    This invention relates to elastic couplings. The purpose of the invention is to increase reliability. Essence: each elastic element is installed with gaps in the circumferential direction and is fixed on the annular surfaces of the coupling halves in contact with it. Elastic elements are provided with locking strips, on the surfaces of the coupling halves and elastic elements in the places of their contact longitudinal grooves are made, in which locking strips are located parallel to the coupling axis and fixed. The locking strips are vulcanised to elastic elements. The longitudinal grooves of the coupling halves and the sections of the fixing strips entering into them are made in the form of a dovetail. The clutch is equipped with flat limit rings with radial teeth. The gaps between adjacent teeth of the limiting rings are made larger in magnitude than the allowable displacements of one coupling half relative to the other in the circumferential direction. 6 hp f-ly. 2 Il.

    This invention relates to elastic couplings for connecting shafts.
    The purpose of the invention is to increase reliability.
    Figure 1 and 2 shows the proposed coupling.
    The elastic coupling contains two coupling halves 1 and 2, mounted concentrically. Radially located teeth 3 and 4, alternately engaging with each other, are made on mutually facing surfaces of the half couplings. Side surfaces 5-8 of teeth 3 and 4 are rotated relative to the axis of the tooth, the surfaces of 5 and 7 of the teeth are convex, and surfaces 6 and 8 are concave. The length of each tooth 3 or 4 corresponds to the width of the half-muff. The top of the tooth of one half-coupling is located near the annular surface 9 or 10 of the other half-coupling facing it. Between each of the two adjacent teeth of the three semi-couplings there is a cavity J1 with a longitudinal axis of symmetry parallel to the axis of the coupling. In each cavity I1 with a tension in the radial direction there is a rubber cylindrical elastic element 12, the length of which corresponds to the width of the coupling half. Each elastic element 12 is fixed with gaps in the circumferential direction and is fixed on annular surfaces 9 and 10 of coupling halves 1 and 2 that are in contact with it. Elastic elements I2 are provided with locking strips 13 and 14. On surfaces of coupling halves 1 and 2 and elastic elements in places their contacts are made longitudinal grooves 15 and 16, in which

    The locking elements of the bar 13 and 14 are arranged parallel to the coupling axis and fixed. The bars 13 and 14 can be vulcanised to the elastic elements 12. The longitudinal grooves 15 and 16 of the half couplings J and 2 and the portions of the locking bars 13 and 14 entering into them can be filled. in the form of a dovetail. Each elastic element 12 is made with a central hole 17, the axis of which is parallel to the axis. couplings. The coupling can be equipped with flat limiting rings 18 and 19 with radial teeth 20 and 21 installed at the ends of the coupling halves, with each end of one coupling half 1 or 2 having one limiting ring 18 or 19, the tooth 20 or 21 of which is located with . in the circumferential direction between the teeth of the restrictive ring of the other half-coupling. The gaps between adjacent teeth of the limiting rings are made larger in magnitude than the allowable displacements of one coupling half relative to the other in the circumferential direction.
    The torque is transmitted, for example, the sweat of the half-coupling I to the half-coupling 2 through elastic elements of 12 V, the initial moment of switching-on the coupling, the torsional rigidity is determined only by the si-. By LILAMs of shear, which occur during free deformation of elastic elements 12, Since these forces are relatively small, at the moment of start-up the clutch has an extremely low torsional gesture. There is no torque transmission at this time. After

    samples of gaps in the circumferential direction between the elastic element J2 and the side surfaces 5 and 7 of teeth 3 and 4 of the coupling halves I and 2, i.e. when the teeth of each pair are adjacent to the corresponding elastic element 12,
    the stress in the elastic elements varies from shear to compression. The stiffness of the elastic elements sharply increases, the thaws and the torque is transmitted.
    The teeth of the restrictive rings 18 and 19 are trapezoidal in shape, with the mutually facing teeth c forming a pair that bounds the cavity between the teeth of the half couplings.
    Such an embodiment of the coupling makes it possible to improve the working conditions of the elastic elements and increase the reliability of operation 20 of the structure.
