The beehive structure won't produce much friction for constraining rolling element and keeping the rolling function.

Description

1263742, } V. INSTRUCTION DESCRIPTION OF THE INVENTION (1) Technical Field The present invention relates to a rolling element holding module which is a holding device for a rolling element applied to a linear transmission element; Parts are used in machines for machine tools, electronics, automation equipment, and semiconductor equipment. [Prior Art] As shown in FIG. 7, a rolling element chain 4 1 is placed in the space 413, and the connecting chain 412b is used to join the chain 412a to form a flat elongated chain. The bonding chain 4丨2a includes at least one holding member 411, so that each rolling element 丨丨 can be clamped by the holding member 411 while rolling in the space 4丨3. Although the rolling element chain 4 1 is on the Q side: it can be set in the L direction, but the single-holding element 411 cannot position the vertical direction of the rolling = 4 1 , so the rolling elements are easily dropped and assembled. The big problem, secondly when walking on the return path, the rolling element 丨1 can jump off the space in the 4th turn and get stuck in the return path. FIG. 8 is a retainer design connecting a plurality of individual individuals. The connecting brackets in the figure are connected to the spacer block 511 by a flexible connecting chain 512, so that the rolling elements 11 are placed in the space of the two spaced blocks 511. Rolling, if the spacer block 511 and the key 5 1 2 are assembled, a large amount of manpower is required to be assembled, and the rolling element 1^ also needs to be manually assembled, so that the components having a small size are themselves combined with 2 ί and consumes Shou. If the spacer block 5 11 and the connecting chain 5 1 2 are designed to be integrated, the spacer block $ 1 1 belongs to the concave state in the point of the modulo 2 = Π 10, so the loosening of the day-to-day shackles must produce barbs (ie, The mold core and the component cannot be smoothly separated from the fifth page 1263742 by the interference. 5. The invention description (2) type), the forced release has a size limitation and a 曰 shape, so the figure 8 causes the component to change. And there are still shortcomings to overcome. Figure 9 is a rolling element holding chain, wherein the holding chain 61 and the spacers γ are connected by a connecting chain 612 on both sides. Although there is a possibility, the biggest problem is that the round hole 613 on the partition plate 611 is molded. Set = 丄:::Into-Cylinder with a small diameter and a long length, which is injected into i and then becomes S. When the mouth is to be ejected, the cylinder (4) noisy transmission mechanism must first be taken out of the cylinder. However, the finished product is: but the 2 cylinders are tightly coated to make the extraction more difficult, and at the same time, the problem of deformation is removed; secondly: the discharge : After several times of entering and exiting, there will be a large injection pressure in the injection molding. This kind of body is quite easy to be deformed or broken by the strong pressure. Because the shape of the chain 61 is not mass-produced, the mold is complicated. Therefore, the maintenance of the prior art linear transmission components has the need to urgently improve the precision. [Summary of the Invention] The mechanical and ΐϊΐϋ linear transmission component phase #1 should be in the general industrial machine. The component is on the '" and the rolling element holding device is applied to the linear transmission; the transmission component is gradually being heavy. In particular, the joint design maintains the rolling elements of the present invention, and the present invention introduces mold development characteristics and greatly reduces costs. The concept of a module using a general injection molding method makes the invention extremely fast

V. Inventive Description (3) In addition, the present invention adopts a honeycomb structure as a space, and its shape has a strong magnetic=degree, and at the same time, can effectively position the rolling element, and the port positioning function generates a steering function of the rolling element. limit. According to &, the invention: to separate the rolling elements, and to make the holding module roll; the article again uses the concept of assembly, not only assembly: group "suitable length, so more suitable for different needs of the product r In order to facilitate further understanding of the features and technical contents of the present invention, the embodiment of the present invention is the last name, but this embodiment: Figure " The present invention is not limited to the present invention. Embodiment 1 is a cross-sectional view of a spacer-shaped structure of a first embodiment of the present invention, and the rolling element 1 1 is required for the purpose of the injection. The rolling diagram of the forming and subsequent structure is saved from the drawing to the point I. The moving element retains the rolling. However, in the single element diagram, the rolling element 11 is positioned by the honeycomb structure (the six elements are maintained at the contact surface 0 0). Figure 2 shows that the rolling element 11 is in contact with all the rolling elements, so that the rolling element can be effectively reduced by the rolling contact surface contact. Force, the steering function of the rolling. 彳, the production of the honeycomb at the end of the knot is expected to be quickly manufactured with injection molding, molded parts produced, in the mold development and design is not feasible, the rolling elements keep the contact surface will make The product is hooked (that is, the product cannot be successfully ejected in the mold core) 1263742 V. Inventive Description (5) In addition, the material of the present invention may be selected from a wear-resistant flexible material, so that the rolling element holding module of the present invention is turned to The performance is better and the life is longer. In summary, the case is not only innovative in terms of space type, but also can improve the above-mentioned effects compared with the conventional technology, and should fully comply with the statutory invention patent requirements of novelty and progress. To file an application in accordance with the law, I urge you to approve the application for this invention patent, so as to encourage creation and to be sensible.
