Abstract
A thrust reverser is described that comprises a new type of locking means for locking an actuator in position so that maintenance can be performed on the machine. The locking means comprises a removable locking device for preventing movement of an actuator. The locking means may also function in one configuration as an end cap. An actuator is also described comprising a removable torque limiting device for limiting torque of the actuator.
Claims9
An actuator and a removable locking device for preventing movement of said actuator,
- said actuator comprising a drive spline for moving said actuator, said drive spline having a hollow shaft with an inner surface;
- and
- said locking device comprising a first end and a second end with a shaft having an outer surface extending between said first and second ends:
- wherein said inner surface of said hollow shaft of said drive spline is sized and shaped to receive and mate with said outer surface of said shaft of said removable locking device to thereby prevent movement of said actuator when said shaft of said locking means is positioned within said hollow shaft of said spline.
An assembly including:
- an actuator having a drive spline for moving said actuator, said drive spline having a hollow shaft with an inner surface;
- and
- a removable torque limiting device for limiting torque to said actuator, said torque limiting device having a shaft extending therefrom, said shaft having an outer surface;
- wherein said hollow shaft of said drive spline is sized and shaped to receive and mate with said shaft of said removable torque limiting device to thereby limit torque of said actuator.
A method for locking and preventing movement of an actuator, said actuator comprising a drive spline for moving said actuator said drive spline having a hollow shaft with an inner surface, said method comprising:
- providing a removable locking device said locking device comprising a first end and a second end with a shaft having an outer surface extending between said first and second ends;
- and
- inserting said shaft at said first end of the device into said hollow shaft of said drive spline;
- said hollow shaft being sized and shaped to receive and mate with said shaft of said removable locking device to thereby prevent movement of said actuator.
A method for limiting torque of an actuator, said actuator comprising a drive spline for moving said actuator said drive spline having a hollow shaft with an inner surface, said method comprising
- providing a removable torque limiting device comprising a shaft extending therefrom, said shaft having an outer surface;
- inserting said shaft at said torque limiting device into said hollow shaft of said drive spline;
- wherein said hollow shaft is sized and shaped to receive and mate with said shaft of said torque limiting device to thereby limit torque of said actuator.
