Radial shaft sealing ring |
摘要 |
A radial shaft sealing ring is disclosed. The sealing ring comprises a flat circular sealing element fabricated from a polymer material. The outer circumferential region of sealing element is mounted in a holding ring which surrounds the shaft. The sealing element is curved from the outer circumferential region to the inner circumference in the direction toward the sealed off medium with the sealing element being expanded away from the shaft in the region adjacent the inner circumference. The sealing element contacts the shaft intermediate the outer circumferential region and the expanded inner circumference region thereby providing a circular sealing contact area. The sealing element curvature provides an increasing inside diameter for the sealing element along the axial distance of the shaft from the circular sealing contact area to the expanded inner circumference. The inner circumferential area may be provided with swirl fins.
