New description: [New technical field] The present invention relates to a linear transmission device, in particular to a linear ball guiding device which can reduce the running noise and avoid excessive wear of the balls. [Prior Art] As shown in "1A", "1B" and "2", the ball shaft of the prior art is widely used in general linear actuators. The ball screw package contains a set of simple shafts, a shaft 2 〇 and a plurality of balls 30 running between the sleeve and the shaft 2 . The sleeve 1 is slidably sleeved on the shaft 2〇, and the sleeve 10 is linearly movable relative to the shaft 2〇, and the sleeve 10 and the shaft 2 are lowered by rolling the ball 1%. Relatively moving friction. The shaft 2 has an inner rolling groove 22' and the sleeve 10 has a rolling groove ill corresponding to the inner rolling groove 22. The inner rolling groove 22 and the second rolling groove 11 are used for the ball 3 to run on the sleeve. Between the barrel 1 and the shaft 20. The sleeve 1 includes a main body portion n, two inner side ports, and two outer side portions 13. The main body portion 11 is provided with a ball passage for the ball 30 to be turned therein. The inner portion 12 is provided with an inlet 121 and an outlet 122, and the outer portion 13 is provided with a bend 131, wherein the inlet 121 of the inner portion 12 communicates with the curve 131 of the rolling groove 111 and the outer portion 13 outside the main body portion, so that the ball 30 The outer rolling groove U1 can be operated into the tunnel 131, and the outlet 122 of the inner portion 12 communicates with the ball passage 112 of the main body portion n and the curved portion 131 of the outer portion 3 so that the ball 3 can be operated from the curve to the ball passage. 112 towels. Thus, the balls 30 can be steered by the inner side portion U and the outer side portion ls at both ends of the main body portion 11, and continuously circulated in the ball shaft. The ball shaft of the prior art allows the ball 3 to be circulated, but the M319341 ring device is assembled from the inner portion 12 and the outer portion 13, wherein the outlet portion 122 and the inlet 121 of the inner portion 12 are The joint of the curve 131 of the outer portion 13 is easy to form a drop, so that the gap between the ball 30 and the sleeve 10 is too large, which affects the smoothness of the operation of the ball shaft, and causes a sharp noise when the ball shaft is running, and the ball 3 is caused by the joint. 〇 Excessive wear and tear. In addition, the ball shaft of the prior art does not take into account the ball 3 〇 - the contact with the sleeve 10 and the turn 20 is reduced, so that the ball shaft is easily oscillated when subjected to a force, thereby affecting the smooth running of the ball shaft. [New content] The circulation device of the previous technical ball bearing shaft is easy to make the ball run unsatisfactory, and because the ship soft is not considered, the new type of linear ball guiding device is provided. The sleeve can be relatively sturdy and has a rolling resistance between the plurality of sleeves and the shaft. The shaft is further moved to reduce the movement of the sleeve surface on the shaft to form at least the at least the first-first rolling groove, and the sleeve has a groove and at least the inner circumferential surface of the sleeve and corresponds to the first rolling groove The second rolling is performed on the first moving groove and the first shooting ball rolling guide device is characterized in that: The new linear roller looper has at least Ί _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ Zhu Weidi enters and exits the second rolling ditch, and the M319341 lifts the surface of the ball. In addition, the sleeve is passed through the center of the second roller lining to contact the contact point of the first rolling groove to form a & angle, and the radial line of the shaft passing through the center of the rolling groove is in contact with the ball. The groove forms an angle of 45 degrees. The function of the knife is that the linear ball guide has the smoothness of the integrated ball circulation ball running to reduce the running rate of the device and the wear rate of the ball. And when there is a force between the ball and the guiding device, the swing occurs when the force is applied. There are flaws in contact, which can be effectively avoided = in the implementation of the towel detailed description of the details of the new thief and the advantages, straight 1 valley 32 He familiar with the relevant art know the skill of the new model and according to Jing: tr (four) number _卞 细 , , , , , 任何 任何 任何 任何 任何 任何 任何 任何 任何 任何 任何 任何 任何 任何 任何 任何 任何 任何 任何 任何 任何 任何 任何 任何 任何 任何 任何 任何 任何 任何 任何 任何 任何 任何 任何 = = = = = = = = = = The scope of the special _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ ®"Qing, the new type of system through the 3^-bead guide device, such as the ball 30 as the connection 2 =, and hunting by the cycle running on the sleeve 10 and the shaft as a contact medium, reduce the sleeve 10 The M319341 grinding 2 between the shafts 20 allows the sleeve 1 to smoothly slide relative to the shaft 2〇. The groove is a cylindrical rod body having two first circumferential surfaces symmetrical with each other. Two rolling grooves 21 are formed along the axial direction of the shaft 20 outside the shaft 2〇: the inner moon #20 is opened inside. A concave groove with a circular arc shape. Each of the first rolling elements, = Keqingcheng-oil groove 211 (as shown in Fig. 8), is used to accommodate a $ to reduce the frictional resistance of the balls 30 and the surface of the first rolling groove 21. The mountain stalk 1G material - the inner towel empty refractory body, has - the perforations along the two ends of the shaft ' (four) for the rotation to slidably load the towel. The sleeve 10 has a two-rolling groove 1G1 and a two-in-one relative to each other. Each of the first moving grooves 101 is formed on the inner circumferential surface of the sleeve 10 in the axial direction, and is formed into a circular arc-shaped concave groove toward the sleeve 1〇', and its size is slightly larger than the ball 30, so that the ball 30 can be: The two rolling grooves 101 are smoothly rotated. Each of the first rolling grooves corresponds to each of the first rolling grooves 21 of the shaft 20, and the bottom of each of the second rolling grooves ι〇ι forms an oil groove 102 (as shown in FIG. 8). In order to accommodate a lubricating fluid, the frictional resistance of the ball 30 and the surface of the first rolling groove 1〇1 can be reduced. In addition, the width of the notch of the second rolling groove 101 is smaller than the straightness of the ball 30, so that the ball 3〇 can be kept rolling in the first rolling groove 101 without being detached from the second rolling groove 1〇11. The linear rolling grooves 51 of the sleeve 10 are circular perforations extending through the end faces of the sleeve 1 in the axial direction, and are slightly larger in size than the balls 30, so that the balls 3〇 can be smoothly rotated in the linear rolling grooves 51. Each of the linear rolling grooves 51 respectively corresponds to the second rolling grooves 101 in parallel, and is corresponding to the second rolling groove 1〇1 in the linear rolling groove 51 in the space to be divided into two oil grooves 511 for accommodating A lubricating fluid reduces the frictional resistance of the balls 30 and the surface of the linear rolling groove 51. M319341 Please continue to refer to "Fig. 4", "6A", "6B" and "6C". Each ball circulator is a short hollow cylinder with a central hollow. Firmware 15 (shown in Figure 5) is attached to both sides of the sleeve 1 and has a catching groove 52, respectively. Each of the return grooves 52 is a U-shaped ball turning passage which is slightly larger in size than the balls 30, so that the balls 30 can be smoothly rotated in the return grooves 52. The width of the notch of each of the return grooves 52 is also smaller than the diameter of the balls 3〇, so that the balls 30 can be kept rolling in the return grooves 52 without being separated from the return grooves, and the rolling grooves 52 are not smooth. The second rolling groove 1〇1 with the sleeve 10 is not coplanar in the space. The inlets 521 of the respective return grooves 52 are respectively connected to the ends of the second rolling grooves 1〇1 of the sleeve ι, so that the balls 3〇 can enter and exit the second swash grooves 101 and the return grooves 52 through the inlets 521, and the respective reflows The outlet 522 of the groove 52 is respectively connected to both ends of each of the linear rolling grooves 51 of the ferrule 10, so that the ball 30 can be taken in and out of the straight line rolling groove 51 and the return groove 52 by the outlet 522. Thus, the ball 3 turns by the return groove 52 of the ball circulator 14 and travels back and forth between the linear rolling groove of the sleeve 1G and the first and second rolling grooves 1〇1. The return groove 51 of the two ball circulators 14 is connected with the linear rolling groove 51 of the sleeve 10 to form a return flow passage, and the ball 30 is reflowed from one end of the second rolling groove 101 to the second rolling groove (1). At the other end, in this way, it is continuously cycled. wContinued to refer to "7th Phoenix" and "8th Diagram", the first flooding groove 21 of the shaft 2〇 and the second rolling groove 1 of the corresponding sleeve 10 (n-paired to form a slightly spherical ball) The rolling groove of 30, which is lubricated by the lubricating oil in the vinegar 1 〇 2 and the oil groove 221, allows the ball 30 to be loaded therein and smoothly performs the rolling operation. Further, the sleeve 10 passes through the center of the third swaying groove 101 The diameter line is in contact with the material % second rolling 9 M319341
