ROLLING BEARING BY NIKOLAY ZAGUTA (VERSIONS) Russian patent published in 2015 - IPC F16C19/22 F16C29/04 F16C13/02 

FIELD: machine building.

SUBSTANCE: rolling bearing with support surfaces, rolling bodies and a separator comprises a roller chain, and the roller chain comprises internal and connecting links with rolls and hollow rollers. Besides, rolling bodies of the bearing are made in the form of rolls with journals of the roller chain. Each internal link of the chain comprises two parallel rolls, arranged with their journals in at least one hollow roll on its diametrally opposite sides of the internal surface with the possibility of interaction with it. And each connecting link comprises mainly two parallel hollow rolls arranged with a gap relative to hollow rolls of two adjacent internal links. And so that inside the hollow rolls of the connecting link on diametrally opposite sides of the inner surface, with the possibility of interaction with it, there are journals of rolls of internal links placed. And a separator comprises hollow rolls of internal and connecting links of a roller chain, mounted with a gap relative to support surfaces, besides, the chain is made as closed. A rolling bearing comprising rolling surfaces, rolling bodies, a separator and a roller chain with internal and connecting links with rolls and hollow rollers. Rolling bodies are made as hollow rollers of internal and connecting links of the roller chain, each internal link of which comprises two parallel rolls, arranged with their journals in at least one hollow roll on its diametrally opposite sides of the internal surface with the possibility of interaction with it. And each connecting link comprises preferably two parallel hollow rollers arranged with a gap relative to hollow rollers of two adjacent internal links, so that inside hollow rolls of the connecting link on diametrally opposite sides of the internal surface with the possibility of interaction with it there are journals of rolls of internal links placed. And the separator is made in the form of rolls, for instance, internal links of this chain.

EFFECT: exclusion of sliding friction, which makes it possible to considerably expand spheres of use and eliminate application of lubrication, and to use for supports of rotating bodies and for supports of linear movements, possibility to use the device for critical conditions of operation.
