Description
この特異的な剥離は、通常の金属疲労により生じる転走面内部からの剥離と異なり、転走面表面の比較的浅いところから生じる破壊現象で、水素が原因の水素脆性と考えられている。
このような早期に発生する白色組織変化を伴った特異な剥離現象を防ぐ方法として、例えばグリース組成物に不動態化剤を添加する方法が知られている(特許文献1)。
しかしながら、近年の転がり軸受の使用条件の過酷化に伴い、不動態化剤を添加する方法では充分な対策ができなくなってきている。
また、上記モリブデン酸金属塩がモリブデン酸ナトリウム、モリブデン酸カリウムおよびモリブデン酸リチウムから選ばれた少なくとも一つのモリブデン酸金属塩であることを特徴とする。
また、上記有機酸塩が炭素数 1 から炭素数 20 の有機酸のナトリウム塩であることを特徴とする。また、上記有機酸が安息香酸、セバシン酸、またはコハク酸であることを特徴とする。
各成分の配合割合は、グリース組成物全体に対して、上記モリブデン酸金属塩が 0.01 〜 5 重量%、該モリブデン酸金属塩の添加量に対して、上記有機酸塩が 5 〜 70 重量%配合されてなることを特徴とする。
また、上記増ちょう剤がウレア系増ちょう剤であることを特徴とする。
深溝玉軸受1は、外周面に内輪転走面2aを有する内輪2と内周面に外輪転走面3aを有する外輪3とが同心に配置され、内輪転走面2aと外輪転走面3aとの間に複数個の転動体4が配置される。この複数個の転動体4を保持する保持器5および外輪3等に固定されるシール部材6が内輪2および外輪3の軸方向両端開口部8a、8bにそれぞれ設けられている。少なくとも転動体4の周囲にグリース組成物7が封入される。
軸受部における摩擦摩耗面または摩耗により露出した鉄系金属新生面において反応して、酸化鉄とともにモリブデン化合物を含有する膜を形成しやすい金属としてはアルカリ金属であることから、本発明においては、モリブデン酸塩のアルカリ金属塩が好ましい。好適なアルカリ金属のモリブデン酸塩はモリブデン酸リチウム、モリブデン酸ナトリウムまたはモリブデン酸カリウムが挙げられ、これらは単独でも混合物としても使用できる。
基油にウレア化合物を配合して各種配合剤を配合するためのベースグリースが得られる。ベースグリースは、基油中でイソシアネート化合物とアミン化合物とを反応させて作製する。
表1および表2に示した基油の半量に、4,4−ジフェニルメタンジイソシアナート(MDI)を表1および表2に示す割合で溶解し、残りの半量の基油に4,4−ジフェニルメタンジイソシアナートの2倍当量となるモノアミンを溶解した。それぞれの配合割合および種類は表1および表2の通りである。
4,4−ジフェニルメタンジイソシアナートを溶解した溶液を撹拌しながらモノアミンを溶解した溶液を加えた後、100 〜 120 ℃で 30 分間撹拌を続けて反応させて、ジウレア化合物を基油中に生成させた。
これにモリブデン酸塩、有機酸塩および酸化防止剤を表1および表2に示す配合割合で加えてさらに 100 〜 120 ℃で 10 分間撹拌した。その後冷却し、三本ロールで均質化し、グリース組成物を得た。
酸化防止剤はアルキル化ジフェニルアミンを用いた。
モータ用転がり軸受(6204)に各実施例で得られたグリース組成物をそれぞれ 1.8 g 封入し、軸受外輪外径部温度 180 ℃、ラジアル荷重 67 N 、アキシャル荷重 67 N の下で、 10000 rpm の回転数で回転させ、焼きつきに至るまでの時間を測定した。
モータ用転がり軸受(6204)に各実施例で得られたグリース組成物をそれぞれ 1.8 g 封入し、負荷荷重をかけるために、電装補機の一例であるオルタネータの回転軸を支持する内輸回転の転がり軸受に組み込み、急加減速試験を行なった。急加減速試験条件は、回転軸先端に取り付けたプーリに対する負荷荷重を 3234 N 、回転速度は 0 〜 18000 rpm で運転条件を設定した。そして、軸受内に異常剥離が発生し、振動検出器の振動が設定値以上になって発電機が停止する時間を計測した。
表2に示した基油にLi−12−ヒドロキシステアレートを投入し、撹拌しながら 200 ℃にて加熱溶解した。なお、それぞれの配合割合は表2の通りである。その後冷却し、これに、モリブデン酸塩、有機酸塩および酸化防止剤を表2に示す配合割合で加えて、三本ロールで均質化し、グリース組成物を得た。このグリース組成物について、実施例1と同様に高温高速試験および急加減速試験を行なった。ただし、Li石鹸グリースの耐熱性を考え、高温高速試験は 150 ℃にて行なった。
実施例1に準じる方法で、表2に示す配合割合で、増ちょう剤、基油を選択してベースグリ一スを調整し、さらに添加剤を配合してグリース組成物を得た。得られたグリース組成物を実施例1と同様の試験を行なって評価した。結果を表2に示す。
