Description of the invention: [Technical field to which the invention pertains] The invention relates to a type of outer helium ring type ball screw circulating type ball screw.曰[Prior Art] I have more and more applications of the ball screw in the industrial field. In addition to the high precision effect of the #^进进传(4), the other has a small friction loss rate, high energy conversion rate, and arpeggio. The advantages of small and high rigidity are not easily damaged, and therefore, the importance of the ball screw for various industrial applications and tools today is not to be understood. In order to allow the nut to reciprocate on the screw indefinitely, it is necessary to provide a reflow device. The rolling element can be circulated infinitely in the rolling groove #, and the conventional design of the reflow device is as follows: US patent In US3661030, etc., the return path of the reflow device will have a bend. When the rolling element is in the case of idle running, the bending point of the impact finger and the return path (the slamming point) is constantly caused, so that the finger and The strength of the impact is gradually weakened, and the entanglement of the reflow elements that are peeled off by the impact is caused by the inclusion of the rolling elements, and the smoothness of the rolling element circulation is caused, so that the destruction of the reflow device is one of the quite common failure conditions of the ball screw. . 5 1314620, then 'the current industry to solve the above problems, the method of the .f tube from the tangential direction into the thread of the design, such as, US patent uS3971264 reflow device design, its f tube because of the combination of its structure " :, and the direction of the tube hole of the nut is the direction of the lead angle. Therefore, the position of the multi-axis machine rotating nut should be used for the tube hole working time, so that the hole can be processed to the hole position, so the processing difficulty of this item will be And the U.S. Patent No. 4,953,419 reflow device has a two-bend guide channel 5, so that the bending portion is difficult to control in manufacturing; and the problem of the processing method of the nut hole of the nut is The above patents are the same 'and the fixing method of the reflow device is fixed by the fixing piece on the outer diameter of the outer diameter, the fixing manner thereof is relatively unstable, and the outer diameter of the nut is increased, and US Patent US 2003/0213323 The reflow device is composed of a plurality of components combined, and a plurality of molds are required to reflect the component requirements, thereby causing an increase in the mold design cost, and the Lang flow device is designed in a combined manner. Also, when the number of components required for the reflow device is increased, the internal rolling elements of the reflow device are likely to cause vibration between the components when moving at a high speed, thereby generating unclear noise. In addition, the above three conventional tangential recirculations The device has a common problem, and it is not easy to align when the reflow device is mounted on the nut, and the rolling member is easy to fall when the step of filling the rolling member. 1314620 [Summary of the Invention] The problem has been solved by the inventors of the present invention, which has finally achieved the object of achieving the following invention. That is, the primary object of the present invention is to make the tube hole of the nut easy to process without using special machinery (for example, The shaft processing machine can be processed, and the reflow device is advantageously manufactured. The secondary object of the present invention is that the reflow device is assembled in the nut position (four) and is easy to load the rolling member to shorten the dressing time.

After the perforation of the fixing portion is passed through the fixing member, the screw hole of the guiding member is fitted and fixed, and the covering member is covered on the guiding member, that is, the assembly of the reflow device is completed. In the above, by the cooperation of the mounting hole and the guiding portion, and the fixing and fixing of the fixing member and the screw hole, the reflow device can be firmly mounted on the nut. In addition, it is worth mentioning that, by the design of the guiding member and the rolling groove and the rolling groove, when the rolling member is filled, the rolling member is filled by guiding the guiding member. Between the rolling groove and the rolling groove, the covering member can be covered on the guiding member after filling, so that the filling time of the rolling member can be shortened. The reflow device can be mass-produced by means of mold injection. The design of the mounting hole of the nut can be processed by using a general processing machine, and the machining accuracy of the mounting hole is improved by the planar design. 8 13 146 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 Do any restrictions*.
