FIELD: machine building.SUBSTANCE: sealing coupling includes a diaphragm connected to intermediate shaft that is movably connected to semi-couplings so that it can be rotated relative to semi-couplings, thus forming a line of self-rotation axis, which crosses a line of self-rotation axis of any semi-coupling; at that, maximum approximation of those lines takes place inside intermediate shaft.EFFECT: absence of sliding friction on the sealing surface.2 cl, 7 dwg |
