    专利说明:

    the center parts are mutually held together by means of an outer sleeve which is anchored at one end to the second center part and which at its other end is rotatably arranged relative to the first center part, a pipe part is arranged inside the swivel device to cover a gap between the first center part and the second the center part, a first axial plain bearing is arranged between the outer sleeve and the first center part, the first axial plain bearing comprising a plain bearing element, and a second axial plain bearing is arranged between the first center part and the second center part.
    Embodiments of the swivel device according to the present invention are defined in the appended independent claims.
    With a solution according to the invention, a swivel device is obtained which is cheaper to manufacture as the present swivel device does not comprise a hole connection according to the prior art. This means that manufacturing and component costs for seals can be reduced. In addition, the service life increases.
    Furthermore, the inner surfaces of the outer sleeve with a device according to the present invention can be slightly coarser as no seals are to slide against them anymore, which means further reduction in manufacturing costs.
    Further advantages of a swivel device according to the invention are that fewer seals reduce the risk of leakage, and furthermore the assembly of the swivel device becomes easier because said seals have proved difficult to mount.
    Additional advantages and uses will become apparent from the following description.
    Brief Description of the Figures In the following, exemplary embodiments of the invention will be described with reference to the accompanying figures, in which: Figure 1 shows in longitudinal section an embodiment of the present invention; and - gur 2 shows the embodiment according to g. 1 in perspective view.
    Detailed Description Figs. 1 and 2 show an embodiment of the present invention. The i G. 1 and 2 comprises a first center part 20 and a second center part 30 and an outer sleeve / interconnecting part 150 acting between said parts 20, 30.
    The first center part 20 comprises a circular center hole 21 and in this example has a threaded fixed portion 22 for mounting a first connecting hose (eg a hydraulic hose) via a coupling device. Further, the first center portion 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 facing away from its end portion comprising the fixed portion 22. 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 corresponding to the center hole 21 of the first center part 20, and in this example has a threaded fixed 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 fixed portion 32. The second center part 30 further has an internally 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. The sleeve / tube 40 bridges a gap 50 which occurs between the end portions 123 and 131. As shown in Figure 1, the sleeve 40 has a dimension which is substantially the same as the dimensions of the center holes 21, 31 of the first and second part. the gap 50 is covered, which is very advantageous from the axial load point of view because the pressure medium can not exert compression of the end portions (end planes) 123 and 131. The sleeve 40 may, for example, be made of stainless steel and the first center portion 20, the second center portion 30 and the outer sleeve 150 may be made of steel which is rust protection treated by hardening.
    Between the sleeve 40 and the recesses 124 and 130, seals 41, 42 are arranged 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 sleeve. first and second center portions so that the sleeve 40 is rotatably arranged relative to the first 20 and second center portions according to one embodiment. According to another embodiment, the sleeve 40 is rotatably arranged relative to the first 20 or the second center part, i.e. attached to any of the first 20 or 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. Also the end portions 123 and 131 at the gap 50 are arranged to absorb axial forces in certain load cases and serve as a second axial sliding bearing 190.
    According to the present invention, the first axial plain bearing comprises a (axial) plain bearing element 141. The purpose of the plain bearing element 141 is essentially to absorb the axial forces of the swivel device.
    According to another embodiment, which is also shown in G. 1, the plain bearing member 141 is a separate member and made of a material other than the first center portion or the outer sleeve 150.
    It has been found that polymeric materials are particularly suitable with good properties, but metal also works well. The advantage of plastic is that it is very cost-effective and easy to manufacture plain bearing elements from this material.
    According to another embodiment, the plain bearing element 141 is detachably (replaceable) arranged at the first axial plain bearing 140. The advantage of this is, for example, that the plain bearing element 141 can be replaced in the event of wear.
    Furthermore, the plain bearing element 141 runs along the outer circumference of the first center part 20 at the first axial plain bearing 140, which is also shown in Figs. 1.
    The swivel device further comprises a circular outer sleeve 150 with nut function arranged to hold together the components of the swivel device 10 as shown in Figs. The outer sleeve 150 has two circular ledges 151, 152 and a shoulder 153 arranged between them.
    The plain bearing element 141 is arranged between the shoulder 153 of the sleeve and the shoulder 121 of the first center part.
    At its first end 154, the outer sleeve 150 further has a recess for a seal 156. At its second end 157, the outer sleeve 150 has an internal thread 158 which cooperates with the thread portion 132 of the second center part 30 so that suitable tightening can take place. The outer sleeve 150 has an external key grip 159.
    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 which thus also form a first and a second radial bearing at the ledges 120 and 122 respectively. The location of the first axial plain bearing 140, and thus also the plain bearing member 141, affects the first and second the “size” of the radial bearing because a displacement of the first axial sliding bearing to the left in Figure 1 means that the size of the first radial bearing decreases (or disappears completely) alt. a displacement of the first axial sliding bearing to the right in g. 1 reduces the size of the second radial bearing.
    According to the embodiment shown in G. 1, the first axial sliding bearing is positioned so that the first and second radial bearings are relatively equal in size to obtain balance when radially loading the device 10.
    According to the inventive construction concept, the swivel device 10 is very easily rotated.
    Sealing grooves are arranged on the outside, which is simpler from a manufacturing and assembly point of view. 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 performed. This is especially true for the plain bearing member 141 which is once lubricated during mounting at the first axial plain bearing 140.
    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 scope is not limited to what is shown and described, but changes and modifications are of course possible within the scope of the appended claims.
