New description: [New technical field], the system is related to the ball screw component used in linear transmission, especially a ball screw scraper knot which can improve the brush effect. [Prior Art] Precision machine money often needs to control the guard platform or the processing component shift = 4 ' and in order to control the mobile feed with precise and small friction coefficient \ the movement is carried out with the ball screw for precise transmission, and the ball screw is provided with - Screw and a nut, in order to reduce the friction, the screw and the nut are used with a plurality of balls to cooperate with the 'balls and must be able to repeat the cyclic rolling in the nut, which is completed by using the setting circulation system. . When the ball screw is used, in order to avoid foreign matter such as scraping or dust, the ball between the screw and the nut enters the nut and interferes with the rolling of the ball in the nut, so that the ball does not flow smoothly, but Each of the two ends of the nut is provided with a _ a wiper'. The brush is annular, and the center has a shaft hole. The inner wall of the basin is formed with a radially convex rib, and the rib can be embedded. The spiral groove of the screw; however, although the conventional wiper has the function of removing foreign matter such as slag or dust from the screw, the wiper usually cannot properly abut against the peripheral surface of the screw and into the spiral groove. It is not a void. It is an urgent state. It is not ideal for a ball screw. Because if a gap occurs, the effect of scraping off foreign matter such as debris or dust is not good. Conversely, the pressing state will cause the ball screw to be blocked. It is not smooth. [New content] 3 Oblique U49〇9 This creator has the advantage of knowing the structure of the ball screw to the brush, so it is good, but it is easy to scrape off or cause the rotation to be unsmooth. 1 Interview and creation (4) After reading the "multiple-party discussion and trials... test, and many revisions and improvements, I finally launched this creation. It is composed of i = kind: t screw _ structure, its ball screw right η, mesh..., #phase sleeve & 'and on the screw and nut respectively and spiral groove' to accommodate a plurality of balls on the screw and The damper between the nuts is a ring-shaped body, which is arranged on both ends of the nut = the wall surface of the brush (four) is provided with a radial (four) convex ring, and the extension has a convex portion, and the convex ring The inner diameter is the outer diameter of the screw minus 1/10 of the ball diameter. The offset of the convex part is 1/6~2/b of the ball diameter and the ball is directly committed by the ball/3, and the The main purpose of the peripheral surface of the brush ring rod and the screw groove is that the inner end of the inner wall surface of the brush is provided with an inner t for the outer diameter of the screw minus 1/1 () the diameter of the ball ± 5% of the convex ring, and the convex ring edge - side is provided - offset ball diameter 1 / 6 ~ 2 / 1 distance formed by the convex. In the case of using P, the inner edge of the convex ring is appropriately in contact with the peripheral surface of the screw, and the convex portion is appropriately irradiated to the screw of the screw, so that the wiping action is more accurate and smooth, and the wiping effect is improved. [Embodiment] The following is a detailed description of the preferred embodiment of the present invention. The three-dimensional exploded view of the created ball screw, the second figure of the original tongue brush, and the third figure are created. The plan view of the wiper, the fourth view of the creation of the ball screw, the perspective view, the fifth picture of the creation of the ball screw. The schematic diagram of the scraping brush of the created ball screw is shown in the figure of j and the sixth figure. The ball screw system of the present invention comprises: a screw, and the surface thereof is provided with a screw 钇 11, a nut 2, and a screw 丨The spiral groove 21 is opposite to the spiral groove 21; a receiving hole 22 communicating with the inner perforation, the reflow element receiving group ax, the plurality of balls 3, the spiral groove 1 of the screw 丨 and the spiral groove 21 of the nut Two scrapers 4, the wiper 4 is a ring-shaped body, and is disposed on the two sides of the nut 2, for the screw 1 to be worn out, and the end of the inner wall of the brush 4 is provided with a radial convex The convex ring 41 is extended from the inner edge of the convex ring 41 by a convex portion 42. The inner diameter r of the convex ring 41 is the outer diameter of the screw 减 minus 1/1 〇 the diameter of the ball 2 5% 'the offset L of the convex portion 42 is 1/6 to 2/1' of the diameter of the ball 2 and is preferably 1/3 of the diameter of the ball 2, and the convex ring 41 and the convex portion 4 of the wiper 4 2 appropriately abuts against the peripheral surface of the screw 1 and into the spiral groove 11 of the screw 1. - When the ball screw is actuated, the screw 1 rotates, the ball 3 is circulated and recirculated between the screw groove 11 and the spiral groove 21 of the nut 2, and the nut 2 is smoothly linearly moved and assembled in the The inner edge of the convex ring 41 of the wiper 4 on both end faces of the nut 2 scrapes foreign matter such as debris or dust on the peripheral surface of the screw 1, and scrapes the spiral groove η of the screw 1 with the inner edge of the convex portion 42 of the wiper 4. Foreign matter such as crumbs or dust to ensure smooth rolling of the balls. According to the structure of the above specific embodiment, the following benefits can be obtained: one end of the inner wall surface of the wiper 4 is provided with a convex ring 41 having an inner diameter of an outer diameter of the screw 1 minus 1/1 〇 the diameter of the ball 2 by ±5%, and A convex portion 42 extending from the inner edge of the convex ring 41 by a center shifting ball 2 by 1/6 to 2/1 is provided, and the 5 M404909 is tightly fitted and smoothly used. The inner edge of the convex ring 41 abuts against the peripheral surface of the screw 1, and the portion 42 abuts into the spiral groove n of the screw 1 to form a proper compression without interference, so that the wiping action of the wiper 4 is more accurate. The effect is improved. In summary, this creation has indeed reached a groundbreaking structure, and has improved content of creation, while at the same time being able to achieve industrial use and progress. When complying with the provisions of the patent law, the table proposes a new type of patent application according to law. The census review committee granted legal patent rights and was praying.
