RUBBER-CORD CASING FOR HIGHLY ELASTIC COUPLING Russian patent published in 2008 - IPC F16D3/74 F16D3/68 

FIELD: mechanics.

SUBSTANCE: rubber-cord casing for highly elastic coupling has sidewalls for attachment to coupling halves and is made of rubber with reinforced criss-crossed layers of cord, enwrapping the side rings. Configuration of torous-shaped rubber-cord casing is defined by single radius in mean cross sectional diameter. Radii, profile linear dimensions, bore diameter, which define the rubber-cord casing scross section, relate to the outer diameter as follows: R1:D1=0.11±20%; R2:D1=0.08±20%; R3:D1=0.025±20%; R4:D1=0.015±20%; H1:D1=0.263±20%; H2:D1=0.163±20%; D2:D1=0.71±20%, where R1 - section outer radius, R2 - section inner radius, R3 - sidewall radius, R4 - fillet radius between outer radius R1 and sidewall radius R3, D1 - outer diameter of the rubber-cord casing, D2 - bore diameter of the casing, H1 - width of the casing cross-section profile, H2 - linear dimension between inner faces of sidewalls.

EFFECT: invention of rubber-cord casing and extended range of angular and axial displacement of shafts joined by the coupling.
