ADAPTIVE MODULAR BEARING ASSEMBLY Russian patent published in 2023 - IPC F16C19/54 

FIELD: railway transport.

SUBSTANCE: chassis of the rolling stock of railway transport. Design consists of kinematic, support and fixing modules. The kinematic module is made of two onboard inner rings with rolling elements capable of absorbing only radial forces and of stiff rings with rolling elements of thrust bearings capable of absorbing only alternating axial forces. The support module is a fixed hermetic shell of the bearing unit, made of a hermetic connection of fixed outer rings of bearings with short cylindrical rollers and free rings of thrust bearings with thrust flanges on the outer surfaces. The fixing module includes an adapter for fixing a wheel pair with adaptive modular bearing assemblies in the U-shaped axle box openings of the side frames of the freight car bogie.

EFFECT: creation of a sealed, reliable, easy to manufacture, assemble, disassemble and repair design of a modular bearing unit is achieved.
