Shock-absorbing roller or roller, especially for Roller tables and similar tracks

The innovation concerns a shock-absorbing roller or roller with a fixed axis or a rotating shaft, in particular for roller tables and similar tracks.

When angular transport goods run up on the rollers of a roller table or similar equipped with rollers or cylinders Conveyor it comes to hard knocks, which not only to Damage to the rollers can lead, but above all constantly cause very annoying loud noises.

In order to reduce the extent of this nuisance., For Roller tables used rollers whose axis is resiliently mounted and / or whose jacket is made of an elastic material or at least is covered with elastic material.

These measures reduce the impact and thus the noise but inadequately attenuated, so that the noise especially in Halls with several long walkways can become unacceptable for those working there.

The innovation is based on the task of designing a roller for roller tables and the like in the simplest possible way so that da.3 those exerted on the rollers by the transported goods

Stößo and thus the more surprising noise as far as possible be dampened.

To solve this problem, it is proposed according to the innovation, one taut at or near the two ends of the roll a radially divided, rotatably connectable to the roller shaft or enclosing the outer ring of a roller bearing To provide bushing seated damping ring made of elastic material, which is clamped secured by the two socket parts against axial displacement and its on and near . its periphery lying in a circular area Inner groove of the roll shell is.

This means that a roller table roller that is extremely economical to produce and can be set up on very simple wines is found, the noise dampening of which is considerably better than the known types. This is also still the case if - z. B. for transporting sharp-edged metal sheets and the like. - The metallic roller shell cannot be covered with an elastic plastic shell. The innovation also provides the additional advantage that they obliquely with means of their acting in the axial direction elasticity · "to the roller longitudinal axis of a flooding Good not only the on _T fahitetoß attenuates but also its inclined position automatically ■ slightly corrected. As a result of by the plurality of rollers If this correction is repeated multiple times, the material is pushed into the correct position.

The cross-section of the damping ring can be extremely different selected v / earth and z. B. square or round. It is preferably trapezoidal - similar to a V-belt profiled - cross section used. In order to increase the

radial and axial elasticity can also be an inward or with an open cross-section on the outside.

After the damping ring on one of the two socket parts is pulled up, these are firmly connected to each other. If a legible connection is desired, the two Socket parts preferably by means of parallel to the roller axis Screws connected.

The socket parts expediently consist of a thermoplastic material. They are preferably permanently connected to one another by gluing or friction welding. Purpose s easier and more precise assemblability, one of the two socket parts has a cylindrical or somewhat conical extension, onto which the other socket part dit a correr ·; · ■ end-to- end enlargement of its axial bore can be pushed on i: l.

Fig. 4 and 5 One role each advises a fixed axis. In the embodiment shown in FIG. 1, a socket composed of two parts 2 and 3 is seated on a V / elle 1. Both socket parts 2, 3 are made of a thermoplastic material. The part 2 has a somewhat conical extension 2 ', with which the conical enlargement 3' of the axial bore of the socket part 3 corresponds. Furthermore, there are two socket parts 2, 3 facing each other, spherical flutes 4, which when the two parts are joined together to form an annular groove with an approximately semicircular cross-section. Before these parts 2, 3 are pressed together, a damping ring 5 with a round cross-section that fits into this ITuL is inserted between.

In Fig. 2, cine is only a little; Modified design shown in which the two socket parts 2, 3 cylindrical mating surfaces 2 ', 3' oufweinen. The 5 required for the Dä ^ ipfungsring groove '■ [placed because of the four-edged DaTipfungsring-Quercchnittes for the greater part on the female part 2, the extension 3' has its axial bore. The pressure ring 8 here has an angled cross-section and is connected to the roller shell 6 by means of dowel pins 10.

Also in the embodiment according to FIG. 3, the seat is off The assembly made up of the triles 2, 3 and 5 is non-rotatable on a shaft 1 which can be rotated in a bearing, which is only indicated schematically. Those made of thermoplastic material Socket parts 2 and 3 are releasably connected to one another here by means of clamping screws. Part 3 is a steel one Ring washer 12 let in with a number of threaded bores corresponding to the screws 11, while one in the part 2 Recessed washer 13 forms a solid base for the screw heads 14-. Of course you can instead of the two Ring washers 12 and 13 also include nuts and washers. The damping ring 5 is here with a right-angled Cross section drawn; the pressure ring 8 is glued into a roller shell 6 made of thermoplastic material.

4 and 5 show exemplary embodiments in which the bushing parts 2 and 3, which are firmly connected to one another, also clamp the outer ring 15 of a roller bearing 16 between them, in addition to the damping ring 5 or 5 '. This assembly is drawn onto a journal 17 which has a milled recess 18 so that the loose roller blind can be hung in the holder of a roller table or the like. While a full trapezoidal damping ring cross-section is shown in FIG. ¹ Y, FIG

axial elasticity towards the socket is hollow. The outer bushing part 2 has a direction towards the roller axis 17 extending annular disk-shaped overhang 19 »means which the roller bearing 16 is shielded from contamination.

Of course, the cross-sectional shape of the damping ring 5, 5 ¹ or the grooves, the type of connection of the socket parts 2 and 5 and the shape and type of fastening of the pressure ring can be selected very largely independently of one another.
