THE DESIGN OF RAILWAY AXLES AND LOCOMOTIVE CRANK PINS

Tendencies toward increase in speed have focussed attention on modifications in present axle proportions. High-speed locomotives require corresponding considerations, particularly in the proportioning of locomotive crank pins. The object of this paper to set forth various aspects of loading conditions and stress limitations. A comparison of various methods of axle proportioning has been made with the suggestion of a new interpretation of loadings. Present methods of axle proportioning and an analysis of the division of the loading into various components are given; some consideration is given to stress concentrations and endurance limits of the material. Some characteristics of the nature of dynamic loadings is given, based on simplification of various conditions met in actual operation.
