    专利说明:

    The invention relates to mechanical engineering, namely to synchronous rotation hinges. A synchronous, rotational hinge is known, comprising a casing with a sphere. The outer surface without protrusions and longitudinal grooves on it, as well as balls placed in the grooves of the housing and the inner element and enclosed in a separator. However, the known hinge has insufficient load capacity at the maximum permissible angle of deflection due to the absence of stops in the housing and sector. The purpose of the invention is to increase the load capacity of the hinge at the maximum permissible angle of deflection. This goal is ensured by the fact that the hinge of synchronous rotation, comprising a housing with a spherical cavity and longitudinal grooves, an internal element installed inside the cavity with a spherical outer surface and longitudinal grooves on it, as well as balls placed in the grooves of the body and internal element and enclosed in a separator, equipped with lugs located on the housing and the separator with the ability to interact with each other at the maximum permissible angle of deflection. In this case, the stop in the housing can be made in the form of a protrusion on a spherical surface having a bearing surface located concentric with the axis of rotation, and the stop in the separator is located on its end face and is made in the form of a surface of rotation. In addition, the stops in the separator and the housing can be made in the form of elastic elements, for example, in the form of a cup, coil or force spring, as well as in the form of a block of elastic forming synthetic material. Moreover, the outer diameter of the spring is equal to the diameter of the base of the spherical segment with the radius of the ball equal to the radius of the spherical surface of the inner element, and the emphasis in the body can be made in the form of a ring placed on the spherical surface concentric with the axis of rotation. Figure 1 shows a hinge of synchronous rotation with a thrust surface in the outer hinge element, a longitudinal section; figure 2 - the same, with the maximum angle of the elements; FIG. 3 shows a hinge in which the abutment surface lies in the area of the housing bore; figure 4 is a hinge, in which a spring is fixed on the thrust surface of the housing; on: Fig.5 - a hinge in which the spring is fixed on the separator; Fig. b - a hinge in which the elastic element is made in the form of a block of artificial material; figo has a hinge in which a spring is fastened to the separator; Figures 8 and 9 show embodiments of a disc spring.
    The hinge consists of an outer element 1 having a cavity 2 and an axis 15 of rotation 3. On the inner wall of cavity 2 along the circumference there are grooves or grooves 4 extending parallel to the axis of rotation 3, In cavity 2 there is an internal element 5, 20 whose outer surface has longitudinal grooves or grooves b. The inner element 5 and the drive shaft 7 are made of one piece. On the spherical surface 8 of the controllable element 9 installed as a separate structural part on the inner element 5, a separator 10 with a hemispherical cavity is installed. The centers 11 and 12 of the outer sphere 8 and the internal cavity of the separator 10 are located on opposite sides of the plane passing through balls 13. Separator 10 contains windows 14 distributed around its circumference, in which balls 11 are held, serving to transmit torque, which are also located in two opposite grooves or grooves 4, and b) Nogo hinge member 1 and the inner casing 40 Shar Virno element 5. In order to seal the cavity 2 serves bellows 15 as a bellows.
    On the wall of the cavity 2 of the outer 45 hinge element 1 there is a thrust surface 16 concentric with the axis of rotation 3, on which the separator 10 rests with its support surface 17 at a maximum angle of inclination.
    In ONE of the constructive variants, the stop surfaces 16 are located in the hole zone of the outer element 1 and the bevel is formed by its end edge. The support surface 17 of the separator 10, which interacts with the stop surface 16, is located with a thinner cross-sectional side of the separator 10, and simultaneously serves . increase static strength 60.
    In another constructive embodiment, the separator 10 rests on the spring 18 connected to the outer element 1 through the protrusion 19. then the role of the supporting plate 65
    surface 16 performs conical surface 20.
    In addition, in one embodiment, the spring 21 may be fixed to the separator 10 by means of the locking element 22, then an annular surface 23 is provided in the outer element 1 as the thrust surface, in which the spring 21, when the hinge is deflected, reaches the stop 16.
    The spring force varies and depends on the type of hinge. So hinges with a large shift and a large tilt angle require greater loading than hinges with a small shift.
    The elastic element 24 can also be made in the form of a block of elastic forming synthetic material which annularly covers the protrusion 19 of the outer spherical element 1. When bending the hinge, the conical surface 25 of the separator 10 pushes against the spring element and compresses it. Due to the compression of the elastic element 24, the separator 10 has an oppositely directed force.
    On the separator 10, a spring spring 26 can also be attached, which rests on the ring 27 located on the outer element 1 in the form of a separate structural part, on the surface of which the bearing surface 16 is made.
    The hinge can also be made in the form of a up-hinge. These are the hinges in which the balls 13 are controlled by a separator 10 c. the plane passing through the bisector of the angle of inclination. It is necessary that the separator has an inner and outer spherical surface, the mid-points of which would not be identical with the midpoint of the hinge.
    The spring plate 26 can be filled in various shapes, for example, it includes slots 8, which are radially distributed around the circumference from the outside to the inside, and in this design, the spring 26 can only be bent on the corresponding parts in this hinge design.
    Tray spring 26 can also be made in the form of a solid disc without cuts.
    The use of the disc springs 26 on the separator 10 is preferable, since the separator only produces half a tilt angle, resulting in a small constructive space.
    The hinge works as follows
    At the maximum angle of inclination of the inner element 5, the separator 10 due to an abutment not in the distance co. perform further rotational motion, so that the balls 13 in the initial part of the slope lie in the plane
    29, which is located at a smaller angle to the central axis of the inner element 5 than to the plane of the bisector 30. When the inner element 5 is further tilted, this angle becomes even larger than the half angle between the central axes of the inner and outer elements, so that the centers of the balls lie flat bone 31, the angle between which and the central axis of the inner element 5 is greater than the angle between the angle bisector of the angle and the central axis of the element 5.
    Due to the manufacturing gap between the parts, the hinge has a tendency for the plane containing the centers of the balls 13 to move with increasing angle. scrap of inclination in the direction of the plane 29. This plane in the form of a circle moves with a further angle of inclination of the hinge due to the VOLUME that the separator 10 during its swinging rotation is attached by its supporting surface 17 to the parts of the circumference of the supporting surface 16 in the direction of the plane in which the theoretical bisector 30 lies and then in the direction of the plane 31.
    In this position, the balls 13 are pressed back from the edge of the groove to its base, and thereby an increased maximum permissible load of the hinge occurs, as a result of which, when the hinge bends, the support passes approximately at an angle of 20-23 °. At a certain bend angle, the conical surface 20 abuts completely and the spring 18 can no longer bend.
    The invention allows to increase the load capacity of the hinge at the maximum angle of inclination due to the fact that when the angle of inclination is slightly lower than the maximum, the separator abuts against the stop, as a result of which the inclination of the internal hinge element further takes half the angle of inclination between the inner and outer hinge elements. This achieves a load-independent return of the balls to the plane of the bisector of the angle of inclination and perfect synchronous rotation.
    Making the abutment elastic makes it possible to create a force acting in the opposite direction with respect to the tilting moment, which facilitates the control of the hinge.
