Abstract
Two shafts 12, 14 are secured axially with bolts 58 through flanges 22 and 32. Coupling 42 is splined to the shafts and resists bending by interaction of bearing surfaces 46, 44, 48 and 50. Threads 66 on one end of the shaft and an inwardly extending flange 68 on the coupling provide a means for removing a shaft without placing axial loading on bearing 18. Either shaft may be removed while leaving the coupling 42 in place to protect the bearing compartment. Axial loading is taken by bolts 58, torque loading by splines 30, 40 and bending moment taken by the interacting surfaces.
