ABSTRACT:
A seal assembly is provided for preventing excessive movement between two housings. Whenever two rotating shafts are coupled together, one shaft driving the other, there is generally some movement of the shafts and their respective machines relative to each other. It is preferable to cover the rotating shafts for safety and to provide lubrication. A flexible membrane is attached between a coupling guard adapter which is rigidly mounted to the housing of one piece of equipment, and a back-up ring. This assembly is then attached to a coupling guard which is itself rigidly mounted to a housing on the other piece of equipment. Finally, a membrane guard is attached to the coupling guard.
