Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to cables, and in particular to individual 7-C coated λ cables of either straight wire or wire.

In some cases, the cables IC and C (DL, L, elliptical, and supplied to the individual core wires), which were proposed ten times ago, have a nearly circular cross section. Such cable constructions have a number of drawbacks5.
Individual·'? Since the strands of the wires deform and rotate relative to each other, they are not particularly stable. It is impossible to predict the 7J or so that this will occur.

The performance of such cables cannot be accurately predicted. Additionally, since the strand-to-strand contact takes place in a non-contoured area, the strand-to-line pressure is higher, which, in conjunction with the fact that the strands are at +1 force relative to each other, results in wear of the strands.
, this wear is caused by the pulley turning over the pulley (i, l
If il 7:, ), the deflection of the cable increases as it counteracts the relative movement of the strands. First, the area of contact between the stranded wire knob and the pulley is limited and vibrations lead to high stresses. In fact, the stranded wire force of 0 is Only limited flexing of such cables is allowed. Couples of this type also have a limited transmission of loads between the strands.

According to a first aspect of the invention, the wire is formed by 19 or multiple layers of stranded wires held together by strands, said layers''!
Is it at least 1':) that each linear line of the layer has a nearly constant spatial phase 4L relationship in both the individual 7 of the plastic or rubber layer? Provide cables that are molded to suit the needs of the user.

The second method of the present invention is to manufacture a cable formed by one layer or multiple layers of t-wires stacked together. - This is the twist of misgovernment! tdaha inno-4'A$-1

The lines are the same! ζ both at L and within the cable], constant space curvature 47. [1] A method for manufacturing a multiple is provided, which comprises arranging the related layers so that they are separated from each other.
゜Embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Regarding the dimension j'' in Figure 1, the cable of the first embodiment is more #1

The c data is made of aromatic polyamide (the product is KFL, VA
It is formed from a spun yarn from a plastic yarn such as R'J'C). The strands are different 41'* to enhance load distribution.
It is also good to have different combinations of l-shiri and different quantities of h-ti-C.

All elements 11-f/koha 9: road element/to 1
1 can be antinode with a fluorocarbon or rubber iodine source before being formed into a stranded wire. This reduces the friction between the filaments and increases the load transfer between the filaments and the filaments. , the stranded wire 10 is a metal wire 1.・Yo U' /-4 Q Well, it doesn't have to be formed from a bundle. Alternatively, the strands 10 may be formed by several bundles of yarns or strands of synthetic phase material arranged parallel to each other (as shown in the figure).
'). The strands 10 formed in this way are bundled in order to keep them together by applying a force (force C contraction I) to the extruded horn bar (I' L -r).

You can stay there.

After the stranded wire 10 is formed, it is passed through an extrusion die 12 (second jth threshold). A suitable molten metal or rubber material is heated and then pressurized from the material.

The die 12 has a generally trapezoidal shape with straight convergent sides 13 joined at its narrow end by a short convex end face 14 and at its wide end by a concave arcuate end face 151y. , the dimensions of the die are such that the die has a larger area than the cross section of the stranded wire 10, and the stranded wire 10 is attached to the die such that there is a gap between the outer surface of the stranded wire and the surface forming the die. (See Figure 2)
i1+111 drunkenness 13 convergence and bow 11 ends 1 river 14.
The 15 melodies are selected based on the ideas described in Section 3.

The stranded wire is supplied to the die at a predetermined supply line speed 11i.

At the same time, the die 12 rotates at a constant rotational speed IW, Qi, in a direction of rotation that is the same as the direction of the strands, but is compatible with the layers of the cable. .

As a result, a sheath 20 having a shape corresponding to the shape of the die is extruded from the stranded wire, and the sheath 20 extends in a spiral shape with one opening in the stranded wire. This is shown clearly in FIGS. 6 and 4, from which it can be seen that the sheath 20 is shown in *I; the IE side surface 16, the narrow concave end surface 17;
4 = Yohi wide (Convex fIriA) It is recognized that it has 18.j) III The 1∙ corner of the 1st side is selected as described below.

The extruded north 20 is connected to the element 11.

Soyohi J4! (dip into the gap between the wires) and use it to prevent sheathing. However, this relationship can be increased by creating a gap between the elements so that the center line is sunken deeply and can be removed. Alternatively, Id 1=lIadditional 1-i=, by chemically bonding i';'I to the wire before extrusion.
, 1 can form a bond between the sheath on the strand 1, and 7- before applying the sheath 20', during the strand'.
It is possible to insert size 4, 4, 4, and 4, according to 'C 1.
After pushing out the sheath, the slide H should be held within the sheath CX and the line for one moment.

As best seen in Figure 4, the rotation of the die 12 causes the sheath strands to come together! Extrude the two pieces into an I-J-shape. Since the supply linear speed of the stranded wire j11- and the rotational speed of the stranded wire are controlled, these bits can be arranged so as to have the required pitch. The method for determining the essential pinch is detailed in -1.4'.

The seeded stranded wire is then layered to form a rubble. In FIG. nail the line). However, any suitable cable construction can be used, but advantageously the wires have such dimensions, number and geometry as to allow the introduction of the tank, and are therefore connected in long lengths. I can ride it. As shown by the dashed lines in Figure 5, for example 2.'') more lines than the beads can be provided.

For each strand 22, the angle of convergence of the side surface 16 is concealed.

The selection is made depending on the diameter of the pull and the diameter of the core wire. However, it is recognized that if the 4III and 16 of the sheath 20 converge to a point, it is not necessary to include the core wire 21.

4) In order to identify the twist of the coupe, if the strand 10e is used, the return rise in the keratin and the pressing force 01, 1/c is the lead twist. It is desirable to heat cure the source after applying it.

The sides 16 of the one-wall abutment in the pile are opposed and engaged. In addition, the strands' strands form a continuous 'shaped external surface' for the cable9, and this construction offers a number of advantages, one of which is that the strands provide a space between all the strands. Since the reciprocal relationship is fixed by the sheath, it has a suitable geometry so that the strands are virtually immovable relative to each other and their placement within the cable is I can't change it. It is ° [, Kuichi -pulling performance (1 samurai (bow, stable, stable, can be predicted. This increases the life of the strands and therefore the life of the cable.

6. As a result of this, the stranded wire is able to move a little more easily than the phase L, and the cable is thus able to bend easily around the wire, and due to such bending, No.1 - Feel the bow) The increase in force decreases between 1 and 1.

4. The cylindrical outer surface has a couple and, for example, one driving sea,
This provides a large surface area for frictional engagement between the cables, thereby reducing the transmission of torque from the drive cooler to the cable, thereby reducing the single core force generated in the cables due to the cliff.

5. The outer surface of the cylindrical surface or the bearing surface of the support pulley may be increased or decreased, or the bearing pressure between such surface and the cable may be reduced, or the pulley load may be larger for the same bearing pressure. Due to this advantage, this V-section girdle is often used together with the \N11j]ni pulley, but this V-section girdle This means that the number of strands of such a couple is V-massed and the number of strands is
- The use of high bearing pressures with a tendency to sag - 4'' is not possible.

6. Because of the substantially solid Illus 11 bar 1 of the cable,
It is difficult to get inside the dust and other dangers.

Z1 solid stranded wire is not northed, but the entire outer surface of the cable or sheath ((more sheathed)) compared to the cable 7. It is.

8 Furthermore, compared to such cables, the failure of 19 of the 7-s of the iron or the corrosion of all the stranded wires will occur (7).

9 All strands (including core wires) 0 phase 1 (-
The engagement increases the load between the strands, so that the load is transferred evenly between the strands.

There are many variations to the arrangement described above6, among which are the following:

In this way, the strands 1 (la, 10b) of the layer are locked in the same way as the strands 10 in the embodiment of FIGS. 1-5. The outer surface 18b of the intermediate strand 101 is A cable is provided having an elongated arcuate length covering adjacent strands 10a and having a cylindrical outer surface.

In addition, between the Ktk I' and surface 16, a low friction material such as polytetrafluoroethylene is used.

Active locking between the cable and the cable is allowed.

Adjacent stranded wire layers or stranded wire layers may be in opposite directions to reduce rotation.

Furthermore, each strand 35, 36 is itself surrounded by a wire of the type described with respect to FIGS. 1-4. The six outer L wires 36 have a straight line 40a turned into a curved surface 4 of 4+111 on the inner side.

Satisfying these two requirements) actually facilitates the connection. The reason for this is that the outer layer 38 can be easily peeled off from the stranded wire and the stranded wire can be easily separated.

It is desirable that the coupling is arranged in such a way that the coupling has the advantage of directing the material to weakening or first-time damage such as shrinkage. . Cables can be arranged in various ways, some of which are listed in the 1F section according to the examples, and can be used individually or in any suitable combination. The outer sheath 38 can be provided with a color that contrasts with the color of the sheathing 40 of the stranded wire 35,36. Yota (

If you set up a /J soto of the ifl and - series, J: Z' will detect J-lo, and cut ID: re-pull? 1) The two-C intervals are arranged in a slanted manner, and the length of each couple (with a known length υ′) extends) is a stranded wire. The contrasting color of the coating 40 is shown (3/located in the temple)1. Therefore, if there is a local reduction in the cable wall diameter, there is a tendency to close the cut, which is clearly indicated by the contrasting color of the sheathing 40 becoming indistinguishable.

The increase in length of the cable can be dictated by a series of short cuts (cuts), these cuts are distributed along the cable, and each horn is cut along its circumference. The distance has been extended.

These cuts are generally arranged so that they are not visible, or they open up in the case of an increase in the length of the cable so that the contrasting color of the stranded wire sheathing 40 appears. I will briefly explain how to do this.

First, the aromatic polyamide fibers constituting the rope may be in the form of yarns, each yarn comprising a number of, for example one
Consisting of 5000 nouraments.

Therefore, the first step in the process, at 1° C., is the twisting operation to convert the yarn into a cord. Each cord 3r may consist of only one yarn, or it may consist of more than one yarn, even 6, 5 or 7 yarns. Even if each cord 37 consists of only one -V-n, the twisting operation still takes place. ''Before the operation, it is possible to carry out an operation to apply the yarn to the binder.

Next, create strands 35 and 36 from the cord 37.1.
Each strand 35.36 id, a relatively large number of 2 J-dos 37,
For example, from the code 60.~2[]O, it is 1. Within each ascending line 35.36, the needles 37 are all parallel to the car and are: Ino surrounding the I-does 37, only the neck is similar 41 half-jjc [Δt it, -U is .

The wires are fed at right angles, surrounding the cords j7f, 8-g/z to hold them all together. This method therefore forms the outer cover 40. The stranded wire exiting the extruder then enters a continuous heating chamber in which rubber is added.

The seven strands thus formed are then strung together and layered together to form a cable according to the method shown in the drawings. Next, add 38 pieces of outside sauce at 0°C using extrusion technique.

Finally, heat and pressure are applied to the cables to join the five bodies together. For this purpose, a hydraulic press can be used, which presses one course of a young 1° run.
It is large enough to process multiple files at once.

In one embodiment, the cord is within each strand -'C---

As described in FIG. Moreover, between the part and the cable, the force is transmitted between 11 points (f, this 1φ).

In the present invention, 1.2) is an aromatic polyamide filament/this is a filament of 100% polyurethane. It is also possible to create examples - C) 3. For example, it is possible to use a copper wire; in this case, the steel wire is placed in the same way as the cord 37;

In the embodiment described above in conjunction with the drawings, the force moving inward at L is partially repulsed by 4.・Depending on the tension applied (1). It is therefore possible to obtain an indication of the rope tension, and thus a structure of slight tension, by using suitable means for determining the pressure exerted on the C1 centerline. (Kakai)
1. The upper blade can be used, for example, as an electric current (Naginorei 1゜4-).It is possible to use a synthetic monthly where the -!electricity changes sharply in response to the pressure, and therefore - The Kogako charge can be mixed in to see the pressure in the line from the center to 11□3.

During the cable, the length of the cable is too long? f), the wire a) can be installed to extend in the event of overstretching of the rope, and electrical monitoring of the rope elongation is thus necessary.

In all the embodiments of the invention described in conjunction with the drawings, the source is applied helically to the combined strands to allow for the laying of the strands into the cable. However, we do not find it necessary to use such a helical sheath. North can be applied to stranded wire in a straight configuration (no strands) and can be used when straightening the cable. In this case, if you do not fix the top layer, heat setting the sauce after layering will cause a problem.
