Description
(1)樹脂材料
ポリアミド樹脂A:テレフタル酸と1,10−デカンジアミンを主原料に使用した樹脂(ユニチカ社製XecoT XN500)
ポリアミド66樹脂:東レ社製アミランCM3001
ポリアミド46樹脂:DSM社製スタニールTW300
ポリアミド9T樹脂:クラレ社製ジェネスタN1000
(2)繊維状補強材
ガラス繊維:旭ファイバーグラス社製03JAFT692(平均繊維径10μm、平均繊維長3mm)
炭素繊維:東邦テナックス社製HTA−C6(平均繊維径7μm、平均繊維長6mm)
これらの原材料を表1に示す割合で配合した樹脂組成物を用いて、実施例と比較例のアンギュラ玉軸受用保持器を作製し、各種の試験を実施した。組成物の製造には二軸押出機を用いた。ガラス繊維、炭素繊維は折損を防止するために定量サイドフィーダーを用いて供給し、押し出して造粒した。得られた成形用ペレットを用い、インラインスクリュー式射出成形機にて成形し、所望の保持器形状(外径93mm、内径88mm、幅13mm)とした。なお、保持器の形状は図2に示すもみ抜き型保持器とした。成形後、80℃、95%相対湿度の雰囲気にて調湿処理を実施し、吸水させたものについて各試験を実施した。得られた保持器の調湿前後の重量から以下に示す算出式により吸水率を測定した。結果を表1に示す。
吸水率(重量%)=(調湿後の重量−調湿前の重量)×100/調湿前の重量
本発明の保持器における破壊強さ(ウエルド部の引張強度)を確認するため、作製した保持器を用いて保持器引張試験を実施した。保持器引張試験は、図4に示す円環状の引張治具13に試験用の保持器14を、そのウエルド部が水平位置になるようにセットし、島津製作所社製の引張試験機(オートグラフAG50KNX)を用いて10mm/minの引張速度で行なった。結果を表1に示す。
アンギュラ玉軸受を使用してdm・n値80×104まで順次回転数を上げていく軸受試験を実施した。実施例および比較例の保持器を組み込み、潤滑剤としてのグリースを封入し、両側に非接触型シールを設けて密封したアンギュラ玉軸受を用いて比較試験を行なった。試験では外輪温度を測定し、その上昇温度が、精度や耐久性を鑑み、30℃までを基準とし、30℃未満を合格、30℃以上温度が上昇したものを不合格とした。結果を表1に示す。
