Description

Technical Field

[0001] This utility model relates to the field of cable stranding equipment guide roller technology, and more specifically to a cable guide roller device. Background Technology

[0002] Superconducting materials are materials that exhibit zero electrical resistance and repel magnetic field lines under certain low-temperature conditions. When stranding superconducting monofilaments and strands using cantilever twisting machines and cage twisting machines, the superconducting wire is relatively hard and brittle with almost no elongation. This results in stranded superconducting monofilaments and strands that are harder than those made of ordinary materials for the guide rollers. Even with ceramic glazing on the contact surfaces between the guide rollers and the superconducting monofilaments and strands, after a period of use, uneven pits of varying depths will wear down the glazed surface of the guide rollers. When the superconducting monofilaments and strands pass through these pits, the varying depths of the pits can easily scrape off the niobium plating on the surface of the superconducting monofilaments and strands, or even cause them to break. This results in an uneven porosity in the produced superconducting cable, failing to meet the technical specifications for superconducting cables, causing significant waste of superconducting materials, reducing their utilization rate, and increasing the cost of stranding superconducting cables. Utility Model Content

[0003] The purpose of this utility model is to solve the above-mentioned technical problems by providing a wire guide wheel device for stranding superconducting monofilaments and strands using a cantilever single twister and a cage twister.

[0004] To achieve the above objectives, this utility model specifically adopts the following technical solution: a guide wheel device, wherein the guide wheel includes a deep groove ball bearing, two guide wheel plates, two outer end rings, a ceramic ring, and multiple screws and a guide wheel shaft. The two guide wheel plates are detachably connected by multiple screws. The outer side of the deep groove ball bearing is installed on the inner side of the two guide wheel plates, and the inner side of the deep groove ball bearing is fitted with the guide wheel shaft.

[0005] Preferably, both guide wheel plates have an outer end ring on their outer rings, and an annular recess is provided between the two outer end rings. A groove ring is provided on the opposite side of each of the two guide wheel plates, and the opposite side of the two groove rings is connected to the ceramic ring with a clearance fit. A groove surface is provided around the outer ring of the ceramic ring.

[0006] Preferably, each of the two guide wheel plates has a large inner hole on its opposite side, and the opposite side of the two large inner holes is connected to the outer ring of the deep groove ball bearing through a transition fit; each of the two guide wheel plates has a small inner hole on its opposite side, and the two large inner holes and the two small inner holes are interconnected and their center lines coincide.

[0007] Preferably, one of the guide wheel plates has multiple screw holes on its outer side, and the other guide wheel plate has multiple stepped holes on its outer side. The center lines of the screw holes and the corresponding stepped holes coincide, and the screws are installed through the corresponding stepped holes and screw holes.

[0008] Preferably, the outer side of the guide wheel shaft is fitted with two isolation sleeves and two nuts. The isolation sleeves are installed between the guide wheel shaft and the guide wheel plate, and the two isolation sleeves are located on the left and right sides of the deep groove ball bearing, respectively. The two nuts are located on opposite sides of the two isolation sleeves.

[0009] Preferably, a bracket and two nuts are also fitted on the outer side of the guide wheel shaft, with the two nuts located on the left and right sides of the bracket respectively.

[0010] The beneficial effects of this utility model are as follows: By timely replacing the ceramic rings with neat, smooth, and high-hardness edges on the wire guide rollers, it is possible to prevent uneven wear pits on the ceramic-coated surface of the superconducting monofilaments and strands. This avoids the niobium plating on the surface of the superconducting monofilaments and strands from being scraped and the breakage of the stranded superconducting monofilaments and strands. The produced superconducting cable has a uniform porosity, meeting the requirements of the superconducting cable technical specifications. This effectively reduces the serious waste of superconducting materials, improves the utilization rate of superconducting materials, and reduces the cost of stranded superconducting cables.

Detailed Implementation

[0017] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention, but are not intended to limit the present invention.

[0018] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0019] Please see Figure 1-5 The present invention provides the following technical solution: a guide wheel device, the guide wheel includes a deep groove ball bearing 1, two guide wheel plates 2, two outer end rings 3, a ceramic ring 5, and multiple screws 6 and a guide wheel shaft 8. The two guide wheel plates 2 are detachably connected by multiple screws 6. The outer side of the deep groove ball bearing 1 is installed with the inner side of the two guide wheel plates 2, and the inner side of the deep groove ball bearing 1 is fitted with the guide wheel shaft 8.

[0020] The ceramic ring 4 is a hollow cylinder. The outer rings of the two guide wheel plates 2 are each provided with an outer end ring 3, and an annular recess 4 is provided between the two outer end rings. The opposite side of the two guide wheel plates 2 is provided with a groove ring 201. The opposite side of the two groove rings 201 is connected to the ceramic ring 5 with a clearance fit. The outer ring of the ceramic ring 5 is provided with a groove surface 501. The groove surface 501 can be processed into a flat, U-shaped or V-shaped shape according to actual production needs. The groove surface 501 is tightly connected to the joint of the outer end ring 3, and has a smooth transition without burrs.

[0021] Both outer end rings are machined into conical surfaces, which reduces the weight of the guide wheel plate 2 on the one hand, and prevents the superconducting monofilaments and strands that are shaking during stranding from jumping out of the contact surface with the groove surface 501 of the ceramic ring 5, thereby scratching the niobium coating on the surface of the superconducting monofilaments and strands or breaking the stranded superconducting monofilaments and strands; in order to reduce the weight of the guide wheel, both guide wheel plates 2 are machined from aluminum.

[0022] One of the guide wheel plates 2 has multiple screw holes 202 on its outer side, and the other guide wheel plate 2 has multiple stepped holes 203 on its outer side. The center lines of the screw holes 202 and the corresponding stepped holes 203 coincide, and the screws 6 are installed through the corresponding stepped holes 203 and screw holes 202. Except for the different sizes of the stepped holes 203 and screw holes 202, the other dimensions of the two guide wheel plates 2 are exactly the same. One guide wheel plate 2 has multiple screw holes 202 of the same size evenly distributed along its circumference, and the other guide wheel plate 2 has multiple stepped holes 203 of the same size evenly distributed along its circumference. The multiple screw holes 202 are threadedly connected to multiple screws 6. The multiple stepped holes 203 are respectively clearance-fitted with the shank and cylindrical head of the multiple screws 6. By tightening the multiple screws 6, the components of the guide wheel device can be fastened into a whole.

[0023] Each of the two guide wheel plates 2 has a large inner hole 204 on one side facing each other, and the two large inner holes 204 are connected to the outer ring of the deep groove ball bearing 1 through a transition fit. The two guide wheel plates 2 also have small inner holes 205 on opposite sides, and the two large inner holes 204 and the two small inner holes 205 are interconnected and their center lines coincide. The end face formed by the two large inner holes 204 and the two small inner holes 205 limits the axial movement of the outer ring of the deep groove ball bearing 1.

[0024] Two isolation sleeves 7 and two nuts 801 are fitted on the outer side of the guide wheel shaft 8. The isolation sleeves 7 are installed between the guide wheel shaft 8 and the guide wheel plate 2, and the two isolation sleeves 7 are located on the left and right sides of the deep groove ball bearing 1, respectively. The two nuts 801 are located on the opposite sides of the two isolation sleeves 7. By tightening the two nuts 801 that are connected to the external thread of the guide wheel shaft 8, the two isolation sleeves 7 can be fastened in the inner ring of the deep groove ball bearing 1, thereby axially limiting the inner ring of the deep groove ball bearing 1.

[0025] A bracket 9 and two nuts 802 are also fitted on the outside of the guide wheel shaft 8, with the two nuts 802 located on the left and right sides of the bracket 9, respectively. The bracket 9 is fixed in a suitable position on the cantilever single twister and the cage twister. A keyway with clearance fit is machined on the bracket 9 to the external thread of the guide wheel shaft 8. By changing the position of the external thread of the guide wheel shaft 8 in the keyway of the bracket 9, the effective contact surface between the guide wheel device and the superconducting monofilament and strand can be changed. After the external thread of the guide wheel shaft 8 is adjusted to a suitable position, simply tightening the two nuts 802 will ensure the effective contact surface between the guide wheel device and the superconducting monofilament and strand.

[0026] As a further improvement of this utility model, considering that the superconducting monofilaments and strands that vibrate during stranding may sometimes jump out of the contact surface with the groove surface 501 of the ceramic ring 5 and hit the conical surface where the outer end ring 3 is connected to the groove surface 501, the service life of the guide wheel device can be effectively improved by spraying ceramic onto the inner annular recessed surfaces of the two outer end rings 3.

[0027] Working principle and usage process of this utility model:

[0028] 1. Based on the positional dimensions of the bracket 9 of the installed cantilever single twister and cage twister, and the positional dimensions of the guide wheel shaft 8, and in conjunction with the above technical solutions, design a drawing of a wire guide wheel device;

[0029] 2. Based on the design drawings of a wire guide wheel device, and according to the number of guide wheel shafts 8 fastened on the bracket 9 of the cantilever single twister and the cage twister, process each guide wheel plate that meets the actual requirements, purchase multiple ceramic rings 5 ​​that meet the installation requirements, and prepare multiple sets of deep groove ball bearings 1 and multiple screws 6 as required.

[0030] 3. Assemble multiple sets of wire guide roller devices in sequence according to the drawing requirements;

[0031] 4. When the machine is stopped, remove the old parts and tighten the nuts 801 that are connected to the external threads of the guide wheel shaft 8 at both ends of the adjusted bracket 9. This will allow multiple sets of one type of wire guide wheel device to be fastened to the appropriate positions on the guide wheel shaft 8 in sequence, thus ensuring the effective contact surface between the ceramic ring 5 of the guide wheel device and the superconducting monofilament and strand.

[0032] 5. The installation of a wire guide wheel device modified on the cantilever single twister and cage twister is now complete. After all the preparations for starting the machine are completed, it can be started normally.
