HOLLOW SPHERICAL ROLLING ELEMENT Russian patent published in 2023 - IPC F16C33/00 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to the field of mechanical engineering, in particular to the production of bearings. The hollow spherical rolling body consists of an outer thin-walled shell with an inner cavity containing a power reinforcing structure. The outer thin-walled shell is made seamless. The inner cavity has the form of an inscribed regular or semi-regular polyhedron, on the edges of which flat force elements are built. The elements together form a cellular power structure, in which individual cells are a pyramid with a vertex located in the geometric center of the internal cavity.

EFFECT: increase in reliability is achieved.
