[0002] One end of the roller in the rolling mill can be mounted on the bearing seat through a bearing, and the bearing seat is supported in the window provided in the arch of the rolling mill. Because the arch and the bearing seat will have impact and friction with each other during the operation of the roller, a lining plate is added between the bearing seat and the window of the arch.

As a result, the rolling mill needs to frequently replace the liner or adjust the roller position, resulting in frequent maintenance of the rolling mill and high maintenance costs.

[0036] The present application will be described below with reference to the accompanying drawings:

[0037] Figure 1 A schematic structural diagram of a bearing seat assembly in some embodiments or certain embodiments of the present application is shown, with reference to Figure 1 An embodiment of the present application provides a bearing seat assembly, including a bearing seat body 1, a first lining plate 2 and a protective component 3.

[0038] The bearing seat body 1 includes two side portions 11 and a top portion 12 connecting the two side portions 11 . The top portion 12 has two mounting surfaces 121 spaced apart from each other and respectively connected to the two side portions 11 .

[0039] The two first lining plates 2 are detachably connected to the two side portions 11 .

[0040] The two protective components 3 are respectively arranged on the two mounting surfaces 121 of the top 12. The protective components 3 include an elastic protective layer 31 placed on the corresponding mounting surface 121 and a pressing part 32 for pressing the elastic protective layer 31. The elastic protective layer 31 protrudes from the side 11 corresponding to the mounting surface 121, and the maximum distance between the two elastic protective layers 31 is greater than the maximum distance between the two first lining plates 2.

[0041] In the bearing seat assembly, the two side portions 11 of the bearing seat body 1 can be detachably connected to the corresponding first lining plate 2. When the bearing seat body 1 is installed in the arch 100 of the rolling mill, the first lining plate 2 can reduce the wear rate of the bearing seat body 1. A top 12 is connected between the two side portions 11 of the bearing seat body 1. The top 12 has two mounting surfaces 121 that are spaced apart from each other and respectively connected to the two side portions 11. The position is close to the two side portions 11 of the bearing seat body 1, that is, closer to the contact position between the first lining plate 2 and the arch 100 of the rolling mill. The two protective components 3 are respectively arranged on the two mounting surfaces 121 of the top 12, and the protective components 3 include an elastic protective layer 31 placed on the corresponding mounting surface 121, and a pressing member 32 for pressing the corresponding elastic protective layer 31 on the mounting surface 121, which can facilitate the elastic protective layer 31 to protect the first lining plate 2 and the contact area between the first lining plate 2 and the arch 100. Each elastic protective layer 31 protrudes from the side 11 corresponding to the mounting surface 121 on which it is located, and the maximum distance between the corresponding elastic protective layers 31 in the two protective components 3 is greater than the maximum distance between the two first liners 2. Then, when the two first liners 2 of the bearing seat body 1 are in contact with the arch 100 respectively, the elastic protective layer 31 pressed on the corresponding mounting surface 121 will also be in direct contact and extrusion with the arch 100. The first liner 2 can be located under the corresponding elastic protective layer 31, reducing the probability of lubricating oil or iron sheet entering between the first liner 2 and the window 1001 of the arch 100, reducing the possible impact of impurities on the first liner 2, extending the normal working time of the first liner 2, and reducing the possibility of the installation position accuracy of the roller 200 being affected. It can reduce the frequency of maintenance of the first liner 2 and the frequency of adjustment of the position of the roller 200, and to a certain extent solve the technical problem of frequent maintenance and high maintenance cost of the rolling mill.

[0042] When the bearing seat assembly provided in this application is installed on the arch 100, it can reduce the impact on the first lining 2 while also reducing the impact on the arch 100 and the window 1001 of the arch 100. It is also beneficial to reduce the possibility of the arch 100 needing to be cleaned and maintained, thereby improving the operating reliability of the rolling mill.

[0043] Figure 2 A top view of a protective component 3 in some embodiments or certain embodiments of the present application is shown, with reference to Figure 2 It can be seen that in some or certain embodiments, the elastic protective layer 31 is in a rectangular parallelepiped shape, and the two elastic protective layers 31 are provided with rounded corners on the sides away from each other.

[0044] The elastic protective layer 31 is in the shape of a rectangular parallelepiped, which facilitates the installation of the elastic protective layer 31 on the bearing seat body 1. The two elastic protective layers 31 are provided with rounded corners on the side away from each other. The rounded corners can facilitate the disassembly and assembly of the elastic protective layer 31, ensuring the protective effect of the elastic protective layer 31 on the first lining 2 while reducing the possibility of interference between the elastic protective layer 31 during disassembly and assembly.

[0045] Figure 2 The roller neck 2002 of the roller 200 is also shown.

[0046] In some or certain embodiments, the bearing seat body 1 is further provided with a mounting hole 15 extending along its own length direction and located between the two side portions 11, the length L2 of the elastic protective layer 31 extends along the length direction of the mounting hole 15, and the length L2 of the elastic protective layer 31 is greater than the length L of the bearing seat body 1.

[0047] The bearing seat body 1 is also provided with a mounting hole 15 extending along its own length direction and located between the two side portions 11. The mounting hole 15 can be used to install the rolling roller 200. The two side portions 11 can also be supported and contacted through the corresponding first lining plate 2 and the window 1001 of the arch 100, so that the length L2 of the elastic protective layer 31 extends along the length direction of the mounting hole 15, and the length L2 of the elastic protective layer 31 is greater than the length L of the bearing seat body 1. When the elastic protective layer 31 is installed to the mounting surface 121 of the top 12, the elastic protective layer 31 has a margin in the length direction and can protrude from the bearing seat body 1. It can also reduce the probability of mixed impurities such as lubricating oil and iron sheets entering between the first lining plate 2 and the window 1001 of the arch 100, and reduce the possible impact on the first lining plate 2 and the arch 100, which is conducive to extending the normal working time of the first lining plate 2 and the arch 100, and reducing the required maintenance frequency and maintenance cost.

[0048] In some or certain embodiments, both ends of the elastic protective layer 31 in the longitudinal direction may protrude from the bearing seat body 1. This can effectively reduce the probability of mixed impurities such as lubricating oil and iron sheets entering between the first lining plate 2 and the window 1001 of the arch 100, thereby reducing the potential impact on the first lining plate 2 and the arch 100, thereby increasing the service life of the first lining plate 2 and the arch 100 and reducing the required maintenance frequency and maintenance costs.

[0049] In some or certain embodiments, the top portion 12 further includes a transition surface 122 and two inclined surfaces 123, with both sides of the transition surface 122 connected to the mounting surface 121 via the two inclined surfaces 123. The bearing seat body 1 may also include a bottom portion 13 spaced apart from the top portion 12 and connecting the two side portions 11. Depending on requirements, the bottom portion 13 of the bearing seat body 1 may or may not be provided with a protective assembly 3. It should be noted that when the bearing seat assembly is installed in a rolling mill, the top portion 12 of the bearing seat body 1 may be higher than the bottom portion 13 of the bearing seat body 1. The top portion 12 may also include a convex curved surface, with both sides of the curved surface connected to the two mounting surfaces 121.

[0050] In some or certain embodiments, the elastic protective layer 31 is an anti-corrosion elastic protective layer 31. This can increase the service life of the elastic protective layer 31. The elastic protective layer 31 has a long service life, and the elastic protective layer 31 can protect the first lining plate 2 for a longer period of time, thereby increasing the service life of the first lining plate 2 and reducing the maintenance frequency required for the first lining plate 2 and the archway 100.

[0051] In some or certain embodiments, the elastic protective layer 31 may be a wear-resistant and corrosion-resistant colloid elastic protective layer 31. The elastic protective layer 31 has a long service life, which is conducive to extending the working time of the first lining plate 2.

[0052] In some or certain embodiments, the ends of the elastic protective layer 31 may also be flush with the ends of the bearing seat body 1. The shape of the elastic protective layer 31 may also be trapezoidal or irregular, and the elastic protective layer 31 may be a rubber elastic protective layer 31. This can also extend the normal working time of the first lining plate 2.

[0053] In some or certain embodiments, the bearing seat body 1 further includes at least two rod portions 14 provided on each mounting surface 121 , and the elastic protective layer 31 and the pressing member 32 are sequentially sleeved on the at least two rod portions 14 .

[0054] At least two rods 14 are provided on each mounting surface 121 of the bearing seat body 1, and the elastic protective layer 31 is sleeved on the rod 14 of the corresponding mounting surface 121 and pressed against the corresponding mounting surface 121. The rod 14 can provide installation space for the protective component 3, which is convenient for disassembly, assembly and replacement.

[0055] In some or certain embodiments, the rod portion 14 may be welded to the top portion 12 of the bearing seat body 1, and each mounting surface 121 of the top portion 12 may be provided with two rod portions 14 spaced apart along the length L of the bearing seat body 1. This facilitates installation, reduces the precision requirements for the protective assembly 3 to be assembled, and effectively positions the elastic protective layer 31, thereby improving the reliability of the elastic protective layer 31.

[0056] In some or some embodiments, the rod 14 is provided with threads, the pressing member 32 is a pressing plate, and the protective assembly 3 further includes:

[0057] At least two nuts 33 are threadedly connected to the at least two rods 14 in a one-to-one correspondence to tighten the pressing plate.

[0058] Adding a pressure plate can compress the elastic protective layer 31, and cooperating with the nut 33 threadedly connected to the rod 14, rotating the nut 33 can increase the pressure applied by the pressure plate on the elastic protective layer 31, so that the elastic protective layer 31 can expand laterally to contact more closely with the side wall of the window 1001 of the arch 100, effectively reducing the possibility of impurities such as lubricating oil entering between the first liner 2 and the arch 100, and reducing the maintenance frequency required for the first liner 2 and the arch 100. Moreover, the protective component 3 adopts the above structure. Even after long-term use, the pressure plate and the elastic protective layer 31 in the protective component 3 need to be replaced. Since the protective component 3 is arranged on the top 12 of the bearing seat body 1, the top 12 of the bearing seat body 1 has a certain operating space, and the time required to replace the protective component 3 is short, which is also conducive to reducing maintenance costs and reducing the impact of maintenance on the production line where the rolling mill is located.

[0059] In some or certain embodiments, the pressing member 32 may be provided with a through hole 321 that cooperates with the rod 14, and the same is true for the elastic protective layer 31, so that sleeve installation can be achieved.

[0060] It should be noted that when the bearing seat assembly is installed on the arch 100, the two first linings 2 of the bearing seat body 1 are in close contact with the two side walls of the window 1001 of the arch 100, so it is difficult to disassemble. If maintenance or replacement is required, it is often necessary to disassemble the roller 200 connected to the bearing seat body 1, which takes a long time to maintain. Compared with replacing the protective component 3, the maintenance cost of replacing the first lining 2 will be much higher.

[0061] Figure 3 1 shows a cross-sectional view of a protective component 3 in some embodiments or certain embodiments of the present application, Figure 4 A longitudinal cross-sectional view of a protective assembly 3 in some or certain embodiments of the present application is shown. In some or certain embodiments, the thickness H2 of the elastic protective layer 31 is greater than or equal to the thickness H3 of the pressure plate. This helps improve the protective effect of the elastic protective layer 31 and also helps extend the service life of the elastic protective layer 31.

[0062] In some or certain embodiments, the length L3 of the pressing plate is less than or equal to the length L2 of the elastic protective layer 31, and the width B3 of the pressing plate is less than the width B2 of the elastic protective layer 31. This facilitates the assembly and disassembly of the pressing plate, and when the pressing plate presses down on the elastic protective layer 31, it also facilitates squeezing and expanding the elastic protective layer 31, so that the elastic protective layer 31 contacts the side wall of the window 1001 of the archway 100 more closely, thereby improving the protective effect of the elastic protective layer 31.

[0063] In some or certain embodiments, the pressing member 32 in the protective assembly 3 may also be a magnetic plate. There is an adsorption force between the magnetic plate and the bearing seat body 1, and the magnetic plate presses the elastic protective layer 31 onto the bearing seat body 1 through the adsorption force. Alternatively, the protective assembly 3 may also include an elastic protective layer 31 and a nut 33 that is directly threaded onto the rod 14, and the elastic protective layer 31 is pressed against the mounting surface 121 by the nut 33. Alternatively, the protective assembly 3 may also include two L-shaped clips for pressing the elastic protective layer 31, one end of the clip can press the elastic protective layer 31, and the other end can be clamped to the end of the bearing seat body 1 or tightened by a fastener. In either case, the pressing member 32 can press the elastic protective layer 31.

[0064] In some or certain embodiments, the protective assembly 3 may also include at least two screws, an elastic protective layer 31, a pressure plate, and a nut 33 sequentially sleeved on the screws. The screws are threadedly connected to the bearing housing 1. The entire protective assembly 3 can be directly replaced.

[0065] Figure 5 shows a partial structural diagram of a rolling mill in some embodiments or certain embodiments of the present application, Figure 6 A top view of a local structure of a rolling mill in some embodiments or certain embodiments of the present application is shown, with reference to Figure 5 and Figure 6 , the present application also provides a rolling mill, comprising:

[0066] The memorial arch 100 is provided with two opposite windows 1001 , and the side walls of the windows 1001 are provided with second lining plates 1002 .

[0067] A plurality of bearing seat assemblies as described above are respectively located in two windows 1001 opposite to each other, and the first lining plate 2 is in contact with the second lining plate 1002 .

[0068] The roller 200 is rotatably mounted at both ends to two pairs of bearing seat assemblies.

[0069] The structure of the bearing seat assembly and its corresponding technical effects can be found in the previous section and will not be further elaborated here. When the bearing seat assembly is installed in the archway 100 of the rolling mill, the elastic protective layer 31 can provide a certain degree of protection for both the first liner 2 and the second liner 1002, effectively reducing the frequency and cost of maintenance required for the rolling mill.

[0070] It should be noted that the bearing seat assembly can be used to mount either the upper or lower roller 200 of the rolling mill, depending on the needs. Alternatively, the bearing seat assembly can be used to mount both ends of the roller 200 of the rolling mill. The rolling mill provided in this application may be a rolling mill that requires the arch 100, roller 200, and bearing seat assembly. Alternatively, the rolling mill may further include, for example, a drive device for driving the roller 200 and other components for processing the strip. This application does not impose any restrictions on this.

[0071] In some or certain embodiments, the bearing housing 1 further includes at least two rods 14 disposed on each mounting surface 121. The elastic protective layer 31 is sleeved over the at least two rods 14 and pressed against the corresponding mounting surface 121. With the mounting surface 121 as a reference plane, the maximum height H of the rods 14 relative to the mounting surface 121 is less than the maximum height H1 of the roller 200 relative to the mounting surface 121. This allows for more space on the top 12 of the bearing housing 1 for maintaining and disassembling the protective assembly 3, thereby improving maintenance efficiency.

[0072] It should be noted that, with the mounting surface 121 as the reference plane, the total thickness of the elastic protective layer 31, the pressure plate, and the nut 33 is less than or equal to the height H of the rod 14. When both ends of the elastic protective layer 31 in the longitudinal direction protrude from the bearing seat body 1, the length L2 of the elastic protective layer 31 is less than the maximum distance L1 between the bearing seat body 1 and the roller body 2001 of the roller 200.
