Abstract
A planet gear housing assembly in an epicyclical gear assembly comprises an aft planet gear assembly and a forward planet gear assembly. The aft planet carrier assembly comprises an aft flange defining a central aperture and an annular mounting flange positioned forward of and coaxial with said central aperture, said mounting flange forming a forward facing mounting surface comprising a curvic structure. The forward planet carrier assembly comprises a forward flange defining a central aperture and an annular mounting flange positioned aft of and coaxial with said central aperture, said mounting flange forming an aft facing mounting surface comprising a curvic structure. The curvic structures of the mounting surfaces are positioned relative to each other to thereby form a static curvic joint.
