| Abstract: | The failure modes and causes of railway bearings in shaft boxes are analysed, and the measures for enhancing bearings life are systematically elucidated ban the viewpoint of material, manufacturing technology, lubrication and seal, as well as structure optimization. Followings are recommended for railway bearings:vacuum degassed GCr18Mo, auperfinishing, EP lubricants and lshrinth seal, increase in roller's diameter, inclined rib and spherical roller end, rollers with cenver generant,bollow rollers and deep hole rollers. |
