HINGE COUPLING Russian patent published in 2012 - IPC F16D3/16 F16D3/48 

FIELD: machine building.

SUBSTANCE: hinge coupling includes two semi-couplings located with a gap between end surfaces and connected by means of axial spherical hinge. Spherical hinge is formed with the first element with spherical tip, which is installed on one semi-coupling, which is located in centring cavity of the second element installed on the other semi-coupling. Coupling is equipped with peripheral spherical hinges made similar to axial spherical hinge and located about axial spherical hinge so that centres of spherical hinges lie in bisector plane of the angle formed with end surfaces of semi-couplings. Elements of each peripheral spherical hinge are pressed with springs towards the centre of that hinge, and one of the elements is pressed with spring towards the hinge centre in axial spherical hinge.

EFFECT: providing transmission of high torque moments and simplifying the coupling manufacture.
