Description

本発明はねじロッドに係り、特に装置の固定に用いられる潤滑装置を有するねじロッドに関するものである。 The present invention relates to a threaded rod, and more particularly to a threaded rod having a lubricating device used for fixing the apparatus.

ボールを有するナット回転式のねじロッドは、ナットとベアリングの外部リングを一体に形成させ、該ベアリングの外部リングは作業ベースに固定され、モータがベルトで動力をナットに転送することにより、ナットとねじロッドを互いに回転させながら、作業ベースを連動する。このようなねじロッドは、半導体機械、木工機械及び搬送装置などに使用されるので、現代工業の機械にとって非常に重要である。 A nut-rotating threaded rod with a ball integrally forms a nut and an outer ring of the bearing, the outer ring of the bearing is fixed to the work base, and the motor transfers power to the nut with a belt, thereby The work base is interlocked while rotating the screw rods. Such threaded rods are very important for modern industrial machines because they are used in semiconductor machines, woodworking machines and conveying devices.

一方、アメリカ合衆国特許第５,８０９,８３８号及び第６,７３２,６００号では、ボールを有するナット回転式のねじロッドに用いられる潤滑装置が開示されている。図５に示すように、このような潤滑装置の潤滑方式では、外部リング（９４０）に外部の潤滑装置とベアリング（９４）の内部に連接する貫通孔（９４１）が形成されると共に、ナット（９２）にも貫通孔（９４１）と対応する貫通孔（９２１）が形成されることにより、潤滑油がナット（９２）の内部に流れ込みながら、ねじロッド（９１）とボール（９３）を潤滑することができる。 On the other hand, US Pat. Nos. 5,809,838 and 6,732,600 disclose a lubricating device used for a nut rotating screw rod having a ball. As shown in FIG. 5, in the lubrication system of such a lubrication apparatus, the outer ring (940) is formed with a through hole (941) connected to the interior of the external lubrication apparatus and the bearing (94), and a nut ( 92) is also provided with a through hole (921) corresponding to the through hole (941), thereby lubricating the screw rod (91) and the ball (93) while the lubricating oil flows into the nut (92). be able to.

しかしながら、上記の従来の潤滑方式には、以下のような問題がある。 However, the above conventional lubrication system has the following problems.

１.ナット（９２）と外部リング（９４０）に加工を行うことがあるため（特にナットのねじ溝（９２０、Ａ）の加工は、ねじロッドの強度を大幅に降下してしまう）、構造強度を降下する問題がある。 1. Since the nut (92) and the outer ring (940) may be processed (especially, the processing of the screw groove (920, A) of the nut significantly reduces the strength of the screw rod), the structural strength There is a problem of descending.

２.潤滑油がナット（９２）の全ての内部空間に充填すると、潤滑効果が出るので、潤滑効果を達成するかどうか確認できない（即ち、強制注油必要がある）。 2. When the lubricating oil fills all the internal space of the nut (92), a lubricating effect is produced, so it cannot be confirmed whether the lubricating effect is achieved (that is, forced lubrication is necessary).

更に、一般のボール付きねじロッドに用いられる潤滑装置は、例えばアメリカ合衆国特許第６,３６４,０５８号に開示されるように、ナットの一端に、内部に潤滑油を収容する油室と、ナットと接触する潤滑装置が設けられることにより、ナットを潤滑するが、ボールを有するナット回転式のねじロッドに使用できない。これは、油室がナットと同時に回転するため、潤滑油を強制給油できず、有効的に潤滑することができない。
アメリカ合衆国特許第５,８０９,８３８号 アメリカ合衆国特許第６,７３２,６００号 アメリカ合衆国特許第６,３６４,０５８号 Furthermore, as disclosed in, for example, U.S. Pat. No. 6,364,058, a lubricating device used for a general threaded rod with a ball includes an oil chamber for containing lubricating oil therein, an nut, and a nut. Although the nut is lubricated by providing the contacting lubrication device, it cannot be used for a nut-rotating screw rod having a ball. This is because the oil chamber rotates simultaneously with the nut, so that the lubricating oil cannot be forcibly supplied and cannot be effectively lubricated.

The lubrication effect is achieved by flowing into the threaded rod (1) from the holes (324A) (324B). The flow rate of the lubricating oil (6) is determined by the dimensions of the oil outlet holes (324A, 324B).
