As shown in FIG. 1, the ball screw device 1 includes a screw shaft 2 as a first member and a nut 4 as a second member screwed to the screw shaft 2 via a plurality of balls 3. ing.
　ねじ軸２は、細長い円柱形状の金属製部材からなり、このねじ軸２の外周面には、断面が略円弧形状のねじ溝２ａが螺旋状に形成されている。 The screw shaft 2 is made of an elongated cylindrical metal member, and a thread groove 2a having a substantially arc-shaped cross section is formed on the outer peripheral surface of the screw shaft 2 in a spiral shape.
　ナット４は、ねじ軸２の外径よりも大きな円形の貫通孔が形成された略円筒形状の金属材料から成形されている。ナット４の内周面には、ねじ軸２のねじ溝２ａに対応するように、断面が略円弧形状のねじ溝４ａが螺旋状に形成されている。 The nut 4 is formed from a substantially cylindrical metal material in which a circular through hole larger than the outer diameter of the screw shaft 2 is formed. A thread groove 4 a having a substantially arc-shaped cross section is formed in a spiral shape on the inner peripheral surface of the nut 4 so as to correspond to the thread groove 2 a of the screw shaft 2.
　ねじ軸２はナット４の上記貫通孔に通されており、互いのねじ溝２ａ、４ａが対向してボール３の転動路を形成している。この転動路内には、金属製の複数のボール３が装填されており、これによってねじ軸２とナット４は螺合している。 The screw shaft 2 is passed through the through hole of the nut 4, and the thread grooves 2 a and 4 a face each other to form a rolling path of the ball 3. A plurality of balls 3 made of metal are loaded in the rolling path, whereby the screw shaft 2 and the nut 4 are screwed together.
　ナット４の両端の開口部には円形に凹部９が形成され、この凹部９にリング形状のシール部材６が嵌め込まれている。このシール部材６の内周面がねじ軸２の外周面及びねじ溝２ａの面を摺接することによりナット４とねじ軸２との間に異物が侵入しないように構成されている。ナット４のフランジ部４ｂにはグリース供給口８が設けられている。 A circular recess 9 is formed in the opening at both ends of the nut 4, and a ring-shaped seal member 6 is fitted in the recess 9. The inner peripheral surface of the seal member 6 is configured to prevent foreign matter from entering between the nut 4 and the screw shaft 2 by slidingly contacting the outer peripheral surface of the screw shaft 2 and the surface of the screw groove 2a. A grease supply port 8 is provided in the flange portion 4 b of the nut 4.
　ボールねじ装置１は、いわゆるコマ循環式のボールねじ装置である。ナット４には、転動したボール３を転動路の所定の地点まで送り戻すための循環部品として複数のコマ７が備えられている。このコマ７は、ナット４に径方向へ貫通した取り付け孔５に嵌め込まれている。コマ７は、Ｆｅ－２Ｎｉ－ＣやＦｅ－８Ｎｉ等の金属材料を用いた焼結品や樹脂材料から形成することができる。 The ball screw device 1 is a so-called top circulation type ball screw device. The nut 4 is provided with a plurality of tops 7 as circulating parts for sending the rolled ball 3 back to a predetermined point on the rolling path. The top 7 is fitted in an attachment hole 5 that penetrates the nut 4 in the radial direction. The top 7 can be formed from a sintered product or a resin material using a metal material such as Fe-2Ni—C or Fe-8Ni.
　上記構成により、ボールねじ装置１は、ねじ軸２を回転させることで、複数のボール３が転動路内を転動し、ナット４を軸方向へ移動させることができる。上記転動路を転動する複数のボール３は、ねじ軸２の周りを約一周すると、コマ７によって再度転動路の元の位置に戻されるという循環をするように構成されている。 With the above configuration, the ball screw device 1 can rotate the screw shaft 2 to cause the plurality of balls 3 to roll in the rolling path and move the nut 4 in the axial direction. The plurality of balls 3 rolling on the rolling path are configured to circulate such that when they make a round around the screw shaft 2, they are returned to the original position of the rolling path again by the top 7.
　このようなボールねじ装置１においては、上述したように、製造後に防錆油を塗布することにより、簡単な処理で錆の発生を抑えることができ、ボールねじ装置１の保管・管理を簡易にすることができる。しかしながら、顧客先で防錆油を除去する処理が煩雑となっていた。そこで、本願発明者は、以下のように、顧客が包装を開封すると、すぐにボールねじ装置１を設置して使用することを可能とする包装済み直動装置及び直動装置の包装方法を発明した。 In such a ball screw device 1, as described above, by applying rust preventive oil after manufacturing, the occurrence of rust can be suppressed by simple processing, and the storage and management of the ball screw device 1 can be simplified. can do. However, the process of removing the rust preventive oil at the customer site has been complicated. Therefore, the inventor of the present invention invented a packaged linear motion device and a packaging method for the linear motion device that enables the ball screw device 1 to be installed and used as soon as the customer opens the package as follows. did.
　図２に示すように、本発明の包装済み直動装置１００は、ボールねじ装置１を二重包装している。第２包装体としての内側フィルム袋１１は、ボールねじ装置１全体を覆い包む筒状本体部と共に、一方の端部に開口部１１ａを有している。 As shown in FIG. 2, the packaged linear motion device 100 of the present invention double-wraps the ball screw device 1. The inner film bag 11 as the second package has an opening 11a at one end together with a cylindrical main body that covers and encloses the entire ball screw device 1.
　第１包装体としての外側フィルム袋１２は、内側フィルム袋１１で覆い包まれたボールねじ装置１を収容し、ヒートシールやジッパーなどを用いて密封されており、内側フィルム袋１１の外側で開口部１１ａから離れた位置に乾燥剤１３を内包している。これにより、錆びの発生を長期にわたって防止することができる。また、内側フィルム袋１１と外側フィルム袋１２とによりボールねじ装置１を二重包装すると共に内側フィルム袋１１に開口部１１ａを設けているため、乾燥剤１３の効果を発揮させつつ、乾燥剤１３をボールねじ装置１に接触させないようにすることができる。乾燥剤の材料としては特に制限はなく、例えばシリカゲルが使用される。 The outer film bag 12 as the first package contains the ball screw device 1 covered with the inner film bag 11 and is sealed using a heat seal, a zipper or the like, and is opened outside the inner film bag 11. A desiccant 13 is included at a position away from the portion 11a. Thereby, generation | occurrence | production of rust can be prevented over a long period of time. In addition, since the ball screw device 1 is double-wrapped by the inner film bag 11 and the outer film bag 12 and the opening 11a is provided in the inner film bag 11, the desiccant 13 is exhibited while exhibiting the effect of the desiccant 13. Can be prevented from contacting the ball screw device 1. There is no restriction | limiting in particular as a material of a desiccant, For example, a silica gel is used.
　内側フィルム袋１１及び外側フィルム袋１２の材質としては、例えばポリエチレン樹脂やポリプロピレン樹脂、ポリエチレンテレフタレート樹脂などのプラスチック材料が好適に用いられる。 As the material of the inner film bag 11 and the outer film bag 12, plastic materials such as polyethylene resin, polypropylene resin, and polyethylene terephthalate resin are preferably used.
　また、内側フィルム袋１１及び外側フィルム袋１２として、紙や不織布の他、プラスチック材料に対してアルミニウムなどの金属などを蒸着若しくは貼り合わせなどして組み合わせた各種複合材料フィルムなども使用することができる。 Moreover, as the inner film bag 11 and the outer film bag 12, various composite material films in which a metal such as aluminum is vapor-deposited or bonded to a plastic material in addition to paper and non-woven fabric can be used. .
　運搬の際は、段ボールなどからなる外箱に包装済み直動装置１００を入れて運搬することができる。 During transportation, the packaged linear motion device 100 can be placed in an outer box made of cardboard or the like for transportation.
　ボールねじ装置１の包装方法としては、ボールねじ装置１を開口部１１ａから内側フィルム袋１１内に挿入し、内側フィルム袋１１の更に外側を外側フィルム袋１２で包み、乾燥剤１３を入れて密封する方法を用いることができる。 As a packaging method for the ball screw device 1, the ball screw device 1 is inserted into the inner film bag 11 through the opening 11a, the outer side of the inner film bag 11 is wrapped with the outer film bag 12, and the desiccant 13 is put in and sealed. Can be used.
　ボールねじ装置１は、使用前の静的環境下において、防錆用グリースがナット４とねじ軸２との間に充填されている。また、ナット４とねじ軸２の外表面には防錆グリース又は防錆油が塗布されている。これにより使用前の期間において、ねじ軸２と、ボール３と、ナット４に錆びが発生するのを更に防ぐことができる。ナット４とねじ軸２との間への防錆用グリースの充填は、ナット４のグリース供給口８から行う。防錆用グリースは、室温環境である２５℃において混和ちょう度範囲が３１０～３４０のちょう度番号１号のものを用いる。 The ball screw device 1 is filled with a rust preventive grease between the nut 4 and the screw shaft 2 in a static environment before use. Further, rust preventive grease or rust preventive oil is applied to the outer surfaces of the nut 4 and the screw shaft 2. As a result, it is possible to further prevent the screw shaft 2, the ball 3, and the nut 4 from being rusted before use. The antirust grease is filled between the nut 4 and the screw shaft 2 from the grease supply port 8 of the nut 4. As the rust-preventing grease, one having a consistency number of No. 1 having a miscibility range of 310 to 340 at 25 ° C., which is a room temperature environment, is used.
　ボールねじ装置１の使用に先立ち、外側フィルム１２と内側フィルム１１は取り外される。ボールねじ装置１の使用時においては、室温環境である２５℃において混和ちょう度範囲が４４５～４７５のちょう度番号０００号の潤滑用グリースを自動給油方式によりグリース供給口８から供給する。使用開始時において、防錆用グリースは、潤滑用グリースによって押され、ナット４両端のシール部材６とねじ軸２との間の僅かな隙間１０から徐々に排出されて、防錆用グリースが潤滑用グリースに入れ替わる。 Prior to the use of the ball screw device 1, the outer film 12 and the inner film 11 are removed. When the ball screw device 1 is used, lubricating grease having a consistency number 000 having a blending consistency range of 445 to 475 is supplied from the grease supply port 8 by an automatic lubrication system at 25 ° C. which is a room temperature environment. At the start of use, the rust-preventing grease is pushed by the lubricating grease, and is gradually discharged from the slight gap 10 between the seal member 6 at both ends of the nut 4 and the screw shaft 2, and the rust-preventing grease is lubricated. Replace with grease.
　このように、本発明では、防錆用グリースとして、室温環境である２５℃における混和ちょう度範囲が３１０～３４０の、軟らかいものを使用しているので、潤滑用グリースの自動給油によって自動的に押し出されることが可能となっている。一方で、防錆用グリースは潤滑用グリースよりもちょう度を低くしており、潤滑用グリースよりも硬く付着力が強いため、漏出しにくく、外気を遮断し、防錆効果を発揮することができる。 As described above, in the present invention, a soft rust preventive grease having a miscibility range of 310 to 340 at 25 ° C., which is a room temperature environment, is automatically used by automatic lubrication grease lubrication. It can be pushed out. On the other hand, the grease for rust prevention has a lower consistency than the grease for lubrication, and it is harder and stronger in adhesion than the grease for lubrication. it can.
　防錆用グリースの潤滑用グリースとの違いはちょう度のみで潤滑性に変わりはないので、防錆用グリースが若干ボールねじ装置１内に残っても問題ない。このため、防錆用グリースの洗浄作業をする必要がなくなり、ボールねじ装置１の設置作業時間が短縮化されるので、生産効率を向上させることができる。 The difference between the rust-preventing grease and the lubricating grease is only consistency and there is no change in lubricity, so there is no problem even if a little rust-preventing grease remains in the ball screw device 1. For this reason, it is not necessary to clean the rust preventive grease, and the installation work time of the ball screw device 1 is shortened, so that the production efficiency can be improved.
　上記シール部材６は、潤滑用グリースの自動給油によって防錆用グリースが自動的に押し出されることが可能な構成を有している。すなわち、ねじ軸２の外周面及びねじ溝２ａの面に対するシール部材６の内周面の圧接力が強いと、防錆用グリースが押し出されにくくなるし、圧接力が弱いとシール性が低下することになるので、この圧接力は適度に調整する。 The sealing member 6 has a configuration in which the rust preventive grease can be automatically pushed out by automatic lubrication grease. That is, if the pressure contact force of the outer peripheral surface of the screw shaft 2 and the inner peripheral surface of the seal member 6 with respect to the surface of the screw groove 2a is strong, the rust preventive grease is difficult to be pushed out, and if the pressure contact force is weak, the sealing performance is deteriorated. Therefore, this pressure contact force is adjusted appropriately.
　以上の包装済み直動装置、及び直動装置の包装方法によれば、装置設置前の防錆油の処理にかかる時間と労力を軽減することができる。 According to the above packaged linear motion device and the packaging method of the linear motion device, it is possible to reduce the time and labor required to process the rust preventive oil before the device is installed.
