CABLE TRANSITION BETWEEN INTER-SWIVELLING PARTS OF MACHINE (VERSIONS) Russian patent published in 2012 - IPC H02G11/00 

FIELD: electricity.

SUBSTANCE: as per the first version, cable transition contains cable harness arranged in separating rings designed composite. One of rings is connected kinematically to both parts of machine and is movable. Outside the harness there located is cam mechanism, movable separating ring is connected kinematically to both parts of machine by guide bearing and by roller from the other side which is fixed on movable separating ring entering a groove of cylinder cam. Cam profile is designed as right and left half-turn on outer side of cylinder inside which cable harness is located. As per the second version, cable transition contains cable harness arranged in separating rings designed composite. One of rings is connected kinematically to both parts of machine and is movable. Cam mechanism is located outside the harness. Movable separating ring is connected kinematically to one of parts of machine by guide bearing and by roller from the other side, which is fixed on movable separating ring entering a groove of cylinder cam. Cam profile is designed as right and left half-turn on outer side of cylinder inside which cable harness is located. In fixed separating ring a tube is fixed which is installed inside cable harness, and inside the tube there located is an additional cable harness in the form of multifillar helix which ends are fixed on separating rings.

EFFECT: improving reliability of cable transition and simplifying its design both with increasing cyclic strength of cable harness.
