  • Patent number: 11378126
    Abstract: The rolling bearing design incorporates at least two antifriction bearings, a fixed supporting centering sleeve and a toothed cage with an extended cylindrical part, extending outside the dimensions of the bearings, and sockets in the form of a crown on both sides of the cylindrical part of the cage. The fixed supporting centering sleeve of the cage incorporates channels for oil supply to the cage. The extended cylindrical part of the cage between the adjacent bearings in the assembly can be made up of two parts with the possibility to slip relative to each other. The invention enables improvement in the reliability, wear-resistance and durability of the bearing assemblies incorporating at least two bearings, including those of different types and sizes, which operate at high speeds and are subject to significant centrifugal loads exceeding the gravity acceleration by hundred times.
