Definitions
- the invention relates to an elevator rope for use in an elevator for persons, goods, warehousing and any other appliance similar to that. Furthermore a method to produce such elevator ropes is disclosed.
- the inventors therefore sought other ways to solve the friction problem and cracking problem.
- the object of the invention is to provide an elevator rope of which the friction with a sheave can be tuned at will. It is a further object of the invention to provide an elevator rope with a particular coefficient of friction with the sheave of an elevator. Another object of the invention is to provide a reinforced elastomer jacket that reduces cracking of the polymer. Also the method to produce such an elevator rope is the subject of the invention. The invention is set out in the appended set of claims.
- an elevator rope comprising a steel cord and an elastomer jacket surrounding the steel cord.
- the elevator rope further comprises one or more yarns wrapped, braided or knitted around the steel cord. These one or more yarns are integrated into the elastomer jacket.
- the one or more yarns wrapped, braided or knitted around the steel cord form a pattern on said steel cord that comes through, progresses, emerges, imprints or reaches through the polymer jacket to the surface of the elevator rope.
- the load bearing member of the elevator rope is a steel cord i.e. a cord comprising multiple steel filaments.
- a steel rope - generally considered to be of larger size e.g. larger than 8 mm - is also considered to be a steel cord.
- the steel cord may comprise other fibers than steel filaments. In any case the largest part of the load on the steel cord must be carried by the steel filaments. Alternatively the steel cord may consist only out of steel filaments.
- the elevator rope preferably comprises one single steel cord.
- the elevator rope has a substantial circular cross section as opposed to the belt tension members of WO99/43589 that have a thickness that is smaller than the width of the tension member.
- the filaments In order to limit the diameter of the elevator rope, the filaments have a high tensile strength.
- the tensile strength 'Rm' (in N/mm 2 or MPa) of a steel filament is its breaking load (in N) divided by its cross sectional area (in mm 2 ).
- the tensile strength expressed in N/mm 2 is larger than 3000 - 2000 ⁇ wherein ' ⁇ ' is the equivalent diameter of the steel filament in mm, i.e. the diameter of a round filament having the same cross sectional area as the filament.
- ' ⁇ ' is the equivalent diameter of the steel filament in mm, i.e. the diameter of a round filament having the same cross sectional area as the filament.
- Currently, even higher tensile strengths such as higher than 3500 - 2000 ⁇ are considered.
- the diameters of the filaments envisaged for the steel cord are between 0.15 mm and 0.50 mm, or more preferably between 0.20 to 0.40 mm. Hence, tensile strengths of the filaments are above 2000 N/mm 2 . Generally within the steel cord of the invention different filament diameters are used in order to geometrically fit together the filaments and strands in the steel cord.
- plain carbon steel In order to reach these high tensile levels plain carbon steel is used that is sufficiently far cold deformed by means of wire drawing.
- a typical steel composition has a minimum carbon content of 0.65%, a manganese content ranging from 0.40% to 0.70%, a silicon content ranging from 0.15% to 0.30%, a maximum sulphur content of 0.03%, a maximum phosphorus content of 0.30%, all percentages being percentages by weight.
- copper, nickel and/or chromium There are only traces of copper, nickel and/or chromium.
- the outer surface of the filaments are coated with a functional coating to promote adhesion and/or to retard corrosion and/or to improve fatigue wear.
- An adhesive coating is e.g. brass plated steel filaments that can adhere well to rubber in case a rubber elastomer jacket is envisaged.
- organo functional silanes, titanates or zirconates can be used to improve adhesion with polyurethanes. The latter can be conveniently combined with a zinc coating that brings and improved corrosion resistance as well.
- mineral or synthetic oils - preferably compatible with the elastomer of the jacket - can be used that reduce fretting between filaments and at the same time inhibit corrosion.
- the steel cord is a multi-strand steel cord that is built up of strands of steel filaments.
- a preferred embodiment has a core strand made of two, three or more strands.
- Another preferred embodiment is one wherein the cord comprises a central steel core strand surrounded by a layer of inner layer steel strands forming an inner strand.
- On this inner strand layer an outer layer of outer layer steel strands is cabled.
- the lay length and direction of inner layer steel strands and outer layer steel strands are preferably differing from one another and/or opposite to one another.
- the lay length of inner layer of strands is chosen between 5 to 12 times the diameter of the inner strand and the lay length of the outer layer strands between 5 to 15 times the diameter of the steel cord.
- the lay length of the outer layer strands is the cord lay length.
- the number of inner layer strands is from 5 to 8, while the number of outer layer strands is from 6 to 12. In a preferred embodiment there is no common divisor between the number of inner layer strands and the number of outer layer strands. This results in less interlayer pressure between strands.
- Strands are steel filaments that are twisted together.
- the twisting can be done in a single step wherein all steel filaments of the strand obtain the same lay length and direction.
- Simple constructions with equal diameters such as three filaments twisted together (3 ⁇ 1) or six filaments around a single core wire (1+6) are preferred for the core and inner strands.
- the lay length of the filaments in the strands is from 10 to 20 times the diameter of the strand.
- Strands with a high metallic fill factor are more preferred for the outer strands, as they are highest in number and must take most of the load.
- filament diameters are chosen according a Warrington, Seale, filler, or Warrington-Seale configuration. Exemplary configurations are 1+6-6-6 Warrington, 1+6+6F+12 filler, 1+9-9 Seale. These configuration have metallic fill factors of 75 % and higher.
- strands can be of the multilayer type.
- a core strand or filament is covered with a layer of filaments having a different lay length and/or direction compared to the underlaying layer.
- Multilayer strands are somewhat less preferred due to their point contacts between filaments and lower metallic fill factor.
- the diameter of the steel cord 'd' is in principle not limiting the invention.
- the invention can be used with steel cords with diameter from 1 to 20 mm or even larger.
- the diameter of the steel cord 'd' is less than 8 mm, even more preferably lower than 7 mm as for example 4.5, 5, 5.5 or 6 mm.
- the invention can be advantageously used from diameters 2 mm and higher thereby not excluding its use below that limit.
- the elevator rope In order to spread and reduce the pressure on the high tensile steel filaments, the elevator rope is provided with an elastomer jacket that completely surrounds and encases the steel cord.
- the elastomer can e.g. be a thermohardening elastomer like rubber. Rubber has some particular advantages in that it is wear resistant and enables very good adhesion with brass coated filaments. However, it generates a lot of friction with other objects making it less preferred for the coating of an elevator rope. Also the vulcanisation requires a lot of energy and is an additional step to extrusion.
- thermoplastic elastomers that can readily be extruded around the steel cord and do not need an additional vulcanisation step. Moreover, the friction coefficient with a steel sheave is lower than that of rubber.
- thermoplastic elastomer can be selected from the group consisting of styrenic block copolymers, polyether-ester block copolymers, thermoplastic polyolefin elastomers, thermoplastic polyurethanes and polyether polyamide block copolymers.
- thermoplastic polyurethanes comprise ether-based polyurethanes, ester-based polyurethanes, ester-ether based polyurethanes, carbonate-based polyurethane or any combination thereof.
- Preferred polyurethanes are polyurethanes having a good hydrolysis resistance and low temperature flexibility such as ether-based polyurethanes.
- the friction coefficient (static or dynamic) of the elastomer jacket can also be altered by adding fillers to the elastomer compound.
- Particular noteworthy fillers are high molecular weight polymer particles of spherical or non-spherical shape with a size between 5 to 500 ⁇ m, or 20 to 250 ⁇ m or most preferred between 50 to 100 ⁇ m.
- High molecular weight polymers are - for the sake of this application - polymers with a molecular weight higher than 0.5•10 6 g/mol, for example between 1•10 6 and 15•10 6 g/mol, or more preferred between 2•10 6 and 9•10 6 g/mol.
- Particularly preferred particles are ultra-high molecular weight polyethylene (UHMW-PE) particles or ultra-high molecular weight poly dimethyl siloxane particles.
- UHMW-PE ultra-high molecular weight polyethylene
- the elevator rope comprises yarns that are wrapped, braided or knitted around the steel cord.
- 'yarn' any type or kind of non-metal wire i.e. a slender, strong monofilament, strand or cord purposively designed to be used in weaving, sewing or other textile work. They can be made of a single filament or of multiple filaments or fibres that are spun together (spun yarn) or laid together without intended twist (zero-twist yarn). Yarns can also be in the form of a narrow strip or tape of material.
- Yarns are made of synthetic material selected from the group consisting of glass fibres, poly-aramide fibres, poly(p-phenylene-2,6-benzobisoxazole) fibres, polyurethane fibres, carbon fibres, polyolefin fibres, polyamide fibres, polyester fibres, poly ethylene terephthalate fibres, polycarbonate fibres, polyacetal fibres, polysulfone fibres, poly phenylene sulphide fibre, polyether ketone fibres , polyimide fibres, polyether imide fibres or mixtures thereof.
- synthetic material selected from the group consisting of glass fibres, poly-aramide fibres, poly(p-phenylene-2,6-benzobisoxazole) fibres, polyurethane fibres, carbon fibres, polyolefin fibres, polyamide fibres, polyester fibres, poly ethylene terephthalate fibres, polycarbonate fibres, polyacetal fibres, polysulfone fibres, poly phenylene
- the yarns are natural or semi-synthetic fibres selected from the group consisting of sisal, flax, cotton, hemp, silk, basalt, cellulose based fibres or mixtures thereof. Rayon is a specific example of semi-synthetic regenerated cellulose fibre.
- the yarns are provided with an adhesive size, a coating that improves adhesion with the elastomer of the jacket.
- an RFL (resorcinol formaldehyde latex) dip is suggested.
- thermoplastic elastomers aqueous size solutions based on starch, acrylic polymer, polyvinyl alcohol or others, dissolved in hot water together with a wax, such as polyolefin wax are recommended. After dipping and drying a layer forms on the yarn.
- Non-aqueous sizes comprising a heat meltable polymer and a wax such as a polyolefin wax can also be considered.
- heat meltable polymer sizings are acrylate ester or methacrylate esters. Best is if the yarn material adheres to the polyurethane without a need for a size for example when the yarn as well as the jacket elastomer is polyurethane based.
- Yarns are wrapped around the steel cord by encircling, by winding, by spiralling the yarns around the steel cord.
- the wrapping can be done in the direction of the cord lay or opposite to the direction of the cord lay. Possibly more than one yarn can be wound around at the same yarn lay length, or the yarns may have a different yarn lay lengths and/or may be wound in opposite direction. Wrapped yarns can be easily unwound from the steel cord by unwinding them in reverse order and in opposite direction: they will not entangle.
- the yarns can be braided around the steel cord.
- two or more yarns are wound around the steel cord of which at least one yarn winds opposite to the others.
- the yarns have a yarn lay length that is equal to the axial distance needed by the yarn to make one turn around the steel cord.
- the at least one yarn alternatingly crosses under and over one or more of the remaining yarns. This results in a weaving pattern on the surface of the steel cord.
- the number of yarns evolving in the one winding direction is equal to the number of yarns running in the opposite direction. All kinds of weaves like plain weave, twill weave or satin weave are possible. Single yarns will not easily disentangle from the resulting braid.
- the yarns are knitted or stitched around the steel cord. Preferably this is done in a warp knit or stitch process.
- Single knitted or stitched yarns do not completely circumscribe the steel cord.
- a yarn lay length can still be defined as being the distance between two contacts of the same pair of yarns.
- One, two or more yarns can be knitted or stitched around the steel cord. Removal of a single yarn results in the other yarns coming loose.
- each lay length of the one or more yarns is shorter than the cord lay of the steel cord. This ensures that the yarns cross the outer strands of the steel cord under an angle and that the yarns are not oriented parallel to the steel strands.
- At least two yarns are wrapped around the steel cord in opposite directions.
- crossings will always occur diametrically opposite and at the same circumferential position. This results in a repeated pattern of protrusions at the surface of the elastomer.
- the wrappings are with lay lengths that are co-prime to one another (for example 15 and 14 mm, or 5 and 9 mm,...) crossings will not occur diametrically to one another and are evenly spread around the circumference of the steel cord. It is also possible that the lay length is varied along the length of the steel cord. Wrapping is a preferred method to apply the yarns as it operates at the highest linear speeds.
- the wrapping, braiding or knitted yarns should not cover the steel cord completely. On the contrary: it is the intention that sufficient parts of the steel cord remain open for the ingress of the elastomer jacket in order to consolidate, to unite the elevator rope.
- the yarns are therefore embedded in the elastomer jacket and are an integral part of the elastomer jacket. As such the yarns reinforce the elastomer jacket and prevent it from cracking during extended use.
- a further purpose of the yarn is to introduce a controlled unevenness to the outer surface of the elastomer jacket.
- This controlled unevenness influences the friction coefficient of the elevator rope.
- a small bulging at the surface of the elastomer jacket appears.
- the number of bulges at the surface of the elastomer jacket can also be controlled.
- An open yarn layer further improves the mechanical anchorage of the jacket to the steel cord.
- less than 60% of the outer surface of the steel cord is covered with the one or more yarns. If the coverage degree is too high the yarn will isolate the polymer jacket from the steel cord thereby jeopardising the integrity of the elevator rope. A too high coverage degree will also lead to a too smooth surface of the elastomer jacket. At least 5% of the surface must be covered with yarn in order to at least have a beneficial effect. If there is not enough yarn present the jacket surface will remain unaffected and the reinforcement of the jacket will be insufficient. Other possible coverage degrees are between 5 and 50% or between 10 and 50%, or between 15 and 45 %.
- the width of the yarn should be less than 30% of the diameter of the steel cord, or even less than 20%.
- the width of the yarn is the dimension in a direction perpendicular to the yarn as it is in position on the steel cord as during wrapping, braiding or knitting the yarn can be flattened.
- the thickness of the yarn is preferably more than 1%, or even more than 5% of the diameter of the steel cord in order to leave a sufficient imprint at the outer surface of the polymer jacket.
- the thickness of the wrapped, braided or knitted yarns should neither be too large nor too small compared to the thickness of the elastomer jacket.
- the thickness of the elastomer jacket is equal to half the difference between the diameter of the elevator rope measured with elastomer jacket and the steel cord diameter. These diameters are to be measured with a micrometer with large anvils. With 'large anvils' is meant circular anvils with a diameter that is larger than at least the cord lay length of the steel cord. As a 'diameter' the average of the minimum and maximum measured value over the circumference of the elevator rope or steel cord is used. Hence the jacket thickness also includes the thickness of the yarn.
- the thickness of the elastomer jacket is between 5 to 50% of the diameter of the steel cord with more preferred thicknesses between 5 to 30%, or 5 to 25%.
- the thickness of the yarn is meant the radial size of a single yarn when in position around the steel cord.
- This thickness of the yarn is less than the thickness of the elastomer jacket.
- the yarn must be covered by the polymer at least when the elevator rope is in its fresh state. During use, some of the yarns may surface at the elastomer jacket. Preferably the thickness of the yarn is less than 75% of the thickness of the elastomer jacket.
- the yarns should also have a minimum amount of thickness e.g. 5% of the elastomer jacket. This in order that the imprint of the yarn continues to the surface of the elastomer jacket. Other favourable ranges are: between 10% and 60% between 10% and 50%.
- the contact surface of the elastomer jacket to the flat surface can be determined (for example by inking the elastomer surface or by using pressure sensitive paper).
- a swing between 10% to 90% of the elastomer jacket contact surface can be obtained.
- An advantageous range is that between 10% and 60% of the elastomer jacket contacts the flat surface when rolled out. Alternative ranges are between 10% to 50%, 15% to 40% and 20% to 40%.
- the elevator rope is intended for use in an elevator of goods and/or persons. Its size and strength as described above are such that it can be used with small drive sheaves enabling the use of direct drive motors without gearbox.
- the elevator rope can be used with sheaves of diameter 'D' that are equal to or smaller than 40 ⁇ d, 'd' being the diameter of the steel cord.
- the yarn mantle improves the drag of the polymer during extrusion.
- the surface of the elevator cord thereby gets a substantially round cross section.
- the centricity of the steel cord in the elevator rope is also improved.
- the yarn mantle prevents sleeving of the steel cord strands during extrusion.
- a large pressure is exerted on the steel cord, the outer strands tend to be pushed back at the entrance of the extrusion head. This pushing back results in an accumulation of extra length of the outer strands thereby opening the steel cord. This may even lead to steel cord fracture if two outer strands exchange position.
- the presence of the yarn mantle prevents the outer strands to accumulate the extra length and therefore the occurrence of sleeving.
- Filaments are made of far drawn plain carbon steel with carbon content in excess of 0.70 wt%C.
- the tensile strength of the filaments is between 2200 to 2900 N/mm 2 depending on the size of the filament.
- the filaments are hot dip galvanised.
- the cross section of the steel cord is indicated with 110 in Figure 1b .
- the steel cord has a diameter of 5.1 mm.
- the intermediate product was led through a dipping tank containing a solution of 1.5 vol. % of N-(2-amino ethyl)-3-amino propyl tri methoxy silane (a functionalized organo silane) dissolved in a mixture of isopropanol and water. Air-drying followed the dipping.
- the intermediate product was further processed in an extrusion line and coated with clear polyurethane (Desmopan ® of Bayer).
- An elastomer jacket 140 is thus formed that follows the underlying texture of the yarn and shows an uneven surface that reflects the underlying yarn mantle.
- the final outer diameter of the cord was 5.65 mm making the thickness of the elastomer jacket 0.275 mm or 5.4 % of the steel cord diameter.
- a ⁇ surface print' was made of the outer surface of the elastomer jacket by taking a test piece of 10 cm long from the elevator cord, inking the outer surface and rolling it out over a sheet of paper while exerting a diametrical force of 10 N on the test piece.
- This surface print is represented in Figure 4b . From the surface print a 1200 dpi digitized image is made and the number of non-white pixels to the total of pixels is counted. In this case 17% of all pictures showed colour i.e. the 17% of the surface of the elastomer jacket contacted the flat surface. Furthermore, the figure 4b shows a distinct; semi-regular pattern that reflects the yarn distribution embedded in the elastomer jacket.
- a steel cord comprises a core strand of type 1+6 surrounded by 5 inner layer strands also of type 1+6.
- the outer layer comprises 7 strands of 19 filaments in Warrington configuration. Again the cord has a diameter of 5.1 mm.
- yarns 220, 220', 222, 222' are braided around the steel cord.
- Yarns 220, 220' are twisted in the Z direction, while yarns 222, 222' are twisted in the S direction.
- the yarns cross each other in a plain weave (one under, one over).
- Each yarn has a lay length of 10.2 mm but as there are four yarns, the axial distance between two consecutive yarns is only 2.55 mm.
- the yarns are poly phenylene sulphide (PPS) monofilament yarns of diameter 0.20 mm.
- the coverage ratio of the steel cord surface is 9.3%.
- This intermediate product was again treated with the same adhesive and coated with Desmopan ® .
- the resulting elevator rope had a diameter of 5.65 mm resulting in an elastomer jacket thickness of 0.275 mm or 5.4% of the steel cord diameter.
- the ratio of yarn thickness to elastomer jacket thickness is thus 73%.
- the resulting fingerprint of the surface of the elastomer jacket is shown in Figure 4a .
- the ratio of contact surface to circumferential surface of the elastomer jacket is 24%.
- the steel cord 310 of the third embodiment 300 as represented in Figure 3a and 3b is made according: 0.44 + 6 ⁇ 0.37 7 z + 12 ⁇ 0.34 14 z + 6 ⁇ 0.34 + 6 ⁇ 0.31 10 s + 12 ⁇ 0.29 20 s 50 Z
- the core strands and the outer strands are multilayer strands wherein a core wire is surrounded by six outer wires with a first lay length that are on their turn surrounded by twelve outer wires wound with a second lay length.
- the filaments have tensile strengths between 2300 N/mm 2 and 2700 N/mm 2 .
- the steel cord 310 is surrounded by a cellulose based rayon fibre, twisted to a single yarn with a linear density of 248 tex.
- Three yarns 320, 322 and 324 are knitted around the steel cord 310, each of the yarn covering radial segments of about 120° each.
- the yarns show a lay-length 'L' that is equal to the axial contact distance between pairwise contacts of the yarns.
