ABSTRACT:
An electrical conductor arrangement is provided for the conducting of electrical currents from a rotating shaft to a non-rotating conductor. The arrangement provides for an electrically conductive worm with helical grooves affixed to the shaft so as to rotate therewith and a flexuous electrical contactor disc, formed by a plurality of flexible electrically conductive fibers projecting radially from a central annular hub, which is rotatably mounted such that the fiber surfaces adjacent to the ends of the conductive fibers engage the walls of the helical grooves of the worm. As the shaft and worm rotate, successive ones of the electrically conductive fibers contact and move with the worm helix causing the flexuous electrical contactor disc to rotate at a reduced speed determined by the radius of the disc and the number of grooves of the worm helix. The rotatable mounting for the flexuous electrical contactor includes a flexible conductive annular race which cooperates with intermediate electrically conductive ball bearings and a further race in the central hub of the conductive disc. The non-rotating conductor is a wire conductor attached to the flexible conductive annular race.
In a preferred embodiment, the axis of the flexuous electrical contactor disc is mounted at an oblique angle to a plane perpendicular to the axis of the worm.
