    A resilient shaft coupling that, to transmit torque, includes an annular intermediate member made of rubber disposed between an inner rigid coupling part and an outer rigid coupling part. The intermediate member has, on its outer periphery, pinion-like rubber teeth that mesh, with provision for axial movement, with companion inner teeth of the outer coupling part. The radially inner zone of the intermediate member is embodied as a member of uniform torsional strength. For radial support of the projecting portions of the outer zone, at least one closed metal ring is embedded in the rubber concentrically of the rotational axis near the radially inner interface of the zone and near each of the axial outer surfaces. The rings are preferably in the form of cables made from wire strands. To further increase the transmissible torque, the rubber of the outer zone is harder than the rubber of the inner zones. With this kind of arrangement of the metal rings, the endangered axially terminal annular zones are given effective radial support, so that in the axially central core zone of the intermediate member the rubber can still be urged outwardly by centrifugal force and, after overcoming the noraml clearance, can press the teeth firmly into the inner teeth of the outer coupling part.

    In her P 1, an annular rubber intermediate element (KRPE) 4 with an outer gear 5, which meshes with the internal gear 3 and outer O2, is vulcanised. KRPE4 is profiled with the formation of the inner equal strength of the curling section (U) 6 with the thickness of the short, transitioning U 7 and outer U 8 with a constant thickness equal to the thickness of the КРПЭ А with its inner diameter, КРПЭ 4 is equipped with at least two

    This invention relates to elastic couplings with an intermediate element in the form of a monolithic annular rubber element.
    The aim of the invention is to increase the reliability of operation of a coupling having a high torsional elasticity.
    Fig, 1 shows the coupling, axial section; fig 2 is the same, view rboku.
    The elastic coupling contains a concentric inner crawling coupling 1 in the form of a hub and an outer coupling half 2 with an internal gear crown 3 and a ring rubber intermediate element 4 with an external gear crown 5, which engages with the internal gear crown 3 of the external half coupling fixed to the internal half coupling. 2 with the possibility of axial movement. The annular intermediate 1st) 1st element 4 is made profiled with the formation of the inner equal strength of the curling section 6 with a thickness reducing to the periphery, a short transition section 7 and an outer section 8 with a constant thickness equal to the thickness of the ring element 4 according to its inner diameter
    With such an arrangement of the intermediate element 4, when transmitting large torques, there is a danger of bending radially inward of the axially protruding ends of the outer section 8, since they protrude over

    the inner section 6, which may cause the elastic teeth of the outer ring gear 5 to pop out from the depressions of the inner ring gear 3 of the outer coupling half 2. To prevent this, the ring intermediate element 4 is provided with at least two reinforcing metal rings 9 and 10 of circular cross section. The rings 9 and 0 are located concentric with the axis of rotation inside the outer section 8 of the intermediate element 4 near its end surfaces and the transition section 7,
    The rings 9 and 10 serve as a radial support for the axially protruding ends of the outer section 8 and thus prevent them from being folded up with increasing. torsional moment. As shown in FIG. 1, the rings 9 and 10 are located at a sufficiently large axial distance from one another, so that the central zone of the elastic intermediate element 4 remains free and thus, during operation of the coupling, the rubber material under the action of centrifugal force can be pulled out freely and, therefore, appropriate pressing of the teeth made of rubber of the outer crown 5 into the cavities of the internal gear crown 3 of the outer half-coupling 2 can occur.
    Each reinforcing ring 9 or 10 is made primarily of me.

    hop strings, woven in the form of a cable. The joints of multiwire cables are evenly distributed around the circumference. Due to the multitude of wires in such rings, there is no danger of failure as a result of breaking like a massive ring. Made of multiwire strand ring. Compared to a massive ring with a smooth surface, it has a significantly larger surface and thus, during vulcanization, it gives rubber, which can penetrate into the gaps between the multiwire strands, a large working surface and a sticking surface. Metal O-rings have a low mass, so that even with a high cyclic loading of the drive, there are no undesirably large accelerating forces that can cause the metal ring to break out of the rubber.



    ability to ensure reliability, 25, the annular gap between the outer section 8 of the annular precision element is equipped with at least an intermediate element 4 made of rubber of higher hardness than the sections 6 and 7. At the same time, the torsional elasticity of the coupling for the shafts does not decrease, since it is mainly determined by the properties of softer rubber of the inner zone (sections 6 and 7) of the elastic intermediate element 4.
    For a certain size coupling
    The rubber hardness of the inner portion 6 and the transition portion 7 may be, for example, about 45 hardness. According to Shore A, and the outer portion 8 may be about 75 Shore A.
    Torque is transmitted, for example, from coupling half 1 through an intermediate ring rubber 4 to coupling half 2.
    Through the proposed implementation of the intermediate element provides
