Description
[1] 外輪と、
内輪と、
前記外輪および前記内輪の間に組み込まれた複数の転動体を、円周方向に等間隔に設けられた複数のポケットでそれぞれ保持する保持器と、
を備える転がり軸受であって、
軸受内部に潤滑油が流入する油潤滑で使用され、
前記保持器の内周面に潤滑油を溜めるための切り欠き部が形成され、
前記切り欠き部の径方向寸法h、前記外輪の内径寸法D1、前記保持器の外径寸法D2、軸受ピッチ円直径dm、前記転動体の数z、前記転動体の外径寸法Da、前記転動体の軸方向寸法Lにより式(1)で表される軸受内部寸法比αが、1.4≦α≦2.1を満たすことを特徴とする転がり軸受。
以下、図面を用いて、本発明の転がり軸受の第1実施形態について説明する。図1は、本発明の第1実施形態に係る転がり軸受100の断面図であり、図2は転がり軸受100の側面図、図3は転がり軸受100の保持器10の斜視図、図4は転がり軸受100内部での潤滑油の循環を説明するための図である。
図7に示す試験構造を用い、シャフトSに転がり軸受100を組み込んで、回転試験を実施した。回転試験は、転がり軸受100の軸受内部寸法比αを変更すると共に、2つの回転数n、mを用いて行なった。図8はこの回転試験の結果を示すグラフであり、軸受内部寸法比αと、転がり軸受100内の温度低減効果との関係を示す。図8より、回転数をn、mと変更しても、軸受内部寸法比αが1.4≦α≦2.1を満足しているときに、十分な温度低減効果が得られることがわかる。
図10、11は第1実施形態の変形例に係る転がり軸受100’および転がり軸受100’に使用される保持器10’を示す。この保持器10’においても、内周面に矩形断面を有するよう切り欠き部15が形成されているが、保持器10’の軸方向両端部、すなわち円環部11、12の外周面には、外輪1のつば3に対応して切り欠かれた環状切り欠き部16、17が形成されている。保持器10’の外周面がこのような形状であっても、軸受内部寸法比αが上記した関係を満たす限り、温度低減効果を得ることができる。
次に、本発明の第2実施形態に係る転がり軸受について、図12、13を参照して説明する。第1実施形態と同一又は同等部分には同一符号又は相当符号を付して説明を簡略化又は省略する。
次に、本発明の第2実施形態に係る転がり軸受について、図14、15を参照して説明する。第1実施形態と同一又は同等部分には同一符号又は相当符号を付して説明を簡略化又は省略する。
