Problems solved by technology

[0007] This disadvantageously leads to tensile stresses in the elastomer material, due to which separation of the elastomer material from the component occurs at contact surfaces adjacent to surrounding components
This weakens the mechanical connection and also reduces the shock absorption capacity

Embodiment Construction

[0038] exist figure 1 In the radial section of , the bearing arrangement 1 can be seen, with which the support roller 10 , which is only partially shown, is supported relative to the shaft part 14 .

[0039] Bearings 9 in the form of deep groove ball bearings are used for this purpose. The inner ring 15 of the bearing is fixed on the shaft member 14 . The outer ring 11 is arranged in an intermediate carrier 12 which itself is located above the unit consisting of the first sleeve part 2 and the second sleeve part 3 with the ring 4 of elastomeric material arranged therebetween.

[0040] The first sleeve element 2 is fixedly connected to the support roller 10 , while the second sleeve element 3 is connected to the intermediate support 12 . Accordingly, a damping mounting of the support roller 10 relative to the shaft part 14 is formed by the ring 4 made of elastomer material, corresponding to constructions known per se.

[0041] A unit consisting of a first sleeve part 2 and a...

Abstract

The invention relates to a method for manufacturing a bearing device (1). The bearing device comprises at least one first sleeve piece (2) and a second sleeve piece (3) which is concentric with the first sleeve piece (2), wherein a ring (4) made of an elastomer material or a rubber material is arranged between the two sleeve pieces (2 and 3). The method is characterized by comprising the following steps of: a) positioning the first sleeve piece (2) in a die casting mould (5), wherein the die casting mould (5) is provided with a cylindrical groove (6) which is used for accommodating the first sleeve piece (2) and has the diameter (D0); b) concentrically positioning the second sleeve piece (3) and the first sleeve piece (2) in the die casting mould (5); c) injecting the elastomer material or the rubber material in a melt state into an annular space (7) between the two sleeve pieces (2 and 3) under pressure (p) so as to expand the external diameter (Da) of the first sleeve piece (2); d) solidifying the elastomer material or the rubber material in the annular space (7) between the two sleeve pieces (2 and 3); and e) removing a unit consisting of the two sleeve pieces (2 and 3) and the ring (4) made of the elastomer material or the rubber material from the die casting mould (5). In addition, the invention relates to the bearing device.

Description

technical field [0001] The invention relates to a method for producing a bearing arrangement comprising at least one first sleeve part and a second sleeve part arranged concentrically with the first sleeve part, wherein between the two sleeve parts A ring made of elastomeric or rubber material is provided. The invention also relates to a bearing arrangement. Background technique [0002] Various possibilities are known in the prior art, including special designs, for the purpose of improving vibration damping, a layer of damping material is provided between the outer shell of the backing roll and the bearing, which is usually designed as a rolling bearing, for supporting the backing rolls . [0003] Such a bearing arrangement is known from DE 1 738 837U. An elastomer damping layer is used here, which is block-shaped in radial section and has constrictions in its two axial end regions. With such a damping layer, a high damping capacity of the bearing arrangement can be ac...
