Abstract
An example gear arrangement includes a gearbox shaft and a journal shaft. The journal shaft establishes an opening that receives an end portion of the gearbox shaft. The gearbox shaft is configured to rotate the journal shaft. The journal shaft is configured to selectively rotatably couple with another shaft. The journal shaft is allowed to align to the bearing surface while the gearbox shaft allows for misalignment between the accessory and gearbox drive.
Claims18
1) A gear arrangement, comprising:
- A gearbox shaft;
- and
- a journal shaft establishing an opening that receives an end portion of the gearbox shaft, the gearbox shaft configured to rotate the journal shaft, wherein the journal shaft is configured to selectively rotatably couple with another shaft.
8) A gas turbine engine gearbox arrangement, comprising:
- an output shaft;
- a gearbox shaft having a first end rotatably coupled to an accessory gearbox;
- and
- a journal shaft received over an opposing second end of the gearbox shaft, the journal shaft configured to rotate together with the gearbox shaft, the journal shaft further configured to selectively rotatably engage the output shaft to drive a rotor shaft of the gas turbine engine.
16) A method of rotating a gas turbine engine rotor, comprising:
- rotating a gearbox shaft;
- rotating a journal shaft with the gearbox shaft, the journal shaft received over an end of the gearbox shaft;
- and
- selectively rotatably coupling the journal shaft to another shaft to rotate a gas turbine engine rotor.
