    (54) HINGE JOINT
    This invention relates to synchronous rotating swivels having cuffs of elastic material. A swivel joint is known, with a holding intermediate separator and a sealing sleeve of elastic material, made in the form of a corrugated tube, fixed respectively on the driving and driven members of the swivel joint l3. The disadvantage of such connections is their unreliable operation due to the large load of the cuff, especially in its middle part and in the places of attachment, and a large distance between the places of attachment, which leads to a malfunction of the synchronous hinge. The aim of the invention is to increase the reliability of the swivel. The solution to this problem lies in the fact that the swivel separator is provided with at least one support fastened to the middle part of the cuff. The middle part of the cuff may be made of a material that is different from other parts of the cuff, for example a metal sleeve. It is also advisable to connect the concave surface of the separator support, made in the form of a protrusion, without axial movement to the convex surface of the additional protrusion, which serves as a control part and is itself an additional support and has an executive fastener for the cuff. When performing a swivel joint in the form of a double hinge, in which the outer body is set in motion, the hinge joint has an internal common part of the hinge, as well as two separators, it is advisable that the middle part of the cuff on the support (protrusion) of both the first and second separators compounds. In the case of using a swivel joint with a movable hinge lyft, the middle part of the cuff may have at least one fastening on the inner surface of the cuff-movable ring. FIG. 1 shows a sliding synchronous swivel with the cuff attached to the separator support and to the control part (the cuff consists of one part); in fig. 2 shows a variant of a sliding synchronous swivel with a sliding ring for holding a two piece cuff; in fig. 3 is a variant of a sliding synchronous swivel, similar to that shown in FIG. 2 (the cuff consists of one part); in fig. 4, an immovable synchronous swivel with fastening the cuff to the separator (the cuff consists of one part) in FIG. 5 - double synchronous swivel with cuff fastening on both separators directed to one another (the cuff consists of one part); in fig. 6 is a synchronous swivel connection controlled by ball guides that run parallel to the axis of the hinge and have a spherical bottom (the cuff consists of one part); Wah FIG. 7 is a variant of a synchronous rotating swivel, made in the form of a slide in a hinge, in which the separator is controlled by balls arranged in intersecting guides (the cuff consists of one part); in fig. 8 variant of sliding synchronous articulated joint (cuff consists of two parts);
    The sealed synchronous swivel 2 (Fig. 1), sealed by the cuff 1, consists of the outer body 3 of the hinge (driven part), the inner body 4 of the hinge and the separator 5 containing the balls, as well as the control part 6. The outer .3 and inner 4 body the hinge has parallel axes of the groove for the ridges 7. The separator 5 has an outer spherical surface 8, which is located in the corresponding internal concave spherical surface 9 of the outer part of the hinge. The separator 5 also contains a support, made in the form of a protrusion 10 with a hollow sphere in which there is a control part 6, having an additional protrusion and an outer spherical surface 11. The centers of the outer spherical surface 8 and the floor of the separator's sphere are located on both sides of the plane containing centent balls 7, at the same distance from her. The inner body 4 of the hinge can move relative to the control piece b and the separator or the outer body 3 of the hinge in the axial direction.
    The cuff 1 is made so that it, starting from the place of its fastening
    12 on the outer body of the 3 hinge, first passed to the point of fixing
    13 on the support of the separator 5 fold 14, which serves only to perceive the bend between the outer body
    3 hinges and a separator 5 at the joint turning point of M., and therefore corresponds to a half bend angle. From the fixing point 13 on the support of the separator 5, the cuff extends to the fixing point 15 on the control part 6 (additional protrusion) in the form of a fold 16. This fold also serves to perceive only a half bend angle made by the hinge inner body 4 with respect to the separator 5 at the joint turning point M. The inner body 4 of the hinge performs a sliding movement in the axial direction with respect to the control part 6. Therefore, the cuff from the fixing point 15 on the part 6 passes through several clamps 17 to the fixing point 18 on the rod 19 of the inner hinge body 4.
    The one-piece consisting of the cuff 1 is held, therefore, between the fixing points 12 and 18 on the leading and the driven parts 19 and 3 in the two fixing points 13 and 15 on the protrusion (support) of the separator 5 and the control part b (additional protrusion) ,
    The sliding synchronous swivel device of FIG. 2 is similar to the device of FIG. 1. At the same time the cuff consists of several parts. A metal sleeve (sleeve) 21 is fastened to the outer body 20 of the ball. A ring, which is adapted for clamping, holds in its outer circumference an annular part of the cuff, rounded inward towards the outer body of the hinge. The inner ring-shaped end of the annular cuff is fixed on the support (protrusion) of the separator at the fixing point 22. For this, the annular cuff has, for example, a thickening that is gripped into the corresponding groove of the support of the separator 23 and held by the clamping ring 24. At the same time, at the fixing point 22, the metal sleeve is held ( sleeve) 25, which extends in the axial direction of the hinge and has an attachment point 26 at the end for gripping part 27 of the cuff. The cuff portion 27 also consists of only one arcuate fold, which serves to overlap the bending angle of the inner body 28 of the hinge relative to the separator 23. The fold 27 passes into the section connected to the sliding (movable) ring 29. The sliding ring 29 can move along the rod 30 the inner body 28 of the hinge in the axial direction. From this section, a further part 31 of the cuff is folded. This part serves to block the glide path. The cuff portion 31 is attached at its end 32 to the stem 30, for example.
    clamping ring or other similar way. The cuff portion 33 therefore serves to close and seal the free space between the outer hinge portion 20 and the separator 23. Therefore, it perceives the half bend angle of the hinge. The metal sleeve 25 has a length designed for the sliding path of the inner body 28 of the hinge relative to the separator 23 or to the outer body 20 of the hinge. The second fold 27 serves to overlap the bending angle
    between the inner body 28 of the hinge and the separator 23. This angle corresponds to half the total bending angle. The sliding ring 29 is intended only to hold the cuff parts 27 and 31 against the action of centrifugal forces and, in addition, divides the cuff segments 27 and 31. into an area that serves only to perceive a bend, and an area that serves only to perceive a sliding path .
    The cuff of FIG. 3 is made of one. Parts. Section 33 of the cuff between the outer body 34 of the hinge and the separator 35 has a thickening 36 located in the corresponding groove of the outer body 34 of the hinge. The cuff portion 33 is held by the sleeve 37, which is pulled over the cuff 33 and pressed into the bulge 36 in the groove, the sleeve 37 is held on the outer body 34 of the hinge fixed axially with a depression 38, which enters the groove in the outer body 34 of the hinge. The cuff is also held on the support (protrusion) of the separator 35. For this, it has a thickening 39, which is located in the recess of the protrusion of the separator 35.
    At the site of this place of attachment, a metal sleeve 40 is pulled over the thickening 39, which holds the cuff 33 on the support (protrusion) of the separator 35 and, moreover, protects it. Starting from the bulge 39, the cuff moves away from the separator 35 and then passes backwards with an arc bend. At the end, the cuff has a protrusion 41 that is slid over the rod 42 of the inner body 43 of the hinge and is held between two flanges. Man 33 is held in this area. on the rod 42, the clamping strip 44, Couplings 37 and 40 serve as protection against dirt and flying stones. Due to separation and consolidation one by one. Couplings 37 and 40 on the outer body 34 of the hinge and the separator 35 axial bore holes of these couplings can be relatively small, since each of them should be designed only for half the bend angle. Therefore, protection against the penetration of foreign bodies, such as pebbles, etc., is improved.
    The cuff 45 (FIG. 4) consists of a single part for a non-movable swivel with relatively large bending angles. The separator 46 is provided with a funnel-shaped bell 47, the solution angle of which is approximately equal to the bending angle. This socket acts as a support (protrusion) of the separator. The cuff 45 is thickened at one end and held in the groove of the outer body 48 of the hinge by means of a draw strap 49 or the like. Further, the cuff 45 is held by the tightening band 50 in a groove or recess in the outer circumference of the socket 47 of the separator 46.
    in the area of its open end. In addition, the cuff 45 is fixed and sealed with a tightening tape 51 on the inner body 52 of the hinge or on its stubble.
    FIG. Figure 5 shows a dual hinge synchronous seal. The double hinge consists of two single synchronous rotating hinges 53 and 54, similar to the hinge of FIG. 1, however, are designed as fixed hinges. In this case, the supports of the separators 55 and 56 are equipped with additives 57 and 58, which can lead one another. Both synchronous rotating hinges have a common internal body 59. The cuff 60 overlaps the free space between the driving and driven portions. In this case, for example, the outer body 61 of the hinge is the leading, and the outer body 62 of the hinge is the driven part of the synchronous hinge. The same can be used for double hinges without mutual centering of the separators to each other.
    The cuff is provided with a rim 63, which is hooked into a groove in the outer body 61 of the hinge. In addition, the cuff is held with a tightening strap 64 or other similar means. From this point of fastening, the cuff extends in the form of a fold to the next point of attachment on the support of the separator 55 of the synchronous hinge 53, where the spring belt 65 is located in the section of the folded recess of the cuff, which presses the cuff into the recess of the separator, this first fold should perceive the external bend The hinge bodies 61 with respect to the separator 55. The subsequent fold serves to overlap the mutual bending portion of both separators with respect to each other. The cuff is held on the separator support 56 d The synchronous hinge 54 is also provided with a spring band 66 which presses the cuff into the groove 67 around the separator circumference. At the other end, the cuff is fixed and sealed on the outer body 62 of the hinge of the synchronous hinge 54 using the rim 68 of the cuff and the corresponding groove around the outer body of the hinge pulling ribbon 69.
    FIG. 6 shows a seal with a one-piece junction 70 of a synchronous retracting swivel (non-moving hinge) with tracks parallel to the axial direction, the bottom of which extends in the direction of the tracks in an arcuate manner; moreover, the centers of the radii are shifted on the axis of the hinge one in relation to the other so that, when the hinge is bent, the separator 71 is guided by balls held in the tracks at a half bend angle. The separator 71 is located at this type of hinge between the spherical outer surface of the inner body 72 of the hinge and the concave spherical inner surface of the outer body 73 of the hinge. The separator has a funnel-shaped bell 74 (similar to the bell of FIG. 4), which acts as an abutment (protrusion). The cuff is held between the anchoring points 75 and 76 on the outer body of the hinge and the core 77 belonging to the inner body of the hinge at the outer end in the socket groove 78 of the clamping ring 79. The cuffs are designed so that they can follow the curves that occur between the anchoring points.
    FIG. 7 shows a cuff 80 for a synchronous rotary swivel, in which the torque-transmitting balls are located in the tracks, and. these paths in the axial direction of the hinge in pairs converging in pairs or diverging, the tracks of the inner body 81 of the hinge and the outer body 82 of the hinge mutually intersect. The separator 83 is controlled by the balls 84 at a half bending angle and moves halfway along the slide as the inner body of the hinge moves relative to its outer body. The convex outer surface of the separator 83 is guided by the cylindrical-inner surface of the outer body 82 of the hinge. The cuff is pulled over the area of its larger diameter to the outer body of the hinge and is held by the edge 85 in the corresponding groove of the hinge body 82 using tightening tape 86. From this fixing point, the cuff 80 departs first with an approximately constant diameter away from the outer body 82 of the hinge, then narrows is arcuate and has a protrusion 87 directed toward the separator, by which it is caught into the groove of the extension 88 of the separator 83, which acts as a support for the separator. In this area, the cuff is pressed against the spring separator.
    tape or other similar means 89. From the protrusion 87, the cuff extends further away from the separator with a reduced external diameter, returns arcuate and tapers to a passage diameter that corresponds to the external diameter of the hinge rod 90 belonging to the internal body Si. Here the cuff is also inserted by the edge 91 into the groove the rod 90 and fixed clamping tape 92.
    For the embodiment shown in FIG. 8, a synchronous rotating swivel joint is provided with a cuff made of two parts 93 and 94. The synchronous rotating swivel joint is designed as a sliding swivel joint. It has an outer hinge body 95 provided parallel to an axis with circumferential paths. In the cylindrical inner cavity of the outer body 95 of the hinge there is a separator 96 containing balls 97, which can slide in the cavity with its convex outer surface. Next, the separator 96 has an internal concave spherical surface, with which it is adjacent to the spherical outer ghrhrannosti internal body 98 of the hinge. The separator 96 and the inner body 98 of the hinge are mutually immovable in the axial direction. The first part 93 of the cuff must be able to perceive the bend between the BHeaiHHM body 95 of the hinge and the separator 96, as well as the path of their mutual slip. The cuff part 93 is held at one end on the outer circumference of the external body of the hinge with the help of the rim 99 and the groove in the external body of the hinge, as well as the tightening tape 100. At the other end, part 93 of the cuff is fixed on the coupling 101 by a thickening 102 and a clamping tape 103. Coupling 101 required to overlap the slip paths in order to form appropriate folds in the cuff part 93. A fold in close proximity to the rim 99 serves to perceive the bend between the outer body of the hinge and the separator 96, while lying down near the thickening 102, the folds are perceived and the “- leveling movement of the separator 96 in relation to the outer body 95 of the hinge.
    The cuff portion 94 serves to seal between the separator 96 and the inner body 98 of the hinge and must equalize only distance changes resulting from bending of the separator 96 relative to the inner body 98 of the hinge. For this, the cuff part 94 is held by the rim 104 in the support groove in the hollow inner space of the separator using a clamp ring 105. In addition, the cuff part 94 is held by the other edge 106 using a tightening strap 107 in the groove of the hinge rod 108 belonging to the inner body 98.
    The hinge joints made in this way are reliable and work, since the large load on the cuff is reduced, especially in its middle part, and the distance between the cuff attachment points is reduced, which prevents breakage.
