In addition, the ball screw group 妒昉: the labor is more complicated, so the cost is also higher. 1273189 V. Invention description (2) In the inner diameter of the nut, the tooth can be applied to the end of the sale 2 placed into the ball and then screwed into the screw, The screw needs to be used and the base is reflowed. Comprehensive, ten, and necessary. The traditional ball screw end plug reflow method is improved. [Inventive purpose] It provides a nut rolling element recirculating device for the direct purpose, and the nut body of the screw is 7 bolt body, so that the nut can be assembled directly. It is not out and the processing complexity of the nut body is reduced. SUMMARY OF THE INVENTION The nut is sleeved on the screw to produce relative movement. The main invention of the nut is intended to utilize the advantages of various cycles. The outer circulation of the screw does not require the high lead characteristics of the teeth, the inner and the end plug cycle. Inventive research is to return the nut rolling element, and the thread of the reflow mode has an axial return to the return hole of the nut body, and the radial hole groove is radially inserted into the outside of the nut body to be placed in the reflux device. When rolling into the screw, the rolling element is placed in the reflow device. This design can be rolled between the two to include the nut body and the reflow device. This design has a reflow device, such as: The easy-to-machine nut method of the cycle, the end cap and the end plug type of mute effect, and the like. The manner in which the body is axially reflowed through the through hole is such that the nut body does not interfere with the internal thread except that it has an inner through hole in its inner diameter. Then, the circumference of the circumference is provided with a plurality of radial holes, the inner and outer diameters, so that the nut body can be directly assembled into the screw body and the nut body when assembling the nut body of the nut body, and then the screw does not need to be toothed. And this kind of back

INSTRUCTIONS (3) _ The flow-type nut body does not need to be reworked. The nut body is threaded through the radial hole groove to install the m-groove, and only the reflow device of the present invention is opened; Two u it is easy to process. The main shaft is formed into a slightly curved arc-shaped L-shaped body. The path is in the radial hole groove to connect the nut body piece, and the flow device is provided with a turning surface and a returning core hole. The hole's returning device is provided with a guiding piece for connecting the inner threaded path, and the returning path is such that the rolling body has a complete f.Μ guiding rolling element to enter the steering reflow device and is formed on the path of the body The groove is matched to the hole, and the remaining ruler:: the matching precision of the 鳊 and the main body of the spigot, so the better processing of 2 i R is not required and the snail is further, because of the basic reflow path of the present invention, The flow path, the rolling body is rotated from the inside of the nut body to the backflow system, and the W is connected to the impact guiding piece:::, the direction of entering the sound value is also lower; and because of the invention The steering path is second, and the degree is better and "the turning surface and the return through hole are synthesized' and the reflow device of the present invention rotates: the smooth surface is curved at one end and is designed to be flat with the return through hole. , the end of the black ^ is the extension of the internal thread tangential line of the nut body, in the internal thread of the force body, The guide bow of the reflow device is cut behind the snail of the snail, and the steering surface of the sluice device is deflected along the recirculation device, 7 W is taken into the escape and enters the turning surface. The steering path combined with the return through-hole is transformed into a complete return through-hole in a straight line. Then the reflow device is designed to make the rolling elements smoother. In addition, in order to improve the group of the reflow device of the present invention to the return through hole. 1, more profitable, can also be set
