Definitions
- the invention relates to a linear sliding bearing comprising an elongated rail and a slide with a complementary linear guide which interacts with the rail, the rail being designed as a one-piece double rail with two parallel rail elements and the linear guide of the slide having two parallel linear guide elements.
- Such a linear plain bearing can be used for the sliding guidance of a working device.
- a work device can have a wide variety of properties, for example it can be an element of a machine tool.
- the invention relates, for example, to a linear plain bearing that can be used in vehicle construction, especially in a commercial vehicle such as a tractor or a cleaning vehicle.
- the linear plain bearing is usually permanently installed in the vehicle.
- the rail of the linear plain bearing is attached to a vehicle part, whereas the working device can be detachably attached to the carriage.
- corresponding fastening devices are provided on the carriage and/or the working device.
- a person skilled in the art knows a generic linear plain bearing, which is designed as a one-piece double rail, from DE 20 2021 105 329 Ul.
- the known linear plain bearing has an actuating arm on one of the two linear guide elements, which is arranged transversely to the longitudinal extent of the rail and is displaceable in this transverse direction.
- the actuation arm can be fixed and detached in the transverse direction.
- a spring element can be provided, which cooperates with the actuating arm and biases it in the transverse direction against one of the rail elements.
- a general state of the art is from DE 20 2004 016 094 Ul known, which includes an example of a linear plain bearing with a double rail that is not made in one piece but is composed of individual rails. To do this, the individual rails must be screwed to a so-called base.
- the freedom or lack of play in the sliding guide of the linear plain bearing goes hand in hand with the screw mounting of the individual rails on the base.
- the parallel distance between the individual rails can be adjusted during the screw connection to the parallel distance of the linear guide elements, or parallelism or alignment errors of the rails that can occur during assembly and/or operation can be compensated for by means of the screw connection. This type of adjustment of the freedom or lack of backlash is perceived as being structurally complex and, moreover, the assembly effort appears to be too high.
- the invention is based on the object of proposing a structurally simplified linear plain bearing that can provide a desired freedom or lack of backlash and requires the least possible assembly effort.
- the object is achieved in that a first of the rail elements and a first of the linear guide elements form a guide unit, that a play-free or low-play sliding guide is provided by means of the guide unit, and that the second rail element forms a support guide with the second linear guide element.
- the support unit is designed to, to a certain extent, compensate for any dimensional deviations in the track width of the double rail and/or any deviations from ideal parallelism.
- the design therefore allows larger dimensional and shape tolerances, or larger dimensional and shape tolerance zones, to be permitted in the production of the double rail. This significantly reduces the effort and costs for producing the double rail.
- the design according to the invention also improves the interchangeability of double rails with different carriages. While according to the prior art, the track width of the double rail had to correspond well with the track width of the carriage, i.e. H . Both had to lie within a narrow tolerance zone, the tolerance zone can now be significantly increased.
- the rail element of the double rail which is provided with an outer contour, expediently forms a rail head.
- the one-piece rail is expediently manufactured using a primary forming or forming process that does not require any mechanical post-processing.
- a rail made of metal, in particular aluminum or an aluminum alloy, can be produced as an extruded rail profile.
- a double rail produced in this way has two rail elements, which are preferably designed symmetrically.
- the carriage on the other hand, is provided with the linear guide, which has two differently designed linear guide elements, namely the first linear guide element, with which the guide unit can always be created, and the second linear guide element, with which the support guide can always be created.
- the first linear guide element can optionally be combined with one or the other of the two rail elements. Inevitably, the management unit always arises. Likewise, the linear guide element can optionally be combined with one or the other of the two rail elements and the support guide is always created.
- the linear guide element provided with an inner contour advantageously has a C-shaped cross section with a side opening. The lateral opening is expediently dimensioned such that the inner contour of the linear guide element encompasses the rail element over a circumferential range of 180° to 320°.
- the intended play in the support guide is preferably a dimensional range of 0.05 mm to 1.00 mm, in particular 0.2 mm to 0.6 mm.
- slide bearing element provided on the side of the guide unit and the slide bearing element provided on the side of the support guide each conform to the cross section of the associated rail element.
- the sliding bearing element on the side of the guide unit also hugs the cross section of the linear guide element with its outer contour.
- the inner contour of the linear guide element expediently has a width that is greater than the width of the outer contour of the plain bearing element, so that a lateral play to the plain bearing element is formed. If the inner contour of the linear guide element has an oval cross section and the outer contour of the plain bearing element is cylindrical, then lateral crescent-shaped clearances are formed between the outer contour of the plain bearing element and the wide inner contour of the linear guide element. Parts of the outer contour of the plain bearing element then serve as a fastening side in order to partially bring the plain bearing element into contact with the inner contour of the linear guide element and fix it, while other portions of the outer contour of the plain bearing element each define one side of the crescent-shaped clearance.
- each of the two guide sections has a certain length and a certain distance is provided between the two guide sections. In this way, an overall favorable length of the guide can be provided. Otherwise, torque acting on the carriage could cause binding by tilting the carriage on the rail. Tilting would be facilitated by a guide that is too short.
- a suitable length ge of the guide section is in particular in the range of 0.1 to 1.5 times, in particular 0.2 to 1.0 times, the track width of the double rail.
- An appropriate distance between the guide sections arranged in a row is in particular in the range of 0.05 to 1.0 times, in particular 0.1 to 0.7 times, in particular 0.1 to 0.5 times the track width the double rail.
- linear guide elements are provided with two guide sections that lie one behind the other in a row and each guide section is expediently provided with a plain bearing element.
- the plain bearing elements provided in a row are at a distance from one another which is in the identical range of the expedient distance mentioned which is intended for the guide sections.

- FIG. 3 An enlarged detail according to I I I in Fig. 2
- Fig. 5 is a perspective view of the linear plain bearing according to FIG. 1
- Fig. 6 a front view of an alternative exemplary embodiment of a linear plain bearing according to the invention
- Fig. 7 A front view of the slide of the linear plain bearing according to Fig. 6,
- FIG. 9 A view according to IX in Fig. 8th .
- the linear plain bearing 1 according to the invention according to FIG. 1 a rail 2 and a carriage 3 with a complementary linear guide 4, which interacts with the rail 2.
- the rail 2 is designed as a one-piece double rail 5 with two parallel rail elements, a first rail element 6 and a second rail element 7, both of which are arranged in a common rail plane 8.
- the linear guide 4 of the carriage 3 has two parallel linear guide elements, a first linear guide element 9 and a second linear guide element 10, which are arranged to match the rail elements 6 and 7 of the double rail 5.
- the first rail element 6 of the double rail 5 forms a guide unit 11 together with the first linear guide element 9 of the carriage 3.
- the second rail element 7 forms a support guide 12 with the second linear guide element 10.
- the support guide 12 essentially enables the absorption of a load in a load direction L that runs orthogonally to the rail plane 8.
- the carrying guide does not have to fulfill a lateral guiding function.
- An enlarged detailed view of the support guide is shown in Fig. 4 illustrates.
- the rail elements 6 and 7 are designed as rail heads 6a and 7a, respectively. Both rail heads have a circular cross section, each of which forms a cylindrical outer contour 13 and 14, respectively.
- the rail head 6a is arranged with a web 15 on a base element 16 of the double rail 5 and the rail head 7a is arranged with a web 17 on the base element 16.
- the cylindrical outer contours 13/14 each serve as a sliding surface for the slide 2.
- plain bearing elements 18 and 19 made from plain bearing plastic are provided. These plain bearing elements are fixed in position with the linear guide elements 9 and 10 of the slide 2.
- the plain bearing element 18 is designed in the shape of a sleeve with a circular or annular cross-section. However, the annular cross-section is not closed, but is designed as a C-shaped open cross-section 20, so that a lateral opening 21 is formed. The web 15 of the double rail 5 fits through the side opening 21.
- the two plain bearing elements 18 and 19 are identical and can in principle be exchanged for one another.
- the plain bearing elements 18 and 19 are identical. However, the type of storage of the plain bearing element 19 in the linear guide element 10 differs from the storage of the plain bearing element 18 in the linear guide element 9. This is based on the Figs. 2 and 3 illustrate, each of which only represents the carriage, without a double rail.
- a sliding bearing element 18 and 19 is shown in both linear guide elements 9 and 10 of the slide.
- the linear guide element 9 has an inner contour 22 with a circular cross section 23 with a lateral small opening.
- the plain bearing element 18 is arranged concentrically to the inner contour 22 of the linear guide element 9.
- plain bearing element 18 according to FIG. 1 also arranged concentrically to the cylindrical outer contour 13 of the rail element 6.
- the linear guide element 9 encompasses/encompasses the rail element 6 indirectly, namely with the interposition of the plain bearing element 18. Viewed in cross-section, both include, i.e. H .
- the linear guide element 9 and the plain bearing element 18 both encompass the rail element in a circumferential area of approximately 290 °. This results in a positive connection between the linear guide element 9 and the rail element 6. Due to the form fit, the carriage cannot be removed from the rail either sideways or upwards. He only has one degree of freedom for his movement and that is in the direction of the longitudinal extension of the rail that guides him.
- the guide unit 11 is formed, which provides the play-free or low-play sliding guide function.
- “backlash-free” is understood to mean an almost backlash-free fit between the linear guide element and the rail element or a fit with a low elastic preload between sliding surfaces of the linear guide element and the rail element. With the latter measure, freedom of play can be guaranteed and it can be adjusted how smoothly or sluggishly the carriage can be moved in translation on the double rail.
- Low play is understood to be a sliding guide function that involves a guide play between the sliding surfaces of the linear guide elements and the rail element, which is a sufficiently small guide play, which can prevent jamming due to the carriage tilting on the rail when the torque acts on the carriage.
- the linear guide element 10 is provided with an inner contour 24 which has an oval cross section 25 with a side opening 26. It is best shown in Fig. 3 the oval cross section 25 with the side opening 26 can be seen, which is composed of two partial circle arcs 27 and 28 and a straight line 29. In this way, the support guide 12 is formed by means of the oval cross section 25.
- the oval cross section 25 as the inner contour of the linear guide element 10 has a width B that is larger than the outer diameter d of the plain bearing element 19. In this way, the outside/outer contour of the plain bearing element 19 has a lateral play 30 or 31 within the linear guide element 10.
- the size of the lateral play is measured by the length X of the straight line 29 of the oval cross section 25. Due to this design, the game 30 is designed as an almost crescent-shaped free space on the partial circle arc 27 and the game 31 is designed as an almost crescent-shaped free space on the partial circle arc 28. In Fig. 3, the plain bearing element 19 is located in the middle of the oval cross section 25. The crescent-shaped free spaces each offer a lateral play 30/31 of X/2, which corresponds to half the length of the straight line 29.
- the plain bearing element 19 has a central axis 19a and groove-shaped recesses 32a, 32b, 32c, 32d arranged in this axial direction are provided.
- the groove-shaped recesses can act as integrated dirt channels. Dirt particles can be stripped from the rail into a dirt channel and discharged via the dirt channel.
- the built-in play of the support guide is advantageously provided away from the inner contour of the plain bearing element.
- the inner contour of the plain bearing element can fulfill its purpose as a plain bearing surface better than known designs that have play arranged in the area of the inner contour of the plain bearing element.
- Fig. 4 shows a top view of the carriage 3.
- the linear guide element 9 of the carriage has two guide sections 33 and 34 arranged in series.
- the guide sections are aligned in a guide axis Fl.
- Each of the guide sections 33 and 34 is each provided with a sliding bearing element 18 or 18 ', which are identical to one another and interchangeable.
- the guide section 33 and the guide section 33 have a length K which essentially corresponds to the length of the plain bearing element 18.
- a distance M is provided between the two guide sections 33 and 34. The length K and the distance M are dimensioned so that jamming caused by tilting the carriage 3 on the rail 2 is counteracted.
- the linear guide element 10 has two support sections 35 and 36 arranged in series.
- the support sections are also arranged in alignment.
- Each of the support sections 35 and 36 is each provided with a sliding bearing element 19 or 19 ', which are identical to one another and interchangeable. They are also identical and interchangeable with the plain bearing elements 18 and 18 'of the guide sections 33 and 34.
- the plain bearing elements 18/18 ' are fixed in position with the Linear guide element 9 and the plain bearing elements are connected in a fixed position to the linear guide element 10.

- the linear guide elements each have an outer contour that matches the inner contour 44.
- the linear guide elements 45 and 46 of the carriage 41 are encompassed by the respective rail element 42 and 43, respectively. Viewed in cross section, the encompassing amount is also here a circumference of about 290 °.
- the positive connection means that the carriage 41 cannot be removed from the rail either sideways or upwards. It only has one degree of freedom for its movement, namely in the direction of the longitudinal extent of the double rail 40 that guides it.
- the linear guide element 45 has a cylindrical outer contour 47.
- a plain bearing element 48 which has a central axis, is arranged between the outer contour 47 and the inner sliding surface of the rail element 42.
- the plain bearing element 48 moves together with the carriage 41 during operation. For this purpose, it is connected in a fixed position to the outer contour 47 of the linear guide element 45.
- the plain bearing element 48 in turn has a cylindrical outer contour 49 which interacts with the internal sliding surface of the rail element 42 and slides thereon.
- the cylindrical outer contour 49 is provided in the axial direction with four groove-shaped recesses 50a-d, which extend parallel to the central axis and are open to the outside.
- the groove-shaped recesses 50a-d can act as dirt channels when the plain bearing element 48 is installed.
- the rail element 43 is arranged symmetrically to the rail element 42 but has an inner contour 43a with an oval cross section 43b.
- the oval cross section is wider than the hollow cylindrical inner contour 44 of the other rail element 42. Due to the greater width of the inner contour 43a, it offers a clearance S 1 or S2 for the linear guide element 46 or for the intermediate plain bearing element G.
