Definitions

  • the invention relates to a tilting bearing for the articulated transfer of heavy loads to a support, in particular for supporting a bridge superstructure on a support bench, with a bearing pot resting on the support and containing an incompressible deformable pressure mass, consisting of a pot base and a pot wall, and with one to be supported Load-bearing lid, which rests on the pressure mass and is sealed against the pot wall, a horizontal bearing connecting the pot bottom with the lid being arranged in the middle of the bearing pot, which has a bearing pin protruding from the pot bottom or the lid, which extends into a bearing recess engages the lid or the bottom of the pot, and a space is provided between the end face of the journal and the bottom of the bearing recess.
  • tilting bearings are used for the constraint-free transfer of large loads to a support.
  • the bearings have to transfer both vertical and horizontal loads, but in most applications tilt movements around any horizontal Allow axes.
  • These tilting joints are used in particular in bridge construction to support the superstructure on a support bench.
  • the deformable pressure mass is a plastic mass which is enclosed on all sides by the bearing pot and the cover.
  • the lid is supported in the vertical direction on the deformable pressure mass and in the horizontal direction on the pot wall.
  • the wall of the pot is stressed both by the side pressure of the pressure mass and by the external horizontal forces exerted on the cover. This horizontal stress causes large wall thicknesses of the pot wall and in the area of the connection to the pot bottom.
  • a central horizontal bearing takes over all horizontal forces that occur.
  • the lid of the storage pot is symmetrical to the bottom of the pot.
  • a circumferential seal is arranged in the area of the pot wall, but does not transmit any horizontal forces.
  • a second, circumferential seal surrounds the central horizontal bearing and seals it against the pressure mass contained in the annular bearing cup. The vertical load is thus only transferred into the annular space filled with pressure mass and surrounding the horizontal bearing, the outer diameter of which must be chosen to be correspondingly large.
  • the object of the invention is therefore to design a tilting bearing of the type mentioned in the introduction in such a way that it can be designed with the smallest possible external dimensions.
  • This object is achieved in that the existing space between the end face of the journal and the bottom of the bearing recess is filled with pressure mass and connected via a channel to the interior of the bearing pot.
  • the entire bearing pot forms a single, coherent pressure chamber, a seal to the central horizontal bearing being dispensed with.
  • the entire inner surface of the bearing cup including the surface above the journal is available as a pressure-transmitting bearing surface for transmitting the vertical load. This is particularly advantageous when large horizontal forces have to be transmitted and the diameter of the journal is therefore large.
  • the enlargement of the dimensions of the central horizontal bearing does not necessitate an enlargement of the external dimensions, because the entire area of the horizontal bearing is also used to transmit the vertical forces.
  • the thickness of the pot bottom can increase from the pot wall to the central horizontal bearing in order to introduce the horizontal forces from the horizontal bearing into the pot bottom, without however necessitating an increase in the external dimensions of the tilting bearing.
  • the journal of the horizontal bearing is attached to the bottom of the pot and engages in a bearing recess in the cover. This results in a particularly simple construction and inexpensive manufacture.
  • the bearing journal is attached to the cover and engages in a corresponding bearing recess in the base of the pot.
  • the tilting bearing can be filled with a pressure fluid as a pressure mass through a closable connection opening in the pot wall or in the lid.
  • the bearing journal is rotationally symmetrical and the bearing recess is a central bearing bore. If, on the other hand, a tilting movement is required only about a single horizontal tilting axis, then the bearing journal according to the invention is a bar which extends essentially over the width of the bearing cup and the bearing recess is a bearing groove in which this bar engages.
  • the bearing journal has proven to be particularly advantageous, in a further development of the inventive concept, to provide the bearing journal with a spherical, preferably spherical outer surface which is supported horizontally on a cylindrical bore wall of the bearing bore. Since practically no vertical displacements can occur due to the incompressibility of the deformable pressure mass, the bearing journal is stressed by Hertzian compressive stresses in the area of contact with the cylindrical bore wall of the bearing bore.
  • the cup seal lies in a groove and is self-sealing due to the lip on the cup wall.
  • the tilting bearing has a bearing cup 4, which rests on a compensation layer 5 on the support bench 3.
  • the storage pot 4 has a pot base 6, from the peripheral edge of which a cylindrical pot wall 7 projects upwards.
  • the storage pot 4 is closed by a cover 8 which supports the bridge superstructure 2.
  • An incompressible deformable pressure mass 9 is enclosed between the cover 8 and the bearing pot 4 in an interior space 4a that is closed on all sides, which can be a liquid or a plastic compound that subsequently cures to form a readily deformable compound.
  • a cup seal 10 is arranged between the circumference of the cover 8 and the cup wall 7. The pot seal 10 allows the vertical displacements that occur when the bridge superstructure 2 is tilted relative to the support bench 3 between the cover 8 and the pot wall 7.
  • the cup seal 10 has a sealing ring 10a inserted in a circumferential groove 11 of the cover 8. The sealing ring 10a lies firmly against the pot wall 7 with its sealing lip 10b.
  • the surface area of the sealing ring 10a or the sealing lip 10b which is acted upon by the internal pot pressure is so large in comparison with the area exposed to the external pressure that the sealing ring 10a forms a self-sealing cup seal, that is to say the contact pressure of the sealing lip 10b on the inner surface of the cup wall 7 and thus the sealing effect also increases with increasing internal pressure of the pressure compound 9.
  • a horizontal bearing 12 is arranged, which transfers the horizontal forces between the cover 8 and the bearing pot 4.
  • the horizontal bearing 12 has a centrally mounted on the pot base 6, upwardly projecting journal 13 which engages in a central bearing bore 14 in the cover 8.
  • the bearing pin 13 is provided on its circumference with a spherical outer surface 15, which is a spherical surface in the illustrated embodiment and is on a cylindrical. Bore wall 16 of the bearing bore 14 is supported horizontally.
  • the top 17 of the pot base 6 forms a flat truncated cone.
  • the thickness of the pot base 6 increases from the pot wall 7 to the central horizontal bearing 12. Of the Pot bottom 6 thus has its greatest thickness in the middle, where the horizontal forces are introduced by the journal 13. In addition to the sealing forces of the pot seal 10, only the horizontal forces from the side pressure of the pressure compound 9 act on the pot wall 7, but no horizontal forces transmitted by the cover 8.
  • an intermediate space 18 is provided, which is connected via a channel 19 to the interior 4a of the bearing cup 4.
  • a pressure equalization between the interior 4a and the intermediate space 18 takes place through the channel 19, so that the cover 8 is acted upon by the pressure of the pressure medium 9 over its entire base area.
  • the pot wall 7 has a closable connection 20 through which the pressure compound 9 can be fed into the storage pot 4.
  • the embodiment shown in Fig. 2 differs from the exemplary embodiment in Fig. 1 primarily in that the journal 13 of the horizontal bearing 12 is attached to the lid 8 and engages in a bearing recess 14 in the middle of the pot base 6.
  • the channel 19, which connects the intermediate space 18 between the bearing journal 13 and the bearing recess 14 with the surrounding interior 4a, is designed as an oblique bore. Several such bores can be provided.
  • connection 20 in the pot wall 7 or alternatively to this connection 20 also indicates that in addition to the connection 20 in the pot wall 7 or alternatively to this connection 20, a connection 20 'is provided in the cover 8. Through the connection 20 ', the pressure mass at Assembly of the tilting bearing can be injected.
  • all essentially the same components in the embodiments according to FIGS. 1 and 2 are designated by the same reference numerals.
  • FIGS. 3 and 4 differs from the embodiment of FIG. 2 essentially in that the pot wall 7, the bearing pin 13 and the side wall of the bearing recess 14 have such a high height that the cover 8 by supplying pressure mass 9 can be raised vertically by a lateral height 20 from the position shown in FIG. 3 to the position shown in FIG. 4 by the lateral connection 20, the spherical outer surface of the bearing journal 13 engaging with the side wall of the bearing recess 14 over the entire stroke remains. Likewise, the seal 10 remains in sealing engagement with the pot wall 7 during the entire stroke.
  • the tilting bearing 1 is also suitable for a height adjustment, as may be necessary in bridge construction, for example in subsoil subsidence.
  • the lid 8 is raised by supplying pressure mass.
  • an initially set bearing height can also be reduced by releasing pressure mass through the connection 20.
  • the pressure mass in the storage pot 4 is no longer liquid, it can be liquefied again by briefly heating the bearing.
  • a suitable pressure mass is selected which becomes fluid when heated.
  • All-sided tilting bearings have been described as exemplary embodiments, which allow tilting movements in all directions because the bearing journal 13 is rotationally symmetrical is. This results in particularly favorable stresses for the pot base 6. If, on the other hand, a tilting option is required only about a single horizontal tilt axis, the bearing journal 13 is designed as a horizontal bar which extends over the width of the bearing cup 4 and engages in a bearing groove forming the bearing recess. Such a one-sided tilt bearing looks in vertical section, for example, just like the all-sided tilt bearings shown in the drawing.
