Description
Technical field
The present invention relates to be used for the steel wire rope of the reinforcement usefulness of rubbers such as automobile tyre, conveyer belt, particularly relate to the steel wire rope that has sufficient rubber dipped type and good fatigue durability concurrently.
Background technology
As the steel wire rope of the reinforcement usefulness that is used for rubbers such as automobile tyre, conveyer belt, often adopt for example steel wire rope of the sealing twisting structure (so-called enclosed type) of tight stranded 3～6 wire rods (steel wire) of individual layer in the prior art all the time.Draw neat and coat and be configured as the complex lamellar body (behind the シ-ト) many these steel wire ropes are parallel with elastomeric material, be embedded in the rubber, the steel wire rope of stranded 3 steel wires is called 1 * 3 structure, in addition, according to corresponding 1 * 4,1 * 5,1 * 6 structure that is called of wire rod radical.
But there is longitudinally continuous space in so case type steel wire rope in that rope is inner, and during shaping composite sheet body, the space of this rope inside can not immersed elastomeric material and get off as voids left always utilizing the elastomeric material coated cable.And this space is immersed rope inside and is reduced owing to twist in the rubber on rope surface when the vulcanization of rubber pressurization of tire building operation etc., but can be fully by the rubber landfill, thus the hollow bulb of the suction pipe shape that the rope center is become extend longitudinally and left behind.And, the condensation of gas that generates by elastomeric material and the moisture that produces or be impregnated into this hollow bulb from the moisture of the immersions such as wound of outside etc., consequently, corrosion is from the inner beginning of rope, the intensity decreases of steel wire rope, and the cementability of steel wire rope and elastomeric material descends, and causes the so-called segregation phenomenon that steel wire rope and elastomeric material are peeled off, and this becomes the main cause that product life significantly shortens.
Again, be immersed in the inside of restricting in order to make elastomeric material, also can consider the steel wire rope that (so-called opening) constructed in the gap loose open twisting of twisting of single-layer stranding on one side is set between each wire rod on one side, this steel wire rope uses in the prior art always.But, the steel wire rope of open twisting structure, make elastomeric material fully be immersed in inner then must the making of rope and take bigger gap (at least more than 0.01mm) between each wire rod, the movably free space of each wire rod becomes big when the gap is big, so produce the biasing of wire rod etc., be twisted in and vertically become inhomogeneous, be easy to generate when applying alternating bending stress and buckle, again, because the extension under the utmost point underload is big, so not only operation task is poor, and the complex lamellar body when being shaped under the effect of the tension force that applies the gap reduce, it is inner that elastomeric material often can not fully be immersed in rope.
Therefore, developed following individual layer twisting (Unit Layer Twist
) steel wire rope, this steel wire rope is not by having the wire rod with grazing of other fine wrinkles processing to carry out stranded forming (for example, with reference to special fair 7-68673 communique, No. 3179915 communiques of the special permission mat woven of fine bamboo strips etc.) to wire rod with minor spiral shape except that the spiral fine wrinkle of the twisting that is used to restrict or wavy fine wrinkle with except that the spiral fine wrinkle of the twisting that is used to restrict.
The steel wire rope of individual layer twisting can be considered to a kind of like this steel wire rope, that is: be as mentioned above have the outer minor spiral shape of spiral fine wrinkle of the stranded twisting that is used to restrict or wavy fine wrinkle wire rod and except that the spiral fine wrinkle of the twisting that is used to restrict and do not have other fine wrinkles to process the structure of the wire rod with grazing of (く せ pay け), thereby, even twisting self is tight, also can utilize the minor spiral shape of a part of wire rod or wavy fine wrinkle, under stranded state, between wire rod, form the gap that elastomeric material is immersed, and the tension force that the complex lamellar body of relative and elastomeric material is applied when being shaped, the resistance of the wire rod by having grazing suppresses the extension of steel wire rope, can prevent the disappearance of minor spiral shape or wavy fine wrinkle, thereby between wire rod, keep elastomeric material fully to be immersed in the inner gap of rope as far as possible, again, twisting self closely suppresses the extension under the utmost point underload, improve operation task, and can make the twisting longitudinally of restricting stable, buckle even alternating bending stress also is not easy to produce, fatigue durability is good.
But, the stranded steel wire rope that has the wire rod of minor spiral shape or wavy fine wrinkle and have the individual layer twisting that the wire rod of grazing forms, differing to establish a capital has sufficient rubber impregnability and good fatigue durability concurrently.In order to have sufficient rubber dipped type and good fatigue durability concurrently, whenever the rope the wire rod number or gauge or diameter of wire not simultaneously, all must estimate settings such as fine wrinkle processing number, fine wrinkle processing spacing, fine wrinkle working heights according to rubber impregnability and fatigue durability two sides, with definite best setting, and it be very difficult for this to determine.
Summary of the invention
Therefore, problem of the present invention is, obtains to have the rubber product steel cable for strengthening of the individual layer twisting of sufficient rubber dipped type and good fatigue durability easily and conscientiously.
Rubber product steel cable for strengthening of the present invention, be that stranded n root (n=3～6) wire rod and the individual layer twisting that constitutes and at least 1 wire rod have outer minor spiral shape of the spiral fine wrinkle of the twisting that is used to restrict or wavy fine wrinkle, it is characterized in that: have at least 1 of wire rod of helical form or wavy fine wrinkle, steel wire rope is being removed stranded (Twist
ほ ぐ The) wire horizontal after configuration and when projecting to horizontal plane, the maximum of the tangent line of the track of wire rod and the datum line angulation of the spiral fine wrinkle of the twisting that is used to restrict on the perspective plane is 1.2～2.0 times of rope twist angle.
The fine wrinkle of so-called minor spiral shape is meant the fine wrinkle of three-dimensional spiral shape, and so-called wavy fine wrinkle is meant the fine wrinkle with the bidimensional of the shape after the spiral projection, and they any one all be than the little fine wrinkle of spiral fine wrinkle of the twisting that is used to restrict, and has equal effect.Again, the direction of helical form fine wrinkle can be identical with the rope direction of lay, also can be opposite with the rope direction of lay.
At least 1 wire rod in the n root of this steel wire rope (n=3～6) wire rod, have outer minor spiral shape of the spiral fine wrinkle of the twisting that is used to restrict or wavy fine wrinkle, thereby can be formed on the gap that makes under the stranded state between the elastomeric material immersion wire rod, again, at least 1 of wire rod with minor spiral shape or wavy fine wrinkle, horizontal arrangement is removed this wire rod after stranded and the tangent line of wire rod on the perspective plane when projecting to horizontal plane with steel wire rope, with the maximum of the datum line angulation of the spiral fine wrinkle of the twisting that is used to restrict be 1.2～2.0 times of rope twist angle, thereby for example in the complex lamellar body with elastomeric material is shaped, resistance reduces with respect to the decline of load when being subjected to tension force, suppress the extension of steel wire rope, can prevent the disappearance of minor spiral shape or wavy fine wrinkle, between wire rod, can keep making elastomeric material fully to be immersed in the inner gap of rope as far as possible, and the shape that makes twisting also is not easy to produce the fatigue durability good quality production of buckling at the rope longitudinal stability even can become alternating bending stress.
Wire rod about outer minor spiral shape of the spiral fine wrinkle with the twisting that is used to restrict or wavy fine wrinkle, when horizontal arrangement steel wire rope is removed after stranded wire rod and when projecting to horizontal plane, the maximum of the tangent line of the wire rod on the perspective plane and the datum line angulation of the spiral fine wrinkle of the twisting that is used to restrict can not obtain the gap (at least more than the 0.01mm) that elastomeric material fully is immersed in the middle body of restricting as far as possible during less than 1.2 times of rope twist angle.Again, when horizontal arrangement steel wire rope is removed after stranded wire rod and when projecting to horizontal plane, the maximum of the tangent line of the wire rod on the perspective plane and the datum line angulation of the spiral fine wrinkle of the twisting that is used to restrict is during greater than 2.0 times of rope twist angle, the resistance with respect to load of this wire rod diminishes, it is big that the extension of the rope integral body when tension force acts on the steel wire rope becomes, thereby can not guarantee that elastomeric material fully is immersed in the inner gap of rope as far as possible, and the shape of twisting is inhomogeneous, fatigue durability descends.
As mentioned above, if adopt the present invention, then can be easily and acquisition has the individual layer twisting of sufficient rubber dipped type and good fatigue durability conscientiously rubber product steel cable for strengthening.

The specific embodiment
Followingly embodiments of the present invention are described with reference to accompanying drawing.
The steel wire rope of this embodiment is shown in Fig. 1 (a), it is 1 * 3 steel wire rope 10 of constructing that stranded for example 3 wire rods (steel wire) form, by 1 wire rod 11 being made as the wire rod (taenidium) of the outer minor spiral shape fine wrinkle of spiral fine wrinkle with the twisting that is used to restrict, and other 2 wire rods 12 be made as except that the spiral fine wrinkle of the twisting that is used to restrict and do not have the wire rod with grazing (common silk) of other fine wrinkles processing, and stranded they and form.At this, the fine wrinkle of so-called minor spiral shape is meant the fine wrinkle of three-dimensional spiral shape.The direction of helical form fine wrinkle can be identical with the rope direction of lay, also can be opposite with the rope direction of lay.
This steel wire rope is and for example shown in (b) of Fig. 1, the steel wire rope of 1 * 3 structure that also stranded for example 3 wire rods (sandwich layer silk) constitute, and by 1 wire rod 21 in it being made as the wire rod of the outer less wavy fine wrinkle of spiral fine wrinkle with the twisting that is used to restrict, and other 2 wire rods 22 be made as except that the spiral fine wrinkle of the twisting that is used to restrict and do not have the wire rod with grazing (common silk) of other fine wrinkles processing, and stranded they and form steel wire rope 20.At this, so-called wavy fine wrinkle is meant the fine wrinkle that is shaped as bidimensional after the spiral projection.
Wire rod the 11, the 21st with helical form or wavy fine wrinkle, following this wire rod, promptly other wire rods 12,22 with the tool grazing have same gauge or diameter of wire, and as shown in Figure 2, fine wrinkle spacing P1 is less than lay P, P
1=0.1P～0.7P is when gauge or diameter of wire is made as d, with the overall diameter d of outward appearance
1According to d
1=(d+2/100mm)～(d+2/10mm) fine wrinkle is processed into helical form or wavy like that.At this, so-called fine wrinkle spacing P
1Be meant the spacing of helix pitch of the finished wire rod of fine wrinkle (with reference to Fig. 2) or ripple, the diameter d of so-called outward appearance
1Be meant, be processed into vertical circumcircle A1[that looks of spiral helicine wire rod 11 with reference to Fig. 1 (a) from fine wrinkle] diameter, the wave height { be equivalent to from vertical outer tangent projection of looking oval A2[] long diameter } of perhaps processing rugose wire rod 21 from fine wrinkle with reference to Fig. 1 (b).
And, be that 1 wire rod is when having the steel wire rope 10 of wire rod 11 of the outer minor spiral shape fine wrinkle of the spiral fine wrinkle of the twisting that is used to restrict, the wire rod 12 (common silk) that except that the spiral fine wrinkle of the twisting that is used to restrict, does not have other fine wrinkles processing, remove stranded back horizontal arrangement and project to track on the horizontal plane shown in Fig. 3 (a), the datum line r1 angulation α 1 of the tangent line t1 on the perspective plane and the spiral fine wrinkle of the twisting that is used to restrict, be how many times all with rope twist angle the same angle, or the following angle of rope twist angle, but wire rod 11 (taenidium) about the outer minor spiral shape fine wrinkle of the spiral fine wrinkle with the twisting that is used to restrict, remove stranded back horizontal arrangement and project to track on the horizontal plane shown in Fig. 3 (b), though the datum line r2 angulation α 2 of the tangent line t2 on the perspective plane and the spiral fine wrinkle of the twisting that is used to restrict is local but greater than the rope twist angle, the maximum of this angle [alpha] 2 is processed into 1.2～2.0 times of rope twist angle by fine wrinkle.
Again, be 1 wire rod be when having the steel wire rope 20 of wire rod 21 of the outer less wavy fine wrinkle of the spiral fine wrinkle of the twisting that is used to restrict too, wire rod 21 about the outer less wavy fine wrinkle of the spiral fine wrinkle with the twisting that is used to restrict, remove stranded back horizontal arrangement and project to track on the horizontal plane, though the datum line r2 angulation α 2 of the tangent line t2 on the perspective plane and the spiral fine wrinkle of the twisting that is used to restrict is local but greater than the rope twist angle, the maximum of this angle [alpha] 2 is processed into 1.2～2.0 times of rope twist angle by fine wrinkle.
These steel wire ropes 10,20 for example coat half finished rubber around and are configured as the complex lamellar body compound with elastomeric material, for example imbed in the rubber of tire body when the tire as tyre reinforcement.At this moment, when when coating half finished rubber around the steel wire rope 10,20, half finished rubber is immersed in rope inside from clearance C 1, the C2 of 12,22 in the wire rod 11,21 of fine wrinkle processing and straight wire rod, vulcanizes when tire, and is impregnated into hollow bulb B1, the B2 at rope center.At this moment, steel wire rope 10,20 have be used to the to restrict wire rod 11 of outer minor spiral shape of the spiral fine wrinkle of twisting or wavy fine wrinkle, 21, the maximum that is processed into the tangent line t2 on the perspective plane that removes stranded back horizontal arrangement and project to the track on the horizontal plane and the datum line r2 angulation α 2 of the spiral fine wrinkle of the twisting that is used to restrict by fine wrinkle is 1.2～2.0 times of rope twist angle, thereby in the complex lamellar body with elastomeric material is shaped, resistance reduces with respect to the decline of load when working tension, steel wire rope 10,20 extension is suppressed, can keep elastomeric material fully to immerse the inner gap of rope as far as possible, and make the dimensionally stable of twisting, also be not easy to produce the fatigue durability good quality production of buckling even become alternating bending stress.
When projecting to horizontal plane when the steel wire rope 10,20 of the wire rod 11,21 of minor spiral shape outside the spiral fine wrinkle with the twisting that is used to restrict or wavy fine wrinkle being removed these wire rod 11,21 horizontal arrangement after stranded, the maximum of the tangent line t2 of the wire rod 11,21 on the perspective plane and the datum line r2 angulation α 2 of the spiral fine wrinkle of the twisting that is used to restrict can not obtain to make elastomeric material fully to immerse the gap (at least more than 0.01mm) of rope middle body during less than 1.2 times of rope twist angle as far as possible.Again, when projecting to horizontal plane when steel wire rope 10,20 being removed wire rod 11,21 horizontal arrangement after stranded, the maximum of the tangent line t2 of the wire rod 11,21 on the perspective plane and the datum line r2 angulation α 2 of the spiral fine wrinkle of the twisting that is used to restrict is during greater than 2.0 times of rope twist angle, this wire rod 11,21 reduces with respect to the resistance of load, the extension of the rope integral body on steel wire rope 10,20 during working tension increases, thereby can not guarantee that elastomeric material fully is immersed in the inner gap of rope as far as possible, the shape unshapeliness of twisting, fatigue durability descends.
In addition, in illustrated embodiment, to constitute steel wire rope 10, each 2 wire rod 12 in 3 wire rods of each of 20,22 are designed to have the wire rod of grazing, with each wire rod of 1 11,21 are designed to have the wire rod of minor spiral shape or wavy fine wrinkle, this has each 1 wire rod 11 of minor spiral shape or wavy fine wrinkle, the stranded back of 21 releasing horizontal arrangement and project to the tangent line t2 of track on the perspective plane on the horizontal plane, with the maximum of the datum line r2 angulation α 2 of the spiral fine wrinkle of the twisting that is used to restrict be 1.2～2.0 times of rope twist angle, but wire rod 11 with minor spiral shape or wavy fine wrinkle, the 21st, constitute steel wire rope 10, at least 1 in 20 the wire rod gets final product, also many (also all).Again, wire rod the 11, the 21st with helical form or wavy fine wrinkle is in the time of many, the maximum of removing stranded back horizontal arrangement and projecting to the tangent line t2 of track on the perspective plane and the datum line r2 angulation α 2 of the spiral fine wrinkle of the twisting that is used to restrict on the horizontal plane is 1.2～2.0 times of such wire rods of rope twist angle, can be at least 1, also many (also all).
Again, illustrated embodiment be the situation of 1 * 3 structure, but the present invention is applicable to the steel wire rope of 1 * 4,1 * 5 and 1 * 6 structure too.
The experimental result of the sample of the steel wire rope of the various structures of the brass coating many wire rods in the table 1 stranded surface of demonstration.One of rope of the present invention (embodiment) is a steel wire rope as follows, that is: 1 * 3 structure, gauge or diameter of wire 0.30mm, radical with wire rod of less wavy fine wrinkle be 1, rope apart from (lay) 16mm, strand angle (rope twist angle) 3.875 degree, ripple fine wrinkle processing maximum angle (removes stranded back horizontal arrangement and project to the maximum of the tangent line of track on the perspective plane and the datum line angulation of the spiral fine wrinkle of the twisting that is used to restrict on the horizontal plane) are that 7.1 degree, ripple fine wrinkle processing maximum angle are 1.832 with the ratio that twists the angle; The another rope of rope of the present invention (embodiment) is a steel wire rope as follows, that is: 1 * 4 structure, gauge or diameter of wire 0.30mm, radical with wire rod of less wavy fine wrinkle are that 2, rope are 1.313 apart from 16mm, strand angle 4.761 degree, ripple fine wrinkle processing maximum angle 6.25 degree, ripple fine wrinkle processing maximum angle with the ratio at strand angle.And, one of comparative example is a steel wire rope as follows, that is: 1 * 3 structure, gauge or diameter of wire 0.30mm, radical with wire rod of less wavy fine wrinkle are that 1, rope are 1.161 apart from 16mm, strand angle 3.875 degree, ripple fine wrinkle processing maximum angle 4.5 degree, ripple fine wrinkle processing maximum angle with the ratio at strand angle; The another example of comparative example is a steel wire rope as follows, that is: 1 * 3 structure, gauge or diameter of wire 0.30mm, radical with wire rod of less wavy fine wrinkle are that 1, rope are 2.039 apart from 16mm, strand angle 3.875 degree, ripple fine wrinkle processing maximum angle 7.9 degree, ripple fine wrinkle processing maximum angle with the ratio at strand angle.Again, example was a steel wire rope as follows in the past, that is: the enclosed type of 1 * 3 structure, gauge or diameter of wire 0.30mm, rope are apart from 16mm, strand angle 3.875 degree.
(table 1)
In this experiment, on each steel wire rope, apply and be embedded under the state of tensile load of 49N in the rubber after the sulfuration, wire rod is extracted and stripped to steel wire rope from rubber, observe the wire rod complete cycle, measure the area occupation ratio that contacts with elastomeric material, be expressed as " rubber dipped type (%) ".
Again, the tensile load that applies 49N on each steel wire rope is expressed as " underload ductility " to measure ductility.
Again, the steel wire rope of same specification is embedded in a plurality of rubber lamellar bodies, on this lamellar body, repeats 3 belt wheel flexural fatigues of certain number of times, from the rubber lamellar body, take out rope afterwards and measure fracture strength, compare with the fracture strength before the fatigue test, its result is expressed as " fatigue durability ".The less more fatigue durability of index is low more.
Again, when making steel wire rope, the complexity of the operation when the complex lamellar body is shaped and the operability exponential representation of rope are " operation ".The big more operation of index is high more.
Rope of the present invention (embodiment) is good on rubber dipped type and fatigue durability, and the underload ductility is more less, and the operation difference also is improved.Relative with it, the ratio that the steel wire rope of comparative example has exceeded ripple fine wrinkle processing maximum angle and strand angle is 1.2～2.0 scope, this ratio is the steel wire rope of 1.161 (less than 1.2), the rubber impregnability is poor, and this ratio is the steel wire rope of 2.039 (greater than 2.0), the underload ductility is big, and fatigue durability and operation are poor.
