Description
PEEK樹脂を射出成形して、円筒部材を得た。この円筒部材をSUJ2製の内輪の内周面に嵌合して、さらに、その円筒部材の内周面にSUS304製の割ブッシュを嵌合して、図2に示す形態の試験用部材を得た。
PEEK樹脂を射出成形して、外周面がテーパ状の円筒部材を得た。この円筒部材をSUJ2製の内輪の内周面に嵌合し、さらに、その円筒部材の内周面にSUS304製の割ブッシュを嵌合して、図3に示す形態の試験部材を得た。
オーステナイト系ステンレス鋼製の円筒部材の外周面に大気プラズマ溶射を行ない、セラミックス溶射被膜を有する絶縁ブッシュを得た。溶射材には、アルミナを使用した。
PEEK樹脂を射出成形して、絶縁部単体からなる絶縁ブッシュを得た。この絶縁ブッシュをSUJ2製の内輪の内周面に嵌合して、図5(a)に示す形態の試験部材を得た。
SUS304製の円筒部材の内周面にアマルファ処理を施して微細凹凸形状を形成した後、その内周面にPPS樹脂をインサート成形して、射出成形層を有する絶縁ブッシュを得た。この絶縁ブッシュをSUJ2製の内輪の内周面に嵌合して、図5(b)に示す形態の試験部材を得た。
各試験部材の軸孔にS45製の軸を挿入したものを恒温槽に入れ、熱衝撃を繰り返し加えた。熱衝撃は、160℃、30分の高温条件と、-30℃、30分の低温条件を1セットとして200サイクル行った。200サイクル後に軸を抜き、その試験部材に対して、以下の条件で抜去力試験を行った。
測定器 :オートグラフ
測定速度:5mm/sec
判定基準:200N以上
通電試験の概略を図7に示す。図7に示すように、試験部材17に鉄製のシャフトSを挿入し、そのシャフトSと試験部材17の内輪17aの外周面とに絶縁抵抗測定器20の各端子を当てて、以下の条件で絶縁抵抗値を測定した。各試験例において、3サンプルずつ測定を行い、その平均値を表1に示す。
