Description

【発明の詳細な説明】 〔技術分野〕 この発明は、摺動体としての樹脂円筒を金属円筒と一体
化してなるすべり軸受の製造法に関するものである。Description: TECHNICAL FIELD The present invention relates to a method for manufacturing a sliding bearing in which a resin cylinder as a sliding body is integrated with a metal cylinder.

〔従来技術〕 従来、樹脂を使用したすべり軸受としては、例えば、樹
脂単体の軸受，巻ブッシュ型軸受，金属性ブッシュに樹
脂を嵌入接着した軸受などがある。[Prior Art] Conventionally, as a sliding bearing using a resin, for example, there is a bearing of a resin alone, a wound bush type bearing, a bearing in which a resin is fitted and adhered to a metal bush.

まず、樹脂単体の軸受についてみれば、薄肉円筒状に形
成すると軸受強度が低下するので、現状としては、厚肉
円筒状のものが用いられているが、ハウジングに固定
後、温度変化によって内径の収縮が大となり、軸との間
の半径方向の隙間を50μｍ以下にすることができないの
で、回転精度が悪く、しかも初期摩耗が大きいという欠
点を有している。First, regarding the bearing made of resin alone, since the bearing strength decreases when formed into a thin-walled cylindrical shape, the thick-walled cylindrical shape is currently used. Since the shrinkage is large and the radial gap between the shaft and the shaft cannot be 50 μm or less, there are disadvantages that the rotation accuracy is poor and the initial wear is large.

次に、巻ブッシュ型軸受は、予め樹脂層をコーティング
した金属板、例えば鋼板を該樹脂層を内側にして円形に
巻いて形成したものであるが、シートを曲げて作るた
め、真円度が50μｍ程度しか得られず、更に隙間も50μ
ｍ以上を必要とするので、精度が悪いという難点があ
る。Next, the wound bush type bearing is formed by winding a metal plate coated with a resin layer in advance, for example, a steel plate in a circular shape with the resin layer on the inside. Only about 50 μm can be obtained, and the gap is 50 μm.
Since m or more is required, there is a drawback that the accuracy is poor.

次に、金属性ブッシュに樹脂を嵌入接着した軸受につい
ては、まず、製造方法に欠点があり、工数を多く要す
る。例えば、特にPTFE（テフロン）は接着剤が利かない
ので、接着部分のみに化学処理を施し、軸受面に接着剤
が入らないように接着しなければならず、手間がかか
る。また、他の樹脂の場合も接着そのものが面倒で量産
性に欠けるという問題がある。Next, as for the bearing in which the resin is fitted and adhered to the metallic bush, the manufacturing method has a defect and requires a lot of man-hours. For example, since PTFE (Teflon) is not suitable for adhesives, it is necessary to perform chemical treatment only on the bonded portion so as to prevent the adhesive from entering the bearing surface, which is troublesome. Further, in the case of using other resins, there is a problem that adhesion itself is troublesome and mass productivity is poor.

この他の欠点は、薄肉円筒を作るのがむずかしいという
ことである。例えば、PTFEは、機械加工，圧縮成形、あ
るいは押出成形が困難である。これは、被加工物に剛性
がなく、製品精度がよく出ないからである。Another drawback is that it is difficult to make a thin cylinder. For example, PTFE is difficult to machine, compression mold, or extrude. This is because the work piece has no rigidity and the product accuracy is not good.

〔発明の目的〕[Object of the Invention]

この発明は、上記の問題点に鑑みてなされたもので、金
属円筒の内周面に形成した凹凸面に樹脂円筒を密着噛合

造法を提供することを目的とする。The present invention has been made in view of the above problems, and has a highly precise and strong two-layer structure in which a resin cylinder is integrally brought into close contact with an uneven surface formed on the inner peripheral surface of the metal cylinder. An object of the present invention is to provide a method for manufacturing the sliding bearing, which can obtain the sliding bearing.

〔実施例〕〔Example〕

以下、この発明の実施例を第１図〜第３図によって説明
する。この実施例は、第５図に示すすべり軸受９の製造
法である。An embodiment of the present invention will be described below with reference to FIGS. This embodiment is a method of manufacturing the slide bearing 9 shown in FIG.

このすべり軸受９は、外層を構成する金属円筒２と、内

内周面側に樹脂円筒８を高圧射出成形し、これを金属円
筒２の内周面に形成した凹凸面に密着噛合させて、両者
2,8を一体に結合したものである。The slide bearing 9 is composed of a metal cylinder 2 forming an outer layer and a resin cylinder 8 forming an inner layer, and the resin cylinder 8 is high-pressure injection-molded on the inner peripheral surface side of the metal cylinder 2, and the metal cylinder 2 is formed. Closely mesh with the uneven surface formed on the inner peripheral surface of
It is a combination of 2,8.

この製造法は、射出成形できる種類の樹脂を対象として
のみ実施し得る方法で、その製造工程は次のとおりであ
る。This manufacturing method is a method that can be carried out only for resins that can be injection-molded, and the manufacturing process is as follows.

（１）金属円筒作成工程 第１図に示すように、金属引抜きパイプ１から突切りに
より金属円筒２を得る。(1) Metal Cylinder Making Step As shown in FIG. 1, a metal cylinder 2 is obtained by cutting off the metal drawing pipe 1.

（２）凹凸面形成工程 第２図に示すように、金属円筒２の内面にローレット３
による転造、ブローチ（機械加工）などにより凹凸の刻
み目４を形成する。(2) Concavo-convex surface forming step As shown in FIG. 2, the knurl 3 is formed on the inner surface of the metal cylinder 2.
The uneven notch 4 is formed by rolling or broaching (machining).

（３）金属円筒設定工程 第３図に示すように、刻み目４を形成した金属円筒２

てインサート設定する。(3) Metal Cylinder Setting Step As shown in FIG. 3, the metal cylinder 2 having the notch 4 is formed.
Is a space necessary for the metal cylinder 2 to be elastically or plastically deformed by receiving the injection inner pressure of the resin between the inner peripheral surface of the frame mold 5a of the injection molding mold 5 and the outer peripheral surface of the metal cylinder 2. S is set and insert setting is performed.

（４）高圧射出成形工程 第４図に示すように、例えば、1,000kg/cm2以上の金型
内圧をかけて高圧インサート成形を行う。このとき、金
属円筒２は、これと円柱状芯型5bと枠型5aとで形成され

となる。(4) High-pressure injection molding process As shown in FIG. 4, for example, high-pressure insert molding is performed by applying a mold internal pressure of 1,000 kg / cm 2 or more. At this time, the metal cylinder 2 is pushed and expanded by the pressure of the molten resin 7 pressed into the cavity 6 formed by this, the cylindrical core mold 5b and the frame mold 5a until it comes into pressure contact with the inner surface of the frame mold 5a. . Then, the resin 7 press-fitted into the cavity 6 is in a state where internal stress is generated, and the resin 7 is solidified in the state as it is.
Becomes

金属円筒２が樹脂円筒８の収縮量よりも多く弾性回復す
れば、金属円筒２の凹凸の刻み目４と樹脂円筒８との外
周面との間に隙間は発生せず、また、回復量が更に大き
い場合には、樹脂円筒８は金属円筒２によって締め付け
られた状態となる。しかも、高圧で射出成形されている
ため樹脂円筒８の収縮は可及的に小さくなるので、締め
付けの度合は更に大きくなる。If the metal cylinder 2 elastically recovers more than the contraction amount of the resin cylinder 8, no gap is generated between the concave and convex notches 4 of the metal cylinder 2 and the outer peripheral surface of the resin cylinder 8, and the recovery amount is further increased. When it is large, the resin cylinder 8 is in a state of being clamped by the metal cylinder 2. Moreover, since the resin cylinder 8 is injection-molded at a high pressure, the shrinkage of the resin cylinder 8 is as small as possible, so that the degree of tightening is further increased.

このようにして、金属円筒２と樹脂円筒８は、完全に一
体化した仕上品（すべり軸受）９となる。In this way, the metal cylinder 2 and the resin cylinder 8 become a completely integrated finished product (slide bearing) 9.

（５）製品仕上げ工程 必要精度によっては、仕上品９の外径，内径，端面を機
械加工して製品とする。(5) Product finishing process Depending on the required accuracy, the outer diameter, inner diameter, and end surface of the finished product 9 are machined into a product.

得られた仕上品９は、金属円筒２と樹脂円筒８が金属円
筒２に予圧をかけた状態で一体化されているため、樹脂
円筒８の分子密度が高くなり、その耐摩耗性が向上する
のみならず、低温使用時においても、金属円筒２と樹脂
円筒８との間に隙間は生じない。In the obtained finished product 9, the metal cylinder 2 and the resin cylinder 8 are integrated in a state where the metal cylinder 2 is preloaded, so that the resin cylinder 8 has a high molecular density and its abrasion resistance is improved. In addition, no gap is formed between the metal cylinder 2 and the resin cylinder 8 even when used at low temperature.

上記製造方法によれば、通常成形程度の型内圧の成形
（約1,000kg/cm2）でもガタなしの密着成形ができた。
これは、アルミ円筒の外径とキャビティ内径との間に適
当な隙間を設け、内圧でアルミ円筒を拡張してその弾性
力でガタをなくすることができたためと思われる。According to the above-mentioned manufacturing method, contact molding without rattling could be achieved even with molding at a mold pressure of about normal molding (about 1,000 kg / cm 2 ).
This is probably because an appropriate gap was provided between the outer diameter of the aluminum cylinder and the inner diameter of the cavity, the aluminum cylinder was expanded by the internal pressure, and the elastic force eliminated the backlash.

さらに、アルミ円筒が弾性変形を越えて塑性変形するま
で隙間を広げたところ、非常に優れた効果が得られた。
すなわち、成形後のアルミ円筒の外径の真円度，円筒
度，寸法精度が著しく向上した。Furthermore, when the gap was widened until the aluminum cylinder exceeded the elastic deformation and plastically deformed, a very excellent effect was obtained.
In other words, the roundness, cylindricity, and dimensional accuracy of the outer diameter of the aluminum cylinder after molding were significantly improved.

また、成形前、数10μｍのだ円で、外径にバラツキのあ
ったアルミ円筒の外径が、成形後は真円度が４μm,外径
が８μｍのバラツキ，円筒度が４μｍの範囲に入った。
これは、樹脂の内圧によりアルミ円筒を金型に倣わせて
矯正することができたからであり、アルミ円筒の精度向
上には、塑性域まで変形されることが大きく寄与してい
るものと思われる。In addition, before molding, the outer diameter of an aluminum cylinder with an ellipse of several tens of μm and the outer diameter varied, but after molding, the roundness was 4 μm, the outer diameter was 8 μm, and the cylindricity was in the range of 4 μm. It was
This is because it was possible to correct the aluminum cylinder by following the mold by the internal pressure of the resin, and it seems that the deformation to the plastic region greatly contributes to the accuracy improvement of the aluminum cylinder. .

一方、樹脂側の内径精度も著しく向上する。通常成形で
は、真円度，内径寸法精度とも10μｍ内外が限度である
が、この実施例のような成形では、樹脂の固化過程にお
いて、ゲートが固化して成形機により加えられる保圧が

基づく圧力が数100kg/cm2の大きさで金型内部の樹脂に
かかるので、寸法精度のよいもの、すなわち、内径バラ
ツキ８μｍ、真円度５μｍという精度のものを量産的に
得ることができる。On the other hand, the precision of the inner diameter on the resin side is also significantly improved. In normal molding, both the roundness and the inner diameter dimensional accuracy are limited to within 10 μm, but in the molding as in this embodiment, in the resin solidification process, the gate is solidified and the holding pressure applied by the molding machine is Even if it does not reach the inside, the pressure due to elastic contraction of the aluminum cylinder is applied to the resin inside the mold with a size of several hundred kg / cm 2 , so it has good dimensional accuracy, that is, inner diameter variation 8 μm, roundness 5 μm It is possible to mass-produce products with such an accuracy.

このように、実施例のインサートモールドによれば、最
終機械仕上げを要せず、極めて高精度のすべり軸受を得
ることができる。また、樹脂円筒の内径と金属円筒の外
径との同軸度も数μｍ内外の精度が得られる。As described above, according to the insert mold of the embodiment, it is possible to obtain a slide bearing with extremely high accuracy without requiring final mechanical finishing. In addition, the coaxiality between the inner diameter of the resin cylinder and the outer diameter of the metal cylinder can be accurate to within a few μm.

表１は、実施例のすべり軸受の寸法精度を通常の樹脂円
筒のそれと比較したものである。Table 1 compares the dimensional accuracy of the sliding bearing of the embodiment with that of a normal resin cylinder.

なお、上記実施例においては、すべり軸受の内面は平滑
面であるが、動圧溝を成形時に同時に形成することもで
きる。スパイラルグループで動圧溝を形成した例では、
グリース潤滑により摩耗を極端に小さくすることができ
る。 In the above embodiment, the inner surface of the slide bearing is a smooth surface, but the dynamic pressure groove can be formed at the same time when molding. In the example where the dynamic pressure groove is formed by the spiral group,
Wear can be extremely reduced by grease lubrication.

〔発明の効果〕〔The invention's effect〕

以上説明してきたように、この発明によれば、金属円筒
の凹凸面側に樹脂円筒を高圧射出成形して密着一体化さ
せるようにしたので、次の効果を得ることができる。As described above, according to the present invention, the resin cylinder is high-pressure injection-molded on the concave-convex surface side of the metal cylinder so as to be closely adhered to each other, so that the following effects can be obtained.

（１）金属円筒と樹脂円筒との密着力が向上する。すな

応力により凹凸面において噛合しており、ガタは生じな
い。このため、この部分の摩耗や破損がなく、すべり軸
受の寿命が、後述の耐摩耗性の高いことと相俟って、著
しく長くなる。(1) The adhesion between the metal cylinder and the resin cylinder is improved. That is, the two cylinders mesh with each other on the uneven surface due to the internal stress of the metal cylinder without using an adhesive agent, and there is no backlash. Therefore, there is no wear or damage to this portion, and the life of the plain bearing is significantly lengthened in combination with the high wear resistance described later.

（２）樹脂円筒の肉厚を薄く形成することができる。外

間の小さいことから初期摩耗が少なく摩耗特性が向上す
る。また、熱膨張による寸法変化も小さいので、内径変
化が少なく、軸の食い付きを防止できる。(2) The resin cylinder can be made thin. This is because there is a metal cylinder in the outer layer and the resin cylinder and the resin cylinder are in close contact with each other so that the bearing strength does not decrease even if the resin is thin. Therefore, the dimensional accuracy of the inner diameter of the bearing can be increased, and the gap between the bearing and the shaft is 10 μm in radius.
It is possible to pack within. It is possible to secure extremely high dimensional accuracy as compared with the conventional resin-only bearing, which generally cannot be made smaller than about 50 μm. Therefore, since the gap is small, the initial wear is small and the wear characteristics are improved. In addition, since the dimensional change due to thermal expansion is small, the change in the inner diameter is small and the biting of the shaft can be prevented.

（３）外層に熱伝導のよいアルミや真鍮を用いることに
より、摺動部分からの熱放散と耐摩耗性に優れたすべり
軸受を得ることができる。(3) By using aluminum or brass having good heat conductivity for the outer layer, it is possible to obtain a slide bearing having excellent heat dissipation from the sliding portion and wear resistance.

軸受に好適である。(4) Conventional resin bearings and wound bush type bearings play back and cannot be used in place of oil-impregnated sintered alloy bearings or ball bearings, but the bearings obtained according to the present invention do not cause rattling with high precision. It can be used from that. In particular, it is suitable for a bearing with a dynamic pressure groove made of plastic, which requires precision in the clearance with the shaft.
