Description
本發明係關於一種線性傳動元件(linear motion assembly)及其鏈條,此鏈條具有良好的撓性可在線性傳動元件之非圓形的無限循環路徑中循環運動,並間隔相鄰之線性傳動元件之滾動件,使其不相互碰撞及並提供滾動件之潤滑,且鏈條的製造性佳。The present invention relates to a linear motion assembly and a chain thereof having good flexibility for circulating in a non-circular infinite loop path of a linear transmission element and spacing adjacent linear transmission elements The rolling elements are such that they do not collide with each other and provide lubrication of the rolling elements, and the chain is excellent in manufacturability.
線性傳動元件主要包含線性滑軌、滾珠螺桿等,係應用於工具機、電子、自動化、半導體設備之機構上。線性傳動元件之滾動件呈球形或圓柱形,俗稱為滾珠或滾柱,其滾動路徑並不像一般的滾動軸承那樣只是在一個圓形的軌道上運動而已,其特徵是在運動的過程中需要經由一段未承受線性傳動元件之負荷(外力)的迴流路徑來完成整個滾動件的無限循環。由於滾動件的循環路徑並不是一個簡單的圓形,故用以間隔線性傳動元件中各滾動件不相互碰撞的間隔用之鏈條的設計需具有良好的撓性,其需要容易變形並且避免斷裂,設計及製造上均相當困難;與使用不易變形的材質來製造的滾動軸承的保持器是完全不同的。Linear transmission components mainly include linear slides, ball screws, etc., which are used in machines for machine tools, electronics, automation, and semiconductor equipment. The rolling elements of the linear transmission element are spherical or cylindrical, commonly known as balls or rollers, and their rolling paths are not just moving in a circular orbit like a general rolling bearing, which is characterized by the need to A return path that does not withstand the load (external force) of the linear drive element completes the infinite loop of the entire rolling element. Since the circulation path of the rolling member is not a simple circular shape, the design of the chain for spacing the rolling elements in the linear transmission element does not collide with each other needs to have good flexibility, which needs to be easily deformed and avoids breakage. It is quite difficult to design and manufacture; it is completely different from the retainer of a rolling bearing manufactured using a material that is not easily deformed.
習知應用於線性傳動元件中用以間隔各滾動件之鏈條如第一圖所示,為連結許多單獨間隔塊之鏈條設計,圖中之鏈條是將間隔塊511以撓性之連結鏈512相連結,各滾動件11置於兩相鄰間隔塊511間及連結鏈512所構成之空間中滾動。對於間隔塊511和連結鏈512的連結方式設計,若間隔塊511與連結鏈512以組配的方式組合,則需大量人力進行組配(例如日本發明專利特開2005-121208號);若間隔塊511與連結鏈512設計成一體,以模具設計的觀點來看,間隔塊511的表面是內凹之設計,因此脫模時必定會產生倒勾(undercut),模仁與間隔塊511因干涉無法順利離型,強制脫模有尺寸上的限制,且會造成元件變形;而,以滾動件為塑膠射出的模仁來生產(例如日本發明專利特開平5-52217號),則會有生產效率不佳及滾動件表面的潤滑油容易被刮除的問題。因此第一圖之鏈條的設計具有嚴重的缺點,需要克服。The chain used in the linear transmission element for spacing the rolling elements is as shown in the first figure. The chain is designed to connect a plurality of individual spacer blocks. The chain in the figure is a flexible connecting chain 512 of the spacer block 511. In connection, each of the rolling elements 11 is placed between the two adjacent spacer blocks 511 and the space formed by the connecting chain 512. For the connection design of the spacer block 511 and the connecting chain 512, if the spacer block 511 and the connecting chain 512 are combined in a combined manner, a large amount of manpower is required to be assembled (for example, Japanese Patent Laid-Open No. 2005-121208); The block 511 is integrally formed with the connecting chain 512. From the viewpoint of the mold design, the surface of the spacer block 511 is a concave design, so an undercut is inevitably generated during demolding, and the mold core and the spacer block 511 interfere with each other. It is impossible to smoothly disengage, forcibly releasing the mold, and it will cause deformation of the component. However, if the rolling member is produced by plastic injection of a mold (for example, Japanese Patent Laid-Open No. 5-52217), there will be production. The problem of poor efficiency and the lubricant on the surface of the rolling member is easily scraped off. Therefore, the design of the chain of the first figure has serious drawbacks that need to be overcome.
再者,第二圖為另一種線性傳動元件之鏈條61,例如日本發明專利特開2006-070958號,其線性傳動元件上設有滾動件11,該鏈條61設有複數間隔板611,各間隔板611兩側各使用一連結鏈612連結,其中相鄰的間隔板611間各可容置一個滾動件11,使滾動件11不和相鄰的滾動件(未示出)接觸而避免產生可能的摩擦及撞擊。此設計雖然具有可開模性,但是因為在間隔板611上設有圓洞613,其模具設計使用一直徑微小且長度頗長之圓柱體做為模仁,射出成型後當成品要頂出前,必須先將圓柱體狀的模仁抽離,此時就必須使用複雜的傳動機構將圓柱體導出,然而成品在冷卻收縮後會與圓柱體緊密包覆使得抽離更加困難,同時抽離的動作會造成成品變形產生毛邊,而圓柱體亦在反覆幾次的進出後會有變形的問題;其次,在射出成型中,射出壓力相當大,這麼細長之圓柱體相當容易受強大壓力導致變形或斷裂。因此第二圖之滾動件11之鏈條61的構型量產難度也是很高,同時模具開發成本昂貴且複雜。另外,此設計之滾動件11和圓洞613的內徑間也是全面接觸,而接觸區為一個封閉的圓形,且為線接觸,接觸壓力大,故油膜不易通過接觸面,而潤滑油脂也容易被刮除。因此第二圖的設計同樣會有生產效率不佳及滾動件表面的潤滑油容易被刮除的問題。Furthermore, the second figure is a chain 61 of another type of linear transmission element, such as Japanese Patent Laid-Open No. 2006-070958, the linear transmission element is provided with a rolling member 11, which is provided with a plurality of spacer plates 611, each of which is spaced apart. Each of the two sides of the plate 611 is connected by a connecting chain 612, wherein each of the adjacent partitioning plates 611 can accommodate a rolling member 11 so that the rolling member 11 does not contact adjacent rolling members (not shown) to avoid the possibility of occurrence. Friction and impact. Although the design has mold-opening property, since the circular hole 613 is provided on the partition plate 611, the mold design uses a cylinder having a small diameter and a long length as a mold core, and before the product is to be ejected after injection molding, The cylindrical die must be removed first. At this point, the cylinder must be exported using a complicated transmission mechanism. However, the finished product will be tightly wrapped with the cylinder after cooling and shrinking, making the extraction more difficult and the pulling action. It will cause the finished product to deform and produce burrs, and the cylinder will also have deformation after several times of in and out. Secondly, in the injection molding, the injection pressure is quite large, and such a slender cylinder is quite susceptible to deformation or breakage caused by strong pressure. . Therefore, the configuration of the chain 61 of the rolling member 11 of the second figure is also difficult to mass-produce, and the mold development cost is expensive and complicated. In addition, the design of the rolling member 11 and the inner diameter of the round hole 613 is also in full contact, and the contact area is a closed circular shape, and the line contact, the contact pressure is large, so the oil film is not easy to pass the contact surface, and the lubricating grease is also Easy to be scraped off. Therefore, the design of the second figure also has the problem that the production efficiency is poor and the lubricating oil on the surface of the rolling member is easily scraped off.
另,上述滾動件11於線性傳動元件中沿著線性的軌道滾動時,負荷區域111定義為該滾動件11上與滾動軌道有接觸的區域,概呈一環狀的區域(如第一圖及第二圖滾動件表面斜線部分)。因為該負荷區域111與軌道接觸,且具有相當大的壓力存在於滾動件與軌道之間(尤其是線性傳動元件受外力時),故此負荷區域111勢必需要充分的潤滑油來潤滑,才能避免滾動件11表面或軌道產生磨耗;如果潤滑不足,將使線性傳動元件之精度降低或壽命縮短的問題產生,嚴重則造成線性傳動元件損壞。然而,由於負荷區域111持續和軌道續接觸,其上的潤滑油不斷被擠壓而被排擠到負荷區域111兩側的區域。故使滾動件11表面在負荷區域111以外的區域是有潤滑油附著的,而此區域其實並不需要潤滑;但在真正需要潤滑的環狀的負荷區域111表面反而大部份的潤滑油在滾動一小段時間後即被移除,而使潤滑效果不良。此外,以上兩種鏈條之間隔塊511或間隔板611與滾動件11為面接觸或環型接觸,故當滾動件11滾動時,滾動件與軌道接觸的負荷區域111上所附著的潤滑油會被間隔塊511或間隔板611刮除,而造成滾動件與軌道接觸的負荷區域111無法沾附潤滑油,相對的滾動件及軌道表面磨耗的問題也隨之發生。更為甚者,有些線性傳動元件的使用條件十分特殊,係在極短行程下反覆運動,例如一般內孔研磨及鑽床的鑿鑽動作等,此時滾動件11的相同區域反覆受到擠壓,表面的潤滑油將過於稀薄而使不正常磨耗嚴重增加。先前技術之線性傳動元件之鏈條實有改良精進之必要。In addition, when the rolling member 11 is rolled along a linear track in the linear transmission element, the load region 111 is defined as an area on the rolling member 11 that is in contact with the rolling track, and is generally an annular region (such as the first figure and The second figure is the diagonal part of the surface of the rolling element). Since the load region 111 is in contact with the rail and a considerable pressure is present between the rolling element and the rail (especially when the linear transmission element is subjected to an external force), the load region 111 necessarily requires sufficient lubricating oil to be lubricated to avoid rolling. The surface or track of the piece 11 is worn; if the lubrication is insufficient, the accuracy of the linear transmission element is reduced or the life is shortened, and the linear transmission element is seriously damaged. However, since the load region 111 continues to contact the track, the lubricating oil thereon is continuously squeezed to be displaced to the regions on both sides of the load region 111. Therefore, the surface of the rolling member 11 outside the load region 111 is adhered to the lubricating oil, and the region does not need lubrication. However, on the surface of the annular load region 111 where lubrication is really required, most of the lubricating oil is After a short period of rolling, it is removed, resulting in poor lubrication. In addition, the spacer block 511 or the spacer plate 611 of the above two types of chains are in surface contact or ring-shaped contact with the rolling member 11, so that when the rolling member 11 rolls, the lubricating oil attached to the load region 111 where the rolling member contacts the rail will The scraping portion 511 or the partitioning plate 611 is scraped off, and the load region 111 causing the rolling member to contact the rail is not able to adhere to the lubricating oil, and the problem of the relative rolling member and the rail surface abrasion is also caused. What's more, some linear transmission components are very special in use, and they are repeatedly moved under extremely short strokes, such as general bore grinding and drilling operations of the drilling machine. At this time, the same area of the rolling member 11 is repeatedly squeezed. The surface lubricant will be too thin to cause an abnormal increase in abnormal wear. The chain of prior art linear transmission components is necessary for improved improvement.
而在正常的潤滑油供應狀態下,為何滾動件11的表面的潤滑油過於稀薄而不正常磨耗?此讓線性傳動元件的設計者與使用者一直找不到為何會使滾動件及軌道表面產生磨耗的真正原因。而此亦為本發明人經過多次試驗才驚覺發現的,而為了解決此問題本發明人藉由後述之技術的說明,已能完整的克服上述習知技術的問題。In the normal lubricating oil supply state, why is the lubricating oil on the surface of the rolling member 11 too thin and not worn properly? This has made the designers and users of linear transmission components unable to find the real reason why the rolling parts and the track surface are worn. This has been discovered by the inventors after many trials, and in order to solve the problem, the inventors have completely overcome the problems of the above-mentioned prior art by the description of the technique described later.
基於上述習知技術之問題點,本發明人經過研究改良後,終有確能達成以下發明之目的之發明誕生。Based on the problems of the above-mentioned conventional techniques, the inventors of the present invention have succeeded in research and development, and the inventions which can achieve the object of the following inventions are finally born.

The patent scope is subject to any restrictions.
請參閱第三圖至第九圖所示,本發明係為一種具鏈條之線性傳動元件,其上具有長軸1、移動體2、滾動件5及鏈條4等。Referring to the third to ninth drawings, the present invention is a linear transmission element having a chain having a long axis 1, a moving body 2, a rolling member 5, a chain 4, and the like.
其中之長軸1,呈長條狀,其外表面上設有滾動溝11,滾動溝11的剖面輪廓大約近似於滾動件5之輪廓,以方便滾動件5可於其上滾動。滾動件5如果為一滾珠,則輪廓概呈半圓形,而滾動件5如果為一滾柱,則輪廓概呈一V字形。第三圖中之實施例是一線性滑軌,其長軸1的截面呈長方形,且滾動溝11呈一直線;但是對於一滾珠螺桿(未示出),其長軸1的截面呈圓形,且滾動溝11呈一螺旋線。The long axis 1 is elongated and has a rolling groove 11 on its outer surface. The cross-sectional profile of the rolling groove 11 is approximately similar to the contour of the rolling member 5 to facilitate rolling of the rolling member 5 thereon. If the rolling member 5 is a ball, the outline is semi-circular, and if the rolling member 5 is a roller, the outline is a V-shape. The embodiment in the third figure is a linear slide having a long axis 1 having a rectangular cross section and a rolling groove 11 in a straight line; but for a ball screw (not shown), the long axis 1 has a circular cross section. And the rolling groove 11 has a spiral.
移動體2,係套設於長軸1上;移動體2可分隔成一移動本體20和其兩側之轉向元件21(第三圖)共三件組合,以利說明及方便製造,但實務上三者可以為一體之結構。移動體2上設有相對該滾動溝11之滾動槽202,實施例中之滾動槽202係設置於移動本體20上,其中之滾動槽202為剖面輪廓相似於滾動溝11之結構,只是為了方便說明上的區別,特別將長軸1之上的稱為滾動溝11,而將移動塊2之上的稱為滾動槽202;該滾動溝11及滾動槽202相對構成一負荷路徑90(第四圖),即在此區域中,滾動體5可承受來自滾動溝11及滾動槽202間之負荷,而且移動體2可相對於該長軸1往復運行。也就是當移動體2受外力時,滾動體5夾在移動體2和長軸1之間,而對移動體2及長軸1提供一平衡掉外力的反作用力。在該移動本體20上,可以另設有供滾動件5通過之迴流孔201,例如第四圖所示,迴流孔201係貫穿移動本體20兩端面之孔。第三圖中之實施例是一線性滑軌,其滾動槽202呈一直線;但是對於一滾珠螺桿(未示出),其滾動槽202呈一螺旋線。The moving body 2 is sleeved on the long axis 1; the moving body 2 can be divided into a moving body 20 and the steering elements 21 (the third figure) on both sides thereof to form a combination of three pieces for convenience of description and convenient manufacture, but in practice The three can be a one-piece structure. The moving body 2 is provided with a rolling groove 202 opposite to the rolling groove 11. In the embodiment, the rolling groove 202 is disposed on the moving body 20, wherein the rolling groove 202 has a cross-sectional profile similar to that of the rolling groove 11, just for convenience. The difference in the description is particularly referred to as the rolling groove 11 above the long axis 1 and the rolling groove 202 above the moving block 2; the rolling groove 11 and the rolling groove 202 constitute a load path 90 (fourth In this region, the rolling bodies 5 can withstand the load from the rolling grooves 11 and the rolling grooves 202, and the moving body 2 can reciprocate relative to the long axis 1. That is, when the moving body 2 is subjected to an external force, the rolling body 5 is sandwiched between the moving body 2 and the long axis 1, and provides a reaction force for balancing the external force to the moving body 2 and the long axis 1. On the moving body 20, a return hole 201 through which the rolling member 5 passes may be further provided. For example, as shown in the fourth figure, the return hole 201 penetrates the hole of the both end faces of the moving body 20. The embodiment in the third figure is a linear slide having a rolling groove 202 in a straight line; however, for a ball screw (not shown), the rolling groove 202 is in a spiral.
轉向元件21附著在移動本體20之兩側,其隨移動本體20一起移動,故移動本體20和其兩側之轉向元件21是共同移動者,本發明將移動本體20和其兩側之轉向元件21合稱為移動體2。轉向元件21上設有一轉向路徑211,該轉向路徑211兩端係分別連接該迴流孔201與該負荷路徑90而構成一無限循環路徑,其中之轉向路徑211接續到迴流孔201再接續到另一轉向元件之上的轉向路徑(在第四圖未示出)稱為迴流路徑A,其係用以使負荷路徑90中的滾動件5接續運動而達成無限循環路徑者。另外,有些形式的線性傳動元件的迴流路徑是一體成型者,並不易將迴流路徑A明確區隔成迴流孔201及轉向路徑211,故該移動體2是否有迴流孔201為非必要特徵。如上所述,負荷路徑90之兩端分別接續迴流路徑A之兩端而形成一無限循環路徑,使滾動件5可於其間無限循環運動。The steering member 21 is attached to both sides of the moving body 20, and moves with the moving body 20, so that the moving body 20 and the steering elements 21 on both sides thereof are co-movers, and the present invention moves the body 20 and the steering elements on both sides thereof. 21 is collectively referred to as mobile body 2. The steering member 21 is provided with a steering path 211. The two ends of the steering path 211 are respectively connected to the return hole 201 and the load path 90 to form an infinite loop path. The steering path 211 is connected to the return hole 201 and then connected to the other. The steering path above the steering element (not shown in the fourth figure) is referred to as the return path A, which is used to cause the rolling elements 5 in the load path 90 to continue to move to achieve an infinite loop path. In addition, some types of linear transmission elements have a return path that is integrally formed, and it is not easy to clearly separate the return path A into the return hole 201 and the steering path 211. Therefore, whether or not the moving body 2 has the return hole 201 is an unnecessary feature. As described above, both ends of the load path 90 are respectively connected to both ends of the return path A to form an infinite loop path, so that the rolling member 5 can be infinitely cyclically moved therebetween.
複數個滾動件5,係容設於該無限循環路徑中,於該無限循環路徑中運動,並使該移動體5可相對於該長軸1往復運行。請參閱第四圖,該滾動件5在該迴流路徑A中不和該滾動溝11及該滾動槽202接觸,而在該負荷路徑90中分別和該滾動溝11及該滾動槽202接觸而可承受負荷。而由第六圖、第八圖及第九圖配合,可顯示滾動件5在滾動溝11及滾動槽202之間滾動,滾動件5滾動時的接觸軌跡概呈一個圓環狀的區域,稱為負荷區域51。A plurality of rolling elements 5 are accommodated in the infinite loop path, move in the infinite loop path, and allow the moving body 5 to reciprocate relative to the long axis 1. Referring to the fourth figure, the rolling member 5 does not contact the rolling groove 11 and the rolling groove 202 in the return path A, and is in contact with the rolling groove 11 and the rolling groove 202 in the load path 90, respectively. Bear the load. When the sixth figure, the eighth figure and the ninth figure are matched, the rolling element 5 can be displayed to scroll between the rolling groove 11 and the rolling groove 202, and the contact trajectory when the rolling element 5 rolls is an annular area. It is the load area 51.
一鏈條4,係容設於該無限循環路徑中,包含至少一長條狀撓性之連結部41及複數個間隔部42,該連結部41將該間隔部42固定連結呈等間隔排列,相鄰間隔部間形成一容置區43以容置該滾動件5;連結部41雖可以只有一條,但是為使鏈條4的連結性最佳,連結部41可設計成兩條,並對稱設置於各間隔部42之兩側。請參閱第五圖,該間隔部42包含一連接件421及兩保持件422,保持件422和該滾動件5之接觸區即形成一呈圓孤狀之接觸區TO(第十圖)。該連接件421係呈薄板狀,該連接件421之厚度係小於該保持件422之厚度,而該連接件421可以有多種設計構型,例如:波浪板狀、圓形板狀、條狀及不規格板狀等,而本實施例為一個切除兩邊的圓形薄平板,只要兩保持件422之間具有小於該保持件422之厚度的構件而將兩保持件422相互連接者,即為具有連接部421,其連接件421外緣係與兩保持件422連接,而使同一間隔部42之兩個保持件422間相互連接,並且因為連接件421為薄板狀,故可彎曲性佳,兩保持件422之間呈可撓性,可以配合滾動件5於其間無限循環運動的需要來變形。A chain 4 is disposed in the infinite loop path and includes at least one long flexible connecting portion 41 and a plurality of spaced portions 42. The connecting portion 41 is fixedly connected at equal intervals. An accommodating area 43 is formed between the adjacent partitions to accommodate the rolling element 5; although there may be only one connecting part 41, in order to optimize the connection of the chain 4, the connecting part 41 may be designed in two and symmetrically disposed on Both sides of each spacer 42. Referring to the fifth figure, the spacer 42 includes a connecting member 421 and two holding members 422. The contact area between the holding member 422 and the rolling member 5 forms a contact area TO (the tenth figure) in a circular shape. The connecting member 421 is in the form of a thin plate. The thickness of the connecting member 421 is smaller than the thickness of the holding member 422. The connecting member 421 can have various design configurations, such as a wave plate shape, a circular plate shape, a strip shape, and The plate is not shaped, and the embodiment is a circular thin plate which cuts both sides. As long as the two holding members 422 have a member smaller than the thickness of the holding member 422 and the two holding members 422 are connected to each other, The connecting portion 421 has an outer edge of the connecting member 421 connected to the two holding members 422, and connects the two holding members 422 of the same partition portion 42 to each other, and because the connecting member 421 has a thin plate shape, the bending property is good, and two The retainers 422 are flexible and can be deformed in response to the need for the rolling elements 5 to move infinitely in between.
參閱第七圖及第十圖所示,其中該滾動件5和相鄰間隔部42之接觸區T0包含兩個不相互連接之呈圓孤狀的區域,因為兩圓孤不相互連接,故兩圓孤的圓心角總和必然小於360度,平均分配的結果,即每一圓孤的圓心角YU小於180度,且其較佳的設計是該圓孤之圓心角YU約等於90度(即四分之一圓,參見第十圖),以使接觸區TO可以導引最大範圍的區域間的潤滑油,並且潤滑油係被導引到滾動件5的負荷區域51。另請參閱第七圖所示,該保持件422和該滾動件5之接觸區TO設計為非凹面,使該保持件422之表面不和該滾動件5全面接觸且接觸點呈一楔型以利動液壓力潤滑。在第七圖中,保持件422的外表面為一圓柱面,即一凸圓孤面,因為滾動件5的滾動面也是凸曲面,故滾動件5相對於保持件422間滑動(非滾動)時,油膜厚度由大而逐漸變小而產生動液壓力潤滑的效果,使滾動件5和該保持件422之表面滑動摩擦後,該滾動件5表面仍可保有一層薄薄的油膜。為達保持件422的外表面,保持件422的外表面可以設計成非凹曲面或是比滾動件5的輪廓曲率半徑還要大的凹表面,其中之非凹表面包含凸曲面及平面,當保持件422的外表面愈接近於和滾動件5的輪廓相近時,製造的控制愈需要精準,故以非凹曲面的製造穩定性較佳。Referring to the seventh and tenth drawings, wherein the contact portion T0 of the rolling member 5 and the adjacent spacer portion 42 includes two regions that are not connected to each other in a circular shape, because the two circles are not connected to each other, so two The sum of the central angles of the round orphans must be less than 360 degrees, and the result of the average distribution, that is, the central angle YU of each round is less than 180 degrees, and the preferred design is that the central angle YU of the round is equal to 90 degrees (ie, four points) One of the circles, see the tenth figure), so that the contact zone TO can guide the lubricating oil between the widest range of regions, and the lubricating oil is guided to the load region 51 of the rolling member 5. Referring to the seventh figure, the contact area TO of the holding member 422 and the rolling member 5 is designed to be non-concave, so that the surface of the holding member 422 is not in full contact with the rolling member 5 and the contact point is wedge-shaped. Liquefied fluid pressure lubrication. In the seventh figure, the outer surface of the retaining member 422 is a cylindrical surface, that is, a convex orphaned surface. Since the rolling surface of the rolling member 5 is also a convex curved surface, the rolling member 5 slides relative to the retaining member 422 (non-rolling). When the oil film thickness is large and gradually becomes smaller, the effect of the hydrodynamic pressure lubrication is generated, and after the sliding member 5 and the surface of the holding member 422 are slidably rubbed, the surface of the rolling member 5 can still retain a thin oil film. To reach the outer surface of the holder 422, the outer surface of the holder 422 may be designed as a non-concave curved surface or a concave surface larger than the contour radius of curvature of the rolling member 5, wherein the non-concave surface includes a convex curved surface and a plane, when The closer the outer surface of the holder 422 is to the contour of the rolling member 5, the more precise the manufacturing control is, so that the manufacturing stability with a non-concave curved surface is better.
定義沿者長條狀撓性之連結部41的長軸方向為軸方向X(第八圖);沿著兩連結部41的長軸方向所構成的曲面定義為導引面E(第九圖);中心面52(第九圖)係定義為通過各間隔部42之中心,且垂直(即正交)於導引面E之曲面。本發明為了降低模具的設計成本,及簡化模具的結構,該鏈條4之模具只需藉由上下模具的設計即可將該鏈條4射出成型,其模具係沿著導引面E分模,其各間隔部42之兩保持件422位於中心面52的兩側,並且分別設置於導引面E之上下兩側,使各間隔部42之兩保持件422為交錯設置(即分別位於第一、三象限或第二、四象限),於開模時不會產生倒勾而破壞鏈條4本體,且不須於模具中設置滑塊之結構大幅降低設計成本;且本發明為了讓鏈條4更容易脫模,藉由在保持件422之端面4221與中心面52間設計一夾角Q(該夾角Q係為1至7度之間為最佳),在第九圖中,該夾角Q係由導引面E向外擴張,可讓鏈條4於脫模時更容易而不會產生干涉,鏈條4表面也會較為平滑,而鏈條4表面平滑,於線性傳動元件之無限循環路徑中運行就不會與無限循環路徑產生干涉,使鏈條4運行更為順暢。The long axis direction defining the long flexible connecting portion 41 is the axial direction X (eighth view); the curved surface formed along the long axis direction of the two connecting portions 41 is defined as the guiding surface E (ninth drawing) The center plane 52 (the ninth diagram) is defined as a curved surface that passes through the center of each of the partitions 42 and is perpendicular (ie, orthogonal) to the guide surface E. In order to reduce the design cost of the mold and simplify the structure of the mold, the mold of the chain 4 can be injection molded by the design of the upper and lower molds, and the mold is divided along the guiding surface E. The two holding members 422 of the spacers 42 are located on both sides of the central surface 52, and are respectively disposed on the upper and lower sides of the guiding surface E, so that the two holding members 422 of the spacers 42 are staggered (ie, respectively located at the first, Three quadrants or the second and fourth quadrants, the main body of the chain 4 is not broken when the mold is opened, and the structure of the slider is not required to be provided in the mold, and the design cost is greatly reduced; and the present invention makes the chain 4 easier. Demolding, by designing an angle Q between the end surface 4221 of the holder 422 and the center surface 52 (the angle Q is preferably between 1 and 7 degrees), in the ninth figure, the angle Q is guided by The outward expansion of the lead surface E allows the chain 4 to be easier to release without interference, the surface of the chain 4 is smoother, and the surface of the chain 4 is smooth, and it does not operate in the infinite loop path of the linear transmission element. Interference with the infinite loop path to make the chain 4 run more smoothly
另,請特別參閱第四圖、第八圖、第九圖及第十圖所示,第四圖係為鏈條於無限循環路徑運行狀態圖;第八至十圖分別為裝有滾動件5之鏈條4的上視圖及端視圖。由第八圖的局部放大圖中可以得知,該連接件421沿著軸方向X的端面4211係與該滾動件5具有一第一間隙T,該第一間隙T可以使潤滑油無阻礙的通過。In addition, please refer to the fourth, eighth, ninth and tenth drawings in particular, the fourth diagram is the running state diagram of the chain in the infinite loop path; the eighth to tenth diagrams are respectively equipped with the rolling elements 5 Top and end views of the chain 4. It can be seen from the partial enlarged view of the eighth figure that the end surface 4211 of the connecting member 421 along the axial direction X has a first gap T with the rolling member 5, and the first gap T can make the lubricating oil unobstructed. by.
另外,請參閱第十圖所示,該滾動件5為一球體,其與保持件422接觸處形成一圓弧狀之接觸區TO,沿著呈圓孤狀之該接觸區TO之內側形成一潤滑油之通道G。在滾動件5以第十圖之水平線為軸心旋轉時,滾動件5表面上之負荷區域51呈一圓環狀(如斜線部分)。從第十圖來看,當滾動件5係由下向上旋轉時,滾動件5表面上的潤滑油由下向上移動,而形成潤滑油通道G1、G2及G3等,潤滑油附著於滾動件5之表面,而向上運動後,因為接近於上側的圓弧狀之接觸區TO時,潤滑油通道G1、G2及G3向右偏轉而到達(銜接)滾動件5表面上之負荷區域51;故,潤滑油通道G1、G2及G3可將滾動件5表面(左側)上之非負荷區負荷的潤滑油導引到負荷區域51,使負荷區域51可以得到充分的潤滑;反過來,當滾動件5係由上向下旋轉時,滾動件5表面上的潤滑油由上向下移動,而形成潤滑油通道G4、G5及G6等,潤滑油附著於滾動件5之表面,而向下運動後,因為接近於下側的圓弧狀之接觸區TO,潤滑油通道G4、G5及G6向左偏轉而到達(銜接)滾動件5表面上之負荷區域51;故,潤滑油通道G4、G5及G6將滾動件5表面(右側)上之非負荷區負荷的潤滑油導引到負荷區域51,使負荷區域51可以得到充分的潤滑;不管滾動件正向或反向滾動都可有效潤滑滾動件5表面上之負荷區域51,使滾動件5得到充分的潤滑。其中,該潤滑油之通道G係包含各潤滑油通道G1、G2、G3、G4、G5及G6等,第十圖中之箭頭表示潤滑油通道G之流向,各潤滑油通道概呈C字型,而潤滑油通道G流經該滾動件5之負荷區域51(如斜線部分)。該負荷區域51於容置區43中轉動時時,可藉由該潤滑油之通道G補充足夠的潤滑油來潤滑,而不會刮除滾動件5之負荷區域51所附著的潤滑油,使潤滑油於滾動件5上形成一完整的潤滑油膜,以達到降低該滾動溝11、滾動槽22及滾動件5三者之間摩擦力的目的。故本發明已改善習知技術的問題點,使滾動件5之負荷區域51能得到充足的潤滑,以維持線性傳動元件之定位精度及延長線性傳動元件的使用壽命。In addition, as shown in the tenth figure, the rolling member 5 is a ball, and an arc-shaped contact area TO is formed in contact with the holder 422, and a contact area TO is formed along the inner side of the contact area TO in a circular shape. The passage G of the lubricating oil. When the rolling member 5 is rotated about the horizontal line of the tenth graph, the load region 51 on the surface of the rolling member 5 has an annular shape (e.g., a hatched portion). As seen from the tenth diagram, when the rolling member 5 is rotated from the bottom to the top, the lubricating oil on the surface of the rolling member 5 moves from the bottom to the top to form the lubricating oil passages G1, G2, G3, etc., and the lubricating oil adheres to the rolling member 5 After the upward movement, the lubricating oil passages G1, G2, and G3 are deflected to the right to reach (engage) the load region 51 on the surface of the rolling member 5 because it is close to the arc-shaped contact region TO on the upper side; The lubricating oil passages G1, G2 and G3 can guide the lubricating oil in the non-load region on the surface (left side) of the rolling member 5 to the load region 51, so that the load region 51 can be sufficiently lubricated; in turn, when the rolling member 5 When rotating from top to bottom, the lubricating oil on the surface of the rolling member 5 moves from top to bottom to form lubricating oil passages G4, G5, G6, etc., and the lubricating oil adheres to the surface of the rolling member 5, and after moving downward, Because of the arc-shaped contact area TO close to the lower side, the lubricating oil passages G4, G5 and G6 are deflected to the left to reach (engage) the load region 51 on the surface of the rolling member 5; therefore, the lubricating oil passages G4, G5 and G6 Guide the lubricating oil in the non-load zone load on the surface (right side) of the rolling member 5 to the load Field 51, the load region 51 can be sufficiently lubricated; regardless of the rolling member rolling forward or reverse loading area 51 can be effectively lubricating the rolling member 5 on the surface, the rolling member 5 fully lubricated. Wherein, the passage G of the lubricating oil includes each lubricating oil passages G1, G2, G3, G4, G5, and G6, and the arrow in the tenth diagram indicates the flow direction of the lubricating oil passage G, and each lubricating oil passage is C-shaped. And the lubricating oil passage G flows through the load region 51 (such as a diagonal portion) of the rolling member 5. When the load region 51 is rotated in the accommodating region 43, the lubricating oil channel G can be supplemented with sufficient lubricating oil to lubricate without scraping off the lubricating oil attached to the load region 51 of the rolling member 5. The lubricating oil forms a complete lubricating oil film on the rolling member 5 to achieve the purpose of reducing the friction between the rolling groove 11, the rolling groove 22 and the rolling member 5. Therefore, the present invention has improved the problems of the prior art, so that the load region 51 of the rolling member 5 can be sufficiently lubricated to maintain the positioning accuracy of the linear transmission member and prolong the service life of the linear transmission member.
值得一提的是,本實施例中之鏈條之兩保持件422係分別設置於該滾動件5之該負荷區域51之兩側,使該負荷區域51之兩側皆有該潤滑油通道G,以導引該滾動件5之該負荷區域51兩側之潤滑油;雖然,該間隔部42只設置一保持件422亦可實施,但會降低對於滾動件5的潤滑效果。It is to be noted that the two holding members 422 of the chain in the embodiment are respectively disposed on the two sides of the load region 51 of the rolling member 5, so that the lubricating oil passages G are provided on both sides of the load region 51. To guide the lubricating oil on both sides of the load region 51 of the rolling member 5; although the spacer portion 42 is only provided with a retaining member 422, the lubricating effect on the rolling member 5 is reduced.
另外,為了因應有些滾動件5與負荷路徑90接觸的面積較大,相對的滾動件5之負荷區域51也較大,故滾動件5與間隔部42之間也需要有較大的潤滑油之通道G,然而,本發明可藉由該保持件422的端面4221與該連接件421之交點4222與該滾動件5之中心面52偏移一第二間隙D,即可加大潤滑油之通道G,相對也符合前述滾動件的需求。In addition, in order to ensure that the area of contact between the rolling elements 5 and the load path 90 is large, the load area 51 of the opposing rolling elements 5 is also large, so that a large lubricating oil is required between the rolling elements 5 and the spacing portion 42. The channel G, however, the invention can increase the passage of the lubricating oil by offsetting the intersection 4222 of the holder 422 with the intersection 4222 of the holder 421 and the center surface 52 of the rolling member 5 by a second gap D. G, relatively in line with the needs of the aforementioned rolling elements.
綜所上述,本發明之鏈條確實完整的改善習知技術無法突破的問題點,如:大幅度的提升鏈條運行的順暢度、潤滑效果、維持線性傳動元件之精度、延長線性傳動元件之壽命、降低模具設計成本及可大量生產鏈條等。所以本發明之『具有產業之可利用性』應已毋庸置疑,除此之外,在本案實施例所揭露出的特徵技術,於申請之前並未曾見於諸刊物,亦未曾被公開使用,不但具有如上所述功效增進之事實,更具有不可輕忽的附加功效,是故,本發明的『新穎性』以及『進步性』都已符合專利法規,爰依法提出發明專利之申請,祈請惠予審查並早日賜准專利,實感德便。In view of the above, the chain of the present invention does not completely improve the problems that the prior art cannot break through, such as: greatly improving the smoothness of the chain operation, lubricating effect, maintaining the precision of the linear transmission component, prolonging the life of the linear transmission component, Reduce mold design costs and mass production of chains. Therefore, the "industry availability" of the present invention should be unquestionable. In addition, the feature technology disclosed in the embodiment of the present invention has not been seen in publications before the application, nor has it been publicly used, and has not only As described above, the fact that the effect is enhanced is more indispensable, and therefore, the "novelty" and "progressiveness" of the present invention are in compliance with the patent regulations, and the application for the invention patent is filed according to law, and the application for review is prayed for.
