[Embodiment 3 5 201030251] MODE FOR CARRYING OUT THE INVENTION Hereinafter, the best mode for carrying out the invention will be described in detail based on the embodiments shown in the drawings. (First Embodiment) Fig. 1 shows a rotor holder according to a first embodiment of the present invention. This rotor holder 1 holds the ball cage of the balls 2. In other words, the plurality of balls 2 arranged at predetermined intervals are held in a series to hold the balls 2 in a state in which the balls 2 are held from front to back in the direction in which the balls are arranged, and the balls are held from the ball holding portions. The wing portion 22 in which the direction of the arrangement intersects perpendicularly intersects, and the flexible connecting portion 连结 that connects the wing portions 22 are deformed by the connecting portion 23, and the ball 2 can be held while being held by the ball holding portion 1 The alignment direction is curved. The balls 2 are rotatably held in a state in which the rotation axes of the balls 2 are parallel to each other in a state of being sandwiched between the respective ball holding portions 10. ^ ▲ Here, in the following description, as shown in the figure i, it is assumed that the perpendicular intersection coordinates of the X-ray, the γ-axis, and the z-axis perpendicular to each other cause the arrangement direction of the balls to be the X-direction, and the rotation of the balls 2 The axial direction is the γ-axis direction, and the direction in which the X-pull and the ¥-axis intersect perpendicularly is the Z-axis direction. The bead holding portion 10 is disposed every other one of the balls, and is formed of two cylindrical members having a smaller diameter from the second cooling H ball holding portion 1G than the ball diameter, and is provided on both end faces thereof for the balls. 2 is held as a sliding scale recess l〇a. The holding recess 1〇a is formed into a spherical shape of the spherical cap tube for the ball 2. #然, the shape of the ball retaining portion 1G is not limited to the circle 201030251 The X-axis of the wing 22 The width of the direction (ball arrangement direction) is set to be the same width as the width of the ball holding portion 1 in the x-axis direction, and the X-axis of the wing portion 22 is displayed as shown in the first (F) pattern. The width A1 of the direction is preferably set to be equal to or smaller than the width A0 of the ball holding portion 10 in the X-axis direction. The 'wing portion 22 has a thin plate shape, as shown in the first (F) view, and the z-axis direction (with the ball arrangement direction and the ball The thickness B1 of the direction in which the direction of the rotation axis intersects perpendicularly is smaller than the thickness B0 of the ball holding portion 10 in the Z-axis direction. Further, the thickness t of the connecting portion 23 in the Z-axis direction is smaller than the thickness Bi of the wing portion 22 in the axial direction. The position of the wing portion 22 in the Z-axis direction is offset from the center of the ball by a predetermined amount. The inner peripheral side is formed when the transition direction is formed. The connecting portion 23 is a resin member and is a linear member 3〇 of the extending material, and is integrally formed with the ball holding portion 10 and the wing portion 22. The linear member 3〇 The entire length of the rotor holder is extended along the direction X of the arrangement of the balls 2. The portion of the line member 30 is fixed integrally with each other across the wings 22, and the portion of the portion between the wings 22 is exposed. The portion of the linear member 3G is preferably circular. The cross-sectional shape is not limited to a perfect circle or an ellipse, and the shape similar to the circular shape is also included. The linear member 30 and the ball holding portion 10 and the wing are included. The part 22 is integrally formed by being inserted and formed. Regarding the bead holding part 1〇 and the wing part, an injection-formable tree moon 曰 material, for example, a poly s system, a nylon system, a poly gynecological system, or a propylene system can be used. Various fine materials such as fluororesin, etc. In particular, when the oil-containing resin is used, the oil-free linear motion guiding device can be realized. On the other hand, the linear member 3 is resin-based and extends, and the molecular key 201030251 is oriented. Extension, so the fiber between the molecules The structure and the spinning structure are not special; the technical strength is increased. The material of the ring production = Γ30 is not particularly limited, and it is preferable to use a material such as a coolant that does not swell the coolant, for example, when the line is used, Due to the swelling of the rotating body holder, when installed in the circulation path, the rotating body can be kept as small as possible, so that the number of balls that can be installed can be increased. Alternatively, a hybrid material such as a domain dimension can be selected. In the environment where the temperature is high, the linear member 30 can be used in a separate structure from the ball holding portion 22, and the resin material can be selected in a wide range, and the retainer can be realized with a long-lasting property. In the field, the linear member 3G may be made of the same resin as the ball holding portion 1G and the wing portion η. In the case of the same-resin, the linear member 3〇 and the wing portion are excellent in adhesion, and can be firmly fixed. Further, in addition to the resin system, the linear member 30 may be made of glass fiber or metal wire. Further, in the example shown in the drawing, the linear member % is placed on both sides of the ball row, and a plurality of bars may be disposed. Further, the linear member 3A is not limited to the form of a thread, but also includes a strip shape. Further, in the above embodiment, the fixing of the linear member 3 and the wing portion 22 does not require fixing, but the relative contact between the linear member 3A and the wing portion 22 is relatively moved. Fig. 2(A) is a partially cutaway perspective view showing an example of a linear motion guiding device incorporated in the rotor retainer of Fig. i as an infinite loop linear motion device. (B) is an enlarged perspective view of the ball circulation path. A partial cross-sectional view of the direction change path '(D) is a partial perspective view of the rotor holder 201030251 at the time of the conversion direction. The Λ 料 动 动 卜 卜 卜 卜 卜 卜 卜 卜 卜 卜 卜 卜 卜 卜 卜 卜 卜 卜 卜 卜 卜 卜 卜 卜 卜 卜 卜 卜 卜 卜 。 。 。 The balls 2 are held by the rotor holder 1, and are incorporated in the moving block Μ, which is the ball circulation path 53 of the rotator circulation path. The ball circulation path 53 forms an on-load ball passage 54 extending in a straight line, an unloaded ball passage ❹ 55 extending in parallel with the on-load ball passage 54, and connecting both ends of the loaded ball passage 54 and the unloaded ball passage 55. The structure of the direction switching path 56. When the moving block 52 moves in one side, the ball 2 moves while moving in the moving ball 52 in the moving direction of the moving block 52, and the ball 2 moves to the loaded ball path from the unloaded ball path 55 via the direction changing path 56. 54. At the same time, the transfer path is pushed out to the unloaded ball passage 55, and the ball holding portion 10 of the rotor holder 1 is circulated and moved in the ball circulation path 53 while maintaining a constant interval. φ Whenever the ball 2 passes the direction changing path 56, the connecting portion 23 between the wing portions 22 is repeatedly subjected to bending. In the present embodiment, since the width of the wing portion 22 in the z-axis direction is the same as the width of the ball holding portion 10, the connecting portion 23 exposed between the wing portions 22 is long and is easily bent. Therefore, the bending stress acting on the joint portion 23 can be reduced as much as possible, the fatigue strength is improved, and the durability is increased. The width of the wing portion 22 in the X-axis direction is smaller than the width of the ball holding portion 10 in the X-axis direction as shown in the first (F) diagram, and the longer the coupling portion 23 is, the more the bending stress in the direction switching path 56 is. small. In detail, the bending stress acting on the joint portion 23 is larger as the radius of curvature of the change path 56 is smaller as the direction of curvature of the change path 56 is smaller, and the thickness t of the knot portion 23 is larger. On the other hand, the smaller the radius of curvature of the direction changing path ^6 is, the smaller the thickness t of the connecting portion 23 is. Therefore, it is considered to increase the direction switching path 56, and since the size of the device is increased, the size of the direction switching path 56 is restricted. When the radius of curvature of the direction changing path 56 is constant, when the wing portion 22 is long and the connecting portion 23 is not exposed to the rotating body holder, the connecting portion 23 is shortened, so the connecting portion 23 when passing through the direction changing path 56 is used. The curvature increases and is associated with an increase in bending stress. Therefore, in the present invention, when the wing portion 22 is made smaller than the ball holding portion 10' and the connecting portion 23 is made as long as possible, the curvature of the connecting portion 23 when reaching the direction changing path 56 can be minimized as a result, and as a result, the bending stress is obtained. Zoom out. Assuming the radius of curvature of the joint portion 23, when the joint portion 23 is short, the radius of curvature is smaller than the radius of curvature of the direction change path 23. According to the present invention, if the wing portion 22 is reduced to the left and right of the ball holding portion 10, the curvature of the curved connecting portion 23 can be moderated to the radius of curvature of the direction changing path 56.
又，由於連結部23之Z軸方向之厚度t亦小於翼部22之Z 軸方向之厚度’故彎曲剛性自身小，而可縮小彎曲應力。 再者由於連結部23之截面形狀為圓形，故於轉換方向時， 即使因翼部22之傾斜等，連結部23之彎曲方向有偏差’彎 曲應力仍均等。特別是構成連結部23之線狀構件3〇自身為 將細纖維之絲線紡絲之絲線時，由於彎曲應力分散至各纖 維’故極小。 在此實施例中，使連結部23之長度配合直線路徑之滚 10 201030251 珠保持部1G之翼部22間之直線距離在可於滚珠2與滚珠保 持部U)之保持凹部l〇a間形成微小之間隙的程度亦可依情 況，使連結部23之長度長於直線路徑之滚珠保持部ι〇之翼 部22間的直線距離，而可使方向轉換路捏之彎度更大。 第4圖顯不上述第1實施例之變形例。 此變形例係將滾珠__每隔·輯配置，而為可 以滾珠保持部10從前後各失持2個滾珠2之結構者。 ❹ 如此即使為將滾珠2每2個失持之結構，由於在直線上 時，如第4(B)圖所*，相鄰之滾珠保持部聞之間隔^小 於接觸狀態之2個滾珠之間隔W2，故滾珠2不致脫落。由於 , 此滾珠2為3個時，滾珠脫落，故宜隔2個即可。 藉將滚珠2每2個保持，如第4(c)圖所示，滾珠保持部 1〇間之連結部23之長度增長，正因如此，方向轉換路56之 連結部23之彎度增大，故可使彎曲應力更小。 於組裝於滚珠循環路徑53時’以滾珠2決定滾珠保持部 • 10之位置，而可全周引導，故滾珠保持部10或線狀構件30 在不接觸負載滾珠通路54、無負載滾珠通路55及方向轉換 路徑56之通路壁下移動。 此外，亦可依情況，在1個轉動體保持器中，為將滾珠 保持部10每隔2個滾珠配置之部份與每隔丨個滾珠配置之部 份混合存在之結構。 第2實施例 接著’就本發明之第2實施例作說明。 第3圖顯示本發明第2實施例之轉動體保持器。 11 201030251 轉動體保持器lG〇係保持滾輪1()2之滚輪保持器式。 、卩包含有將簡定間隔㈣之複數滚輪1G2保持成〜 連串將各雜滾輪之排财向後失持之 態保持之錄簡部11G、從錄_部11()於對滾輪 方向垂直相交之方向突出之翼部122、將翼部122間連結之 可撓性連結部123 ’而可以連結部123之變形，在以滚輪保 持4110保持之狀態下，將滾珠2之排列方㈣曲。、 滾輪102以在爽躲滾輪㈣部1H)之«Τ，滚輪1〇2 之旋轉軸相互平行之狀態旋#自如地保#。關於此第2實施 例’如第3圖所示，假設相互垂直相交之χ轴、γ軸、z輛之 垂直相交座標，令滾輪102之排列方向為χ轴方向，令滾輪 102之旋轉軸方向為γ轴方向，令與χ軸及γ軸垂直相交之方 向為Ζ轴方向。 滾輪保持部110為小於滾輪徑之長方體形狀之塊體，於 其排列方向前後兩面設有用以將滾輪102保持成滑動自如 之保持凹部110a。此保持凹部li〇a成形成供滚輪1〇2之圓弧 部進入之圓弧面形狀。當然，滚輪保持部11〇之形狀不限於 長方體形狀。 翼部122之X轴方向（滾輪排列方向）之寬度在圖所示之 例中設定成與滾珠保持部10之X軸方向之寬度相同的寬 度，如第3(F)圖所示，翼部122之X軸方向之寬度A1，宜設定 成滚珠保持部10之X轴方向之寬度A0'以下。 另一方面，翼部122為薄板形狀，如第i(f)圖所示，2 轴方向（與滚輪排列方向及滚輪之旋轉軸方向垂直相交之 12 201030251 方向）的厚度ΒΓ小於滾輪保持部11〇之2軸方向之厚度B〇,。 - 又，連結部123之2軸方向之厚度小於翼部122之Ζ軸方向之 厚度。 又，在第2實施例中，翼部122之2轴方向之位置與滾輪 102之中心大致一致。當然，亦可與第丨實施例同樣地錯開。 連結部123以為樹脂材，且為延伸材之線狀構件13〇構 成’與滾輪保持部110及翼部122成形成一體。線狀構件13〇 〇 4著滾輪1G2之排列方向X，涵蓋轉動體保持器1G1之全長延 伸。此線狀構件130之途中之部份以貫穿各翼部122之狀態 固定成一體，於翼部122間露出部份之部份構成連結部123。 上述滾輪保持部110及翼部122以射出成形成型，線狀 冑件13G與滾魏持部i 1G及翼部122-同以插人成形成形 成一體。 關於此滾輪保持部11〇及翼部122與線狀構件13〇之材 料與第1實施例相同。 _ χ Μ於直線運動引導裝1：之滾輪循環路徑之結構與 圖所示之滾珠循環路徑相同，轉動體保持器雖反覆承受 彎曲但在連結部123大幅撓曲，翼部122不致變形。 ,特別疋為滾輪102時，由於滾輪102以位於移動方向前 後之滾輪保持部110平行地保持滾輪102之旋轉軸間，故可 防止歪斜之產生。 關於此第2實施例之轉動體保持器，與第4圖所示之第i 實知例之變形同樣地’可為滾輪保持部210每隔著2個滚輪配 置以滾輪保持部210將滾輪1〇2每2個從前後夾持之結構。 13 201030251 又，記載於上述各實施例之構成零件之材質、形狀、 其相對配置等只要無特別特定之記裁，便非將此發明之範 圍僅限定於該等之旨趣者。 【圖式簡單~說^明】 第【圖係顯示本發明第丨實施例 1⑷圖係卸除滾珠之狀態之部份立_，第= 滚珠之狀態之部份立體圖，第1(c)圖係部份截斷主要部份 平面圖，第_圖係部份截斷主要部份正面圖，⑹Further, since the thickness t of the connecting portion 23 in the Z-axis direction is also smaller than the thickness of the wing portion 22 in the Z-axis direction, the bending rigidity itself is small, and the bending stress can be reduced. Further, since the cross-sectional shape of the connecting portion 23 is circular, even in the direction of the transition, the bending direction of the connecting portion 23 varies depending on the inclination of the wing portion 22, etc. The bending stress is uniform. In particular, when the linear member 3 itself constituting the connecting portion 23 is a thread for spun filaments of fine fibers, the bending stress is dispersed to the respective fibers, so that it is extremely small. In this embodiment, the length of the connecting portion 23 is matched with the straight path roller 10 201030251. The linear distance between the wing portions 22 of the bead holding portion 1G is formed between the retaining recesses la of the balls 2 and the ball holding portion U). The degree of the minute gap may be such that the length of the connecting portion 23 is longer than the linear distance between the wing portions 22 of the ball holding portion ι of the straight path, and the degree of curvature of the direction changing path can be made larger. Fig. 4 shows a modification of the first embodiment described above. In this modification, the balls are arranged every other time, and the ball holding portion 10 can be configured to lose two balls 2 from the front and the rear.如此 So even if the structure of the ball 2 is lost every two times, because it is on a straight line, as shown in Fig. 4(B), the interval between the adjacent ball holding portions is smaller than the interval between the two balls in the contact state. W2, so the ball 2 will not fall off. Since the balls are detached when the number of the balls 2 is three, it is preferable to separate them. By holding the balls 2 every two, as shown in Fig. 4(c), the length of the connecting portion 23 between the ball holding portions 1 is increased, and as a result, the curvature of the connecting portion 23 of the direction changing path 56 is increased. Therefore, the bending stress can be made smaller. When the ball circulation path 53 is assembled, the position of the ball holding portion 10 is determined by the balls 2, and the entire circumference can be guided. Therefore, the ball holding portion 10 or the linear member 30 does not contact the loaded ball path 54 and the unloaded ball path 55. And the path of the path of the direction changing path 56 moves downward. Further, in a single rotor holder, a portion in which the ball holding portion 10 is disposed every two balls and a portion in which each of the balls is disposed may be mixed. (Second embodiment) Next, a second embodiment of the present invention will be described. Fig. 3 shows a rotor holder according to a second embodiment of the present invention. 11 201030251 Rotary body holder lG tethered to maintain the roller retainer type of roller 1 () 2.卩 卩 复 复 复 复 复 复 复 滚轮 滚轮 滚轮 滚轮 滚轮 滚轮 滚轮 滚轮 滚轮 滚轮 滚轮 滚轮 滚轮 滚轮 滚轮 滚轮 滚轮 滚轮 滚轮 滚轮 11 11 11 11 11 11 11 11 11 11 11 11 11 11 11 11 11 11 11 11 11 11 11 11 11 11 11 The wing portion 122 that protrudes in the direction and the flexible connecting portion 123' that connects the wing portions 122 can be deformed by the connecting portion 123, and the arrangement of the balls 2 (four) is bent while being held by the roller holding 4110. The roller 102 is rotated in a state in which the rotation axes of the rollers 1 and 2 are parallel to each other in the state of the roller (four) portion 1H). Regarding this second embodiment, as shown in FIG. 3, assuming that the vertical intersecting coordinates of the x-axis, the γ-axis, and the z-thro that intersect each other perpendicularly, the arrangement direction of the roller 102 is the x-axis direction, and the direction of the rotation of the roller 102 is made. In the γ-axis direction, the direction perpendicular to the χ-axis and the γ-axis is the Ζ-axis direction. The roller holding portion 110 is a block having a rectangular parallelepiped shape smaller than the roller diameter, and the holding concave portion 110a for holding the roller 102 slidably is provided on both front and rear surfaces in the arrangement direction. This holding recess li〇a is formed into a circular arc shape into which the circular arc portion of the roller 1〇2 enters. Of course, the shape of the roller holding portion 11 is not limited to the rectangular parallelepiped shape. The width of the wing portion 122 in the X-axis direction (the direction in which the roller is arranged) is set to be the same width as the width of the ball holding portion 10 in the X-axis direction in the example shown in the figure, as shown in Fig. 3(F), the wing portion The width A1 of the X-axis direction of 122 is preferably set to be equal to or smaller than the width A0' of the ball holding portion 10 in the X-axis direction. On the other hand, the wing portion 122 has a thin plate shape, and as shown in the i-th (f) diagram, the thickness ΒΓ in the 2-axis direction (the direction of the 12 201030251 perpendicularly intersecting the direction in which the roller is arranged and the direction of the rotation axis of the roller) is smaller than the roller holding portion 11 The thickness of the 2-axis direction of the crucible is B〇. Further, the thickness of the connecting portion 123 in the two-axis direction is smaller than the thickness of the wing portion 122 in the z-axis direction. Further, in the second embodiment, the position of the wing portion 122 in the two-axis direction substantially coincides with the center of the roller 102. Of course, it can be shifted in the same manner as in the third embodiment. The connecting portion 123 is a resin material, and the linear member 13A of the extending material is formed integrally with the roller holding portion 110 and the wing portion 122. The linear member 13 〇 〇 4 is arranged in the direction X of the roller 1G2 to cover the full length extension of the rotor holder 1G1. A part of the middle of the linear member 130 is integrally fixed to penetrate the respective wing portions 122, and a portion where the portion is exposed between the wing portions 122 constitutes a joint portion 123. The roller holding portion 110 and the wing portion 122 are injection-molded, and the linear element 13G is integrally formed by insert molding with the rolling contact portion i 1G and the wing portion 122-. The material of the roller holding portion 11A and the wing portion 122 and the linear member 13A is the same as that of the first embodiment. _ χ 直线 The structure of the roller circulation path of the linear motion guide 1 is the same as the ball circulation path shown in the figure, and the rotor holder repeatedly undergoes bending but is largely deflected at the joint portion 123, and the wing portion 122 is not deformed. In particular, when the roller 102 is used as the roller 102, since the roller 102 holds the roller holding portion 110 in the moving direction in front and rear to maintain the rotation axis between the rollers 102 in parallel, the occurrence of skew can be prevented. The rotor holder of the second embodiment is similar to the modification of the i-th embodiment shown in FIG. 4, and the roller holding portion 210 can be disposed with the roller holding portion 210 for the roller 1 every two rollers. 〇2 Every 2 structures that are clamped from front to back. 13 201030251 Further, the materials, shapes, relative arrangements, and the like of the components described in the above embodiments are not intended to limit the scope of the invention to those skilled in the art unless otherwise specified.
