    The invention relates to a linear guide device, comprising at least one linear guide unit having a housing defining an annular, self-contained circulation channel, the plurality of successively arranged in the Umlaufkanallängsrichtung, designed to execute an oriented in the Umlaufkanallängsrichtung orbital rolling elements wherein the circulation channel has a Abstützkanalabschnitt, the longitudinal side has a partial penetrating the rolling bearing elements located in the Abstützkanalabschnitt enabling longitudinal working slot.
    A known from US 4 557 530 linear guide device of this type includes a plate-shaped linear guide unit with a multi-part housing in which an annular self-contained circulation channel is formed. In the circulation channel is a plurality of spherical roller bearing elements, which protrude partially in the region of a Abstützkanalabschnittes of the circulation channel from the circulation channel in order to be able to cooperate with a leading body. Thus, the rolling bearing elements do not fall out of the Abstützkanalabschnitt, extends along the Abstützkanalabschnittes a retaining wire which bridges the currently located in the Abstützkanalabschnitt roller bearing elements and is inserted with its end portions in grooved socket portions of the housing.
    From EP 2 682 619 A2 a linear guide unit is known, which has a multi-part housing in a height direction, wherein a middle part of the housing is arranged between two housing covers and limited together with each housing cover equipped with rolling bearing elements circulation channel. A linear guide unit of similar construction also discloses WO 2014/005604 AI.
    DE 10 2004 011 625 B4 discloses a trained as a linear actuator linear guide device comprising a base body and a means of rolling bearing elements on the base linearly displaceably guided slide body.
    The invention has for its object to provide a linear guide device whose at least one linear guide unit is simple and inexpensive to produce.
    To solve this problem is provided in conjunction with the features mentioned above, that the circulation channel has a trained for introducing the rolling bearing elements in the circulation channel mounting opening, the edge of at least one of the introduced rolling bearing elements on a falling out of the circulation channel hindering retaining element is limited wherein the retaining element for the temporary widening of the mounting opening on a the introduction of the rolling bearing elements in the circulation channel permitting Mass while remaining on the housing of the linear guide unit relative to the housing of the linear guide unit is resilient or movable.
    In this way, the rolling bearing elements can be conveniently introduced after the previous assembly of the housing of the linear guide unit in the associated circulation channel. The circulation channel has at least one point of its longitudinal extension a mounting opening, which is bordered by a holding element, so that their free cross section is less than the cross section of the rolling bearing elements. In the circulation channel arranged rolling bearing elements are therefore retained by the retaining element and prevented from falling out through the mounting hole. To introduce the rolling bearing elements in the circulation channel, the holding element can be reversibly deformed or moved so that it temporarily releases a cross section of the mounting hole, which is sufficiently large to allow the passage of the rolling bearing elements to be mounted. Depending on the configuration of the holding element, this is possible in that either manually or by means of other external forces is temporarily acted upon by the holding element or that the rolling bearing elements are in the context of a snap action, in which the holding element elastically yielding momentarily, are hineindrückbar in the circulation channel.
    It is particularly advantageous if the mounting hole is formed directly from the Abstützkanalabschnitt of the circulation channel associated working longitudinal slot, as then an additional, separate mounting hole is unnecessary and directly the working longitudinal slot during assembly of the linear guide unit as a mounting hole for introducing the rolling bearing elements usable is. To the strength of the retaining element normally no particularly high demands are made, because in most cases the retaining function exerted by the retaining element is required only until the linear guide unit is installed as intended and located in the region of Abstützkanalabschnittes rolling bearing elements on a guide surface leading to one abut external counter body and thereby retained in Abstützkanalabschnitt. Therefore, the holding element can usually be realized inexpensively.
    Since the holding element also remains in the process of introducing the rolling bearing elements on the housing of the linear guide unit, its handling is extremely simple. In order to allow the temporary widening of the mounting opening, the retaining element is preferably mounted as a whole movably on the housing or it has a sufficient flexibility, for example by having at least partially elastomeric resilient properties.
    Advantageous developments of the invention will become apparent from the dependent claims.
    Conveniently, the holding member is arranged on the housing of the linear guide unit, that it occupies an unused state, the rolling bearing elements located in the circulation channel from falling out of the order to run hindering holding position and for introducing the rolling bearing element in the circulation channel temporarily against a restoring acting spring force is movable in a release position. If a roller bearing element has passed through the temporarily extended mounting opening, the retaining element can automatically return to the holding position due to the resetting spring force, in which the roller bearing elements located in the circulation channel are secured against loss.
    A particularly simple handling results when the holding element is pivotally mounted on the housing.
    It is further advantageous to connect the retaining element integrally with the housing. The production proves to be particularly cost-effective in this case. In particular, in this context, it is expedient if the holding element is connected via at least one film hinge pivotally movable with the housing. The film hinge manifests itself, in particular, in at least one material web connecting the holding element to the housing, which has a reduced wall thickness with respect to the adjacent regions of the holding element and of the housing and is elastically bendable.
    The holding element is preferably formed strip-shaped and arranged so that it extends along a linear length portion of the circulation channel. In particular, the holding element extends along the support channel section of the circulation channel, which preferably has a linear extension.
    Conveniently, the mounting opening is bordered by only a single movable support member. An edge region of the mounting opening opposite the movable retaining element is expediently formed by a rigid component of the housing.
    The circulation channel expediently extends in a channel plane. During their revolution, the rolling bearing elements in this channel plane to run around. The housing has a vertical axis perpendicular to the channel plane and preferably has a multi-part structure, wherein it is composed in particular of a carrier element and of a in the Achsrich direction of the vertical axis attached to the carrier element cover element. Together, the support member and the lid member limit the rolling bearing element receiving the circulation channel.
    The holding element is expediently arranged on the cover element. This can be realized in a particularly cost-effective manner by virtue of the fact that the integral structural unit consisting of the cover element and the carrier element consists of a plastic material.
    The cover element and the carrier element are preferably fixed to one another by means of a snap connection device. The snap connection device is in particular designed such that cover element and carrier element can be joined together in the axial direction of the vertical axis and can be locked together directly during assembly. In this way, a cost-effective cohesion of the housing without the use of additional fasteners such as screws or glue can be realized.
    The Abstützkanalabschnitt is conveniently limited by a Abstützflache, by which the rolling bearing elements are supported against external forces and on which roll the rolling bearing elements in their orbital motion. This support surface is expediently formed exclusively on the carrier element. The carrier element preferably consists of a metal having sufficient hardness, in particular of a hardened copper beryllium material.
    The linear guide device may have only a single linear guide unit or a plurality of linear guide units. Preferably, the linear guide unit is always used in pairs, wherein each linear guide unit pair two linear guide units are arranged alongside each other.
    A particularly advantageous constructed linear guide device has a base body and a mediated by at least one linear guide unit on the base linearly displaceable slide body. Particularly expedient is a structure in which the base body is part of a drive unit which has on the carriage engaging, electrically and / or by fluid force actuatable drive means, so that the carriage is actively driven to a guided linear movement relative to the base body.
    A linear guide unit is conveniently fastened by means of its housing to a base body of the linear guide device. For example, the housing of the linear guide unit can be screwed to the base body. In order to ensure a cost-effective manner a backlash-free interaction between the linear guide unit and a leading to Schlittenkörperzu, between the body of the linear guide device and the housing of the linear guide unit expediently incorporated a biasing device, which has a clamping wedge, with the help of the housing of the linear guide unit a bracing can be exerted with the carriage body causing biasing force before the housing is attached to the main body of the linear guide device.
    The invention will be explained in more detail with reference to the accompanying drawings. In this show:

    The illustrated in Fig. 1 to 3 linear guide device 1 has a base body 2 and a on the base body 2 by means of two linear guide units 3 of the linear guide device 1 linearly displaceably guided slide body. 4
    The linear guide device 1 has a main axis 5, which is in particular about the longitudinal axis of the linear guide device 1. The carriage body 4 can perform in the axial direction of the main axis 5, indicated by a double arrow, reciprocating linear motion 6.
    Not necessarily, but preferably, the linear guide device 1 represents a linear drive la, which applies to the embodiment. In this case, the main body 2 is part of a drive unit 7, which also has drive means 8 which are drivingly coupled to the carriage body 4. These drive means 8 are preferably of an electrically and / or by fluid force and in this case in particular pneumatically actuated type. For example, the drive means 8 comprise an end face protruding from the main body 2 drive rod 8a, which is connected within the body 2 with a pneumatically or hydraulically loadable drive piston and outside the base body 2 is fixed to the carriage body 4. The drive rod 8a is drivable for a drive movement in the axial direction of the main axis 5, resulting in the linear movement 6 of the carriage body 4 results.
    Base body 2 and slide body 4 are arranged one above the other in the axial direction of the vertical axis 12 and overlap in the axial direction of the main axis 5. The linear guide units 3 are in the axial direction of the vertical axis 12 between the base body 2 and the carriage body 4 and preferably attached to the base body 2.
    Each linear guide unit 3 has a longitudinal axis 13 and is arranged with respect to the main axis 5 parallel alignment of its longitudinal axis 13 on the base body 2.
    Each linear guide unit 3 has a housing 14, which is also referred to below for better distinction as a guide housing 14. In the interior of the guide housing 14 an annular self-contained circulation channel 15 is formed, which extends in a below referred to as channel plane 16 level. The circulation channel 15 is filled with a plurality of roller bearing elements 17, which are arranged in succession in the longitudinal direction of the circulation channel 15, which is referred to below as the circular channel longitudinal direction 18. The rolling bearing elements 17 are accommodated with play in the circulation channel 15 in such a way that they can execute a circulation movement 22 in the circumferential channel longitudinal direction 18 relative to the guide housing 14, wherein they roll on the wall of the circulation channel 15.
    The rolling bearing elements 17 are preferably spherical. Other shapes are also possible, for example, cylindrical roller bearing elements 17th
    Apart from a slot-like opening, which is referred to as working longitudinal slot 23, the circulation channel 15 is closed all around by the guide housing 14. The working longitudinal slot 23 extends along a longitudinal section of the circulation channel 15, which is a Abstützkanalabschnitt 24th acts, which has a linear extension and in particular runs parallel to the longitudinal axis 13.
    The Abstützkanalabschnitt 24 is bounded alongside of a formed on the guide housing 14, in cross-section concavely curved support surface 25. The support surface 25 faces the working longitudinal slot 23. Those roller bearing elements 17 which are arranged in their circulation movement 22 within the Abstützkanalabschnittes 24, support zen with a located within the Abstützkanalabschnittes 24 outer peripheral portion of the support surface 25 and protrude partially, with a better distinction as a guide portion 26 designated section, by the working Longitudinal slot 23 through out of the circulation channel 15 out.
    In its intended use, the linear guide unit 3 is mounted so that the rolling bearing elements 17 abut with their working longitudinal slot 23 passing through guide portions 26 on a guide surface 27 of the leading carriage body 4. The guide surface 27 has a linear extension and is in particular formed by the boundary surface of a formed in the carriage body 4 groove-like depression. When the carriage body 4 executes the linear movement 6, the guide surface 27 runs along the guide portions 26 of the rolling bearing elements 17, wherein the rolling bearing elements 17 are rotatively driven by friction and perform the orbital motion 22. Transverse forces exerted on the guide section 26 by the carriage body 4 are introduced into the support surface 25 by the rolling bearing elements 17, so that the carriage body 4 is supported in the channel plane 16 with respect to the guide housing 14 of the linear guide unit 3.
    By way of example, the support is in the axial direction of a transverse axis 28 of the linear guide unit 3, which is oriented in the channel plane 16 at right angles to the longitudinal axis 13.
    Each linear guide unit 3 is attached via its guide housing 14 to the base body 2 of the linear guide device 1. This is done, for example, by means of fastening screws 32, which pass through the guide housing 14 in the axial direction of a perpendicular to the channel plane 16 vertical axis 33 passing through fastening holes 34 and are screwed into the base body 2, so that the guide housing 14 is clamped to the base body 2 in the axial direction of the vertical axis 12.
    By way of example, the two linear guide units 3 in the axial direction of the longitudinal axis 5 at the same height at right angles to the longitudinal axis 5 are arranged side by side. They are oriented so that their working longitudinal slots 23 point away from each other. The carriage body 4 engages like a rider on the two linear guide units 3 and projects with a respective guide leg 35 in front of the Abstützkanalabschnitt 24 of a linear guide unit 3, so that in this Abstützkanalabschnitt 24 rolling bearing elements 17 abrollbar on one of the guide surfaces 27, which are formed on the associated guide leg 35 ,
    The linear guide device 1 is conveniently equipped with a biasing device 36, by means of which the linear guide units 3 to achieve a play-free contact with the associated guide surface 27 are braced before the guide housing 14 by means of fixing screws 32 or other fasteners immovably on the base body. 2 is determined.
    To the biasing means 36 includes a preferably integrally formed in the base body 2 support rib 37, which is formed on a pointing in the axial direction of the vertical axis 12 up to the carriage body 4 toward the upper body surface 38 of the body 2 and between the two at this upper body surface Submerged 38 adjacent linear guide units 3. In this case, the support rib 37 of a working longitudinal slot 23 opposite rear housing surface 42 of the guide housing 14 of a respective linear guide unit 3 with distance opposite. On the support rib 37 a plugged in cross-section U-shaped clamping wedge 43 which dips with one clamping leg 44 in one of the two located between the support rib 37 and the rear housing surfaces 42 spaces from above. At each clamping leg 44 is located on the adjacent linear guide unit 3 facing outside a wedge surface 45, which extends obliquely downward toward the upper body surface 38 and at the same time in the direction of the support rib 37. At least one clamping screw 46 passes through a two connecting legs 44 connecting connecting web 47 of the clamping wedge 43 and is screwed from above into the Abstützrippe 37, wherein it acts with a screw head 48 from above on the connecting web 47.
    When assembling the linear guide device 1, the two linear guide units 3 are first prefixed by means of fastening screws 32 on the base body 2, so that they remain movable in the channel plane 16 relative to the base body 2. Subsequently, the two clamping legs 44 are driven by actuation of the clamping screw 46 in the spaces between the support rib 37 and the guide housings 14, so that the linear guide units 3 pressed outward and play with the protruding from the Abstützkanalabschnitt 24 guide portions 26 of its rolling bearing elements 17 play with the guide surfaces 27 of previously mounted on the linear guide units 3 slide body 4 are clamped. An access hole 52 penetrating the carriage body 4 in the axial direction of its vertical axis 12 permits access to the screw head 48 required by means of a screwing tool.
    By the two clamping legs 44 are formed strip-shaped, they lie large area linear to the back of the guide housing 14 and also ensure an exactly parallel alignment of the linear guide units 3 with respect to the main axis 5 of the body. 2
    After the preloading measure is completed, the fastening screws 32, in turn, through trained in the carriage body 4 holes, tightened to fix the adjusted relative position between the guide housings 14 of the linear guide units 3 and the base body 2 immovable.
    Each linear guide unit 3 is designed so that the rolling bearing elements 17 are very easily introduced into the circulation channel 15, after previously the guide housing 14 was made or assembled.
    Thus, a generally difficult filling of the rolling bearing elements 17 in the still disassembled state of the guide housing 14 is unnecessary.
    Responsible for this functionality is a communicating with the circulation channel 15 mounting opening 53 of variable cross-section through which the rolling bearing elements 17 can be inserted under temporary expansion of the opening cross-section of the mounting hole 53 in the circulation channel 15.
    The mounting hole 53 is preferably formed slit-shaped and is preferably - which is true to the embodiment - formed directly from the working longitudinal slot 23 which extends along the Abstützkanalabschnittes 24 of the circulation channel 15.
    The mounting aperture 53 is bounded alongside two spaced apart first and second limiting elements 54, 55. While the first limiting element 54 is immovable with respect to the guide housing 14 and in particular a one-piece, rigid component of the guide housing 14, the second limiting element 55 is yielding or movable relative to the guide housing 14, so that the free cross section of the mounting opening 53 is variable. In this case, the second limiting element 55 acts as a holding element 56, which is able to prevent rolling bearing elements 17 placed in the circulation channel 15 in the region of the assembly opening 53 from falling out through the assembly opening 53 and consequently retaining it in the circulation channel 15.
    Preferably, and this also corresponds to the embodiment, the holding member 56 is relative to the guide housing 14 between a in Fig. 8 in solid lines and in Fig. 9 dotted illustrated holding position 56a and illustrated in Fig. 9 in solid lines release position 56b movable. In the mobility is in particular a pivoting, which results from the fact that the holding member 56 is pivotally mounted on the guide housing 14. The pivot axis 57 of the pivoting movement extends in the circumferential channel longitudinal direction 18 and extends exemplarily parallel to the longitudinal direction of the linear extension extending Abstützkanalabschnittes 24. Realized the pivoting mobility is realized in particular by a film hinge 58, which is a film-like thin and therefore flexible material web of the guide housing 14th is that integrally connects the holding member 56 with a rigid, immovable base portion 59 of the guide housing 14.
    The material thickness of the film hinge 58 is preferably less than the material thickness of the adjoining portion of the holding element 56 and the base portion 59th
    The film hinge 58 is a particularly advantageous possibility to realize hinge means 60, which ensure the indicated in 64 64 by a double arrow pivoting movement 64 of the support member 56. Other forms of implementation for the hinge means 60 are also possible, especially if the holding member 56 is not formed integrally with the guide housing 14, but is a separate component in this respect.
    The hinge means 60 may in principle extend over the entire length of the holding element 56 away. By way of example, they are shorter in this respect, so that they are projected axially on either side of each of an end portion of the holding member 56 in the axial direction of the pivot axis 57.
    The holding element 56 is expediently formed overall strip-shaped and extends along a linear length portion of the circulation channel 15, by way of example along the Abstützkanalabschnittes 24. Preferably, the holding member 56 assumes the above-mentioned holding position in an unactuated state. This is, if no roller bearing element 17 is placed in the circulation channel 15 in the region of the assembly opening 53, preferably by a voltage-neutral state. The cross-section of the mounting opening 53, which is more precisely the width of the mounting opening 53 defined by the mutual spacing of the two delimiting elements 54, 55, is smaller than the largest diameter of the rolling bearing elements 17. A in the region of the mounting opening 53 in the circulation channel 15 arranged rolling bearing element 17 - in the embodiment, this is the Abstützkanalabschnitt 24 - is located with its section of the largest diameter on the support surface 25 associated side of the mounting hole 53 and the working longitudinal slot 23 and thus of the two limiting elements 54, 55 together prevented from falling out at the circulation channel 15 or at a passage through the mounting hole 53. In this case, the holding member 56 may be slightly guided with respect to the voltage neutral position, so that it rests with slight bias on the adjacent rolling bearing element 17, which is not necessarily the case.
    When assembling the linear guide unit 3, the rolling bearing elements 17 can be introduced through the mounting hole 53 through one or more successively in the circulation channel 15. In this introduction process, the rolling bearing elements 17 enter the passageway 15 through the mounting opening 53 into the circulation channel 15 - in the exemplary embodiment into the support channel section 24 - with a passage movement 66 indicated by an arrow in FIG. 9, wherein the retaining element 6 has previously been moved into the release position and so on is kept in the release position until the introduction process of the rolling bearing elements 17 is completed. For this purpose, the movable holding member 56 can be held manually or with a suitable tool in the release position.
    The pivoting in the release position is conveniently accompanied by the structure of a restoring acting spring force, which seeks to zurückzuschwenken the holding member 56 in the holding position. Therefore, after inserting the rolling bearing elements 17, it is sufficient to simply release the holding element 56, so that it automatically returns to the holding position.

    The holding member 56 may also be resiliently movable so that the rolling bearing elements 17 can be pushed through the mounting hole 53 in the context of a snap action. In this case, the mounting opening 53 widens momentarily. In a non-illustrated embodiment, the support member 56 is resilient to allow for temporary expansion of the mounting aperture 53 and is at least partially made of a material having rubbery properties.
