SYSTEM AND METHOD FOR COUPLING ROTOR COMPONENTS WITH A SPLINE JOINT

摘要

A system includes a rotary machine. The rotary machine has a spline joint coupling first and second rotary components. The spline joint has a male spline portion and a female spline portion. The male spline portion includes a first plurality of spline teeth spaced circumferentially apart from one another about a longitudinal axis of the spline joint. The female spline portion includes a second plurality of spline teeth spaced circumferentially apart from one another about the longitudinal axis of the spline joint. The first plurality of spline teeth and the second plurality of spline teeth extend axially along the longitudinal axis. At least one tooth of the first or second plurality of spline teeth has at least one groove extending crosswise relative to the longitudinal axis. The at least one groove is disposed at an intermediate axial position between opposite axial ends of the at least one tooth.
