Description

本発明は、基材の表面に付着した樹脂フィルムからなる摺動層をもつ摺動部材およびその製造方法に関する。   The present invention relates to a sliding member having a sliding layer made of a resin film attached to the surface of a substrate, and a method for manufacturing the same.

鋼板などの基材の表面に樹脂製の摺動層を形成して、低摩擦性や耐焼付き性などを付与した摺動部材が、幅広い分野で用いられている。樹脂製の摺動層をもつ摺動部材を製造する方法としては、樹脂を塗料にして基材の表面へ塗装したり、溶融した樹脂を基材の表面で成形したり、などして摺動層を形成するのが一般的である。   A sliding member in which a resin sliding layer is formed on the surface of a base material such as a steel plate to provide low friction and seizure resistance is used in a wide range of fields. As a method of manufacturing a sliding member having a sliding layer made of resin, sliding is performed by coating the surface of the substrate with resin as a paint, or molding molten resin on the surface of the substrate. It is common to form layers.

たとえば、特許文献１には、樹脂ワニスに固体潤滑材や無機粒子を配合した塗料組成物を基材の表面に塗布後、硬化させて形成された摺動膜を有する摺動部材が開示されている。しかしながら、基材の曲面に塗料を用いて摺動膜を形成すると、摺動膜の表面にうねりやたれが生じ易い。そのため、摺動膜の形成後、摺動膜の表面に研磨等の加工が行われている。   For example, Patent Document 1 discloses a sliding member having a sliding film formed by applying a coating composition in which a solid lubricant or inorganic particles are blended in a resin varnish to a surface of a base material and then curing the coating composition. Yes. However, when the sliding film is formed on the curved surface of the base material using a paint, the surface of the sliding film is likely to swell and sag. For this reason, after the sliding film is formed, the surface of the sliding film is subjected to processing such as polishing.

一方、特許文献２のように、樹脂シートを熱圧着すれば、厚みや表面状態が均一な摺動層が形成できる。ところが、一般に樹脂シートは、シート状に成形する際にテンションをかけて作製されるため、熱圧着の際の加熱や加圧の条件に応じて、樹脂シートが変形する。特に、円柱形状の駆動軸の外周面に矩形の樹脂シートを一周させて熱圧着する場合には、摺動層の周方向に一致する樹脂シートの長さの変化が顕著である。たとえば、背向する２辺の長さが駆動軸の円周と同じ長さになるように樹脂シートを切り出しても、駆動軸の外周面に巻回して熱圧着する際に、樹脂シートが変形して長くなることで基材の外周に一周以上して重なり合いが生じたり、樹脂シートが収縮して短くなることで摺動性を低下させるような隙間ができたり、といった問題が生じる。すなわち、矩形の樹脂シートを周方向において寸法精度よく熱圧着することは、困難である。
特開２００４−３１６４９９号公報 特開２００６−０４５４９３号公報 On the other hand, as in Patent Document 2, if a resin sheet is thermocompression bonded, a sliding layer having a uniform thickness and surface state can be formed. However, since a resin sheet is generally produced by applying tension when it is formed into a sheet shape, the resin sheet is deformed according to the heating and pressurizing conditions during thermocompression bonding. In particular, when a rectangular resin sheet is made to make a round on the outer peripheral surface of a cylindrical drive shaft and thermocompression-bonded, the change in the length of the resin sheet corresponding to the circumferential direction of the sliding layer is significant. For example, even if the resin sheet is cut out so that the length of the two opposite sides is the same as the circumference of the drive shaft, the resin sheet is deformed when wound around the outer peripheral surface of the drive shaft and thermocompression bonded. As a result of the increase in length, the outer periphery of the base material is overlapped one or more times, and the resin sheet contracts and shortens, resulting in a gap that reduces sliding performance. That is, it is difficult to thermo-compress a rectangular resin sheet with high dimensional accuracy in the circumferential direction.

以下に、本発明の摺動部材の製造方法を実施するための最良の形態を図１〜図１４を用いて説明する。以下では、本発明の摺動部材の製造方法について説明するが、その内容は、適宜選択され、または組み合わされて、本発明の摺動部材にも適用可能である。   Below, the best form for implementing the manufacturing method of the sliding member of this invention is demonstrated using FIGS. Below, although the manufacturing method of the sliding member of this invention is demonstrated, the content is suitably selected or combined and it can apply also to the sliding member of this invention.

本発明の摺動部材の製造方法は、円形の断面をもつ基材と、該基材の外周面の少なくとも一部に熱圧着された樹脂シートで形成された摺動層と、を備える摺動部材を製造する方法である。   A manufacturing method of a sliding member according to the present invention includes a base material having a circular cross section, and a sliding layer formed of a resin layer thermocompression bonded to at least a part of the outer peripheral surface of the base material. It is a method of manufacturing a member.

基材は、その材質に特に限定はなく、金属製やセラミックス製の基材を用いることができる。金属製の基材であれば、たとえば、鉄や鋼などの鉄系材料、アルミニウムやＭｇ、Ｃｕ、Ｚｎ、Ｓｉ、Ｍｎ等を含むアルミニウム合金、銅やＺｎ、Ａｌ、Ｓｎ、Ｍｎ等を含む銅合金などが好ましい。また、セラミックス製の基材であれば、たとえば、アルミナ、ジルコニア、炭化珪素などが好ましい。   The material of the substrate is not particularly limited, and a metal or ceramic substrate can be used. If it is a metal substrate, for example, iron-based materials such as iron and steel, aluminum, aluminum alloys including Mg, Cu, Zn, Si, Mn, etc., copper, copper including Zn, Al, Sn, Mn, etc. Alloys are preferred. Moreover, if it is a ceramic base material, for example, alumina, zirconia, silicon carbide and the like are preferable.

基材の形状は、円形の断面を有すれば特に限定はない。たとえば、円柱形状や中空円筒形状が好ましく、断面形状も真円に限定されない。また、少なくとも樹脂シートが熱圧着される基材の外周面は、十点平均粗さ（ＪＩＳ）にして０．１〜１０μｍＲｚさらには１〜５μｍＲｚの表面粗さであるのが好ましく、０．１μｍＲｚ以上であれば、基材と樹脂シートとの密着性が向上し、１０μｍＲｚ以下であれば樹脂シートの表面（摺動面）への影響が小さくなるため好ましい。   The shape of the substrate is not particularly limited as long as it has a circular cross section. For example, a cylindrical shape or a hollow cylindrical shape is preferable, and the cross-sectional shape is not limited to a perfect circle. Further, at least the outer peripheral surface of the substrate to which the resin sheet is thermocompression bonded has a ten-point average roughness (JIS) of 0.1 to 10 μmRz, preferably 1 to 5 μmRz, and preferably 0.1 μmRz. If it is above, the adhesiveness between the substrate and the resin sheet is improved, and if it is 10 μmRz or less, the influence on the surface (sliding surface) of the resin sheet is reduced, which is preferable.

基材は、特に、圧縮機の摺動部品であるのが好ましい。すなわち、本発明の製造方法により得られる摺動部材は、圧縮機の摺動部材として好適である。具体的には、主として吸入室、吐出室およびシリンダボアをもつハウジングと、ハウジングに回転可能に支承された駆動軸と、駆動軸と同期回転可能な斜板と、斜板にシューを介して係留され斜板の傾斜角に応じてシリンダボア内を往復動して圧縮室を形成するピストンと、駆動軸と同期回転して圧縮室を吸入室と連通させる回転弁と、を備える圧縮機の駆動軸、ピストンまたは回転弁である。なお、回転弁であれば、圧縮室と吸入室とを連通させる連通口は、樹脂シートを熱圧着させて摺動層を形成した後に加工すればよい。   The substrate is particularly preferably a sliding part of a compressor. That is, the sliding member obtained by the manufacturing method of the present invention is suitable as a sliding member for a compressor. Specifically, a housing mainly having a suction chamber, a discharge chamber, and a cylinder bore, a drive shaft rotatably supported by the housing, a swash plate that can rotate in synchronization with the drive shaft, and a swash plate moored via a shoe. A drive shaft of a compressor comprising: a piston that reciprocates in a cylinder bore in accordance with an inclination angle of the swash plate; and a rotary valve that rotates in synchronization with the drive shaft to communicate the compression chamber with the suction chamber; Piston or rotary valve. In the case of a rotary valve, the communication port that connects the compression chamber and the suction chamber may be processed after the resin sheet is thermocompression bonded to form the sliding layer.

樹脂シートは、基材の外周面に熱圧着することができれば、その材質に特に限定はなく、求められる摺動特性に応じて選択すればよい。たとえば、樹脂シートは、少なくとも表層部にポリアリールケトン樹脂を含むとよい。ポリアリールケトン樹脂は、熱可塑性樹脂の中でも、高い機械的強度をもち、耐熱性、難燃性、耐摩耗性、耐薬品性、耐加水分解性などに優れている。そのため、少なくとも表層部にポリアリールケトン樹脂を含む樹脂シートを用いて構成され、その表層部を摺動面とした摺動層は、厳しい使用条件の下でも優れた摺動特性を示す。   The resin sheet is not particularly limited as long as it can be thermocompression bonded to the outer peripheral surface of the base material, and may be selected according to the required sliding characteristics. For example, the resin sheet may contain a polyaryl ketone resin at least in the surface layer portion. Polyaryl ketone resins have high mechanical strength among thermoplastic resins, and are excellent in heat resistance, flame retardancy, wear resistance, chemical resistance, hydrolysis resistance, and the like. Therefore, a sliding layer comprising at least a surface layer portion containing a polyaryl ketone resin and having the surface layer portion as a sliding surface exhibits excellent sliding characteristics even under severe use conditions.

ポリアリールケトン樹脂としては、ポリエーテルエーテルケトン（ＰＥＥＫ）樹脂やポリエーテルケトン樹脂などが挙げられる。ただし、ポリアリールケトン樹脂からなる樹脂シートを用いる場合には、ポリアリールケトン樹脂の融点が高く、溶融し難い。そのため、熱圧着しても劣化しない耐熱性の高い基材を用いる必要がある。互いに相溶性のよいポリアリールケトン樹脂と熱可塑性ポリイミド樹脂とを含む樹脂シートであれば、３００℃以下の低温であっても接着に適切な流動性を示す。また、樹脂シートは、低温の熱圧着であっても基材との密着性に優れる接着層と、この接着層に積層されポリアリールケトン樹脂を含む表面層と、からなる積層シートであってもよい。接着層としては、エポキシ樹脂等の熱硬化性樹脂を塗布した接着層、熱可塑性ポリイミド樹脂およびポリアリールケトン樹脂を含む接着層、などを用いることができる。熱可塑性ポリイミド樹脂としては、ポリエーテルイミド（ＰＥＩ）が好ましい。   Examples of the polyaryl ketone resin include polyether ether ketone (PEEK) resin and polyether ketone resin. However, when using a resin sheet made of a polyaryl ketone resin, the polyaryl ketone resin has a high melting point and is difficult to melt. Therefore, it is necessary to use a highly heat-resistant base material that does not deteriorate even when thermocompression bonded. If it is a resin sheet containing a polyaryl ketone resin and a thermoplastic polyimide resin that are compatible with each other, it exhibits fluidity suitable for adhesion even at a low temperature of 300 ° C. or lower. Further, the resin sheet may be a laminated sheet composed of an adhesive layer excellent in adhesion to the substrate even if it is low-temperature thermocompression bonding, and a surface layer laminated on the adhesive layer and containing a polyaryl ketone resin. Good. As the adhesive layer, an adhesive layer coated with a thermosetting resin such as an epoxy resin, an adhesive layer containing a thermoplastic polyimide resin and a polyaryl ketone resin, or the like can be used. As the thermoplastic polyimide resin, polyetherimide (PEI) is preferable.

樹脂シートは、さらに、固体潤滑剤を含んでもよい。固体潤滑剤を含む樹脂シートを用いれば、摺動層の摺動特性が向上する。固体潤滑剤としては、ポリテトラフルオロエチレン（ＰＴＦＥ）等のフッ素樹脂やフッ化黒鉛、フッ化カルシウムなどのフッ素化合物、二硫化モリブデン、二硫化タングステン等の硫化物、黒鉛やタルクなどの層状構造物、Ｐｂ、Ａｇ、Ｃｕ等の軟質金属やその化合物、など、固体潤滑剤として通常用いられているものであればよい。その他にも、酸化チタン、炭化タングステン、窒化ホウ素、メラミンシアヌレート等が使用できる。   The resin sheet may further contain a solid lubricant. If a resin sheet containing a solid lubricant is used, the sliding characteristics of the sliding layer are improved. Solid lubricants include fluorine resins such as polytetrafluoroethylene (PTFE), fluorine compounds such as graphite fluoride and calcium fluoride, sulfides such as molybdenum disulfide and tungsten disulfide, and layered structures such as graphite and talc. , Pb, Ag, Cu, and other soft metals and their compounds may be used as long as they are usually used as solid lubricants. In addition, titanium oxide, tungsten carbide, boron nitride, melamine cyanurate, etc. can be used.

特開２００６−４５４９３号公報（特許文献２）に開示されているフィルムは、本発明において樹脂シートとして好適に用いることができる。   The film disclosed in JP 2006-45493 A (Patent Document 2) can be suitably used as a resin sheet in the present invention.

樹脂フィルムの厚さに特に限定はないが、５〜１００μｍであるとよい。この範囲であれば、熱圧着により均一な摺動層を形成することができる。なお、樹脂フィルムの厚さは、摺動層の厚さとほぼ同等である。   Although there is no limitation in particular in the thickness of a resin film, it is good in it being 5-100 micrometers. Within this range, a uniform sliding layer can be formed by thermocompression bonding. Note that the thickness of the resin film is substantially equal to the thickness of the sliding layer.

本発明の摺動部材の製造方法では、樹脂シートを特定の形状にすることで、作業性を向上させた。本発明の摺動部材の製造方法では、樹脂シートを、平行四辺形のシート片とする。図１に平行四辺形のシート片の平面図およびこのシート片を基材に巻回する前の斜視図を示す。平行四辺形のシート片１０は、互いに平行な第一辺１１および第二辺１２と、互いに平行な第三辺１３および第四辺１４と、で区画される。第一辺１１および第二辺１２の長さＬは基材９の円周の長さＬ’（＝２πｒ）に略等しく、互いに平行な第一辺１１と第二辺１２との距離Ｗは摺動層の幅Ｗ’と略等しい。そして、第三辺１３および第四辺１４は、第一辺１１に垂直な方向（すなわち第二辺１２にも垂直な方向）に対して傾斜する。特に、図１に示す平行四辺形のシート片１０は、短い方の対角線１９と第一辺１１とが成す角θおよび対角線１９と第二辺１２とが成す角θが９０°以下である。ここで、摺動層の幅Ｗ’は、本発明の摺動部材の製造方法により得られる摺動部材において、基材の軸方向に延びる摺動層の幅とする。   In the manufacturing method of the sliding member of this invention, workability | operativity was improved by making a resin sheet into a specific shape. In the sliding member manufacturing method of the present invention, the resin sheet is a parallelogram sheet piece. FIG. 1 shows a plan view of a parallelogram sheet piece and a perspective view before the sheet piece is wound around a substrate. The parallelogram sheet piece 10 is partitioned by a first side 11 and a second side 12 that are parallel to each other, and a third side 13 and a fourth side 14 that are parallel to each other. The length L of the first side 11 and the second side 12 is substantially equal to the circumferential length L ′ (= 2πr) of the substrate 9, and the distance W between the first side 11 and the second side 12 parallel to each other is It is substantially equal to the width W ′ of the sliding layer. The third side 13 and the fourth side 14 are inclined with respect to a direction perpendicular to the first side 11 (that is, a direction perpendicular to the second side 12). In particular, in the parallelogram sheet piece 10 shown in FIG. 1, the angle θ formed by the shorter diagonal line 19 and the first side 11 and the angle θ formed by the diagonal line 19 and the second side 12 are 90 ° or less. Here, the width W ′ of the sliding layer is defined as the width of the sliding layer extending in the axial direction of the base material in the sliding member obtained by the manufacturing method of the sliding member of the present invention.

平行四辺形のシート片１０では、シート片１０の長さＬがＬ＝２πｒであれば、シート片１０の第一辺１１および第二辺１２に平行な方向（シート片１０の「長さ方向」と略記）と巻回方向（基材９に巻回するのであれば基材９の周方向）とを一致させて一周巻回すると、第一辺１１および第二辺１２はそれぞれ同一円周上で一致し、第三辺１３および第四辺１４は同一の線上で互いに当接する状態で一致する。ところが、シート片１０の長さ方向と巻回方向とに角度φをもたせて、第三辺１３と第四辺１４とが互いに当接する状態に一周巻回すると、巻回径は拡径される。そのため、同様にして基材９に巻回すると、図２の側面図に示すように、第三辺１３側の端部と第四辺１４側の端部とが重なり合う。また、シート片１０の長さ方向と巻回方向とに角度−φをもたせて、第三辺１３と第四辺１４とが互いに当接する状態に一周巻回すると、巻回径は縮径される。そのため、同様にして基材９に巻回すると、図３に示すように、対向する第三辺１３と第四辺１４との間に隙間が生じる。したがって、基材の周方向に一致する方向のシート片１０の寸法は、巻回方向の微調節により寸法の調整がされやすい。   In the parallelogram sheet piece 10, if the length L of the sheet piece 10 is L = 2πr, the direction parallel to the first side 11 and the second side 12 of the sheet piece 10 (the “length direction of the sheet piece 10”). ”) And the winding direction (the circumferential direction of the base material 9 if it is wound around the base material 9) are made to coincide with each other, and the first side 11 and the second side 12 are each set to the same circumference. The third side 13 and the fourth side 14 coincide with each other on the same line. However, when the sheet piece 10 is wound around in a state where the third side 13 and the fourth side 14 are in contact with each other with an angle φ between the length direction and the winding direction of the sheet piece 10, the winding diameter is expanded. . Therefore, when wound around the base material 9 in the same manner, the end on the third side 13 side and the end on the fourth side 14 side overlap as shown in the side view of FIG. Further, when the sheet piece 10 is wound once in a state where the third side 13 and the fourth side 14 are in contact with each other with an angle −φ in the length direction and the winding direction of the sheet piece 10, the winding diameter is reduced. The Therefore, when the substrate 9 is wound in the same manner, a gap is generated between the third side 13 and the fourth side 14 facing each other as shown in FIG. Therefore, the dimension of the sheet piece 10 in the direction coinciding with the circumferential direction of the substrate is easily adjusted by fine adjustment in the winding direction.

そこで、本発明の摺動部材の製造方法では、シート片１０の第一辺１１および第二辺１２と平行な方向（シート片１０の長さ方向）と基材９の略周方向とを一致させる。シート片１０の長さ方向と基材９の略周方向とを一致させるには、基材９の周方向に対するシート片１０の長さ方向に所定の角度をもたせることで、シート片１０を基材９に巻回する方向が微調整されればよい。このとき、シート片１０の長さ方向は、基材９の周方向に対して僅かに角度をもった状態、場合によっては、両方向が一致した状態となるのが好ましい。シート片１０は、平行四辺形であるため、巻回方向に所定の角度をもたせてシート片１０を基材９に略一周巻回することにより、加熱や加圧によりシート片１０の寸法に変化が生じても、第三辺１３と第四辺１４とを当接または所定の間隔で対向させることができる。なお、シート片１０の巻回方向は、熱圧着の際の加熱や加圧の条件に応じたシート片１０の変形量を予め見込んで、微調整されるとよい。   Therefore, in the manufacturing method of the sliding member of the present invention, the direction parallel to the first side 11 and the second side 12 of the sheet piece 10 (the length direction of the sheet piece 10) matches the substantially circumferential direction of the base material 9. Let In order to make the length direction of the sheet piece 10 and the substantially circumferential direction of the base material 9 coincide with each other, the sheet piece 10 is made to have a predetermined angle in the length direction of the sheet piece 10 with respect to the circumferential direction of the base material 9. The direction of winding around the material 9 may be finely adjusted. At this time, it is preferable that the length direction of the sheet piece 10 is slightly inclined with respect to the circumferential direction of the base material 9, and in some cases, both directions coincide with each other. Since the sheet piece 10 is a parallelogram, the sheet piece 10 is wound around the base material 9 with a predetermined angle in the winding direction, so that the size of the sheet piece 10 is changed by heating or pressurization. Even if this occurs, the third side 13 and the fourth side 14 can be brought into contact with each other or opposed to each other at a predetermined interval. Note that the winding direction of the sheet piece 10 may be finely adjusted in advance by considering the amount of deformation of the sheet piece 10 according to the heating and pressurizing conditions during thermocompression bonding.

また、本発明の摺動部材の製造方法では、シート片１０は、その第一辺１１および第二辺１２と平行な方向（シート片１０の長さ方向）と基材９の周方向とを一致させてから、第三辺１３側より、基材９に略一周巻回されてもよい。このとき、第三辺１３と第四辺１４とを所定の位置で対向させる。シート片１０は、平行四辺形であるため、シート片１０の長さ方向を基材９の周方向に対して僅かに角度をもたせた状態とする（すなわち巻回方向を微調整する）ことで、基材の周方向に一致するシート片１０の寸法を調整し易い。具体的には、基材９および／またはシート片１０を加熱して、シート片１０の第三辺１３側からシート片１０を基材９に巻回して熱圧着する際、シート片１０が収縮して長さＬが基材９の周方向の長さＬ’より短くなった場合、既に基材の外周面に熱圧着された第三辺１３の位置に合わせて、順次熱圧着される第四辺１４側の巻回方向を微調整することで、図４に示すように第三辺１３と第四辺１４とを同一の線上で一致させてシート片１０を隙間無く当接させたり、図５に示すように第三辺１３と第四辺１４との間に所定の幅の間隙１５をもって互いに対向させたり、が容易となる。こうして、シート片１０は、第三辺１３に第四辺１４を所定の間隔で対向または当接させて基材９に略一周巻回される。   Moreover, in the manufacturing method of the sliding member of the present invention, the sheet piece 10 has a direction parallel to the first side 11 and the second side 12 (the length direction of the sheet piece 10) and the circumferential direction of the substrate 9. After matching, the substrate 9 may be wound around the base 9 from the third side 13 side. At this time, the third side 13 and the fourth side 14 are opposed to each other at a predetermined position. Since the sheet piece 10 has a parallelogram shape, the length direction of the sheet piece 10 is slightly inclined with respect to the circumferential direction of the base material 9 (that is, the winding direction is finely adjusted). It is easy to adjust the dimension of the sheet piece 10 that coincides with the circumferential direction of the substrate. Specifically, when the base material 9 and / or the sheet piece 10 is heated and the sheet piece 10 is wound around the base material 9 from the third side 13 side and thermocompression-bonded, the sheet piece 10 contracts. When the length L becomes shorter than the circumferential length L ′ of the base material 9, the first thermocompression bonding is performed sequentially in accordance with the position of the third side 13 already thermocompression bonded to the outer peripheral surface of the base material. By finely adjusting the winding direction on the four sides 14 side, as shown in FIG. 4, the third side 13 and the fourth side 14 are aligned on the same line, and the sheet piece 10 is brought into contact with no gap, As shown in FIG. 5, it is easy to face each other with a gap 15 having a predetermined width between the third side 13 and the fourth side 14. In this way, the sheet piece 10 is wound around the base material 9 substantially once with the fourth side 14 facing or contacting the third side 13 at a predetermined interval.

平行四辺形のシート片を用いれば、一枚の大面積シートから切り出された同一の形状をもつ複数枚のシート片を用いて複数の摺動部材を製造する場合、各シート片に対して熱圧着の条件および巻回方向を同一とすることで、得られる摺動部材の摺動層の寸法のばらつきが低減される。また、熱圧着の条件、あるいは、シート片の寸法や材質にばらつきがあっても、巻回方向に所定の角度をもたせることで、基材の外周面に所望の摺動層を形成することができる。   If parallelogram sheet pieces are used, when manufacturing a plurality of sliding members using a plurality of sheet pieces having the same shape cut out from one large area sheet, heat is applied to each sheet piece. By making the pressure bonding conditions and the winding direction the same, variations in the dimensions of the sliding layer of the resulting sliding member are reduced. In addition, even if there are variations in the thermocompression bonding conditions or the size and material of the sheet pieces, a desired sliding layer can be formed on the outer peripheral surface of the substrate by giving a predetermined angle in the winding direction. it can.

上記の各製造方法は、いずれの方法においても、巻回する方向を僅かに調整するだけで第三辺１３と第四辺１４との位置を調整できるため、摺動層の幅Ｗ’が大きく変化することがない。   In each of the above manufacturing methods, since the positions of the third side 13 and the fourth side 14 can be adjusted only by slightly adjusting the winding direction, the width W ′ of the sliding layer is large. There is no change.

また、図７に、短い方の対角線１１９と第一辺１１１とが成す角θ１および対角線１１９と第二辺１１２とが成す角θ１が９０°を超える平行四辺形のシート片の平面図およびこのシート片を基材に巻回する前の斜視図を示す。平行四辺形のシート片１００は、互いに平行な第一辺１１１および第二辺１１２と、互いに平行な第三辺１１３および第四辺１１４と、で区画される。第一辺１１１および第二辺１１２の長さＬ１は基材９の円周の長さＬ’に略等しく、互いに平行な第一辺１１１と第二辺１１２との距離Ｗ１は摺動層の幅Ｗ’と略等しい。そして、第三辺１１３および第四辺１１４は、第一辺１１１に垂直な方向（すなわち第二辺１１２にも垂直な方向）に対して傾斜する。ここで、摺動層の幅Ｗ’は、本発明の摺動部材の製造方法により得られる摺動部材において、基材の軸方向に延びる摺動層の幅とする。 FIG. 7 is a plan view of a parallelogram sheet piece in which the angle θ 1 formed by the shorter diagonal line 119 and the first side 111 and the angle θ 1 formed by the diagonal line 119 and the second side 112 exceed 90 °. And the perspective view before winding this sheet piece around a base material is shown. The parallelogram sheet piece 100 is partitioned by a first side 111 and a second side 112 that are parallel to each other, and a third side 113 and a fourth side 114 that are parallel to each other. The first side 111 and the length L 1 of the second side 112 substantially equal to the circumferential length L 'of the substrate 9, the distance W 1 of the first side 111 parallel to each other and the second side 112 slides It is approximately equal to the layer width W ′. The third side 113 and the fourth side 114 are inclined with respect to a direction perpendicular to the first side 111 (that is, a direction perpendicular to the second side 112). Here, the width W ′ of the sliding layer is the width of the sliding layer extending in the axial direction of the base material in the sliding member obtained by the manufacturing method of the sliding member of the present invention.

シート片１００においても、シート片１００の長さＬ１がＬ１＝２πｒであれば、シート片１００の第一辺１１１および第二辺１１２に平行な方向（シート片１００の「長さ方向」と略記）と巻回方向とに角度φをもたせて第三辺１１３と第四辺１１４とが接するように巻回したときの巻回径は拡径される。また、シート片１００の長さ方向と巻回方向とに角度−φをもたせて第三辺１１３と第四辺１１４とが接するように巻回したときの巻回径は縮径される。したがって、シート片１００の基材の周方向に一致する方向の寸法は、巻回方向の微調節により調整されやすい。 Also in the sheet piece 100, if the length L 1 of the sheet piece 100 is L 1 = 2πr, the direction parallel to the first side 111 and the second side 112 of the sheet piece 100 (the “length direction” of the sheet piece 100). And the winding diameter when the winding is performed so that the third side 113 and the fourth side 114 are in contact with each other with an angle φ between the winding direction and the winding direction. Further, the winding diameter when the sheet piece 100 is wound so that the third side 113 and the fourth side 114 are in contact with each other with an angle −φ between the length direction and the winding direction of the sheet piece 100 is reduced. Therefore, the dimension in the direction matching the circumferential direction of the base material of the sheet piece 100 is easily adjusted by fine adjustment in the winding direction.

そこで、本発明の摺動部材の製造方法では、シート片１００の第一辺１１１および第二辺１１２と平行な方向（シート片１００の長さ方向）と基材９の略周方向とを一致させる。シート片１００の長さ方向と基材９の略周方向とを一致させるには、基材９の周方向に対するシート片１００の長さ方向に所定の角度をもたせることで、シート片１００を基材９に巻回する方向が微調整されればよい。このとき、シート片１００の長さ方向は、基材９の周方向に対して僅かに角度をもった状態、場合によっては、両方向が一致した状態となるのが望ましい。シート片１００は、平行四辺形であるため、巻回方向を微調整してシート片１００を基材９に一周以上巻回することにより、加熱や加圧によりシート片１００の寸法に変化が生じても、第三辺１１３と第四辺１１４とを当接または所定の間隔で対向させることができる。なお、シート片１００の巻回方向は、熱圧着の際の加熱や加圧の条件に応じたシート片１００の変形量を予め見込んで、微調整されるとよい。   Therefore, in the manufacturing method of the sliding member of the present invention, the direction parallel to the first side 111 and the second side 112 of the sheet piece 100 (the length direction of the sheet piece 100) coincides with the substantially circumferential direction of the substrate 9. Let In order to make the length direction of the sheet piece 100 and the substantially circumferential direction of the base material 9 coincide with each other, the sheet piece 100 is made to have a predetermined angle in the length direction of the sheet piece 100 with respect to the circumferential direction of the base material 9. The direction of winding around the material 9 may be finely adjusted. At this time, it is desirable that the length direction of the sheet piece 100 is slightly inclined with respect to the circumferential direction of the base material 9, and in some cases, both directions coincide with each other. Since the sheet piece 100 is a parallelogram, the dimensions of the sheet piece 100 are changed by heating or pressurization by finely adjusting the winding direction and winding the sheet piece 100 around the substrate 9 one or more times. However, the third side 113 and the fourth side 114 can be brought into contact with each other or opposed to each other at a predetermined interval. Note that the winding direction of the sheet piece 100 may be finely adjusted in advance in consideration of the deformation amount of the sheet piece 100 according to the heating and pressurizing conditions during thermocompression bonding.

また、本発明の摺動部材の製造方法では、シート片１００の第一辺１１１および第二辺１１２と平行な方向（シート片１００の長さ方向）と基材９の周方向とを一致させて、第三辺１１３側より、基材９に一周以上巻回されてもよい。このとき、巻回する方向を微調整して、第三辺１１３と第四辺１１４とを所定の位置で対向させる。シート片１００は、上記の形状をもつため、シート片１００の長さ方向を基材９の周方向に対して僅かに角度をもたせた状態とする（すなわち巻回方向を微調整する）ことで、基材の周方向に一致するシート片１００の寸法を調整し易い。具体的には、基材９および／またはシート片１００を加熱して、シート片１００の第三辺１１３側からシート片１００を基材９に巻回して熱圧着する際、既に熱圧着された第三辺１１３の位置に合わせて巻回方向を微調整することで、図８に示すように第三辺１１３と第四辺１１４とを同一の線上で一致させてシート片１００を隙間無く当接させたり、図９に示すように第三辺１１３と第四辺１１４との間に所定の幅の間隙１１５をもって互いに対向させたり、が容易となる。こうして、シート片１００は、第三辺１１３に第四辺１１４を所定の間隔で対向または当接させて基材９に一周以上巻回される。   Further, in the manufacturing method of the sliding member of the present invention, the direction parallel to the first side 111 and the second side 112 of the sheet piece 100 (the length direction of the sheet piece 100) and the circumferential direction of the base material 9 are matched. Then, the substrate 9 may be wound one or more times from the third side 113 side. At this time, the winding direction is finely adjusted so that the third side 113 and the fourth side 114 are opposed to each other at a predetermined position. Since the sheet piece 100 has the above-described shape, the sheet piece 100 is in a state in which the length direction of the sheet piece 100 is slightly inclined with respect to the circumferential direction of the base material 9 (that is, the winding direction is finely adjusted). It is easy to adjust the dimension of the sheet piece 100 that coincides with the circumferential direction of the substrate. Specifically, when the base material 9 and / or the sheet piece 100 is heated and the sheet piece 100 is wound around the base material 9 from the third side 113 side and thermocompression bonded, the thermocompression bonding has already been performed. By finely adjusting the winding direction according to the position of the third side 113, the third side 113 and the fourth side 114 are aligned on the same line as shown in FIG. As shown in FIG. 9, it is easy to make contact with each other with a gap 115 having a predetermined width between the third side 113 and the fourth side 114. In this way, the sheet piece 100 is wound around the substrate 9 one or more times with the fourth side 114 facing or abutting the third side 113 at a predetermined interval.

平行四辺形のシート片を用いれば、一枚の大面積シートから切り出された同一の形状をもつ複数枚のシート片を用いて複数の摺動部材を製造する場合、各シート片に対して熱圧着の条件および巻回方向を同一とすることで、得られる摺動部材の摺動層の寸法のばらつきが低減される。また、熱圧着の条件、あるいは、シート片の寸法や材質にばらつきがあっても、巻回方向を微調整することで、基材の外周面に所望の摺動層を形成することができる。   If parallelogram sheet pieces are used, when manufacturing a plurality of sliding members using a plurality of sheet pieces having the same shape cut out from one large area sheet, heat is applied to each sheet piece. By making the pressure bonding conditions and the winding direction the same, variations in the dimensions of the sliding layer of the resulting sliding member are reduced. Further, even if there are variations in the thermocompression bonding conditions or the size and material of the sheet pieces, a desired sliding layer can be formed on the outer peripheral surface of the substrate by finely adjusting the winding direction.

上記の各製造方法は、いずれの方法においても、巻回する方向を僅かに調整するだけで第三辺１１３と第四辺１１４との位置を調整できるため、摺動層の幅Ｗ’が大きく変化することがない。   In each of the above manufacturing methods, since the positions of the third side 113 and the fourth side 114 can be adjusted only by slightly adjusting the winding direction, the width W ′ of the sliding layer is large. There is no change.

所定の間隔をもつ間隙１５および間隙１１５は、摺動層において、潤滑油を保持する油保持溝となる。図６は、図５のＸ−Ｘ’における断面図であって、溝部を示す部分拡大図である。間隙１５は、厚みをもつシート片１０の第三辺１３および第四辺１４の端面を壁面とし、シート片１０が熱圧着されずに露出する基材９の外周面を底面とする溝部を構成する。すなわち、本発明の摺動部材の製造方法は、第三辺と第四辺との間に所定の間隔をもたせて対向させ、基材の外周面と第三辺と第四辺とで区画された油保持溝を形成することができる。油保持溝は、溝幅が一定でなかったり、溝幅が極端に広すぎたりすると、摺動性に影響を及ぼす。本発明の摺動部材の製造方法によれば、第三辺と第四辺との間隔を、油保持溝として好適な溝幅に、容易に調整できる。   The gap 15 and the gap 115 having a predetermined interval become oil retaining grooves for retaining lubricating oil in the sliding layer. FIG. 6 is a cross-sectional view taken along the line X-X ′ in FIG. 5, and is a partially enlarged view showing a groove portion. The gap 15 constitutes a groove portion with the end surfaces of the third side 13 and the fourth side 14 of the thick sheet piece 10 as wall surfaces and the outer peripheral surface of the base material 9 where the sheet piece 10 is exposed without being thermocompression bonded as the bottom surface. To do. In other words, the manufacturing method of the sliding member of the present invention is opposed to the third side and the fourth side with a predetermined interval, and is divided by the outer peripheral surface, the third side, and the fourth side of the substrate. An oil retaining groove can be formed. The oil retaining groove affects the slidability if the groove width is not constant or the groove width is extremely wide. According to the method for manufacturing a sliding member of the present invention, the distance between the third side and the fourth side can be easily adjusted to a groove width suitable as an oil retaining groove.

また、本発明の摺動部材の製造方法では、樹脂シートを、両端部に段差部を有する帯状シートとする。図１０に帯状シートの平面図およびこの帯状シートを基材に巻回する前の斜視図を示す。帯状シート２０において、互いに平行な２つの側辺（側辺２１および側辺２２）の長さＬ２は基材９の円周の長さＬ’（＝２πｒ）に略等しく、側辺２１と側辺２２との距離Ｗ２は摺動層の幅Ｗ’と等しい。そして、帯状シート２０は、その両端部に、側辺２１および側辺２２と平行な一対の短辺２３、２３’をもつ段差部２６、２６’を有する。なお、一対の短辺２３および短辺２３’は、帯状シート２０の一端部および他端部に１つずつ位置するが、両者は同一直線上に位置する。すなわち、短辺２３、２３’は、それぞれ、側辺２１（または側辺２２）から等しい距離に位置する。また、側辺２１および側辺２２と平行な方向の帯状シート２０の長さＬ２は、円周の長さＬと略等しい。ただし、帯状シート２０の側辺２１、２２と平行な方向の長さのうち、短辺２３および２３’を含む長さは、帯状シート２０を基材９に巻回したときに短辺が互いに当接して基材９の外周を一周以上するため、Ｌ２よりも長くなる。ここで、端部２６および端部２６’において、辺２３および辺２３’に連続する互いに平行な２組の端辺２８および２８’、端辺２９および２９’は、辺２１や辺２２に垂直であってもよいし、傾斜していてもよい。 Moreover, in the manufacturing method of the sliding member of this invention, let a resin sheet be a strip | belt-shaped sheet which has a level | step-difference part in both ends. FIG. 10 shows a plan view of the belt-like sheet and a perspective view before the belt-like sheet is wound around the base material. In the belt-like sheet 20, the length L 2 of two parallel sides (side 21 and side 22) is substantially equal to the circumferential length L ′ (= 2πr) of the substrate 9, distance W 2 between the sides 22 is equal to the width W 'of the sliding layer. And the strip | belt-shaped sheet | seat 20 has the level | step-difference part 26 and 26 'which has a pair of short side 23 and 23' parallel to the side 21 and the side 22 at the both ends. In addition, although a pair of short side 23 and short side 23 'are each located in the one end part and other end part of the strip | belt-shaped sheet | seat 20, both are located on the same straight line. That is, the short sides 23 and 23 'are located at the same distance from the side 21 (or the side 22). The length L 2 of the side edges 21 and side edge 22 parallel to the direction of the belt-like sheet 20 is substantially equal to the circumferential length L. However, among the lengths in the direction parallel to the side edges 21 and 22 of the belt-like sheet 20, the length including the short sides 23 and 23 ′ is short when the belt-like sheet 20 is wound around the substrate 9. since contact with for more than around the periphery of the substrate 9, it is longer than L 2. Here, in the end portion 26 and the end portion 26 ′, two sets of end sides 28 and 28 ′ that are continuous with the side 23 and the side 23 ′ and the end sides 29 and 29 ′ are perpendicular to the side 21 and the side 22. Or may be inclined.

上記の帯状シート２０は、側辺２１および側辺２２と平行な方向を基材９の周方向に一致させて、基材９の外周面に略一周巻回される。このとき、両端部が互いに対向されるとともに、一対の短辺２３、２３’が当接する。たとえば、帯状シート２０の長さ方向を基材９の周方向に一致させて端部２６側から帯状シート２０を基材９に巻回すると、帯状シート２０が幅方向に変形しにくいことから、短辺２３と短辺２３’とは、図１１に側面図を示すように、帯状シート２０の長さ方向の伸縮に関わらず、互いに当接する。すなわち、帯状シートの長さに関わらず両端部の少なくとも一部が接した状態にできるため、基材の軸方向に連続する隙間の発生を避けられる。そのため、摺動部材の軸方向のシール性が高まる。このような摺動部材は、圧縮機のピストンとして最適である。   The belt-like sheet 20 is wound around the outer peripheral surface of the base material 9 substantially once by making the direction parallel to the side edge 21 and the side edge 22 coincide with the circumferential direction of the base material 9. At this time, both ends are opposed to each other and the pair of short sides 23 and 23 'abut. For example, when the belt-like sheet 20 is wound around the base material 9 from the end 26 side with the length direction of the belt-like sheet 20 aligned with the circumferential direction of the base material 9, the belt-like sheet 20 is not easily deformed in the width direction. The short side 23 and the short side 23 ′ are in contact with each other regardless of expansion and contraction in the length direction of the belt-like sheet 20, as shown in a side view in FIG. That is, since at least a part of both end portions are in contact with each other regardless of the length of the belt-like sheet, it is possible to avoid the generation of a gap continuous in the axial direction of the base material. Therefore, the sealing performance in the axial direction of the sliding member is enhanced. Such a sliding member is optimal as a piston for a compressor.

また、上記の帯状シート２０は、端部に１つずつ一対の短辺をもつが、帯状シートは一対以上の短辺を有してもよい。二対の短辺を有する帯状シートの具体例として、図１２にその平面図を示す。図１２の帯状シート２２０は、図１０の帯状シート２０の段差部２６および２６’を、両端部が互いに嵌り込む凹凸形状とするものである。具体的には、互いに平行な側辺２２１および側辺２２２の長さＬ２は基材９の円周の長さＬ’に略等しく、側辺２２１と側辺２２２との距離Ｗ２は摺動層の幅Ｗ’と等しい。そして、帯状シート２２０は、その両端部に、側辺２２１および側辺２２２と平行な短辺２２３および短辺２２３’、短辺２２４および短辺２２４’をもつ段差部２２６および２２６’を有する。すなわち、段差部２２６および２２６’は、側辺２２１および側辺２２２と平行な短辺２２３および２２３’、短辺２２４および２２４’をもち、これらの各辺は、互いに平行な３組の端辺２２７および２２７’、端辺２２８および２２８’ならびに端辺２２９および２２９’と連続する。また、側辺２２１および側辺２２２と平行な方向の帯状シート２２０の長さＬ２は、略円周の長さと等しい。 Moreover, although said strip | belt-shaped sheet | seat 20 has a pair of short side 1 each in an edge part, a strip | belt-shaped sheet | seat may have a pair or more short side. As a specific example of the belt-like sheet having two pairs of short sides, a plan view thereof is shown in FIG. The belt-like sheet 220 shown in FIG. 12 has stepped portions 26 and 26 ′ of the belt-like sheet 20 shown in FIG. Specifically, the length L 2 of the side 221 and the side 222 parallel to each other is substantially equal to the circumferential length L ′ of the base material 9, and the distance W 2 between the side 221 and the side 222 is slid. It is equal to the dynamic layer width W ′. The belt-like sheet 220 has step portions 226 and 226 ′ having short sides 223 and 223 ′, short sides 224 and short sides 224 ′ parallel to the side 221 and the side 222 at both ends. That is, the step portions 226 and 226 ′ have short sides 223 and 223 ′ and short sides 224 and 224 ′ parallel to the side 221 and the side 222, respectively, and these sides are three sets of end sides parallel to each other. 227 and 227 ′, end sides 228 and 228 ′ and end sides 229 and 229 ′ are continuous. The length L 2 of the side edges 221 and side edge 222 parallel to the direction of the belt-like sheet 220 is equal to the length of the generally circumferential.

上記の帯状シート２００は、側辺２２１および側辺２２２と平行な方向を基材９の周方向に一致させて、基材９の外周面に略一周巻回される。このとき、両端部が互いに対向されるとともに、一対の短辺２２３および短辺２２３’ならびに短辺２２４および短辺２２４’が互いに当接する。すなわち、帯状シートの長さに関わらず両端部の少なくとも一部が接した状態にできる。   The belt-like sheet 200 is wound around the outer peripheral surface of the base material 9 substantially once by making the direction parallel to the side 221 and the side side 222 coincide with the circumferential direction of the base material 9. At this time, both ends are opposed to each other, and the pair of short side 223 and short side 223 'and short side 224 and short side 224' contact each other. That is, at least a part of both end portions can be in contact with each other regardless of the length of the belt-like sheet.

また、これまで説明した帯状シートは、一対の短辺が一方の側辺から等しい距離に位置するため、短辺はそれぞれ同一直線上に位置するが、一方の側辺から異なる距離に位置してもよい。一対の短辺が一方の側辺から異なる距離に位置する帯状シートの具体例として、図１３にその平面図を示す。図１３の帯状シート２００は、段差部の位置が変更されているほかは図１０の帯状シート２０と同様である。具体的には、帯状シート２００の短辺２３０および２３０’は、帯状シート２０の短辺２３および短辺２３’と幅方向に位置が異なる。そのため、帯状シートのうち短辺を含む直線に挟まれる範囲では、側辺と平行な方向の帯状シートの長さが略円周の長さと等しくならない。図１４は、帯状シート２００を基材９に巻回した側面図である。基材９に帯状シート２００を巻回すると、帯状シート２００の短辺２３０および短辺２３０’は、互いに所定の間隙２５０をもって対向する（図１４）。   Further, in the belt-like sheet described so far, since the pair of short sides are located at the same distance from one side, the short sides are located on the same straight line, but are located at different distances from one side. Also good. As a specific example of a belt-like sheet in which a pair of short sides are located at different distances from one side, a plan view thereof is shown in FIG. The belt-like sheet 200 in FIG. 13 is the same as the belt-like sheet 20 in FIG. 10 except that the position of the step portion is changed. Specifically, the positions of the short sides 230 and 230 ′ of the belt-like sheet 200 are different in the width direction from the short sides 23 and 23 ′ of the belt-like sheet 20. Therefore, the length of the belt-like sheet in the direction parallel to the side is not equal to the length of the circumference in the range sandwiched by the straight line including the short side of the belt-like sheet. FIG. 14 is a side view of the belt-like sheet 200 wound around the base material 9. When the belt-like sheet 200 is wound around the base material 9, the short side 230 and the short side 230 'of the belt-like sheet 200 face each other with a predetermined gap 250 (FIG. 14).

本発明の摺動部材の製造方法においても、図１４の間隙２５０のように、一対の短辺２３０および２３０’を互いに所定の間隔をもたせて対向させて、潤滑油を保持する油保持溝を形成することができる。油保持溝は、溝幅が一定でなかったり、溝幅が極端に広すぎたりすると、摺動性に影響を及ぼす。本発明の摺動部材の製造方法によれば、基材の周方向に伸びる間隙を油保持溝として好適な溝幅に、容易に調整できる。このような摺動部材は、エンジン、モータ、圧縮機などのドライブシャフトとして最適である。   Also in the manufacturing method of the sliding member of the present invention, as in the gap 250 in FIG. 14, the pair of short sides 230 and 230 ′ are opposed to each other with a predetermined interval to form an oil holding groove for holding the lubricating oil. Can be formed. The oil retaining groove affects the slidability if the groove width is not constant or the groove width is extremely wide. According to the method for manufacturing a sliding member of the present invention, the gap extending in the circumferential direction of the substrate can be easily adjusted to a groove width suitable as an oil retaining groove. Such a sliding member is optimal as a drive shaft for engines, motors, compressors, and the like.

樹脂シートを熱圧着する方法に特に限定はなく、樹脂シートの少なくとも基材と接触する側の表面部を適度な温度に加熱した状態で加圧することで、樹脂シートを基材の外周面に固定できる。温度や加圧の条件に特に限定はなく、樹脂シートの材質に応じて適宜選択すればよい。たとえば、温度条件としては、樹脂シートの少なくとも基材と接触する表面部の弾性率が適度に低下して接着に適切な流動性を示す程度の温度に保持されるとよい。樹脂シートの少なくとも基材と接触する表面部を加熱するには、樹脂シート自体を加熱してもよいし、基材の少なくとも外周面側を加熱してもよいし、樹脂シートと基材の両方を加熱してもよい。   There is no particular limitation on the method of thermocompression bonding the resin sheet, and the resin sheet is fixed to the outer peripheral surface of the substrate by pressing at least the surface portion of the resin sheet that is in contact with the substrate while being heated to an appropriate temperature. it can. There are no particular limitations on the temperature and pressure conditions, and the conditions may be appropriately selected according to the material of the resin sheet. For example, as a temperature condition, it is good to hold | maintain the temperature of the grade which the elasticity modulus of the surface part which contacts at least a base material of a resin sheet falls moderately, and shows fluidity | liquidity suitable for adhesion | attachment. In order to heat at least the surface portion of the resin sheet that contacts the base material, the resin sheet itself may be heated, at least the outer peripheral surface side of the base material may be heated, or both the resin sheet and the base material may be heated. May be heated.

また、樹脂シートは、基材および／または樹脂シートを加熱してから、基材に加圧しつつ巻回されて熱圧着されてもよいし、基材に巻回されてから加圧しつつ加熱して熱圧着されてもよい。熱圧着に関しては、樹脂シートおよび基材の形状や材質に応じた最適な方法を選択すればよい。たとえば、樹脂シートが平行四辺形のシート片であれば、少なくともシート片を予め加熱することで、先に基材に巻回されたシート片の一部が熱圧着されるとともに、順次巻回されてゆくシート片の残部の巻回方向を容易に微調整できる。   In addition, the resin sheet may be heated and pressure-bonded after being heated on the substrate and / or the resin sheet, and then heated while being pressed after being wound on the substrate. May be thermocompression bonded. Regarding thermocompression bonding, an optimal method may be selected in accordance with the shape and material of the resin sheet and the substrate. For example, if the resin sheet is a parallelogram sheet piece, at least the sheet piece is preheated so that a part of the sheet piece previously wound on the substrate is thermocompression-bonded and sequentially wound. The winding direction of the remaining sheet piece can be finely adjusted easily.

また、樹脂シートを巻回する方法に特に限定はない。たとえば、温度調節が可能なステージに基材と樹脂シートを載置し、ステージ（樹脂シート）と基材とを相対移動させることで、樹脂シートは基材の外周面に巻き取られて巻回される。この際、基材は円形の断面を有するため、回転しつつ移動する。さらに、基材をステージに対して押圧することで、熱圧着が可能となる。このとき、巻回方向は、ステージと基材とが相対移動する方向を変更して、樹脂シート（シート片）の長さ方向と基材の周方向との間に僅かに角度をつけることで、微調整される。また、樹脂シート（シート片）にテンションをかけながら基材に巻回する場合には、テンションをかける方向を変更することで、巻回方向が微調整される。   Moreover, there is no limitation in particular in the method of winding a resin sheet. For example, by placing a base material and a resin sheet on a temperature adjustable stage and moving the stage (resin sheet) and the base material relative to each other, the resin sheet is wound around the outer peripheral surface of the base material. Is done. At this time, since the substrate has a circular cross section, it moves while rotating. Furthermore, thermocompression bonding is possible by pressing the substrate against the stage. At this time, the winding direction is changed by changing the direction in which the stage and the base material relatively move, and a slight angle is formed between the length direction of the resin sheet (sheet piece) and the circumferential direction of the base material. Tweaked. In addition, when the resin sheet (sheet piece) is wound around the substrate while applying tension, the winding direction is finely adjusted by changing the direction in which the tension is applied.

以上、本発明の摺動部材の製造方法の実施形態を説明したが、本発明は、上記実施形態に限定されるものではない。本発明の要旨を逸脱しない範囲において、当業者が行い得る変更、改良等を施した種々の形態にて実施することができる。   As mentioned above, although embodiment of the manufacturing method of the sliding member of this invention was described, this invention is not limited to the said embodiment. The present invention can be implemented in various forms without departing from the gist of the present invention, with modifications and improvements that can be made by those skilled in the art.

上記実施形態に基づいて、基材の表面に樹脂シートを熱圧着して摺動部材を作製した。以下に本発明の摺動部材の製造方法を示す。   Based on the said embodiment, the resin sheet was thermocompression-bonded to the surface of the base material, and the sliding member was produced. The manufacturing method of the sliding member of this invention is shown below.

基材として、直径２０ｍｍの丸棒（Ｓ４５Ｃ鋼）を用いた。基材の外周面は、表面粗さが４〜５μｍＲｚとなるようにショットブラスト処理を施した。以下の手順で、基材の外周面に摺動層を形成した。   A round bar (S45C steel) having a diameter of 20 mm was used as the substrate. The outer peripheral surface of the base material was shot blasted so that the surface roughness was 4 to 5 μm Rz. The sliding layer was formed in the outer peripheral surface of a base material with the following procedures.

［比較例１］
ポリアミドイミド（ＰＡＩ）樹脂をｎ−メチル−２−ピロリドンに溶解したＰＡＩ樹脂ワニスに、固体潤滑剤として二硫化モリブデンおよびグラファイトを加えて攪拌後、３本ロールを２回通して混錬して、コーティング液を得た。なお、固形分の配合量は、ＰＡＩ樹脂７０ｗｔ％、二硫化モリブデン２０ｗｔ％、グラファイト１０ｗｔ％に調製した。 [Comparative Example 1]
To a PAI resin varnish obtained by dissolving polyamideimide (PAI) resin in n-methyl-2-pyrrolidone, molybdenum disulfide and graphite are added as a solid lubricant and stirred, and then kneaded by passing three rolls twice. A coating solution was obtained. The solid content was adjusted to 70 wt% PAI resin, 20 wt% molybdenum disulfide, and 10 wt% graphite.

このコーティング液をエアスプレーにて噴霧して、基材の外周面に膜厚２０μｍの塗膜を付着させた。その後、１８０℃で９０分焼成して、基材の外周面に摺動層を形成し、摺動部材を得た。   This coating solution was sprayed by air spray to attach a coating film having a thickness of 20 μm to the outer peripheral surface of the substrate. Then, it baked at 180 degreeC for 90 minutes, the sliding layer was formed in the outer peripheral surface of a base material, and the sliding member was obtained.

得られた摺動部材の摺動面（摺動層の表面）の表面粗さは、２．２μｍＲｚであった。   The surface roughness of the sliding surface (the surface of the sliding layer) of the obtained sliding member was 2.2 μmRz.

［参考例１］
樹脂フィルムとして、基材の円周の長さよりも長い帯状で矩形に切り出されたＰＥＥＫ樹脂フィルム（厚さ５０μｍ）を準備した。基材を３７０℃に加熱し、基材の外周面にＰＥＥＫ樹脂フィルムを基材に対して加圧しながら一周させて熱圧着し、摺動部材を得た。基材の外周面に付着せずに残った部分は、カッターで切り揃えた。 [Reference Example 1]
As a resin film, a PEEK resin film (thickness: 50 μm) cut out in a rectangular shape with a strip shape longer than the circumference of the substrate was prepared. The base material was heated to 370 ° C., and a PEEK resin film was applied to the outer peripheral surface of the base material while being pressed against the base material, followed by thermocompression bonding to obtain a sliding member. The portion that remained without adhering to the outer peripheral surface of the substrate was trimmed with a cutter.

得られた摺動部材の摺動面（摺動層の表面）の表面粗さは、０．２μｍＲｚであった。   The surface roughness of the sliding surface (the surface of the sliding layer) of the obtained sliding member was 0.2 μm Rz.

［参考例２］
樹脂フィルムとして、基材の円周の長さよりも長い帯状で矩形に切り出された積層フィルム（厚さ５０μｍ）を準備した。積層フィルムは、ＰＥＥＫ樹脂からなる表面層とＰＥＥＫ樹脂とＰＥＩ樹脂とからなる接着層との二層からなり共押出により作製された。基材を２７０℃に加熱し、基材の外周面に接着層を接触させた状態で、積層フィルムを基材に対して加圧しながら一周させて熱圧着し、摺動部材を得た。基材の外周面に付着せずに残った部分は、カッターで切り揃えた。 [Reference Example 2]
As the resin film, a laminated film (thickness: 50 μm) cut out in a rectangular shape with a strip shape longer than the circumferential length of the substrate was prepared. The laminated film consisted of two layers of a surface layer made of PEEK resin and an adhesive layer made of PEEK resin and PEI resin, and was produced by coextrusion. The base material was heated to 270 ° C., and with the adhesive layer being in contact with the outer peripheral surface of the base material, the laminated film was heated and pressed under pressure against the base material to obtain a sliding member. The portion that remained without adhering to the outer peripheral surface of the substrate was trimmed with a cutter.

得られた摺動部材の摺動面（摺動層の表面）の表面粗さは、０．３μｍＲｚであった。   The surface roughness of the sliding surface (the surface of the sliding layer) of the obtained sliding member was 0.3 μm Rz.

［評価］
ジャーナル試験機を用い、比較例１および参考例１および２の手順で作製した摺動部材の摺動性を評価した。摺動面に潤滑油を塗布し、試験条件は、すべり速度６．０ｍ／ｓｅｃ、荷重２０００Ｎ、試験時間２０秒で行った。 [Evaluation]
Using a journal testing machine, the slidability of the sliding members produced by the procedures of Comparative Example 1 and Reference Examples 1 and 2 was evaluated. Lubricating oil was applied to the sliding surface, and the test conditions were a sliding speed of 6.0 m / sec, a load of 2000 N, and a test time of 20 seconds.

試験後の摺動部材の表面を目視により確認したところ、参考例１および２で作製した摺動部材では、摺動層に摩耗は認められなかった。一方、比較例１で作製した摺動部材では、摺動層が大きく摩耗した。すなわち、樹脂フィルムを熱圧着して形成した摺動層をもつ摺動部材は、摺動性に優れた。表面が平滑な樹脂フィルムは、摺動層として基材の表面に固定された後も、平滑性を失うことなく熱圧着されたためである。   When the surface of the sliding member after the test was visually confirmed, the sliding member produced in Reference Examples 1 and 2 showed no wear on the sliding layer. On the other hand, in the sliding member produced in Comparative Example 1, the sliding layer was greatly worn. That is, a sliding member having a sliding layer formed by thermocompression bonding of a resin film was excellent in slidability. This is because the resin film having a smooth surface was thermocompression bonded without losing smoothness even after being fixed to the surface of the substrate as a sliding layer.

［比較例２］
樹脂フィルムとして、対向する一対の辺の長さが基材の円周の長さに等しい長方形のＰＥＥＫ樹脂フィルム（厚さ５０μｍ）を準備した。長方形のＰＥＥＫ樹脂フィルムの一方の面には、エポキシ系の接着剤を塗布した。一方、基材は、１２０℃に加熱された。ＰＥＥＫ樹脂フィルムの長手方向と基材の軸方向とが垂直となるように、ＰＥＥＫ樹脂フィルムの上に基材を配置し、ＰＥＥＫ樹脂フィルムに基材を押圧させながら基材を回転させて、基材の外周面にＰＥＥＫ樹脂フィルムを巻き取らせて巻回した。このとき、ＰＥＥＫ樹脂フィルムは、接着剤が塗布された面が基材側に位置するようにして巻回された。こうして、ＰＥＥＫ樹脂フィルムを基材の表面に熱圧着し、摺動部材を得た。 [Comparative Example 2]
As a resin film, a rectangular PEEK resin film (thickness: 50 μm) having a pair of opposing sides equal in length to the circumference of the substrate was prepared. An epoxy adhesive was applied to one surface of the rectangular PEEK resin film. On the other hand, the substrate was heated to 120 ° C. The base material is arranged on the PEEK resin film so that the longitudinal direction of the PEEK resin film is perpendicular to the axial direction of the base material, and the base material is rotated while pressing the base material against the PEEK resin film. The PEEK resin film was wound around the outer peripheral surface of the material and wound. At this time, the PEEK resin film was wound so that the surface on which the adhesive was applied was positioned on the substrate side. Thus, the PEEK resin film was thermocompression bonded to the surface of the base material to obtain a sliding member.

ＰＥＥＫ樹脂フィルムを巻回する際に巻回方向を微調節しても、巻回されて対向する２辺の間隔を任意の一定の幅に調整することが困難であった。   Even if the winding direction is finely adjusted when the PEEK resin film is wound, it is difficult to adjust the distance between the two sides that are wound and face each other to an arbitrary constant width.

［実施例１］
樹脂フィルムとして、各辺の長さが基材の円周方向の長さに等しく、向かい合う一対の角が３０°の菱形のＰＥＥＫ樹脂フィルム（厚さ５０μｍ）を準備した。菱形のＰＥＥＫ樹脂フィルムの一方の面には、エポキシ系の接着剤を塗布した。一方、基材は、１２０℃に加熱された。ＰＥＥＫ樹脂フィルムの長手方向と基材の軸方向とが垂直となるように、ＰＥＥＫ樹脂フィルムの上に基材を配置し、ＰＥＥＫ樹脂フィルムに基材を押圧させながら基材を回転させて、基材の外周面にＰＥＥＫ樹脂フィルムを巻き取らせて巻回した。このとき、ＰＥＥＫ樹脂フィルムは、接着剤が塗布された面が基材側に位置するようにして巻回された。こうして、ＰＥＥＫ樹脂フィルムを基材の表面に熱圧着し、摺動部材を得た。 [Example 1]
As the resin film, a rhombus PEEK resin film (thickness: 50 μm) having a side length equal to the circumferential length of the base material and a pair of opposite corners of 30 ° was prepared. An epoxy adhesive was applied to one surface of the rhombus PEEK resin film. On the other hand, the substrate was heated to 120 ° C. The base material is arranged on the PEEK resin film so that the longitudinal direction of the PEEK resin film is perpendicular to the axial direction of the base material, and the base material is rotated while pressing the base material against the PEEK resin film. The PEEK resin film was wound around the outer peripheral surface of the material and wound. At this time, the PEEK resin film was wound so that the surface on which the adhesive was applied was positioned on the substrate side. Thus, the PEEK resin film was thermocompression bonded to the surface of the base material to obtain a sliding member.

ＰＥＥＫ樹脂フィルムを巻回する際に巻回方向を微調節することにより、フィルムの周方向の伸縮量に関わらず、巻回されて対向する２辺の間隔を任意の一定の幅に容易に調整することができた。   By finely adjusting the winding direction when winding the PEEK resin film, the distance between the two sides that are wound and facing each other can be easily adjusted to any fixed width regardless of the amount of expansion or contraction in the circumferential direction of the film. We were able to.

［実施例２］
樹脂フィルムとして、帯状のＰＥＥＫ樹脂フィルム（厚さ５０μｍ）を準備した。このＰＥＥＫ樹脂フィルムは、図１０の上図に示す帯状フィルム２０と同様の形状とした。帯状のＰＥＥＫ樹脂フィルムの長さＬ２は基材の円周方向の長さと等しくし、側辺２１および２２から等しい距離にある短辺２３および２３’の長さを１５ｍｍとした。帯状のＰＥＥＫ樹脂フィルムの一方の面には、エポキシ系の接着剤を塗布した。一方、基材は、１２０℃に加熱された。ＰＥＥＫ樹脂フィルムに基材を押圧させながら基材を回転させて、基材の外周面にＰＥＥＫ樹脂フィルムを巻き取らせて巻回した。このとき、ＰＥＥＫ樹脂フィルムは、接着剤が塗布された面が基材側に位置するようにして巻回された。こうして、ＰＥＥＫ樹脂フィルムを基材の表面に熱圧着し、摺動部材を得た。 [Example 2]
A belt-like PEEK resin film (thickness: 50 μm) was prepared as the resin film. This PEEK resin film had the same shape as the strip film 20 shown in the upper diagram of FIG. The length L 2 of the band-like PEEK resin film is equal to the length of the circumferential direction of the substrate, the length of the short side 23 and 23 'at a distance equal to the sides 21 and 22 was set to 15 mm. An epoxy adhesive was applied to one side of the belt-like PEEK resin film. On the other hand, the substrate was heated to 120 ° C. The base material was rotated while pressing the base material against the PEEK resin film, and the PEEK resin film was wound around the outer peripheral surface of the base material and wound. At this time, the PEEK resin film was wound so that the surface on which the adhesive was applied was positioned on the substrate side. Thus, the PEEK resin film was thermocompression bonded to the surface of the base material to obtain a sliding member.

フィルムの周方向の伸縮量に関わらず、短辺２３および短辺２３’を同一の円周上に位置させて互いに当接させることができた（図１１）。   Regardless of the amount of expansion and contraction in the circumferential direction of the film, the short side 23 and the short side 23 'could be positioned on the same circumference and brought into contact with each other (FIG. 11).
