Description
本創作係關於一種直線運動模組，特別係關於一種具有自潤功能之直線運動模組。This creation is about a linear motion module, especially for a linear motion module with self-lubricating function.
直線運動模組係由一線性軌道、一滑座以及複數滾珠所構成，藉由滾珠於循環通道中持續滾動，帶動滑座及其上機構沿線性軌道移動，使得該機構得以執行所需作業或表現功能。其中，不論滾珠與線性軌道或與滑座間在相對移動時，接觸面上都存在有摩擦力。一如一般物理理論所熟知，摩擦力往往是動能消耗的最大來源，且在使動能轉化為熱能的過程中，不僅虛耗大量能量，更為設備帶來過熱的潛藏危險。The linear motion module is composed of a linear track, a sliding seat and a plurality of balls. The rolling of the balls in the circulation channel continuously drives the sliding block and the upper mechanism to move along the linear track, so that the mechanism can perform the required work or Performance function. Among them, there is frictional force on the contact surface regardless of the relative movement between the ball and the linear track or with the slide. As is well known in general physics theory, friction is often the largest source of kinetic energy consumption, and in the process of converting kinetic energy into heat energy, not only a large amount of energy is consumed, but also the hidden danger of overheating of equipment.
針對上述問題，業界已藉由提出多種潤滑技術試圖解決，期能透過提供油料降低摩擦係數，提昇直線運動模組作動時的能量利用率，使動能得以完整地用於驅動機構運作。目前已知的主要作法係包括以油槍手動定時對直線運動模組補充油料，或者藉由外接式管路供應。但顯而易見地，前述兩種方式均止於由外部進行油料供給，因而實務上常發生作業不當使得潤滑油料濺灑或滴落的問題。另外，油料添加的多寡亦不易估算，導致時有供油過多造成油料外溢，或是供油不足潤滑效力不彰的困擾。In response to the above problems, the industry has attempted to solve a variety of lubrication techniques by providing a plurality of lubrication technologies to reduce the friction coefficient and improve the energy utilization rate of the linear motion module during operation, so that the kinetic energy can be completely used for the operation of the drive mechanism. The main known methods currently include replenishing the linear motion module with oil gun manual timing or supplying it through an external piping. However, it is obvious that both of the above methods stop the supply of the oil from the outside, and thus the problem of improper operation causes the lubricant to splash or drip. In addition, the amount of oil added is not easy to estimate, resulting in excessive oil supply, oil spillover, or insufficient lubrication.
雖然陸續有業者開發出掛載自潤元件的直線運動模組，然而，掛載式的自潤元件卻有暴露於外部環境，進而因毛細作用，導致吸附大量的水氣、塵埃或異物等缺點，不僅直接影響本身的油料傳遞與再吸收的能力，更因為暴露於外，而常有油料外滲的問題，總結而言，難說是一種良好的潤滑手段。Although some operators have developed linear motion modules with self-lubricating components, the self-lubricating components of the mounting type are exposed to the external environment, and thus cause a large amount of moisture, dust or foreign matter due to capillary action. It not only directly affects its ability to transfer and resorb oil, but also because of exposure to oil, and often the problem of oil leakage. In summary, it is difficult to say that it is a good means of lubrication.
因此，如何提供一種直線運動模組，其藉由自潤組件的設置，因而不需由外部供給潤滑油料，即可自動實施潤滑，且更能提供自潤 組件適當的防護，以隔絕水氣及塵埃，提高潤滑效率及使用壽命，已成為重要課題之一。Therefore, how to provide a linear motion module, which is provided by the self-lubricating component, can automatically perform lubrication without externally supplying lubricating oil, and can provide self-lubrication. Proper protection of components to isolate moisture and dust, improve lubrication efficiency and service life has become one of the important topics.

The self-drying unit 231 has a structure in which at least one protruding portion P corresponds to and contacts one of the track grooves 11, and the lubricating material is transferred from the drying unit 231 and applied to the track groove 11 of the linear track 1. Preferably, the fixing unit 232 has at least one opening O corresponding to the track groove 11, and the protrusion P can contact one of the track grooves 11 through the opening O. The total number of the projections P preferably corresponds to the number of the track grooves 11 of the linear track 1, and the number of the openings O corresponds to the number of the projections P. As described above, the linear track 1 of the present embodiment has four track grooves 11, and the two self-drying units 231 simultaneously contact the linear track 1 and are accommodated on the side of the fixed unit 232 corresponding to the linear track 1, and this creation The fixing unit 232 is not limited to correspond to the upper side, the left side, the right side, or a combination thereof of the linear track 1. In the present embodiment, each of the lubrication units 231 has two protrusions P, and each of the protrusions P passes through the opening O to be in contact with the track groove 11. Therefore, the two self-lubricating units 231 have four protruding portions P corresponding to the four track grooves 11 respectively.
於其他實施例中，如圖5B所示，圖5B為本創作另一實施例之自潤組件23a裝設於線性軌道1a的示意圖。自潤單元231a亦可為一體成型的結構，且自潤單元231a同時接觸對應線性軌道1a的相對二側，並設置於固定單元232a的容置空間S(請搭配圖4所示)。換言之，固定單元 232a的容置空間S的構型與自潤單元231a須相互對應。而自潤單元231a則具有四個突出部P，對應接觸於各個軌道槽11a，但本創作不以突出部P的數量為限。In other embodiments, as shown in FIG. 5B, FIG. 5B is a schematic diagram of the self-lubricating assembly 23a of the other embodiment being mounted on the linear track 1a. The self-wetting unit 231a may also be an integrally formed structure, and the self-wetting unit 231a simultaneously contacts the opposite sides of the corresponding linear track 1a, and is disposed in the accommodating space S of the fixed unit 232a (please be shown in FIG. 4). In other words, the fixed unit The configuration of the accommodating space S of 232a and the self-lubricating unit 231a must correspond to each other. The self-wetting unit 231a has four protruding portions P corresponding to the respective track grooves 11a, but the present creation is not limited to the number of the protruding portions P.
於本領域具通常知識者所知，在本創作其他實施例中，滑座2亦可僅具有一個自潤組件23對應線性軌道1的其中一側，且自潤組件23可僅具一自潤單元231，本創作不限制自潤單元231及其突出部P的數量及構型，僅需一個自潤單元231具有一突出部P，並對應其中之一的軌道槽11，即可達到傳遞潤滑油料且塗佈於軌道槽11之功效，本創作不以此為限。As is known to those skilled in the art, in other embodiments of the present invention, the slider 2 may have only one side of the linear component 1 corresponding to the self-lubricating component 23, and the self-lubricating component 23 may have only one self-lubricating component. The unit 231 does not limit the number and configuration of the self-lubricating unit 231 and its protruding portion P. Only one self-lubricating unit 231 has a protruding portion P, and corresponding to one of the track grooves 11, the lubrication can be achieved. The effect of the oil material and coating on the track groove 11 is not limited to this creation.
較佳的，如圖4所示，固定單元232具有第一連接部C11、C12，自潤單元231具有第二連接部C21、C22。其中，第一連接部C11與第二連接部C21相互配合，而第一連接部C12與第二連接部C22相互配合。當然，於其他實施例中，可僅以一組第一連接部C12與第二連接部C22相互配合，以固定自潤單元231。於本實施例中，第一連接部C11、C12為一凸部，第二連接部C21、C22為一凹部。第一連接部C11、C12與第二連接部C21、C22相互卡合，使自潤單元231可穩固的設置於固定單元232，以避免滑座2於線性軌道1上滑動而帶動自潤組件23移動時，自潤單元231因摩擦力而自固定單元232脫落的情形。當然，本創作亦不限制第一連接部C11、C12與第二連接部C21、C22的構型，僅需可相互配合，當然亦可增設其他相互配合的結構，使自潤單元231穩固的設置於固定單元232。Preferably, as shown in FIG. 4, the fixing unit 232 has first connecting portions C11 and C12, and the self-lubricating unit 231 has second connecting portions C21 and C22. The first connecting portion C11 and the second connecting portion C21 cooperate with each other, and the first connecting portion C12 and the second connecting portion C22 cooperate with each other. Of course, in other embodiments, only one set of the first connecting portion C12 and the second connecting portion C22 can cooperate with each other to fix the self-lubricating unit 231. In the embodiment, the first connecting portions C11 and C12 are a convex portion, and the second connecting portions C21 and C22 are a concave portion. The first connecting portions C11 and C12 and the second connecting portions C21 and C22 are engaged with each other, so that the self-lubricating unit 231 can be stably disposed on the fixing unit 232 to prevent the sliding seat 2 from sliding on the linear rail 1 to drive the self-lubricating component 23 . When moving, the self-drying unit 231 is detached from the fixing unit 232 due to frictional force. Of course, the present invention does not limit the configuration of the first connecting portions C11 and C12 and the second connecting portions C21 and C22, and only needs to be matched with each other. Of course, other mutually matching structures may be added to ensure the stable setting of the self-lubricating unit 231. In the fixing unit 232.
此外，自潤單元231可為多孔隙含油材料或高分子含油材料，例如羊毛氈或泡棉，透過高效率之毛細現象吸含潤滑油料，再傳遞至線性軌道1。由於自潤單元231係容置於固定單元232內，故可以一定程度地阻絕環境中的水氣、塵埃及異物，從而避免自潤單元231吸收過多水氣，而由傳遞油料變成傳遞水分，折損潤滑效果。另外，防塵組件24具有複數防塵單元241，而該些防塵單元241的其中之一蓋設於自潤組件23(如圖1所示)，以達到更佳的隔絕效果。In addition, the self-drying unit 231 may be a porous oil-containing material or a polymer oil-containing material, such as wool felt or foam, which absorbs the lubricating oil through a high-efficiency capillary phenomenon and transmits it to the linear orbit 1 . Since the self-lubricating unit 231 is housed in the fixing unit 232, moisture, dust and foreign matter in the environment can be blocked to a certain extent, thereby preventing the self-lubricating unit 231 from absorbing too much water and gas, and transferring the oil into water to transfer moisture. Lubrication effect. In addition, the dustproof assembly 24 has a plurality of dustproof units 241, and one of the dustproof units 241 is disposed on the self-lubricating assembly 23 (as shown in FIG. 1) to achieve a better insulation effect.
綜合上述結構，當滑座2於線性軌道1上滑動時，將帶動自潤組件23移動，且由於自潤單元231的突出部P接觸軌道槽11，因此能同時供應油料進行軌道槽面的潤滑作業，故具有自潤功能，且可延長原本固 定對線性軌道1上油進行潤滑養護之間隔。更重要的是，固定單元232於相反於滑座本體21的一側有容置空間S，而自潤單元231容置於容置空間S而受到固定單元232的固持，以及同時受到防塵組件24及固定單元232的防護，即自潤組件23的外側設置防塵組件24，故不易接觸到外在環境的水氣、塵埃及異物，能夠長時間地維持高作業效率。In combination with the above structure, when the carriage 2 slides on the linear rail 1, the self-lubricating assembly 23 is driven to move, and since the protruding portion P of the self-lubricating unit 231 contacts the track groove 11, the oil can be simultaneously supplied for lubrication of the track groove surface. Homework, so it has a self-lubricating function and can extend the original solid The interval between lubrication and maintenance of the oil on the linear track 1 is determined. More importantly, the fixing unit 232 has an accommodating space S on the side opposite to the slider body 21, and the self-lubricating unit 231 is accommodated in the accommodating space S and is held by the fixing unit 232, and is simultaneously subjected to the dustproof assembly 24. The protection of the fixing unit 232, that is, the dust-proof assembly 24 is provided on the outer side of the self-lubricating unit 23, so that it is difficult to contact the moisture, dust and foreign matter in the external environment, and the high work efficiency can be maintained for a long time.
圖5C為圖5A所示之B區域的放大示意圖，請同時參考圖5A及圖5C所示。在本實施例中，自潤單元231之突出部P具有與線性軌道1之軌道槽11對應的形狀，因此，當直線運動模組L組裝完成後，自潤單元231之突出部P得以與軌道槽11緊密貼合，故當滑座2於線性軌道1滑動而同時帶動自潤組件23，由於摩擦力及自潤單元231為多孔隙含油材料或高分子含油材料的材質，使得突出部P受到軌道槽11擠壓的同時，進而釋出潤滑油料於軌道槽11，維持較佳的潤滑功效。其中，突出部P之截面形狀可例如圖中所示之圓弧形，且較佳的，自潤單元231的突出部P與軌道槽11接觸且相互干涉(如圖5C的虛線部分)，而該接觸干涉量T1介於0.05mm至0.3mm之間，其中包括0.05mm至0.3mm之間任意數值的組合。而於其他實施態樣中，突出部P之截面形狀亦可為歌德弧形，以與同樣為歌德弧形的軌道槽面配合，本創作在此無特別限制，而以能全面性地觸及滾珠的滾動位置為佳，以於一次作動中達成所需的潤滑作業。當然在此條件下，突出部P之大小及接觸干涉量則非限制重點。FIG. 5C is an enlarged schematic view of the B area shown in FIG. 5A, please refer to FIG. 5A and FIG. 5C at the same time. In the present embodiment, the protruding portion P of the self-wetting unit 231 has a shape corresponding to the track groove 11 of the linear track 1, and therefore, when the linear motion module L is assembled, the protruding portion P of the self-drying unit 231 is enabled and tracked. The groove 11 is closely attached, so that when the sliding seat 2 slides on the linear rail 1 and simultaneously drives the self-lubricating component 23, the protruding portion P is subjected to the frictional force and the self-lubricating unit 231 is a material of the porous oil-containing material or the polymer oil-containing material. When the track groove 11 is squeezed, the lubricating oil is released to the track groove 11 to maintain better lubricating efficiency. The cross-sectional shape of the protruding portion P may be, for example, a circular arc shape as shown in the drawing, and preferably, the protruding portion P of the self-lubricating unit 231 is in contact with the track groove 11 and interferes with each other (as shown by a broken line in FIG. 5C). The contact interference amount T1 is between 0.05 mm and 0.3 mm, including a combination of any value between 0.05 mm and 0.3 mm. In other embodiments, the cross-sectional shape of the protrusion P may also be a Goethe arc shape to cooperate with the track groove surface which is also a Goethe arc shape. The present invention is not particularly limited herein, and the ball can be fully touched. The rolling position is preferred to achieve the required lubrication in one actuation. Of course, under this condition, the size of the protrusion P and the amount of contact interference are not limited.
進而言之，如圖1及圖2所示，防塵組件24設置於自潤組件23相對於端蓋22的一側。防塵組件24可以具有與滑座本體21之端面ES對應的構型，以橫跨線性軌道1之兩側，至於尺寸則無限制，但以契合端面ES大小者為佳。防塵組件24的材料例如包括塑膠或塑鋼，且可透過例如射出成形或由組件組裝形成。較佳的，防塵組件24包括一間隔件242，其夾設於二防塵單元241之間。為求清楚說明，以下將設置於外側的防塵單元241稱為外防塵單元241a，而設置於內側的防塵單元241稱為內防塵單元241b。其中，外防塵單元241a、間隔件242及內防塵單元241b係以由外部朝向端蓋22之方向依序設置，使間隔件242設置於外防塵單元241a及內防塵單元241b之間。若以滑座本體21的長軸方向來看，內防塵單元 241b、間隔件242及外防塵單元241a係以遠離端蓋22的方向依序設置。於本實施例中，外防塵單元241a及內防塵單元241b皆為二防塵片所共同組成的防塵件，而於其他實施例中，外防塵單元241a及內防塵單元241b亦可以為單一構件，本創作不以此為限。於本實施例中，內防塵單元241b蓋設於自潤組件23，故自潤單元231設於固定單元232與內防塵單元241b之間，可有效的隔絕水氣或灰塵。且因內防塵單元241b蓋設於固定單元232外側，使自潤單元231同時受到固定單元232及內防塵單元241b的防護，故無須在自潤組件23中另設外套件蓋住自潤單元231，而此種設計可提升組裝的效率。Further, as shown in FIGS. 1 and 2, the dustproof member 24 is disposed on the side of the self-lubricating assembly 23 with respect to the end cap 22. The dust-proof assembly 24 may have a configuration corresponding to the end face ES of the carriage body 21 so as to straddle both sides of the linear track 1, and the size is not limited, but it is preferable to match the size of the end face ES. The material of the dustproof assembly 24 includes, for example, plastic or plastic steel, and can be formed, for example, by injection molding or by assembly of components. Preferably, the dustproof assembly 24 includes a spacer 242 that is sandwiched between the two dustproof units 241. For the sake of clarity, the dustproof unit 241 provided outside is referred to as an outer dustproof unit 241a, and the dustproof unit 241 disposed inside is referred to as an inner dustproof unit 241b. The outer dustproof unit 241a, the spacer 242, and the inner dustproof unit 241b are sequentially disposed from the outside toward the end cover 22, and the spacer 242 is disposed between the outer dustproof unit 241a and the inner dustproof unit 241b. If the longitudinal direction of the slider body 21 is viewed, the inner dustproof unit The 241b, the spacer 242, and the outer dustproof unit 241a are sequentially disposed away from the end cover 22. In the present embodiment, the outer dust-proof unit 241a and the inner dust-proof unit 241b are both dust-proof members. In other embodiments, the outer dust-proof unit 241a and the inner dust-proof unit 241b can also be a single component. Creation is not limited to this. In the present embodiment, the inner dustproof unit 241b is disposed on the self-lubricating unit 23, so that the self-lubricating unit 231 is disposed between the fixing unit 232 and the inner dustproof unit 241b, and can effectively block moisture or dust. Moreover, since the inner dustproof unit 241b is disposed outside the fixing unit 232, the self-lubricating unit 231 is protected by the fixing unit 232 and the inner dustproof unit 241b at the same time. Therefore, it is not necessary to provide an outer sleeve in the self-lubricating assembly 23 to cover the self-lubricating unit 231. And this design can improve the efficiency of assembly.
圖6為圖2所示之內防塵單元241b裝設於線性軌道的示意圖，需特別註明的是，圖6為由內防塵單元241b向滑座本體21觀察的示意圖，故外防塵單元241a的部分可搭配圖1及圖2所示。如圖6所示，防塵組件24與軌道槽11相互接觸。較佳的，外防塵單元241a及內防塵單元241b均與軌道槽11相互干涉(即圖6所示之虛線)。抑或是，外防塵單元241a、內防塵單元241b的其中之一與軌道槽11相互干涉；若以內防塵單元241b與軌道槽11相互干涉，則可使設置於滑座2之最外側的外防塵單元241a先阻擋較大的異物，再由內防塵單元241b刮除軌道槽11上的灰塵或異物後，自潤單元231的突出部P再將潤滑油料塗覆於軌道槽11。換言之，可避免潤滑油料沾染於具有灰塵或異物的軌道槽11，使得灰塵或異物更難清除進而進入滑座本體21，進而損壞直線運動模組L。而防塵組件24整體的設置於滑座2的最外側，且具有外防塵單元241a及內防塵單元241b兩道的防塵結構，更可提高避免灰塵或異物進入滑座本體21之功效。6 is a schematic view showing the inner dustproof unit 241b shown in FIG. 2 mounted on a linear rail. It should be particularly noted that FIG. 6 is a schematic view of the inner dustproof unit 241b viewed from the slide body 21, so that the outer dustproof unit 241a is partially Can be combined with Figure 1 and Figure 2. As shown in FIG. 6, the dustproof member 24 and the track groove 11 are in contact with each other. Preferably, the outer dustproof unit 241a and the inner dustproof unit 241b both interfere with the track groove 11 (ie, the broken line shown in FIG. 6). Or, one of the outer dustproof unit 241a and the inner dustproof unit 241b interferes with the track groove 11; if the inner dustproof unit 241b and the track groove 11 interfere with each other, the outer dustproof unit provided on the outermost side of the slide 2 can be used. 241a first blocks a large foreign matter, and after the inner dustproof unit 241b scrapes off the dust or foreign matter on the track groove 11, the protruding portion P of the self-drying unit 231 applies the lubricating oil material to the track groove 11. In other words, it is possible to prevent the lubricating oil material from being contaminated with the track groove 11 having dust or foreign matter, so that dust or foreign matter is more difficult to remove and enter the sliding seat body 21, thereby damaging the linear motion module L. The dust-proof assembly 24 is integrally disposed on the outermost side of the slide 2 and has a dust-proof structure of the outer dust-proof unit 241a and the inner dust-proof unit 241b, thereby improving the effect of preventing dust or foreign matter from entering the slide body 21.
另外，於本實施例中，如圖2所示，滑座2可更包括四條防塵件DP，分別連結滑座本體21的底側，及夾設於線性軌道1上側及端蓋22之滾珠保持部BH之間。防塵件DP共同用於阻擋塵埃或異物由線性軌道1及滑座本體21上下兩空隙進入直線運動模組L內部。In addition, in this embodiment, as shown in FIG. 2, the sliding seat 2 can further include four dust-proof members DP, which are respectively coupled to the bottom side of the sliding seat body 21, and the balls held on the upper side of the linear rail 1 and the end cover 22 are held. Between the BH. The dustproof member DP is commonly used to block dust or foreign matter from entering the inside of the linear motion module L by the linear rail 1 and the upper and lower gaps of the slider body 21.
另外，在本實施例中，滑座2可更包含複數迴流元件25，其具有長管形結構，且長管形結構緊密地容置於外迴流通道212中，取代外迴流通道212直接與滾珠3接觸，形成較平順且斷差較少的循環通道， 減少鑽孔造成外迴流通道212之孔道面粗糙及/或熱處理變形的問題。本實施例之迴流元件25可獨立製成，再沿滑座本體21之長軸方向於外迴流通道212中結合。各迴流元件25可藉由扣合、卡合、黏合、鎖合、嵌合、或其組合的方式分別組裝於滑座本體21之兩端面ES。當然，在其他實施例中，亦可將滑座本體21***模具中，直接於外迴流通道212內部射出成型迴流元件25，以使滑座本體21與迴流元件25一體成形。而如本領域具通常知識者所知，直線運動模組L當然可以在不使用迴流元件25的情況下，而直接以外迴流通道212，配合端蓋22的迴流彎槽221，以形成供滾珠作動的循環通道，本創作不以此為限。In addition, in this embodiment, the carriage 2 may further include a plurality of reflow elements 25 having a long tubular structure, and the long tubular structure is closely accommodated in the outer recirculation passage 212, instead of the outer recirculation passage 212 directly with the balls. 3 contact, forming a smoother and less interrupted circulation channel, Reducing the problem of the hole surface roughness and/or heat treatment deformation of the outer return passage 212 caused by the drilling. The reflow element 25 of the present embodiment can be independently fabricated and joined in the outer return passage 212 along the long axis direction of the carriage body 21. Each of the reflow elements 25 can be assembled to the opposite end faces ES of the carriage body 21 by fastening, snapping, bonding, locking, fitting, or a combination thereof. Of course, in other embodiments, the slider body 21 can also be inserted into the mold to directly form the reflow element 25 inside the outer recirculation passage 212 to integrally form the carriage body 21 and the reflow element 25. As is known to those skilled in the art, the linear motion module L can of course be fitted with the return flow channel 212 of the end cap 22 to form a ball for movement without using the reflow element 25. The circulation channel, this creation is not limited to this.
綜上所述，依據本創作之直線運動模組，其具有能裝設於端蓋上的自潤組件，故可以在作動過程中，自潤組件的自潤單元可直接提供線性軌道潤滑油料，以降低滾珠與線性軌道及與滑座間的摩擦力，減少對於外部輸入油料的依賴，且可延長原本固定對線性軌道進行潤滑養護之間隔，減少添加過程的不便以及估量誤差所帶來的影響。此外，本創作之自潤組件，其具有固定單元以供自潤單元容置，且防塵單元其中之一蓋設於自潤組件，使自潤單元約束於固定單元內，能主動隔絕環境中的水氣、塵埃及異物，以避免此些雜質成分干擾油料的毛細作用，妨礙潤滑作業。另外，亦由於自潤單元包覆於固定單元內，故油料不易外滲，而免除無謂的消耗，更使得塗佈油料具有針對性。In summary, the linear motion module according to the present invention has a self-lubricating component that can be mounted on the end cover, so that the linear track lubricating oil material can be directly supplied from the self-lubricating unit of the self-lubricating component during the actuation process. In order to reduce the friction between the ball and the linear track and the sliding seat, the dependence on the external input oil is reduced, and the interval of lubricating and curing the linear track can be extended, the inconvenience of the adding process and the influence of the estimation error are reduced. In addition, the self-lubricating component of the present invention has a fixing unit for accommodating the self-lubricating unit, and one of the dustproof units is covered by the self-lubricating component, so that the self-lubricating unit is restrained in the fixed unit, and the environment can be actively isolated. Water vapor, dust and foreign matter, to prevent these impurities from interfering with the capillary action of the oil and hinder the lubrication operation. In addition, since the self-lubricating unit is coated in the fixing unit, the oil material is not easily extravasated, thereby eliminating unnecessary consumption and making the coating oil material specific.
另外，本創作之防塵組件的整體設置於滑座的最外側，且具有複數個防塵單元之多道防塵結構，更可提高避免灰塵或異物進入滑座本體，以增進直線運動模組的防塵功效。In addition, the dustproof component of the present invention is integrally disposed on the outermost side of the sliding seat, and has multiple dustproof structures of a plurality of dustproof units, thereby improving dust and foreign matter from entering the sliding seat body to improve the dustproof effect of the linear motion module. .
