The transfer apparatus is directed toward electrical transfer components providing an electrical connection to a rotating object. The transfer apparatus includes a stator base mounted proximate to the rotating object. An axle rotatably mounts at least one conductive disk to the stator base. The conductive disk is held against the rotating object. As the rotating object rotates about a first axis, the conductive disk is made to rotate about a second axis, the second axis otherwise maintaining a static position. A rotationally immobile contact is maintained in substantial electronic contact with the conductive disk whereby a lead wire may be connected to the immobile contact.

Rotating electrical transfer components

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.
