Description
まず、図3(a)に示すように、比較的小径に形成した加締め前の密封板(シールド)2の基端(外径)2eを係止溝6gの内側に位置付ける。この場合、密封板(シールド)2の基端(外径)2eには、その外周縁を周方向に沿って等間隔に一部切り欠いて形成した複数の切欠部2kと、切欠部2k相互間に介在された複数の折返し部2pとが周方向に沿って交互に配列構成されている(図3(c),(e))。また、各々の切欠部2kは、その切欠奥端12tから外方に向けて末広がり形状(略V字形状)を成して構成されている(図3(d))。
なお、本実施の形態の密封板としては、上述した転がり軸受(図3(a),(b))に設けられる金属製のシールドを想定する。この場合、転がり軸受の構成は図3(a),(b)と同様であるためその説明は省略し、以下、密封板(シールド)についての説明にとどめる。
2e 基端
2f 先端
2k 切欠部
2p 折返し部
12t 切欠奥端
Claims (4)
- 転がり軸受の軌道輪間に設けられ、潤滑剤の漏洩防止と共に異物の浸入防止を図る環状の密封板であって、
密封板は、その基端が一方の軌道輪に装着可能であり、当該基端を一方の軌道輪に装着した状態において、その先端が他方の軌道輪に向けて延出していると共に、
当該密封板の基端には、その周縁を周方向に沿って所定間隔に一部切り欠いて形成した複数の切欠部と、切欠部相互間に介在された複数の折返し部とが周方向に沿って交互に配列構成されており、複数の切欠部は、その切欠奥端から外方に向けて先細り形状を成して構成されていることを特徴とする密封板。 - 切欠部の総数Nは、転がり軸受に組み込まれる転動体の総数をZとすると、
N≧nZ±X(nは正の整数、Xは2以上の整数)
なる関係を満足するように設定されていることを特徴とする請求項1に記載の密封板。 - 密封板の基端は、中空の金属製円板の周縁を周方向に沿って所定間隔に一部切り欠いて複数の切欠部を形成した後、各切欠部相互間に残留した部位を同一方向に折り返し、これにより複数の折返し部を形成することで構成されていることを特徴とする請求項1又は2に記載の密封板。
- 請求項1〜3のいずれかに記載の密封板を有する転がり軸受であって、
互いに相対回転可能に対向配置された軌道輪と、軌道輪の対向面間に転動自在に組み込まれた複数の転動体とを備えていると共に、一方の軌道輪の対向面には、密封板の基端が装着される係止溝が形成されていることを特徴とする転がり軸受。
