Floating oil seal

The invention discloses a floating oil seal. The floating oil seal comprises a pair of floating seats attached to each other and a pair of sealing rings attached to each other and installed in the corresponding floating seats, and the inner side faces of the floating seats are structurally and correspondingly matched with the outer side faces of the sealing rings. The inner side surface of each floating seat consists of a taper surface and a cylindrical surface; taper grooves are formed in the taper surfaces, and Y-shaped sealing rings are embedded in the taper grooves; and annular grooves areformed in the cylindrical surfaces, and O-shaped sealing rings are embedded in the annular grooves. The floating oil seal is compact in structure, reliable in sealing, capable of greatly improving the sealing performance and stable and reliable in work. 本发明公开了一种浮动油封，包括一对相互贴合的浮动座和一对相互贴合安装在对应浮动座内的密封环，所述浮动座的内侧面与密封环的外侧面在结构上对应匹配；浮动座的内侧面由锥度面和圆柱面组成；在锥度面上开设有锥度凹槽，并在锥度凹槽中嵌装有Y型密封圈；在圆柱面上开设有环形凹槽，在环形凹槽中嵌装有O型密封圈；本发明结构紧凑、密封可靠并且其密封性能得到大幅
