Abstract
Description
繊維部材は、繊維(A)で形成されており、この繊維(A)は、少なくとも吸水性繊維(吸水性繊維(A1)、繊維(A1)などということがある)を含む。
本発明の繊維部材は、伝動ベルト(摩擦伝動部を有する伝動ベルト)の摩擦伝動部(動力伝達部)の表面[すなわち、摩擦伝動面(又は動力伝達面)]を被覆するための繊維部材として有用である。そのため、本発明には、このような繊維部材を備えた伝動ベルトも含まれる。すなわち、本発明の伝動ベルトは、摩擦伝動部を有し、この摩擦伝動部の表面(摩擦伝動面)が前記繊維部材で被覆された伝動ベルトである。なお、摩擦伝動面は、プーリに接触可能な面(ベルトの腹面)である。そのため、摩擦伝動面は、繊維部材を介してプーリに接触可能となる。
圧縮層は、通常、ゴム(又はゴム組成物)で形成してもよい。ゴム(ゴム組成物を構成するゴム)としては、公知のゴム成分及び/又はエラストマー、例えば、ジエン系ゴム(天然ゴム、イソプレンゴム、ブタジエンゴム、クロロプレンゴム、スチレンブタジエンゴム(SBR)、アクリロニトリルブタジエンゴム(ニトリルゴム)、水素化ニトリルゴム(水素化ニトリルゴムと不飽和カルボン酸金属塩との混合ポリマーを含む)など)、エチレン-α-オレフィンエラストマー、クロロスルフォン化ポリエチレンゴム、アルキル化クロロスルフォン化ポリエチレンゴム、エピクロルヒドリンゴム、アクリル系ゴム、シリコーンゴム、ウレタンゴム、フッ素ゴムなどが例示できる。これらのポリマー成分は単独又は組み合わせて使用することができる。これらのポリマー成分のうち、有害なハロゲンを含まず、耐オゾン性、耐熱性、耐寒性を有し、経済性にも優れる点から、エチレン-α-オレフィンエラストマー(エチレン-プロピレンゴム(EPR)、エチレン-プロピレン-ジエンゴム(EPDMなど)などのエチレン-α-オレフィン系ゴム)が好ましい。
心線は、特に限定されず、例えば、ポリエステル繊維(ポリアルキレンアリレート系繊維)、ポリアミド繊維(アラミド繊維など)などの合成繊維、炭素繊維などの無機繊維などを含んでいてもよい。
伸張層は、圧縮層と同様のゴム組成物で形成してもよく、帆布などの布帛(補強布)で形成してもよい。
接着層は、前記の通り、必ずしも必要ではない。接着層(接着ゴム層)は、例えば、前記圧縮層(圧縮ゴム層)と同様のゴム組成物(エチレン-α-オレフィンエラストマーなどのゴム成分を含むゴム組成物)で構成できる。接着層のゴム組成物において、ゴム成分としては、前記圧縮ゴム層のゴム組成物のゴム成分と同系統又は同種のゴムを使用する場合が多い。また、加硫剤又は架橋剤、共架橋剤又は架橋助剤、加硫促進剤などの添加剤の割合も、それぞれ、前記圧縮層のゴム組成物と同様の範囲から選択できる。接着層のゴム組成物は、さらに接着性改善剤(レゾルシン-ホルムアルデヒド共縮合物、アミノ樹脂など)を含んでいてもよい。
先ず、内型として外周面に可撓性ジャケットを装着した円筒状内型を用い、外周面の可撓性ジャケットに未加硫の伸張層用シートを巻きつけ、このシート上に心線を螺旋状にスピニングし、さらに未加硫の圧縮層用シートと繊維部材とを巻き付けて積層体を作製する。次に、前記内型に装着可能な外型として、内周面に複数のリブ型が刻設された筒状外型を用い、この外型内に、前記積層体が巻き付けられた内型を、同心円状に設置する。その後、可撓性ジャケットを外型の内周面(リブ型)に向かって膨張させて積層体(圧縮層)をリブ型に圧入し、加硫する。そして、外型より内型を抜き取り、複数のリブを有する加硫ゴムスリーブを外型から脱型した後、カッターを用いて、加硫ゴムスリーブをベルト長手方向に所定の幅にカットしてVリブドベルトに仕上げる。この第1の製造方法では、伸張層、心線、圧縮層を備えた積層体を一度に膨張させて複数のリブを有するスリーブ(又はVリブドベルト)に仕上げることができる。
第1の製造方法に関連して、例えば、日本国特開2004-82702号公報に開示される方法(圧縮層のみを膨張させて予備成形体(半加硫状態)とし、次いで伸張層と心線とを膨張させて前記予備成形体に圧着し、加硫一体化してVリブドベルトに仕上げる方法)を採用してもよい。
界面活性剤による処理前後及び加硫前後において、繊維部材及びベルトの質量を測定し、以下の式から、加硫前の繊維部材1m2あたりの界面活性剤の付着量(含有量)WN(g/m2)および加硫後の繊維部材1m2あたりの界面活性剤の付着量(含有量)WR(g/m2)を求めた。
WR=(R2-R1)/SR(g/m2)
(式中、N1は付着処理前の繊維部材(繊維部材の本体)の質量、N2は付着処理後の繊維部材の質量、SNは繊維部材の面積、R1は付着処理を行わなかったベルトの加硫後の質量、R2は付着処理を行ったベルトの加硫後の質量、SRはベルトにおける繊維部材の面積を示す。)
ベルトの摩擦伝動面と水との接触角θ(水滴の端点における接線と摩擦伝動面とがなす角)は、図2に示すように、摩擦伝動面に水を滴下した水滴の投影写真から、θ/2法を用いて以下の式より求めることができる。
tanθ1=h/r → θ1=tan-1(h/r) …(2)
(式中、θ1は、摩擦伝動面に対して、水滴の端点(図2では左端点)と頂点とを結ぶ直線の角度であり、hは水滴の高さ、rは水滴の半径を示す。)
通常走行時(DRY)の摩擦係数の測定には、図3にレイアウトを示すように、直径121.6mmの駆動プーリ(Dr.)、直径76.2mmのアイドラープーリ(IDL.1)、直径61.0mmのアイドラープーリ(IDL.2)、直径76.2mmのアイドラープーリ(IDL.3)、直径77.0mmのアイドラープーリ(IDL.4)、直径121.6mmの従動プーリ(Dn.)を順に配置した試験機を用いた。
T2=180(N/6Rib)
α=π/9(rad)(式中、radはラジアンを意味する)
高温低張力逆曲げ試験は、図5にレイアウトを示すように、直径120mmの駆動プーリ(Dr.)、直径75mmのアイドラープーリ(IDL.)、直径120mmの従動プーリ(Dn.)、直径60mmのテンションプーリ(Ten.)を順に配置した試験機を用いて行なった。すなわち、試験機の各プーリにVリブドベルトを掛架し、駆動プーリの回転数を4900rpm、アイドラープーリ及びテンションプーリへのベルト巻き付け角度を90°、従動プーリ負荷を10.4kWとし、一定荷重[91kg/6Rib(リブ)]を付与してベルトを雰囲気温度120℃で走行させた。
A:300時間で1~5個の亀裂が発生
B:300時間で6個以上(平均でリブ1個あたり1個以上)の亀裂が発生
ミスアライメント発音評価試験(発音限界角度)は、図6にレイアウトを示すように、直径101mmの駆動プーリ(Dr.)、直径80mmのアイドラープーリ(IDL.1)、直径128mmのミスアライメントプーリ(W/P)、直径80mmのアイドラープーリ(IDL.2)、直径61mmのテンションプーリ(Ten.)、直径80mmのアイドラープーリ(IDL.3)を順に配置した試験機を用いて行った。また、アイドラープーリ(IDL.1)とミスアライメントプーリの軸離(スパン長)を135mmに設定し、全てのプーリが同一平面上(ミスアライメントの角度0°)に位置するように調整した。
A:発音角度が2°以上3°未満(静粛性良好)
B:発音角度が2°未満(静粛性悪い)
なお、通常、3°付近でベルトがプーリからはずれて(すなわち、リブずれとなり)正常に動力伝達しない状態になる。
