Fig. 1 is a schematic view of the screw u and the ball nut 12. A kind of 〗 〖includes - screw u (10) - county 12, the ball screw from the set of money set on the screw „, and the screw u and the ball _ 12 adjacent to the position should have a thread groove (1), 121, the thread groove m, (2) together form a path through the path 'multiple series (10) cycle path (10) moving ^ by the ball B in the cycle _ inner rolling 'can make the screw 11 and the ball 12 to perform the phase rotation motion, and the ball nut 12 along the screw u However, when the screw 11 is provided with the support member 13 for avoiding the sagging of the screw u, if the ball nut 12 is sensed to the branch M3, the support member I3 must first be lowered to raise the ball nut 12 and then raised. Thus, not only does the movement of the ball nut 12 become inconsistent, and when the support member 13 is lowered, the screw n will sag due to its own weight, and the screw 11 will sway due to the load and movement of the ball nut U, causing waves. The bead screw device 1 has a problem of process accuracy when applied. Ο Ο 200938751 Rolling:=:r-一-[Summary of the Invention] The purpose of the invention is to provide a kind of smooth application睥μ f support material is used as a swaying screw for the gorge The ball nut of the (four)-accuracy is not imaged. In the above, the ball nut is slidably disposed on a screw path and has a thread groove, and at least the support member abuts against the lower edge of the screw, and the roll=cap _ The ball nut has an opening σ, the reading member is corresponding to the opening, and the second nut is provided with a thread groove corresponding to the screw groove of the screw, and the thread groove is correspondingly formed to the first ball channel, and the ball nut is disposed at least—the first In the second ball passage, the first ball passes through the second county passage, and the first shape of the passage is less than the first-cycle path. To achieve the above object, a ball nut according to the present invention is slidably disposed on a screw, and at least the support member abuts At the lower edge of the township, the ball nut is characterized in that: the ball nut has an opening, and the branch member is arranged corresponding to the opening. The bearing of the ball nut according to the invention corresponds to the lower edge of the insulting rod. The position of the floor has an opening, so that the position of the ball screw can be avoided to cause a problem of movement inconsistency 'to make the ball nut move smoothly on the screw. In addition, the support provides support for the screw at any time. Make The application process will not affect the process accuracy. 200938751 [Embodiment] The following will refer to the phase of the coffee, according to the ball screw of this distribution, the same components are shown in the butterfly, as shown in Figure 2A and Figure 2B The preferred embodiment of the present invention _ bead nut 22 is applied to - roll _ county set 2. The fleece towel stomach 22 is set on a screw 21 'the screw 21 has a thread groove 211 ' and at least - the support member The force top is applied to the lower edge of the screw 2! In the present embodiment, the plurality of cutting members 23 are taken as an example. ❹ 滚 The ball screw head 22 has an opening σ 〇, and its cross section can be substantially c-shaped or q-shaped. In the present embodiment, the ball nut 22 is exemplified by a C-shape. The ball nut 22 is provided with a thread groove work corresponding to the thread groove 211 of the screw 21, and the thread groove 2U of the screw and the thread of the ball nut 22 are provided. The slot 221 correspondingly forms at least one first ball passage Η, and the ball nut 22 is provided with at least one second ball passage ρ2, and the first ball passage Η and the second ball passage Ρ2 are at least a first-first jujube path u. The plurality of balls B are moved on the first touch path L_. Among them, the second ball channel P2 can be placed in the 22nd wire or the spine 2 thick according to the material. In this embodiment, the balls B are connected in series with a ball cage %, which keeps the balls in the H 24 secret. The support member 23 is disposed corresponding to the opening of the ball nut 22 and is screwed against the screw. The lower edge of 21. In addition, in the embodiment, the support member 23 has at least a roller 231 or at least one ball, and the roller or the ball abuts against the lower edge of the screw, and the rolling member can reduce the bearing member 23 and the screw by rolling friction instead of sliding friction. Friction between. In the embodiment 200938751, the support member 23 is exemplified by having a plurality of rollers 231 as an example. Further, the ball screw device 2 may further include a dustproof member % which is sleeved on the outer surface of the ball nut 22. In addition to preventing dust or foreign matter from entering between the screw 21 and the ball 22, the dustproof member 25 can prevent the ball β from being dropped by the ball_a. ® This is because the ball 22 has an opening 对应 corresponding to the support member 23, thereby avoiding the problem that the ball nut 22 is incoherent due to the position of the support member 23, so that the ball nut 22 can smoothly follow the screw. The movement on the 21 allows the support to provide support to the screw at any time, so that the ball screw device 22 does not affect the process accuracy when the ball nut 22 and the screw Μ are moved. Further, the ball screw device 2 can support the weight of the screw 21 by the support member 23 abutting against the lower edge of the screw cymbal to prevent the screw 21 from being sagged by gravity, thereby ensuring a horizontal state. And when the ball is rolled in the first U-ring path U, so that the support (four) can also be used to support the weight of the screw 22 on the screw 22 when moving along the screw 21. Even if the ball nut 22 is overloaded, the support force is obtained due to the support member 23, so that the thread change line __ of the screw 1 can be avoided. - Bu, by adjusting the water replenishment of the high-freshness fresh screw 21 of the support members 23. The change is shown in Fig. 2 and Fig. 3, which is a different intention of the ball nut of the present embodiment. As shown in Fig. 3-8, in order to increase the number of ball turns between the screw 31 and the ball nut-turn, the ball screw is here to have 4 cores - having a plurality of first-circulating paths, and 〃 one cycle % < For example, it is not intended to limit the invention. In addition, 200938751 =1 lower edge (four) ga wall, butterfly (four) also set dust-proof element as shown in Figure 3B, the monument 4 曰. The two cyclic frequency u, the ζ ^ ball nut 32b are more commonly formed to form at least one of the data designs and the second cycle machine 2 can be second. In this case, the second section of the _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ Shooting need to pay attention, hold the device _, but the actual fine turn ❹ 为 — - ball care option == there are two # _ ball nut corresponding to the top of the screw to the bottom of the screw and ^ open - so can Avoid the movement of the ball nut due to the position of the support _ coherent _ 'Bile ball nut can smoothly move on the screw = Bu, the support is ready to read _ on the screw, and the device is not used with Li Cai. In order to increase the number of balls to increase the rigidity of the green, the circulation paths of the ball nut -, '4 dry can have different design patterns. The above description is for illustrative purposes only and is not intended to be limiting. Any changes or modifications may be made without departing from the spirit and scope of the invention.
