New description: [New technical field] There are some kinds of ball screw components used in linear transmission. The ball screw-brush structure can be improved. There is a need to control the working platform or processing components to move the second (four) 4 months " accurate and small friction coefficient of the mobile feed I; a = using the ball screw for precision _ transmission, and the ball screw and a nut, In order to reduce the generation of friction, the snail complex ball cooperates with the 'ball and must be able to roll inside the nut'. The cycle rolling is performed by setting the circulation system on the nut. (4) When the ball screw is used, in order to avoid foreign matter such as debris or dust, the door between the screw and the nut is _ into the inside of the nut, interfering with the rolling ball of the screw, so that the ball does not smoothly roll when it is snail Each of the two ends of the cap is provided with a brush to the brusher. The brush is annular, the center of the brush has a punching hole, and the inner wall surface is formed with a plurality of radially protruding ribs, and each rib can be Into the screw = spiral groove; only 'the conventional wiper has the function of scraping off the screw on the chip or dust foreign matter' but the brush is usually not able to properly contact the circumference of the screw:: spiral groove, not When there is a gap, there is an urgent state. ...The screw cup is not in an ideal state, because once the gap occurs, the effect of scraping off foreign matter such as slag or dust is not good. On the contrary, the pressing force will cause the ball screw to be blocked. No (four). H [New content] M404908 The creator has a good understanding of the structure of the scraper of the ball screw, w (four) in addition to reducing or tampering; smooth = problem arises - is the creation of The idea, after many discussions and trial sample tests, and many corrections and improvements, finally launched this creation. The present invention provides a brush screw structure of a ball screw, wherein the ball screw is formed by a nut and a screw sleeve, and a spiral groove is arranged on the screw and the nut respectively to accommodate a plurality of balls. Circulating and recirculating between the screw and the nut 'to the brush is a ring-shaped piece, set on the nut two; the surface 'the center of the brushing ―-axis hole, the axis hole is surrounded by a spiral The diameter of the convex portion 'the axial hole is the outer diameter of the screw plus the diameter of the ball ι/ι〇, and the inner diameter of the spiral convex portion is the groove bottom diameter of the screw spiral groove plus g. 5]% groove bottom diameter: In use, the inner edge of the shaft hole of the wiper and the spiral convex portion appropriately abut against the peripheral surface of the rod and into the spiral groove to perform a wiping operation. The main purpose of this creation is to have a ring-shaped piece to the brush, a middle shaft hole with a hole diameter of the outer diameter of the screw plus a ball straight through 1/1Q, and an inner diameter at the inner circumference of the central shaft hole. For the bottom diameter of the spiral groove of the screw, the spiral protrusion of the bottom diameter of the groove is added, and when the (four) shot is used, the inner edge of the hole appropriately abuts against the peripheral surface of the screw, and the spiral convex portion is appropriately fitted into the spiral groove of the screw. 'Make the secret of the system more accurate, ambiguous, and the result of the increase. [Embodiment] In the following, the preferred embodiment of the present invention will be described in detail with reference to the drawings, and the three-dimensional exploded view of the created ball screw, the second figure of the original scraper, and the third figure are created. The plan view of the scraper, the fourth M404908, the three-dimensional cross-sectional view of the created ball screw, and the fifth figure, the schematic diagram of the scraping brush of the created ball screw, the inventive ball screw system comprises: a screw 1 having a surface provided thereon a spiral groove u; a nut 2 having a spiral groove 21 opposite to the screw; a plurality of balls 3 disposed between the spiral groove of the screw “ and the spiral groove 21 of the nut; two squeegees 4, the brush 4 is an annular sheet body, which is disposed on both end faces of the nut 2 for threading the screw, and the center of the scraper 4 is provided with a shaft * hole 41, and the inner edge of the shaft hole 41 is provided with a surrounding spiral convex portion 42. The aperture R of the shaft hole 41 is 1/1 〇 of the outer diameter of the screw 1 plus the diameter of the ball 2, that is, the sinusoidal aperture R of the shaft hole 41 is larger than the outer diameter of the screw 1/ 1/1 直径 of the diameter of the ball 2, the spiral The inner diameter R' of the convex portion 42 is the bottom diameter of the spiral groove 11 of the screw 1 plus 0. 5~1 % of the bottom diameter of the groove, that is, the spiral The inner diameter R of the portion 42 is .01 times the groove bottom diameter of the screw 丨 helical groove u, and the central shaft hole 41 and the spiral convex portion 42 of the wiper 4 appropriately abut against the peripheral surface of the screw 1 and the screw 1 is abutted. In the spiral groove, when the ball screw is actuated, the screw 丨 rotates, and the ball 3 circulates back and forth between the spiral groove 11 of the screw i and the spiral groove 21 of the nut 2, and the snail φ cap 2 smoothly performs linear motion. And the inner edge of the central shaft hole 41 of the brush, 4, which is disposed on both end faces of the nut 2, scrapes foreign matter such as debris or dust on the peripheral surface of the screw cymbal, and the spiral convex portion 42 of the wiper 4 The inner edge is to the foreign matter such as debris or dust in the spiral groove of the brush screw 1 to ensure smooth rolling of the ball. According to the structure of the above specific embodiment, the following benefits can be obtained: the center of the wiper 4 has a shaft hole 41 having an aperture R of an outer diameter of the screw 加上 plus a diameter 1/1 of the ball 2, and an inner edge of the shaft hole 41. The inner diameter R' is the groove bottom diameter of the screw 丨 spiral groove 加上 plus 0.5 to 1% of the groove bottom diameter of the spiral convex portion 42, and the inner edge of the shaft hole 41 is in contact with the periphery of the screw 1 when in use. The surface of the spiral groove 11 is inserted into the spiral groove 11 of the 5 M404908 screw to form a tight fit of the appropriate compression n without interference, so that the wiping action of the wiper 4 is more surely improved. (4) Only, smooth, 'scratch brushing efficiency, as described above, this creation has indeed reached a breakthrough structure, and has improved content of creation, while at the same time being able to achieve industrial use. = When complying with the provisions of the Patent Law爰Proposed a new type of patent application according to law, and the board of directors of 恳^ granted legal patent rights, and was praying.
