Description of the invention: [Technical field of the invention] Structure of single screw arrangement The present invention relates to a roller screw for linear transmission, in particular to a complex spiral with a complex spiral on a mating single-nut Design. [Prior Art] According to the 'precision machine wealth, there is often a need to control the working platform or the machining miscellaneous movement. In order to control the moving feed amount with precise and small friction coefficient, the movement is performed with two screws. The New Screw type shirt, but both are used with - screw sleeve - or two nuts, the thread groove between the screw and the nut and the complex roller 'money structure' design are mainly as follows Species: A. For the use of - screw fit - nut and each set - the design of the thread groove, and in the complex parallel system in the observation, the use of this single - viewing groove, all the miscellaneous; wire direction and Shaw When you are lying down, you can only use the roller to move on the unilateral side of the thread groove. The force of this type of finance can only withstand the load of a single spoon. Machine 纟 (for example: injection molding machine, nuclear machine, etc...). B. In order to utilize the - screw fit - nut and each set - the structural design of the thread groove, and the threaded projection is placed on the side of the rolling contact, the column is arranged in a staggered manner, although the average force and bearing can be achieved. The purpose of the two directions of force, but 5 1341908 mother-direction can withstand the force of the f roller only _ amount of - half (because the roller crosses 歹i)) so there is still a lack of load capacity, that is, no good.

In order to utilize a screw to match the two nuts and each of them is provided with a thread groove, and the plurality of parallel (four) are in the thread, the use of the single-thread groove with the second nut is set separately. The miscellaneous cycle of different tilting degrees of rolling, in this way, the rolling field rod has the effect of two financial forces, but this is a double nut = ° again. The overall length of the ten snails in the snails is also relatively long on the screw, so that the thread on the screw is short. If the problem is to be solved, the screw _ length must be increased, and the cost of the k and the material cost are increased. The contact surface between the two nuts requires a high surface precision and parallelism, so it is necessary to manufacture the high-precision standard of the wire-making process by the high-precision standard of the wire-making, and the design of the double nut. The assembly work is also very complicated, and it takes a relatively long assembly time, so the aforementioned problems increase the manufacturing cost of the design of the double nut. :::::::::[Inventive content] Technical problems to be solved: The conventional screw with the nut for rolling _ the design of the two-direction force is to use a screw fit: the structure of the roll The column can withstand the rolling of the roller without setting the angle of the slanting angle. The 2 nut's are respectively supported by the rollers on the nuts of the two nuts, and the forks of the different directions are 6 i34l9〇8, and the structural design can be improved. Load capacity (rigid), but the design of the double nut will make the overall length of the nut longer, the movement of the nut on the screw is shortened, and the contact surface between the nuts requires a higher surface. Accuracy and parallelism also have the problem of difficult processing and high processing cost, and also require a long time to assemble. This is a technical problem to be solved. Technical Problem for Solving the Problem: The present invention provides a roller screw with a plurality of reflow devices and a plurality of spiral grooves, comprising: a screw surface having at least two spiral grooves; and a nut having a groove opposite to the screw; Inside and outside (4), the wall thickness is provided with a receiving hole ', and the end of the hole is placed. [5 sigh has a fixed groove; a plurality of rollers are arranged in the groove between the screw and the nut; and a reflow device of the number of the spiral groove, the reflowing skirt has an opening at both ends; a track is formed between the two openings; thereby Each of the reflow cracks and the snails are connected to the (4) different snails from the two connected snails, so that each:::, the reciprocating flow of the roller-single-circulating flow formed by each reflow device is compared with the prior art. Efficacy: The purpose of this I is to provide a complex reflow device with a screw, the use of the screw-to-spinner π is a number of screw-corrected rollers placed two reflow screws to match the early one nut, and the nut is placed The first-shun after the second job slot. And the 7-four-one spiral groove and the 7-inch 341908 second spiral groove are cyclically connected to each other, so that the screw and the nut return to the roller in a single cycle, and the roller is generated in different spiral grooves. Different steering 'bearing two-way load' has better performance and doubled load capacity. In addition, 'reflow is made up of each opening on the two ends of the reflow device and one between the two openings. The advantages of simple design, convenient processing and assembly do not require very high precision machining and assembly.
