The invention discloses a lubricating type sealing assembly structure for a tail shaft. The lubricating type sealing assembly structure comprises an outer ring sleeve, a tail shaft body, a positioning ring body, a position adjusting assembly and a sealing ring body. The outer side of the periphery of the tail shaft body is supported and positioned through the two positioning ring bodies, the supporting contact area of the interior of the outer ring sleeve and the tail shaft body is reduced, the abrasion surface is reduced, lubricating oil is injected through the oil passing groove, and the inner side of the periphery of the positioning ring bodies tightly abuts against the outer side face of the tail shaft body; therefore, lubricating oil is difficult to permeate between the contact ring surfaces of the positioning ring body and the tail shaft body, so that a plurality of flow guide openings are uniformly formed in the periphery of the inner side of the positioning ring body, and the lubricating oil can be in contact with the side surfaces of the tail shaft body positioned on the inner sides of the flow guide openings through the flow guide openings; and the side face, making contact with lubricating oil, of the tail shaft body rotates to the periphery of the inner side of the positioning ring body, so that the lubricating oil permeates between the inner side of the positioning ring body and the tail shaft body, and abrasion is greatly reduced.

    本发明公开了一种艉轴润滑式密封装配结构,包括外部环套、艉轴本体、定位环体、位置调节组件、密封环体;本发明通过两个定位环体对艉轴本体的四周外侧进行支撑定位,降低了外部环套内部与艉轴本体的支撑接触面积,降低磨损面,通过通油槽注入润滑油,由于定位环体四周内侧和艉轴本体的外侧面紧密抵接,如此使得定位环体和艉轴本体接触环面之间润滑油难以渗透,为此本发明在定位环体的内侧四周均匀开设多个导流口,如此润滑油可以通过导流口与位于导流口内侧的艉轴本体侧面接触,而当艉轴本体进行转动时,就使得接触了润滑油的艉轴本体侧面转动至定位环体的内侧四周,如此使得定位环体的内侧与艉轴本体之间渗透入润滑油,极大的降低了磨损。
