| Zusammenfassung: | The present invention generally relates to a shaft seal, and, more specifically, to a shaft seal that provides a high resistance to infiltration of contaminants from one side of the shaft seal to the other side of the shaft seal.
A multiple shaft seal arrangement positioned between a shaft and an inside diameter surface of an aperture in a wall. The multiple shaft seal arrangement has a flinger attached to the shaft with a face seal mounted to the flinger. A double lip oil seal is mounted to the inside diameter of the aperture. The flinger is positioned such that the face seal is pressed against the double lip oil seal. Accordingly, rotation of the shaft causes rotation of the flinger and face seal. This centrifugally throws contaminants, such as particulate matter, away from the aperture. The void between the face seal and the inside diameter of the aperture is filled with grease or similar substance. The combination of these elements greatly prohibits debris, moisture, particulate matter or other environmental elements from passing from one side of the multiple shaft seal arrangement to the other. |
