摘要:
A turbine engine provides a differential gear system coupling the turbine to the bypass fan and the compressor. In this manner, the power/speed split between the bypass fan and the compressor can be optimized under all conditions. In the example shown, the turbine drives a sun gear, which drives a planet carrier and a ring gear in a differential manner. One of the planet carrier and the ring gear is coupled to the bypass fan, while the other is coupled to the compressor.

A gas turbine engine accessory (20') is removably mounted to a gearbox (30') of a gas turbine engine (10). The accessory has a drive shaft (35) extending into the gearbox (30'). A driven gear (36a') is mounted on the drive shaft (35). The driven gear (36a') is adapted to directly engage a drive gear (40') of the gearbox (30'). The purpose of this improved design is to lighten the overall weight of the gas turbine engine by reducing its number of parts and components.
摘要:
An epicyclic gear carrier assembly for use in an epicyclic gear train of a gas turbine engine, the epicyclic gear train (12) having a central axis and a plurality of epicyclic gears (18) rotatable about individual gear axes (34). The epicyclic gear carrier assembly (24) comprises at least a carrier plate (26) defining a plurality of circumferentially spaced axle bores (32) which are disposed radially outward from the central axis and are co-axial with the individual gear axes (34). A plurality of corresponding gear axles (34) are disposed within the axle bores (32), and the plurality of epicyclic gears (18) are rotatably mounted to the gear axles (34) via bearing elements (36). An epicyclic carrier member (40) comprises a plurality of axle engaging elements (54) that are co-axial with the gear axles (34) and are engaged thereto by load transmission members such that load is transferred from the gear axles (34) to the epicyclic carrier member (40).

The invention relates to a gas turbine arrangement (1) comprising a gas turbine (2), a generator (3) and a gearbox (4). The gearbox (4) is connected to an output shaft (5) from the gas turbine and an input shaft (6) to the generator. The gas turbine arrangement (1) also comprises a starter motor (7) which is connected to an output shaft (8) from the generator (3).
摘要:
Gas turbine (1), in particular for model aircraft, model helicopters and other small propulsion units, comprising a drive shaft (3), extending through an annular combustion chamber (2), rotatably mounted by means of two main bearings (13,13') and connected to a compressor rotor (4) and a turbine rotor (11) and a driven shaft (14) driven by the drive shaft (3). A device with a curvic gears is provided for torque transfer from the drive shaft (3) to the driven shaft (14), between the two main bearings (13, 13').
摘要:
The invention concerns an arrangement for retaining a stub shaft (113) bearing (14) comprising a stop (117), a nut (121) and a braking part (124) preventing the nut (121) from rotating involuntarily. When the shaft (33) located in the cavity (12) is dismantled by being pulled towards the right, the braking part (124) can be reached, (124), removed, then the screw (121) loosened and be removed in turn: the stub shaft (113) is released and can be detached without having to dismount another stub shaft (34) located opposite the stub shaft (113) and the retaining arrangement. The stub shaft (113) can belong to a high pressure compressor of an aircraft engine gas turbine.
摘要:
A coupling arrangement for coupling a driving unit (1) to a driven unit (2) includes a combination of a shear coupling (7) which acts between the units and which fails immediately an overload occurs, and a brake coupling (13) which is adapted to become active between the units (1, 2) when the shear coupling (7) fails.
摘要:
A spray bar 120, for lubricating gear meshes in an epicyclic transmission 1, has a base 130 having an inlet 123 designed to receive, in use, a flow of pressurized oil; the spray bar 120 has two tube portions 140a, 140b, which project from the base 130 along respective axes, define respective channels 138a, 138b parallel to each other and permanently communicating with the inlet 123, and are laterally defined by respective outer surfaces 142a, 142b having outlet nozzles for spraying oil from the channels 138a,138b.
摘要:
The invention relates to a guard device (8) comprising an enclosure (10) for enclosing a first machine (4), a coupling guard (12) for covering a coupling device (20) that is prepared for connecting the first machine (4) to a second machine (6), the enclosure (10) being connected to the coupling guard (12). In order to achieve improved operational characteristics of the guard device (8) it is proposed that the guard device (8) comprises an elastic component (32) that elastically connects the enclosure (10) to the coupling guard (12).
