【発明の詳細な説明】
〔産業上の利用分野〕
この発明は総ころ形式の軸受を対象機器に組み付ける前
のプレアセンブリないしは仮保持構造、および、その組
み付け方法に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a preassembly or temporary holding structure before assembling a full complement bearing to a target device, and a method for assembling the same.
減速機の遊星機構などのように高負荷が作用するところ
では、限られたスペースで高負荷容量を有する総ころ形
式の軸受が採用される。このため、総ころ軸受はできる
だけ大きな径のころをできるだけ多く保有できるように
、内・外輪を使用せず、ころを直接組み付けるようにし
たものが多い、そして、従来、軸受メーカーではころの
みを供給し、ユーザーにてそのころを１本づつ挿入して
組み付けるといった作業を行なっていた。In places where high loads are applied, such as in the planetary mechanism of a speed reducer, full roller type bearings are used, which have a high load capacity in a limited space. For this reason, in order to have as many large-diameter rollers as possible, full-roller bearings often do not use inner or outer rings, and the rollers are directly assembled.In the past, bearing manufacturers only supplied rollers. However, the user had to insert and assemble the rollers one by one.
〔発明が解決しようとする課題］
述べたような従来の組み付け方法では、ころが倒れたり
、こる欠品が生ずるなど、組み付け難と危険性がつきま
とう、また、ころがばらのままではころの取扱いも極め
て不便であるほか、ころの表面に疵がつきやすい。[Problems to be Solved by the Invention] With the conventional assembly method as described above, assembly is difficult and dangerous, such as rollers falling down, getting stuck or missing parts, and it is difficult to handle the rollers while they are still loose. In addition to being extremely inconvenient, the surface of the rollers is also prone to scratches.
そこで、この発明の主な目的は、総ころ軸受の取扱いや
、その組み付け作業を容易にすることである。Therefore, the main object of the present invention is to facilitate the handling and assembly of full roller bearings.
この発明の総ころ軸受は、環状に配列した所定数のころ
を、ころ列と内接する内筒と、ころ列と外接する外筒と
で、プレアセンブリ状態に仮保持させるようにした。In the full roller bearing of the present invention, a predetermined number of rollers arranged in an annular manner are temporarily held in a pre-assembled state by an inner cylinder inscribed with the roller row and an outer cylinder circumscribed with the roller row.
内筒および外筒は、いわばダミーの軸受内・外輪である
。したがって、鋼板プレス成形品、樹脂成形品など任意
の材料でつくることができる。なお、剛性補強、搬送時
等の取扱いを容易にするため、端部に鍔ないしフランジ
を設けてもよい、また、内・外輪ところとを組み合わせ
る際の作業性を考慮してころの安定を図るため、グリー
スを塗布してもよい。The inner cylinder and the outer cylinder are, so to speak, dummy inner and outer rings of the bearing. Therefore, it can be made of any material such as a steel plate press molded product or a resin molded product. In addition, a collar or flange may be provided at the end to strengthen the rigidity and facilitate handling during transportation, etc. Also, the rollers may be stabilized in consideration of workability when assembling the inner and outer rings. Therefore, you may apply grease.
この発明の総ころ軸受の組み付け方法は、上述のころと
内・外筒からなるプレアセンブリを、相手方部品の孔と

孔に押し込むと同時に外筒をころから分離させ、次に、
ころ列と内接する径の軸ないしはピンを押し込むと同時
に内筒を押し出すようにしたものである。The method for assembling the full roller bearing of this invention is to align the preassembly consisting of the rollers and inner and outer cylinders described above concentrically with the holes of the mating component, and push only the rollers and inner cylinder into a hole with a diameter that circumscribes the row of rollers. At the same time, the outer cylinder is separated from the rollers, and then
The inner cylinder is pushed out at the same time as the shaft or pin whose diameter is inscribed in the roller row is pushed in.

おける使用を想定していることから、組み付けを可能な
らしめるため、内＊（４）にはフランジを設けていない
が、そのような組み付け上の支障がない限り、内筒（４
）にも設けることができる（第４図参照）。In the embodiment shown in FIG. 1, two rows of rollers (2) are temporarily held by an inner cylinder (4) and an outer cylinder (6) with spacers (3) interposed therebetween. The outer cylinder (6) has an inward flange (61) at one end.
is formed. This flange (61) restricts the axial position of the roller (2), so when assembling the roller (2) and the inner and outer cylinders (4, 6) or when transporting,
It is possible to prevent the roller (2) from slipping out or falling off. Since this example is intended to be used in a shaft support structure as shown in Figure 3, a flange is not provided on the inner part (4) to enable assembly. As long as there is no problem with assembly, the inner cylinder (4
) can also be provided (see Figure 4).

て後に残される。To assemble it into the target device, first, as shown in Fig. 2, align the preassembly concentrically with the hole (81) of the mating part (in this case, the planetary gear) (8), and then insert a cylindrical or cylindrical jig. (10) is commonly applied to the end faces of the pusher (2) and the inner cylinder (4), and the both are pushed in the axial direction toward the hole (81). Then, since the outer cylinder (4) abuts against the end face of the planetary gear (8) and is prevented from moving, it slides relative to the rollers (2). Then, the hole (2) is the hole (8
When it has fully entered the tube (4), only the outer cylinder (4) will be separated and left behind.
この状態では、ころ列が遊星歯車（８）の孔（８１）に
内接した状態で内筒（４）により円環状に保持されてい
る。In this state, the roller row is held in an annular shape by the inner cylinder (4) in a state inscribed in the hole (81) of the planetary gear (8).

8) is placed at a predetermined position on the carrier (14) with side plates (12) interposed on both sides, as shown in FIG. Then, the pin (16) is inserted through one hole of the carrier (14). Then, this pin (16) touches the inner cylinder (4) at the tip.
) while pushing out, and when the front part has fully entered,
It completely replaces the inner cylinder (4). This allows the planetary gear (
8) is connected to the pin (1) of the carrier (14) via a full roller bearing.

手間および工数ははるかに軽減される。Although the explanation has been given using a planetary gear as an example, the present invention can be applied to bearings of ordinary gears and other rotating parts. However, especially in the case of a planetary gear mechanism, the planetary gear (8) must be held within the frame of the carrier (14) together with the side plate (12) and the pin (16) must be inserted, so the conventional rollers must be inserted. Compared to the method of inserting books one by one, the effort and man-hours are far reduced.
ころ列は２列に限らず、−列（第４図）または３列以上
であってもよく、この発明の効果は、ころ数またはころ
列が多ければ多いほど顕著なものとなる。The number of rows of rollers is not limited to two, but may be - rows (FIG. 4) or three or more rows, and the effects of the present invention become more pronounced as the number of rollers or roller rows increases.
また、第４図に示すように、保持器（１８）を使用する

期の効果を得ることができる。Further, as shown in FIG. 4, even if a cage (18) is used, if the cage (18) is not equipped with a means to prevent the cage (18) from falling off (2"), the present invention is not applicable. The desired effect can be obtained by applying it and temporarily holding it with the inner and outer cylinders (4', 6'').

扱いや管理が容易となるばかりでなく、保管や搬送中に
ころに疵をつける心配がない。As explained above, this invention holds a predetermined number of rollers in a pre-assembled state using dummy inner and outer cylinders, which not only makes handling and management easier, but also eliminates the risk of scratches on the rollers during storage or transportation. There is no.
また、対象機器に組み付けるにあたっても、ころ数を確

なるころの倒れも確実に防止できる。In addition, when assembling it into the target equipment, you do not have to worry about checking the number of rollers, and you can load all the rollers at once and in alignment, instead of inserting and lining them up one by one as in the past. The work is much easier and the efficiency is significantly improved. Furthermore, there is no fear of missing items, and it is also possible to reliably prevent rollers from falling down, which causes skew.
