Abstract
A generator includes a drive gear mounted to a main rotor shaft though a drive gear bearing and an input jaw plate keyed to the drive gear for rotation therewith, the input jaw plate defines input jaws which selectively mesh with the disconnect jaws, the disconnect shaft axially movable in response to a disconnect system which axially separates input jaws and the disconnect jaws to permit relative rotation between a main rotor shaft and the drive gear through the drive gear bearing.
Claims10
A 4-Pole generator comprising:
- a generator housing which defines a flange;
- a drive shaft assembly supported within said generator housing;
- a main generator power section supported on said drive shaft assembly axially adjacent said flange;
- and
- a drive gear selectively connected to said drive shaft assembly through a disconnect system, wherein said disconnect system further comprises:
- a main rotor shaft which defines main shaft splines;
- a disconnect shaft which defines disconnect shaft splines and disconnect jaws, said disconnect shaft splines mate with said main shaft splines;
- and
- an input jaw plate keyed to said drive gear for rotation therewith, said input jaw plate defines input jaws which selectively mesh with said disconnect jaws, said disconnect shaft axially movable in response to a disconnect system which axially separates said input jaws and said disconnect jaws to permit relative rotation between said main rotor shaft and said drive gear through a drive gear bearing.
