    Flexible shaft coupling has a crown of spokes, of which alternatively one spoke is connected to the driving shaft have body and the next is connected to that of the driven shaft. Between the spokes are rubber units filled with a damping substance and which transmit the peripheral forces, and which become deformed elastically when an unequal directional torsion of the have body takes place. The rubber units (31, 38) on both sides of the spoke (11) have hollow spaces (41, 41') which are of variable volume, and which are in contact with each other through opposed passages (91) through the spoke, the passages being opne or fitted with valves and providing a flow resistance to the damping substance.

    The invention relates to mechanical engineering.
    Known elastic couplings containing two popumufta connected by elastic elements located between the end tabs of the coupling half 1.
    The disadvantage of these couplings is low damping capacity and greater stiffness.
    Also known is an elastic coupling comprising two coupling halves with protrusions and rubber elements with chambers interconnected 2.
    This device is closest to the invention by its technical essence and the effect achieved.
    However, the disadvantages of this coupling are the large size and low reliability.
    The purpose of the invention is to reduce the size and increase the reliability of the coupling.
    This is achieved by connecting the chambers of the rubber elements through openings made in the walls of the chambers. The holes are also filled in the protrusions of one or both coupling halves, and the rubber elements have vulcanized metal plates with bent off
    the ends placed in the grooves made on the ledges of the coupling half. Rubber elements can be cylindrical and are screwed springs vulcanized into their walls. The chambers of the rubber elements can be divided by radial steaks into two chambers, and vulcanized to the projections of one klk of both coupling halves. The half-coupling protrusions are also made in the form of fingers half-couplings parallel to the axis, and the rubber elements with chambers with box-shaped parts vulcanized at their ends with holes for the half-couplings. A valve may be installed in the opening of the protrusion of one of the coupling halves. The clutch can be equipped with a disk with holes for fingers, and the chambers are formed by jumpers between the holes and fingers of the coupling halves, while the holes connecting the chambers are made in the disk or in the pe3jmoBbix elements. Rubber elements can be vulcanized onto the Fingers and provided with a vulcanised ring sheath, and the rubber element can be made with protruding sheaths.

    FIG. 1 shows a coupling with two fitted with protrusions (spokes) coupling half and placed between the spokes filled with pressurized rubber elements with cameras, the cross-section; in fig. 2 - the same, longitudinal section; in fig. 3 rezovy element of the coupling; in fig. 4 - coupling, in which the elements are vulcanized to the protrusions of one of the coupling halves and form a rubber-metal element; in fig. 5 - cut sho metal element; in fig. 6 - rubber element with box-shaped parts that are navulcanised at the ends; in fig. 7 - the same section; in fig. 8 - rubber element subjected to shear; in fig. 9 - rubber element mounted between two protrusions; in fig. 10 — coupling with chambers formed by radial ridges between the holes and the coupling half fingers, cross section; in fig. 11 - coupling, longitudinal section; in fig. 12 - rubber element with an annular shell, longitudinal section; in fig. 13 is the same cross section; in fig. 14 - coupling with rubber elements, longitudinal section.
    The coupling consists of a half-coupling 2 fitted with a mounting flange 1 with four protrusions (spokes) 3, as well as a half-coupling 5 equipped with a fixing flam 4 with four spokes 6. The spokes 3 are located between the spokes 6 and fixed on the half-coupling 2 which is integral with the flange 1 4 and backspace No. 1 6 are fixed at the end 8 of the half-coupling 5 by means of welds 9 and 10. Between the spokes 3 and b there are eight rubber elements 11 equipped with metal plates 12 with hollow chambers 13 and 14 filled with liquid. The rubber elements 11 are in an unloaded state NII coupling (f ig. 2) have a square cross-section with strongly rounded corners, and hollow chambers 13 and 14 have a circular cross-section. The rubber elements P before assembly are identical to the rubber element (Fig. 3), which, together with plastics 12 and plates 15, forms a vulcanized rubber-metal part, the length of which in the circumferential direction in the free state is larger than that after assembly of the coupling. The plates 15 and on their outer surface are covered with rubber film 16 and have protruding edges 17.
    The spokes 3 and 6 are made with axial grooves 18, in which the folded edges 17 and the plates 15 are inserted so that the plates 15 of the rubber elements I are pressed tightly against the surface of the spokes 3 and 6 and fixed against shear. One of the spokes is provided with a lockable filling opening 19, from which a cavern 090094 passes to the throttle opening 18
    20. Plates 12 can be provided with holes 21, which serve only to connect all hollow chambers and to fill with liquid from hole 19. Rubber element 11 is provided with a reinforcing wall of hollow chambers 14 and 13, a vulcanised helical spring 22, and a needle 6 - having a choke hole, freely moving with a limited stroke valve 23, which
    10 can compensate for high-frequency oscillations of small amplitude of hollow chambers 13 and 14 without fluid exchange in order to prevent the transmission of high-frequency oscillations, in particular sound vibrations from one machine
    5 to another. The rubber element 11 may have constrictions 24 and 25 of the chambers 13, which with increasing pressure increase in the circumferential direction. When turning the half coupling 2 relative to the half coupling 5 in a clockwise direction, one of the spokes 3 approach the spokes 6, the others are removed, while the volume of some chambers 13 and 14 decreases, while the volume of others increases. As a consequence, fluid is exchanged between each chamber located adjacent to the spoke through the throttle holes 18 in the corresponding direction, while an increased pressure is established in one of the chambers due to the flow resistance of the throttle hole 18.
    Half coupling 26 (FIG. 4) is formed with
    the hole 27 and the keyway 28 by a ring 29 with three spokes 30. On the side surfaces of the spokes 30 rubber elements 31 and 32 vulcanized, the free ends of which, when pressed, fit snugly to the side surfaces of three wedge-shaped spokes 33 with through holes 34, which include fingers of the second half coupling. The rubber elements 31, 32 are provided with chambers 30 and 36 separated from each other by the spokes 30. The spokes 33 are made with throttle holes 37. The spokes 33 have protruding edges 38 on both sides, preferably of box shape, which hold the ends of the rubber elements 30- 31 and fix them from shear.
    FIG. 5 shows rubber elements 31 and 32 with chambers 35 and 36 before assembly. Sleeve 26 and rubber elements 31 and 32
    (Fig. 4) before assembling the coupling form a rubber-metal element with openings 39 between the rubber elements.
    The elastic element (Fig. 6) consists of a box-shaped tip 41 having a hole 40
    a rubber element 42 with a chamber 43 and with a sleeve 44 inserted therein. 45. On the other hand, the rubber element with a camera is provided with a cam lug 46. The tip 41 consists of walls surrounding the rubber element 42, the outer surface of which is provided with sealing tongue of the bottom 47. The tip 46 consists of a base 48 vulcanized onto a rubber element, located on the other side of the rubber element, the surface of which is provided with a sealing tongue and outwardly directed walls 49. Nako The nose piece 41 is smaller than the tip 46 and enters it, while having an orifice 50 having an intermediate β-plate 51 may be located between the bottom 47 and the bottom 48.
    Connecting the lugs 41 and 46 with each other, the finger 52 can be inserted into the hole 40 and fixed by means of a nut 53, while the finger 52 is sealed by the thickenings 54 and 55 of the hole 40. The rubber-metal elements connected in this way (Fig. 6) form a collar ring, into the sleeves 44 of which the fingers 52 of the second half-coupling, not shown, can be inserted. The pitch circles of the sleeves 44 and of the openings 40 and the loosely rubber-metal element are made larger than the corresponding pitch circles of the coupling halves. When assembling the coupling ring with the floor of the coupling and the diameter of the coupling ring, it can be reduced by means of the tension tape until the pitch circles match. Then bolts can be inserted and the rubber elements 42 of all three rubber-metal elements are pre-tensioned.
    The vulcanized rubber element 56 (FIG. 8) is formed by an outer metal casing 57, an inner metal casing 58 and a rubber disk 59 with parallel cross-section and has a through chamber 60. The casing 57 is provided with a rubber-coated flange 61, and the casing 58 is equipped with a rubber-coated flange 62 arranged parallel to the flange 6.
    In the assembled state (Fig. 9), the rubber element 56, the flanges of which remain parallel, is squeezed between two wedge-shaped spokes 6. and b4, with the rubber disc 59 in cross section taking the shape of a rectangle, the rubber element 56 fits snugly to the side surfaces The spokes 63 and 64 and through the protruding edges 65 and 66 are fixed from the bridging mix (and. The spoke 64 is made with a throttle hole 67 that connects the hollow chamber 60 with the hollow chamber of an adjacent, symmetric rubber element. The finger 63 has one finger 68 the coupling half and the needle 64 has a hole 69 for the finger of the second coupling half. The first coupling half 1 63 is rigidly connected to each other by means of an annular disk, for example, by welding, the second coupling half spokes 64 do not come into contact with the circular disk 70 and are connected to each other by an unexposed lying in front of the drawing plane of the annular disk.
    The clutch (FIGS. 10 and 11) is provided with a disk 72 having six holes 71, into which six rubber elements 73 are inserted. The fingers 74 connected to the rubber elements 73 are fixed on the flange 75 of the coupling half 76,
    having a hole 77 for the shaft. A coupling half 79, having an opening 78, is connected through a flange 80 by means of a sleeve 72 of a coupling 72 of a finger 82 with a coupling 72 of a coupling 72 fixed to it and inserted into an opening 81 of a coupling 72, and between the holes 71 of a wall 83 of a disk 72 form the spokes of a half coupling 79. In a central opening 84 The clutch disc 72 can directly enter both the master and the driven shafts, and the disc will simultaneously be a half clutch.
    The resist elements 73 can be inserted into the holes 7 and prestressed relative to the surface of the holes 6. They can also be connected to the surface of the holes. The rubber elements 73 in the circumferential direction on both sides of the finger 74 have chambers 85 and 86, which are separated from each other by rubber bridges 87 and 88, and are closed by walls 89, 90.
    Holes 91. and 92 into rez} stitched jumpers 87 and 88 connect chambers 85 and 86. Hole 93 in wall 83 also connects chamber 85 to the chamber of an adjacent rubber element. For filling chambers 85 and 86 and for ventilation, ducts 94, 95 and 96 can be made. They are marked with a dashed line.
    With torsional vibrations of the half coupling 76 relative to the half coupling 79, the chamber of the rubber elements increases or decreases, and the damping fluid is exchanged between the chambers. The size and shape of the holes is chosen in such a way that the oscillations, especially with large amnituts, are completely attenuated, and the holes can be equipped with devices for regulating the resistance to the flow of fluid.
