Description: |
| Claim:
In a shaft seal or the like for effecting a seal between a pair of relatively rotatable elements, an annular support element of flexible resilient material having first and second sleeve portions and an intermediate diaphragm portion interconnecting said sleeve portions, means for securing said second sleeve portion to one of the relatively rotatable elements, a seal ring of brittle lubricating material having a cylindrical outer surface and a sealing face arranged to co-act with a sealing face on the other of the relatively rotatable element to form a seal, and a rigid band having a cylindrical inner surface for pressing said first sleeve portion into engagement with said cylindrical outer surface of said seal ring, said first sleeve portion being compressed between said cylindrical inner and outer surfaces to an extent sufficient to frictionally hold said seal ring against axial movement, and said first sleeve portion and said seal ring having axially extending interlocked projection and recess means to prevent relative rotation thereof. |
