Definitions

  • the principal object of the present invention is to provide a new and improved construction-of a driving'means for a wire rope stranding machine by means of which the necessity for carryingthe large stock of gears is avoided and by means of which the speed ratio of capstan to spider may be accurately controlled and very slight variations or changes in such speed ratio may be made through the entire speed range of the driving gear.
  • a further object of the present invention is to provide a new and improved drive of the type set forth which, when adjusted for any desired speed ratio, will maintain such ratio with absolute accuracy and uniformity.
  • Another object is to provide a new and improved driving means for a wire rope'stranding machine that will be of marked simplicity, of compact and sturdy design and Frequently that will operate with certainty at all speeds 1 within the limits of the machine.
  • Fig. 1 is a plan view of an installation embodying the principles of the present invention
  • Fig. 2 is a side view thereof
  • Fig. 3 is a plan view of a modified form of installation
  • Fig. 4 is an enlarged view partly in elevation and partly in section of one of the elements of the hydraulic gear which forms a part of the present invention.
  • a speed reduction gearing such as indt cated by the reference character 16 being interposed between the motor and shaft 14.
  • the speed reduction gearing 16 has a shaftv 17 projecting laterally therefrom upon which shaft is secured a pinion 18 the latter meshing with and driving a gear 19 on the shaft 14.
  • the drum 20 is driven from a hydraulic motor 21 to which fluid under pressure is circulated from a fluid pressure 1 pump 22 by means of the pipe lines 23, 24.
  • the pump 22, or A-end as it is usually called, supplies the fluid under pressure to the motor, or B- shaft is actuated by means of a hand wheel 33 and any suitable means, such-for'ex ample as that shown in U. S. Patent No. 1,680,975 granted-August 14, 1928, is preferably provided for locking the hand wheel and control shaft in adjusted position so that the speed of the hydraulic gear and therefore the capstan speed can not be varied by any unau- I
  • the pump or A-end it will be noted is located, in the installation shown, immediately adjacent to, and is coupled to, the main driving means for the strandingmachine,
  • the pump 22 drives the capstan through a reduction gear of any suitable con-' struction wlnch gear is shown more or less diagrammatically in the drawings and is indicated by the, reference character 36.
  • a pinion 37 secured to a'projecting shaft of the gear box 36 drives a spur gear 38 mounted on a jack, or counter, shaft 39.
  • This shaft has secured to it a pinion 40 which meshes with a driving gear 41 secured to the shaft 42 of the capstan 20.
  • Both the A and Bends are of simiwith oil or other medium used as a pumping lar construction in that each comprises a rofluid, a reservoir 45 is located at a point tating barrel 25 having a plurality of cylinders 26 bored therein in parallelism with the reservoir communicates through the p pes 46 driving shaft 27 of the unit.
  • Each cylinder and 47, respectively, with the top points of has mounted forreciprocation therein a pisthe casings of the pump and motor.
  • the reston 28. and said pistons are reciprocated ervoir serves not only to insure that both the through the piston rods 29 by the medium of a swash plate- 30.
  • the swash plate 30 is mounted for rotation within a tilting box 31.
  • the tilting box In the motor or B-end the tilting box is usuall held at a fixed inclination while in the -end the angle of inclination of the tilting box may be varied by means of a control shaft 32.
  • the pistons 28 When the tilting box or the pump is at right angle to the driving shaft 27 thereof, the pistons 28 will have no stroke, no fluid will be delivered by the pump and the gear is said to be in neutral position.
  • the tilting box When, however, the tilting box is inclined to the shaft 21,,fluid will pump and motor, as well as the pipe lines 23, 24 will at all times be filled with fluid, but also serves to compensate for contraction and expansion of the fluid due to temperature changes. 1
  • the pipes 23,24 are preferably covered for a porhigher than any'point of the system and said tion of their length by water jackets 48, 49 I through which cooling water may be circulated.
  • the motor 27 will cause the capstan 20 to be rotated through the reduction gear 36, gears 37 38, jack shaft 39 and gears 40, 41.
  • the speed of rotation of'the capstan 20 and therefore the linear speed of travel of the completed wire rope which, it will'be understood, is drawn through the die 13 by the action of the capstan 20 may be varied as desired by adjusting the position of the control shaft 32 of the pump 22.
  • the pitch or lay of the strands can be controlled with mathematical accuracy as desired, because it is possible by slight changes of adjustment of the control shaft to secure very slight changes in the absolute speed of the capstan and therefore of its relative speed to the -spider 10.
  • the motor 15 may be of any suitable construction preferably designed to run substantially at a uniform speed.
  • Fig. 3 the invention is shown as carried out by the use of a type C Waterbury speed gear.
  • motor and pump units are constructed to form parts of an integral unit instead of being located at spaced points from each other in the manner shown in the installations of Figs. 1 and 2.
  • the wire rope stranding machine shown in Fig. 3 is identical in construction to that shown in Figs. 1 and 2.
  • the hydraulic speed gear consists of a motor 21' and a pump 22' mounted immediately adjacent to each other toform in effect an integral structure.
  • the pump is driven from the same driving shaft that drives the spider 10. Fluid from the pump is circulated to the motor through a dividing plate 61,-said plate being provided with suitable ports in accordance with the well known construction of hydraulic speed gears of the Waterbury type.
  • the driving shaft of the motor 21" is connected by means of a speed reduction gear 26', a pinion 10,
  • control shaft may be and a spur gear41 with thecapstan 20.
  • a spider driving means for rotating said spider, a control-die, a capstan drum for draw-' ing the stranded rope through said die, and means for rotating said capstan drum comprising a hydraulic gear consisting of a fluid pressure pump and a motor, driving connections between said pump and the spider driving means for'causing said pump to be driven 10( independently of the spider at a definite predetermined speed ratio relatively to said spider and driving connections between said capstan drum and said fluid pressure motor.
