Definitions

  • Another object is to provide such a rope which has non-rotating characteristics.
  • FIGURE 1 is a perspective view of a 3 X 19 scale regular lay rope of our invention.
  • FIGURE 2 is an end view of a 6 x 19 seale regular lay wire rope.
  • reference numeral 1 indicates a wire rope consisting of three strands, each having a center core wire 4 surrounded by nine intermediate wires 6 and nine outer wires 8.
  • the strands 2 are formed in the usual manner except that the lay is shorter than that normally used.
  • the strands are formed, roll straightened and then stranded in a stranding machine where the strands are preferably partially preformed. We have found it advisable, and for most uses necessary, to stress relieve the formed rope. When the rope is made of steel, this is done at a temperature between 600 and 1150 F.
  • the lay of the strand in the rope is longer than that normally used and it is necessary that the angle of lay of the outer wires in each strand be at least 1% times that of the angle of lay of the strands in the rope. This is necessary in order that the torque exerted by the rope will be approximately equal to the torque exerted by the strands.
  • a rope so constructed is relatively non-rotating, with the amount of rotation being no greater than 3 per foot of length under loads of up to 75% of the breaking strength of the rope, and in many instances the amount of rotation is even as low as 1 per foot.
  • the angle of lay of the outer wires 8 is 21.8 and the angle of lay of the strands 2 is 10. For best results it is desirable that the relationship between the angles of lay be at least 2 to 1 rather than 1% to 1.
  • the rope of FIGURE 2 includes a core member 10 surrounded by six strands 12, each having a center wire 14, nine intermediate wires 16, and nine outer wires 18. Except for the lay of the wires in the strand and the lay of the strands in the rope, this rope is made in the usual manner. In other words, the strands are first formed and the strands then closed around the core 10. The strands are roll straightened and the rope stress relieved as in the first embodiment.
  • the relationship between the angle of lay of the outer wire in each strand and the angle of lay of the strand in the rope is preferably greater than in a three strand rope. In the six strand rope shown, the angle of lay of the outer wires 18 is 24.5 and the angle of lay of the strands in the rope is 7.
  • the strands may be of other constructions than those shown but will preferably be those constructions most commonly used.
  • the core shown in FIGURE 2 may be replaced by other types of cores, such as an independent wire rope core.
  • the relationships set forth above are necessary in order to obtain the desired characteristics.
  • the wires 6 and '8 are such that they tend to rotate in the direction of the arrows around the axis of wire 4, or in other words, under load they try to straighten out.
  • the strands 2 under load tend to untwist from one another in the direction of the arrows and these two torques counterbalance one another so that the wires and strands will not move out of position.
  • the wires 16 and 18 tend to rotate in the direction of the arrows and the strands 12 tend to untwist from one another in the direction of the arrows with the two torques counterbalancing each other.
  • a torque balanced regular lay rope comprising between three and six strands spiraled together, the angle of lay of the outer Wires in each strand being at least 1% times that of the angle of lay of the strands in the rope, the torque exerted by the rope being approximately equal to the torque exerted by the strands.
  • a torque balanced regular lay rope according to claim 1 in which the rope will rotate within 3 per ft. of length up to of the breaking strength.
  • a torque balanced regular lay rope according to claim 3 in which the rope will rotate within 3 per ft. of
  • a torque balanced regular lay rope according to claim 1 which consists of three strands spiraled together. 6.
  • a torque balanced regular lay rope according to claim 5 in which the rope will rotate within 3 per ft. of
  • a torque balanced regular lay rope according to claim 1 which consists of six strands spiraled together, the angle of lay of the outer wires in each strand being at least two times that of the angle of lay of the strands in the rope.
  • a torque balanced regular lay rope according to claim 8 in which the rope will rotate within 3 per ft. of length up to 75% of the breaking strength.
