Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a support disk and a support device for supporting an open-type textile cup, relating to a support disk and an open-type spinning device having the support disk of the present invention. [Prior Art] It is known to support an open woven cup by a shaft and by means of a support disk. In this regard, two pairs of support discs are generally used, which support the shaft of the textile cup in its wedge-shaped gap, that is, a pair of support discs support their rotation shafts near the textile cup, and a pair of support discs support them at one end away from the spinning cup. Rotating shaft. When the open-type spinning device is operated, the rotating shaft of the spinning cup rolls on the rolling surface of the supporting disk. Thus, the shaft of the spinning cup is in line contact with the rolling surface of the support disc rim. The open spinning cup can be driven by its shaft and by means of a tangential belt provided between the pair of support discs. A support device for an open spinning cup is known from DE 37 24 5 45 A1. The rolling surface of the support disk has cooling grooves or grooves which are identical to the support of the open spinning cup used in US-P 5,1,8,4,7 3 . A tray includes a substrate covered with a rolling layer. Its rolling layer constitutes a rim and has a rolling surface on its outer circumference. The rolling layer is made of plastic, which guarantees the smooth rolling of the open spinning cup. When operating, its rolling layer facilitates the damping of the spinning cup and the smooth running of the spinning machine. Since the rotating shaft rolls on the rolling surface of the support disk, it generates heat and damages it. This is caused by overheating of the rolling layer of the support disk. In addition to rolling surfaces such as ribs of another type, US-P 5,178,473 discloses a cooling groove formed on the rolling layer of the support disk. The cooling slot actually

Page 4 1274795 V. Inventions (2) are used on all. DE 195 rim and its base groove, but its DE 197 has a spiral-shaped open-vehicle rolling surface from the slot-shaped break line, which is the same as the support disk 49 used on or in the support device of the open textile machine of the embodiment. 46 6 There may be 12 916 grooves between the bodies, so that the two or cup support groove breaks are broken multiple times. A connection is disclosed in a real A 1 . One or more cold notches as shown. Therefore, one side of the rolling layer is distributed to the other side of the open matrix of the read-matching bit, but they are not associated with the DE 197 disk, wherein the rolling zone's thickness of the base rolling layer can be too large to be too large on the outer surface. It will give its circumference a distribution of 1 9 7 9 1 by two recesses with a deep and uniform formation of the groove enough to prevent the A 1 from being disclosed. Thus, a plurality of groove devices are used as the material of the cleaning solution and the grooves are formed from the same groove as shown in Fig. A1, and the thickness of the layer is thicker than that of the layer, and the actual groove is rolled. . EP among them is a washing tank. The support disk of the support disk is grooved. The support disc, the same as its support 0960963, the retainer has a base which is shown to be sufficiently thick. On the other side, it is difficult to have two slots. A kind of open. This notch fits several times. . Since the layer is produced to the side of the DE 197-shaped notch (the base body, which facilitates the movement of the contact plate on the moving surface without the cooling of the rotating shaft on the rotating surface of the shaft A 2 discloses a groove-shaped fracture of the cleaning tank The non-washing area has a recess from the support disc, which is referred to in Fig. 1) due to the support of the support disc support device, and the ribs of the rolling layer are entrapped in the grooved area of the rolling layer. . It is such that the recess in the base body can dissipate the heat between the rolling surface and the rolling surface of the rolling surface from the base body into the base body.

Page 5 of 1272495 V. INSTRUCTIONS (3) In addition, the base body and the rolling over the minimum surface time base are provided with a plurality of grooves, and the rolling surface is less. DE 197 56 71 The rolling surface has a fixed wheel gallery 'It has an outer portion, and the embodiment is still at a high rotation speed. SUMMARY OF THE INVENTION The support disk of the object of the present invention is constituted by having the same body on the width of the substrate, and is formed in the same manner as the base body. Pick up. The object of the present invention is achieved. According to the present invention, there is a stacking of 0. 5 material having a contoured distance on the outer circumference of the support disk rim, i.e., the groove depth (T), thereby reducing the knot of the present invention.

The moving layer is only contacted by a small surface, and its surface is raised only by the two grooves on the body. Try to ensure the cooling of its rolling layer by rolling the layer. The second groove is also depressurized, thereby hoping to increase its service life. 1 C 2 discloses a support disc of a different field, in a groove having only a cooling effect. The support disk has a V-shaped central structure and side ribs on the base. Here, heat is dissipated from the rolling layer, but there is a problem of fixing and heat dissipation. It is to provide a cooling groove formed on a rolling layer having a plurality of groove rolling layers and to sufficiently cool the heat dissipation layer while its rolling layer is substantially at a full thickness and thus has a cushioning property. In addition, when the base spinning cup and the support disc rotate at a high speed, the rolling layer is ensured to be a supporting disc of the structure through the supporting disc and the supporting device of the open spinning cup, which has a base body and a base body which is radially spaced from the groove-shaped fracture region. The area outside the fracture surface of the rolling surface is large, and the thickness of the rim layer between the contour and the rolling surface is between 2.5 and 5 times, thereby avoiding the heat of the small rolling layer of the rolling sheet supporting the disk load. The support plate is realized in addition to passing through the rim layer

Page 6 1274795 V. INSTRUCTIONS (4) The groove cools the rim, and sufficient heat is dissipated from the rolling layer by contact with the substrate. Furthermore, it is simultaneously achieved that the rim has a sufficiently uniform thickness sufficient to cushion the shaft of the spinning cup and thereby improve the rolling. In addition, it is advantageous that the profile ensures that the contact area of the base body with the rim is sufficiently large that the rim does not disengage from the base of the support disc under severe operating conditions and when the support disc rotates at a high speed. 5之间之间。 Between 0. 5至1. 0倍之间。 The thickness of the rim of the rim. Thus, the buffering of the layers can be adjusted as needed by the range of values. The thickness dimension of the rim is obtained by a beneficial contour structure having three lobed configurations, while the manufacturing cost of the substrate can be reduced by means of no-cut forming such as extrusion. The beneficial structure of the basic body, i.e. the outer configuration of its profile, transitions into a rear cut such that its profile is laterally sandwiched by the rim, thereby ensuring a secure connection between the rim and the base. In another advantageous configuration of the invention, the profile is comprised of three lobed configurations wherein the rim thickness in the central configuration region is less than the rim thickness of the outer lobed configuration region. This ensures that in the region of the rolling surface where the temperature peak occurs, heat is easily dissipated to the substrate. By the π-uplift π-type structure, the thickness of the rolling layer is thinned at a position where the heat load is large. In a particularly advantageous construction of the invention, the base body of the support disc, in particular its contour, is at least partially formed by the extruded base body. Thereby, the cost of the substrate can be lowered and the manufacturing can be repeated with high precision. The support device for the open-type spinning cup of the present invention can be constructed such that the open-type spinning cup device is provided with the support disk of the present invention. This results in a support device that can operate under high speed rotation. In order to further understand the features and technical contents of the present invention, please refer to

[Implementing the genre J, please refer to Figure 1, the sister-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- i ± The support members 1 2 are respectively provided with shafts 1 3, each of which is connected to the support disk 14 by its respective side ends. The support discs 14 are respectively formed by two pairs of support discs to form two wedge-shaped gaps 141. The support sleeve 14 is provided with a sleeve 2 1 of an open spinning cup t. If its open-type spinning cup 2 is swayed, for example by a tangential belt (not shown), it rolls in the wedge-shaped gap 141 formed by the support disk 14. Thereby, it is in a rotating state. The support discs 14 each have a two-divided fracture 3, a groove or groove known to those skilled in the art. The support device 1 of Fig. 1 has two groove-shaped fractures 3 on all four support disks 4, respectively. It is also conceivable to provide a groove-shaped fracture 3 for a support disk 14 which forms each of the wedge-shaped gaps 141. The shaft turns 3 are not parallel to each other in a known manner, but are inclined to each other such that an axial thrust is applied to the shaft through the support disk. Its shaft is supported in the axial thrust bearing 1 以 in a known manner. The bearing can be, for example, a hemispherical bearing or an air static axial thrust bearing as shown in the embodiment of Fig. 1. Due to the inclined state of the shaft yoke 3, heat is also generated on the rolling surface 41 of the rim 4 of the support disk 14 due to friction (see Fig. 2). The support disk supporting device is constructed as an embodiment, which is suitable for each An order of magnitude of 150,000 rpm. The diameter of the shaft is 8 mm and the diameter of the support disc is 78 mm. The thickness of its rim layer matches its outer diameter.

According to the invention, its base 5 has a profile 6, which consists of three petal configurations 6丨. The thickness of the rim* in the mid-soil configuration 61 region is smaller than the thickness of the outer lobed configuration 6 丨 region. The advantage is that the area of the rim 4 with the hottest heat can pass better through the contours. Its heat transfer passes through the rim 4 at a shorter distance, and is better. 7 According to experience, some of the rolling surfaces on both sides of the rolling surface will not report the heat, because they will be better cooled by the natural environment. ° ^

As shown in Figure 2, the trailing slit 62 of the profile 6 is located below the left and right petal configuration η. Thereby, the rim 4 encloses the configuration 61 so as to be connected in a radial direction, which ensures that the rim 4 is better fixed to the base 5. Beneficial \ The package appears in areas where the heat load is lower than the middle of the contour. = 疋 profile 6 has a larger surface defined by three lobed configurations 61, ', : ferrule 4 and base 5 that facilitate good contact between the rim 4 and the substrate 5 material, while ensuring Good connection between. Its slot 3 (groove branch - in Figure 2 is the cooling slot, however it can also be a cleaning slot with its rolling surface 41:

The right-angled groove-shaped fracture (groove) 3 is also replaced by a wedge opening/groove for the base body 5 which is cut away in Fig. 2 . For the sake of the description, the rim 4 that was cut open did not use the cross-sectional line table. And for the sake of clarity, as with the other parts of the base body 5, the wheel can be omitted from the main 祁6 by means of extrusion. The reduction of the depth τ of the support disk into the groove-shaped fracture 3 is the prior art, but the officer of the groove 3 is fed from a/wood degree' and the visibility of the cold p-tank 3 is generated by its material and according to the need. The shape of the 'petal configuration 61' is so determined, and it is true. The same can not significantly weaken the petal configuration of the six-sentence structure,,,, and at the same time, the sedimentary layer between the i and the rim, and the material of the rim 4 that is necessary. The rolling surface 4 1 is formed. Fig. 3 shows the right green-丄 diagram of the support tray 14 of the present invention. The outer 2 2 rims 6, of the base 5, are formed by the underside of the three lobed configuration 61, the contours of which are contoured by the left and right lobes and sandwiched in the base 5. Gold, the rim 4 is raised in the direction of the rolling surface 41 in the direction in which the rim 4 is compared with the base of Fig. 2, and the #μ _ region 51 is raised.
