Claims (2)
- 歯車箱内に歯車減速機構を内蔵し、前記歯車箱内に前記歯車減速機構を潤滑する潤滑油を封入し、前記歯車減速機構を構成する回転軸からの前記潤滑油の漏洩をオイルシールによりシールする歯車減速機の軸封部構造において、
前記歯車減速機の軸封部構造は前記オイルシールと、前記潤滑油をろ過するフィルタと、前記回転軸の外周面に隙間を介して対向し前記潤滑油の圧力を低減する圧力低減部とから構成され、
前記圧力低減部が、前記オイルシールより前記歯車減速機構に近い側で前記歯車箱の延長部分と前記回転軸の外周面の円筒部分とが一定の間隙と長さ有して対向する潤滑油流路として形成され、
前記フィルタが、前記潤滑油流路として形成された圧力低減部に隣接して配置され、前記オイルシールと前記圧力低減部との間に位置して前記圧力低減部に接するとともに、前記回転軸の外周面の円筒部分に回転自在に密着するように設けられていることを特徴とする歯車減速機の軸封部構造。 - 前記フィルタが、前記オイルシール側の側面に補強板を有することを特徴とする請求項1記載の歯車減速機の軸封部構造。
