浮动油封适用于工程机械的行走部件与行星减速部件上端面的动态密封,属机械密封,一般由铁合金材料的浮封环及配套的丁腈橡胶O形密封圈组成。浮封环需成对使用,一个随旋转件转动,一个相对静止。浮动油封的密封原理是2个浮封环靠O形密封圈受轴向压缩后变形产生浮封环密封端面压紧 Floating seal is suitable for the dynamic sealing of the traveling parts of the construction machinery and the upper end surface of the planetary deceleration parts. It is a mechanical seal and is generally composed of the floating seal ring made of ferrous alloy and the matched nitrile rubber O-ring. Floating seal ring to be used in pairs, one with the rotating member rotation, a relatively static. Floating seal the principle of sealing is 2 floating ring by O-ring by the axial compression after the deformation of floating ring sealing surface compression
