    The invention relates to a swivel device, in particular designed to connect two pipes or hoses rotating relative to one another, wherein the device (10) includes a first centre part (20) provided with a hole and comprising a fastening portion (22) for the attachment of a first pipe, the device (10) includes a second centre part (30) provided with a hole and comprising a fastening portion (32) for the attachment of a second pipe, the first centre part (20) and the second centre part (30) being rotatable relative to one another. The centre parts (20, 30) are held together by means of an outer sleeve (150) anchored at one end to the second centre part (30) and at its other end arranged in a rotationally slidable manner relative to the first centre part (20). A first axial sliding bearing (140) is arranged between the outer sleeve (150) and the first centre part (20) and a second axial sliding bearing (190) is arranged between the first centre part (20) and the second centre part (30). The first centre part (20) is axially displaceable between a first position in which the first axial sliding bearing (140) is operative and a second position in which the second axial sliding bearing (190) is operative.

    专利说明:

    The first center part 20 comprises a circular center hole 21 and has a threaded fastening portion 22 for mounting a first connecting hose via a coupling device. Furthermore, the first center part 20 has a circular first ledge 120 which merges via a shoulder 121 into a circular second ledge 122 which terminates with an end portion 123. The ledge 122 has a circular recess 124 at its end portion 123. The first center part 20 also has a key grip 28 to facilitate assembly.
    The second center part 30 comprises a circular center hole 31 and has a threaded fastening portion 32 for mounting a second hose via a coupling device.
    Furthermore, the second center part 30 has a circular recess 130 in its end portion 131 facing away from the fastening portion 32. The second center part 30 further has an externally arranged threaded portion 132. Furthermore, the second center part 30 has a key grip 39 to facilitate assembly.
    According to the invention, a circular sleeve or a circular tube 40 is arranged in the recesses 124 and 130 as shown in Fig. 1. The sleeve / tube 40 bridges a gap 50 which occurs between the end portions 123 and 131. The sleeve 40 causes the gap 50 to be covered, which is very advantageous from the point of view of axial load because the pressure medium cannot exert compression of the end portions (end planes) 123 and 131. Seals 41, 42 are arranged between the sleeve 40 and the recesses 124 and 130 to prevent the pressure medium from reaching the gap 50. The seals 41, 42 are arranged in external grooves in the sleeve / tube 40. The sleeve 40 cooperates slidably with surrounding portions 124 and 130 of the first and second center portions.
    Furthermore, the swivel device 10 comprises a first axial sliding bearing 140 which is arranged to absorb axial forces of the swivel device. The end portions 123 and 131 at the gap 50 are also arranged to absorb axial forces in certain load cases and serve as a second axial sliding bearing 190.
    A circular outer sleeve 150 with nut function is arranged to hold together the components of the swivel device 10 as shown in Fig. 1. The outer sleeve 150 has two circular ledges 151,152 and a shoulder 153 arranged between them. At its first end 154 the outer sleeve 150 has a recess for a seal 156 At its other end 157, the outer sleeve 150 has an internal thread 158 which cooperates with the thread portion 132 of the second center portion 30 so that proper tightening can occur. The outer sleeve 150 has an external key grip 159.
    A radial hole 170 is provided in the first center portion 20. The hole extends between the center hole 21 and the periphery of the second ledge 122. The hole 170 is arranged to supply pressure medium and lubricate the axial bearing 140. Seals 180 and 181 are arranged in external grooves on each ledge in the first center part 20, the seals 180, 181 acting between the first center part 20 and the outer sleeve 150.
    The seals 180, 181 are positioned so that the hole 170 and the axial bearing 140 are located between the seals as shown in Fig. 1.
    An annular recess 171 is provided within the outer sleeve 150 to facilitate pressure media communication between the hole 170 and the axial bearing 140. An annular groove 172 is provided on the first ledge 120 of the first center portion 20 at the axial bearing 140.
    There is a plain bearing function between the peripheral surfaces of the ledges 120 and 122 and opposite ledge surfaces of the outer sleeve 150. The sleeve 40 also participates in the rotational movement.
    At pressure medium load, an axial force F1 arises which strives to reduce the size of the gap 50 and at the same time increase the axial gap of the sliding bearing 140. The aforementioned occurs due to the diameter difference that occurs between the ledges 122 and 120.
    The hole 170 and the seals 180,181 and relevant gaps ensure the intended pressure medium influence. A pressure area A1 which causes the formation of the force F1 is defined by the area difference between the ledges 122 and 120. The force F1 can at most move the first center part 20 relative to the second center part 30 so that the end portions 123 and 131 abut each other so that the gap 50 ceases.
    Furthermore, during pressure medium loading, an axial force F2 arises which strives to increase an axial gap 200 between the second center part 30 and the sleeve 40. Actual pressure area A2 is defined by the diameter of the recess 130. The pressure area A2 gives rise to the force F2 which can move the first center part 20 the second center portion 30 so that the axial bearing 140 becomes gap-free. The seal 42 ensures the intended pressure medium influence.
    The axial forces F1 and F2 can be selected by changing the pressure areas A1 and A2 so that the desired resultant force is obtained. Thus, through dimensional variations, one can select a desired mode of operation of the swivel device 10. In doing so, one can also take into account external axial forces which affect the swivel device 10 in its application environment.
    It is thus possible to select different normal positions for the swivel device 10 from dimensioning the pressure areas A1 and A2 so that the forces F1 and F2 become equal in size to the forces just mentioned being different in size. In a preferred embodiment, F1 is chosen slightly larger than F2, among other things with regard to external loads.
    One can thus also choose which of the axial sliding bearings 140 and 190 is to be most active.
    According to the construction concept according to the invention, the swivel device 10 becomes very easily rotated.
    All sealing grooves are arranged externally, which is simpler from a manufacturing and assembly point of view. According to the invention, the seals which insulate the pressure areas are arranged at three different diameter levels. It should be understood that the number of seals can of course be varied as needed. In connection with the assembly of the swivel device 10, of course, the necessary greasing of the components is carried out.
    Furthermore, it should be understood that the design of the components of the swivel device 10, such as for example the fastening portions, can of course be widely varied within the scope of the present inventive idea.
    The invention is not limited to what is shown and described, but changes and modifications are of course possible within the scope of the appended claims.
