COUPLING (VERSIONS) Russian patent published in 2014 - IPC F16D3/64 F16D3/56 

FIELD: machine building.

SUBSTANCE: coupling comprises two half-couplings and a resilient intermediate element connected to the half-couplings and fitted by side flanges and a fold coupled by the central part. According to the first version the resilient intermediate element is made from one flat spring fitted by a central part and at least four symmetrically set side flanges made solid with the central part and folded in respect to the central part. The adjacent flanges are folded in the opposite directions and their ends are fitted by the sections to be attached either to the half-couplings or to another resilient intermediate element or to an intermediate disc. According to the second version the resilient intermediate element is made as a set of two flat springs each having a central part and at least four symmetrically set side flanges made solid with the central part and folded in respect to the central part. The adjacent flanges are folded in the opposite directions and their ends are fitted by the sections to be attached either to the half-couplings or to another resilient element or to an intermediate disc. Gaskets from vibration damping material are installed between the flat springs.

EFFECT: lower noise and vibration of the coupling at its operation along with the simultaneous increase of the range of compensation characteristics at radial, axial and angular displacement of the ends of the shafts being coupled.
