Description

【発明の詳細な説明】 (産業上の利用分野) この発明はころかり軸受のためのプラスチック保持器に
関する。
(従来の技術及び問題点) 多くのころがり軸受にあっては、軸受内にて複数の転動
体を互いに離れた状態に維持するために保持器は必須の
ものである。一般に、軸受の保持器は一体形の環状体に
種々の方法で転動体の保持のための開口か形成されてい
るか、あるいは互いに周面で間隔をもつ二つの環状体を
組み合せたときに開口が転動体を保持するように構成さ
れている。環状体の周面は必ずしも円筒形状をなしてい
るものばかりではなく、軸方向に円錐状をなしているも
のもある。
保持器の材質に関して3えば、物理特性そして製造容易
性等の点て優れているプラスチックのものも多く作られ
ている。
しかし、これらのプラスチック保持器ては、製造時及び
運転時において予め十分なる注意をはらっているにも拘
らず、比較的短期間の運転後ても欠陥か生じてしまうと
いう問題点かあることか知られている。
L記問題点は、保持器をなす比較的軟らかい材料の中に
比較的硬い異物か混在し、転動体との摩擦の際に上記異
物か削り取られて出てきてしまうということに起因する
ことか判明した。
すなわち、L記入物は潤滑剤等を介して軸受内部に進入
し、転動体を傷つけてしまい、その結果軸受の使用不可
能な時期の到来を早めてしまうのである。
(問題点を解決するための手段、作用及び効果)本発明
は、上述の問題点を解決するために、プラスチック保持
器がその表面に少なくとも部分的に比較的硬い金属層を
有しているようにすることにより構成され、該金属層は
保持器の表面に好ましくはイオン放電(ionic d
ischarge)もしくはイオンインプレイティング
(ionimplantation)によって形成され
る。
L記金属層は窒化クロムを含むことか好ましい。その理
由は、放電中湿度は比較的低いのて、かかる低温ならば
プラスチック保持器か十分に耐え得るからである。
かくして、保持器表面が硬い金属層で覆われているため
に、転動体との摩擦によっても、内部の異物か出てくる
ことかなく、円滑な運転が持続てきる。
