Beschreibung
Zusammenfassung:	The invention discloses a sealing structure for shaft which includes a shaft and a clapboard, wherein a part of the shaft on one side of the clapboard is a spherical fillet, a sealing member which periphery is fixed on the clapboard is sleeved on the fillet, surface on the sealing member contacted to the fillet is conical surface, and middle of the sealing member is elastic. The sealing structure can effectively stop medium on one side of the fillet leaking to the other side of the fillet and is adapted for processing of powdery material and transmission machinery; conical surface of the sealing member and spherical surface of the fillet joint closely all the time by tension of elastic rubber to form seal. Characteristic of the sealing structure is that an amount of axial floating or radial flopping of the shaft are permitted and sealing of the shaft is credible during shaft operation.
