BS 8535:2011 PDF

1   Scope This British Standard specifies a design method for powered and non-powered axles with inboard bearings for railway applications. This standard:

• specifies the forces and moments to be taken into account with reference to masses, traction and braking conditions;

• specifies the stress calculation method for axles with inboard axle journals;

• specifies the maximum permissible stresses to be assumed in calculations for steel grades EA1N, EA1T and EA4T as defined in BS EN 13261 and steel grades A1N and A1T as specified in BS 5892‑1;

• specifies a method for determining the diameters for the various sections of the axle. It also gives recommendations for the preferred shapes and transitions to ensure adequate service performance.

This standard is applicable to:

• solid and hollow powered axles for railway rolling stock;

• solid and hollow non-powered axles of motor bogies;

• solid and hollow non-powered axles of locomotives; ...
