Description of the Invention: [Technical Field] The present invention relates to a linear transmission element, and more particularly to a transmission element in which two adjacent rolling elements are separated by a spacer to avoid collision between two adjacent rolling elements. (eg rolling element screw, roller screw or linear slip). [Prior Art] Due to the increasing use of linear transmission components in modern industries, various linear transmission components have been widely used in human life, processing plants and high-tech equipment, such as linear slides and rolling elements. Screws, roller screws, etc.; in particular, large-scale precision machines are equipped with different rolling element screws or linear slide systems. Although the development of linear transmission components technology is very rapid, consumer users still need technology. Constantly improving, so there are still many problems that still need to be developed, especially in the field of many high-precision manufacturing industrial machines that need more stable and quiet, and there are more and more sounds and developments. Therefore, some technical blind spots of linear transmission components are extremely urgent. Add research and development improvements. In the rolling lane (3) of a linear transmission element (for example, a rolling element screw, a roller screw or a linear sliding) which generally has a spacer, the arrangement of the rolling elements (1) and the spacer (2) is as follows. As shown in Fig. 1A and Fig. 1B, a spacer (2) is provided between each rolling element (1) as a component for eliminating collision friction and noise in 201219678. Most of the spacer (1) products are required to be miniaturized and single. Material, integral, single size, but it is not practical for the following reasons: Since the linear transmission element is placed in a large number of rolling elements (1), the clearance reserved between the rolling elements (1) must be minimized. Because of this, it is possible to prevent the spacer (2) from forming a space sufficient for the spacer (2) to traverse when the rolling element (1) reserves a space, thereby causing the spacer (2) to be dumped, and the spacer (1) and The rolling track (3) creates interference, so the prevention method is to reduce the rolling element (the gap after the concentration is minimized) to make the rolling body (1) roll more smoothly (the rolling body will not be stuck in the system, however, the rolling body should be made (1) The gap after the order is reduced to a minimum. The pre-common practice uses the spacers of different thicknesses to adjust 'but the spacers of different thicknesses need different storage positions for the official management, so the storage management cost will be increased; and the assembly personnel must also distinguish the _ sub- The size can be assembled and the assembly time can be extended; and the spacers of different sizes must be manufactured with different tools, and the accuracy of the mold will be deviated after the mold is used for a long time, so that the size of each spacer is originally set. Different sizes and different sizes of spacers are quite inconvenient in manufacturing, storage management and assembly. Relatively increase the cost. Therefore, the need to solve the above problems is becoming more and more urgent as the development and application of linear transmission components become more and more popular. Rolling 201219678 moving screw is not the most important selling point for manufacturers when competing. Therefore, how to develop linear transmission components that meet the needs of users has become the focus of research and development in the industry. The problem of the prior art, the inventor has improved through research, and finally The invention for achieving the object of the invention is born. That is, the primary object of the invention is to develop an adjustable spacer to minimize the gap between the rolling elements and the spacer. For the above purposes, the invention is a The transmission component of the spacer comprises: a long shaft which is in the form of a long strip, the outer edge of which is provided with a rolling groove; a moving module which is arranged on the long axis and which can reciprocate relative to the long axis The moving module is provided with a rolling groove relative to the rolling groove, the rolling groove and the rolling groove form a load path, and the moving die is further provided with a return channel, and the return channel is connected to the load path, and Forming a cyclic path; a plurality of rolling elements, which are accommodated in the circulation path; a plurality of spacers disposed between the rolling bodies for spacing the two rolling elements, the spacer having a body, the system having Two end faces, the two end faces are provided with a plurality of columnar bodies protruding toward the rolling elements, each of the columnar bodies has a gap between each other, and each of the columnar bodies 201219678 has a retaining end face, each of which is maintained Based surface constituting a rolling member of the holding surface, and each of the cylindrical elastic system can withstand squeezing the rolling bodies and deformation. Wherein, the outline of the body is circular or rectangular. Wherein, the rolling system is a ball. Wherein, the rolling system is a roller, and the roller has an axis. Wherein, the axes of the rollers on both sides of the spacer are arranged in a staggered arrangement. Wherein, the axes of the rollers on both sides of the spacer are arranged in parallel. The contour of the retaining surface is arranged relative to the surface rim of the rolling body. In order to further understand the features and technical aspects of the present invention, reference should be made to the description of the embodiments of the present invention and the accompanying drawings. . [Embodiment] Please refer to FIG. 2 to FIG. 8 , which is a first embodiment of the present invention. The present invention is a transmission component with a spacer, comprising: a long axis (1), which is a long strip. a configuration having a rolling groove (11) on the outer edge thereof; a moving module (2) disposed on the long axis (1) and reciprocally movable relative to the long axis (1) of 201219678, the movement The module (2) comprises a moving body (2A) and a reflow element (2B), and the moving body (2A) is provided with a rolling groove (21A) opposite to the rolling groove (11), the rolling groove (11) And the rolling groove (21Α) ^ί^ constitutes a negative channel, and the reflow element (2Β) is provided with a return channel which is connected with the load path to form a circulation path; 3), it is accommodated in the circulation path, the rolling system of this embodiment is a spherical ball; a plurality of spacers (4) are disposed between the rolling bodies (3) for separating the two rolling Body (3), the spacer has a body (41) whose outer shape is circular (the outer contour of the body is circular and is optimally configured because of the circulation of the balls) The section of the diameter is generally circular, so that the circular comparison does not interfere with the circulation path, and if the contour is other shapes, the body (41) has both end faces (411), and the end faces ( 411) is provided with a plurality of columnar bodies (42) protruding toward the rolling body (3), each of the columnar bodies (42) having a gap (43) between each other, the gap (43) providing lubrication The oil (5) is accommodated therein, and the rolling element (3) can also be wetted when it is in contact with the columnar body (42), and each of the columnar bodies (42) has a holding end surface (421)' The retaining end surface (421) is configured to hold a retaining surface (44) of the rolling element (3). The contour of the retaining surface (44) is disposed relative to the surface contour of the rolling body; and each of the cylindrical bodies (42) is It has a deformation of the 201219678 performance bearing rolling element (3). When the transmission component is assembled, by the effect of deformation of the columnar body (42), the gap generated between the rolling element (3) and the spacer (4) is absorbed, so that the rolling elements accommodated in the circulation path are obtained. (3) The gap between the spacer (4) is reduced to less than __ half of the diameter of the rolling element (3) or there is no gap, so the design of the columnar body (42) of the spacer (4) of the present invention is only required A single size can improve the conventional problem, so that the spacer (4) can be made by only one mold, the relative manufacturing cost is also greatly reduced, and the transmission component is also more convenient and quick. In addition, this embodiment is described by a ball screw, but the spacer can also be used for the linear sliding path, because the rolling elements and spacers of the linear sliding rail are arranged and assembled the same as the ball screw. Therefore, I will not repeat them here. Referring to FIG. 9 to FIG. 12, the second embodiment of the present invention is different from the first embodiment in that the rolling element (3) is a roller, and the roller appearance is a cylinder having an axial center (31); the outer contour of the body (41) of the spacer (4) is of the optimum configuration of the crucible, since the rolling element (3) is a roller and the cross section of the circulation path The system is generally rectangular or rhombic, so the rectangle is set to not interfere with the loop path. If the contour is other shapes, the rolling element (3) is located on both sides of the spacer (4). 3) The axes are arranged in a staggered arrangement (as shown in Figure 10) or in parallel (as shown in Figure 12). 201219678 The above mentioned, so the "industrial availability" of the present invention should be unquestionable. In addition, the characteristic techniques revealed in the examples of this case have not been seen in publications before the application, nor have they been The public use not only has the fact that the effect is improved as described above, but also has an additional effect that cannot be neglected. Therefore, the "novelty" and "progressiveness" of the present invention have met the patent regulations, and the application for the invention patent is filed according to law. Pray for review and early grant of patents.
