The second problem is that the use of the screw (10) will cause the consumption of the fuel tank (1 2 ) _ lubricating oil. After the oil is used, the user must use the screw (i 〇 The whole root is removed from the machine, the fuel tank (work 2) is removed and the other new fuel tank (i 2) is replaced, and the assembly correction must be repeated. _ It is laborious and does not meet the maintenance efficiency requirements. Therefore, the need to solve the problem of the previous problem is the development of the linear axis roll _ rod is becoming more and more popular and gradually urgency, the easy to listen to the sound, the riding effect is better, the screw is more shameful in the freshest poem _f #点Therefore, there is a kind of US-made industry active product that is more in line with the time when the material is already in the field of development. Improved technology such as profit: 6 1279497 Brother 2 - A drawing of the product is the US patent section 6, 36 side of which the nut (13) and the fuel tank (14) phase screwed on the screw = 14) _ after the instrument (16), the::6) is composed of a body (...), - to the brush ring (162) and - seal 1 6 3 ) (see Figure 2-B), borrowed from the outermost brush ( 16) It can be scraped ice _ i phase (14) of the lubricating oil material is accidentally _ Yu Dan, then the ball screw system must be screwed one by one nut (1w, one oil phase (1 4) and two sides Scraping (1 6 ), not only complicated structure, easy to use, but also many components and high cost of the scraper (16). In order to effectively solve the aforementioned related issues, the creators of the present invention based on the past research and development in the field of linear transmission components (4) Still with experience, from the point of view of the need for excessive electrical equipment repair and processing of the material yard, the development of the threat _ lining the original scraper configuration, saving the space of the fuel tank and improving the maintenance efficiency = run ball screw. The object of the present invention is to provide a kind of kind to avoid affecting the original wiping and crying configuration, and the lubricating effect is good. The above-mentioned purpose is that the lubricating unit is assembled and positioned in the nut, the end of which is exposed to the leaking screw, and the other end of the sliding unit is connected with the hard box, and the lubricating unit absorbs the storage and correction. (10) Lubricating oil; thereby letting the lubrication unit not be accustomed to 1279497 L mesh C 3 G) corresponding to the absorption port (3 2 2 ) at the position of the positioning groove (3 3 )' at the end of the nut (30) Opened to the brush receiving groove (3 4), and the opening (3 2 1 ) of the placement room (3 2 ) is opposite to the brush receiving groove (3 4 ) on the inner side of the nut (30); The lubrication unit (4 〇) is embedded in the placement space (32) of the nut (30), and the lubrication unit (4〇) is provided with a protrusion (4 1 ) at one end of the lubrication unit (4 )) (4 1 ) protruding from the opening (3 2 1 ) of the placement space (3 2 ) and the protrusion (4 1 ) correspondingly contacts the screw (2 〇), and in the &quot;Heil Run α unit (4 〇) There is an absorption part (4 2) at the absorption port (3 2 2) of the space (3 2 ); the oil storage tank (5 〇) is filled with lubricating oil and the oil storage tank (5 〇) ) 疋 position on the nut (3◦) side The oil storage tank (50) is disposed in the positioning groove (3 3) at the corresponding absorption port (3 2 2 ) of the nut (3 〇) by using the protruding sleeve joint (51) of the output lubricating oil material. The protruding sleeve joint (5 1 ) abuts against the absorbing portion (4 2 ) of the lubricating unit (4 〇), and the quick release of the dodging screw (2 〇) is opened on the side of the oil storage tank (50). Capacitance (5 2) (making the oil storage tank (5 〇) in a horseshoe type), and the quick release opening (5 2 ) allows the screw (20) to pass radially; the second scraper (60) is embedded Positioned in the wiper receiving groove (34) at the end of the nut (3 ;); the above is the relationship between the related components of the present invention and its general 1279497 to V run β early 7G and At least _ external storage tank, the inside end of the lubricating nut is exposed to the contact screw, and the lubrication is connected, and the unit is absorbing and replenishing (4) lubricating oil, and the quick release port 1 for allowing the scale to pass is opened. One side r, 廿曰, 明 π 猎 决 拆 可 可 可 可 可 可 可 可 可 可 可 可 可 可 可 可 可 可 可 可 ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' The utility model can effectively save the space of the oil storage tank, simplify the product design and improve the maintenance efficiency; therefore, the "availability of the linear transmission component production=" of the present invention should be undoubted, in addition to the features revealed in the embodiment of the present invention. The technology has not been seen in publications before the application, nor has it been used publicly. It has the fact that the above-mentioned effects are enhanced. Therefore, the "novelty" and "progressiveness" of the present invention have been in compliance with patent regulations. The application for the invention patent, pray for the review and early grant of the patent, the real sense of virtue.
