The specific embodiment
Cable of the present invention or band use being used for that people and weight etc. is moved the lowering or hoisting gears such as elevator that thing moves to the position with difference of height; for supporting is moved the weight of thing, it comprises the not resin-coating body of frayed damage of the tension element that formed by wirerope etc. and this tension element of protection.
Even adhere to lubricating oil, coefficient of friction can not decline to a great extent yet, and cable that the wearing and tearing of the resin that slip causes are few or band obtain with following method.
The first, the reduction of coefficient of friction when preventing attaching oil is discharged oil from the minim gap (rubbing surface) of the contact site of the outermost resin of cable or band and sheave groove face.Originally, in the contacting of the outermost resin of cable or band and sheave groove face,, therefore,, approached to clean conditions, and then also can guarantee to draw the frictional force that needs if discharge oil from rubbing surface even adhere to lubricating oil owing to become big because of both adhesions make coefficient of friction.In order to discharge oil from rubbing surface, it is effective improving the hardness of resin and improving the face pressure that takes place on both small contact-making surfaces.Improve under the situation of hardness, be out of shape little and resin does not cave in, so contact area diminishes.Consequently face is pressed and is improved.
The second, the friction of the resin that slip causes produces by the distortion of rubbing surface, therefore, at first by improving the tensile strength of resin, in addition, by doing one's utmost to avoid the resin mother metal to contact with the direct of sheave groove face, suppresses the distortion of resin.Thus, can reduce wear extent.Contact with the direct of sheave groove face for fear of the resin mother metal, can form composite by the solid material of its hard other of mixing ratio in the resin mother metal and realize.
In said method, improve resin hardness, improve resin tensile strength, and in this resin the hybrid solid material be not mutually opposite relation, therefore, can implement these methods simultaneously.Therefore, if implement said method simultaneously, even adhere to lubricating oil, coefficient of friction can significantly not reduce yet, and can obtain the high resin of mar proof.
Below, use description of drawings embodiment.
Embodiment
Fig. 1 is the outer resin-coated pie graph of the cable of expression embodiments of the invention.The outermost resin 1 of resin-coating cable or band contains resin mother metal 1a and insoluble solids additive 1b.In the present embodiment, resin mother metal 1a has adopted thermoplastic polyurethane, and insoluble solids additive 1b has adopted alumina filled thing.The sheave 2 that joins with outermost resin 1 is provided with sheave plating layer 2b on the surface of sheave mother metal 2a.The shape of insoluble solids additive 1b it is desirable to sphere or suitable therewith shape, so that can not make the sheave plating layer 2b on sheave surface that unnecessary damage is arranged when outermost resin 1 and sheave 2 slips, is difficult in addition come off from resin mother metal 1a.
At this, outermost resin 1 also can be called the resin-coating body.
But, only constitute under the situation of outermost resin 1 with resin mother metal 1a, along with slip is carried out, coefficient of friction between the two sharply rises, and thereupon, the wear extent of resin also sharply increases.Coefficient of friction when Fig. 2 represents to use existing general resin and the variation of wear extent.Under the situation of this figure, sliding distance reach 60 meters during coefficient of friction sharply increase, wearing and tearing are carried out.
Fig. 3 represents the skeleton diagram of rotary abrasion tester.In this figure, the wearing character of outermost resin 1 applies tension force by the end at resin-coating cable 3, makes 2 rotations of the sheave that is arranged on the pallet 6 and the sliding test carried out is measured.Coefficient of friction is calculated with the load value of the load cell 5 of the other end that is arranged at resin-coating cable 3 by the weight of counterweight 4.
Fig. 4 is the result of elementary analysis has been carried out in expression to the sheave plating layer surface after sliding by the auger electrons optical splitter figure.Transverse axis is represented the degree of depth of sheave plating layer according to sputtering time, and the longitudinal axis is represented the concentration of element of carbon (C), oxygen (O), phosphorus (P), nickel (Ni) and fluorine (F).Learn that by this figure the carbon of sheave plating layer near surface and the concentration of oxygen uprise.This expression resin is transferred to the sliding surface of plating layer 2b from cable 3.
That is, along with the coefficient of friction that carries out that slides rises and is that the effect of fluorine compounds causes because the transfer printing by resin reduces.In addition, to observe the vestige that resin is out of shape at the sliding surface of outermost resin 1 with the corresponding mode of the transfer printing of resin.
Therefore, the phase I is a purpose with the tendency that inhibition resin wearing amount sharply increases, even also be difficult to produce the mode of resin distortion to slide, at first uses tensile strength sigma r to make resin-coating cable 3 than existing high resin mother metal 1a.And, by sliding test with existingly compare research.
Fig. 5 is the schematic diagram of the resin distortion that produces because of slip of expression.Among this figure, resin mother metal 1a and sheave plating layer 2b (a) partly directly contact when also (b) slides (c) the resin mother metal 1a (d) of adhesion distortion and disrumpent feelings.
Usually, in order to make resin deform portion 7 disrumpent feelings by slip, must surpass the destruction opposing value that resin mother metal 1a is had.Therefore, think that destroying the opposing value is the big resin of failure energy (equaling the long-pending of tensile strength and breaking elongation), sliding causes that wear extent is few.
Usually,,, then can not find big difference, therefore, think to increase failure energy by improving tensile strength sigma r if the material of resin is identical for breaking elongation.
In the present embodiment, consider that be provided with sheave plating layer 2b as the surface elements of sheave 2, still, sheave plating layer 2b may not need to be provided with, and sheave mother metal 2a is exposed as the surface elements of sheave 2 from viewpoints such as antirust, mar proofs.That is, the surface elements of sheave 2 is the metal that constitutes sheave mother metal 2a, resin, pottery etc. under the situation that does not have sheave plating layer 2b, under the situation that sheave plating layer 2b is arranged, is plating materials such as the metal that constitutes sheave plating layer 2b, resin, pottery.
Fig. 6 represents the relation of the tensile strength sigma r of the wear extent of the outermost resin 1 that obtains by sliding test and resin mother metal 1a.Among this figure, the material of resin mother metal 1a is a thermoplastic polyurethane.Show that as this figure the wear extent of outermost resin 1 diminishes greatly with the tensile strength change of resin mother metal 1a.And its tendency is that tensile strength sigma r is that the boundary changes significantly with 25MPa.That is, when the tensile strength sigma r of resin mother metal 1a was lower than 25MPa, the wear extent of outermost resin 1 sharply increased, and therefore, was more than the 25MPa at the required tensile strength sigma r of resin mother metal 1a aspect the inhibition wearing and tearing.
At this, tensile strength sigma r is that benchmark is measured with JIS K7311 (test method of polyurethanes thermoplastic elastomer (TPE)).
In addition, as second stage, attempted doing one's utmost to reduce direct contact of outermost resin 1 and sheave plating layer 2b by in resin mother metal 1a, sneaking into insoluble solids additive 1b.That is, use filler to add resin material, seek the realization of low wearing character by two effects shown in following by outermost resin 1.
(1) makes between resin mother metal 1a and sheave plating layer 2b and have the gap, do one's utmost to reduce direct contact of outermost resin 1 and sheave plating layer 2b.
(2), the fluorine compounds that contain among the sheave plating layer 2b are needed on the outermost resin 1, by the fluorine compounds inhibition friction and the wearing and tearing of transfer printing by scratching brokenly sheave plating layer 2b.
In order to realize the reduction of wear extent by effect (1), importantly sneak into insoluble solids additive 1b at least, and particle diameter and the containing ratio of increase insoluble solids additive 1b are protected resin mother metal 1a than resin mother metal 1a hard.In addition, for shape, be difficult to damage sheave plating layer 2b, and to be difficult to come off from resin mother metal 1a be important.
On the other hand, in order to realize the reduction of wear extent by effect (2), the insoluble solids additive 1b than sheave plating layer 2b hard is necessary at least, but, because damage sheave plating layer 2b is so it is important that the transfer printing amount of fluorine compounds rests on necessary irreducible minimum.
And, insufficient at the start of run fluorine compounds to the transfer printing of outermost resin 1, therefore, can realize low wearing character steady in a long-term by effect (1) in the slip initial stage, after stage can realize the low wearing character of long-term stability by acting on (2).
Therefore, insoluble solids additive 1b needs the suitable material of selection effect (1), (2) establishment for each parameter of (a) material, (b) size, (c) shape, (d) containing ratio.
Fig. 7 is the figure of the coefficient of friction wearing character of the outermost resin when having represented to have used filler to add resin material.In addition, Fig. 8 is the figure of relation of the hardness of expression wear extent of outermost resin and insoluble solids additive.They are for about one of the result of study of the various influence degrees of material, size and the shape of insoluble solids additive 1b example.Sliding test uses the outermost resin 1 that has mixed talcum powder, magnesium hydroxide, calcium carbonate and alumina filled thing respectively to carry out, and has investigated the wearing character of the coefficient of friction and the outermost resin 1 of 2 of various resin-coating cables 3 and sheaves.
Consequently, shown in Fig. 7 (a), in the scope of illustrated insoluble solids additive 1b, the order that coefficient of friction is high is calcium carbonate, secondly is that talcum and magnesium hydroxide are equal, is aluminium oxide afterwards.For the variation of the coefficient of friction of following slip tendency, although can find the effect of mixed packing,, the tendency of rising is still arranged in calcium carbonate, talcum and magnesium hydroxide.On the other hand, can see that the variation tendency of aluminium oxide is different with these, reduce, roughly keep certain value afterwards at the beginning back coefficient of friction that slides.
For wearing character, shown in Fig. 7 (b), in the mode corresponding with the variation of coefficient of friction, the aspect big from wear extent is in order: calcium carbonate, secondly being that talcum and magnesium hydroxide are equal, is aluminium oxide afterwards.For the aluminium oxide of having represented low-friction coefficient, can see the tendency that the increase of amount of friction stops.
So, considered the influence that these insoluble solids additives 1b brings, in material behavior, be conceived to hardness especially, adjust the relation of wear extent with the hardness of insoluble solids additive 1b.This chart is Fig. 8.Transverse axis is a Mohs' hardness, and the longitudinal axis is the wear extent of outermost resin.
Learn according to this figure, lower than the hardness of sheave plating layer 2b and with the situation of the approaching calcium carbonate of its hardness under, the wear extent that causes of sliding is big.This is considered to, a low side hardness near the time, sheave plating layer 2b and insoluble solids additive 1b adhere easily on sliding surface, therefore, insoluble solids additive 1b comes off from resin mother metal 1a, by after slip wear extent is increased.On the other hand, for size and shape, result as shown in Figures 7 and 8 learns, we can say that these influences that are related to wear extent do not exceed the influence that material is a hardness.
Therefore, consider that under the situation of the wearing character of the coefficient of friction of 2 of control resin-coating cable 3 and sheaves and outermost resin 1, the material of insoluble solids additive 1b becomes the significant effects factor from these factors.Think for the size of insoluble solids additive 1b,,, need only in being difficult to the scope that comes off from resin mother metal 1a and consider for the shape of insoluble solids additive 1b as long as in the scope of the strength of materials that does not reduce resin mother metal 1a, consider.
Fig. 9 represents the results of elemental analyses of outermost resin 1 surface of cable being carried out by the auger electrons optical splitter.Be that insoluble solids additive 1b is the situation of aluminium oxide.Be the result who carbon, oxygen, nickel and fluorine is carried out elementary analysis.
When insoluble solids additive 1b is the harder material of the such ratio sheave plating layer 2b of aluminium oxide, show the fluorine compounds that contain are arranged in sheave plating layer 2b in the surface transfer of the outermost resin after the slip 1 from the analysis result shown in this figure.Think that this transfer printing produces low-friction coefficient shown in Figure 7 and low wearing character.
In the scope of insoluble solids additive 1b shown in Figure 7, under the situation of insoluble solids additive 1b beyond aluminium oxide, can not see such transfer printing, therefore, we can say when making the fluorine compounds of sheave plating layer 2b be needed on the outermost resin 1 existence of the insoluble solids additive 1b of material that need be harder than sheave plating layer 2b by slip.
Then, influence degree about the containing ratio of insoluble solids additive 1b has been discussed.Figure 10 represents that insoluble solids additive 1b uses result under the situation of alumina filled thing, that study about the influence of the containing ratio of the wearing character that relates to coefficient of friction between resin-coating cable 3 and the sheave 2 and outermost resin 1.The containing ratio of expression insoluble solids additive 1b be 0.03,0.09 and the situation of 0.21vol% and the situation of 0vol% compare.Show by this figure, manifest significant effect from 0.03vol% (percentage by volume).When 0.03vol% was above, no matter how many containing ratios was, though as seen more or less different low period at slip initial stage coefficient of friction,, coefficient of friction is roughly in co-extensive.In addition, for the wear extent of outermost resin 1, reflection coefficient of friction, any containing ratio are all in same scope.
On the other hand, for the containing ratio of the insoluble solids additive 1b of this trial stretch, the plating layer 2b on sheave surface is born the how damage of degree also study.The damage evaluation of sheave plating layer 2b is after making resin-coating cable 3 and sheave 2 slip 300m, the mensuration of the surface roughness by sheave plating layer 2b and scanning electron microscope carry out surface observation and slide before state compare research.Be meant the state that has been equivalent to use after 20 years behind the so-called slip 300m.
Figure 11 is the slide figure of variation of surface roughness of the sheave plating layer cause of expression.Transverse axis is the aluminium oxide containing ratio, and the longitudinal axis is the cable surface roughness Ra.As shown in this figure, learn when containing ratio is 0.03vol%, damage sheave plating layer 2b hardly, fluorine compounds can be needed on the outermost resin 1.In addition, when containing ratio was 0.21vol%, the reduction of the surface roughness of sheave plating layer 2b was stabilized in 0.5 mu m range.
Think from above result of study, be needed on outermost resin 1 by the plain compound of slip fluorine, and when being condition, be suitable amount below the above 0.21vol% of containing ratio 0.03vol% of insoluble solids additive 1b with the surface roughness that does not change sheave plating layer 2b.Alumina content is under the situation of 0.21vol%, and the sheave surface roughness Ra can be suppressed is 8.3 μ m, and therefore, the coefficient of friction when adhering to for oil is no problem.In addition, from the viewpoint of the reliability of sheave, the wear rate behind 20 years of concave-convex surface is suppressed to be-5% with the surface roughness Ra benchmark.That is, have the sheave surface roughness Ra is remained requirement more than the 8.3 μ m.In addition, the better scope of containing ratio is below the above 0.09vol% of 0.03vol%.
In addition, the containing ratio that uses alumina filled thing is the different outermost resin 1 of tensile strength sigma r of 0.03vol% and resin mother metal 1a equally, has investigated the coefficient of friction between resin-coating cable 3 and the sheave 2 and the frictional behavior of outermost resin 1.Figure 12 coefficient of friction that to be comparison caused by the tensile strength of resin mother metal 1a and the chart of wearing character.Among this figure, relatively the tensile strength sigma r of resin mother metal 1a is the situation of 19MPa and the situation of 34MPa.
Learning thus, even contain alumina filled thing 0.03vol%, is under the situation of 19MPa at the tensile strength sigma r of resin mother metal 1a, and the wear extent of outermost resin 1 increases in early days.Under this situation, coefficient of friction shows the tendency that descends in the initial stage of sliding, and, also cause the distortion of the resin mother metal 1a that keeps alumina filled thing, therefore, think and compare to the transfer printing of outermost resin 1 with the plain compound of fluorine, be alumina filled thing come off and the resin distortion causes.
Therefore, in order to reduce the wearing and tearing of outermost resin 1, need to use and mix insoluble solids additive 1b, and tensile strength sigma r is high and be difficult to produce coming off and the resin mother metal 1a of the distortion of resin mother metal 1a of insoluble solids additive 1b.
As mentioned above, by with tensile strength be resin more than the 25MPa as resin mother metal 1a, and add the insoluble solids additive 1b (filler) harder than sheave plating layer 2b, can realize the low wearing character of outermost resin 1.
The mechanism of the reduction of the coefficient of friction when on the other hand, needing this method of checking whether the hardness that improves resin mother metal 1a to be suppressed attaching oil has a negative impact.
Figure 13 represents result that the outermost resin 1 about using tensile strength sigma r as 20MPa among the described sliding test result of Fig. 6 is obtained coefficient of friction and the chart put in order of the relation of the hardness Hr of resin mother metal 1a when paying oil.Learn that from this figure the required coefficient of friction of the traction of elevator can be realized by using the above resin mother metal 1a of resin hardness 94 (JIS-A standards).
At this, resin hardness is that benchmark is measured with JIS K7311 (test method of polyurethane series thermoplastic elastomer (TPE)).
So with respect to the resin mother metal 1a with the above hardness of this value, affirmation does not change hardness Hr and tensile strength sigma r is brought up to more than the 25MPa, and has added under the situation of alumina filled thing, what kind of influence the coefficient of friction during to attaching oil produces.Sliding test is following to be carried out: be that the containing ratio of having made alumina filled thing on the resin mother metal 1a of 34MPa, hardness Hr97 (JIS-A standard) is respectively 0.03,0.09 and the outermost resin 1 of 0.21vol% at tensile strength sigma r, various resin-coating cables 3 are carried out.
Figure 14 represents its result of the test.Demonstration is with respect to various alumina filled thing containing ratios, the coefficient of friction when the cleaning of attaching oil not under 28 ℃ the situation, and temperature is a coefficient of friction under the situation of 28 ℃ and 50 ℃ during attaching oil.Learn that from this figure the coefficient of friction during cleaning shows the tendency of some risings for a long time at the content of alumina filled thing.But, coefficient of friction during for attaching oil is not seen big difference, in addition, the value of the resin hardness 97 (JIS-A standard) of this value and Figure 13 about equally, therefore, the mechanical device of the reduction of the coefficient of friction of raising that we can say the interpolation of alumina filled thing and tensile strength sigma r when suppressing attaching oil does not cause negative effect.
Therefore, by being more than the 25MPa to tensile strength sigma r, hardness Hr is that the above resin mother metal 1a of 94 (JIS-A standards) adds than the hard filler of sheave plating layer 2b, the reduction of the coefficient of friction in the time of can suppressing attaching oil, and can realize having the resin-coating cable 3 of the outermost resin 1 of excellent in wear resistance.
So far, adopted the embodiment of thermoplastic polyurethane to be illustrated to resin mother metal 1a, still, resin mother metal 1a not necessarily is confined to thermoplastic polyurethane.As follows, the wear extent of outermost resin 1 is not limited by tensile strength sigma r because of material, therefore, so long as macromolecule elastomer tensile strength sigma r such as alkene system and polystyrene are more than the 25MPa, hardness Hr is more than 94 (the JIS-A standards), the reduction of the coefficient of friction in the time of also can suppressing attaching oil, and can realize having the resin-coating cable 3 of the outermost resin 1 of excellent in wear resistance.
Figure 15 represents the wear extent separately of the thermoplastic polyurethane, benzene series elastomer and the styrene series elastomer that obtain with pin disc type wear test and the relation of their tensile strength sigma r.At this, pin disc type wear test is that benchmark carries out with JIS K7218 (the sliding wear testing methods of plastics).When the state of contact-making surface of this wear test is described with Fig. 1, side will be sold, side will be coiled as sheave plating layer 2b as outermost resin 1.
Show that from Figure 15 these wear extenies tail off when tensile strength sigma r becomes big.And this tendency is that the boundary changes significantly with 25MPa at tensile strength sigma r.This kind that changes macromolecular elastomer all equates.Therefore, learn that under the tensile strength sigma r of the resin mother metal 1a situation lower than 25MPa, the tendency that the wear extent of outermost resin 1 sharply increases is not influenced by material.
Cable of the present invention and band are put down in writing to some extent as lowering or hoisting gears such as being used for elevator, still, are not limited to these purposes, also can be widely used as the cable and the band of taking the weight of.
