Abstract
A rotary cable treatment assembly for use on cables having a non-circular cross section formed from a stator that housing a rotor formed from two hydraulically sealing bearings. A cable having a non-circular cross section is passed through the assembly wherein a lubricant or high viscosity inhibitor is pressurized to about 3000 psi within the assembly causing the fluid to coat all internal strands that form the cable. The rotor and hydraulically sealing bearings rotate according to the helix of the cable to reduce or eliminate wear on the cable and sealing.
Claims20
A rotary cable treatment assembly comprising:
- a stator formed from a first generally semi-cylindrical shell having an inner surface and an outer surface with a proximate endwall located along a first end of said shell and a distal endwall located along a second end of said shell, a second generally semi-cylindrical shell having an inner surface and outer surface having both proximal and distal endwalls forming a mirror image of said endwalls of said first shell, said first shell being securable to said second shell thereby defining a cavity therebetween with each said endwall cooperating to form an aperture adapted to encircle a cable traveling axially through said stator;
- a rotor assembly rotatably secured within said cavity, said rotor assembly having a centrally located aperture designed and arranged to fit around the cable traveling axially through said stator, said rotor assembly including a means for hydraulically sealing to said stator and to the cable;
- a high pressure fluid input port;
- wherein a cable is passed between the proximal and distal apertures of said stator and said rotor whereby the cable may be subjected to a high pressure fluid allowing fluid impregnation to cable strands with minimal fluid loss from said assembly wherein said first and second shell includes a sealing ring therebetween.

A rotary cable lubricant treatment assembly for use on cables having a non-circular cross section, said assembly comprising:
- a stator formed from a first generally semi-cylindrical shell having an inner surface and an outer surface with a proximate endwall located along a first end of said shell and a distal endwall located along a second end of said shell, a second generally semi-cylindrical shell having an inner surface and outer surface having both proximal and distal endwalls forming a mirror image of said endwalls of said first shell, said first shell being securable to said second shell thereby defining a cavity therebetween with each said endwall cooperating to form an aperture adapted to encircle a cable having a non-circular cross section traveling axially through said stator, said first shell is hingedly coupled to said second shell and securable in a closed position by at least one fastener;
- a rotor rotatably secured within said cavity, said rotor having a centrally located aperture designed and arranged to fit around the cable traveling axially through said stator, said stator including a tab located around the inner surface at a predetermined distance from said stator proximal and distal endwalls, said rotor including a first seal located between said proximal endwall and one end of said rotor, and a second seal located between said distal endwall and a second end of said rotor, each seal having an outer surface conforming to the inner surface of said stator and an inner surface conforming to the outer surface of the cable, each said seal having a detent located around the circumference of each seal;
- a bearing and rotating bushing means for maintaining said rotor in a predetermined position from the inner surface of the stator;
- a high pressure lubricant input port;
- wherein a cable having a non-circular cross section is passed between the proximal and distal apertures of said stator and said rotor whereby the cable is subjected to said high pressure lubricant allowing lubricant attachment to cable strands with minimal lubricant loss from said assembly.
