Coupling guard seal assembly

摘要

A coupling between two shafts surrounded by a coupling guard seal assembly to prevent the leakage of fluid from out of the coupling. The coupling guard includes two coaxial closed overlapping surfaces otherwise described as inner and outer cylinders. The inner surface is formed with a groove which contains an annular gasket and notched ring. The outer surface includes circumferentially spaced apart slots which when aligned with the notches provide key ways for cam pins. When assembled the cam pins are each locked against the notched ring causing the "O" ring to elongate in the radial direction to provide an improved seal.
