Guided tour

The invention relates to a roller guide for a linear guide system, in particular with extremely long stroke paths from a hardened guide rail on which at least three rollers of each guide block run, which with the is firmly connected to the leading part, e.g. screwed, welded or similar.

There are roller guides on the market in which each guide block has three rollers which interact with a guide bar. The disadvantage of these guides, however, is that roller block and guide rail for each individual case have been specially designed and developed with the result that the market demand for compact construction is more diverse Fastening and installation options as well as a wide range of diameters for the rollers and more variable Arrangement of the load-bearing idlers has not yet been taken into account.

The present invention is therefore based on the object to avoid the disadvantages of the known constructions and a Possibility to create:, this guide rail prj.nzip, consisting from standard elements, roller guide block and standard leashes, to open up a new, broad field of application.

The solution of the problem consists in that arranged in each two guide block lying in the same Ebere rolls with egg ^"r" eitig mounted and mutually parallel axes ir. Distance from one another,

that one more role with one perpendicular to both of the other Axes standing axis is present and that at least one of the three axes is in an eccentric Bushing lies and the other axes are each in a concentric bushing.

Advantageously, all axes of a roller block have the same journal diameter and all bushings have the same external | diameter. I.

The advantage of the roller guide according to the invention exists above all in the fact that the guide can be set very precisely, which is especially important when too long leading parts several roller blocks must be used. In addition, the guide is very low-friction excellent and has no stick-slip effect when starting up « 'Furthermore, the guide according to the invention is relatively insensitive against contamination, because the hardened guide rails do not have to harden with lubrication. Through the further j Training results in the advantage that the load-bearing j rollers (with concentric bushing) are always in the load-bearing j Axis can be installed. With this new roller guide j, especially long stroke paths can be completely unproblematic. to realize it automatically. f

In the drawings, an exemplary embodiment is shown in FIG Invention shown, namely shows:

Figure 1 is a side view of a roller guide block with a cut Guide rail,

Figure 2 is a view in partial section.

According to FIGS. 1 and 2, the roller guide block 11 consists of two fastening faces 12 and 13 which are at right angles to one another and in which bores Ik are arranged. The fastening flanges 12 and I3 are supplemented by angles I5 and 16. In the wall 16, the axes 17 and 18 for the guide rollers 19 and 20 are screwed with nuts 21 at a distance from one another. The axes 17 and 18 are parallel to each other so that the two guide rollers 19 and 20 are in the same plane. The distance (A) of the rollers I9 and 2o corresponds to the thickness of the guide rail The axis 17 is mounted in a concentric bush 23,

whereas the bushing 24 for the axis 18 is eccentric * forms is, so with this axis 18 the distance A between ' the two guide rollers 19 and 2o is adjustable.

According to FIG. 1, a further guide roller 26 is arranged outside the wall 16 in another wall 25, the axis 27 of which is perpendicular to the axes 17 and 18. The roller 26 is at such a height that it rests against the side wall 28 of the guide rail ZZ , or in other words, the roller 26 is at the level of the space A. The axis 27 of this roller 26 is also with a concentric bushing in the wall 25 stored.

To use this roller guide, a guide bar 22 with the intended length, e.g. 2 m, is placed on the bearing block of a Device screwed tight. The guide bar consists of a hardenable steel and is made according to the requirements the continuous machining accuracy and the loads as well as the accuracy either hardened or e.g. inductive surface hardened.

Depending on the weight and accuracy of the parts to be guided 1

are two or more roller guide blocks 11 either |

with the surface 12 or the mounting flange 13 on the to |

the moving part and the part to be guided are screwed on, whereby the 1

pre-machined screw holes 14 can be standardized. At- §

1 to close the guide blocks 11 provided with the part \ is placed on the guide bar ZZ so that the two rollers 19 and 2o are on both sides of the guide rail 22 and abuts the roller 26 on the side wall 28th To adjust the play of the rollers 19 and 2o on the guide bar ZZ , the eccentric bushing 24 for the axis 18 of the roller 2o is rotated until the distance A between the two rollers 19 and 2o corresponds to the thickness of the guide bar 22. If several roller blocks 11 are required on one side, for example because of the weight of the part to be guided, it is advisable to use the concentric 3shaft for the axis 27 against an eccentric one

Replacing the socket, which is very easy because all the sockets have the same outer diameter. With the eccentric Bushing can then align all guide blocks 11 on one side of the guide rail 22 that all Rollers 26 rest evenly on the side of the wall 28 of the guide strip 22.

But it is also easily possible to have both axes 17 and 18 of the rollers I9 and 2o each with an eccentric socket in the guide bracket 11 to be attached so that several guide blocks 11 can then be precisely aligned on the guide bar 22, so that each guide block 11 is evenly loaded.

It is also possible to make the guide rail 22 wider and then to arrange roller guide blocks 11 on both sides. In this case, too, it may be desirable to align all rollers 19, 20 and 26 with an eccentric bushing 24 in order to ensure the greatest possible accuracy of the guide.
