In July, Raymond J. Drago, P.E.—chief engineer of Drive Systems Technology, Inc. (DST), a mechanical power transmission consulting organization that he founded in 1976—will lead an IACET-accredited course on both the geometry and rating of involute splines of various types along with their applications. Topics under discussion include spline configuration variations, including half depth, full depth, and special function designs; both fixed and flexible spline configurations in terms of usage and design; lubrication methods, including grease, oil bath, and flowing oil, as well as coatings appropriate for various spline applications; and shear and compressive stress rating methods with analyses methodology in both equation and graphical methodology via various rating charts.
