船用舵杆双面唇形密封圈

本发明涉及一种船用舵杆双面唇形密封圈，包括密封圈本体，密封圈本体的上、下两端分别同轴背向对称向外侧倾斜延伸一体制有上内侧唇口、上外侧唇口和下内侧唇口、下外侧唇口，所述上内侧唇口和上外侧唇口唇口密封端所在的密封面垂直于密封圈内孔；所述下内侧唇口和下外侧唇口唇口密封端所在的密封面垂直于密封圈内孔；从而形成了双面端面密封结构；在上、下内侧唇口的顶部和底部位置靠近密封圈内孔一侧均一体制成斜台环面，在密封圈本体的周边橡胶中间制有不锈钢加强芯环，斜台环面内均制有聚四氟密封圈。本发明采用双面唇形密封结构，对舵杆密封效果好、振动敏感度小、舵杆表面磨损少。 The invention relates to a marine rudderstock double-sided lip seal ring which comprises a seal ring body. An upper inner side lip and an upper outer side lip as well as a lower inner side lip and a lower outer side lip are integrally arranged at the upper end and the lower end of the seal ring body in a coaxial opposite-symmetrical outwards-inclined extending way; a sealing surface on which the lip sealing end between the upper inner side lip and the upper outer side lip is located is perpendicular to a seal ring inner hole, and a sealing surface on which the lip sealing end between the lowerinner side lip and the lower outer side lip is located is perpendicular to the seal ring inner hole, so that a double-sided end surface sealing structu
