Abstract
【解決手段】深溝玉軸受用の保持器5は、油潤滑条件で使用される深溝玉軸受において内外輪間に介在する複数のボールを保持するものであり、少なくともボールと摺動する部位に10μm以上の厚さのフッ素樹脂被膜6が形成されてなり、このフッ素樹脂被膜6が、フッ素樹脂としてポリテトラフルオロエチレンとテトラフルオロエチレン−ヘキサフルオロプロピレン共重合体を含む焼成フッ素樹脂被膜である。
【選択図】図2
Description
表1に記載の材質(厚さ1mmのSPCC)の金属平板表面にフッ素樹脂被膜を形成した。このフッ素樹脂被膜は、フッ素樹脂としてPTFEとFEPを含むものであり、塗布形成後に90℃の恒温槽内で30分間乾燥し、380℃の加熱炉内で30分間焼成した。このフッ素樹脂被膜が形成された金属平板を用いて、フッ素樹脂被膜がポケット内面になるようにして、図2に示す鋲加締め波型鉄板保持器を作製した。この保持器を用いて、略同一ラジアルすきまを有する深溝玉軸(6206C3)を作製した。
<耐久試験条件>
回転速度:3000RPM
モーメント荷重:19.6N・m
潤滑:潤滑剤が全く存在しない完全脱脂の状態
試験個数:各3個
比較例1は保持器のポケット面にフッ素樹脂被膜がされていない標準深溝玉軸受(6206C3)、比較例2は保持器の材料をSUS(ステンレス)に代える以外は比較例1と同一の深溝玉軸受である。
比較例3〜比較例6は、表1に示す構成の相違以外は、実施例1と同一の深溝玉軸受である。比較例3〜比較例6は、実施例1と同様の基材に対して、フッ素樹脂がPTFEのみであるフッ素樹脂被膜を形成して保持器を作製している。また、これら比較例内で焼成の有無と膜厚が異なる。
実施例1と同一のフッ素樹脂被膜を形成した金属平板の試験片を実施例2とし、比較例3と同一のフッ素樹脂被膜を形成した金属平板の試験片を比較例7とし、これらを用いて以下に示す条件で摩擦抵抗試験を行なった。結果を表2に示す。
<摩擦係数測定条件>
装置:新東科学製表面測定機:トライボギア14FW
相手材:5mmφ SUS球
荷重:1kg
摩耗速度:2400mm/min
摩耗距離:10mm往復摩耗
往復回数:10000回
温度:室温
無潤滑環境:潤滑剤が全く存在しない完全脱脂の状態
オイル環境:防錆油塗布(希薄潤滑:油膜パラメータΛ1.0)
実施例1と同様に作製した深溝玉軸受を実施例3とし、比較例3と同様に作製した深溝玉軸受を比較例8とし、これらを用いて以下に示す条件で軸受起動トルク試験を行なった。結果を表3に示す。
<軸受起動トルク試験条件>
試験軸受:6206
潤滑:防錆油塗布(希薄潤滑:油膜パラメータΛ1.0)
温度:室温
試験個数:5個(表の値は5個の平均値)
