ABSTRACT:
A compression journal for transfer of microwave signals across a rotating interface of a rotary joint comprises a silver impregnated graphite split ring stator which surrounds and is in contact with a coin silver sleeve of a shaft rotor when a rotor assembly is positioned within a stator assembly. At least one O-ring is placed over the outside of the split ring stator to allow slight compression of the silver/graphite split ring stator to maintain continuous electrical contact between the stator and the rotor. A beryllium-copper radial shield is secured to the end of the compression journal securing it within a cavity of the stator assembly. The compression journal floats within the stator assembly to allow rotor/stator concentricities to adjust and seat properly for long term performance.
