Detailed Description
Please refer to fig. 1 to 13, which are exemplary embodiments of the present invention, and it should be noted that, in the exemplary embodiments, the related numbers and shapes mentioned in the accompanying drawings are only used for describing the embodiments of the present invention in detail, so as to facilitate the understanding of the contents of the present invention, and not for limiting the protection scope of the present invention.
As shown in fig. 1 and fig. 2, the present embodiment discloses a linear guideway 1000, and particularly relates to a standard type linear guideway 1000. The linear sliding rail 1000 includes a long rail 200, a sliding block module 300 slidably disposed on the rail 200, and two end modules 100 mounted at opposite ends of the sliding block module 300 and slidably disposed on the rail 200.
The rail 200 includes four bearing surfaces 201 parallel to the length direction thereof, and the four bearing surfaces 201 are located on two opposite sides of the rail 200. Moreover, the linear guideway 1000 further includes a plurality of balls (not shown) rolling on the slider module 300 and the track 200, but the balls are not improved in this case, so the present embodiment is not described in detail.
In addition, the end module 100 is illustrated in the embodiment by the slider module 300 and the rail 200, which are collocated in the drawings, but the invention is not limited thereto. For example, in other embodiments not shown, the end module 100 may be used alone (e.g., sold) or in combination with other components.
Furthermore, since the two end modules 100 have substantially the same or symmetrical structure in the present embodiment, only the structure of a single end module 100 will be described below for convenience of description. However, in other embodiments of the invention not shown, the two end modules 100 may also be of different configurations from each other.
As shown in fig. 1, 3 and 4, the end module 100 includes a receiving box 1 fixed to the slider module 300, an oil storage member 2 disposed in the receiving box 1, and two contact members 3 embedded in the oil storage member 2 and positioned in the receiving box 1. The friction coefficient of the oil storage member 2 is greater than the friction coefficient of each contact member 3, and the friction coefficient of the oil storage member 2 is preferably between 0.35 and 0.55, and the friction coefficient of each contact member 3 is preferably between 0.15 and 0.25, but the invention is not limited thereto. In the present embodiment, the friction coefficient between the oil storage member 2 and the contact member 3 is measured by sliding on the bearing surface 201 of the rail 200 without absorbing the lubricant, but the present invention is not limited thereto.
In other words, the density of the oil storage member 2 is smaller than that of each of the above-described contact members 3, and the density of the oil storage member 2 is preferably between 0.05g/cm3~0.25g/cm3And the density of each of the above-mentioned contact members 3 is preferably in the range of 0.15g/cm3~0.45g/cm3. Accordingly, the end module 100 of the present embodiment preferably further enhances the lubrication effect by matching the oil reservoirs 2 and the contact elements 3 made of different materials.
It should be noted that the oil storage member 2 and the two contact members 3 can be defined as a lubrication unit in the present embodiment, and the lubrication unit is not limited to be applied to the accommodating box 1 as shown in the drawings; that is, the lubrication unit may be used alone (e.g., sold) or in combination with other components. In addition, the construction of each component of the end module 100 will be described separately, and the connection relationship between each component of the end module 100 will be described in due course.
As shown in fig. 5 to 8, the receiving box 1 is substantially in an inverted U shape and has a lubricating oil groove 11 formed therein, and the receiving box 1 (inner edge) has four positioning holes 12 respectively facing the four bearing surfaces 201 and communicating with the lubricating oil groove 11. Further, the lubricant oil groove 11 in this embodiment includes two sub oil grooves 111 separated from each other, and the four positioning ports 12 are respectively connected to the two sub oil grooves 111 two by two.
Furthermore, the accommodating box 1 (top portion) is formed with two oil injection vents 13 respectively communicating with the two oil sub-grooves 111 for injecting a lubricating oil (not shown) into the accommodating box 1, but the invention is not limited thereto. In other words, the lubricating oil groove 11 (or the oil groove 111) in the accommodating box 1 can be communicated with the external space only through the positioning hole 12 or the oil filling ventilation hole 13.
As shown in fig. 3, 7 and 8, the material of the oil storage member 2 is, for example, a cotton material, such as: polypropylene (PP) cotton, Polyurethane (PU) cotton, ethylene-vinyl acetate copolymer (EVA) cotton, and the oil storage 2 is disposed in the lubricating oil groove 11 of the accommodating box 1 to absorb and store lubricating oil. The oil reservoir 2 has two fitting grooves 211 that communicate with the four positioning ports 12 (that is, the two fitting grooves 211 face each other), and the inner edge of each fitting groove 211 is substantially C-shaped.
More specifically, in the present embodiment, the oil storage member 2 includes two oil storage bodies 21 spaced apart from each other, and the two fitting grooves 211 are formed at positions of the two oil storage bodies 21 facing each other. However, in other embodiments of the present invention, which are not shown, the lubricant sump 11 in the receiving box 1 may not be formed with a compartment, and the oil reservoir 2 may be of a single-piece construction so that the oil reservoir 2 can be inserted into the lubricant sump 11 in the receiving box 1.
Furthermore, the two oil storage bodies 21 are respectively disposed in the two oil grooves 111 of the accommodating box 1, the two oil storage bodies 21 respectively correspond to the two oil injection ventilation holes 13, and each oil storage body 21 is formed with a notch 212 communicated with the corresponding oil injection ventilation hole 13. It should be noted that each oil storage body 21 is illustrated as a two-piece stacked structure in the present embodiment, but in other embodiments not shown in the present invention, each oil storage body 21 may also be a one-piece structure.
As shown in fig. 3, 7 and 8, the material of each contact member 3 is, for example, a wool felt or a pure cotton, and each contact member 3 is C-shaped and includes a long base portion 31, two neck portions 32 connected to two ends of the base portion 31, and two contact end portions 33 connected to the two neck portions 32, respectively. The two contacts 3 are respectively embedded in the two embedding grooves 211 of the oil storage 2 (or the two oil storage bodies 21), and (the base part 31 and the two neck parts 32 of) each contact 3 are pressed against the inner wall of the corresponding embedding groove 211, so that the oil storage 2 can transmit lubricating oil from the inner wall of each embedding groove 211 to the corresponding contact 3 through a capillary phenomenon. Further, the end module 100 forms the oil storage member 2 into two oil storage bodies 21 separated from each other, so that the two oil storage bodies 21 can supply the lubricating oil toward the two contact members 3 separately and independently without interruption.
Furthermore, the two neck portions 32 of each contact 3 are fastened to the position of the accommodating box 1 between two adjacent positioning openings 12 (as shown in fig. 8), and the four contact end portions 33 of the two contacts 3 respectively pass through the four positioning openings 12 of the accommodating box 1 to protrude out of the lubricating oil groove 11 and respectively abut against the four bearing surfaces 201 of the rail 200.
More specifically, each contact tip portion 33 is a cylindrical segment and includes an arc surface 331 abutting against the corresponding bearing surface 201 and an oil outlet surface 332 aligned with the corresponding positioning hole 12. The oil outlet section 332 of each contact terminal portion 33 forms a projection area by orthographic projection along the normal direction thereof toward the rail 200, and the projection area covers the entire corresponding bearing surface 201, but the invention is not limited thereto.
In other words, in a cross-section of each contact member 3 perpendicular to the length direction of the rail 200 (as shown in fig. 8), each oil exit section 332 has a width W332, and each neck portion 32 has a minimum width W32, and the minimum width W32 of each neck portion 32 is 60% to 77% (preferably 65% to 73%) of the width W332 of the oil exit section 332 of the corresponding contact tip portion 33. Accordingly, the contact 3 is designed by the width ratio to ensure that each of the contact terminal portions 33 can stably receive the lubricating oil from the neck portion 32 connected thereto, but the present invention is not limited to the ratio.
As described above, the end module 100 disclosed in this embodiment matches the two contacts 3 embedded in the oil storage member 2 through the oil storage member 2, and the oil storage member 2 can transmit the lubricating oil from the inner wall of the embedding groove 211 to the corresponding contact 3 through capillary phenomenon, so that each contact 3 can continuously obtain the lubricating oil through a short transmission path, thereby providing a better lubricating effect for the rail 200 and the slider module 300.
In addition, as shown in fig. 3, in order to improve the dustproof effect of the linear sliding rail 1000, the end module 100 of the present embodiment provides a receiving box 1 with better dustproof effect, which includes a box body 14, a holding sheet 15 assembled to the box body 14, and a dustproof oil seal sheet 16 detachably mounted outside the holding sheet 15 (and away from the slider module 300). In this embodiment, the holding piece 15 and the box body 14 are assembled with each other to form the lubricating oil groove 11, the four positioning holes 12 and the two oil injection ventilation holes 13.
Accordingly, the dust-proof mechanism of the end module 100 to be described in the present embodiment is mainly formed on the dust-proof oil seal 16, so the detailed structure of the dust-proof oil seal 16 will be further described below, but the invention is not limited thereto. For example, in other embodiments of the present invention, which are not shown, the dust-proof oil seal piece 16 may be a single-piece member integrally formed with the holding piece 15.
As shown in fig. 9 to 13, the dust-proof oil seal piece 16 is an integral structure in this embodiment, and the dust-proof oil seal piece 16 includes a piece body 161 and two wipers 162 and 163 located inside the piece body 161. Each of the wipers 162 and 163 is in an inverted U shape and abuts on the rail 200 without a gap, and the two wipers 162 and 163 abutting against the rail 200 are disposed at intervals. The two scrapers 162 and 163 preferably have different structures, but the invention is not limited thereto.
Accordingly, the two scrapers 162 and 163 with different structures can be used by the dust-proof oil seal sheet 16 to provide different dust-proof oil seal effects respectively through the two scrapers 162 and 163, so that the dust-proof effect can be complemented to a certain extent, and the sliding smoothness of the slider module 300 on the rail 200 can be effectively maintained.
In other words, the two wipers 162 and 163 with different structures of the dust and oil sealing sheet 16 of the present embodiment can provide better dust and oil sealing effects than two wipers with the same or similar structures.
Further, the two wipers 162 and 163 are each abutted against the rail 200 with no gap between the inner side edges thereof; that is, the inner edge of the inverted U-shape of each wiper 162, 163 described above corresponds geometrically to the cross-section of the rail 200. Furthermore, the inner groove 164 is formed between the inner edges of the two wipers 162 and 163 of the dustproof oil seal 16, the inner groove 164 includes two openings 1641 respectively located at two ends thereof, and a space surrounded by the inner groove 164 and the rail 200 can communicate with an external space through the two openings 1641 of the inner groove 164.
In addition, four projection areas formed by orthographically projecting the four contact tip portions 33 of the two contact pieces 3 toward each of the wipers 162 and 163 are located within the outline of each of the wipers 162 and 163; that is, the plurality of projection areas are located on or within the outline of the wipers 162 and 163.
For convenience of explaining the difference between the two wipers 162 and 163 of the dust-proof oil seal 16 of the present embodiment, the two wipers 162 and 163 of the dust-proof oil seal 16 are defined as an inner wiper 162 and an outer wiper 163 in the present embodiment, respectively. The inner wiper 162 is formed by integrally extending the blade body 161, and the outer wiper 163 is formed by integrally extending the inner wiper 162 in a direction away from the slider module 300.
The blade body 161 is generally inverted U-shaped and includes an inner surface 1611 and an outer surface 1612 on opposite sides. The surface of the inner wiper 162 remote from the outer wiper 163 (e.g., the surface of the inner wiper 162 adjacent to the holding blade 15) is coplanar with the inner surface 1611 of the blade body 161 and generally perpendicular to the inner edge of the inner wiper 162. The inner edge of the inner wiper 162 abuts against the rail 200 without a gap, and the width of the inner edge of the inner wiper 162 is preferably less than 50% of the thickness of the blade body 161, so that the blade body 161 can be formed with the inner wiper 162 and the outer wiper 163 in a preferred configuration.
A part of the outer wiper 163 (e.g., a contact portion 1631) protrudes from the outer surface 1612 of the blade body 161, and abuts against the outer wiper 163 portion (e.g., an inner edge of the contact portion 1631) of the rail 200 without a gap, with respect to the inner surface 1611 of the blade body 161, by a distance greater than a distance between the outer surface 1612 and the inner surface 1611 of the blade body 161 (i.e., a thickness of the blade body 161).
In the present embodiment, the outer wiper 163 includes a contact portion 1631 that contacts the rail 200 without a gap and an arm portion 1632 that connects the contact portion 1631 and the inner wiper 162, and the contact portion 1631 is swingable with respect to the inner wiper 162 via the arm portion 1632. That is, the inner edge of the inner wiper 162 and the inner edge of the contact portion 1631 of the outer wiper 163 are spaced apart from each other and are configured to contact the rail 200 without a gap. It should be noted that the outer wiper 163 of the present embodiment has a cantilever function relative to the inner wiper 162, so that the outer wiper 163 can provide better dust-proof effect for the rail 200. Accordingly, the outer wiper 163 of the present embodiment preferably excludes any wiper that does not have the cantilever function, and the two wipers 162 and 163 of the present embodiment preferably excludes two brushes having the same structure.
Further, the sheet body 161 may be concavely formed from the outer surface 1612 thereof with an outer groove 1613 surrounding the outer wiper 163, and the depth of the outer groove 1613 is not more than 50% of the distance between the outer surface 1612 and the inner surface 1611 of the sheet body 161 (that is, the thickness of the sheet body 161). Accordingly, the dust-proof oil seal sheet 16 passes through the outer groove 1613 formed in the sheet body 161, so that the contact portion 1631 of the outer wiper 163 can have a better swinging effect with respect to the inner wiper 162.
[ technical effects of embodiments of the present invention ]
In summary, in the linear sliding rail 1000, the end module 100 and the lubricating unit thereof disclosed in the embodiments of the present invention, the oil storage member 2 is matched with the two contact members 3 embedded in the oil storage member 2, and the oil storage member 2 can transmit the lubricating oil from the inner wall of the embedding groove 211 to the corresponding contact member 3 through the capillary phenomenon, so that each contact member 3 can continuously obtain the lubricating oil through a short transmission path, thereby providing a better lubricating effect for the rail 200 and the slider module 300.
Furthermore, the linear slide rail 1000 and the dust-proof oil seal piece 16 thereof disclosed in the embodiment of the present invention form two wipers 162 and 163 (e.g., an inner wiper 162 and an outer wiper 163) with different structures, so that the two wipers 162 and 163 respectively provide different dust-proof oil-sealing effects, and the dust-proof oil-sealing effects can be complemented to a certain extent, thereby effectively maintaining the smoothness of the sliding of the slider module 300 on the rail 200.
