    A torsionally elastic shock and vibration absorbing coupling, comprises first and second coupling parts which are adapted to be connected to the respective parts which are to be coupled together and which have coupling portions with openings therethrough. An annular resiliently deformable pressure cushion is disposed between the coupling parts with the openings and is connected to each part such as by vulcanizing. At least one substantially non-stretchable rope which passes through the receiving openings of the respective coupling parts overlie the cushion, and extend circumferentially along portions of the respective parts and, between the parts, to interconnect them. The rope is directed preferably in a wave configuration with portions extending circumferentially and portions extending radially with respect to the respective coupling parts, and they advantageously include wave crests which extend or project outwardly from the cushion so that they form projections which provide for increased air circulation during rotation of the parts.

The outer half coupling is provided on the outer surface with teeth that fit into the corresponding cavities located on the inner surface of the ring connected to the drive shaft. For the purpose of imparting to the coupling of protective properties, the teeth have undercuts at the base. In addition, the teeth are equipped with a covering layer or caps of synthetic elastic material. The clutch may be composed of two mirrored shells with semi-couplings. And, besides, an internal hole has been made in the inner coupling halves, through which cooling medium flows through the openings made in the shells.
    The method of manufacturing the coupling is characterized in that first the cable is pulled through the holes of the coupling halves, and then all parts are introduced into the mold for vulcanization, while the branches of the cable are placed in the corresponding cavities of the mold, and the mold is closed with a cover, the inner surface of which corresponds to the outer surface of the shell. The branches in the mold for vulcanization can be kept at the same distance by guide elements passing through the shell.

    The clutch contains an inner coupling half / flange, which is mounted on a shaft (not shown) of a driven or driven machine, and an outer coupling half 2 with a flange, which is fixed with screws on the flange of a driven or driven machine (Fig. 1-3 and Fig. 6 -13).
    Ring flanges coupling halves 3 to 4, connected to the master and slave shaft MM1, are located opposite each other (Fig. 4 and 5).
    The coupling flanges / and 2 or 3 and 4 are interconnected by an extensible connecting cable 5, for example
    from synthetic material, the branches of which are located on the perimeter at the same distance x each other from each other. The branches of the cable 5 are vulcanized with a shell-shaped cross section between the flanges 6 that is connected to the flanges of the coupling halves / -2 or 3-4 by means of vulcanization.
    Forming the outer surface of the shell 6 has the shape of a semicircle,
    therefore, the branches of the cable 5, when loaded with the clutches, intersect at a minimum.
    The branches of the cable 5 extend in the axial plane of the coupling and are formed by one or several cables, which one after the other are drawn through the holes in the coupling halves / -2 or 3-4 holes (Fig. 2). Cables in cross section can be round, flat or tape-shaped, while in the last
    In this case, a good connection of the cable to the shell is created.
    Branch; And cable 5 is so connected with the shell that the external surface of the shell has protrusions 7 of semicircular shape, which coincide with the branches of the cable, and depression 8 (Fig. 1-3).
    The protrusions 7 are formed on the inner surface of the shell 6 (Fig. 4 and 5).
    In shell 6 between the branches of the cable 5
    (Figs. 6 and 7) there are holes, directed radially from the center of the partition, for additional cooling of the cushion, from the inside. Holes 9 in the lower part (Phn. 7) are made round, and holes
    0 at the top - slit-like.
    Between the sheath 6 and the branches of the cable 5 there are vulcanized strips 1 / fabrics, the joints of which are displaced along the perimeter one relative to another.
    This eliminates the harmful transverse load in the shell 6 during operation.
    FIG. 10 two coupling halves of FIG. 1-3 types are combined into a block
    couplings in such a way that the coupling halves / are connected to the shaft, and the coupling halves 2 are fixed to the drive or driven flange | maschiny. In this embodiment, in the right side of the box, the flange of the inner coupling half, / is provided around the perimeter with a supporting flange 12, on which the skirt 6 is supported by a connecting cable or branches. Cables 5. In the left side of this embodiment, instead of the supporting
    flanged inner coupling half
    supporting parts 13 made of fabric are vulcanized.
    On the flanges of the inner 1 and outer 2 coupling halves are located the cams 14 and 15, which, when the coupling is overloaded, abut one another. The contacting areas of the cams are provided with a layer of rubber 16 to reduce impacts.
    The holes 17, through which the loops of the connecting cable 5 or its branches are drawn, are provided with sleeves 18 made of synthetic material to protect the cables from being pressed against the edges of the coupling (Fig. 13).
    Forming the contact surfaces of the shell with the coupling halves are inclined towards each other and form an obtuse angle, while the plane of the junction 19 forms an angle, and the plane of the junction 20: is the angle of 90 ° relative to the axis of rotation of the coupling (Figures 14 and 15).
    The branches of the cable 5 pass radially and are formed by one cable (Fig. 14-19) and two, cables (Fig. 20), which are pulled one after the other through the holes 17 in the coupling halves 1 m 2 (Fig. 15 and 20).
    The clutch (Fig. 20) is intended primarily for transmitting large, torques or for receiving strong shocks, in which the branches of the cable are arranged approximately in parallel, with the openings 17 for the passage of the cables in the coupling halves / u2 lying on circumferences of different diameters.
    Between the hole mi / 7 for the cable is made tangential connecting pipe 21 (Fig. 18 and 19).
    The bottom surface 22 of the connecting grooves 21 is made convex with a maximum radius of curvature, which creates favorable conditions for the operation of the connecting cable and at the same time allows it to be pulled through without perforations through the holes 17.
    The connecting cable, after being pulled through all the holes, is welded to the ends.
    For the manufacture of the coupling (Fig. 14) and the left side of the coupling (Fig. 17), the branches of the cable 5 are placed in the mold for vulcanization of the casing in the radial direction at equal distances from each other by a row of thin pins 23 that partially pass through the cavity forms and form holes in the finished shell, which serve to cool it.
    On the right side of the coupling (Fig. 17), the branches of the cable 5 in the mold cavity extend into box-shaped parts 24 laid out of synthetic material that is susceptible to vulcanization, while the properties of the back-end are held on the glue-coated radial struts 25, and the box-like parts remain in compressive pod. The branches of the cable 5 (Fig. 16) are so located in the shell 6 that it has a smooth outer surface, except for small holes from the pins 23.
    On the inner surface of the shell 6 (Fig. 15) there are radial rib-like protrusions 26 to increase the heat rejecting surface. In the shell 6 there are also vents 27 for ventilation.
    FIG. 20 two coupling halves of FIG. 14-19 types are combined into a coupling unit so that the inner space of the shells 6 is closed, and from the shaft opening 28 through the groove 29 and the slot 30 between the coupling halves 1, compressed air is supplied, which is partially released through the holes 27 in the shell 6 and partially slot 31 between the half couplings 2.
    FIG. 22 and 23, the outer half coupling 2 is provided with teeth 32, which are inserted into the corresponding pads of the ring 33 connected to the drive shaft.
    The tooth 32 (FIG. 23, right side) on the outer coupling half 2 is provided with a layer of elastomer 34 to eliminate noise and destroy the surface of the teeth.
    The tooth 32 (Fig. 23, left side) is provided with plastic caps 35 and, moreover, has undercuts 36 at the base.
    The coupling halves (Fig. 1-23) have a common axis 37. Through the holes 38 fi 39 in the coupling halves 3 and 4 (Fig. 4), the internal cavity 40 of the coupling is ventilated.
    Torque in the coupling is transmitted through the sheath 6 and the cables 5. The protrusions 7, the holes 9, 10 and 27, the groove 29 and the slots 30 31 increase the intensity of the cooling of the shell, increase the durability of the coupling and stabilize its characteristics. The tooth is limited by the elastic rotation of the coupling halves, and the rubber layer 16 cm thickens the blows of the teeth. The pins 23 and the box parts 24 simplify the manufacture of the coupling.
    The grooves 21 between the holes 17 and the sleeves 18 increase the durability of the cable. Undercuts 36 in the tooth x 32 give the coupling safety properties.
