MULTI-ROW DISMOUNTABLE CHAIN FOR TRANSMISSION WITH SHROUD PULLEYS Russian patent published in 2019 - IPC F16H7/06 

FIELD: machine building.

SUBSTANCE: invention relates to the machine building. Multi-row dismountable chain for transmission with shroud pulleys consists of several single-row collapsible chains having stepped rollers equipped with fixing beads of increased length on the ends, for example, on one side, and identical plates having mounting holes and recesses on them, wherein radius of recesses is equal to radius of roller groove and distance between centers of recesses circles is equal to chain pitch. Fixing beads of one chain at installation are located in gaps between fixing collars of adjacent chains, at that number of rows should be even, and plates on side facets have ledges located on at least one their side, transverse axis of symmetry of plates.

EFFECT: higher smoothness of travel, besides, dismountable design of transmitting element facilitates maintenance, and availability of ledges on plates increases their adhesion coefficient with band.
