Pin shaft sealing structure and excavator
The invention discloses a pin shaft sealing structure and an excavator and relates to the technical field of mechanical sealing. The pin shaft sealing structure comprises a pin shaft, a shaft sleeve,a sealing cutting sleeve and a first lip-type sealing ring. The shaft sleeve and the sealing cutting sleeve are arranged on the shaft pin in a sleeving mode and are in clearance fit with the shaft pin, the two ends, close to each other, of the shaft sleeve and the sealing cutting sleeve are in labyrinth sealing, an annular installation groove is formed in the inner side wall of the sealing cuttingring in a concave mode in the radial direction, and the first lip-type sealing ring is embedded in the annular installation groove and is attached and held to the outer side wall of the pin shaft inan abutting mode. The pin shaft sealing structure has a better sealing effect, and thus the working reliability of the pin shaft is ensured.
本发明公开了一种销轴密封结构及挖掘机，涉及机械密封技术领域。该销轴密封结构包括销轴、轴套、密封卡套及第一唇形密封圈，轴套与密封卡套均套设于销轴上并与销轴间隙配合，轴套与密封卡套相互靠近的两端迷宫式密封，密封卡套的内侧壁上径向凹设有安装环槽，第一唇形密封圈嵌设于安装环槽内，并与销轴的外侧壁贴合并抵持。本发明提供的销轴密封结构具有更好的密封效果，进而保证了销轴工作的可靠性。
