Abstract
An example coupling stack includes a first rotating member and a second rotating member. A plurality of aligned slots is defined in the first rotating member and the second rotating member. A tab lock is provided having an annular body with an axial front side, an axial back side, and a radial inner periphery. Tabs are formed on the axial back side and inserted into the plurality of aligned slots. The annular body of the tab lock also includes a plurality of openings extending into the radial inner periphery. A plurality of flanges is provided on the axial back side of the annular body adjacent to the plurality of openings.
Claims15
A gas turbine engine comprising:
- a fan disposed about an axis;
- a compressor section axially aft of the fan and arranged to receive air flow from the fan;
- a combustion section axially aft of the compressor section and fluidly connected to the compressor section;
- a turbine section connected to the compressor section and arranged to drive the compressor section;
- and
- a coupling stack through which the turbine section drives the compressor section, the coupling stack comprising
- an input coupling connected to the fan;
- a tie-bolt;
- a plurality of aligned slots defined in the input coupling and the tie-bolt;
- and
- a tab lock having an annular body with an axial front side and an axial back side, the annular body including a plurality of openings extending into a radial inner periphery of the annular body, a plurality of flanges on the axial back side of the annular body adjacent to the plurality of openings, and a plurality of tabs, at least a portion of each tab inserted into one of the plurality of aligned slots.
