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

FIELD: machine building.

SUBSTANCE: coupling comprises two half-couplings and a resilient element made as two sets of single-type elements. Every single-type element comprises a central part, a middle part and a peripheral part coupled to each other by the central parts. The peripheral part is aimed at the attachment to the half-coupling or to the intermediate element, the middle part is formed by the side element made solid with the central part and folded in respect to the central part in one direction in each set. Side elements of a single-type element from each set are folded in the opposite directions. According to the first version the single-type element is made as a flat spring and the side element of the single-type element is made as two symmetrically set side flanges, each of the latter is communicated with the mating section being the peripheral part of the single-type element. According to the second version the single-type element is made as a flat spring and the side element of the single-type element is made as two symmetrically set side flanges, each of the latter is communicated with the mating section being the peripheral part of the single-type element. Gaskets from vibration damping material are installed between the single-type elements in each set.

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