Face Ring Retainer Arrangement For Mechanical Seal

US Patent:
5551708, Sep 3, 1996
Filed:
Jun 29, 1994
Appl. No.:
8/268235
Inventors:
John R. Vesey - Mattawan MI
Harry L. Mason - Portage MI
Assignee:
Durametallic Corporation - Kalamazoo MI
International Classification:
F16J 1538
US Classification:
277 81R
Abstract:
A mechanical seal assembly having a face ring disposed within an axially-opening recess associated with a support ring. The support ring includes a sleevelike shroud which externally surrounds and maintains the face ring in concentric relationship. A separate retainer ring cooperates between the shroud and face ring to axially and positionally secure the face ring to the support ring. The retainer ring includes an annular ring part which projects radially inwardly so as to radially overlap a part of the exposed face of the face ring to effect axial securement thereof to the support ring. The retainer ring in addition has an axially-extending sleeve part which projects axially and in surrounding relationship to the shroud. This sleeve part has a press-fit engagement with the shroud to create a fixed engagement of the retainer ring to the support ring.
