In order to allow the balls between the screw and the nut to circulate continuously and relieve stress, the ball screw of the screw and the nut can be equipped with a reflow element at the screw end and the ball at the two ends of the nut; It is the key to let the internal ball of the ball screw move between the screw and the nut and then reflow. Therefore, how to develop and improve the more competitive products for the reflow component has become the focus of the industry. In the past, the reflow elements used and recognized by many people can be divided into two types depending on the installation method. One is the axial installation method (as shown in Figure 1), and the other is the radial installation method (not shown). For the following description, please refer to the following description. · "Axial Mounting Method" 1274815 Figure 1 is US Patent No. 4,357,838, which uses a ball screw with an axially mounted reflow element, which includes a nut (1 〇) and a screw ( 1 1 ), most of the balls (1 2 ) and the axially mounted reflow element (1 3 ), the reflow element (1 3 ) is designed to be mounted from the end face of the nut (i 〇), through the installation of private decay beads 2) The reflow element (i 3) at the end of the path feeds into the return hole (not shown) of the nut (1Q), and the oil on the reflow element (13) is a very important part in the industry. (14), the nail (14) is mainly designed to span the nut (1 〇) of the screw 'by the reflow element (i 3) integrated nail (14) can be. _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ The silk-based products still have the following problems in the real secret: 纟—, such a ton component (i 3 ) has a health supplement, The advantage of high speed operation, but since the nail (14) is embedded in the screw channel (101) of the screw (11), it is customary to install a reflow element (work 3). ) The end of either end of the threaded channel (i 〇i) must be open = (the industry is known as the teething design), so that the conventional screw (the shoulder of the production must also have a tooth design). At present, the screw (will leave a gap on the bearing surface of the shoulder of the screw (11), the diameter of the abutment surface of a is non-integrity, and f makes the shoulder bear on the machine table _ bearing (not both ends are Installation. The two ends of the axial force generated by inertia will be unevenly distributed due to the non-integrity factor of the bearing 274815 due to the non-integrity of the diameter of the bearing 274815, except for the installation of the load (螺杆1). In the machine (4) bearing _ bearing end face (not =) caused by crush damage, and then the screw (in the running state & • the phenomenon of line bending deformation) not only directly shadow (four) reflow group (four) ring smoothness, more Will reduce the service life of the bead screw; Second, the conventional technology is to first screw (i i) Wear the appropriate position on the nut (丄〇), and smoothly place all the balls (1 2 > use the screw 0 1) and the nut (1◦), and then the ball (12) It is only possible to let the skilled assembler load the reflow element (13) at an appropriate angle. (1) 曰曱 (1 4) If it is not forced at an appropriate angle, it will be difficult to assemble successfully, due to the nail (14) It is easy to interfere with the assembly work of the screw (1 1) and the nut (1 ◦). The time required for the assembly process is more expensive. Under strong installation, the reflow element (13) may even be damaged. "One field screw (1) 1) Both ends are mounted on the bearing housing of the machine #日='Group t will first thread the screw (2 i ) into the nut (丨q) and fill in ^ 2 ) Manually as the ball screw set |In the assembly process, it is necessary to cooperate with the adjustment and adjustment steps. Because of this step, the nut (10) is separated from the screw (11) or the [super 匕仃 _ ' leads to the ball (1 2 ) accidentally spun out of the drop. "Radial Ankle" 1274815 Due to the aforementioned problems, another radial mounting method appeared on the market, which is attached to the outer hole of the nut (radial), and the reflow element is passed directly when shouting. Installation, this wire-oriented method can not only solve the problem of matching the nails of the component and the screw screw, but it will still extend other problems: -, - because the radial opening will cause the nut to lose its closeness, and The ball rolling and shouting is unremarkable, and the ball noise that affects competitiveness is generated. • The second reflow element that is placed from the radial opening of the nut is not installed in the axial direction. It may also be due to the earthquake _ big secret, Yan Lin will be like a ball screw structure. In order to effectively solve the above-mentioned related issues, the creator of the present invention has finally developed a brand-new ball screw based on the research and development of the field of ball in the field of ball in the past, from the point of increasing assembly strength and ease of assembly and disassembly. Segment φ component. SUMMARY OF THE INVENTION The main purpose of the present invention is that a reflow element provides a ball screw with an unrestricted teething design which achieves the above object. The ball screw segment reflow element of the present invention consists of an internal reflow and an external component. (4) The county, the bead screw segment reflow element can be placed on the screw and nut before the nut and the screw element can be placed in the nut assembly. In order to avoid the interference of the beads or the screw, the ball and the screw element are installed in the ampule field, and then the nesting combination of the reflow block in the unsealed nut is fixed, and the outer reflow block is fixed on the nut; thereby, the invention The ball screw segment reflow element uses the combination of the first and the remaining loading technology (4) to avoid the interference of the beads or the screw, which is more effective in solving the limitation that the screw itself must have teeth. ▲ The secondary object of the present invention is to provide a ball screw segmented reflow element which is easy to assemble, stable in the gorge style, and capable of maintaining low chewing characteristics; when the screw of the invention material is assembled and disassembled, the private-purpose ball screw is generally ^ When reflowing 70 pieces, it is necessary to simultaneously deal with the problem that the reflow element nails are easy to interfere, and T uses a segmented structure to eliminate spatial interference, which effectively simplifies the assembly procedure and time. In addition, the sub-bead screw segment reflow elements are each other and locked by a lock. The fittings are locked in the second one, and the locking method is stable, and the nut can be sealed. The utility model can effectively maintain the low noise effect. ^Ben Hongming is better at achieving the above objectives, the techniques, methods and other methods. The embodiment is described in detail with reference to the drawings, and it is believed that the purpose of the invention, the furnace, the "and other advantages can be obtained from the depth of the invention.
