Description
図1は、一実施形態に係るコンプレッサー1の構造を示す断面模式図である。コンプレッサー1は、いわゆる斜板式コンプレッサーである。コンプレッサー1は、シャフト2、斜板3、ピストン4、およびシュー5を有する。シャフト2は、ハウジング(図示略)に対して回転可能に支持されている。斜板3は、シャフト2の回転軸に対して斜めに固定されている。斜板3は、本発明に係る摺動部材の一例である。ピストン4は、ハウジングに設けられたシリンダボア(図示略)内を往復運動する。シュー5は、斜板3とピストン4との間に設けられており、斜板3およびピストン4とそれぞれ摺動する。シュー5において、斜板3と摺動する面はほぼ平坦であり、ピストン4と摺動する面はドーム状(半球状)の形状を有している。シュー5は、本発明に係る摺動部材と摺動する相手材の一例である。シャフト2の回転は、斜板3によりピストン4の往復運動に変換される。
種々の条件で摺動部材の試験片を作製し、これらの特性を評価した。摺動部材の基材としては鋳鉄を用い、これを図1のような斜板の形状に加工した。この基材の上に、表1に記載される樹脂組成物でコーティング層を形成した。バインダー樹脂としてはPAIを用いた。なお、実験例3は、MoS2の平均粒径がPTFEの平均粒径よりも大きい例であると言える。
