the coupling ends for development road

摘要

An improved railway coupler shank design wherein the thickness T of the rear spherical wall of the butt and the minimum thickness t of the sidewalls are maintained in the relationship of T t. The improved coupler so designed causes a change in the force and moment distribution of the shank so that the proportionally stiffer and stronger rear walls resists a greater portion of the induced moment thereby providing a stress reduction in both the rear wall and the sidewalls. The relationship of T t also serves to reinforce the rear spherical wall of the butt thereby increasing its wearing characteristics.
