Description

1240045 V. Description of the invention (1) [Technical field to which the invention belongs] The present invention relates to a rolling element guide module, which is a rolling element holding device applied to a linear drive element; generally speaking, the linear drive element system is applied On machine tools, electronics, automation equipment, semiconductor equipment, etc. [Prior art] In the linear transmission elements of the prior art, the rolling element retainers can be roughly divided into two types: the first design retainer is a separate entity, and the other retainer is a design that connects many separate entities. Firstly, as shown in FIG. 10, the sliding block 60 is fitted on a stick (not labeled) and moves. A sliding element 70 is provided in the sliding block 60, and a single holding is sequentially placed between the rolling elements 70. Device 50 so that the rolling elements 70 do not collide with each other. When assembling a linear transmission element using this design, it is necessary to sequentially place each rolling element and a single retainer into the sliding block in sequence, which is quite time-consuming and labor-consuming; furthermore, the single retainer and the rolling element need to be properly Contact, if the distance between the retainer and the rolling elements is too large, the retainer is easily detached from the two rolling elements, and the retainer may touch the return wall during return steering, which may cause the return steering to be smooth. In severe cases, it may even cause the return channel to become stuck. However, if the contact is too close, there will be significant frictional resistance between the retainer and the rolling element, and naturally, the return and steering will not be smooth. As shown in FIG. 11, for the design of a retainer that connects many individual entities, the link retainer 5 1 in the figure connects the spacer 5 1 1 with a flexible link chain 5 1 2 to enable each rolling element 7 0 rolls in the space between two spacer blocks 5 1 1

1240045 V. Description of Invention (2). The manufacturing method of this connection holder 51 must first place the rolling elements in a mold and make it by overmolding plastic injection. The material properties and injection machine performance of this method must have high requirements, which relatively increases the manufacturing cost; And because of its more special manufacturing method, the rolling element is in close contact with the spacer block of the connection holder, so that the rolling resistance of the rolling element is too large; and the spacer block of this connection holder and the connection chain are fixed at a fixed angle, so The degree of steering freedom during reflow is subject to excessive restrictions, resulting in unsmooth turning and affecting the smoothness of movement. Based on the above, the retainer of the linear drive element of the prior art is in urgent need of improved refinement. [Objective of the Invention] The purpose of the present invention is to provide a rolling element guide module, which has a better steering function, so that the rolling element guide module can run smoothly in the return path, and allow rolling The components can complete the cycle smoothly. [Summary of the Invention] At present, linear drive elements are widely used in general industrial machinery and precision machinery, and rolling element retaining devices are applied to linear drive elements, and they have been paid more attention, especially in connection design. The rolling element guide module of the present invention is a connection design holding device. The holding device is transformed from an integrally formed structure into a modular structure of a combination of parts. When the rolling element guide module changes the direction of movement,

This combination is designed as a screw-fit structure, which allows the rolling elements to lead to the rolling elements. In addition, the structure can be a cylindrical structure that can be designed to be round and free to rotate and be transported on the return flow path. In addition, the wear-resistant flexible material has a longer life. For the sake of convenience, I have read the following formulas for illustration and rotation, and more clear scrolling. The invention is further improved, and the pairing is greatly improved, which can greatly improve the module's ability to smoothly invent the rolling structure and triangular arc-shaped grooves. The performance is not produced during the invention, and the rolling is made smooth. The component guide module is a module combination of parts. The general injection method can be used to manufacture the difficulty, so that the manufacturing cost can be quite a step, and the structure can be completed smoothly and smoothly. As a result, the rolling element twisting element guide element and the rolling element guide element are guided on the guide die or the polygon and the groove element. Leader module leader module guide structure and slot leader module rolling tuple part-shaped column structure structure of the lead module of the module, the structure of the module between the components of the module is turned and connected to each other. The combination of the column structure, etc., and the groove joint has a high degree of free steering, the material can be selected for better performance and further understanding of the characteristics and technical content of the present invention, please refer to the embodiment of the present invention in detail, but this embodiment and The drawings are for reference and are not intended to limit the invention in any way.
