Description
Technical field
The present invention relates to the parts of loom, it is with the interconnective structural element that can be moved each other by axle.
Background technique
Known dissimilar loom.Spinning Machinery, weaving machine and knitting machine is exemplarily listed at this.
Warp knitting machine is such as used to produce knitted fabric.Warp knitting machine all has knitting needle and sley point (Legenadel), and it moves relative to each other, to form coil.In order to produce this relative movement, need supporting element and transmission component.They are below also referred to as structural element.So usually these structural elements to be summarized in the parts of loom.Structural element relative movement each other not only can translation motion exist, and can rotary motion exist.If rotary motion, so usually moment of torsion must be delivered to another structural element from a structural element.
Run with relatively very high operating rate at this warp knitting machine exemplarily discussed.This causes the desired very high productivity of warp knitting machine.But warp knitting machine runs with very high operating rate and can cause producing relatively a large amount of waste heats.Waste heat is produced by energy ezpenditure (such as rubbing).Therefore in the surrounding environment of machine, inevitably there is temperature gradient when loom runs.At that time, temperature gradient can cause the thermal expansion in various degree of the structural element of loom.But this type of thermal expansion in various degree not wishing structural element, because it can cause the problem of the smoothness of operation with loom.
Summary of the invention
Therefore, the object of the invention is to ensure that the parts of loom run reliably when there is temperature difference.
This object is so solved by the parts of the loom starting the type mentioned, namely axle has: shroud, and it is with internal diameter and external diameter; With enhancing element, it is with the thermal expansion coefficient less than shroud, and wherein, strengthens element and be fixed on shroud place in the region of internal diameter.
Strengthen planning and be fixed on its shroud place within axle.Strengthen element and there is the thermal expansion coefficient less than shroud.When axle place exists temperature gradient, not only shroud but also enhancing element expand under its effect corresponding to its material behavior.But, because strengthen element to be provided with less thermal expansion coefficient than shroud, thus draw strengthen the length of element or volumetric expansion less.Meanwhile, strengthen element but be still fixed on shroud place in the region of internal diameter.Shearing stress can be there is thus between enhancing element and the shroud of axle.But shearing stress is fixed on shroud place to bear in the region of internal diameter by strengthening element.Therefore, can not show that the thermal expansion of shroud is greater than the thermal expansion strengthening element.Heat-staple axle to a great extent can be established thus by the thermal expansion coefficient correspondingly coordinating to strengthen element and shroud.This is not only applicable to outside temperature gradient, and is applicable to inner temperature gradient.Outside temperature gradient is understood as rising or the decline of the ambient temperature of axle at this.Inner temperature gradient represents the region of the different temperatures in axle or rather its shroud itself.
Strengthen element preferably to extend in the circumferential direction of internal diameter along the axial extension part of shroud.Therefore strengthen planning and be fixed on shroud place in the whole length of the axial extension part of shroud.Strengthen the inwall lining illustrated by internal diameter that element is entirely shroud equally.Thus can by axle or rather the thermal expansion of its shroud in its whole size correspondingly keep very little or suppress thermal expansion completely.Can realize strengthening element to be equally arranged in symmetrically to a great extent within axle, can the impact of enhancing element on the kinetic characteristic of axle be kept very low thus.Keep very little by producing not round risk.
The radial extension part preferably strengthening element is configured to the radial extension part being less than shroud.Obtain the possibility of the joint space-efficient mode of structure according to axle of the present invention thus on the one hand.On the other hand, in order to reach desired technique effect, the enhancing element with very little radial extension part only must be provided.At this, but necessarily design strengthens the radial extension part of element, and namely it can bear the shearing stress that the thermal expansion due to the shroud of axle occurs, and making it fixedly unclamp at this.Thus can simply and the mode of cost advantages strengthens the manufacture of element accordingly.
In addition, the body material (Matrixwerkstoff) that element is connected with shroud with having material fit is preferably strengthened.Therefore, the material fit strengthening the body material of element is used for enhancing element to be fixed on shroud place in the region of internal diameter.
Set material fit can two types realize.A kind ofly on the body material strengthening element, application can set up the material of the connection of material fit.Can be such as tackiness agent at this this material.But another kind can be arranged to body material itself equally and set up material fit with shroud.Finally also can be arranged to strengthen element be connected with shroud via other fixing type and mode material fit by its body material.Such as, the connection by friction welding can be should be mentioned that at this.
At this, preferably body material is configured to the tackiness agent of cold hardening.The tackiness agent of cold hardening is therefore for the connection of the material fit between body material and shroud.But, in this embodiment, except body material, can abandon can ensureing other compositions with the material fit of shroud for strengthening element interpolation.In addition, the tackiness agent of cold hardening simplifies the manufacture according to axle of the present invention.What should maintain when manufacturing axle can room temperature determine to fixed temperature, is namely such as specified to 18-25 DEG C.Therefore significantly simplify the manufacture of axle, because need not a large amount of manufacturing steps be carried out, such as, add at axle and man-hour it is heated.
Preferably, body material is configured to epoxy resin.But, equally such as can use polyester or polyamide.
It is also preferred that strengthening element has the unidirectional reinforcing fiber stretched on the axial direction of shroud, it is embedded in body material.Reinforcing fiber bears such task at this, namely bears when there is temperature gradient and offsets the shearing stress of axle.Therefore, strengthen element and there is the reinforcing fiber be embedded in body material.Strengthen element can seem thus to be configured to fiber-reinforced plastics.Reinforcing fiber stretches on the axial direction of shroud at this, because reinforcing fiber must bear the shearing stress of shroud in the direction in which, can resist the length expansion of the heat of shroud.Therefore, reinforcing fiber preferable configuration is in the whole axial extension part strengthening element or shroud.
At this, preferably reinforcing fiber comprises carbon, glass or aramid fiber (Aramid).These materials confirm to realize desired technique effect.
Preferably, reel structure is link type carrying axle (Hebeltragwelle).
Preferably, piece construction is for knitting elements carrying sley bar
rod-type assembly.
Accompanying drawing explanation
By preferred embodiment, the present invention will be described by reference to the accompanying drawings below.Wherein:
Fig. 1 shows the cross section according to axle of the present invention.
Embodiment
Fig. 1 shows the cross section of axle 1 with schematic diagram.At this, axle 1 has shroud 2.Strengthen element 3 arrange and be fixed in the region of the internal diameter of shroud 2.
This type of axle 1 can manufacture with different types and mode at this.Tackle a kind of possibility to be below described.First core (Hilfskern) will be assisted to be incorporated in flexible Cylindrical object (such as flexible pipe).Flexible Cylindrical object is made to stablize thus.In next step, one-way fabric comprising reinforcing fiber is enclosed on flexible Cylindrical object.This fabric such as can comprise carbon fiber reinforced plastics.Then tackiness agent is utilized to infiltrate one-way fabric.Tackiness agent such as can construct to cold hardening.Can realize thus being predetermined to be production close to carrying out axle 1 room temperature (i.e. such as 20-22 DEG C) in temperature.Then auxiliary core is incorporated in the shroud 2 of axle 1.Shroud 2 such as can comprise metallic material, such as steel.Once flexible Cylindrical object is brought in shroud 2 in its final position, just for it loads air.This causes the expansion of flexible Cylindrical object.By expanding, the one-way fabric utilizing tackiness agent to infiltrate is contacted with the inner side of shroud 2.Tackiness agent can be allowed now to harden and therefore produced enhancing element 3 can be fixed on shroud 2 place.Connect shroud 2 by utilizing tackiness agent to block with the direction that enhancing element 3 makes axle 1 pass through used reinforcing fiber when temperature raises.
Strengthen element 3 as can be seen from Figure 1 to construct in the whole circumferential direction of the internal diameter of shroud 2.Strengthen element 3 to extend along the axial extension part of shroud 2 equally.Preferably be arranged on the unidirectional reinforcing fiber strengthened in element 3 to stretch on the axial direction of shroud 2, namely stretching perpendicular on the direction of plotting planes in FIG.Reinforcing fiber can bear the power along its longitudinal extension part.For axle 1 shown in Figure 1, its shearing stress that therefore can bear shroud 2 and strengthen between element 3.Therefore the thermal expansion of shroud 2 on the axial direction of axle 1 is prevented largely by strengthening element 3.
From Fig. 1, can find out that axle 1 according to the present invention has equally strengthen element 3, its radial radial direction being less than shroud 2 that extends extends.Manufacture axle 1 with obtaining cost advantages thus, because the material for strengthening element 3 can be saved.Reduce the advantage for the possibility of the material strengthening element 3 with other.Therefore can realize strengthening element 3 equally constructs very light compared with the shroud 2 of axle 1.Therefore, the enhancing element 3 of existence only affects the kinetic characteristic of axle 1 a little.Axle 1 can be made with very little weight equally.As shown in Figure 1, axle 1 can be configured to hollow shaft.Axle 1 can mixed construction mode (Hybridbauweise) manufacture.
Utilize and can provide heat-staple axle 1 without problems according to axle 1 of the present invention, it has the thermal expansion being reduced to 1/10 compared with not strengthening the axle of element 3.The axle 1 almost no longer with thermal expansion is can be made into when corresponding accurate adjustment.
