Beschreibung
Zusammenfassung:	The utility model relates to the technical field of sealing, and discloses a sealing structure for a shaft, which comprises a base fixedly sleeved on the shaft, a sealing inner sleeve sleeved on the shaft and capable of sealing between the sealing inner sleeve and the shaft through self deformation, and a sealing outer ring sleeved on the outer side of the sealing inner sleeve and forming conical surface fit with the sealing inner sleeve, the sealing inner sleeve is provided with an outer conical surface used for conical surface fit, the sealing outer ring is provided with an inner conical surface used for conical surface fit, and the end face, close to the small-diameter end of the inner conical surface, of the sealing outer ring is a sealing plane perpendicular to the axis of the sealing outer ring. The sealing plane axially and outwards exceeds the end face, close to the small-diameter end of the outer circular conical surface, of the sealing inner sleeve or is flush with the end face, close to the small-d
