Description of the invention: [Technical field to which the invention pertains] The invention provides a new structural design in particular to a loop-type ball-guiding screw set, thereby achieving a bottleneck of easy processing technology and being able to grow nuts The length requirement =, the complex = the degree is still unchanged, and the required length can be quickly completed. When the bearing strength of the screw cup group is not placed, the processing cost is not increased. [Before the technology] In the structure, if the fixing nut does not rotate when the screw rotates, the screw stomach can be swayed by the front and the moving structure, and the guiding structure 1 is affected by the addition of 1 gap: = rotation, an idle gap is generated, and Affecting the accuracy of the moving distance = stability, so there is still the development of the ball lead screw group, such as the first, second, and the display, the ball lead screw group mainly uses at least one nut 1 〇 through the jinning rolling element 25 is screwed into the screw shaft 2〇, and is used by the rolling rolling element 25 to make the nut 10 and the screw shaft 2 〇 relatively smooth, and has excellent smoothness and precision, so it is widely used in the species. Machines that require precision movement; Because of the need for precise sliding relationship, the spiral groove η in the general nut 1 needs to be ground, but it is limited by the size and fine parallelism of the processing tool, and the nut 10 is added in the grinding spiral groove u. The limitation of the nut makes the length of the nut 10 relatively limited. For example, although the length of the nut can be slightly increased, the length of the nut 10 can be increased, and the processing equipment is expensive, and the skilled person is required. Iy / = can =: increase:: = work, production, high, non-performing rate:: competitiveness 'and can not meet the larger two or more nuts to send plus ', due to long-term interaction with rolling elements wear Moreover, the difference between the two is greatly increased, which is called the gap or backlash, one; as i, the nut and the roll: -::::: plus: ^^ : Yes: Field: Help :.
