Description

Technical Field

[0001] This invention relates to a linear roller profile guide, specifically to a linear roller profile guide with a profile guide, comprising at least four flat roller running track surfaces extending along the longitudinal direction of the profile guide; the linear roller profile guide further comprises a guide carriage capable of linearly moving along the longitudinal direction of the profile guide, the guide carriage comprising a body on which at least four flat roller running track surfaces extending along the longitudinal direction of the profile guide are formed. Background Technology

[0002] The above-mentioned types of linear roller profile guides have a wide range of applications, including for precise and rapid positioning of items.

[0003] The guide carriage is mounted on the profile guide rail by rollers. To achieve linear movement of the guide carriage in the longitudinal direction of the guide rail, the guide carriage is provided with multiple (at least four) roller deflection devices. Each roller deflection device includes a roller circulation channel extending in an annular shape, which defines a closed annular roller track. Typically, a row of rollers is arranged in the roller circulation channel so that when the guide carriage moves along the longitudinal direction of the profile guide rail, the rollers in the corresponding roller row pass through the roller circulation channel sequentially, thereby causing the rollers to circulate along the closed annular track of the corresponding roller deflection device.

[0004] During the linear movement of the guide carriage along the longitudinal direction of the profile guide rail, the rollers circulate through different sections of the roller circulation channel, where they bear different levels of mechanical load. For example, the rollers of the roller deflector sequentially pass through the first section of the circulation channel, which is defined by one of the roller running tracks of the profile guide rail and one of the roller running tracks of the main body, wherein the roller running track of the main body extends (substantially) parallel to the roller running track of the profile guide rail. The rollers currently located in this first section of the roller circulation channel bear a greater mechanical load because the roller diameter is selected such that the rollers are clamped between the roller running track of the profile guide rail and the roller running track of the main body defining the first section of the roller circulation channel, and are therefore under mechanical stress. The first section of the roller circulation channel is therefore also referred to as the "load zone" or "bearing zone" of the roller circulation channel. On the other hand, the rollers currently circulating outside the first section of the roller circulation channel are not subjected to mechanical loads. Therefore, the area outside the "load zone" in the roller circulation channel is called the "no-load zone".

[0005] The linear roller profile guides of the above type are characterized by their suitability for applications where the guide carriage needs to withstand high horizontal loads perpendicular to the longitudinal axis of the profile guide. Furthermore, the at least four roller deflection devices can be arranged relative to each other such that the guide carriage can withstand high horizontal loads in any direction perpendicular to the longitudinal axis of the profile guide.

[0006] When the guide carriage moves along the longitudinal direction of the profile guide rail, the aforementioned linear roller profile guide rail typically exhibits what is known as "stroke pulsation" of the guide carriage. "Stroke pulsation" refers to the slight upward and downward movement of the guide carriage in the longitudinal direction perpendicular to the guide rail. This micro-movement occurs periodically as the guide carriage travels the distance on the guide rail. The main reason for this stroke pulsation is that the guide carriage is currently supported on the guide rail only by the rollers currently located in the load area of ​​the roller circulation channel of the corresponding roller deflection device of the guide carriage, and the rollers in the load area of ​​the corresponding circulation channel are typically always subjected to mechanical preload. Due to this mechanical preload, localized elastic deformation occurs in the body of the guide carriage and the guide rail near the rollers in the load area of ​​the corresponding roller circulation channel. As the guide carriage moves longitudinally along the guide rail, the rollers circulate in the roller circulation channels of the corresponding roller deflection devices. This causes one row of rollers to sequentially pass through the load area of ​​the roller circulation channel in one direction. Thus, at one end of the load area, each roller continuously enters the load area from the unloaded area of ​​the roller circulation channel; while at the other end, each roller continuously leaves the load area to re-enter the unloaded area of ​​the roller circulation channel. Therefore, as the guide carriage moves longitudinally along the guide rail, the number of rollers currently located in the load area of ​​one of the roller circulation channels is not constant, but changes periodically with the distance the guide carriage travels. This change in the number of rollers currently located in the load area of ​​the roller circulation channel results in periodic changes in the local elastic deformation of the guide carriage body and the guide rail near the load area of ​​the roller circulation channel as the guide carriage moves longitudinally along the guide rail. The periodic elastic deformation of the body of the guide carriage and the guide rail ultimately results in a measurable periodic lifting and lowering movement (“stroke pulsation”) at any point on the guide carriage as it moves along the longitudinal direction of the guide rail.

[0007] The stroke pulsation of the guide carriage in traditional roller profile guides has an amplitude of approximately 1-2 μm. This amplitude of stroke pulsation limits the positioning accuracy of roller profile guides, thus affecting their applicability in many applications, such as positioning tools used for high-precision machining of workpiece surfaces, like obtaining a smooth, flat surface by grinding parts for low-noise gearboxes in electric vehicles. Therefore, there is an urgent need to significantly reduce stroke pulsation.

[0008] With a fixed roller size in a roller profile guide, a simple approach to reduce stroke pulsation amplitude is to increase the length of the guide carriage and the load zone of the roller circulation channel, thereby increasing the number of rollers simultaneously within the load zone of the roller circulation channel. However, this approach has limitations: in many cases, the space requirements for the arrangement of the guide carriage must be considered, which may prevent the selection of a longer guide carriage.

[0009] If it is not possible or desired to increase the length of the guide carriage (or the length of the load area of ​​the roller circulation channel), another approach to reduce stroke pulsation is to design a corresponding roller deflection device, arranging multiple roller rows (such as two rows) side by side in the roller circulation channel of the roller deflection device, so that when the guide carriage moves along the longitudinal direction of the guide rail, the multiple roller rows (such as two rows) can pass through the roller circulation channel side by side, and correspondingly pass through the load area of ​​the roller circulation channel side by side together.

[0010] For example, DE112012003767 B4 discloses a roller profile guide rail, wherein the four roller running track surfaces of the guide rail and the four roller running track surfaces of the guide carriage all include an arc-shaped profile in a cross-section perpendicular to the longitudinal direction of the guide rail. One embodiment of this roller profile guide rail includes four roller deflection devices, in which two rows of rollers are arranged side-by-side and circulate side-by-side through a roller circulation channel. The rollers in the side-by-side roller rows are connected to each other by a synthetic resin belt, such that the rollers in one roller row are connected to the rollers in the other roller row via the belt. The belt needs to align the rotation axes of the two rows of side-by-side rollers in different sections of the roller circulation channel. Furthermore, the belt also maintains a certain distance between adjacent rollers in each of the two roller rows. The drawback of this profile roller deflection device is that the belt structure is relatively complex and prone to wear.

[0011] JPH06300039(A) discloses a roller profile guide rail, comprising a guide rail having four flat roller running track surfaces and a guide carriage having four flat roller running track surfaces. The roller profile guide rail includes four roller deflection devices, wherein in each roller deflection device, two rows of rollers are arranged side-by-side and can circulate side-by-side through a roller circulation channel. In this embodiment, each roller deflection device is designed as a "full-complement" roller deflection device, that is, the rollers arranged in the roller circulation channel of the roller deflection device are not connected to each other by belts or chains, and no technical means are used to separate two consecutive rollers in each roller row or to maintain a certain distance between them. Therefore, when the rollers circulate in the circulation channel, the outer circumferential surfaces of adjacent rollers are in direct contact with each other. The two roller rows are arranged side-by-side in the roller circulation channel such that two adjacent rollers contact each other at their opposing front end faces. The drawback is that rollers arranged adjacent to each other may interfere with each other and, for example, block each other as they circulate through the roller circulation channel. This accelerates roller wear and shortens their service life.

[0012] US2015 / 0159695A1 discloses a linear roller profile guide rail, comprising a linear profile guide rail and a guide carriage. The roller profile guide rail has four roller circulation channels, each containing two rows of rollers arranged side-by-side. When the guide carriage moves along the longitudinal direction of the profile guide rail, the rollers in the two rows circulate side-by-side parallel to the plane passing through the corresponding circulation channel. Each roller circulation channel contains multiple separators, wherein individual separators are arranged one after another in a row within the corresponding roller circulation channel. Each separator is disposed between the rollers located within the roller circulation channel, such that a single separator is capable of: separating or maintaining a certain distance between at least two consecutive rollers in one of two roller rows arranged in the respective roller circulation channel; separating or maintaining a certain distance between at least two consecutive rollers in the other of two roller rows arranged in the respective roller circulation channel; and separating one roller in each of the two roller rows arranged in the respective roller circulation channel from at least two rollers in the other of the two roller rows arranged in the respective roller circulation channel. Each individual separator is connected to at least two consecutive rollers in one row of two roller rows arranged in the corresponding roller circulation channel and to at least two consecutive rollers in the other row of two roller rows arranged in the corresponding roller circulation channel, such that when the guide carriage moves longitudinally along the profile guide rail, all separators move together synchronously with the rollers in the corresponding roller circulation channel; and the rollers in one row of two roller rows arranged in the corresponding roller circulation channel can only move synchronously with the rollers in the other row of two roller rows arranged in the corresponding roller circulation channel. Each individual separator is configured to include several distinct portions: a separator wall disposed between two rows of rollers such that the separator wall slides in contact with the leading edge faces of rollers in one row of the two roller rows disposed in the corresponding roller circulation channel and with the leading edge faces of two rollers in the other row of the two roller rows disposed in the corresponding roller circulation channel; a first separator comprising two side arms connected to the separator wall and extending from a first side of the separator wall, such that the two side arms surround the outer circumferential surface portion of rollers in one row of the two roller rows disposed in the corresponding roller circulation channel; and a second separator extending from a second side of the separator wall (opposite to the first separator), such that the second separator extends between two consecutive rollers in the other row of the two roller rows disposed in the corresponding roller circulation channel and separates them from each other. In this roller profile guide, the separator wall of the separator is connected to the first separator and the second separator. Because the respective separator has a first separator and a second separator, the roller deflection device of this roller profile guide is not a "full-scale" roller deflection device.The disadvantage of this is that the presence of the corresponding separators reduces the maximum load-bearing capacity of the roller profile guide. Furthermore, the implementation of the numerous separators in the roller circulation channel and the combination of a large number of rollers arranged in two rows is cumbersome and time-consuming. Summary of the Invention

[0013] The purpose of this invention is to overcome the above-mentioned defects and provide a linear roller profile guide rail with a fully configured roller deflection device, wherein the roller deflection device is applicable to multiple roller rows arranged side by side, can better guide the roller rows arranged side by side, and reduce roller wear.

[0014] This objective is achieved by a linear roller profile guide having the features described in claim 1.

[0015] The linear roller profile guide rail includes a profile guide rail and a guide carriage, wherein the profile guide rail has at least four flat roller running track surfaces extending along the longitudinal direction of the profile guide rail; the guide carriage is configured to be linearly movable along the longitudinal direction of the profile guide rail and includes a body on which at least four flat roller running track surfaces extending along the longitudinal direction of the profile guide rail are formed.

[0016] The roller running track surface of the profile guide rail and the roller running track surface of the main body are arranged opposite to each other, such that one of the roller running track surfaces of the profile guide rail and one of the roller running track surfaces of the main body extend parallel to each other and are arranged opposite to each other at a certain distance, so that one of the roller running track surfaces of the profile guide rail and the corresponding roller running track surface of the main body jointly define a bearing roller channel.

[0017] Corresponding to each load-bearing roller channel, the guide carriage includes a full-configuration roller deflector for multiple side-by-side roller rows, each roller deflector corresponding to a specific load-bearing roller channel. The roller deflector is attached to the body and includes a roller circulation channel extending in an annular manner, defining a closed annular roller track for the multiple side-by-side roller rows. The roller circulation channel of the roller deflector includes: a first section of the roller circulation channel coinciding with the corresponding load-bearing roller channel; a second section of the roller circulation channel extending at a certain distance from the first section in the longitudinal direction of the profile guide; a third and a fourth section of the roller circulation channel, wherein the third section connects one end of the two opposite ends of the first section to one end of the two opposite ends of the second section; and the fourth section connects the other end of the first section to the other end of the second section.

[0018] The roller deflection device corresponding to the corresponding bearing roller channel includes at least a first row of rollers and a second row of rollers. The first row of rollers and the second row of rollers each include a plurality of rollers arranged continuously (one after another). The first row of rollers and the second row of rollers are arranged side by side in the circulation channel of the roller deflection device, so that when the guide carriage moves along the longitudinal direction of the profile guide rail, the rollers in the first row of rollers and the rollers in the second row of rollers pass through the roller circulation channel side by side in parallel with a preset first plane along the annular closed track.

[0019] According to the present invention, a full-load configuration roller deflection device corresponding to a corresponding bearing roller channel includes a partition web fixed relative to the main body and extending parallel to the first plane through a first, second, third, and fourth section of the roller circulation channel, and disposed between the first and second rows of rollers, such that the partition web spatially separates the rollers in the first row from the rollers in the second row. Each roller in the first row abuts against a first side surface of the partition web with its corresponding front end face, such that when the guide carriage moves in the longitudinal direction of the profile guide rail, each roller in the first row abuts against the first side surface of the partition web. Furthermore, each roller in the second row abuts against a second side surface of the partition web with its corresponding front end face, such that when the guide carriage moves in the longitudinal direction of the profile guide rail, each roller in the second row is guided on the second side surface of the partition web.

[0020] Accordingly, a partition web is provided in the roller circulation channel of each roller deflector to separate at least two rows of rollers arranged in the roller circulation channel of the roller deflector. Therefore, the rollers in the first row and the rollers in the second row can circulate side-by-side with each other parallel to the first plane within the roller circulation channel, without the front ends of the rollers in the first row and the rollers in the second row contacting each other. Since the partition web of the corresponding roller deflector is fixed relative to the main body, when the guide carriage moves along the longitudinal direction of the profile guide rail, it is ensured that the rollers in the first row and the rollers in the second row circulate side-by-side with each other along the annular closed track, thereby allowing each roller in the first row and each roller in the second row to circulate relative to the partition web along the annular closed roller track (especially relative to the partition web along the entire extension of the partition web in the longitudinal direction of the roller circulation channel). Compared to the roller profile guide disclosed in JPH06300039(A), the partition web reduces roller wear. Furthermore, the partition web serves as a lateral guide surface for the leading edge face of at least one row of rollers in a multi-row configuration. This improves guide stability.

[0021] In one embodiment of the linear roller profile guide, the partition web within the roller circulation channel of the roller deflection device is configured such that it extends seamlessly along the entire length of the roller circulation channel along a closed annular track of a plurality of rollers arranged side-by-side. When the guide carriage moves along the partition web in the longitudinal direction of the profile guide along the entire length of the roller circulation channel in that direction, each roller in the first row can move relative to the partition web, such that the corresponding roller abuts its front end face against a first side surface of the partition web. Correspondingly, when the guide carriage moves along the partition web in the longitudinal direction of the profile guide along the entire length of the roller circulation channel in that direction, each roller in the second row can move relative to the partition web, such that the rollers in the second row are guided respectively on a second side surface of the partition web. This allows all rollers to be guided with exceptionally high stability along the entire length of the closed annular track of the rollers by the same partition web.

[0022] In one embodiment of the linear roller profile guide, the body includes a first surface region extending parallel to the first plane along a first segment of the roller circulation channel, such that rollers in a first row of rollers within the first segment of the roller circulation channel abut against the first surface region of the body with their respective front end faces away from the separating web, and the first surface region of the body is guided as the guide carriage moves in the longitudinal direction of the profile guide.

[0023] In this embodiment, the first surface region of the body ensures that the rollers in the first row of rollers located within the first section of the roller circulation channel, i.e., within the load area of ​​the roller circulation channel, can be laterally guided with high stability in the first surface region of the body. Since the rollers in the first row are positioned with their front ends against the partition web, the lateral guidance of the first row of rollers in the first surface region of the body also indirectly stabilizes the spatial position of the partition web, thereby allowing the second row of rollers to be guided on the partition web with even better stability.

[0024] In another embodiment of the linear roller profile guide, the roller deflection device includes multiple independent components, and the partition web includes multiple segments, wherein: One of the independent components includes a section of the separating web that extends across at least a portion of the length of the first section of the roller circulation channel; and / or One of the independent components includes a section of the separating web that extends across at least a portion of the length of the second section of the roller circulation channel; and / or One of the independent components includes a section of the separating web that extends across at least a portion of the length of the third section of the roller circulation channel; and / or One of the separate components includes a section of the partition web that extends across at least a portion of the length of the fourth section of the roller circulation channel.

[0025] In this way, the process of setting the dividing web along the entire length of the roller circulation channel is simplified. For example, different sections of the dividing web corresponding to different segments of the roller circulation channel can be made of different materials. For example, the components of the roller deflection device and the sections of the dividing web can be made of plastic and manufactured economically and efficiently by, for example, injection molding.

[0026] In one embodiment of the linear roller profile guide, each roller is rotationally symmetrical with respect to its longitudinal axis, and the diameter of each roller relative to its longitudinal axis varies in the longitudinal axial direction, such that the diameter of the roller includes a maximum value within an intermediate region between the opposing front faces of the roller; and, starting from the intermediate region between the opposing front faces, along the longitudinal axial direction of the roller, the diameter continuously decreases as the distance from the intermediate region increases, being a function of the distance from the intermediate region. Furthermore, a partition web within the first segment of the roller circulation channel of the roller deflection device extends parallel to the first plane, such that the partition web has a height less than the maximum value of the roller diameter relative to one of the roller running track surfaces of the body defining the first segment of the roller circulation channel of the roller deflection device.

[0027] In this way, the partition web located within the bearing area of ​​the roller circulation channel can completely abut against the front faces of the rollers in the first row and the rollers in the second row on the entire surface of the corresponding front face, without the partition web coming into contact with the roller running track surface formed on the profile track.

[0028] In another embodiment of the linear roller profile guide, the partition web extends parallel to the first plane in the first segment of the roller circulation channel of the roller deflection device relative to the roller running track surface of the body defining the first segment of the roller circulation channel of the roller deflection device, such that the partition web includes end segments spaced apart from the roller running track surface of the body. In this case, the partition web includes a first protrusion in the spaced end segments, the first protrusion extending perpendicular to the first plane, such that the first protrusion is internally suspended above the rollers of the first row of rollers abutting against the first side of the partition web in the outer circumferential surface region of the rollers abutting against the first side of the partition web. Furthermore, the partition web includes a second protrusion in the spaced end segments, the second protrusion extending perpendicular to the first plane, such that the second protrusion is internally suspended above the rollers of the second row of rollers abutting against the second side of the partition web in the outer circumferential surface region of the rollers abutting against the second side of the partition web.

[0029] The effect of providing a first protrusion in the spaced-apart end section of the partition web is that when the guide carriage is removed from the profile guide rail, the rollers in the first row of rollers located in the bearing area of ​​the roller circulation channel can be held on the guide carriage by the first protrusion.

[0030] Accordingly, the effect of providing a second protrusion in the spaced-apart end section of the partition web is that when the guide carriage is removed from the profile guide rail, the rollers in the second row of rollers located in the bearing area of ​​the roller circulation channel can be held on the guide carriage by the second protrusion.

[0031] In another embodiment of the linear roller profile guide, the partition web includes a first groove extending along the roller track (or along the roller circulation channel) on a first side of the partition web, through which lubricant for lubricating the rollers in the first row of rollers can be introduced into the roller circulation channel; and / or the partition web includes a second groove extending along the roller track (or along the roller circulation channel) on a second side of the partition web, through which lubricant for lubricating the rollers in the second row of rollers can be introduced into the roller circulation channel.

[0032] The first groove allows lubricant (such as lubricating oil or grease) to be distributed along the roller circulation channel to lubricate the first row of rollers. Correspondingly, the second groove allows lubricant (such as lubricating oil or grease) to be distributed along the roller circulation channel to lubricate the second row of rollers.

[0033] In another embodiment of the linear roller profile guide, the separator is made of plastic; or, at least a portion of the separator web is made of plastic.

[0034] Plastics that are particularly suitable are those that can ensure high rigidity and low coefficient of friction, such as polyoxymethylene (also known as POM or polyacetal).

[0035] Alternatively, the portion of the separating web extending in the first section of the roller circulation channel may be made of a metallic material, such as steel. Attached Figure Description

[0037] Unless otherwise stated, the same elements in the figures are referred to by the same reference numerals.

[0038] Figure 1 A perspective view of the linear roller profile guide 1 of the present invention is shown, which includes a profile guide 5 and a guide carriage 10 mounted on the profile guide 5.

[0039] In this embodiment, the profile guide rail 5 includes four flat roller running track surfaces 6 and 7 extending along the longitudinal direction of the profile guide rail 5. These roller running track surfaces are spatially distributed on opposite sides 5.1 and 5.2 of the profile guide rail 5: from Figure 1 As can be seen, on each side 5.1 or 5.2 of the profile guide rail 5, a roller running track surface 6 and a roller running track surface 7 are formed. On each side 5.1 or 5.2, the corresponding running track surface 6 and the corresponding roller running track surface 7 are arranged adjacent to each other and extend parallel to the roller running track surface 7 along the longitudinal direction of the profile guide rail 5.

[0040] Referring to a cross section perpendicular to the profile guide rail 5, roller running track surfaces 6 and 7 formed on the side surface 5.1 are arranged relative to each other such that the roller running track 6 is perpendicular to the roller running track surface 7 in a cross section perpendicular to the profile guide rail 5 (in combination). Figure 1 and Figure 2 (It can be seen that...)

[0041] Accordingly, the roller running track surfaces 6 and 7 formed on the side surface 5.2 are arranged relative to each other such that the roller running track surface 6 extends perpendicularly to the roller running track surface 7 in a section perpendicular to the profile guide rail 5 (in combination). Figure 1 and Figure 2 visible).

[0042] The guide carriage 10 is mounted on the profile guide rail 5, thereby enabling the guide carriage 10 to move linearly along the longitudinal direction of the profile guide rail 5. Figure 1 As shown, the guide carriage 10 mainly includes a main body 11 and two end caps 12. The end caps 12 are installed on the opposite front end surfaces of the main body 11 along the longitudinal direction of the profile guide rail 5.

[0043] like Figure 1 and Figure 5 As shown, each end cap 12 includes multiple inlets 13 for supplying lubricant to the rollers of the roller profile guide 1. (See the following text in conjunction with...) Figure 8 As described in detail, the lubricant injected through inlet 13 can be transferred from end cap 12 to the rollers of the roller profile guide rail 1 inside the guide carriage 10.

[0044] The following is combined with Figure 2-9 A more detailed description of the roller profile guide rail 1 is provided below.

[0045] like Figure 2 and Figure 3 As shown, the main body 11 of the guide carriage 10 includes a U-shaped profile with two side arms 11.1 and 11.2 in a cross section perpendicular to the longitudinal direction of the profile guide rail 5.

[0046] The cross-sectional profile of the main body 11 is designed such that when the guide carriage 10 of the profile guide rail 5 is as follows: Figure 1 When installed as shown, the upper part of the profile guide rail 5, especially including the roller running track surfaces 6 and 7 formed on the side 5.1 of the profile guide rail 5 and the roller running track surfaces 6 and 7 formed on the side 5.2 of the profile guide rail 5, is located in the intermediate space between the side arms 11.1 and 11.2 of the U-shaped profile of the main body 11.

[0047] The cross-sectional profile of the main body 11 is designed such that a first gap extending along the longitudinal direction of the profile guide rail 5 is formed between the side arm 11.1 of the main body 11 and the side surface 5.1 of the profile guide rail 5. Correspondingly, a second gap extending along the longitudinal direction of the profile guide rail 5 is formed between the side arm 11.2 of the main body 11 and the side surface 5.2 of the profile guide rail 5. The first gap located between the side arm 11.1 of the main body 11 and the side surface 5.1 of the profile guide rail 5, and the second gap located between the side arm 11.2 of the main body 11 and the side surface 5.2 of the profile guide rail 5, are used to accommodate the rollers of the roller profile guide rail 1. The guide carriage 10 is supported on the roller running track surfaces 6 and 7 of the profile guide rail 5 by these rollers so that the guide carriage 10 can move along the longitudinal direction of the profile guide rail 5.

[0048] like Figure 2 As shown, the structure of the roller profile guide rail 1 is such that the guide carriage 10 and the profile guide rail 5 are symmetrically formed to form... Figure 2 The symmetry plane SE shown (the symmetry plane SE along) Figure 2 The dashed line shown extends and is labeled with reference numeral SE along the longitudinal direction of the profile guide rail 5.

[0049] like Figure 2 As shown, on the side arm 11.1 of the main body 11 (on the side of the side arm 11.1 opposite to the side 5.1 of the profile guide rail 5), two flat roller running track surfaces 20 and 21 extending along the longitudinal direction of the profile guide rail are formed.

[0050] In a cross section perpendicular to the profile guide rail 5, roller running track surfaces 20 and 21 formed on the side arm 11.1 of the main body 11 are arranged adjacent to each other, such that the roller running track surface 20 extends perpendicular to the roller running track surface 21 in a cross section perpendicular to the profile guide rail 5.

[0051] like Figure 2 As shown, on the side arm 11.2 of the main body 11 (on the side of the side arm 11.2 opposite to the side 5.2 of the profile guide rail 5), two flat roller running track surfaces 20 and 21 extending along the longitudinal direction of the profile guide rail are formed.

[0052] In a cross section perpendicular to the profile guide rail 5, roller running track surfaces 20 and 21 formed on the side arm 11.2 of the main body 11 are arranged adjacent to each other, such that the roller running track surface 20 extends perpendicular to the roller running track surface 21 in a cross section perpendicular to the profile guide rail 5.

[0053] like Figure 2 As shown, the roller running track surfaces 20 and 21 formed on the side arm 11.1 of the main body 11 are arranged relative to each other with the roller running track surfaces 6 and 7 formed on the side surface 5.1 of the profile guide rail 5. The roller running track surface 6 formed on the side 5.1 of the profile guide rail 5 and the roller running track surface 20 formed on the side arm 11.1 of the main body 11 extend parallel to each other and are arranged at a certain distance from each other, so that the roller running track surface 6 formed on the side 5.1 of the profile guide rail 5 and the roller running track surface 20 formed on the side arm 11.1 of the main body 11 together define the bearing roller channel LK1; and The roller running track surface 7 formed on the side 5.1 of the profile guide rail 5 and the roller running track surface 21 formed on the side arm 11.1 of the main body 11 extend parallel to each other and are arranged at a certain distance from each other, so that the roller running track surface 7 formed on the side 5.1 of the profile guide rail 5 and the roller running track surface 21 formed on the side arm 11.1 of the main body 11 together define the bearing roller channel LK2.

[0054] like Figure 2 As shown, the roller running track surfaces 20 and 21 formed on the side arm 11.2 of the main body 11 are arranged relative to each other with the roller running track surfaces 6 and 7 formed on the side surface 5.2 of the profile guide rail 5. The roller running track surface 6 formed on the side 5.2 of the profile guide rail 5 and the roller running track surface 20 formed on the side arm 11.2 of the main body 11 extend parallel to each other and are arranged at a certain distance from each other, so that the roller running track surface 6 formed on the side 5.2 of the profile guide rail 5 and the roller running track surface 20 formed on the side arm 11.2 of the main body 11 together define the bearing roller channel LK1; and The roller running track surface 7 formed on the side 5.2 of the profile guide rail 5 and the roller running track surface 21 formed on the side arm 11.2 of the main body 11 extend parallel to each other and are arranged at a certain distance from each other, so that the roller running track surface 7 formed on the side 5.2 of the profile guide rail 5 and the roller running track surface 21 formed on the side arm 11.2 of the main body 11 together define the bearing roller channel LK2.

[0055] like Figure 2 As shown, two adjacent through holes 30 and 31 are formed on the side arm 11.1 of the main body 11, and each through hole extends along the longitudinal direction of the profile guide rail 5.

[0056] Correspondingly, two adjacent through holes 30 and 31 are also formed on the side arm 11.2 of the main body 11, and each through hole extends along the longitudinal direction of the profile guide rail 5.

[0057] like Figure 2-4As shown, for each of the two carrying roller channels LK1, the guide carriage 10 includes a fully configured roller deflector UV1, which is assigned to a corresponding carrying roller channel LK1 for two roller rows RR1 and RR2 arranged adjacent to each other. The roller deflector UV1 is attached to the body 11 and includes a roller circulation channel UK1 extending in an annular manner, which defines an annular closed track for the roller rows RR1 and RR2 arranged side-by-side. Figures 2-4 In the rollers located in the circulation channel UK1 of the roller deflection device UV1, rollers belonging to roller row RR1 are all marked as R1, while rollers belonging to roller row RR2 are all marked as R2.

[0058] The deflection device UV1 is a "full-capacity configuration," meaning that no technical means are used to maintain a certain distance between two adjacent rollers R1 in the roller row RR1. Instead, the outer surfaces of the two adjacent rollers R1 contact each other through the circulation of the rollers R1 in the roller circulation channel UK1 (e.g., Figure 4 and Figure 6 (As shown). Accordingly, no technical means are used to maintain a certain distance between two adjacent rollers R2 in the roller bank RR2. Instead, the rollers R2 can circulate in the roller circulation channel UK1 so that the outer circular surfaces of two adjacent rollers R2 are in contact with each other (as shown). Figure 4 and Figure 6 (As shown).

[0059] like Figures 2-4 As shown, for each of the two carrying roller channels LK2, the guide carriage 10 includes a fully configured roller deflector UV2, which is assigned to a corresponding carrying roller channel LK2 for two adjacent roller rows RR1 and RR2. The roller deflector UV2 is attached to the body 11 and includes a roller circulation channel UK2 extending in an annular manner, defining an annular closed track for the two roller rows RR1 and RR2 arranged side-by-side. Figures 2-4 In the process, for the rollers located in the circulation channel UK2 of the roller deflection device UV2, the rollers belonging to roller row RR1 are all marked as R1, while the rollers belonging to roller row RR2 are all marked as R2.

[0060] The deflection device UV2 is a "full-capacity configuration," meaning that no technical means are used to maintain a certain distance between two adjacent rollers R1 in the roller row RR1. Instead, the outer surfaces of the two adjacent rollers R1 come into contact with each other through the circulation of the rollers R1 in the roller circulation channel UK2 (e.g., ...). Figure 6 (As shown). Accordingly, no technical means are used to maintain a certain distance between two adjacent rollers R2 in the roller bank RR2. Instead, the outer surfaces of the two adjacent rollers R2 come into contact with each other through the circulation of the rollers R2 in the roller circulation channel UK2 (as shown). Figure 6 (As shown).

[0061] like Figures 2-4 As shown, the roller circulation channel UK1 of each roller deflection device UV1 includes: The first segment UK1-1 of the roller circulation channel UK1 coincides with the corresponding single load-bearing roller channel LK1; The second segment UK1-2 of the roller circulation channel UK1 extends through one of the through holes 30 of the main body 11 at a certain distance from the first segment UK1-1 of the roller circulation channel UK1 in the longitudinal direction of the profile guide rail 5. The third segment UK1-3 and the fourth segment UK1-4 of the roller circulation channel UK1, wherein the third segment UK1-3 connects one end of the two opposite ends of the first segment UK1-1 of the roller circulation channel UK1 to one end of the two opposite ends of the second segment UK1-2 of the roller circulation channel UK1; and the fourth segment UK1-4 connects the other end of the two opposite ends of the first segment UK1-1 of the roller circulation channel UK1 to the other end of the two opposite ends of the second segment UK1-2 of the roller circulation channel UK1.

The third segment UK2-3 and the fourth segment UK2-4 of the roller circulation channel UK2, wherein the third segment UK2-3 connects one end of the two opposite ends of the first segment UK2-1 of the roller circulation channel UK2 to one end of the two opposite ends of the second segment UK2-2 of the roller circulation channel UK2; and the fourth segment UK2-4 connects the other end of the two opposite ends of the first segment UK2-1 of the roller circulation channel UK2 to the other end of the two opposite ends of the second segment UK2-2 of the roller circulation channel UK2.

[0063] like Figures 2-4 As shown, each roller deflection device UV1 (assigned to one of the roller carrying channels LK1) includes at least a first roller row RR1 and a second roller row RR2, wherein the first roller row RR1 includes a plurality of rollers R1 arranged sequentially one after another, and the second roller row RR2 correspondingly includes a plurality of rollers R2 arranged sequentially one after another; and the first roller row RR1 and the second roller row RR2 are arranged side by side relative to each other in the roller circulation channel UK1 of the roller deflection device UV1, so that when the guide carriage 10 moves in the longitudinal direction of the profile guide rail 5, the rollers R1 in the first roller row RR1 and the rollers R2 in the second roller row RR2 circulate side by side with each other along the annular closed track parallel to the preset first plane E1 through the roller circulation channel UK1 (e.g. Figure 3 (As shown).

[0064] like Figures 2-4 As shown, each roller deflection device UV2 (assigned to one of the roller carrying channels LK2) includes at least a first roller row RR1 and a second roller row RR2, wherein the first roller row RR1 includes a plurality of rollers R1 arranged sequentially one after another, and the second roller row RR2 correspondingly includes a plurality of rollers R2 arranged sequentially one after another; and the first roller row RR1 and the second roller row RR2 are arranged side by side relative to each other in the roller circulation channel UK2 of the roller deflection device UV2, such that when the guide carriage 10 moves in the longitudinal direction of the profile guide rail 5, the rollers R1 in the first roller row RR1 and the rollers R2 in the second roller row RR2 circulate side by side with each other along the annular closed track parallel to the preset first plane E2 through the roller circulation channel UK2 (e.g. Figure 3 (As shown).

[0065] like Figures 2-4As shown, both the roller deflection device UV1 and the roller deflection device UV2 are composed of a set of independent components. For example, a section of the roller deflection device UV1 formed on the side arm 11.1 or side arm 11.2 of the main body 11 extends through the through hole 30 on the side arm 11.1 or side arm 11.2 of the main body 11, while other sections of the roller deflection device UV1 formed on the side arm 11.1 or side arm 11.2 of the main body 11 extend along the roller running track surface 20 along the side arm 11.1 or side arm 11.2. For example, a section of the roller deflector UV2 formed on the side arm 11.1 or side arm 11.2 of the main body 11 extends through the through hole 31 on the side arm 11.1 or side arm 11.2 of the main body 11, while other sections of the roller deflector UV2 formed on the side arm 11.1 or side arm 11.2 of the main body 11 extend along the side arm 11.1 or side arm 11.2 along the roller running track surface 21.

[0066] To illustrate the spatial extension of the roller deflection devices UV1 and UV2 on the guide carriage 10, refer to Figure 5 . Figure 5 An exploded view of the roller profile guide rail 1 is shown. According to... Figure 5 It shows component 50, which includes all the components of roller deflection device UV1 to be arranged on the side arm 11.2 and all the components of roller deflection device UV2 to be arranged on the side arm 11.2 (separated from the side arm 11.2). Figure 5 Also shown is component 51, which includes all the components of roller deflection device UV1 to be arranged on the side arm 11.1 and all the components of roller deflection device UV2 to be arranged on the side arm 11.1 (separated from the side arm 11.1).

[0067] Figure 6 The arrangement of the first roller row RR1 and the second roller row RR2 in the roller deflection devices UV1 and UV2 is shown. Figure 6 It shows Figure 5 The structure of component 50 or 51 shown is not shown, but certain components forming the outer wall of the roller circulation channel UK1 or the outer wall of the roller circulation channel UK2 are not shown. Therefore, in Figure 6 In the 3D view, the arrangement of rollers R1 in the first roller row RR1 and rollers R2 in the second roller row RR2 can be seen.

[0068] like Figure 4 , Figure 5 , Figures 6-8As shown, the roller deflection device UV1 corresponding to each bearing roller channel LK1 includes a separating web TS. The separating web TS extends parallel to the first plane E1 in the roller circulation channel UK1 and passes through the first segment UK1-1, the second segment UK1-2, the third segment UK1-3 and the fourth segment UK1-4 of the roller circulation channel UK1, and is located between the first roller row RR1 and the second roller row RR2, so that the roller R1 in the first roller row RR1 and the roller R2 in the second roller row RR2 are spatially separated by the separating web TS.

[0069] The roller deflection device UV1 is attached to the main body 11 such that the partition web TS of the roller deflection device UV1 is fixed relative to the main body 11 (as shown in Figures 4-6).

[0070] Accordingly, the roller deflection device UV2 corresponding to each bearing roller channel LK2 includes a separating web TS, which extends parallel to the first plane E2 in the roller circulation channel UK2 and passes through the first segment UK2-1, the second segment UK2-2, the third segment UK2-3 and the fourth segment UK2-4 of the roller circulation channel UK2, and is located between the first roller row RR1 and the second roller row RR2, so that the roller R1 in the first roller row RR1 and the roller R2 in the second roller row RR2 are spatially separated by the separating web TS.

[0071] The roller deflection device UV2 is attached to the main body 11 such that the partition web TS of the roller deflection device UV2 is fixed relative to the main body 11 (as shown in Figures 4-6).

[0072] In this embodiment, the dividing web TS of the roller deflection device UV1 is preferably arranged in the roller circulation channel UK1 of the roller deflection device UV1 such that the dividing web TS extends seamlessly along the annular closed track of the roller rows RR1 or RR2 of the rollers R1 or R2 arranged side by side along the entire length of the roller circulation channel UK1.

[0073] The dividing web TS of the roller deflection device UV2 is preferably arranged in the roller circulation channel UK2 of the roller deflection device UV2 such that the dividing web TS extends seamlessly along the annular closed track of the roller rows RR1 or RR2 of the rollers R1 or R2 arranged side by side along the entire length of the roller circulation channel UK2.

[0074] like Figure 4 and Figure 6As shown, the dividing web TS of the roller deflection device UV1 includes multiple segments: for example, the dividing web TS of the deflection device UV1 has segments TS-1, TS-2, TS-3, and TS-4, wherein: segment TS-1 of the dividing web TS extends at least a portion of the length of the first segment UK1-1 of the roller circulation channel UK1; segment TS-2 of the dividing web TS extends at least a portion of the length of the second segment UK1-2 of the roller circulation channel UK1; segment TS-3 of the dividing web TS extends at least a portion of the length of the third segment UK1-3 of the roller circulation channel UK1; and / or segment TS-4 of the dividing web TS extends at least a portion of the length of the fourth segment UK1-4 of the roller circulation channel UK1.

[0075] Accordingly, the dividing web TS of the roller deflection device UV2 includes multiple segments: for example, the dividing web TS of the deflection device UV2 has segments TS-1, TS-2, TS-3, and TS-4, wherein: segment TS-1 of the dividing web TS extends at least a portion of the length of the first segment UK2-1 of the roller circulation channel UK2; segment TS-2 of the dividing web TS extends at least a portion of the length of the second segment UK2-2 of the roller circulation channel UK2; segment TS-3 of the dividing web TS extends at least a portion of the length of the third segment UK2-3 of the roller circulation channel UK2; and / or segment TS-4 of the dividing web TS extends at least a portion of the length of the fourth segment UK2-4 of the roller circulation channel UK2.

[0076] like Figure 4 , Figure 5 , Figures 6-8 As shown, it is clear that for each roller R1 in the first roller row RR1, the front end face of each roller R1 defines the first side face F1 of the partition web TS, so that when the guide carriage 10 moves along the longitudinal direction of the profile guide rail 5, each roller R1 in the first roller row RR1 always abuts against the first side face F1 of the partition web TS.

[0077] from Figure 4 , Figure 5 , Figures 6-8 It can also be seen that for each roller R2 in the second roller row RR2, the front end face of each roller R2 abuts against the second side surface F2 of the partition web TS, so that when the guide carriage 10 moves along the longitudinal direction of the profile guide rail 5, each roller R2 in the second roller row RR2 is guided by the second side surface F2 of the partition web TS.

[0078] like Figure 3 , Figure 7 and Figure 8As shown, the guide carriage 10 in this embodiment is designed such that the body 11 includes a first surface region 25, which extends along the first segment UK1-1 of the roller circulation channel UK1 and is always parallel to the first plane E1, such that in the first segment UK1-1 of the roller circulation channel UK1, the rollers R1 in the first roller row RR1 abut against the first surface region 25 of the body 11 with the front end face of the segment TS-1 of the corresponding roller R1 away from the separating web TS; and when the guide carriage 10 moves along the longitudinal direction of the profile guide rail 5, these rollers R1 are guided on the first surface region 25 of the body 11.

[0079] Accordingly, the guide carriage 10 in this embodiment is designed such that the main body 11 includes a first surface region 25, which extends along the first segment UK2-1 of the roller circulation channel UK2 and is always parallel to the first plane E2, such that in the first segment UK2-1 of the roller circulation channel UK2, the rollers R1 in the first roller row RR1 abut against the first surface region 25 of the main body 11 with the front end face of the segment TS-1 of the corresponding roller R1 away from the separating web TS; when the guide carriage 10 moves along the longitudinal direction of the profile guide rail 5, these rollers R1 are guided within the first surface region 25 of the main body 11.

[0080] like Figure 8 and 9 As shown, each roller R1, R2 is rotationally symmetrical about its respective longitudinal axis, and the diameter D of each roller changes along the longitudinal axis of the roller, such that the diameter D of roller R1, R2 is at its maximum value Dmax in the intermediate region ME located between the two opposing front end faces SF1, SF2 of the roller; and starting from the intermediate region ME between the two opposing front end faces SF1, SF2, along the longitudinal axis of the roller, the diameter D continuously decreases as the distance DX between it and the intermediate region ME increases, and this decrease is a function of the distance DX from the intermediate region ME.

[0081] Furthermore, it can be seen that the segment TS-1 of the separating web TS extends parallel to the first plane E1 in the first segment UK1-1 of the roller circulation channel UK1 of the roller deflection device UV1, thereby making the separating web have a height relative to one of the roller running track surfaces 20 of the first segment UK1-1 of the roller circulation channel UK1 of the roller deflection device UV1 defined by the main body 11, which is less than the maximum value Dmax of the diameters of the rollers R1 and R2.

[0082] Additionally, the segment TS-1 of the separating web TS extends parallel to the first plane E2 in the first segment UK2-1 of the roller circulation channel UK2 of the roller deflection device UV2, thereby making the separating web have a height relative to one of the roller running track surfaces 21 of the first segment UK2-1 of the roller circulation channel UK2 of the roller deflection device UV2 defined by the main body 11, which is less than the maximum value Dmax of the diameters of the rollers R1 and R2.

[0083] Figure 8 It is further shown that in the first segments UK1-1 and UK2-1 of the roller circulation channels UK1 and UK2 of the roller deflection devices UV1 and UV2, the segment TS-1 of the partition web TS extends parallel to the first plane E1 and E2 relative to the body 11, defining one of the roller running track surfaces 20 and 21 of the first segments UK1-1 and UK2-1 of the roller circulation channels UK1 and UK2 of the roller deflection devices UV1 and UV2, thereby making the partition web have an end segment TSE spaced apart from one of the roller running track surfaces 20 and 21 of the body 11.

[0084] The segment TS-1 of the separating web TS includes a first protrusion V1 in the spaced-apart end segment TSE. This first protrusion extends perpendicularly to the first planes E1 and E2, such that the first protrusion V1 is suspended above the roller R1 at the region MSF1 and MSF2 of the outer circumferential surface MF of the roller R1 in the first roller row RR1 that abuts against the first side surface F1 of the separating web TS. Figure 8 and Figure 9 Furthermore, the segment TS-1 of the separating web TS includes a second protrusion V2 in the spaced-out end segment TSE, the second protrusion extending perpendicularly to the first planes E1, E2, such that the second protrusion V2 is suspended above the roller R2 at the region MSF1, MSF2 of the outer circumferential surface MF of the roller R2 in the second roller row RR2 that abuts against the second side surface F2 of the separating web TS. Figure 8 and Figure 9 ).

[0085] like Figures 7-9 As shown, the roller deflection devices UV1 and UV2 may include a rod 60 extending longitudinally along the profile guide rail 5, disposed near the surface region 25 of the body 11, such that the rod 60 abuts against the front end face of the roller R1 away from the separating web TS. The rod 60 includes a protrusion V1 that is suspended above a region of the outer circumferential surface MF of the roller R1 abutting against the rod 60.

[0086] Furthermore, the roller deflection devices UV1 and UV2 may include a rod 61 extending along the longitudinal direction of the profile guide rail 5, the rod 61 being configured such that it abuts against the front end face of the roller R2 away from the separating web TS. The rod 61 includes a protrusion V2 that is suspended above a region of the outer circumferential surface MF of the roller R1 that abuts against the rod 61.

[0087] refer to Figure 8 The separating web TS includes a first groove N1 extending along the roller circulation channels UK1 and UK2 on its first side surface F1, so that lubricant for lubricating roller R1 in the first roller row RR1 can be introduced into the roller circulation channels UK1 and UK2 through the first groove N1. Correspondingly, the separating web TS has a second groove N2 extending along the roller circulation channels UK1 and UK2 on its second side surface F2, so that lubricant for lubricating roller R2 in the second roller row RR2 can be introduced into the roller circulation channels UK1 and UK2 through the second groove N2.

[0088] The lubricant to be conveyed through the groove N1 or N2 can be supplied to the groove N1 or N2 via the inlet 13 formed on the end cap 12 (through a connecting pipe not shown in the figure).
