Description

The invention relates to a method for producing a linear guide device, which has a linearly movable on a longitudinal axis having a guide rail mounted guide carriage which has a slide body and at least one pair of guide units consisting of two guide rails on opposite longitudinal sides flanking and fixed to the carriage body guide units wherein the guide rail at its two longitudinal sides each having a rolling bearing surface arrangement and these two Wälzlagerflächenanordnungen in a direction perpendicular to the longitudinal axis of the guide rail transverse direction have a transverse distance to each other and wherein the guide units are biased with respect to the guide rail in the transverse direction, wherein rolling bearing elements each guide unit both on a rolling bearing surface arrangement of a guide body the relevant leadership unit as well as one of the two n Wälzlagerflächenanordnungen the guide rail play and rolling abradable.

A linear guide device produced in the aforementioned sense is known from EP 2 397 711 B1 known. The known linear guide device includes a guide rail, which is overlapped by a guide slide like a rider, so that the guide rail is flanked by two guide units. Each guide unit has a guide body and a plurality of roller bearing elements, wherein the rolling bearing elements between Wälzlagerflächenanordnungen the guide rail and the associated guide body are braced to realize a play-free guidance. The bias is achieved by a resilient clip that engages over the guide units and the guide rail. A rigid slide body, which has a U-profile, in turn engages over the clamp and is fixed in a form-fitting manner by securing wires to the clamp in order to complete the guide slide.

The known manufacturing method has, inter alia, the disadvantage that the bias acting between the guide units and the guide rail depends on the diameter of the spherical roller bearing elements here. The larger the ball diameter, the stronger the preload. To allow a smooth movement of the guide carriage, the bias should not be too strong. On the other hand, a certain bias is needed to keep the storage system backlash. In order to take these different requirements into account, it is essential in the known method to resort to individually presorted rolling bearing elements. This presorting and individual selection of the rolling bearing elements is very time consuming and has high manufacturing costs for the linear guide device result.

From the DE 38 24 192 C1 A method of the aforementioned type is also known, in which two guide units are screwed to a plate-shaped carriage body for producing a linear guide device, after previously by means of an eccentric a bias of rolling bearing elements has been adjusted, on the one hand to a guide body of the relevant guide unit and the other abut a guide rail engaging between the guide units. The adjustment of the bias takes place in sitting on the guide rail state of the two guide units and the carriage body having guide carriage.

From the DE 35 27 307 A1 It is known to adjust the position play between a guide carriage and a guide rail in that by means of an adjusting bolt, a biasing force is applied, which has an elastic bending of a plate-shaped carriage body result, are attached to the two guide units, which have applied to the guide rail rolling bearing elements.

The WO 95/25909 A1 describes the possibility of preventing the falling out of rolling bearing balls from a guide carriage removed from a guide rail in that the guide carriage is pushed onto an elastic ball support rail. To reinstall the guide slide can be moved directly from the ball rail on the guide rail.

The invention has for its object to provide a method for producing a linear guide device, which allows a cost-effective and fast way to produce a precisely working linear guide device.

• (a) Bereitstellung einer bezüglich der Führungsschiene gesonderten Montageschiene, die an einander entgegengesetzten Längsseiten jeweils über eine Montage-Wälzlagerflächenanordnung verfügt, wobei der Querabstand zwischen den beiden Montage-Wälzlagerflächenanordnungen kleiner ist als der Querabstand zwischen den Wälzlagerflächenanordnungen der Führungsschiene,
• (b) Anlegen der beiden Führungseinheiten jedes Führungseinheitenpaares an jeweils eine der beiden Montage-Wälzlagerflächenanordnungen der Montageschiene im noch nicht an dem Schlittenkörper befestigten Zustand der Führungseinheiten und Andrücken der Führungseinheiten an die Montageschiene, sodass die Wälzlagerelemente jeder Führungseinheit sowohl an der Wälzlagerflächenanordnung des Führungskörpers der Führungseinheit als auch an der zugeordneten Montage-Wälzlagerflächenanordnung der Montageschiene spielfrei anliegen,
• (c) Befestigen des Schlittenkörpers an den Führungseinheiten, sodass der Abstand zwischen den Führungseinheiten fixiert ist und der Schlittenkörper gemeinsam mit den Führungseinheiten den Führungsschlitten bildet,
• (d) Herunternehmen des Führungsschlittens von der Montageschiene,
• (e) Aufschieben des Führungsschlittens auf die Führungsschiene, wobei die Führungseinheiten aufgrund des im Vergleich zu den Montage-Wälzlagerflächenanordnungen größeren Querabstandes der Wälzlagerflächenanordnungen der Führungsschiene unter elastischem Verbiegen des Schlittenkörpers auseinandergedrückt werden und dadurch mit einer definierten Vorspannung mit der Führungsschiene verspannt sind.

To solve this problem, the production process is carried out with the following process steps:

• (a) providing a mounting rail separate from the guide rail, each having a mounting rolling bearing surface arrangement on opposite longitudinal sides, the transverse distance between the two mounting rolling bearing surface arrangements being smaller than the transverse distance between the rolling bearing surface arrangements of the guide rail,
• (B) applying the two guide units of each guide unit pair to each one of the two assembly-rolling bearing surface arrangements of the mounting rail in not yet on the Carriage body attached state of the guide units and pressing the guide units to the mounting rail, so that the rolling bearing elements of each guide unit rest against both the Wälzlagerflächenanordnung the guide body of the guide unit and the associated assembly Wälzlagerflächenanordnung the mounting rail clearance,
• (c) attaching the carriage body to the guide units such that the distance between the guide units is fixed and the carriage body forms the guide carriage together with the guide units,
• (d) removing the guide carriage from the mounting rail,
• (E) pushing the guide carriage on the guide rail, wherein the guide units are pressed apart due to the larger compared to the mounting roller bearing surface arrangements of the rolling bearing surface arrangements of the guide rail under elastic bending of the carriage body and are thus clamped with a defined bias to the guide rail.

The method according to the invention is based on the idea of assembling the guide carriages required for the production of linear guide devices on a separate mounting rail so that the guide units assume a predefined actual distance from one another which is slightly smaller than the nominal distance between these guide units present in the finished state of the linear guide device , From this difference in distance results in a bias between the guide carriage and the guide rail when the guide carriage is placed after the assembly on the mounting rail assembly on the associated guide rail. In other words, the guide rail is made so that the existing between their Wälzlagerflächenanordnungen distance is minimally greater than the existing between the mounting Wälzlagerflächenanordnungen the mounting rail distance. The difference in distance is preferably in the range of a few micrometers. The assembly of the guide rail on the markable as a master rail mounting rail is carried out such that the rolling bearing elements rest against each free play on a mounting roller bearing surface assembly and a rolling bearing surface of the associated guide unit, only to then attach the carriage body, which has the consequence that the guide carriage in itself is tension-free. Only when subsequently the guide carriage is pushed onto the actual guide rail, due to the width excess of the guide rail forms a certain bias, which ensures the necessary backlash of the system even during operation of the linear guide device, without causing the friction factor to rise excessively. The manufacturing method allows a reproducible production of linear guide devices, without a presorting or preselection of rolling bearing elements would be necessary. Regardless of differences in diameter of the rolling bearing elements used, a reproducible bias of the guide system can be achieved.

Advantageous developments of the invention will become apparent from the dependent claims.

In order to fasten the carriage body to the guide units in the pressed-on state of the mounting roller bearing surface arrangements of the guide units, at least one screw connection can be used per guide unit, which is effective between the carriage body and the guide body. For example, the carriage body can be screwed and braced with each guide body using one or more fastening screws.

Another possibility for fastening is the execution of a cohesive connection between the carriage body and the associated guide body. For example, an adhesive bond can be used here. Particularly advantageous is a welded connection is considered, which is particularly designed so that a weld in the region of the rolling bearing elements opposite back of a respective guide unit along the local joining region between the guide body and the carriage body is set.

It is possible to combine at least one screw with at least one cohesive connection. In this case, it is advantageous if the at least one screw connection is first produced with a type of prefixing in order subsequently to carry out the integral connection.

In particular, when using the above-mentioned welded connection, an additional screw has the advantage that the connection force is reinforced and in particular a firm cohesion between the guide body and the carriage body is ensured when the carriage body is exposed due to a corresponding application of the linear guide device high tilting forces.

Expediently, the transfer of the guide carriage assembled on the mounting rail to the actual guide rail takes place in a single operation, wherein the mounting rail and the guide rail are axially are arranged in alignment with each other and then the guide carriage is moved so that it is pushed axially during axial shutdown of the mounting rail on the aligned guide rail simultaneously. Such a procedure has advantages over a principle also possible approach, in which the guide carriage is removed after mounting on the mounting rail production of the mounting rail and stored individually to the combination with a guide rail.

However, even with an intermediate storage of the prefabricated guide carriage a simple and efficient production of the linear guide device is possible if the intermediate storage of the guide carriage in turn takes place on a rail adapted thereto, which can be referred to as a storage rail. The storage rail is in particular designed so that the guide carriage sitting thereon can be moved only in the longitudinal direction, as is the case with the mounting rail and with the guide rail, and is supported at right angles in all directions. However, it is preferable to form the storage rail such that, unlike the guide rail with respect to the mounting rail, it does not have an excess in width, so that the guide carriages stored thereon continue to be free of tension internally. Nevertheless, it is possible to choose the dimensions so that the stored guide carriage internally already subject to a certain bias.

The use of a storage rail has the advantage that one or more guide carriage can be stored as long as desired, with the exposed rolling bearing elements are protected. A assembly composed of a storage rail and at least one guide carriage seated thereon can be conveniently transported from the manufacturing site to a remote final assembly location, where only the transfer of the guide carriage or carriages to a provided guide rail is to be performed.

In the production of the linear guide device so there is the advantageous possibility, technically simple to produce guide rails geu tively at different final assembly available, which can then be combined as needed with sent to a central location and sent to the final assembly guide carriage. This has the advantage that costly manufacturing know-how can be cost effectively concentrated in one place.

The guide units are expediently designed so that their roller bearing elements are arranged in one or more circulation channels, wherein each circulation channel in conjunction with the rolling bearing elements therein defines a circulation rolling bearing unit. If the guide carriage is moved along the guide rail, the roller bearing elements travel along in the circulation channel and roll off at the same time on the opposite rolling bearing surface arrangements of the guide units and the guide rail.

As a slide body expediently a plate-shaped body is used. Preferably, the carriage body is a steel body.

From the 1 . 12 and 13 is in each case a linear guide device 1 which was produced in the context of a particularly advantageous embodiment of the production method according to the invention.

The linear guide device 1 has a linear guide rail 2 whose longitudinal axis dot-dashed at 3 is indicated. The guide rail 2 also has one to the longitudinal axis 3 right-angled transverse axis 4 and one to both the longitudinal axis 3 as well as the transverse axis 4 right-angled vertical axis 5 ,

The guide rail 2 has two in the axial direction of the transverse axis 4 oppositely oriented first and second longitudinal sides 6 . 7 , On each of these two long sides 6 . 7 is located in the axial direction of the longitudinal axis 3 extending rolling bearing surface arrangement 8th , The two Wälzlagerflächenanordnungen 8th lie in the axial direction of the vertical axis 5 expediently at the same height. In the axial direction of the transverse axis 4 are the two Wälzlagerflächenanordnungen 8th arranged with a transverse distance "A" to each other.

It may be at the guide rail 2 to act a one-piece body to which the rolling bearing surface arrangements 8th are integrally formed. Deviating from the illustrated embodiment, a preferred construction, in which the guide rail 2 via a one-piece rail body 12 has, on the independent bearing rails 13 are attached, each one of the rolling bearing surface arrangements mentioned 8th exhibit. The bearing rails 13 are suitably made of steel, which is preferably cured. The rail body 12 may for example consist of a light metal, in particular aluminum material.

Without further ado, the guide rail 2 Be part of a linear drive device. Such a linear drive device has, for example, a housing on which the guide rail 2 is arranged or that the guide rail 2 or their rail body 12 forms.

The linear guide device 1 also has at least one guide carriage 14 that is attached to the guide rail 2 in the axial direction of its longitudinal axis 3 is mounted linearly displaceable. The regarding the guide rail 2 possible linear movement 15 of the guide carriage 14 is illustrated by a double arrow. You could use the guide slide 14 Also call as a carriage. In one embodiment as a linear drive device contains the linear guide device 1 expediently drive means which on the guide carriage 14 attack, to its movement 15 to create.

The guide carriage 14 has one to the longitudinal axis 3 the guide rail 2 parallel longitudinal axis 17 , He also has one to the longitudinal axis 17 right-angled transverse axis 18 leading to the transverse axis 4 the guide rail 2 runs parallel. And finally, the guide sled 14 also one to the vertical axis 5 the guide rail 2 parallel vertical axis 16 ,

The guide carriage 14 is like that on the guide rail 2 mounted that same at a in 1 and 2 upward facing top 22 overlaps. The top 22 extends between the two long sides 6 . 7 ,

The guide carriage 14 has an at least substantially U-shaped configuration with two parallel leg portions 23 . 24 and a land portion extending therebetween 25 , The bridge section 25 extends over the top 22 away, while the two leg sections 23 . 24 starting from the web section 25 each project down and the guide rail 2 on both sides 6 . 7 flank. In other words, the guide rail 2 from the guide carriage 14 ridden like a rider.

The two leg sections 23 . 24 are each from one of two leadership units 26 . 27 of the guide carriage 14 educated. Every leadership unit 26 . 27 is at the guide rail 2 facing bottom 28 one of the bridge section 25 forming carriage body 32 of the guide carriage 14 arranged and fastened.

The carriage body 32 is expediently designed plate-shaped. Its plate plane is perpendicular to the vertical axis 16 ,

The carriage body 32 has two opposite, each in the axial direction of the transverse axis 18 oriented lateral edge sections 33 . 34 , These lateral edge sections 33 . 34 protrude in the transverse direction 18 over the guide rail 2 out and are on their underside, each with one of the guide units 26 . 27 Mistake.

The carriage body 32 is suitably made of steel.

A preferred construction of the guide units 26 . 27 goes out among other things 3 out. Accordingly, every leadership unit has 26 . 27 prefers a strip-shaped structure. In addition, each management unit has 26 . 27 via a one-part or multi-part guide body 35 that with a variety of moving rolling bearing elements 36 is equipped. Exemplary are the rolling bearing elements 36 spherically formed, but they could also be designed, for example, cylindrical.

The rolling bearing elements 36 belong to one or more in the leadership unit 26 . 27 integrated circulation rolling bearing units 37 , Exemplary is each leadership unit 26 . 27 with two such circulating rolling bearing units 37 but only one of them is illustrated in detail.

The circulation rolling bearing unit 37 contains one inside the guide body 35 trained, circular self-contained circulation channel 38 who in 3 indicated by dash-dotted lines. In this circulation channel 38 is a variety of rolling bearing elements 36 in a chain-like sequence. The rolling bearing elements 36 are able in the circulation channel 38 circulating, taking in the longitudinal direction of the circulation channel 38 hike.

The guide rail 2 is in the range of their rolling bearing surface arrangements 8th on both sides 6 . 7 each one of the two leadership units 26 . 27 flanked. The two leadership units 26 . 27 lie in the axial direction of the longitudinal axis 3 expediently at the same height.

Each circulation channel 38 is at the guide rail 2 facing front 42 of the leadership body 35 with one as a working slot 43 designated slot-like opening provided by the currently located in its area rolling bearing elements 36 can project with a portion of its circumference to the outside, as for example in 6 and 7 is illustrated. The one with the working slot 43 provided length section of the circulation channel 38 is from one to the guide body 35 formed wall surface leading to a rolling bearing surface arrangement 44 of the leadership body 35 belongs. Located in the area of the working slot 43 located rolling bearing elements 36 can be attached to the rolling bearing surface arrangement 44 of the leadership body 35 in the axial direction of the transverse axis 18 support.

Thus, there is a pertinent arrangement that each of the two on the guide rail 2 trained rolling bearing surface arrangements 8th one on the guide body 35 the associated guide unit 26 . 27 trained rolling bearing surface arrangement 44 in a direction indicated by a double arrow transverse direction 45 opposite, the transverse direction 45 with the axial direction of the two transverse axes 4 . 18 coincides. In each case a plurality of roller bearing elements 36 is between facing rolling bearing surface arrangements 8th . 44 the guide rail 2 and a respective executive body 35 arranged. They are through the working slot 43 passing through rolling bearing elements 36 in each case both on the rolling bearing surface arrangement 44 as well as on the rolling bearing surface arrangement 8th at. The leadership system is a total of play, because the leadership units 26 . 27 relative to the guide rail 2 in the transverse direction 45 are biased, so that the aforementioned rolling bearing elements 36 each biased to the two associated Wälzlagerflächenanordnungen 8th . 44 issue. Regardless of this play-free system are the rolling bearing elements 36 able to engage both associated rolling bearing surface arrangements 8th . 44 to shift when the carriage 14 when using the linear guide device 1 a linear movement 15 in the axial direction of the longitudinal axis 3 performs.

In the linear guide device 1 of the embodiment is each guide unit 26 . 27 with two circulation rolling bearing units 37 equipped, each having a plurality of rolling bearing elements 36 exhibit. Accordingly, each rolling bearing surface assembly settles 8th . 44 from two in the axial direction of the Hochachsen 5 . 16 spaced rolling bearing surfaces together, each with the rolling bearing elements 36 one of the two associated circulation rolling bearing units 37 cooperate. In an embodiment not shown, each guide unit contains 26 . 27 only a single circulation rolling bearing unit 37 so that each rolling bearing surface arrangement 8th . 44 also has only one rolling bearing surface.

The bias between the guide units 26 . 27 and the guide rail 2 results from the fact that between the two Wälzlagerflächenanordnungen 8th the guide rail 2 existing transverse distance "A" is slightly greater than that in the axial direction of the transverse axis 18 measured clear distance "LA" between the rolling bearing elements 36 the two leadership units 26 . 27 not on the guide rail 2 mounted state of the guide carriage 14 , The consequence of this distance difference, which is preferably in the micrometer range, is an in 1 dash-dotted lines indicated elastic deflection 46 of the carriage body 32 , due to which the U-shaped guide carriage 14 is slightly spread in its transverse direction, so that the guide units 26 . 27 by the effective, elastic restoring force from opposite sides to the two Wälzlagerflächenanordnungen 8th the guide rail 2 be pressed. The bias in the transverse direction 45 occurs when the previously assembled guide carriage 14 in the axial direction of the longitudinal axis 3 on the previously provided guide rail 2 is postponed.

The guide carriage 14 is a tightly assembled assembly that houses the carriage body 32 and the two before assembling the guide carriage 14 individually available leadership units 26 . 27 includes. The leadership units 26 . 27 are with their leadership bodies 35 on the carriage body 32 immovably attached.

In the preferred embodiment, each guide unit 26 . 27 in the area of one of the two lateral edge sections 33 . 34 of the carriage body 32 to the bottom 28 of the carriage body 32 stated. It is provided in particular that each guide unit 26 . 27 with the front 42 opposite and therefore from the guide rail 2 facing away back 47 of the leadership body 35 at least substantially flush with the adjacent, in the axial direction of the transverse axis 4 oriented side surface 48 of the adjacent carriage body 32 runs. The as a joining area 52 designated contact area between the top 53 every leadership body 35 and the bottom 28 of the carriage body 32 extends outwards to the back 47 and the side surface 48 where he is in a parallel to the longitudinal axis 17 running joint line 54 expresses over its entire axial length of the associated guide body 35 extends. Along this joint line 54 runs a weld 55a that one the guiding body 35 with the carriage body 32 cohesively connecting welded joint 55 Are defined. In this way, every leader body 35 cohesively on the carriage body 32 attached.

In addition, every leader body 35 expediently also with at least one and in the embodiment with a plurality of screw connections 56 at the carriage body 32 fixed. The screw connection 56 Tensioning the guide body 35 with the carriage body 32 in the axial direction of the vertical axis 16 non-positively together.

Preferably, each screw results 56 from a fixing screw 57 that of the bottom 28 opposite top 58 in a carriage body 32 heightwise penetrating mounting hole 62 is plugged in and the one with the bottom 28 from the carriage body 32 outstanding threaded shaft 63 in a likewise parallel to the vertical axis 16 running threaded hole 64 of the carriage body 32 is screwed. A screw head 65 the fixing screw 57 supports itself from above on the slide body 32 from, in particular in a recessed diameter extension of the mounting hole 62 so when tightening the mounting screw 57 the guide body 35 from below firmly to the carriage body 32 is pressed.

Exemplary are per management unit 26 . 27 two such screw connections 56 present, in the axial direction of the longitudinal axis 17 are arranged at a distance from each other.

Because that at every leadership unit 26 . 27 the respectively associated at least one screw connection 56 in the axial direction of the transverse axis 18 spaced from each other the same guide unit 26 . 27 relevant welding connection 55 is arranged even in the sense of the double arrow 66 on the carriage body 32 attacking tilting forces ensures that the guide body 35 always over the entire surface at the bottom 28 of the carriage body 32 stay put on. The screw connections 56 secure the relative position between the carriage body 32 and the guide body 35 against torques associated with the welded joint 55 as a center between the carriage body 32 and the guide body 35 may occur.

As an alternative or additional material connection would also be an adhesive bond in the joint area 52 possible.

The diameter of the mounting hole 62 is expediently slightly larger than the diameter of itself in the mounting hole 62 extending length portion of the fastening screw 57 , This makes it possible, the relative position between each guide body 35 and the carriage body 32 in the plane of the joining area 52 to vary slightly, as long as no welded joint 55 or another material connection was made and as long as the fixing screws 57 not yet tightened.

An explanation of a preferred manufacturing method of the linear guide device now follows 1 at.

Initial state on the part of the linear guide device 1 are provided individual components in the form of the guide rail 2 , the carriage body 32 , the leadership unit 26 . 27 and optionally the fixing screws 57 , In addition, a mounting rail 67 provided, which is used for the guide carriage 14 independent of the guide rail 2 assemble. The mounting rail 67 has a longitudinal axis 68 , a perpendicular transverse axis 69 and one to both the longitudinal axis 68 as well as the transverse axis 69 right-angled vertical axis 70 ,

Because the mounting rail 67 only the assembly of the guide carriage 14 serves, its length can be adjusted to the length of the guide carriage 14 restrict, but is expediently at least slightly larger. Basically, but the overall length of the mounting rail 67 any.

The mounting rail 67 has two parallel to the longitudinal axis 68 extending and in the axial direction of the transverse axis 69 oppositely oriented longitudinal sides 73 . 74 , On each of these long sides 73 . 74 is a mounting roller bearing surface assembly 75 , which are parallel to the longitudinal axis 68 extends and which is expediently the same design as one on the guide rail 2 located rolling bearing surface arrangement 8th , Preferably, the mounting rolling bearing surface arrangement 75 in one to the longitudinal axis 68 rectangular plane the same contour as the rolling bearing surface arrangement 8th in the to the longitudinal axis 3 right-angled plane. This is in particular a concave contour.

The two mounting rolling bearing surface arrangements 75 are arranged at a certain transverse distance "B" to each other, wherein the transverse distance "B" in the axial direction of the transverse axis 69 is measured. This transverse distance "B" is smaller, and in particular only slightly smaller than that between the two Wälzlagerflächenanordnungen 8th the guide rail 2 existing transverse distance "A". In other words, the guide rail has 2 in the field of rolling bearing surface arrangements 8th a slightly larger width than the mounting rail 67 in the field of mounting rolling bearing surface arrangement 75 , The dimensional difference is very small and is expediently only in the range of a few micrometers.

The mounting rail 67 is used as a template, around the guide slide 14 is assembled and the no part of the finished linear guide device 1 represents. In particular, it can be used several times to guide carriages 14 to assemble in any number one after the other.

After the provision of the mounting rail 67 the two become a leadership unit pair 30 forming leadership units 26 . 27 with her front 42 ahead according to arrows 76 in 4 in the transverse direction of the mounting rail 67 to each one of the two mounting rolling bearing surface arrangements 75 scheduled or created. This is done in not yet on the carriage body 32 attached state and in particular not at all with the carriage body 32 Connected state, so each individually.

In principle, could be in the preparation of the guide units 26 . 27 also already a certain loose prefixing with respect to the carriage body 32 present, however, the relative movements in the transverse direction 45 allows.

Already when applying to the mounting rolling bearing surface arrangements 75 or immediately thereafter becomes according to 5 on every guiding body 35 an indicated by an arrow pressure force 77 exercised by the leadership unit 26 . 27 in the transverse direction of the mounting rail 67 to the associated mounting rolling bearing surface assembly 75 is pressed. The compressive force is chosen at least so strong that on the front 42 from the guide body 35 outstanding rolling bearing elements 36 both on the rolling bearing surface arrangement 44 of the leadership body 35 as well as on the opposite mounting rolling bearing surface arrangement 75 the mounting rail 67 without play.

The pressure force 77 is expediently with the aid of at least one pressure tool 78 generated, which may be, for example, a vise-like clamping device.

In such from opposite longitudinal sides forth to the mounting rail 67 pressed state of the guide units 26 . 27 corresponds to the clear distance "LA" between the rolling bearing elements 36 which is in the transverse direction 45 opposite guide units 26 . 27 through the mounting rail 67 predetermined transverse distance "B" of the mounting rolling bearing surface arrangements 75 , This clear distance "LA" is thus slightly smaller than the transverse distance "A" between the two rolling bearing surface arrangements 8th the guide rail 2 ,

Next is the carriage body 32 on the guide bodies 35 the two leadership units 26 . 27 attached, so that the relative position between the same leadership unit pair 30 belonging leadership bodies 35 at least in the transverse direction 45 is immovably fixed. In this context, first according to 6 the carriage body 32 according to arrow 79 with its bottom 28 ahead of the tops 53 both guide body 35 stated. Here are the two guide units 26 . 27 still by the pressure force 77 against the mounting rail 67 biased.

It is understood that the contour of the mounting rolling bearing surface arrangements 75 not with that of the rolling bearing surface arrangements 8th the guide rail 2 must match. Ultimately, all that matters is the assembly rolling bearing surface arrangements 75 form so that their transverse distance "B" the desired clearance "LA" between the rolling bearing elements 36 Are defined.

Next, as in 7 is illustrated, with continuing applied compressive force 77 the screw connections 56 and / or the welds 55 produced. Appropriately, the screw 56 in front of the respective associated welded connection 55 realized.

Every screw connection 56 results from having a fixing screw 57 from above into a mounting hole 62 introduced and in the subsequent threaded hole 64 is screwed in. Tighten the fixing screws 57 affects the location of the leadership units 26 . 27 not as these as mentioned continue to the mounting rolling bearing surface arrangements 75 be pressed.

For the realization of the welded connection 55 be one or more in 7 dash-dotted lines indicated welding equipment 81 used.

Preferably, the weld is limited 55 on a weld 55a running along the joint line 54 runs.

There is a possibility of every leader body 35 additionally or alternatively to the screw connections 56 and the welded joint 55 in the joining area 52 large area with the carriage body 32 to stick together.

In an embodiment not shown, the guide body 35 each with only a single connection on the carriage body 32 fastened, for example, only with at least one screw 56 , with only one welded joint 55 or with only one adhesive connection.

The 8th and 9 illustrate an arrangement in which the finished assembled carriage 14 still on the mounting rail 67 sitting, for the pressure force 77 responsible printing tools 78 however were removed. In this state, the finished guide carriage 14 relative to the mounting rail 67 in the axial direction of its longitudinal axis 68 be moved arbitrarily.

To the linear guide device 1 finish, the guide carriage 14 from the mounting rail 67 removed and on the guide rail 2 placed. Both are done in particular by axial relative movements with respect to the guide carriage 14 and the respective rail 67 . 2 ,

An advantageous possibility for repositioning the guide carriage 14 from the mounting rail 67 to the guide rail 2 is the two rails 67 . 2 according to 10 and 11 axially aligned immediately axially abutting one another, so that in each case a mounting rolling bearing surface arrangement 75 with one of the rolling bearing surface arrangements 8th flees. Then, by according to arrow 82 illustrated axial displacement of the guide carriage 14 from the mounting rail 67 pushed down and at the same time on the subsequent axial alignment guide rail 2 postponed.

When sliding the guide carriage 14 on the guide rail 2 automatically sets the desired defined preload between the guide carriage 14 and the guide rail 2 in the field of leadership units 26 . 27 one. This results from the fact that the space defined by the clearance "LA" between the two guide units 26 . 27 is widened because the transverse distance "A" between the rolling bearing surface arrangements 8th the guide rail 2 is slightly larger than the transverse distance "B" between the mounting rolling bearing surface assemblies 75 the mounting rail 67 ,

Because the leadership units 26 . 27 immovably firmly on the carriage body 32 are fixed, goes with the expansion of said gap or the slight spreading apart of the guide units 26 . 27 of the leadership unit pair 30 a slight elastic bending of the carriage body 32 accompanied, resulting in an elastic restoring force results, from which results in the desired defined bias of the bearing system.

The 12 and 13 show a condition in which the guide carriage 14 from the mounting rail 67 removed and on the guide rail 2 is pushed, so that the linear guide device 1 is completed. The mounting rail 67 can now according to arrow 83 taken away and for the reassembly of a guide carriage 14 be used.

In an unillustrated procedure, the finished guide carriage becomes 14 from the mounting rail 67 removed, but not directly on a guide rail 2 put on, but until the completion of a linear guide device 1 stored elsewhere. This storage for the purpose of temporary storage can per carriage 14 quite individual. However, it is particularly advantageous if the storage of the guide carriage 14 until the final assembly of the linear guide device 1 on a specially provided storage rail, the type of the mounting rail 67 may correspond, but must be made less accurate than the mounting rail 67 so that it is much cheaper to produce. While the mounting rail 67 is preferably made very precisely from metal and in particular made of steel, the storage rail may for example also consist of a plastic material.

With appropriate length can easily on a storage rail several guide slide 14 stored at the same time and up to the union with a guide rail 2 be stored.

The final assembly of a linear guide device 1 based on an intermediate guide carriage 14 takes place in particular in a comparable manner as the already described transfer between the mounting rail 67 and the guide rail 2 , It is therefore expediently the storage rail in axial alignment with the associated guide rail 2 arrange so that the relevant carriage 14 only has to be moved axially to simultaneously pulled down axially from the storage rail and pushed axially onto the guide rail.

The described method is also suitable for the production of linear guide devices 1 , with several pairs of guide units 30 are equipped. For example, a guide carriage 14 two guide unit pairs arranged successively in its longitudinal direction 30 have, so that with each rolling bearing surface arrangement 8th two leadership units cooperate.
