Abstract

Aspects of the disclosure are directed to a gas turbine engine shaft, having an outer circumferential surface (406) that circumscribes a central axis. The gas turbine engine shaft may comprise a plurality of splines (402, 403, 404) extending along a portion of the outer circumferential surface (406), where each of the plurality of splines (402, 403, 404) comprises an axial face (408, 409, 410) that tapers from the outer circumferential surface (406) to a spline top surface (412, 413, 414) and includes a curved chamfered surface (416, 417, 418) at a radially distal end of the axial face (408, 409, 410). The plurality of splines (402, 403, 404) may further comprise a first sidewall and a second sidewall separated by a first spline width distance (W; 420) along the outer circumferential surface (406), where the first and second sidewalls taper inwardly from the outer circumferential surface (406) to a second spline width (W) along the spline top surface (412, 413, 414) where the second spline width distance (W) is less than the first spline width distance (W; 420).
