Definitions

  • the invention relates to a bearing arrangement for an at least partially hollow cylindrical support roller, with at least one bearing roller shell bearing bearing, between a ring of the bearing and the support roller shell directly or indirectly a damping layer is arranged and wherein in at least one axial portion of the support roller shell between the inner cylindrical surface of the supporting roller shell and the Dämpf ⁇ ings slaughter a sleeve-shaped body is arranged.
  • BEST ⁇ TICUNQSKOPIE DE 28 01 879 A1 shows a further similar bearing arrangement, wherein the bearing carries a sleeve via an elastomeric intermediate layer.
  • the sleeve widened radially in an axial end region and is welded with its radially outer region on the cylindrical inner surface of the supporting roller shell.
  • the constriction of the damping layer is usually due to the fact that the material of the damping layer has a relatively high volume shrinkage after it has been injection-molded or scorched onto the surrounding components. After injection molding elastomer material, its volume may shrink by a few percentage points, for example up to 4.5%, so that corresponding contractions are produced.
  • the invention is based on the A u fg abe on, a bearing assembly of the type mentioned in such a way that ensures that even with the volume shrinkage of the material of the damping layer no material separation of surrounding components of the damping layer takes place, so that the function of the damping layer in full preserved.
  • the object of this invention is characterized in that the sleeve-shaped body has at least in the region of the axial extent of the damping layer a number of recesses extending radially through the sleeve-shaped body.
  • material of the damping layer possibly also only temporarily during the production of the component and until the material has hardened, can penetrate into these recesses.
  • the recesses can - seen in the radial direction - have a round shape.
  • a preferred alternative for this provides that the recesses in the radial direction have an elongated shape.
  • the surface of the recesses is according to a development - seen in the radial direction - between 25% and 60% of the entire surface of the sleeve-shaped body. A particularly preferred ratio is between 33% and 50%. Thereafter, the sum of the surface kept free by the recesses is the stated value, based on the entire surface of the sleeve-shaped body.
  • the damping layer may consist of elastomeric material, in particular of polyurethane. It can also consist of rubber material, in particular of nitrile rubber (NBR). This preferably has a Shore hardness of at least 40.
  • a bonding agent is preferably arranged before the damping layer is produced.
  • a carrier body can be arranged between the one ring of the bearing and the damping layer.
  • the sleeve-shaped body and / or the carrier body may be made of metal.
  • the sleeve-shaped body may consist of iron or steel sheet.
  • the damping layer is preferably introduced between the one ring of the bearing or the carrier body and the sleeve-shaped body by an injection molding process.
  • the sleeve-shaped body may protrude axially over the support roller shell on one side and have a radially outwardly extending collar in the axial end region of the support roller shell. It can be arranged with a press fit in the hollow cylindrical section of the carrying roller shell.
  • the carrier body may have a board, which engages over the ring of the bearing axially.
  • the bearing is preferably a roller bearing.
  • the support roller shell is preferably designed as a tube of constant wall thickness, which is mounted in both axial end regions, each with a bearing.
  • the damping layer is preferably designed as a thin-walled, hollow cylindrical element.
  • the radial thickness of the damping layer is at most 10% of the outer diameter of the supporting roller shell.
  • the radial thickness of the damping layer should be at least 1% of the outer diameter of the support roller shell.
  • the proposal according to the invention ensures that a specific ratio of bonded and non-bonded surface regions is given in the edge surface of the material of the damping layer.
  • an (Ober) surface area is created, which represents an unbound surface, which is available for volume compensation to this extent.
  • the material of the damping layer can enter into the recesses during the injection molding process and in the case of the volume contraction of the material from the recesses, partially return to the base body of the damping layer.
  • the above-mentioned area ratios take the preferred account.
  • the intended damping layer which is usually produced by an injection molding process, ensures a high degree of coaxiality of the components and for a vibration isolation. Furthermore, this jerky loads are better intercepted. It thus comes to a Acidzentritations free.
  • the sleeve-shaped body including damping layer, optionally carrier body and bearing can be designed as a unit, which is installed as such on the conveyor to which the carrier role belongs. This has logistical advantages. The assembly can be done by simply pressing the sleeve-shaped body in the support roller shell.

  • the outer ring 4 of the deep groove ball bearing 3 carries a support body 8, which has a one-sided board 10, which surrounds the outer ring 4 axially and forms an axial abutment for him.
  • Otherwise arranged in grooves snap rings 13, 14 and 15 are provided with which the bearing 3 relative to the shaft 11 and the bearing 3 relative to the carrier body 8 can be axially fixed.
  • the support roller shell 2 is formed as a hollow cylindrical component, ie as a tube, wherein in both axial end portions of a bearing assembly 1 is arranged, as can be seen in Fig. 1.

  • the recesses 7 pass through the sleeve-shaped body 6 completely, as is apparent from Fig. 2. This results due to the nature or elasticity of the material of the damping layer 5, that the material can at least partially enter the recesses 7. 2, a "meniscus" 12 is sketched, which indicates that, depending on the stress conditions in the material of the damping layer, material more or less strongly enters the recesses 7.
