    专利说明:

    The invention relates to a machine ’structure, namely to elastic-damping couplings, and can be used to operate in shock loads.
    A clutch is known comprising two half-couplings concentrically mounted with a radial clearance and having openings evenly spaced around them, a toroidal elastic element arranged. between the half-couplings and connected to them by means of non-expanding threads of connecting ropes, passed through ._ with a gap in the holes of the half- ' 5 couplings £ 1].
    A disadvantage of the known coupling is the low service life due to the breakage of the connecting ropes. jq
    The purpose of the invention is to increase the service life.
    This goal is achieved due to the fact that the elastic-damping coupling, containing two concentric 25 but mounted with a radial clearance half-coupler with holes made in them, evenly spaced around the circumference, a toroidal, elastic element placed between 3Q half-couplings and connected with them, by means of non-stretching threads of connecting ropes passed with a gap into the holes of the coupling, it is provided with intermediate elastic elements with holes for the rope’s threads, coaxially in the coupling half with openings for the threads of Anatov made holes for intermediate elastic eluents installed in the holes of the coupling halves, and each thread of the connecting rope is placed in the holes of the intermediate elastic elements.
    The intermediate elastic elements may be made of an elastomeric material.
    In addition, the intermediate elastic elements can be made in the form of flat metal springs bent along the contour of the holes in the coupling halves with the formation of a loop-like section in the middle part under the rope thread.
    In Fig. · 1 shows a side view of the coupling / in Fig. 2 is a section AA in FIG. 1ί in FIG. 3 is a view along arrow B in FIG. 2, 'in FIG. 4 is a variant of a coupling with another embodiment of elastic elements, side view *, in FIG. 5 - ce i
    BB in FIG. 4; in FIG. 6 is a view along arrow D in FIG. 5 / in FIG. 7 section DD in FIG. 6.
    The coupling contains concentrically mounted inner half coupling 1 and outer half coupling 2, placed 5 between them a toroidal elastic element 3 and connected to them by threads 4 of the connecting rope, evenly distributed around the circumference. The strands 4 of the rope are formed by a connecting cable made of plastic, which is stretched through all the b holes provided for this in the flanges of the inner 1 and outer 2 coupling halves and through the toroidal 15 elastic element 3.
    In the outer coupling half 2, holes 6 are made for screws, with which the coupling is mounted on the drive shaft of the machine, not shown in the drawing. The inner coupling half 1 is mounted on the drive shaft.
    The holes 5 are made of such a size and shape so that the threads 4 of the rope, even at a maximum possible angle of torsion angle of the coupling, do not lie against its walls. Each rope thread 4 is supported in the opening 5 of the outer coupling half 2 by intermediate elastic elements 7 gg of elastomeric material located in the holes and is firmly held against axial displacement. The elastic elements 7 are inserted into the recesses 8 formed in the flanges of the coupling halves. According to the example 35 shown in FIG. 4 and 5, two strands 4 of a rope are supported on one elastic element 9. Each elastic element 9 is inserted into the flange of the coupling half 2. In the same way as the elastic element 7 in FIG. 2. The recesses 10 under 40 elastic elements 9 prevent a change in their position.
    The elastic element can be made in the form of a metal flat spring 11 (Fig. Bi 7), the shape of which 45 ensures fixation of the rope thread 4 in the circumferential direction, and thanks to the loop-like bending of the spring 11 in the zone of contact with the thread 4, it is held without pinching and 50 continued it in the form of a toroidal elastic element 3 without contact with the walls of the hole in the flange.
    When working in the main, the strands of the cables 55 transmit the torque from one half-coupling to the other, while the half-couplings 1 and 2 rotate relative to one another, the magnitude of this relative rotation depends, in addition to the stiffness of the toroidal elastic element 3, and on the length of the rope threads. The support of the rope threads on the elastic elements 7 or 9 provides alignment of the lengths of the threads and they are evenly loaded. Even with extreme loads and mutual rotation of the coupling halves, the threads do not contact the edges of the holes 5, which increases their service life.

    B-B in FIG. four; in fig. b - view along arrow G in FIG. 5 / in FIG. 7 shows the cross section dd in fig 6. The clutch contains concentric-mounted inner coupling half 1 and outer coupling half 2, a toroid-shaped elastic element 3 disposed between them and connected to them by means of threads 4 of a connecting rope evenly distributed around the circumference. The rope threads 4 are formed by a connecting rope of a mass layer that passes through all the holes b provided for this purpose in the flanges of the inner 1 and outer 2 coupling half and through the toroid-shaped elastic element 3. In the outer coupling half 2 there are holes for the screws with which the coupling is attached On not izppajfceHHOM on the drawing driven shaft ma. tires. The inner coupling half 1 is mounted on the drive shaft. The holes 5 are made of such a size and shape so that the threads of the rope 4, even at the maximum possible torsional angle of the coupling, do not adhere to its walls. Each thread 4 of the rope goes under the hole in the hole 5 of the outer coupling half 2 and is placed in the holes by intermediate elastic elements 7 of elastomeric material and is firmly held against displacement in the axial direction. The elastic elements 7 are inserted into the half-couplings of the recesses 8 made in the flanges. According to the example shown in FIG. 4 and 5, two strands 4 of the rope are supported on one elastic element 9. Each elastic element 9 is inserted into the flange of the coupling half 2. In the same way as the elastic element 7 in FIG. 2. The recesses 10 under the elastic elements 9 prevent the change of their position. The elastic element can be made in the form of a metal flat spring 11 (FIGS. B and 7), the shape of which ensures the fixation of the thread 4 of the rope in the circumferential direction, and due to the loop-like bending of the spring 11 in the contact zone with the thread 4 provides for its retention without pinching and its continuation in the form of a toroid-like elastic element 3 without contact with the walls of the hole in. flace When operating mainly, the threads of the ropes transmit torque from one coupling half to the other, with coupling half 1 and 2 turning one relative to the other, the magnitude of this relative turning depends, in addition to the rigidity of the toroidal elastic element 3, and on the length of the rope threads. Bearing the threads of the rope on the elastic elements 7 or 9 ensures the alignment of the lengths of the threads and they are uniformly loaded. Even under extreme loads and mutual twisting of the coupling half, the threads do not come into contact with the edges of the holes 5, which increases their service life. Claim 1. A spring-damping coupling comprising two coupling halves concentrically mounted with a radial clearance, with holes in them evenly spaced around the circumference, a toroid-shaped elastic element placed between the coupling halves and connected to them by means of non-expanding filaments of connecting cables missed with the gap in the coupling half holes, characterized in that, in order to increase the service life, it is provided with intermediate elastic elements with holes for the rope strands, in half-sleeves with Ba apertured under yarn ropes are provided with openings for the elastic intermediate elements, the latter are installed in the openings of the coupling halves, and each rope strand connector arranged in the apertures of the elastic intermediate elements.
