摘要： A rotary railway coupler (10) is provided having compound fillets (94, 96) of variable increasing radii of curvature inserted between the shank (84) and the butt end (54) of the coupler (10). The compound fillets (94, 96) reduce the stress concentration between the shank (84) and the butt end (54) of the coupler (10) by distributing the stress over a greater curved surface area in order to decrease the possibility of fatigue cracking and failure at the transition surface between the coupler shank (84) and butt end (54). The compound fillet (94, 96) may also be arranged to undercut the surfaces (78, 80, 86, 88) of the coupler shank (84) and butt end (54) in order to reduce metal build-up at this location.
