Abstract
The paper considers the issue of the production of hollow axles for railway transport; it adduces
the advantages of such axes in comparison to solid axles. The article describes the elaborating
technology of manufacturing the hollow axes on the basis of the screw rolling and radial forging
operations with the main stages of production. There also presented the results of experimental axes
manufacturing at PJSC “Motovilikha Plants” from the hollow blanks obtained by the method screw
rolling at JSC “Vyksa Steel Works”. There were conducted the mechanical tests of samples for
tensile and impact strength. The comparative results of mechanical tests with the existing
requirements for solid axles are presented.
