線性滑軌滾珠保持器 Linear slide ball cage

本發明涉及一種使用於線性滑軌裝置,尤指一種可將多數個滾動元件保持於其間的線性滑軌滾珠保持器。 The present invention relates to a linear slide rail device, and more particularly to a linear slide ball cage that holds a plurality of rolling elements therebetween.

線性滑軌滾珠保持器是一種用來保持線性滑軌內各滾動元件的裝置,可使各滾動元件之間維持一定的距離,並且避免滾動元件之間產生碰撞,藉此使滾珠達到良好的滾動狀態以及延長使用壽命。 The linear slide ball retainer is a device for holding the rolling elements in the linear slide, which can maintain a certain distance between the rolling elements and avoid collision between the rolling elements, thereby achieving good rolling of the balls. Status and extended life.

現有的線性滑軌滾珠保持器,請參看日本發明專利案第2607993號所揭露的「滾珠鏈及直線運動引導裝置」(以下稱參考文獻1),其中,如圖2所示,參考文獻1於兩側設有平行的兩鏈帶,於兩鏈帶之間間隔地容設有複數個滾珠,於各滾珠之間設置一間隔體,各間隔體兩側分別朝滾珠方向形成弧狀凹面,透過該凹面接觸滾珠,用以保持滾珠定位。 For the conventional linear slide ball cage, please refer to "Ball Chain and Linear Motion Guide Device" (hereinafter referred to as Reference 1) disclosed in Japanese Patent Application No. 2607993, wherein, as shown in FIG. 2, Reference 1 Two parallel belts are arranged on both sides, and a plurality of balls are arranged at intervals between the two chain belts, and a spacer is arranged between the balls, and the two sides of each spacer form an arc-shaped concave surface in the direction of the balls, The concave surface contacts the ball to maintain ball positioning.

然而,參考文獻1所述的間隔體雖然可利用凹面與滾珠接觸來保持定位,但間隔體的凹面與滾珠的接觸屬於面接觸,因此,不僅接觸面會產生較大的摩擦力之外,同時接觸面上亦不容易儲存潤滑油,甚至會刮除滾珠上的潤滑油,而容易造成滾珠滾動不順暢,以及產生噪音等 問題。 However, although the spacer described in Reference 1 can be held in contact with the ball by the concave surface, the contact of the concave surface of the spacer with the ball is in surface contact, and therefore, not only the contact surface generates a large frictional force, but also It is also not easy to store lubricating oil on the contact surface, and even scrape off the lubricating oil on the ball, which may cause the ball to roll unsmoothly, and generate noise, etc. problem.

另請參看美國發明專利案第6364086號所揭露的保持器(以下稱參考文獻2),其中,如圖1所示,該保持器的左右兩側設有平行的兩鏈帶,於兩鏈帶之間間隔地容設有複數個滾珠,於複數個滾珠之間則分別設有一間隔體,各間隔體為兩組背向設置的止擋組件,該止擋組件包含有兩左右間隔設置的勾爪部,各勾爪部朝滾珠方向呈弧狀並分別朝上下延伸,各勾爪部形成有一凹面供滾珠接觸抵靠,而可將滾珠保持定位。 See also the retainer disclosed in U.S. Patent No. 6,364,084 (hereinafter referred to as reference 2), wherein, as shown in FIG. 1, the two left and right sides of the retainer are provided with two parallel chain belts. A plurality of balls are arranged at intervals, and a spacer is respectively disposed between the plurality of balls, and each of the spacers is two sets of stop assemblies disposed opposite to each other, and the stop assembly comprises two hooks arranged at intervals In the claw portion, each of the hook portions is curved in the direction of the balls and extends upward and downward respectively, and each of the hook portions is formed with a concave surface for the balls to contact against, and the balls can be positioned.

又,如參考文獻2的圖3至圖5所示,保持器的間隔體分別具有背向設置有兩止擋組件,各止擋組件分別呈圓盤狀,並且於兩側分別朝滾珠方向形成凹面,藉由凹面接觸滾珠,而可將滾珠保持定位。如圖6所示的間隔體則是呈一體成形的塊體,並於塊體朝滾珠方向分別形成凹面,以凹面與滾珠接觸抵靠,而使滾珠保持定位。 Moreover, as shown in FIG. 3 to FIG. 5 of Reference 2, the spacers of the retainer respectively have two stop assemblies disposed in the back direction, and each of the stop assemblies has a disk shape and is formed on the two sides toward the balls. The concave surface keeps the balls in position by the concave contact of the balls. The spacer shown in Fig. 6 is an integrally formed block, and a concave surface is formed in the block direction in the direction of the balls, and the concave surface is in contact with the balls to keep the balls in position.

由於參考文獻2的各實施例皆以間隔體的凹面與滾珠接觸,因此,同樣屬於面接觸的形態,而有接觸面積大、摩擦力增加,以及接觸面上不容易儲存潤滑油的缺點。即便是如圖1所示的採用勾爪部的設計,雖然可縮小間隔體與滾珠的接觸面積,但仍然屬於面接觸的範疇,而無法擺脫接觸面上無法儲存潤滑油的問題,對於增進滾珠滾動的順暢度上,仍無法有效地提升。 Since each of the embodiments of the reference 2 is in contact with the balls with the concave surface of the spacer, it is also in the form of surface contact, and has a large contact area, an increased frictional force, and a disadvantage that the lubricating oil is not easily stored on the contact surface. Even if the design of the hook portion as shown in Fig. 1 can reduce the contact area between the spacer and the ball, it still belongs to the category of surface contact, and it is impossible to get rid of the problem that the lubricating oil cannot be stored on the contact surface, and the ball is improved. The smoothness of scrolling still cannot be effectively improved.

為解決現有線性滑軌滾珠保持器會有摩擦力大以及潤滑油效果不佳的缺點,本發明係提供一種線性滑軌 滾珠保持器,可使間隔體以三點接觸包覆方式來保持滾珠定位,可大幅縮小間隔體與滾珠的接觸面積,同時提供儲存潤滑油的空間,有效提升滾珠滾動的順暢度。 In order to solve the shortcomings of the existing linear slide ball retainer, which has large friction and poor lubricating effect, the present invention provides a linear slide rail. The ball retainer allows the spacer to maintain the ball positioning in a three-point contact wrap manner, which greatly reduces the contact area between the spacer and the ball, and provides a space for storing lubricating oil, thereby effectively improving the smoothness of the ball rolling.

所述的第一拘束部亦可呈包含兩背向設置及分別向上下兩側延伸的第一勾爪,該第二拘束部係包含兩背向設置及分別向下上兩側延伸的第二勾爪,該第一勾爪與左右相鄰的第二勾爪係呈上下交錯設置,以及該第一勾爪外側端突出於內側端形成包覆狀,向下延伸的該第二勾爪下側端突出於上側端形成包覆狀,向上延伸的該第二勾爪 上側端突出於下側端形成包覆狀。 The first restraining portion may also include a first hook that is disposed opposite to each other and extends upward and downward respectively, and the second restraining portion includes two rearwardly disposed and secondly extending downwardly from the upper and lower sides respectively a hook, the first hook and the second hook adjacent to the left and right are arranged in an up-and-down manner, and the outer end of the first hook protrudes from the inner end to form a wrap, and the second claw extends downward. The side end protrudes from the upper end to form a wrap shape, and the second claw extends upward The upper end protrudes from the lower end to form a coating.

所述的第一勾爪面與該第一凸形結構之間的段差形成一儲油空間,該第二勾爪面與該第二凸形結構之間的段差形成一儲油空間。 The step difference between the first claw surface and the first convex structure forms an oil storage space, and a step difference between the second claw surface and the second convex structure forms an oil storage space.

所述的第一凸形結構與第二凸形結構為凸肋形態,該第一凸形結構與第二凸形結構之凸肋以環狀方式排列為較佳的設置方式,亦不限制呈縱向排列方式設置。此外,所述的第一凸形結構與該第二凸形結構亦可為凸點形態。 The first convex structure and the second convex structure are in the form of ribs, and the ribs of the first convex structure and the second convex structure are arranged in an annular manner as a preferred arrangement, and are not limited to Vertical arrangement. In addition, the first convex structure and the second convex structure may also be in a bump shape.

藉由上述之技術手段,本發明的線性滑軌滾珠保持器具有下列之功效: By the above technical means, the linear slide ball cage of the present invention has the following effects:

1.點接觸減少摩擦力:由於間隔體是以凸形結構與滾珠形成點接觸,因此,間隔體與滾珠間的接觸面積可大幅縮小,有效達到減少摩擦力之目的。 1. Point contact reduces friction: Since the spacer is in contact with the ball by the convex structure, the contact area between the spacer and the ball can be greatly reduced, and the friction reducing force can be effectively achieved.

2.包覆式保持不易掉珠:由於間隔體的勾爪均呈包覆狀,且左右相鄰的勾爪採上下交錯設置,因此,各間隔體分別以三勾爪環繞包覆滾珠,可有效防止滾珠掉出。 2. The covered type is not easy to drop the beads: since the hooks of the spacer are covered, and the left and right adjacent claws are arranged in a staggered manner, each of the spacers surrounds the balls with three hooks, respectively. Effectively prevents balls from falling out.

3.含油結構充分潤滑:由於凸形結構形成於凹弧狀的勾爪面上,因此,當凸形結構接觸滾珠時,勾爪面與滾珠表面之間會產生間隙,進而形成可含油的儲油空間。此外,各儲油空間之間相互連通,潤滑油可於各儲油空間中自由流動,而達到充分且均勻地潤滑效果,使滾珠更為順暢的滾動並減少噪音。 3. The oil-containing structure is fully lubricated: since the convex structure is formed on the concave arc-shaped claw surface, when the convex structure contacts the ball, a gap is formed between the claw surface and the ball surface, thereby forming an oil-containing reservoir. Oil space. In addition, the oil storage spaces communicate with each other, and the lubricating oil can flow freely in each oil storage space to achieve a sufficient and uniform lubrication effect, so that the balls roll smoothly and reduce noise.

4.減少滾珠偏移:由於前後相鄰的間隔體於勾爪面上 所形成的凸形結構可為凸肋呈環狀排列,因此,當滾珠開始滾動時,即便滾珠滾動方向產生偏移,間隔體上呈環狀排列的凸形結構仍可將滾珠保持在中心位置,以減少滾珠的滑動偏移,以及增加滾珠的滾動效果。 4. Reduce ball offset: due to the adjacent spacers on the hook surface The convex structure formed may have annular ribs arranged in an annular shape, so that when the balls start to roll, even if the rolling direction of the balls is shifted, the convex structure arranged in a ring shape on the spacer can keep the balls in the center position. To reduce the sliding offset of the ball and increase the rolling effect of the ball.

為能詳細瞭解本發明的技術特徵及實用功效,並可依照說明書的內容來實現,玆進一步以如圖式所示的較佳實施例,詳細說明如后:請參看圖1至圖3,本發明之線性滑軌滾珠保持器的第一實施例係設有多數個以前、後面對而間隔設置 的間隔體10,以及於各間隔體10左右兩端分別結合有一連接帶20,於左右兩連接帶20與相鄰兩間隔體10之間容設有一滾珠30,其中,各間隔體10於左右兩側分別形成有一第一拘束部11,於該兩第一拘束部11之間形成有一第二拘束部12。 In order to understand the technical features and practical functions of the present invention in detail, and in accordance with the contents of the specification, the following is further illustrated in the preferred embodiment as illustrated in the following: Please refer to FIG. 1 to FIG. The first embodiment of the inventive linear slide ball cage is provided with a plurality of front and rear pairs and spaced apart The spacers 10 and the connecting strips 20 are respectively coupled to the left and right ends of the spacers 10. A ball 30 is disposed between the left and right connecting strips 20 and the adjacent spacers 10, wherein each of the spacers 10 is left and right. A first restraining portion 11 is formed on each side, and a second restraining portion 12 is formed between the two first restraining portions 11.

請再參看圖3至圖6,第一實施例中各間隔體10的第一拘束部11係包含兩背向設置且向上延伸的第一勾爪110,該第一勾爪110的肉厚由外側向內側漸縮,如圖4所示,外側的厚度T1大於內側的厚度T2,而使外側端突出於內側端形成包覆狀,於該各第一勾爪110上形成有一第一勾爪面111,該第一勾爪面111係對應滾珠30形狀呈凹弧狀,於該第一勾爪面111上形成有一弧曲狀的第一凸形結構112,本實施例之第一凸形結構112為弧曲狀設置的凸肋。 Referring to FIG. 3 to FIG. 6 again, in the first embodiment, the first restraining portion 11 of each of the spacers 10 includes two first claws 110 disposed away from the back and extending upward, and the thickness of the first claws 110 is determined by The outer side is tapered toward the inner side. As shown in FIG. 4, the outer thickness T1 is larger than the inner thickness T2, and the outer end protrudes from the inner end to form a wrap, and the first claw 110 is formed with a first claw. The first claw surface 111 has a concave arc shape corresponding to the shape of the ball 30, and an arcuate first convex structure 112 is formed on the first claw surface 111. The first convex shape of the embodiment The structure 112 is a rib provided in an arc shape.

上述第二拘束部12的兩側分別連結於該兩第一拘束部11,該第二拘束部12係包含兩背向設置且向下延伸的第二勾爪120,該第二勾爪120的肉厚由下側向上側漸縮,如圖4所示,下側厚度T3大於上側厚度T4,而使下側端突出於上側端形成包覆狀,於該第二勾爪120上形成有一第二勾爪面121,該第二勾爪面121係對應滾珠30呈凹弧狀,於該第二勾爪面121上形成有一弧曲狀的第二凸形結構122,本實施例之第二凸形結構122為弧曲狀設置的凸肋。如圖3所示,第一實施例中呈弧曲狀的兩第一凸形結構112與第二凸形結構122係以環狀方式排列設置,即該兩第一凸形結構112與第二凸形結構122分別 為一圓環狀的其中一段。 The two sides of the second restraining portion 12 are respectively coupled to the two first restraining portions 11 , and the second restraining portion 12 includes two second claws 120 disposed downwardly and downwardly extending, and the second claws 120 The thickness of the meat is gradually reduced from the lower side to the upper side. As shown in FIG. 4, the lower side thickness T3 is larger than the upper side thickness T4, and the lower side end protrudes from the upper side end to form a wrap, and the second hook 120 is formed with a first The second claw surface 121 has a concave arc shape corresponding to the ball 30, and a second convex structure 122 is formed on the second claw surface 121, which is the second embodiment. The convex structure 122 is a convex rib provided in an arc shape. As shown in FIG. 3, the two first convex structures 112 and the second convex structures 122 which are curved in the first embodiment are arranged in an annular manner, that is, the two first convex structures 112 and the second Convex structure 122 respectively It is a section of a ring.

上述連接帶20為平行的片體而分別結合於各間隔體10的第一拘束部11上,各連接帶20與各對相鄰間隔體10接鄰的內面分別形成一凹弧面,各連接帶20相對的凹弧面與各對相鄰的間隔體10之間形成一容置空間,各容置空間係呈圓球形,可供滾珠30嵌設容置。 The connecting strips 20 are parallel sheets and are respectively coupled to the first restraining portions 11 of the spacers 10, and the connecting strips 20 and the pair of adjacent spacers 10 respectively form a concave curved surface. An accommodating space is formed between the concave curved surface of the connecting strip 20 and each pair of adjacent spacers 10. The accommodating spaces are spherical and can be embedded in the ball 30.

請參照圖4與圖5,當滾珠30嵌設於容置空間時,相鄰的兩間隔體10分別以朝向滾珠30的第一勾爪110與第二勾爪120將滾珠30保持定位,各間隔體10以兩第一勾爪110上的第一凸形結構112與第二勾爪120上的第二凸形結構122與滾珠30形成三點接觸,藉此來達到保持滾珠30的效果,同時大幅縮小間隔體10與滾珠30間的接觸面積,可有效減少間隔體10與滾珠30之間的摩擦力。 Referring to FIG. 4 and FIG. 5, when the balls 30 are embedded in the accommodating space, the adjacent two spacers 10 respectively position the balls 30 with the first claws 110 and the second claws 120 facing the balls 30, respectively. The spacer 10 forms a three-point contact with the ball 30 by the first convex structure 112 on the two first claws 110 and the second convex structure 122 on the second claw 120, thereby achieving the effect of maintaining the balls 30. At the same time, the contact area between the spacer 10 and the balls 30 is greatly reduced, and the friction between the spacer 10 and the balls 30 can be effectively reduced.

由於第一勾爪110的第一凸形結構112與第二勾爪120的第二凸形結構122是以環狀方式排列設置,因此,當滾珠30開始滾動時,即便滾珠滾動方向30產生偏移,間隔體10上呈環狀排列的凸形結構112、122仍可接觸滾珠30,並且將滾珠30保持在容置空間的中心位置,達到減少滾珠30的滑動偏移,增加滾珠30滾動時的順暢度。 Since the first convex structure 112 of the first claw 110 and the second convex structure 122 of the second claw 120 are arranged in an annular manner, even when the ball 30 starts to roll, even if the ball rolling direction 30 is biased The convex structures 112, 122 arranged in a ring shape on the spacer 10 can still contact the balls 30, and the balls 30 are held at the center of the accommodating space, so as to reduce the sliding deviation of the balls 30 and increase the rolling of the balls 30. Smoothness.

此外,當滾珠30嵌設於容置空間時,兩間隔體10分別以朝向滾珠30的第一勾爪110與第二勾爪120環繞包覆滾珠30,由於該第一勾爪110的外側端突出於內側端形成包覆狀,以及該第二勾爪120的下側端突出於 上側端形成包覆狀,因此,各間隔體10形成三爪環繞包覆滾珠30的形態,藉此可有效定位滾珠30,具有防止滾珠30掉出之功效。 In addition, when the ball 30 is embedded in the accommodating space, the two spacers 10 surround the coated ball 30 with the first claw 110 and the second claw 120 facing the ball 30 respectively, due to the outer end of the first claw 110 Projecting on the inner end to form a wrap, and the lower end of the second hook 120 protrudes from The upper end is formed in a wrap shape, and therefore, each of the spacers 10 is formed in a form in which three claws surround the coated balls 30, whereby the balls 30 can be effectively positioned, and the ball 30 can be prevented from falling out.

進一步,當第一凸形結構112與第二凸形結構122接觸保持滾珠30時,由於第一勾爪面111與第二勾爪面121分別對應滾珠30呈凹弧狀,因此該第一勾爪面111與該第二勾爪面121是以環繞包覆但不接觸的方式設置在滾珠30的周圍。再者,利用突起的第一凸形結構112與第二凸形結構122接觸滾珠30形成段差,而使得第一勾爪面111與該第二勾爪面121分別與滾珠30表面之間產生間隙,而可供作儲存潤滑油的儲油空間40,使間隔體10具備含油效果,可有效增進滾珠30滑動時的順暢度。 Further, when the first convex structure 112 and the second convex structure 122 are in contact with the holding ball 30, since the first claw surface 111 and the second claw surface 121 respectively have a concave arc corresponding to the ball 30, the first hook The claw surface 111 and the second claw surface 121 are disposed around the ball 30 so as to be wrapped around but not in contact with each other. Moreover, the first convex structure 112 of the protrusion and the second convex structure 122 contact the ball 30 to form a step, so that a gap is formed between the first claw surface 111 and the second claw surface 121 and the surface of the ball 30, respectively. The oil storage space 40, which can be used for storing lubricating oil, provides the spacer 10 with an oil-containing effect, which can effectively improve the smoothness of the ball 30 when sliding.

如圖3與圖6所示,當於線性滑軌滾珠保持器注入潤滑油時,潤滑油會從各勾爪111、121的上下兩側進入滾珠30與間隔體10之間,而儲存於各勾爪111、121的儲油空間40中,當滾珠30開始滾動時,由於滾珠30周圍六個勾爪的儲油空間40都相互連通,因此可供潤滑油自由流動,達到充分且均勻的潤滑效果,可使滾珠30更順暢地滾動。 As shown in FIG. 3 and FIG. 6, when lubricating oil is injected into the linear slide ball cage, lubricating oil enters between the balls 30 and the spacer 10 from the upper and lower sides of the respective claws 111, 121, and is stored in each. In the oil storage space 40 of the claws 111, 121, when the balls 30 start to roll, since the oil storage spaces 40 of the six claws around the balls 30 are in communication with each other, the lubricating oil can be freely flowed to achieve sufficient and uniform lubrication. The effect is that the balls 30 can be rolled more smoothly.

請參照圖7所示,本發明之第二實施例結構大致與第一實施例相同,惟各間隔體10上的第一凸形結構112A與第二凸形結構122A係呈縱向設置的凸肋。 Referring to FIG. 7, the structure of the second embodiment of the present invention is substantially the same as that of the first embodiment, except that the first convex structure 112A and the second convex structure 122A on each of the spacers 10 are longitudinally disposed. .
