"Center-free pivot-less roller pivot connection"

1.

The invention "refers to mid-free _s ,, are drehzapfenlos supported roller pivot connections with one or more roller sets are provided, wherein the axes of the rollers are respectively disposed in the roller and cage radially or in parallel or in an inclined angle to the Drehverbindungsaoh.se. The treads of the rollers per Depending on the material selected, either unhardened or hardened or hardened and ground or polished or, in the case of a suitable non-hardened material, by steel bandages - which can also be hardened or tempered - or protected against wear by similarly hard materials. The rollers can be cylindrical or have conical l ^ orm .--

The rollers are - if necessary -. In cages, which are designed ring-shaped or segment-like manner with any subdivision ... ^ or by individual spacers between the individual rollers performed so ₅ that the individual role in clamp-like design and accordingly der.üfigform he design of the individual intermediate piece - is guided radially * so that a perfect unwinding of each individual roll is guaranteed »The cages can be made from various modern materials, - primarily in non-cutting deformation»

The forces acting in the roller axis can be achieved using suitable hard materials, such as those listed above Steel bandages or steel wires to prevent premature wear of the roller swivel joint body will, . .

By arranging several roller and cage assemblies in the slewing ring with radial axes and - parallel axes of the rollers "or the axles at an inclined angle to the rotating connection axis, the center-free, pivot-free roller slewing rings can absorb loads in all directions of force, such as radial forces and axial forces and moments of force ₅ .

Kitten Free, trunnion loosely Brehverbindungen are ₅ to replace -verschiedenen versions known to all sides famous royal chair in a simple form * You will be primarily as Eugeldrehverbindungen, after-as roll bearing Led ο None of the known types, but shows the described in the invention benefits _s to sämtliche.auftretenden To be able to absorb forces and moments of force.

The accompanying drawing explains the invention?

Fig. 1 shows as a sectional drawing an arrangement of several -. ' -. Roller rings- in a center-free, pivot-less roller slewing ring j as they can be used according to the invention. Here, a roller ring is shown at the top and bottom, each with a roller ring - mmt- radially to the rotating joint axis - ] rollers mounted to the rotary joint axis.

Fig. 2 shows one of the possible embodiments of a joint of a steel bandage used in the invention ...

Fig. -3 - shows an arrangement of two roles in a cage with one of the possible forms of spacing of the individual roles from each other, here a care-taker-like design. ■. -;

to Figo 1? . The roller slewing ring consists of here. three Brehrings 1, 2 and $, which are designed in a functional, profiled form _? that they roll wreaths - in.

this 3PaIIe 3 - can take on, these are the ones Shoulders 4, 5 and 6, the ones that are suitable here Steel drums 7, 8, 9, IQj- 11 and 12 · are running.

The forces acting in the respective axes of the rollers can be controlled by steel bandages or, like "liier "shown at rollers 4 and 5, can be caught by steel wires 13 and 14. The same can - if necessary on the rotating rings 1 and 2 on the corresponding Places for the roles β are provided.

As already mentioned in the description of the invention, can they with steel bandages or with Steel wires reinforced! Surfaces are also protected against premature wear of the rotary joint body by hardening - possibly by grinding or polishing - when using modern materials.

zu Pxgo 2% As an example, one of the steel bandages ¹ J ₉ 3y 9, 10, 11 and '- 12 listed in the IrfindungsbeSchbeschreibung is shown at its joint, which ensures a smooth transition of the roller body, because here the air gap in the joint of the steel bandages is kept low.

zu F ig, 3s Here two rollers 4 are shown, which in one of the cage shapes mentioned in the description of the invention - here designed like a bracket - are guided so that a practically perfect unwinding of the individual roles is guaranteed, whereby the appropriate design of the Intermediate form -. surfaces - here clamp surfaces running radially to the rotary joint axis between two rollers, the radial guidance of the axes of the individual rollers is practically guaranteed at the same time (15, 16) "
