摘要： An optical slip ring assembly couples an optic signal from a rotating source to a stationary detector. The rotor of the optical slip ring comprises rotor optic fibers each having a first end coupled with the optic signal source and a second light-emitting end which is aimed at the stator optic fibers. The stator optic fibers each have a first pickup end mounted in the stator block and are positioned in a radially symmetric array surrounding the rotor. An optic signal transmitted from the source through the rotor fiber is picked up by the stator fibers.

摘要： The present invention broadly provides improvements in a slip-ring adapted to provide electrical contact between a stator and a rotor. The improved slip-ring includes a brush assembly having a brush tube mounted on the stator and having a fiber bundle composed of a number of individual fibers. The upper marginal end portions of the fibers are received in the brush tube. The lower marginal end portions of the fibers extend beyond the brush tube toward the rotor. The improvements broadly comprise: a central portion of the fibers having been removed below the brush tube such that the fibers extending below the brush tube toward the rotor are in the form of an annulus; and wherein the tangential compliance of the fiber bundle at its point of contact with the rotor is more than twice the tangential compliance of the fiber bundle if the central portion had not been removed.

摘要： A method of manufacturing an annular base portion of an electrical slip ring assembly having a plurality of conductive rings formed in the outer circumferential surface thereof is described. The slip ring base is molded, and grooves are machined into the outer circumferential surface thereof. Conductive strips are cut into a series of lengths forming conductive rings to be placed about the outer circumference of the annular base member. The individual lengths of conductive material are anchored to the outer circumferential surface of the slip ring base and a rolling pressure is exerted on them about the circumference of the base to cause the rings to be press fit into the grooves previously formed on the base. When the complete circumference of the ring has been press fit into its respective groove, the other end of the conductive ring is then secured to the base. An appropriate fixture is provided for exerting the lateral and a rolling pressure on each conductive ring to properly press fit it into a groove on the annular base member.
