Description of the Invention: [Technical Field] The present invention is applied to a rolling element holding chain design in a linear motion mechanism, and an axially extending elastic rolling element holding chain axially extends into a plurality of rows of rolling The body is held therein and is separated from each other by a certain distance, and the rolling element retaining chain and the rolling body are circulated in a circulation passage provided by the linear motion mechanism. [Prior Art] The current linear transport mechanism has a lion piece and a track piece that can be extended smoothly; the moving parts and the financial parts are relatively small and healthy - the mutual correspondence with the moral road, the track, the - column rolling body and the track contact Rolling on the track; moving parts and providing a return channel and two turning tracks for each column corresponding to each other, the turning track connecting the return channel and the end face of the track to produce a σ, forming a circulation channel, and the rolling body can be tracked The revolving channel enters the return channel, and the return channel, and then the trajectory enters the track zone, so that the rolling elements can circulate in the path of the roadway; by rolling the rolling bodies, the moving parts can follow the track on the track member. Run infinitely. In order to avoid the collision between the two rolling elements, the moving parts provide a rolling element holding chain, and the majority of the holding blocks are located between the rolling elements and are connected by a connecting strip. The holding block located in the rolling body will The rolling bodies are separated by two or two to avoid collision between the rolling bodies, and the rolling elements are kept at a certain distance to run the ring, so that the moving parts can be operated in an open position. In general, the rolling element holding key disclosed in Japanese Patent JP 05-052217 (japanese ined Patent publication) is directly formed by the tree 1334909 fat injection molding. However, when the linear motion mechanism is getting smaller and smaller, it is less likely to be shot and formed, and it is easy to produce a situation in which it cannot be filled. In addition, since the tensile strength of the resin is small, it is not guaranteed to be broken during the cycle operation, and thus the breakage is often caused. Not running well. In order to overcome the above problems, the design of the rolling element retaining chain disclosed in the US Pat. No. 6,142,671, wherein the retaining block and the connecting strip are made of a bendable metal strip 'because the tensile strength of the metal is much higher than that of the resin, In terms of aspect, it is possible to increase the tensile strength of the rolling element retaining chain, and it is less prone to breakage, and on the other hand, the thickness of the connecting strip can be reduced while still maintaining a higher tensile strength. When the thickness of the metal strip is not less than 0.1 mm, the manufacture of a smaller size can be easily performed by punching and bending. Assuming that the elastic modulus of the metal material is E and the metal φ ′ of thickness h is bent by a circular arc having a bending radius of p, the stress generated is Jr 5 Ε=210, 〇〇〇 N/mm2 > p
例如鋼製金屬帶厚度h=〇. 〇3mm =l〇nmi 則 σκ= 315 N/ mm2，由求 高於樹脂，所以在同一蠻A主依η 7 接條兩端在迴轉道時造成彎曲不完全而迴轉不順暢，並且 在擔％運行時，容易材料疲乏而斷裂。 j服上述之問題如美國專利US7,咖，()47所揭露之滾 保持鏈之設計由—呈触狀之金卿製成，利用雛 以a加可彎曲部份，以分攤所需彎曲之幅度 ’例如圖三 十四，二斗·石一丄 ^ 二十/、所示，其中金屬帶在90。度彎曲 範，=有N個皺摺’彎曲半彳$為^，触深度為τ，為簡 化计算’假設皺摺尖端為尖點，可得墙摺寬度，敵 摺長度L，其幾何關係如下： V = ρ· r 1 —cos ^90° V \For example, the thickness of the steel metal strip h=〇. 〇3mm =l〇nmi then σκ= 315 N/mm2, which is higher than the resin, so the bending is not caused when the same A7 main η 7 strip ends in the turret It is completely smooth and not smooth, and it is easy to break and break when the weight is running. j service the above problems, such as the US patent US7, coffee, () 47, the design of the roll retaining chain is made of - touched Jinqing, using the younger to add a bendable part to share the required bending The amplitude 'such as Figure 34, two buckets, stone one 丄 ^ twenty /, shown, in which the metal belt is at 90.

Therefore, when the thickness of the metal strip is h, the stress generated when the curved arc is bent into r is 1334909 Eh σ =-- 2-r Generally, the diameter of the circulating guide concave rolling body provided by the circulation passage is (U~ 0· 2, and the depth of the fold is smaller than the ^^' of the groove, and the radius of gyration is about 15 ~ 3 times the diameter of the rolling element. 9 ^ For example: the diameter of the rolling element PD = 5_, the modulus of elasticity of the steel sheet metal E =210,000 N/mm2, radius of gyration p=1〇mm, then T=0.8mm, h=0.0685mm, N=20, 2W=0.8mm, aR= 315 N/ mm2 , T=1.0mm, h=0.823mm, _, 2W=0.8mm, a 314 N/ mm2 j T=0. 8_ 'h=0.126mm, _, 2W=0· 4mm, σκ=315Ν/ face 2; therefore, under the same stress, the number of open N The more or the wrinkle depth T is deeper, the more the thickness can be increased; and the size of the metal according to the general design is as follows, the thickness of the gold material with the same stress can reach about two to four times the metal band without the axis, and It can solve the problem of no wrinkle metal strip. However, this design will make the axially extending connecting strip formed by the metal strip to be an enemy fold instead of a smooth surface, since the rolling element retains the axial extension of the chain and the connecting strip will The closed circulation guide groove provided by the circulation passage of the linear motion mechanism operates to guide the rolling element to maintain the direction of the slit smoothly and smoothly in the circulation passage. The circulation passage closed circulation guide groove is always composed of two pieces. The above = component combination, so when each wrinkle end point passes through the joint, it will cause unstable beating, and therefore the operation will not be smooth and smooth. 1334909 SUMMARY OF THE INVENTION It is an object of the present invention to provide a rolling with a flexible metal sheet. The body retaining chain design can solve the above-mentioned problem of using the metal sheet design to produce the stamping of the metal sheet, and avoid the operation caused by the wrinkles, and can even increase the tensile strength of the rolling element connecting strip as the wrinkle design.

Deformation in the revolving path (4), and the ability to reverse (four) can be achieved. Do not produce plasticity faults: the thickness of the sheet is f 9 ρ /ρ, which makes the metal 溥 'where R»·· is the breaking strength of the metal 10 pieces of material Lifetime, or the number of times of repetition. For example, when the metal piece is a defective product, the number of times of repetition is - more than one million times, f = 〇 · 6 ~ 0.7. The circulation passage provides a circulation guide groove extending in the running direction. The closed type is usually formed by combining two parts, and the joint has a discontinuous surface due to misalignment, and the joint strip formed by the metal foil has no wrinkles on both sides. The fold remains as a smooth surface; therefore, there is no obstruction at the joint of the loop guide groove to cause misalignment. In order to combine the horizontal strips between the spacer block and the metal sheet holes, the horizontal strips are provided with protrusions for preventing axial movement along the horizontal strips, and recesses or small holes are formed in the horizontal strips for embedding the spacer blocks. The spacer block is wrapped in a shape corresponding to the surface of the rolling element, and the rolling element is held between the two spacer blocks which are wrapped on the right and left sides in the rolling element holding chain without being freely dropped. The metal piece can be stamped and etched. The material of the spacer block may be a resin, and a resin composed of a mixture of oil, glass fiber, carbon fiber, and the like. The combination of the metal sheet and the resin spacer block can be injection molded to project the spacer block out of the metal sheet. Another combination method is that the metal piece is divided into two, and the spacer block is divided into two left and right half blocks. The left and right two spacers have opposite positioning pins and holes and the grooves for accommodating the metal strips. A complete spacer is formed after being bonded to the left and right sides of the metal strip. Another combination method is that the vertical plane of the metal piece is divided into two. The spacer block is divided into two front and a half blocks. The front and rear two spacers have opposite positioning pins and holes and the grooves for accommodating the metal strips. A complete spacer is formed on the front and rear sides of the horizontal strip of the metal sheet. The locating pins of the two spaced half blocks can protrude from the two spaced half blocks, and the covering surface of the rolling body is formed on the end face of the positioning lock, so that the rolling elements are covered and spaced by the end faces of the positioning pins, so the space between the positioning locks is therefore It can be used to extend the lubrication effect. When the metal sheet is reduced in thickness due to the required bending ability, and the rolling element retains the key to the thief, the metal sheet on the two Us can be overlapped and the tree sill spacer can be bonded thereto, thereby increasing the rolling. The body maintains the tensile strength of the bond, and the thickness of each piece of metal sheet hl, b, <h0, since each metal piece can be single-curved, so that the rolling element composed of a plurality of pieces of metal piece can maintain the chain health The single-gold composition of the rolling elements maintains the bending ability of the keys 'but its tensile strength will increase by a multiple with the number of overlapping sheets. When the left and right or front and rear spacers are used, the grooves of the left and right or the front and rear spacers can be slightly larger than the metal strips, and the space for each piece of metal to be moved more when bending is provided. To reduce the resistance between when the overlapping metal sheets are bent. In order to increase the strength of the rolling element holding chain spacer block, at least the horizontal strips axially arranged between the holes and connected to the metal 4 connecting strip are divided into upper and lower halves, and the upper and lower ends of the spacer block and the upper and lower halves are horizontally stripped. The endpoints are joined together to form a rolling body retention chain. In order to reduce the frictional resistance of the metal sheet during operation in the circulation guiding groove, at least one piece of metal sheet may be resin-coated and injection molded together with the spacer block. The rolling elements can be balls or rollers. = The thickness of the metal sheet is much smaller than that of the rolling element holding chain made of resin, so there is space in the design to overlap the metal sheet'. In the metal sheet rolling body of the present invention, 1334909, the metal sheets at both ends of the chain design overlap each other. And providing at least one spacer half at both ends, at least one spacer half at one end and at least one spacer half at the other end corresponding to each other, and corresponding positioning pins and positioning holes are combined and fixed to form a complete interval The block, as well as the closed rolling element retaining chain, the metal piece rolling element retaining chain design thus solves the problem that the two ends are open and cause unsatisfactory operation. Another design of the rolling element retaining chain design of the metal sheet of the present invention is to combine at least one metal piece and the spacer half piece into a semi-metal piece rolling body holding key, and the spacing half has corresponding positioning pins and positioning holes, at least one The metal piece and the spacer half piece can be combined in the injection molding manner, and the two semi-metal piece rolling elements keep the chain combined into a complete rolling body holding chain through the combination of the corresponding positioning pin and the positioning hole, and the semi-metal piece rolling body retaining chain design will The difficulty of directly releasing the mold during the injection molding of the coated spacer block can be simplified and solved. [Embodiment] As shown in FIG. 1 and FIG. 2, a rolling element holding chain 1 is composed of a metal piece 02 and a spacer block 3, wherein a metal piece 2 has axially arranged holes 21 as shown in FIG. A horizontal strip is formed between the holes 21 and two holes are formed. The spacer block 3 is coupled thereto. A connecting strip 23 is formed on the upper and lower sides of the hole. All the horizontal strips are connected thereto; a rolling element array 5 is It is held in the hole 21 and is separated by a spacer block (four); as shown in FIG. 3, the spacer block 03 is covered with a surface corresponding to the rolling element 05, and the rolling elements are held between the two spacer blocks which are wrapped on the left and right sides. The rolling elements hold the chain 1 without falling freely. As shown in FIG. 5, the rolling element holding chain 1 and the rolling body row 〇5 are located in the loop of the Weidao 61 provided by the moving member 06; the circulation channel 13 S ^ 1334909
