Abstract
An anti-rotation assembly may include a first shaft, a second shaft, and a locking sprocket. The first shaft may have a first crenelated end rim, the second shaft may have a second crenelated end rim, and the locking sprocket may be configured to engage the first crenelated end rim and the second crenelated end rim to anti-rotatably couple the first shaft to the second shaft. That is, the locking sprocket may be configured to prevent relative rotation between the two shafts. The anti-rotation assembly may further include an axial retaining ring configured to axially retain the locking sprocket.
Claims20
An anti-rotation assembly comprising:
- a first shaft comprising a first crenelated end rim;
- a second shaft comprising a second crenelated end rim;
- and
- a locking sprocket configured to engage the first crenelated end rim and the second crenelated end rim to anti-rotatably couple the first shaft to the second shaft.
A gas turbine engine comprising:
- a first shaft comprising a first crenelated end rim;
- a second shaft comprising a second crenelated end rim;
- and
- a locking sprocket configured to engage the first crenelated end rim and the second crenelated end rim to anti-rotatably couple the first shaft to the second shaft.
A method of assembling a gas turbine engine, the method comprising:
- engaging a locking sprocket on a first crenelated end rim of a first shaft;
- positioning a second shaft so that a second crenelated end rim of the second shaft is juxtaposed with the first crenelated end rim;
- and
- axially moving the locking sprocket to engage the first crenelated end rim and the second crenelated end rim.
