13. The assembly of claim 12 wherein said first tooth is attached to a sleeve.
14. The assembly of claim 12 wherein said tooth attaches to a second rotor.
15. The assembly of claim 12 wherein the first cover is urged against said rotor if said first tab is disposed behind said second tab.
16. A coverplate for use with a rotor, said coverplate comprising:
a plate like body,
a plurality of teeth extending radially inwardly from a central opening in said body, and
a thickened area axially and radially adjacent said teeth.
17. The coverplate of claim 16 wherein said first cover has a gap between adjacent teeth thereof, said gap angling axially forward and radially inwardly from an aft surface of said cover.
18. A method of assembling a coverplate and a rotor comprising the steps of:
providing a first rotor for use in a rotating gas turbine engine, said rotor having a first plurality of tabs mounted thereto said first tabs having a first gap disposed between each adjacent first tab;
providing a first cover having a plurality of second tabs mounted thereto said second tabs having a second gap disposed between each adjacent second tab;
maneuvering said first tabs through said second gaps or said second tabs through said first gaps, and
rotating said cover relative to said hug to align said first tabs and said second tabs axially.
19. Said method of claim 18 further comprising:
filling said first gap or said second gap such that said first tabs may not rotate circumferentially relative to said second tabs.
20. Said method of claim 18 further comprising:
filling said first gap or said second gap such that said first tabs may not rotate circumferentially relative to said second tabs nor may said cover move axially away from said rotor.
The claims below are in addition to those above.
