Definitions
- the invention relates to a bearing assembly for an at least partially hollow cylindrical roller bearing, with at least one bearing roller bearing stock, between a ring of the bearing and the support roller directly or indirectly a damping layer of elastomeric or rubber material is arranged and wherein at least one axial end of the support roller closed by a lid.
- the invention is therefore based on the invention based on a bearing arrangement of the type mentioned in such a way that it is possible to ensure a vibration-damping attachment of the lid in a simple manner, this is to be possible in manufacturing and assembly technology simple manner.
- the dishevel should be arranged self-centering in its receptacle.
- the solution to this problem by the invention is characterized in that the lid is arranged in and held by a holding section, which is formed in an axial end region of the damping layer of the material of the damping layer.
- the cover has an axially extending annular portion which is arranged in the holding portion and held by this.
- the holding portion has a radially inwardly directed cylindrical seat.
- a radially inwardly directed projection may be arranged in the axial end region of the cylindrical seat. This can circulate annularly around the entire circumference of the holding portion.
- the damping layer preferably has a cover surface facing radially inwardly disposed within the holding portion.
- the contact surface advantageously has a surface normal pointing in the axial direction.
- An axially extending annular groove-shaped recess can be arranged between the holding section and the contact surface.
- the holding portion preferably extends axially to the axial position of a radially extending outer surface of the lid.
- At least one recess may be incorporated in the damping layer. This can rotate annularly around the entire circumference of the damping layer. But it is also possible that a number of recesses is arranged distributed over the circumference of the damping layer. In this case, webs can remain in the damping layer between the recesses. The webs can be arranged equidistantly around the circumference of the damping layer.
- the mounting of the lid is facilitated if it is provided that the axially extending annular portion of the lid has an insertion bevel.
- a sleeve-shaped body is arranged in at least one axial portion region of the support roller between the inner cylindrical surface of the support roller and the damping layer.
- the sleeve-shaped body can project beyond the carrying roller on one side axially and have a radially outwardly extending collar in the axial end region of the carrying roller.
- the damping layer is preferably formed as a thin-walled, hollow cylindrical element. Between the damping layer and the one ring of the bearing, a carrier body may be arranged.
- the sleeve-shaped body facing inner surface of the support roller and / or the support roller facing the outer surface of the sleeve-shaped body is provided with a coating with friction-enhancing property.
- This coating with a friction-increasing property preferably has diamonds, silicon carbide (SiC), corundum or boron nitride (CBN).
- the diamonds, the silicon carbide, the corundum or the boron nitride is usually present as a grain with a diameter range between 1 .mu.m and 100 .mu.m, preferably between 10 .mu.m and 80 .mu.m before.
- the diamonds, the silicon carbide, the corundum or the boron nitride can be bound according to a preferred embodiment of the invention with a binder on the support roller and / or on the sleeve-shaped body.
- the binder may be a metallic layer, in particular a nickel layer. This is preferably applied by a galvanic process.
- the friction enhancing coating may also be a molybdenum layer. This is preferably applied by flame spraying.
- Between the support roller and the sleeve-shaped body is preferably in the assembled state before a press fit.
- the radially outwardly extending collar and the support roller may be interconnected in the axial end region of the support roller.
- a preferred embodiment provides that this connection is made by an adhesive bond. This has advantages in terms of the tightness of the composite of the two components, which is particularly important because of capillary action between the two components. Furthermore, an adhesive bond has a positive effect with regard to the corrosion protection.
- Another solution provides that the radially outwardly extending collar and the support roller are welded together. In this case, a weld seam is preferably provided which is formed completely circumferentially around the circumference of the support roller. Also possible is a connection by friction. The type of connection is usually selected by the height and direction of the axial force.
- the support roller and the sleeve-shaped body may further be arranged at least one sealing element to protect the assembly against the ingress of dirt and moisture.
- the sealing element in this case is preferably an O-ring.
- the damping layer is preferably made of an elastomer or rubber material. Rubber material has proven particularly useful, in particular NBR with a Shore hardness of at least 40.
- the sleeve-shaped body and possibly the carrier body are usually made of metal, in particular of steel.
- the at least one bearing is preferably a rolling bearing.
- the support roller is preferably designed as a tube of constant wall thickness, which is mounted in both axial end regions, each with a bearing.
- the assembly of the lid can be done in a simple manner, resulting in a self-centering effect for the lid to the axis of rotation.
- the seal works effectively because there are both radial and axial sealing surfaces.
- the intended damping layer - preferably made of elastomer or rubber material - provides a roundness compensation and a vibration decoupling. Furthermore, this jerky loads are better intercepted.
- the sleeve-shaped body including damping layer, optionally carrier body and bearing together with seal 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. Another important advantage of the proposed solution when using the friction-increasing coating is that the axial attachment can be improved, whereby micro-movements can be prevented. This in turn reduces the formation of fretting corrosion.
- the highest torques can thereby be transmitted without the connection of the components being released. Furthermore, slippage of components is largely excluded. This is particularly advantageous when circulating bending occurs during operation of the support roller, which can not develop a negative effect due to the selected configuration of the bearing assembly.
- the proposed bearing arrangement is preferably used in surface mining and here is an essential part of a support roller device.
- microforming resulting from grain coating or molybdenum offers a completely new possibility for mounting rolls.
- a welding of components in the bore of the support roller shell is not required, but a high security against rotation is given. By eliminating welding, the welding distortion can be avoided, which can otherwise cause the risk of imbalance. Likewise, no welding coaxial errors can occur. As a result, no balancing of the mounted idler roller is required, ie no attachment of balancing elements. Despite the absence of welding, a creeping movement between the parts can be excluded.
- FIG. 1 shows the radial section through a bearing assembly with a support roller, which is supported by a bearing, wherein a the axial end final cover is not shown,
- Fig. 2 shows the upper, right end portion of the bearing assembly including carrying roller of FIG. 1 in an enlarged view, in which case the final cover is shown, and
- FIG. 3 shows the detail "Z" according to FIG. 1.
- a bearing assembly 1 which serves to support a support roller 2 of a conveyor. Shown is a shaft 25 on which a deep groove ball bearing 3 is fixed.
- the outer ring 4 of the deep groove ball bearing 3 carries a carrier body 18, which has a one-sided board, which surrounds the outer ring 4 axially and forms an axial abutment for him.
- the support roller 2 is formed as a hollow cylindrical component, ie as a tube, wherein a bearing assembly 1 is arranged in both axial end regions, as can be seen in Fig. 1.
- a sleeve-shaped body 16 is pressed, which sits with a press fit in the support roller 2.
- a damping layer 5 is arranged made of elastomer or rubber material, which is designed here as a hollow cylindrical layer.
- the elastomer or rubber material may be directly connected to the sleeve-shaped body 16 and / or to the carrier body 18 by an injection molding process or by a vulcanization process.
- the radial thickness d of the damping layer 5 is in a defined size range, which is determined in this case in relation to the outer diameter D of the support roller 2.
- the thickness d is preferably in a range between 1 and 10%, preferably between 1.5% and 4%, of the outer diameter D. This value ensures that, on the one hand, there is adequate damping of the carrying roller, but, on the other hand, one sufficiently precise and stiff guidance of the support roller is ensured.
- a radially outward - Shen extending collar 17 has.
- This collar 17 can also be addressed as a projection and forms a defined axial stop for the support roller 2.
- An axial fixation of the support roller 2 relative to the sleeve-shaped body 16 is thus possible in a simplified manner.
- the support roller 2 and the sleeve-shaped body 16 are firmly connected.
- a weld 24 extends between the axial end of the support roller 2 and the collar 17. This weld 24 runs over the entire circumference of the support roller 2 and the collar 17 to.
- a lid 6 outlined, which is inserted and fixed on the front side at the axial end of the bearing assembly and prevents the ingress of impurities.
- the cover 6 has an annular section 7 extending in the axial direction.
- This hollow cylindrical section 7 is arranged in the mounted state in a holding section 8 and is held by this.
- the holding portion 8 is formed in an axial end portion of the cushioning layer 5 of the material of the cushioning layer.
- the holding section 8 has a cylindrical seating surface 9 pointing radially inward for the annular section 7. Furthermore, am
- Holding portion 8 a radially inwardly projecting projection 10 is present, which rotates over the entire circumference of the holding portion 8.
- the damping layer 5 also has a contact surface 1 1, which is designed to abut the lid 6.
- This contact surface 11 has a surface normal, which points in the axial direction a.
- the transition between the abutment surface 11 and the cylindrical seat surface 9 is formed by a ringnutförmige recess 12, which can be referred to as undercut.
- the holding portion 8 extends axially as far as an outer surface 13 of the lid 6, so that in this respect results in a flush outer end surface.
- annular circumferential recess 14 is presently provided, which allows the holding section 8 to spring open radially when the lid 6 is inserted (from the right) during assembly, so that it comes to lie in the outlined position , The assembly process is facilitated by an insertion bevel 15, which is incorporated in the axial end region of the annular portion 7 of the cover 6.
- the recesses 14 may also extend only over short peripheral areas and, viewed in the axial direction, represent a star-shaped arrangement.
- the recess 14 is thus formed as an axially demolding cavity with or without intermediate webs.
- the elastomeric material of the holding portion 8 surrounds the annular portion 7 of the lid 6 by positive engagement with appropriate Ü berdeckung and thus guarantees a high degree of tightness.
- the projection 10, meanwhile, also biases the cover 6 axially after being pressed axially into the elastomer material, so that the end face of the cover 6 or, more precisely, the end face of its annular portion 7 bears against the contact surface 11 and thus also creates an axial seal ,
- FIG. 1 the detail "Z" is shown in FIG. 1, it being noted that this is a schematic representation, showing a coating 21 which has a friction-increasing effect and that between the inner surface 19 of the carrying roller 2 and the outer surface 20 of the sleeve-shaped body 16 is arranged.
- the grain diameter preferably moves in the range between 20 microns and 60 microns.
- the grains 22 are fixed with a binder 23 in the form of a galvanically applied nickel layer on a component - in the embodiment on the outer cylindrical surface of the sleeve-shaped body 16 - fixed.
- the coating in question is particularly advantageous in the front region of the sleeve-shaped body 16, since corrosion protection can also be achieved by the coating. There namely, it can easily come due to the capillary action between the components for the penetration of moisture. This can be counteracted particularly favorable if a manganese phosphating is provided as the coating. In particular, a chemical nickel plating has proven itself. This is available on the market, for example, under the name “Durni Coat.” The formation of fretting corrosion is thus effectively counteracted.
