Description
以下、本発明の一実施形態に係る半割軸受10について図を参照しながら説明する。図1は、本発明の一実施形態に係る半割軸受10の平面図であり、図2は、図1のA−A線断面図である。また、図3は、図1のB−B線断面図である。図面においては、半割軸受10の外周面の中心(中心軸)を原点とし、半割軸受10の合せ面の内周面側の端と原点とを結ぶ線を始線とし、すべり軸受が支持する軸の中心軸(内周面の軸方向)の方向をz軸とする極座標を用いて説明する。なお、座標系において、図2の紙面手前側から奥側に向かい、z成分が増加する方向を+z方向とし、反対にz成分が減少する方向を−z方向と定義する。
以上、本発明の実施形態について説明したが、本発明は上述した実施形態に限定されることなく、他の様々な形態で実施可能である。例えば、上述の実施形態を以下のように変形して本発明を実施してもよい。なお、上述した実施形態および以下の変形例は、各々を組み合わせてもよい。
