Description

Technical Field

[0001] The invention belongs to the technical field of friction and wear between shaft sleeves and linings at both ends of a hot-dip galvanized sinking roller, and in particular relates to a roller end shaft sleeve, a lining assembly and a supporting structure. Background Art

[0002] At present, the wear between the sleeve and the lining is an important reason affecting the stability of the sinking roller system and the length of the online cycle of the galvanizing line. The corrosion of zinc liquid on rollers, bearings, strip steel, etc. produces zinc slag, some of which floats on the top layer, some is suspended in the middle, and some sinks to the bottom of the zinc pot.

[0003] During the rotation of the sunken roller, the sleeves at both ends rotate, while the linings at both ends that support the sleeves are fixed. During operation, the zinc slag produced by the high-temperature zinc liquid enters the gap between the sleeve and the lining to act as a lubricant to reduce friction. However, after a long time, the zinc slag will continue to accumulate between the sleeve and the lining and affect the rotation of the sleeve. At this time, the zinc slag needs to be discharged. Therefore, there is an urgent need for a roller end sleeve, a lining assembly, and a support structure formed by the two, which can achieve the functions of reducing friction and drag, slag holding and slag discharge. Summary of the invention

[0004] The problem to be solved by the present invention is to provide a roller end sleeve, a lining assembly and a support structure for a hot-dip galvanizing line, which realizes wear and drag reduction and slag holding and discharge between the support structures by means of a roller end sleeve with a spiral groove and a V-shaped lining with a slag holding groove.

[0005] The invention discloses a roller end sleeve for hot dip galvanizing line. The outer wall of the roller end sleeve is provided with a plurality of spiral grooves, the spiral grooves are evenly distributed along the circumference of the outer wall of the sleeve, the two ends of the spiral grooves are connected with the two end surfaces of the sleeve, and the rotation direction of the spiral grooves is the same as the rotation direction of the roller end sleeve itself.

[0006] Furthermore, each spiral groove has the same shape and size, and the cross section of the spiral groove is triangular, and the size of the cross section gradually increases from the inner end to the outer end of the roller end sleeve.

[0007] The present invention discloses a lining tile assembly for a hot-dip galvanizing line, which comprises a V-shaped lining tile, a lining tile cushion block and a lining tile mounting seat; an open through groove is provided at the bottom of the lining tile mounting seat, the V-shaped lining tile is fixed in the open through groove, and the V-shape of the upper part forms two symmetrical shaft sleeve contact surfaces on the left and right sides, a slag containing groove is provided between the two shaft sleeve contact surfaces on the left and right sides, and the slag containing groove is an open structure; the lining tile cushion block is fixed at the lower part of the open through groove and is fixedly connected with the V-shaped lining tile.

[0008] Furthermore, the inner side of the lining tile mounting seat is wedge-shaped: that is, it gradually expands from bottom to top to the center, and gradually expands from the inside to the outside.

[0009] The invention discloses a support structure for hot-dip galvanizing line, which comprises a roller end sleeve and a lining shoe assembly. The outer wall of the roller end sleeve is provided with a plurality of spiral grooves, and the outer wall of the roller end sleeve is in line contact with two symmetrical sleeve contact surfaces of a V-shaped lining shoe.

[0010] Furthermore, at every moment when the roller end sleeve rotates, at least one spiral groove passes through the contact line between the roller end sleeve and the V-shaped lining shoe.

[0011] Furthermore, the hardness of the roller end sleeve and the V-type lining shoe is substantially the same.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] Example 1

[0021] from Figure 1 , Figure 2 It can be seen that the present invention is a roller end sleeve for a hot-dip galvanizing line: a plurality of spiral grooves 2 are provided on the outer wall of the roller end sleeve 1, the spiral grooves 2 are evenly distributed along the circumference of the outer wall of the sleeve 1, the two ends of the spiral grooves 2 are connected to the two end surfaces of the sleeve 3, and the rotation direction of the spiral grooves 2 is the same as the rotation direction of the roller end sleeve 1 itself.

[0022] The spiral groove 2 is grooved on the outer wall of the roller end sleeve 1 by using surface texturing technology, which improves the friction and wear performance of the friction pair formed by the roller end sleeve 1 and the lining assembly. The rotation direction of the roller end sleeve 1 depends on the direction of rotation of the roller and the flow direction of the zinc liquid near the bearing when the groove is not opened; the rotation direction of the spiral groove 2 is consistent with the rotation direction of the roller end sleeve 1, ensuring that the zinc slag is discharged with the rotation of the roller end sleeve 1. The two ends of the spiral groove 2 are connected to the two end surfaces of the sleeve 3, ensuring that the zinc slag is discharged from the inside of the sinking roller to the two ends.

[0023] Example 2

[0024] from Figure 1 , Figure 2 It can be seen that in the roller end sleeve of the present invention, each spiral groove 2 has the same shape and size, the cross section of the spiral groove 2 is triangular, and the size of the cross section gradually increases from the inner end to the outer end of the roller end sleeve 1.

[0025] The cross section of the spiral groove 2 is triangular, which can accumulate zinc slag, i.e., contain slag; the size of the cross section gradually increases from the inner end to the outer end of the roller end sleeve 1, so that the zinc slag can be easily discharged from the inside to the outside, i.e., slag discharge.

[0026] Example 3

[0027] from Figure 1 , Figure 3 , Figure 4 , Figure 5 It can be seen that the present invention is a lining tile assembly on a hot-dip galvanizing line: it includes a V-shaped lining tile 3, a lining tile pad 5, and a lining tile mounting seat 6; an open through groove is provided at the bottom of the lining tile mounting seat 6, the V-shaped lining tile 3 is fixed in the open through groove, and the V-shape on its upper part forms two symmetrical left and right sleeve contact surfaces, and a slag containing groove 4 is provided between the left and right sleeve contact surfaces, and the slag containing groove 4 is an open structure; the lining tile pad 5 is fixed at the lower part of the open through groove and is fixedly connected to the V-shaped lining tile 3.

[0028] The slag containing groove 4 makes the zinc slag have no closed space for accumulation, so that the flow field between the roller end sleeve and the V-type lining is relatively uniform, and it is not easy for hard zinc slag to be deposited in the gap between the sleeve and the V-type lining, which is conducive to the discharge of zinc slag.

[0029] Example 4

[0030] from Figure 1 , Figure 5 It can be seen that in a lining tile assembly of the present invention, the inner side of the lining tile mounting seat 6 is wedge-shaped, that is, it gradually expands from bottom to top to the center, and gradually expands from the inside to the outside.

[0031] The mounting seat 6 gradually expands from bottom to top and from inside to outside, so that there is no closed space for zinc slag to accumulate between it and the roller end sleeve, which is conducive to the discharge of zinc slag.

[0032] Example 5

[0033] from Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 It can be seen that the present invention is a support structure for hot-dip galvanizing line: it includes a roller end sleeve 1 and a lining assembly, a plurality of spiral grooves 2 are provided on the outer wall of the roller end sleeve 1, and there is line contact between the outer wall of the roller end sleeve 1 and the two symmetrical sleeve contact surfaces of the V-shaped lining 3.

[0034] The spiral groove 2 is grooved on the outer wall of the roller end sleeve 1 by using the surface texturing technology, which improves the friction and wear performance of the friction pair formed between the roller end sleeve 1 and the V-type bushing 3, and achieves wear and drag reduction. The line contact between the V-type bushing 3 and the sleeve 1 reduces the contact area between the V-type bushing and the roller end sleeve 1 or related parts, thereby effectively reducing the friction force, achieving wear and drag reduction, and ensuring the stability of the roller operation.

[0035] Example 6

[0036] from Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 It can be seen that in a supporting structure of the present invention, at every moment when the roller end sleeve 1 rotates, there is at least one spiral groove 2 passing through the contact line between the roller end sleeve 1 and the V-shaped lining 3.

[0037] At every moment when the roller end sleeve 1 rotates, there is at least one spiral groove 2 passing through the contact line between the roller end sleeve 1 and the V-shaped lining bush 3, so that when the sinking roller rotates, impurities in the liquid, such as zinc slag in zinc liquid, flow out from the gap between the roller end sleeve 1 and the V-shaped lining bush 3 along the spiral groove, thereby preventing the impurities from affecting the rotation between the sleeve and the bearing bush.

[0038] Example 7

[0039] A supporting structure of the present invention: the hardness of the roller end sleeve 1 and the V-shaped lining 3 are substantially the same.

[0040] The hardness of the roller end sleeve 1 and the V-type lining 3 is substantially the same, so as to prevent the performance of the friction pair from being affected due to severe wear on one side.

[0041] The advantages of the roller end sleeve, lining shoe assembly and supporting structure for hot-dip galvanizing line of the present invention are as follows: 1. The outer wall of the roller end sleeve is provided with a spiral groove, and the friction and wear performance of the friction pair formed by the roller end sleeve and the lining shoe assembly is improved by using the surface texturing technology, thereby achieving wear and drag reduction; the rotation direction of the spiral groove is consistent with the rotation direction of the roller end sleeve, thereby ensuring that the zinc slag is discharged with the rotation of the roller end sleeve; 2. The cross section of the spiral groove is triangular, which can accumulate zinc slag, i.e., contain slag; the size of the cross section gradually increases, so that the zinc slag can be conveniently discharged from the inside to the outside, i.e., Slag discharge; 3. A slag containing groove is opened on the V-shaped liner, and hard zinc slag will not be deposited in the gap between the sleeve and the V-shaped liner, which is conducive to the discharge of zinc slag; 4. The line contact between the V-shaped liner and the sleeve effectively reduces the friction and achieves wear and drag reduction; 5. At every moment when the roller end sleeve rotates, there is at least one spiral groove passing through the contact line between the roller end sleeve and the V-shaped liner, so that when the sinking roller rotates, impurities in the liquid flow out from the gap between the roller end sleeve and the V-shaped liner along the spiral groove, avoiding impurities affecting the rotation between the sleeve and the bearing.

[0042] In conclusion, the present invention can effectively reduce the zinc slag wear between the roller end sleeve and the lining shoe assembly, achieve wear and drag reduction, slag holding and slag discharge, and achieve the stability of the submerged roller system.
