Problems solved by technology

[0004] The disadvantage of the previously known solutions is that, first of all, when the support rollers are long, especially from a load-bearing roller length of more than about 1 meter, vibrations and thus increased noise occur due to rotor dynamics, which makes the support rollers the operation goes bad

Embodiment Construction

[0023] exist figure 1 A support roller arrangement 1 can be seen in the figure, which comprises a support roller 2 for supporting a conveying element of a conveying device (for example a conveyor belt). Shown is a shaft 14 which supports an inner ring 15 of the bearing 3 or 4 in the form of a deep groove ball bearing, the shaft 14 itself being fixedly arranged.

[0024] The outer ring 16 of the bearing 3 or 4 bears a support body 17 which has a one-sided edge which engages axially on the outer ring 17 and forms an axial stop for this outer ring.

[0025] The support roller 2 is designed as a hollow cylindrical component, that is to say as a tube, wherein a bearing 3 , 4 is arranged in each case at the two axial end regions, wherein the two bearings 3 , 4 have an axial distance a from one another. A sleeve-shaped body 18 is pressed into the inwardly facing surface of the support roller 2 , which is seated in the support roller 2 with an interference fit. Between the sleeve-sh...

Abstract

The invention relates to a support roller device (1) which comprises a support roller (2), wherein at least one part of the support roller (2) is designed to be hollow cylindrical, the support roller is supported by two bearings (3 and 4), and a mutual axial distance (a) is arranged between the two bearings. In order to stably run the support roller device, the support roller (2) is internally provided with at least one of damping components (5) within the axial extension between the two bearings (3 and 4), and each component is provided with at least one of rings (6) which leastways enclose a part of the periphery of the support roller (2) and are made from the damping materials.

Description

technical field [0001] The invention relates to a backing roll arrangement comprising an at least partially hollow cylindrical backing roll supported by two bearings which are arranged at an axial distance from one another. Background technique [0002] With regard to the support of the backup rollers, various possibilities are known in the prior art, which also include special embodiments in which, for the purpose of improving vibration damping, a layer of damping material is arranged between the backup roller and the bearing, which is generally designed as a rolling bearing . [0003] DE 1 738 837 U discloses a support device for support rolls. In this case, an elastomeric damping layer is used which is block-shaped in radial cross-section and has constrictions in its two axial end regions. With such a damping layer, a high damping capacity of the support device can be achieved. [0004] The disadvantage of the previously known solutions is that, first of all, when the ...
