Device 100 as described in this article is provided and means that the failure of such as one of main drive shaft 30A, 30B person allows horse Up to 16 two radome fairing actuating systems 62A, 62B of control, although bigger than the difficulty during normal operating.

Fig. 2 schematically shows the decomposition views of the device 100 of operation as above.This thus device (that is, " nothing Imitate telecontrol equipment ") one of example, and technical staff will extend this introduction and in the most wide aspect for this exposures using times What suitable lost motion device.

Device 100 includes the first axle 102 for being operably coupled to the first radome fairing actuating system 62A.First axle 102 can It is rotated with one or more components of the first radome fairing actuating system 62A, such as its second subtransmission 38A, so that first First axle 102 rotates after the actuating of radome fairing actuating system 62A.

Device 100 includes the second axis 104 for being operably coupled to the second radome fairing actuating system 62B.Second axis 104 can It is rotated with one or more components of the second radome fairing actuating system 62B, such as its second subtransmission 38B, so that second The second axis 104 rotates after the actuating of radome fairing actuating system 62B.

First axle 102 can rotate around axis A and terminate at flange 112 (that is, radial relative to axis A) radially In, flange 112 includes the component or pawl 114 of two axially extensions.Similarly, the second axis 104 can be around axis A rotation and end It terminates in flange 122 radially, flange 122 includes the component or pawl 124 of two axially extensions.

Device 100 further comprises intermediate module 130, the form for the flange that intermediate module 130 also extends radially and It can be rotated around axis A.Intermediate module 130 include configured to after the rotation of first and second axis 102,104 respectively and axially A plurality of components 132,134 that the component 114,124 of extension is cooperated.

In normal use, first axle 102 and the second axis 104 usually with the rotation of phase same rate and will rotate identical amount. Therefore, the component 114,124 of the axially extension of first and second axis 102,104 will all contact the cooperation on intermediate module 130 Component 132,134 and makes intermediate module 130 with substantially the same rate rotation and rotate substantially the same amount.It can be because of One and the differentiated friction power of the second each in radome fairing actuating system 62A, 62B (for example) undergo small difference.For example, if One axis rotates in finite time section is for example faster than another axis, then driving will be conducted via device 100 to another axis.Once axis (if situation is such) is rotated with identical speed, driving will will be no longer conducted with the rotation of substantially the same rate and therefore.

In order to realize this, driving can conduct the gearbox out of the ordinary into second subtransmission 38A, 38B from device 100 In, second subtransmission 38A, 38B can respectively configured to will reception it is any driving or torque be added to from motor 16 and connect Any driving of receipts or torque, so that second subtransmission 38A, 38B serves as the driving from 16 reception of device 100 and motor Summing junction.Radome fairing actuating out of the ordinary system can be conducted through from the driving that device 100 receives by second subtransmission 38A, 38B The various assemblies of system 62A, 62B are to activate the radome fairing out of the ordinary in radome fairing 60A, 60B.

Therefore, in various embodiments, device 100 allows radome fairing 60A, 60B to pass through the equal amount along length of travel (for example, each other in a straight line) actuating, although different radome fairing actuating systems 62A, 62B may undergo difference during between at this moment Frictional force.

After one of first and second radome fairing actuating system 62A, 62B person or another one failure, first axle 102 and One of two axis 104 person will no more be under the control of motor 16 and/or brake 20, and will rotate freely without restriction. This can prevent from being unfolded when the radome fairing of such as suspection is packed up, or be exposed to high speed gas in radome fairing (or other assemblies) Lead to the expansion being not intended to or mobile in the case of stream.In this case, according to this exposure, in first axle 102 and the second axis 104 Another one can will driving conduction to device 100, and also prevent undesirable movement.

For example, first is whole if the second axis 104 stops being driven because of the failure of the second radome fairing actuating system 62B Stream cover actuating system 62A will be operated and be continued the first axle 102 of driving device 100.During axially the component 114 of extension will contact Between cooperation component 132 on component and make its rotation.Cooperation component 134 on intermediate module 130 will then drive the second axis 104 The component 124 of upper axially extension.Therefore, driving will conduct between first axle 102 and the second axis 104.

Meanwhile if the second radome fairing 60B is exposed to high-speed flow, this may cause the second axis 104 of device 100 rapidly Rotation.However, this rotation will be prevented by device 100, because will connect with the component 124 of the axially extension of 104 rotation of the second axis Touching cooperates component 134 and then by the driving of first axle 102 (or prevention).Since first axle 102 is maintained at motor 16 and/or braking Under the control of device 20, therefore the second axis 104 will be driven by identical as first axle 102 in a manner of via device 100.

The configuration of Fig. 2 can be carry out various modifications to realize appropriate device for any specific application.

For example, shown device 100 is included in the operation of device 100 to conduct driving between first axle 102 and the second axis 104 Relative travel is about +/- 150 degree of device before.Also that is, if one of the component 114 of axially extension of first axle 102 Person contacts in the first Angle Position with one of cooperation component 132 person, then (assuming that intermediate module 130 is kept fixed) axially extends Component 114 will need to rotate about 150 degree to contact another cooperation component 132.It can be by the portion of mobile axially extension Part 114,124 and/or the position for therefore cooperating component 132,134, or component and/or the cooperation of the axially extension of addition additionally Component modifies this angle.It can set during installation between the component 114,124 of axially extension and cooperation component 132,134 Angle.In addition, this angle is identical for each set of the component 114,124 axially extended, but in first axle 102 it Axially the component 114 of extension and the component 124 of the axially extension on the second axis 104 can be different.

The aspect of this exposure extends to the gas turbine engine for incorporating above-mentioned trhrust-reversal device actuating system, and further prolongs Extend to the aircraft for incorporating gas turbine engine or trhrust-reversal device actuating system.

Although this exposure has been described with reference to various embodiments, those who familiarize themselves with the technology be will be understood that, can not depart from as The various changes of form and details are carried out in appended claim in the case where the scope of the present invention of elaboration.
