Abstract

押出し成形、圧縮成形、又は遠心加工によって合成樹脂製管を形成し、且つこのようにして製造された管又はそこから切断されたリングを好適には金属製のボス又はコア上に固定することにより、残留応力を殆ど有さない複合ウォームギアが提供される。本方法によれば、高性能高分子量熱可塑性樹脂が利用される。  By forming a synthetic resin tube by extrusion, compression molding or centrifugal processing, and fixing the tube thus produced or a ring cut therefrom, preferably on a metal boss or core A composite worm gear with little residual stress is provided. According to this method, a high performance high molecular weight thermoplastic resin is utilized.

Description

本発明は、合成材料、特に熱可塑性材料のギアリムを使用する可塑性ハイブリッドウォームギア及びギア半加工品の製造方法に関する。   The present invention relates to a method for producing plastic hybrid worm gears and gear blanks using gear rims of synthetic materials, in particular thermoplastic materials.

電子パワーステアリングシステム（ＥＰＳ）では、多様なウォーム／ウォームギア組が使用される。騒音の低減、より低い摩擦係数、及び磨耗低減の理由で、構成要素の一個又はその構成要素のギア部、好適にはウォームギアは通常、合成熱可塑性材料から構成される。   In electronic power steering systems (EPS), various worm / worm gear sets are used. For reasons of noise reduction, lower coefficient of friction, and wear reduction, one of the components or the gear portion of the component, preferably the worm gear, is usually composed of a synthetic thermoplastic material.

現在では、ウォームギア組を製造するために、２つの技術が使用されている。このようなウォームギアはＰＡ６又はＰＡ６／ＰＡ１２混合物のキャストされたナイロンリングから構成されており、ナイロンリングは略金属製のハブ（金属ボス）上に押圧或いはキャストされた後に、誘導加熱によって合わせて融着される。   Currently, two techniques are used to produce worm gear sets. Such a worm gear is composed of a cast nylon ring of PA6 or PA6 / PA12 mixture, and the nylon ring is pressed or cast on a substantially metal hub (metal boss) and then fused together by induction heating. Worn.

上記方法の欠点としては、ナイロンリングは約８０度までの温度でのみ有用なことが挙げられる。しかしながら、製品例えばウォームギアが自動車の乗車席又はより高温になり得る別の環境に使用されるならば、このような製品は使用されるべきではない。   A disadvantage of the above method is that nylon rings are useful only at temperatures up to about 80 degrees. However, if a product such as a worm gear is used in a car seat or another environment where it can get hotter, such a product should not be used.

ポリアミド（ＰＡ）６，６．６，４．６，１２，ＰＰＡ又はそれらの混合物に概ね基づく充填又は非充填合成材料を射出成形することにより、別の種類のウォームギアが製造される。また、ポリフェニレンサルファイド（ＰＰＳ）、ポリアミド−イミド（ＰＡＩ）、及びポリエーテルエーテルケトン（ＰＥＥＫ）は、直接的に（オーバモールドによって）ハブ通常は金属構造体を有するものに固定される。いずれの場合でも、製品への応力を低減させ、及び／、又は最終製品の所要寸法安定性を得るために、１以上の熱処理が必要とされる。   Another type of worm gear is produced by injection molding filled or unfilled synthetic materials generally based on polyamide (PA) 6,6.6, 4.6, 12, PPA or mixtures thereof. Also, polyphenylene sulfide (PPS), polyamide-imide (PAI), and polyetheretherketone (PEEK) are fixed directly (by overmolding) to the hub, usually with a metal structure. In any case, one or more heat treatments are required to reduce stress on the product and / or to obtain the required dimensional stability of the final product.

上記方法の欠点としては、射出成形工程は、上述したような用途によって必要とされる範囲の応力耐性を有していない製品、即ちウォームギアを導くことが挙げられる。
多くのこれら方法及び製品は従来技術、例えば「金属製ボスを有する樹脂成形物及びその製造方法」である特許文献１、「金属製ボスを有する樹脂成形物の製造方法」である特許文献２、「金属製ボスの熱可塑性樹脂成形物への固定方法」である特許文献３、及び「金属製ボスを有する樹脂成形物及びその製造方法」である特許文献４に記載されている。 A disadvantage of the above method is that the injection molding process leads to a product that does not have the stress resistance in the range required by the application as described above, ie a worm gear.
Many of these methods and products are conventional techniques, for example, Patent Document 1 which is “a resin molded product having a metal boss and a manufacturing method thereof”, Patent Document 2 which is “a method of manufacturing a resin molded product having a metal boss”, It is described in Patent Document 3 which is “a method of fixing a metal boss to a thermoplastic resin molded product” and Patent Document 4 which is “a resin molded product having a metal boss and a manufacturing method thereof”.

特許文献５は、熱可塑性樹脂の金属製コアへの成形方法によるウォームギアの製造を開示する。しかしながらこの方法は、従来技術の欠点全てを含んでいる。同様の開示は特許文献６に含まれる。先に開示した方法の不具合を共有しないウォームギアの製造方法を提供することが望まれる。

However, this method contains all the disadvantages of the prior art. Similar disclosure is included in US Pat. It would be desirable to provide a method of manufacturing a worm gear that does not share the deficiencies of the previously disclosed methods.

本発明は上記した懸案を鑑みてなされたものである。   The present invention has been made in view of the above-mentioned concerns.

本発明の目的の更なる詳細、特徴及び効果は、関連図面の説明から得られ、例えば本発明に係る２つの方法が説明される。
本発明方法によって製造される製品の一用途は、ＥＰＳシステム用ウォームギアに属する。このウォームギアは、自動車産業界では「***品」として評価される。従って、ＥＰＳシステムの製造業者は、使用中の破損を回避するのを助けるために、内部応力がない材料及び製品を必要とする。ここに説明する熱可塑性材料からの管の製造方法（押出し成形、圧縮成形及び遠心加工）全ては、製品に非常に低い応力レベルを提供し、それ故、自動車産業界の上記の必要性を満たす。特に射出成形品と比較して、本発明方法はより高い安全性レベルを提供することにより、著しい効果を呈する。 Further details, features and advantages of the object of the invention can be taken from the description of the associated drawings, for example two methods according to the invention are described.
One application of the product produced by the method of the invention belongs to the worm gear for EPS systems. This worm gear is evaluated as a “safety part” in the automobile industry. Thus, EPS system manufacturers need materials and products that are free of internal stresses to help avoid breakage during use. All of the methods for producing tubes from thermoplastic materials described here (extrusion, compression molding and centrifugal processing) provide very low stress levels to the product and therefore meet the above needs of the automotive industry. . In particular, compared to injection molded articles, the method of the present invention provides a significant effect by providing a higher level of safety.

自動車産業界では、ＥＰＳシステムを「フード（ボンネット）の下」のエンジン近くに置く傾向がある。従って、ＥＰＳシステムの全ての構成要素は高温、典型的には１２０度以上にさらされる。その結果、標準的なポリアミドはその物理的及び熱特性に起因して、このような用途では利用できない。同様な理由で、ポリアミド６から形成される管のキャスティングもまた、選択の対象とはならず、耐熱熱可塑性材料の射出成形品が唯一の代替物となる。本発明は、射出成形と比較して応力レベルがより低いという顕著な効果を伴う別の選択肢を提供する。これには、より明確な技術要件に対応するために、多様な耐熱材料から選択する可能性が含まれる。   In the automotive industry, there is a tendency to place EPS systems near the engine “under the hood”. Thus, all components of the EPS system are exposed to high temperatures, typically over 120 degrees. As a result, standard polyamides cannot be used in such applications due to their physical and thermal properties. For similar reasons, the casting of tubes formed from polyamide 6 is also not an option and the only alternative is an injection-molded part of a heat-resistant thermoplastic material. The present invention provides another option with the significant effect of lower stress levels compared to injection molding. This includes the possibility to choose from a variety of refractory materials to meet clearer technical requirements.

本発明の別の革新的態様としては、プロセスパラメータを調整することにより、熱可塑性樹脂製管の特性に直接影響を与え得ることが挙げられる。特に、高い分子量の樹脂を使用することにより、より一層の靭性が得られる。このような樹脂は、より高い溶融温度及び溶融粘度に起因して、射出成形方法では不可能であることが多い。   Another innovative aspect of the present invention is that the process parameters can be adjusted to directly affect the properties of the thermoplastic tube. In particular, even higher toughness can be obtained by using a high molecular weight resin. Such resins are often not possible with injection molding methods due to higher melt temperatures and melt viscosities.

本発明に係る第１実施形態について、図１によって更に詳細に説明する。
本発明のウォーム／ウォームギアの製造方法は、管１０１の所要寸法への押出し成形で始まる。これらの管から、適切な長さのリング１０２が切り離され（工程１１０）、必要であれば所定寸法に機械加工され、必要であれば溶剤によって洗浄され、且つハブ１０３上へ加圧される（工程１１１）。これらハブは好適には、機械加工、焼結、鍛造、及び／又は打ち抜き加工等の金属射出成形法によって形成される金属製ハブであるとともに、対応するリングに切断される。本発明の好適な実施形態によれば、リングをハブ上へ加圧する工程は、押出し成形の残留熱を使用することによって促進される。しかしながら代替実施形態によれば、工程１１１のために別の熱が使用されてもよい。リング１０２をハブ１０３上へ加圧した後に、装置は冷却される（工程１１２）。二次融着（工程１１３）によって、製品はハブ１０３に固定される。この二次融着は好適には、予備形成リング周りへの誘導コイル２００２によって予備形成される。使用される材料及び所望法に応じて、焼なまし工程（図１には図示なし）が使用されても良い。最終機械加工工程１１４では、製品が既に円板状になっていなければ複合円板となるように分離させられた後に、ギアに切断される。 The first embodiment according to the present invention will be described in more detail with reference to FIG.
The worm / worm gear manufacturing method of the present invention begins with the extrusion of tube 101 to the required dimensions. From these tubes, the appropriate length of ring 102 is cut (step 110), machined to the required dimensions if necessary, washed with solvent if necessary and pressurized onto hub 103 (step 110). Step 111). These hubs are preferably metal hubs formed by metal injection molding methods such as machining, sintering, forging, and / or stamping and are cut into corresponding rings. According to a preferred embodiment of the present invention, the process of pressing the ring onto the hub is facilitated by using the residual heat of extrusion. However, according to alternative embodiments, another heat may be used for step 111. After pressing the ring 102 onto the hub 103, the device is cooled (step 112). The product is fixed to the hub 103 by secondary fusion (step 113). This secondary fusion is preferably preformed by an induction coil 2002 around the preformed ring. Depending on the material used and the desired method, an annealing step (not shown in FIG. 1) may be used. In the final machining step 114, if the product is not already in the shape of a disc, it is separated into a composite disc and then cut into gears.

合成材料リングの内径が金属製ハブの外径よりも幾分小さいことが好ましい。
本実施形態に係る方法は、現在使用されている材料並びに上述したもの全てに使用され得る。付加的な効果は、半結晶／非結晶材料の場合にも生じる。低温で押出し成形すると共に、押出し成形後の迅速な冷却と組み合わせて押出し管の内面を重合体のＴｇ以下に維持することにより、内部の材料は非結晶（第１層）のままとなる。リングを切断すると共にＴｇより少し高い温度に予熱した後に、非結晶層はリングが管に簡単に且つ少ない応力増加を伴い加圧されるのを可能にする。融着の間に、材料は元の非結晶相の結晶化を可能にするまで加熱される。この方法の使用は、射出成形工程を経て作られた比較製品よりも大いに低い応力レベル及びより良好な磨耗特性を備えた製品へと至る。また、射出成形方法では、冷却の間における材料の収縮に起因するボイド形成の危険はよく知られた問題であるので、用途の安全性が増加する。しかしながら、ボイドの形成は押出し成形では完全に存在しない。 The inner diameter of the synthetic material ring is preferably somewhat smaller than the outer diameter of the metal hub.
The method according to this embodiment can be used for all currently used materials as well as those described above. Additional effects also occur with semi-crystalline / non-crystalline materials. By extruding at a low temperature and maintaining the inner surface of the extruded tube below the Tg of the polymer in combination with rapid cooling after extrusion, the internal material remains amorphous (first layer). After cutting the ring and preheating to a temperature slightly above Tg, the amorphous layer allows the ring to be easily pressed into the tube with a small increase in stress. During fusion, the material is heated until it allows crystallization of the original amorphous phase. Use of this method leads to products with much lower stress levels and better wear properties than comparative products made via an injection molding process. Also, in the injection molding method, the danger of void formation due to material shrinkage during cooling is a well-known problem, increasing the safety of the application. However, void formation is not completely present in extrusion.

ハブはいかなる適当な方法によって作られてもよく、また適度の長さのビレットのように、或いは連続的又は略連続的な製品のように、予め切られた長さで供給される。表面は好適には樹脂製外側部との堅固な適合を促進するように「凹凸が形成される」。サンドブラスト加工面、ねじ切り面或いは溝付き面の使用等、様々な種類の凹凸加工が利用され得る。刻み付き面、好適にはダイヤモンドパターンを備えたものが好適に使用される。   The hub may be made by any suitable method and is supplied in a pre-cut length, such as a moderately long billet, or a continuous or nearly continuous product. The surface is preferably “irregular” to promote a firm fit with the resin exterior. Various types of concavo-convex machining can be utilized, such as the use of sandblasted surfaces, threaded surfaces, or grooved surfaces. A knurled surface, preferably with a diamond pattern, is preferably used.

ハブは好適には、全部又は一部が金属製である。しかしながら、幾つかの用途では、非金属製ハブも有用である。一般的には、ハブの材料は、ギアとなるように切断され或いは機械加工される「外側」よりも高い強度特性を有する。適当な熱可塑性樹脂材料の例には、先に特定された重合体、並びにエポキシ樹脂、ビスマレイミド樹脂、ポリウレタン樹脂等の熱硬化性重合体があるが、但しこれらに限定されない。ハブ材料は一般的には、ハブのこれら夫々の部分の多様な要件に起因して、ギアアウタと異なる物理特性プロフィールを有すると共に、一般的により高い硬度及び耐熱性を有し、即ち熱可塑性樹脂がギア層よりも高い溶融温度を有する。強度要件の改善のために、このような非金属製ハブ材料は強化線維、例えばガラス、炭素、又はアラミド繊維等を含んでもよい。   The hub is preferably entirely or partially metal. However, for some applications, non-metallic hubs are also useful. In general, the hub material has higher strength properties than the “outside” that is cut or machined into a gear. Examples of suitable thermoplastic resin materials include, but are not limited to, the previously specified polymers and thermosetting polymers such as epoxy resins, bismaleimide resins, polyurethane resins and the like. The hub material generally has a different physical property profile than the gear outer due to the diverse requirements of these respective parts of the hub and generally has a higher hardness and heat resistance, i.e. It has a higher melting temperature than the gear layer. For improved strength requirements, such non-metallic hub materials may include reinforcing fibers such as glass, carbon, or aramid fibers.

熱可塑性又は熱硬化性ハブ材料はまた、誘導加熱が一層熱可塑性アウタをハブと融着させるために使用されるように、金属粒子を含む。同様に、金属管にハブ材料を充填させることにより、ハイブリッドハブが準備されてもよい。管は、ギアアウタへ加圧した後に、管及びアウタを共に溶解させるために容易に誘導加熱される。   The thermoplastic or thermoset hub material also includes metal particles such that induction heating is used to fuse the more thermoplastic outer to the hub. Similarly, a hybrid hub may be prepared by filling a metal tube with a hub material. After pressurizing the gear outer, the tube is easily induction heated to dissolve the tube and outer together.

図２に係る実施形態では、管１０１は連続的に又は半連続的に押出し成形され（工程１２０）、或いは予備成形コア１０５上へ遠心成形されることにより、中間製品１２１が得られる。融着１１３によって、先の実施形態に従い、予備形成製品周りへの誘導コイル２００によって、押出し成形された製品はコア１０５に固定される。最終機械加工工程１２２では、製品は切断及び打ち出し加工によって仕上げられる。   In the embodiment according to FIG. 2, the tube 101 is extruded continuously or semi-continuously (step 120) or is centrifugally formed on the preformed core 105 to obtain the intermediate product 121. By fusion 113, the extruded product is secured to core 105 by induction coil 200 around the preformed product according to the previous embodiment. In the final machining step 122, the product is finished by cutting and stamping.

本発明方法は、以下に説明される幾つかの代替方法を含む。
「ケーブル押出し成形」
本方法において、材料は予備形成されたコア上に連続的或いは半連続的に押出し成形される。コアはビレット状に（図１）、或いは「無端状」に（図２）形成される。 The method of the present invention includes several alternative methods described below.
