The invention relates to a wire rope from several wires, or strands, between which one Form-fitting connection producing and a smooth outer surface of the wire rope forming Füllsiüeke are provided.

In a known wire rope for winches or elevators, a © is a uniformly curved outer surface of the wire rope forming closure strips inserted between the strands. These have an I-shaped Cross-section and are helical in the longitudinal direction direction of the wire rope, arranged and so curved, that there is a strand inside, while one widened on each of the two outer surfaces Litz wire rests. Because the curved outer surfaces of the fastener strips are only part of the total surface of the wire rope form, the intermediate strands are only partially protected against wear. The wear strips must be incorporated at the same time as the wire rope is manufactured will and cannot be exchanged.,

In another known wire rope for lifting devices of the type mentioned are between the individual wires or strands in the longitudinal direction of the wire rope-running filler pieces are provided. These divide the. Wire rope cross-section in ikei equally large circular sectors and are on their outer circumference with circular. Equipped with recesses for the individual wires or strands. the Individual wires or strands lie loosely in the recesses the filling level. The filler pieces © should- a mutual touching of the individual wires © or strands prevent and reduce rope slippage on sheaves or drums. Keeping the Wire rope in the sense of a so-called locked Wire rope, is not possible with these filler pieces guaranteed.

Usually, for example for electrical cables or for suspension ropes: on suspension bridges or bicycles, locked wire ropes are used. They consist of a number of lying wires, which are covered by these helically surrounding wires · the one have profiled cross-section ,, se ^ that they with their contiguous; Surfaces a shutter; and make the wire rope a largely smooth one Lend outdoor space »

the strand emerges and thus indicates the break. This wire rope is because of the dei on its outer surface the helically wound »strands located no · a continuously smooth outer surface showing locked wire rope. "*

The closed wire ropes have the disadvantage that the profiled outer wires producing the closure have to be made of very tensile strength, costly steel to absorb the tensile forces and at the same time have a large surface area for exposure to the weather or when the wire rope is used as a support rope for a cable car; bid for their wear and tear. With the locked wire ropes used up to now, the profiled * wires for a tensile stress of 12Θ to 130 ^! kg / mm ² ), while with wires of round cross-section, which are made of a steel suitable for absorbing very high tensile forces, tensile forces of 20Ü to 210 ¹ kg / mm ² can be absorbed. As a result, a locked wire rope has a smaller cross section for a given cross section; Breaking tension than can be achieved with a simple wire rope of the same diameter, which consists of helically wound wires made of a steel of high tensile strength. In addition, long, heavy, locked wire ropes of the conventional design can often be “loaded and transported to your B & titamraigsoEt” by IHK · with great difficulty.

In this way, a plan view of the outer part and the arm for the staggered arrangement of the filler pieces is achieved, in which a non-positive connection with the wires or strands lying perpendicular to the longitudinal axis of the wire rope are designed accordingly. Staggered joints between the filler pieces

At the same time, this wire rope has a smoother 15, so that when the wire rope is used as the outer surface of the wire rope, the outer wires or strands of the carrying rope also have a round cross-section due to the relatively short cross-section and can, as the smooth running of the cable car rollers, join the inner wires or strands, from a steel According to the invention, the axial length of the arms can be made of high tensile strength. Since the filler pieces 2In the axial length of their outer wires, all of the wires have a round cross-section on part. The radial arms of the filler pieces can be compared to profiled ones then lie against one another when encompassing the core wire or wires with a significantly less technical core strand, so that they manufacture in the longitudinal effort, ie more economically. The pulling direction of the wire rope will form a closed unit of forces in the wire rope according to the invention.

To form a closed wire rope are between the core strand 1 and the surrounding Strands 2 on the one hand and a positive connection that can be used between these strands on the other hand filling pieces 3 producing and forming a smooth outer surface of the wire rope are provided.

The filler pieces 3 have, as shown in A b b. 2, an outer part 3 a forming a smooth outer surface of the wire rope and a radial arm 3 b reaching between two strands 2 and partially encompassing the core strand 1. The inner surface of the outer part 3 α and the arm 3 b are designed to produce a non-positive connection with the strands 2 and the core strand 1 in accordance with the outer contours of the rope.

The in the A b b. 1 and 2 shown embodiment of a locked wire rope can be used for electrical Cables as well as suspension ropes can be used on suspension bridges or cable cars. in the The first-mentioned application can be some of the strands 2 or the core strand 1 from an electrical There are conductive material, while the filler pieces 3 are made of electrically non-conductive material and in this way also serve as insulators. The wire rope is used as a suspension rope Used in suspension bridges or cable cars, individual wires with a round cross-section can be used instead of strands be used. The filler pieces are expediently made of a wear-resistant material Light metal alloy or a plastic that exhibits favorable wear behavior manufactured.

Other embodiments of locked wire ropes are shown in A b b. 4 to 8. For the designs according to A b b. 4, 5, 7 and 8, the filler pieces 6, 9, 20 and 14 located in the upper part of the rope cross-section are provided with larger outer parts 6 a, 9 a, 20 α and 14 a than the outer parts of the other filler pieces. The wire rope according to A b b. 6 has in the lower part filling pieces 18, which are provided with larger outer parts 18 a than the outer parts of the other filling pieces. In all designs, a number of surrounding wires or strands 2 or 5 or 13 are provided around a core wire or a core strand 1 or 4 or 12, which are combined to form a closed wire rope by means of inserted filler pieces.
