Description

Technical Field

[0001] The present invention relates to a linear roller-profile rail guide, and particularly to a profile guide rail having at least four flat roller track surfaces extending in the longitudinal direction of the profile guide rail, and a guide carriage movable linearly in the longitudinal direction of the profile guide rail, including a base body, on which at least four flat roller track surfaces extending in the longitudinal direction of the profile guide rail are formed. The present invention relates to a linear roller-profile rail guide provided with a guide carriage.

Background Art

[0002] The above-described type of linear roller-profile rail guide has a number of applications, particularly for accurately and quickly positioning an object.

[0003] In this case, the guide carriage is supported on the profile guide rail by rollers. To enable linear movement of the guide carriage in the longitudinal direction of the guide rail, the guide carriage is provided with a plurality of (at least four) roller deflection devices, each of which includes an annularly extending roller circulation passage, and the roller circulation passage defines an annularly closed roller circulation path. Usually, one row of rollers is arranged in the roller circulation passage. In this case, when the guide carriage moves in the longitudinal direction of the profile guide rail, the rollers of each roller row are moved successively through the roller circulation passage, so that the rollers circulate along the annularly closed roller circulation path of each roller deflection device.

[0004] During the linear motion of the guide carriage along the longitudinal direction of the profiled guide rail, the rollers circulate through various sections of the roller circulation passage. In these sections, the rollers are subjected to mechanical loads of varying magnitudes. The rollers of the roller deflector each pass through, for example, a first section of the roller circulation passage, one ahead of the other. This first section is defined by one of the multiple roller track surfaces of the profiled guide rail and one of the roller track surfaces of the base, which extends (substantially) parallel to each of the multiple roller track surfaces of the profiled guide rail. Currently, the rollers within this first section of the roller circulation passage are each subjected to relatively large mechanical loads. This is because the diameter of the rollers is selected such that the rollers are sandwiched between the roller track surfaces of the profiled guide rail and the roller track surfaces of the base, which define the first section of the roller circulation passage, and are therefore subjected to mechanical stress. Therefore, the aforementioned first section of the roller circulation passage is called the "load zone" or "load-bearing zone" of the roller circulation passage. In contrast, the rollers currently circulating outside the aforementioned first section of the roller circulation passage are not exposed to mechanical load. Therefore, the area of ​​the roller circulation passage located outside the "load zone" is called the "unloaded" zone.

[0005] The linear roller-profile rail guides of the type described above have the characteristic of being suitable for applications where the guide carriage must withstand high loads perpendicular to the longitudinal axis of the profile guide rail. Furthermore, at least four roller deflectors may be arranged relative to one another so that the guide carriage can withstand high loads in any direction perpendicular to the longitudinal axis of the profile guide rail.

[0006] The linear roller-profile rail guides of the type described above typically exhibit so-called "stroke pulsation" of the guide carriage during its movement along the longitudinal direction of the guide rail. Stroke pulsation is a small movement of the guide carriage in the form of vertical movement perpendicular to the longitudinal direction of the guide rail, and this vertical movement occurs periodically during the longitudinal movement of the guide carriage, depending on the distance advanced along the longitudinal direction of the guide rail. The main cause of this type of stroke pulsation is that the guide carriage is currently supported on the guide rail only by the rollers currently located in the load zone of the roller circulation passage of each roller deflector of the guide carriage, and that the rollers are usually always mechanically preloaded in the load zone of each roller circulation passage. Based on this mechanical preload on the rollers, the base of the guide carriage and the guide rail also elastically deform locally near the rollers located in the load zone of each roller circulation passage. When the guide carriage moves along the longitudinal direction of the guide rail, the rollers circulate within the roller circulation passages of each roller deflector. In this case, the rollers of one of the multiple roller rows pass through the load zone of the roller circulation passage in one direction, one after the other. This causes individual rollers to enter the load zone from the unloaded zone of the roller circulation passage in succession at one end of the load zone, while at the other end of the load zone, individual rollers must exit the load zone in succession, one after the other, allowing them to re-enter the unloaded zone of the roller circulation passage. Therefore, when the guide carriage moves along the longitudinal direction of the guide rail, the number of rolling elements currently located in the load zone of one of the multiple roller circulation passages is not constant, but changes periodically according to the distance the guide carriage has traveled. This change in the number of rollers currently located in the load zone of the roller circulation passage leads to a change in the local elastic deformation of the guide carriage base and guide rail near the load zone of the roller circulation passage when the guide carriage moves along the longitudinal direction of the guide rail.This periodic change in the elastic deformation of the guide carriage base and guide rail ultimately has the effect that any point on the guide carriage performs a measurable periodic vertical movement (stroke pulsation) laterally relative to the longitudinal direction of the guide rail when the guide carriage moves along the longitudinal direction of the guide rail.

[0007] Such stroke pulsation of the guide carriage can have an amplitude of approximately 1-2 μm in conventional roller-profile rail guides. Stroke pulsation of this size order limits the positioning accuracy of the roller-profile rail guide, impairing its usability in a range of applications, such as positioning tools for high-precision machining of workpiece surfaces, or manufacturing smooth, flat surfaces by grinding components for low-noise transmission systems used in electromobility. Therefore, there is a need to significantly reduce stroke pulsation.

[0008] A simple concept for reducing stroke pulsation amplitude in roller-profile rail guides with pre-defined sized rollers is to increase the length of the guide carriage and the length of the load zone of the roller circulation passage, thereby increasing the number of rollers simultaneously located in the load zone of a single roller circulation passage. This concept is limited by the fact that it does not allow for the selection of a larger guide carriage length, and various requirements regarding the space situation for the placement of the guide carriage must be taken into consideration.

[0009] If a larger length of guide carriage (or a larger length of the load zone of the roller circulation passage) is not possible or undesirable, an alternative concept for reducing stroke pulsation is to configure each roller deflector as follows: multiple (e.g., two) rows of rollers are arranged side by side within the roller circulation passage of the roller deflector, so that when the guide carriage moves along the longitudinal direction of the guide rail, each of the multiple (e.g., two) rows of rollers circulates side by side through the roller circulation passage and, correspondingly, moves side by side through the load zone of the roller circulation passage.

[0010] Patent Document 1 exemplifies a roller-profile rail guide in which both the four roller track surfaces of the guide rail and the four roller track surfaces of the guide carriage have arc-shaped profiles in a cross-section perpendicular to the longitudinal direction of the guide rail. One embodiment of this roller-profile rail guide includes four roller deflectors, each containing two adjacent roller rows that can circulate side by side through a roller circulation passage. The rollers of the adjacent roller rows are connected to each other by belts made of synthetic resin, so that the rollers of one roller row are connected to the rollers of the other roller row via the belts. The belts are necessary to adjust the rotational axes of the rollers of the two adjacent roller rows relative to each other in different sections of the roller circulation passage. Furthermore, the belts hold the consecutive rollers of each of the two roller rows spaced apart relative to each other. This shape-shift roller steering device has the disadvantages of being time-consuming to install the belt and the belt being prone to wear.

[0011] Patent Document 2 describes a roller-profile rail guide comprising four flat roller track surfaces of a guide rail and four flat roller track surfaces of a guide carriage. This roller-profile rail guide includes four roller deflectors, each containing two adjacent roller rows that can circulate side by side through a roller circulation passage. Each roller deflector is in this case formed as a "full roller" type. That is, the rollers located within the roller circulation passage of the roller deflectors are not connected to each other by belts or chains, and furthermore, there is no technical means to separate or keep two consecutive rollers of one of the two roller rows from each other. Thus, the rollers can circulate within the roller circulation passage such that consecutive rollers can directly contact each other at their circumferential surfaces. Each pair of roller rows is located side by side within the roller circulation passage such that two adjacent rollers contact each other at their mutually facing end faces. This design has the drawback that rollers placed side-by-side can interfere with each other during circulation through the roller circulation path, for example, by blocking each other. This increases roller wear and reduces the roller's lifespan.

[0012] Patent Document 3 discloses a linear roller-profile rail guide comprising a linear profile rail and a guide carriage. This roller-profile rail guide has four roller circulation passages, each containing two rows of rollers arranged side by side. The rollers of these two rows circulate side by side and parallel to a single plane through their respective circulation passages when the guide carriage moves in the longitudinal direction of the profile rail. Multiple separator elements are arranged within each roller circulation passage, with each separator element arranged in a single row, one in front of the other, within each roller circulation passage. Each separator element is positioned between rollers arranged in a roller circulation passage, thereby separating or spacing out at least two consecutive rollers of one of two roller rows arranged in each roller circulation passage, separating or spacing out at least two consecutive rollers of the other of two roller rows arranged in each roller circulation passage, and separating one roller of one of two roller rows arranged in each roller circulation passage from two rollers of the other of two roller rows arranged in each roller circulation passage. Each individual separator element is connected to at least two consecutive rollers of one of the two roller rows arranged within each roller circulation passage, and to at least two consecutive rollers of the other of the two roller rows arranged within each roller circulation passage. In this case, when the guide carriage moves in the longitudinal direction of the profiled rail, all separator elements are made to move together in sync with the rollers arranged within each roller circulation passage, and furthermore, the rollers of one of the two roller rows arranged within each roller circulation passage are made to move in sync only with the rollers of the other of the two roller rows arranged within each roller circulation passage.Each individual separator element is molded such that it has multiple sections in which the separator element is arranged differently. That is, an insulating wall positioned between two rows of rollers, so that the insulating wall slides in contact with the end faces of the rollers of one of the two rows of rollers positioned within each roller circulation passage and with the end faces of the two rollers of the other row of rollers positioned within each roller circulation passage; a first separation section having two legs coupled to the insulating wall, the legs extending to the first side of the insulating wall, so that the legs surround one roller of one of the two rows of rollers positioned within each roller circulation passage in the area of ​​the roller's circumferential surface; and a second separation section extending to the second side of the insulating wall (located opposite to the first separation section), the second separation section extending between two consecutive rollers of the other row of rollers positioned within each roller circulation passage, separating these two rollers from each other. In this roller-profile rail guide, the insulating walls of the separator elements are connected to a first and second separation section, respectively. The presence of the first and second separation sections in each separator element means that the roller deflection mechanism of this roller-profile rail guide is not formed in a "full roller" configuration. This has the undesirable effect of reducing the maximum support capacity of the roller-profile rail guide due to the presence of each separation section. Furthermore, the installation of multiple separator elements is cumbersome when combined with multiple rollers arranged in two rows within the roller circulation passage. [Prior art documents] [Patent Documents]

[0013] [Patent Document 1] German Patent No. 112012003767 [Patent Document 2] Japanese Patent Application Publication No. 6-300039 [Patent Document 3] U.S. Patent Application Publication No. 2015 / 0159695 [Overview of the project] [Problems that the invention aims to solve]

[0014] The fundamental problem of this invention is to overcome the aforementioned drawbacks and improve a linear roller-profile rail guide equipped with a full-roller type roller deflector for multiple adjacent roller rows, thereby enabling improved guiding of adjacent roller rows with less wear on the rollers. [Means for solving the problem]

[0015] This problem is solved by a linear roller-profile rail guide having the features described in claim 1.

[0016] A linear roller-profile rail guide includes a profile guide rail having at least four flat roller track surfaces extending in the longitudinal direction of the profile guide rail, and a guide carriage disposed to be linearly movable in the longitudinal direction of the profile guide rail, the guide carriage including a base, the base having at least four flat roller track surfaces extending in the longitudinal direction of the profile guide rail.

[0017] The roller track surfaces of the profiled guide rail and the base body are arranged relative to each other as follows: that is, one roller track surface of each profiled guide rail and one roller track surface of each base body extend parallel to each other and are spaced apart from each other and facing each other. In this case, one roller track surface of each profiled guide rail and one roller track surface of each base body define a roller passage that supports the load.

[0018] The guide carriage has a full-roller type roller deflector for each individual roller passage of the load-bearing roller passage, for a plurality of adjacent roller rows arranged corresponding to each individual roller passage of the load-bearing roller passage, the roller deflector being mounted on a base and including an annularly extending roller circulation passage. This roller circulation passage defines an annularly closed roller circulation path for the adjacent roller rows. The roller circulation passage of the roller steering device includes a first section of the roller circulation passage which is identical to each individual roller passage among the roller passages that support the load; a second section of the roller circulation passage which is spaced apart from the first section of the roller circulation passage and extends longitudinally along the profile guide rail; and a third section and a fourth section of the roller circulation passage, wherein the third section of the roller circulation passage connects one end of the two opposite ends of the first section of the roller circulation passage to one end of the two opposite ends of the second section of the roller circulation passage, and the fourth section of the roller circulation passage connects the other end of the two opposite ends of the first section of the roller circulation passage to the other end of the two opposite ends of the second section of the roller circulation passage.

[0019] Each roller deflection device, which is positioned to correspond to each individual roller in the roller passage that supports the load, includes at least a first roller row and a second roller row, each having a plurality of rollers arranged in front of and behind each other, and the first roller row and the second roller row are positioned side by side within the roller circulation passage of the roller deflection device, so that when the guide carriage moves in the longitudinal direction of the profile guide rail, the rollers of the first roller row and the rollers of the second roller row move side by side along a closed annular roller circulation path, passing through the roller circulation passage parallel to a predetermined first plane.

[0020] According to the present invention, a roller deflection device formed in a full-roller shape, which is arranged corresponding to each individual roller passage of the roller passage that supports the load, has a separating web, which is fixed in position relative to a base and extends through the first section, second section, third section and fourth section of the roller circulation passage parallel to a first plane, and is positioned between the first roller row and the second roller row so as to spatially separate the rollers of the first roller row from the rollers of the second roller row. Each roller of the first roller row is adjacent to the first side surface of the separating web with its end face, so that each roller of the first roller row contacts the first side surface of the separating web when the guide carriage moves in the longitudinal direction of the profile guide rail. Furthermore, each roller in the second roller row is adjacent to the second side surface of the separation web at the end face of its respective roller, thereby guiding each roller in the second roller row to the separation web on the second side surface during the longitudinal movement of the guide carriage of the profile guide rail.

[0021] Therefore, each roller deflector is equipped with a separating web within the roller circulation passage, which separates at least two roller rows located within the roller circulation passage of the roller deflector from each other. Thus, the rollers of the first roller row and the rollers of the second roller row circulate side by side within the roller circulation passage, parallel to the first plane, and in this case, the rollers of the first roller row and the rollers of the second roller row do not come into contact with each other at their end faces. The separation webs of each roller deflection device are fixedly positioned relative to the base, so that when the guide carriage moves longitudinally along the profile guide rail, the rollers of the first and second roller rows circulate side by side along a closed annular roller circulation path through the roller circulation passage, and in this case, each roller of the first and second roller rows is able to move relative to the separation web (particularly relative to the separation web along the entire length of the separation web in the longitudinal direction of the roller circulation passage) when circulating along the closed annular roller circulation path. Therefore, compared to roller-profile rail guides known from Patent Document 2, roller wear is reduced by the installation of the separation webs. Furthermore, the separation webs act as lateral guide surfaces for the end faces of the rollers of at least one of the multiple roller rows. This enables more stable roller guiding.

[0022] In one embodiment of a linear roller-profile rail guide, a separating web is configured to be disposed within the roller circulation passage of a roller deflector device, where the separating web extends without gaps along the entire length of the roller circulation passage along an annularly closed roller circulation path for an array of rollers arranged side by side. Each roller of the first roller array is movable relative to the separating web along the entire extent of the separating web in the longitudinal direction of the roller circulation passage when the guide carriage moves in the longitudinal direction of the profile guide rail, whereby each roller is adjacent to the first side surface of the separating web at the end face of each roller. Correspondingly, each roller of the second roller array is movable relative to the separating web along the entire extent of the separating web in the longitudinal direction of the roller circulation passage when the guide carriage moves in the longitudinal direction of the profile guide rail, whereby the rollers of the second roller array are each guided at the second side surface of the separating web. This enables the guiding of all rollers by the same separating web with particularly high stability along the entire length of the annularly closed roller circulation path.

[0023] In one embodiment of a linear roller-profile rail guide, a base body has a first surface region, and the first surface region is configured to extend parallel to a first plane respectively along a first section of the roller circulation passage, and the rollers of the first roller array abut against the first surface region of the base body at the end faces of the respective rollers remote from the separating web in the first section of the roller circulation passage and are configured to be guided on the first surface of the base body when the guide carriage moves in the longitudinal direction of the profile guide rail.

[0024] In this embodiment, the first surface region of the base body ensures that the rollers of the first row of rollers can be guided with great lateral stability in the first surface region of the base body in the first section of the roller circulation passage, that is, in the load zone of the roller circulation passage. By the end faces of the rollers of the first row abutting against the separating web, the lateral guidance of the first row of rollers in the first surface region of the base body also indirectly causes the spatial attitude of the separating web to be stabilized, thereby enabling the guiding of the second row of rollers in the separating web with improved stability.

[0025] In a certain other embodiment of the linear roller-profile rail guide, the roller deflector device is composed of a plurality of individual parts and is configured such that the separating web has a plurality of sections, one of the plurality of individual parts includes a section of the separating web that extends over at least a part of the length of the first section of the roller circulation passage, and / or one of the plurality of individual parts includes a section of the separating web that extends over at least a part of the length of the second section of the roller circulation passage, and / or one of the plurality of individual parts includes a section of the separating web that extends over at least a part of the length of the third section of the roller circulation passage, and / or one of the plurality of individual parts includes a section of the separating web that extends over at least a part of the length of the fourth section of the roller circulation passage.

[0026] Thereby, the equipment of the separating web over the entire length of the roller circulation passage is simplified. The various different sections of the separating web can be realized with different materials from each other, for example, for the various different sections of the roller circulation passage. The parts of the roller deflector device and the sections of the separating web can be manufactured cheaply, for example, from plastic, for example, by injection molding.

[0027] In one embodiment of a linear roller-profile rail guide, each roller is formed rotationally symmetrically with respect to its longitudinal axis, and each roller is configured to have a diameter that varies in the direction of its longitudinal axis, so that the diameter of the roller has its maximum value in the central region between the opposite end faces of the roller, and the diameter decreases continuously and gradually in the direction of the longitudinal axis of the roller, with respect to the distance from the central region, starting from the central region between the opposite end faces. Furthermore, a separator web extends parallel to a first plane in a first section of the roller circulation passage of the roller deflector, in which case the separator web is made to have a height less than the maximum value of the roller diameter with respect to the roller track surface of the base body that defines the first section of the roller circulation passage of the roller deflector.

[0028] This ensures that the separating web can contact the end faces of the rollers in the first and second roller rows across their entire surfaces within the load zone of the roller circulation path, while the separating web does not come into contact with the roller track surface formed on the profiled guide rail.

[0029] In another embodiment of a linear roller-profile rail guide, the separator web is configured to extend parallel to a first plane such that, in a first section of the roller circulation passage of the roller deflector, the separator web has an end section that is separated from one of the roller track surfaces of the base body with respect to the roller track surface that defines the first section of the roller circulation passage of the roller deflector. In this case, the separator web has a first projection at the separated end section, which extends perpendicular to the first plane such that it extends beyond the roller of a first roller row adjacent to the first side surface of the separator web in the region of the circumferential surface of the roller adjacent to the first side surface of the separator web. Furthermore, the separation web has a second projection at a distant end section, which extends perpendicular to the first plane such that it extends beyond the rollers of a second roller row adjacent to the second side surface of the separation web in the region of the circumferential surface of these rollers adjacent to the second side surface of the separation web.

[0030] The arrangement of the first projections at the distant end sections of the separation web has the effect that, when the guide carriage is removed from the profile guide rail, the rollers of the first roller row located in the load zone of the roller circulation passage can be held in the guide carriage by the first projections.

[0031] Correspondingly, the arrangement of the second projections at the distant end sections of the separation web has the effect that when the guide carriage is removed from the profile guide rail, the rollers of the second roller row located in the load zone of the roller circulation passage can be held in place by the second projections on the guide carriage.

[0032] Another embodiment of a linear roller-profile rail guide is configured such that the separator web has a first groove on a first side of the separator web extending along the roller circulation path (or roller circulation passage) through which a lubricant for lubricating the rollers of a first roller row can be introduced into the roller circulation passage, and / or the separator web has a second groove on a second side of the separator web extending along the roller circulation path (or roller circulation passage) through which a lubricant for lubricating the rollers of a second roller row can be introduced into the roller circulation passage.

[0033] The first groove allows for the distribution of lubricant (e.g., lubricating oil or grease) along the roller circulation passage for lubricating the first roller row. Correspondingly, the second groove allows for the distribution of lubricant (e.g., lubricating oil or grease) along the roller circulation passage for lubricating the second roller row.

[0034] In another embodiment of a linear roller-profile rail guide, the separator web is made of plastic, or at least a portion of the separator web is made of plastic. Suitable plastics include those that guarantee high rigidity and low friction values, such as polyoxymethylene (also known as POM or polyacetal), for example.

[0035] Alternatively, it may be specified that the section of the separation web extending into the first section of the roller circulation passage is made of a metallic material, such as steel.

[0036] Further details of the present invention and, in particular, exemplary embodiments of the linear roller-profile rail guide according to the present invention will be described below with reference to the accompanying drawings. [Brief explanation of the drawing]

[0037] [Figure 1]This is a perspective view showing a linear roller-profile rail guide according to the present invention, comprising a profile guide rail and a guide carriage installed on the profile guide rail. [Figure 2] Figure 1 shows the roller-profile rail guide in a cross-section perpendicular to the longitudinal direction of the profile guide rail, illustrating the profile guide rail and guide carriage to show a sub-region of the four roller deflectors UV1 or UV2 for each of the two adjacent roller rows. [Figure 3] Figure 2 shows a diagram illustrating a roller-profile rail guide, but the guide rail itself is not shown. [Figure 4] This figure shows the roller-profile rail guide shown in Figure 1, in a longitudinal cross-section passing through one of the IV-IV lines shown in Figure 2, to illustrate the roller circulation passage UK1 of the roller steering device UV1 and the roller circulation passage UK2 of the roller steering device UV2. [Figure 5] Figure 1 is an exploded perspective view showing the roller-profile rail guide. [Figure 6] Figures 2 to 4 are three-dimensional diagrams showing the roller rows in the roller circulation passage UK1 of the roller steering device UV1 and the roller circulation passage UK2 of the roller steering device UV2. [Figure 7] This figure shows a magnified view of a portion of the guide carriage in the cross-sectional view shown in Figure 3. [Figure 8] This figure shows a magnified view of a portion of the guide carriage in the cross-sectional view shown in Figure 7. [Figure 9] This figure shows a plan view of one of the rollers in the roller steering device UV1 or UV2 shown in Figures 2 to 4, with the circumferential surface of the roller viewed from above. [Modes for carrying out the invention]

[0038] Unless otherwise specified, the same reference number is used for identical elements in the diagram.

[0039] Figure 1 shows a perspective view of a linear roller-profile rail guide 1 according to the present invention, which includes a profile guide rail 5 and a guide carriage 10 installed on the profile guide rail 5.

[0040] In this example, the profiled guide rail 5 has four flat roller track surfaces 6 and 7 extending in the longitudinal direction of the profiled guide rail 5. These roller track surfaces 5 and 6 are spatially distributed and formed on the sides 5.1 and 5.2 of the profiled guide rail 5 that are opposite each other. As can be seen from Figure 1, roller track surfaces 6 and 7 are formed on each side 5.1 and 5.2 of the profiled guide rail 5, respectively. On each side 5.1 and 5.2, each track surface 6 is positioned next to its respective roller track surface 7 and extends parallel to the roller track surface 7 with respect to the longitudinal direction of the profiled guide rail 5.

[0041] With respect to a cross-section perpendicular to the shaped guide rail 5, the roller track surfaces 6 and 7 formed on the side surface 5.1 are arranged relative to each other such that the roller track surface 6 extends perpendicularly to the roller track surface 7 in a cross-section perpendicular to the shaped guide rail 5 (as can be seen from the combination of Figures 1 and 2).

[0042] Correspondingly, the roller track surfaces 6 and 7 formed on the side surface 5.2 are arranged relative to each other such that the roller track surface 6 extends perpendicularly to the roller track surface 7 in a cross-section perpendicular to the shaped guide rail 5 (as can be seen from the combination of Figures 1 and 2).

[0043] The guide carriage 10 is installed on the profiled guide rail 5 such that it is positioned to move linearly along the longitudinal direction of the profiled guide rail 5. As can be seen in Figure 1, the guide carriage 10 includes, in particular, a base 11 and two end caps 12 attached to the base 11 at the end faces of the base 11 that are opposite each other with respect to the longitudinal direction of the profiled guide rail 5.

[0044] As can be seen in Figures 1 and 5, each end cap 12 has a number of inlet openings 13. These inlet openings 13 serve to supply lubricant to lubricate the rollers of the roller-profile rail guide 1. The lubricant supplied through the inlet openings 13 may be guided from the end cap 12 to the rollers of the roller-profile rail guide 1 inside the guide carriage 10, which will be explained in more detail below with reference to Figure 8.

[0045] Further details of the roller-profile rail guide 1 are described below with reference to Figures 2 to 9.

[0046] As can be seen from Figures 2 and 3, the base 11 of the guide carriage 10 has a U-shaped profile with two lateral legs 11.1 and 11.2 in a cross-section perpendicular to the longitudinal direction of the irregularly shaped guide rail 5.

[0047] The cross-sectional profile of the base 11 is shaped such that, when the guide carriage 10 of the profiled guide rail 5 is installed as shown in Figure 1, the upper section of the profiled guide rail 5, including the roller track surfaces 6,7 formed on both the side surface 5.1 and the side surface 5.2 of the profiled guide rail 5, is located within an intermediate chamber extending between the lateral legs 11.1, 11.2 of the U-shaped profile of the base 11.

[0048] The cross-sectional profile of the base 11 is shaped such that a first gap is formed between the lateral legs 11.1 of the base 11 and the side surface 5.1 of the profiled guide rail 5, and this first gap extends in the longitudinal direction of the profiled guide rail 5. Correspondingly, a second gap is formed between the lateral legs 11.2 of the base 11 and the side surface 5.2 of the profiled guide rail 5, and this second gap extends in the longitudinal direction of the profiled guide rail 5.

[0049] The first gap between the lateral legs 11.1 of the base 11 and the side surface 5.1 of the profile guide rail 5, and the second gap between the lateral legs 11.2 of the base 11 and the side surface 5.2 of the profile guide rail 5, serve to accommodate the rollers of the roller-profile rail guide 1. These rollers preferably support the guide carriage 10 on the roller track surfaces 6,7 of the profile guide rail 5 in order to enable the movement of the guide carriage 10 in the longitudinal direction of the profile guide rail 5.

[0050] As suggested by Figure 2, the roller-profile rail guide 1 is configured such that the guide carriage 10 and the profile guide rail 5 are formed symmetrically with respect to the symmetry plane SE shown in Figure 2 (the symmetry plane SE extends in the longitudinal direction of the profile guide rail 5 along the dashed line indicated by the symbol SE shown in Figure 2).

[0051] As shown in Figure 2, two flat roller track surfaces 20 and 21 extending in the longitudinal direction of the irregularly shaped guide rail are formed on the lateral legs 11.1 of the base body 11 (on the side of the lateral legs 11.1 facing the side surface 5.1 of the irregularly shaped guide rail 5).

[0052] With respect to a cross-section perpendicular to the shaped guide rail 5, the roller track surfaces 20 and 21 formed on the lateral legs 11.1 of the base body 11 are arranged side by side such that the roller track surface 20 extends perpendicularly to the roller track surface 21 in a cross-section perpendicular to the shaped guide rail 5.

[0053] Furthermore, as shown in Figure 2, two flat roller track surfaces 20 and 21 extending in the longitudinal direction of the irregularly shaped guide rail are formed on the lateral legs 11.2 of the base body 11 (on the side of the lateral legs 11.2 facing the side surface 5.2 of the irregularly shaped guide rail 5).

[0054] With respect to a cross-section perpendicular to the shaped guide rail 5, the roller track surfaces 20 and 21 formed on the lateral legs 11.2 of the base body 11 are arranged side by side such that the roller track surface 20 extends perpendicularly to the roller track surface 21 in a cross-section perpendicular to the shaped guide rail 5.

[0055] As shown in Figure 2, the roller track surfaces 20 and 21 formed on the lateral legs 11.1 of the base body 11 and the roller track surfaces 6 and 7 formed on the side surface 5.1 of the shaped guide rail 5 are arranged relative to each other as follows: -The roller track surface 6 formed on the side surface 5.1 of the irregularly shaped guide rail 5 and the roller track surface 20 formed on the lateral leg portion 11.1 of the base body 11 extend parallel to each other and are positioned opposite each other at a distance from each other, so that the roller track surface 6 formed on the side surface 5.1 of the irregularly shaped guide rail 5 and the roller track surface 20 formed on the lateral leg portion 11.1 of the base body 11 define a roller passage LK1 that supports the load, and -The roller track surface 7 formed on the side surface 5.1 of the irregularly shaped guide rail 5 and the roller track surface 21 formed on the lateral leg portion 11.1 of the base body 11 extend parallel to each other and are positioned opposite each other at a distance from each other, so that the roller track surface 7 formed on the side surface 5.1 of the irregularly shaped guide rail 5 and the roller track surface 21 formed on the lateral leg portion 11.1 of the base body 11 define a roller passage LK2 that supports the load.

[0056] As shown in Figure 2, the roller track surfaces 20 and 21 formed on the lateral legs 11.2 of the base body 11 and the roller track surfaces 6 and 7 formed on the side surfaces 5.2 of the shaped guide rail 5 are arranged relative to each other as follows: -The roller track surface 6 formed on the side surface 5.2 of the irregularly shaped guide rail 5 and the roller track surface 20 formed on the lateral leg portion 11.2 of the base body 11 extend parallel to each other and are positioned opposite each other at a distance from each other, so that the roller track surface 6 formed on the side surface 5.2 of the irregularly shaped guide rail 5 and the roller track surface 20 formed on the lateral leg portion 11.2 of the base body 11 define a roller passage LK1 that supports the load, and - The roller track surface 7 formed on the side surface 5.2 of the irregularly shaped guide rail 5 and the roller track surface 21 formed on the lateral leg portion 11.2 of the base body 11 extend parallel to each other and are positioned opposite each other at a distance from each other, so that the roller track surface 7 formed on the side surface 5.2 of the irregularly shaped guide rail 5 and the roller track surface 21 formed on the lateral leg portion 11.2 of the base body 11 define a roller passage LK2 that supports the load.

[0057] Furthermore, as shown in Figure 2, two through holes 30 are formed in the lateral leg portions 11.1 of the base body 11. These through holes 30, 31 are arranged side by side and each extends in the longitudinal direction of the shaped guide rail 5.

[0058] Correspondingly, two through holes 30 and 31 are also formed in the lateral leg portions 11.2 of the base body 11. These through holes 30 and 31 are arranged side by side and each extends in the longitudinal direction of the shaped guide rail 5.

[0059] As shown in Figures 2 to 4, the guide carriage 10 has a full-roller type roller deflector UV1 for each of the two roller passages LK1 that support the load, corresponding to each individual roller passage LK1 that supports the load, and for two adjacent roller rows RR1 and RR2, the roller deflector UV1 is attached to the base 11 and includes an annularly extending roller circulation passage UK1. This roller circulation passage UK1 defines an annularly closed roller circulation path for the adjacent roller rows RR1 and RR2. According to the drawings in Figures 2 to 4, the rollers belonging to roller row RR1, located in the circulation passage UK1 of the roller deflector UV1, are denoted by the letter R1, while the rollers belonging to roller row RR2 are denoted by the letter R2.

[0060] The roller deflector UV1 is formed in a "full roller" configuration, in which case, each pair of consecutive rollers R1 in the roller row RR1 are not held at a distance from each other by technical means, but rather the rollers R1 are made to circulate in the roller circulation passage UK1 so that the directly consecutive rollers R1 can come into contact with each other on their circumferential surfaces (as can be seen in Figures 4 and 6). Correspondingly, each pair of consecutive rollers R2 in the roller row RR2 are not held at a distance from each other by technical means, but rather the rollers R2 are made to circulate in the roller circulation passage UK1 so that the directly consecutive rollers R2 can come into contact with each other on their circumferential surfaces (as can be seen in Figures 4 and 6).

[0061] Furthermore, as suggested by Figures 2 to 4, the guide carriage 10 has a full-roller type roller deflector UV2 for each of the two aforementioned roller passages LK2 that support the load, corresponding to each individual roller passage LK2 of the load-supporting roller passage LK2, and for each of two adjacent roller rows RR1 and RR2, which are arranged side by side. The roller deflector UV2 is attached to the base 11 and includes an annularly extending roller circulation passage UK2. This roller circulation passage UK2 defines an annularly closed roller circulation path for the adjacent roller rows RR1 and RR2. According to the drawings in Figures 2 to 4, the rollers belonging to roller row RR1, which are arranged in the circulation passage UK2 of the roller deflector UV2, are indicated by the symbol R1, while the rollers belonging to roller row RR2 are indicated by the symbol R2.

[0062] The roller deflector UV2 is formed in a "full roller" configuration, in which case, each pair of consecutive rollers R1 in the roller row RR1 are not held at a distance from each other by technical means, but rather the rollers R1 are made to circulate in the roller circulation passage UK2 so that the directly consecutive rollers R1 can come into contact with each other on their circumferential surfaces (as can be seen in Figure 6). Correspondingly, each pair of consecutive rollers R2 in the roller row RR2 are not held at a distance from each other by technical means, but rather the rollers R2 are made to circulate in the roller circulation passage UK2 so that the directly consecutive rollers R2 can come into contact with each other on their circumferential surfaces (as can be seen in Figure 6).

[0063] As suggested by Figures 2 to 4, the roller circulation passage UK1 of each roller deflection device UV1 is -A first section UK1-1 which is identical to each individual roller passage LK1 of the roller passages LK1 that support the load, -A second section UK1-2 of the roller circulation passage UK1 is spaced apart from the first section UK1-1 of the roller circulation passage UK1 and extends through one of the through holes 30 provided in the base 11 in the longitudinal direction of the profile guide rail 5, -The third section UK1-3 and fourth section UK1-4 of the roller circulation passage UK1, wherein the third section UK1-3 of the roller circulation passage UK1 connects one end of the two opposite ends of the first section UK1-1 of the roller circulation passage UK1 to one end of the two opposite ends of the second section UK1-2 of the roller circulation passage UK1, and the fourth section UK1-4 of the roller circulation passage UK1 connects the other end of the two opposite ends of the first section UK1-1 of the roller circulation passage UK1 to the other end of the two opposite ends of the second section UK1-2 of the roller circulation passage UK1. It includes.

[0064] As suggested by Figures 2 to 4, the roller circulation passage UK2 of each roller deflection device UV2 is -A first section UK2-1 which is identical to each individual roller passage LK1 of the roller passage LK2 that supports the load, -A second section UK2-2 of the roller circulation passage UK2 is spaced apart from the first section UK2-1 of the roller circulation passage UK2 and extends through one of the through holes 31 provided in the base 11 in the longitudinal direction of the profile guide rail 5, -The third section UK2-3 and fourth section UK2-4 of the roller circulation passage UK2, wherein the third section UK2-3 of the roller circulation passage UK2 connects one end of the two opposite ends of the first section UK2-1 of the roller circulation passage UK2 to one end of the two opposite ends of the second section UK2-2 of the roller circulation passage UK2, and the fourth section UK2-4 of the roller circulation passage UK2 connects the other end of the two opposite ends of the first section UK2-1 of the roller circulation passage UK2 to the other end of the two opposite ends of the second section UK2-2 of the roller circulation passage UK2. It includes.

[0065] As suggested by Figures 2 to 4, each of the aforementioned roller deflection devices UV1 (arranged in correspondence with one of the roller passages LK1 that support the load) includes at least a first roller row RR1 and a second roller row RR2, the first roller row RR1 having a plurality of rollers R1 arranged in succession, and the second roller row RR2 having a plurality of rollers R2 arranged in succession, the first roller row RR1 and the second roller row RR2 are arranged side by side in the roller circulation passage UK1 of the roller deflection device UV1, and in this case, when the guide carriage 10 moves in the longitudinal direction of the profile guide rail 5, the rollers R1 of the first roller row RR1 and the rollers R2 of the second roller row RR2 circulate side by side along a closed annular roller circulation path, through the roller circulation passage UK1, parallel to a predetermined first plane E1 (shown in Figure 3).

[0066] As suggested by Figures 2 to 4, each of the aforementioned roller deflection devices UV2 (arranged in correspondence with one of the roller passages LK2 that support the load) includes at least a first roller row RR1 and a second roller row RR2, the first roller row RR1 having a plurality of rollers R1 arranged in succession, and the second roller row RR2 having a plurality of rollers R2 arranged in succession, the first roller row RR1 and the second roller row RR2 are arranged side by side in the roller circulation passage UK2 of the roller deflection device UV2, and in this case, when the guide carriage 10 moves in the longitudinal direction of the profile guide rail 5, the rollers R1 of the first roller row RR1 and the rollers R2 of the second roller row RR2 circulate side by side along a closed annular roller circulation path, through the roller circulation passage UK2, parallel to a predetermined first plane E2 (shown in Figure 3).

[0067] As Figures 2 to 4 suggest, the roller deflector UV1 and the roller deflector UV2 are each composed of a series of separate parts. For example, a section of the roller deflector UV1 formed on the lateral leg 11.1 or lateral leg 11.2 of the base body 11 extends through a through hole 30 provided in the lateral leg 11.1 or lateral leg 11.2 of the base body 11, while another section of the roller deflector UV1 formed on the lateral leg 11.1 or lateral leg 11.2 of the base body 11 extends along the roller track surface 20 in the lateral leg 11.1 or lateral leg 11.2, respectively. For example, a section of the roller deflector UV2 formed on the lateral leg portion 11.1 or lateral leg portion 11.2 of the base body 11 extends through a through hole 31 provided in the lateral leg portion 11.1 or lateral leg portion 11.2 of the base body 11, whereas another section of the roller deflector UV2 formed on the lateral leg portion 11.1 or lateral leg portion 11.2 of the base body 11 extends along the roller track surface 21 in the lateral leg portion 11.1 or lateral leg portion 11.2, respectively.

[0068] To clarify the spatial extension of the roller deflectors UV1 and UV2 located on the guide carriage 10, refer to Figure 5. Figure 5 shows an exploded view of the roller-profile rail guide 1. The diagram in Figure 5 shows a structural group 50 including all parts of the roller deflector UV1 to be located on the lateral leg 11.2 (removed from the leg 11.2) and all parts of the roller deflector UV2 to be located on the lateral leg 11.2. Furthermore, the diagram in Figure 5 also shows a structural group 51 including all parts of the roller deflector UV1 to be located on the lateral leg 11.1 (removed from the leg 11.1) and all parts of the roller deflector UV2 to be located on the lateral leg 11.1.

[0069] Figure 6 helps to clarify the arrangement of the first roller row RR1 and the second roller row RR2 in the roller deflection devices UV1 and UV2. Figure 6 shows a drawing of the structural group 50 or structural group 51 shown in Figure 5. In this case, certain parts that form the outer wall of the roller circulation passage UK1 or the outer wall of the roller circulation passage UK2 are not shown in Figure 6. Thus, in Figure 6, the arrangement of roller R1 of the first roller row RR1 and roller R2 of the second roller row RR2 can be confirmed in three dimensions.

[0070] As can be seen from Figures 4, 5, 6 to 8, each roller deflector UV1, which is positioned in relation to an individual roller passage LK1 of the load-supporting roller passage LK1, has a separation web TS. This separation web TS extends through the first section UK1-1, the second section UK1-2, the third section UK1-3, and the fourth section UK1-4 of the roller circulation passage UK1, parallel to the first plane E1, and is positioned between the first roller row RR1 and the second roller row RR2 so as to spatially separate the roller R1 of the first roller row RR1 from the roller R2 of the second roller row RR2.

[0071] The roller deflection device UV1 is attached to the base 11 such that (as can be seen from Figures 4 to 6) the separation web TS of the roller deflection device UV1 is fixed in position relative to the base 11.

[0072] Correspondingly, each roller deflector UV2, positioned in accordance with each individual roller passage LK2 of the load-supporting roller passage LK2, has a separation web TS, which extends through the first section UK2-1, the second section UK2-2, the third section UK2-3, and the fourth section UK2-4 of the roller circulation passage UK2, parallel to the first plane E2, and is positioned between the first roller row RR1 and the second roller row RR2 such that the separation web TS spatially separates the roller R1 of the first roller row RR1 from the roller R2 of the second roller row RR2.

[0073] The roller deflection device UV2 is attached to the base 11 such that (as can be seen from Figures 4 to 6) the separation web TS of the roller deflection device UV2 is fixed in position relative to the base 11.

[0074] In this example, the separation web TS of the roller deflection device UV1 is positioned within the roller circulation passage UK1 of the roller deflection device UV1, preferably such that the separation web TS extends seamlessly along the entire length of the roller circulation passage UK1 along an annularly closed roller circulation path for a row of adjacent rollers R1 or R2, RR1 or RR2.

[0075] In this example, the separation web TS of the roller deflector UV2 is positioned within the roller circulation passage UK2 of the roller deflector UV2, preferably such that the separation web TS extends seamlessly along the entire length of the roller circulation passage UK2 along an annularly closed roller circulation path for a row of adjacent rollers R1 or R2, RR1 or RR2.

[0076] As can be seen from Figures 4 and 6, the separation web TS of the roller deflector UV1 may consist of multiple sections, and the separation web TS of the roller deflector UV1 may have, for example, sections TS-1, TS-2, TS-3, and TS-4. Here, section TS-1 of the separation web TS extends over at least a portion of the length of the first section UK1-1 of the roller circulation passage UK1, section TS-2 of the separation web TS extends over at least a portion of the length of the second section UK1-2 of the roller circulation passage UK1, section TS-3 of the separation web TS extends over at least a portion of the length of the third section UK1-3 of the roller circulation passage UK1, and / or section TS-4 of the separation web TS extends over at least a portion of the length of the fourth section UK1-4 of the roller circulation passage UK1.

[0077] Correspondingly, the separation web TS of the roller deflector UV2 may consist of multiple sections, for example, the separation web TS of the roller deflector UV2 may have sections TS-1, TS-2, TS-3, and TS-4, wherein section TS-1 of the separation web TS extends over at least a portion of the length of the first section UK2-1 of the roller circulation passage UK2, section TS-2 of the separation web TS extends over at least a portion of the length of the second section UK2-2 of the roller circulation passage UK2, section TS-3 of the separation web TS extends over at least a portion of the length of the third section UK2-3 of the roller circulation passage UK2, and / or section TS-4 of the separation web TS extends over at least a portion of the length of the fourth section UK2-4 of the roller circulation passage UK2.

[0078] Furthermore, from Figures 4, 5, 6 to 8, it can be seen that each roller R1 of the first roller row RR1 is adjacent to the first side surface F1 of the separating web TS at the end face of each roller R1, and as a result, each roller R1 of the first roller row RR1 comes into contact with the first side surface F1 of the separating web TS when the guide carriage 10 moves in the longitudinal direction of the shaped material guide rail 5.

[0079] Furthermore, Figures 4, 5, and 6-8 suggest that each roller R2 of the second roller row RR2 is adjacent to the second side surface F2 of the separating web TS at the end face of each roller R2, thereby guiding each roller R2 of the second roller row RR2 along the second side surface F2 of the separating web TS during the longitudinal movement of the guide carriage 10 of the profile guide rail 5.

[0080] As can be seen from Figures 3, 7, and 8, the guide carriage 10 in this example has a base body 11 having a first surface region 25, which extends parallel to the first plane E1 along the first section UK1-1 of the roller circulation passage UK1. The rollers R1 of the first roller row RR1 contact the first surface region 25 of the base body 11 at the end face of each roller R1 away from the section TS1 of the separation web TS in the first section UK1-1 of the roller circulation passage UK1, and are guided by the first surface region 25 of the base body 11 when the guide carriage 10 moves in the longitudinal direction of the profile guide rail 5.

[0081] Correspondingly, the guide carriage 10 in this example has a base body 11 having a first surface area 25, which is configured to extend parallel to the first plane E2 along the first section UK2-1 of the roller circulation passage UK2, and the rollers R1 of the first roller row RR1 contact the first surface area 25 of the base body 11 at the end face of each roller R1 away from the section TS1 of the separation web TS in the first section UK2-1 of the roller circulation passage UK2, and are guided by the first surface area 25 of the base body 11 when the guide carriage 10 moves in the longitudinal direction of the profile guide rail 5.

[0082] As suggested by Figures 8 and 9, each of the rollers R1 and R2 is formed rotationally symmetric with respect to its longitudinal axis, and each roller is configured to have a diameter that varies in the direction of its longitudinal axis, so that the diameters of the rollers R1 and R2 have a maximum value Dmax in the central region ME between the opposite end faces SF1 and SF2 of the rollers, and the diameter D decreases continuously and gradually in the direction of the longitudinal axis of the roller, depending on the distance DX from the central region ME, starting from the central region ME between the opposite end faces SF1 and SF2.

[0083] Furthermore, section TS-1 of the separation web TS extends parallel to the first plane E1 in the first section UK1-1 of the roller circulation passage UK1 of the roller deflector UV1, and it can be seen that the separation web has a height smaller than the maximum diameter Dmax of the rollers R1 and R2 with respect to the roller track surface 20 of the base body 11 that defines the first section UK1-1 of the roller circulation passage UK1 of the roller deflector UV1.

[0084] Furthermore, section TS-1 of the separation web TS extends parallel to the first plane E2 in the first section UK2-1 of the roller circulation passage UK2 of the roller deflector UV2, and the separation web has a height smaller than the maximum diameter Dmax of the rollers R1,R2 with respect to the roller track surface 21 of the base body 11 that defines the first section UK2-1 of the roller circulation passage UK2 of the roller deflector UV2.

[0085] Furthermore, Figure 8 suggests that section TS-1 of the separation web TS extends parallel to the first planes E1, E2 such that, in the first sections UK1-1, UK2-1 of the roller circulation passages UK1-1, UK2-1 of the roller deflectors UV1, UV2, the separation web has an end section TSE that is separated from one of the roller track surfaces 20, 21 of the base body 11 that defines the first sections UK1-1, UK2-1 of the roller circulation passages UK1-1, UK2-1 of the base body 11.

[0086] Section TS-1 of the separation web TS has a first projection V1 at a distant end section TSE, which extends perpendicular to the first planes E1, E2 such that it extends over the roller R1 of the first roller row RR1 adjacent to the first side surface F1 of the separation web TS in the regions MSF1, MSF2 of the circumferential surface MF of the roller R1 adjacent to the first side surface F1 of the separation web TS (Figures 8 and 9). Section TS-1 of the separation web TS further has a second projection V2 at a distant end section TSE. This second projection V2 extends perpendicular to the first planes E1, E2 such that it extends over the roller R2 of the second roller row RR2 adjacent to the second side surface F2 of the separation web TS in the regions MSF1, MSF2 of the circumferential surface MF of the roller R2 adjacent to the second side surface F2 of the separation web TS (Figures 8 and 9).

[0087] As suggested by Figures 7 to 9, the roller deflection devices UV1 and UV2 may include strips 60 extending in the longitudinal direction of the profile guide rail 5, which are positioned near the surface area 25 of the base body 11 such that the strips 60 are adjacent to the end face of the roller R1, away from the separation web TS. The strips 60 have projections V1 which extend beyond the area of ​​the circumferential surface MF of the roller R1 adjacent to the strips 60.

[0088] Furthermore, the roller deflection devices UV1 and UV2 may include strips 61 extending in the longitudinal direction of the shaped material guide rail 5, the strips 61 being positioned adjacent to the end face of the roller R2, away from the separation web TS. The strips 61 have projections V2, which extend beyond the area of ​​the side surface MF of the roller R1 adjacent to the strips 61.

[0089] Figure 8 suggests that the separation web TS has a first groove N1 on its first side surface F1 that extends along the roller circulation passages UK1 and UK2, and that a lubricant for lubricating the rollers R1 of the first roller row RR1 can be introduced into the roller circulation passages UK1 and UK2 through this first groove N1. Correspondingly, the separation web TS has a second groove N2 on its second side surface F2 that extends along the roller circulation passages UK1 and UK2, and that a lubricant for lubricating the rollers R2 of the second roller row RR2 can be introduced into the roller circulation passages UK1 and UK2 through this second groove N2.

[0090] The lubricant to be transported through groove N1 or N2 can be supplied to groove N1 or N2 via an inlet opening 13 formed in the end cap 12 (through a connecting pipeline not shown).
