Description: |
| Abstract:
A face-type shaft seal having components including a spring urged seal ring selectively retained and removed from an open end casing by a key and slot arrangement including a t-shaped key on the inner surface of the outer peripheral wall of the casing and having a leg coacting with an axially extending peripheral slot in the seal ring which is slidable in the casing and projects through the open end of the casing. This leg holds the seal ring against rotation relative to the casing but accommodates full axial movement of the seal ring in the casing. The shaped key has a head adapted to be selectively received in the slot for removal of the seal ring through the open end of the casing or the head may be misaligned from the slot to overlie an end face of the seal ring for retaining the components in the casing. One or more key and slot combinations can be used. |
