| description | The main materials for the manufacture of rolling
stock bearing assemblies are steel ShKh15, ShKh15SG,
ShKh4. The article discusses the possibility of using
steels 20Kh2N4A, 95Kh18-Sh, 12Kh18N9T as alternative
materials, an assessment of the arising contact stresses
on the surfaces of the raceways of the bearing rings and
rolling elements is given. When using 12Kh18N9T steel, the maximum contact stresses are reduced by 4 % in
comparison with standard materials, which can provide an
increase in the resource of the bearing assembly. |
