fit with the rotor shaft along the inner bore. A starter assembly and a method of assembly are also disclosed.

摘要： A quick-release connector (10) for connecting a first part constituted by an angling device (80) to a second part constituted by a bank stick or a buzz bar (82) or other angling device. It comprises an insert (14) having a circular cross-section and is secured to one of such first and second parts (80) when the connector (10) is in use. A pod (12) having a recess of circular cross-section to receive the insert (14) is secured to the other of such first and second parts (82) when the connector (10) is in use. The connector (10) further comprises at least one displaceable locking member (44) retained within the pod (12).The pod (12) is displaceable between an engagement position in which it engages the insert (14) when the connector (10) is in use to lock the insert (14) and the pod (12) and hence such first and second parts (80, 82) together when the connector (10) is in use, and a non-engagement position in which it does not so engage the insert (14). A locking component (28) is retained on the pod (12) and is moveable between a first position in which it holds the said at least one displaceable locking member (44) in the said engagement position and a second position in which the said at least one displaceable locking member (44) is released from the said engagement position. The movement of the locking component (28) between its said first and second positions is a rotary movement.

摘要： Example torque tube assemblies for use with aircraft high lift devices are described herein. An example torque tube assembly (200) includes a torque tube (304) having a first end (302) and a second end (308) opposite the first end. A first fitting is coupled to the first end and a second fitting is coupled to the second end. The first fitting is to be coupled to a first high lift device of an aircraft. The second fitting (800) has a spline section (910). The torque tube assembly also includes a sliding spline shaft (804) having a channel (902) and a first yoke (810). The second fitting (800) is slidably received within the channel (902). The torque tube assembly further includes a spline coupling (808) having a second yoke (812), which is coupled to the first yoke (810) of the sliding spline shaft (804) to form a U-joint (806). The spline coupling (808) is to be coupled to a second high lift device of the aircraft.
