Description

Technical Field

[0001] This application relates to the field of steel rolling technology, and more particularly to an anti-slip roller device for horizontal looper guide rollers. Background Technology

[0002] Currently, the horizontal slip-on steering rollers used in hot-dip galvanizing production lines generally employ tensioning sleeve devices for bearing fixation. Because slip-on steering rollers bear significant radial and axial loads during actual operation, under prolonged high-load, continuous operation, the locking nuts on the tensioning sleeves are prone to loosening due to vibration and fatigue effects. Once the locking nuts loosen, the positioning shims originally installed between the inner ring of the tensioning sleeve and the steering roller shaft may shift or even misalign due to uneven force or changes in clearance, resulting in a phenomenon known as "displacement." This shim misalignment directly disrupts the original concentricity and support stability of the steering roller, leading to significant radial movement during operation. Repairing this fault requires maintenance personnel to sequentially disassemble the bearings, tensioning sleeve assembly, and the entire steering roller body. This process is not only cumbersome and time-consuming but also demands extremely high on-site assembly precision, significantly increasing the overall maintenance difficulty and severely impacting equipment operating efficiency and maintenance cycles. Summary of the Invention

Detailed Implementation

[0019] To better understand the technical solutions provided in the embodiments of this specification, the technical solutions of the embodiments of this specification will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the embodiments of this specification and the specific features in the embodiments are detailed descriptions of the technical solutions of the embodiments of this specification, rather than limitations on the technical solutions of this specification. In the absence of conflict, the embodiments of this specification and the technical features in the embodiments can be combined with each other.

[0020] In this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, without necessarily requiring or implying any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element. The term "two or more" includes two or more cases.

[0021] The existing hot-dip galvanized horizontal slip-on steering roller bearing uses a tensioning sleeve device. The slip-on steering roller is subjected to a large load. Under long-term high-load operation, the locking nut of the steering roller tensioning sleeve is prone to loosening. At this time, the shim located between the inner ring of the steering roller tensioning sleeve and the steering roller is prone to displacement. The steering roller is prone to radial movement. When repairing radial movement, it is necessary to disassemble the bearing, tensioning sleeve and steering roller, which makes its maintenance difficult.

[0022] In response, this application proposes an anti-slip roller device 100 for horizontal looper steering rollers.

[0023] like Figure 1 As shown, the anti-slip roller device 100 for a horizontal looper steering roller according to an embodiment of this application includes: a first half-ring 11; and a second half-ring 12, wherein the second half-ring 12 is detachably connected to the first half-ring 11. When the second half-ring 12 is connected to the first half-ring 11, the second half-ring 12 and the first half-ring 11 constitute an annular sleeve 10 sleeved on the steering roller 300; wherein the annular sleeve 10 includes an insertion portion 101 and a positioning portion 102 connected axially to the steering roller 300. like Figure 2 As shown, the insertion part 101 is inserted between the bearing tensioning sleeve 200 and the steering roller 300 and fits against the inner ring of the bearing tensioning sleeve 200, as... Figure 2 and Figure 3 As shown, the positioning part 102 is provided with a positioning member 30, which abuts against the outer peripheral wall of the steering roller 300 in the radial direction of the steering roller 300.

[0024] Understandably, the installation can be completed by splitting the first half-ring 11 and the second half-ring 12 and inserting them into the installation gap between the bearing tensioning sleeve 200 and the steering roller 300, and then splicing and fixing them together. This eliminates the need to disassemble the original bearing, tensioning sleeve and steering roller 300 as a whole, which greatly reduces the time required for maintenance operations, reduces the difficulty of on-site maintenance, and enables the repair of roller misalignment faults to be completed in a short time, reducing the impact on normal production progress.

[0025] The insertion part 101 fills the gap between the inner ring of the bearing tension sleeve 200 and the shaft of the steering roller 300 caused by the displacement of the original shim. In conjunction with the limiting surface that fits against the inner ring of the bearing tension sleeve 200, it can limit the position of the bearing tension sleeve 200 in the axial direction and prevent the bearing tension sleeve 200 from axially displacing.

[0026] The positioning component 30 is radially pressed against the outer peripheral wall of the guide roller 300, which can not only fix the anti-roller device itself to the guide roller 300, preventing the device from displacing and falling off during the operation of the guide roller 300, but also further limit the radial movement of the guide roller 300, keeping the radial runout of the guide roller 300 within the allowable range, avoiding production failures such as strip deviation and edge scraping caused by the guide roller 300 shifting, and effectively improving the stability of the horizontal looper operation.

[0027] According to the embodiments of this application, the anti-roller device 100 for a horizontal looper steering roller consists of a first half-ring 11 and a second half-ring 12 that are detachably connected to form an annular sleeve 10. During installation, the device can be snapped into the designated position without disassembling the bearing tension sleeve 200 and the steering roller 300, reducing the difficulty of maintenance and adjustment. The insertion part 101 fills the gap between the inner ring of the bearing tension sleeve 200 and the steering roller 300. The positioning part 30 achieves circumferential and axial positioning of the entire device by radially pressing against the steering roller 300, which can effectively limit the radial movement of the steering roller 300, avoid production failures caused by the displacement of the steering roller 300, and improve the stability of equipment operation.

[0028] In some embodiments, such as Figure 1 , Figures 4-6 As shown, the first semi-ring 11 includes a first plug-in semi-ring 111 and a first positioning semi-ring 112 connected together, as... Figure 7 As shown, the second half-ring 12 includes a second insertion half-ring 121 and a second positioning half-ring 122 connected together. The first insertion half-ring 111 and the second insertion half-ring 121 abut against each other in the circumferential direction of the steering roller 300 to form an insertion part 101. The first positioning half-ring 112 and the second positioning half-ring 122 are detachably connected in the circumferential direction of the steering roller 300 to form a positioning part 102.

[0029] Understandably, when the first half-ring 11 and the second half-ring 12 are assembled together, the outer diameter of the first insertion half-ring 111 and the second insertion half-ring 121 matches the inner diameter of the bearing tension sleeve 200, which can tightly fit the inner ring of the bearing tension sleeve 200 and ensure the stability of the gap filling. The first positioning half-ring 112 and the second positioning half-ring 122 form a positioning structure on the axial outer side of the insertion part 101, which facilitates the arrangement of the positioning part 30 and the connecting structure, and will not occupy additional installation space inside the bearing tension sleeve 200.

[0030] The detachable connection method of the first positioning half-ring 112 and the second positioning half-ring 122 can be snap-fit, plug-in or bolt connection, etc., which is not limited here.

[0031] In some embodiments, such as Figure 1 and Figure 2 As shown, the anti-slip roller device 100 for a horizontal looper steering roller further includes: a connecting bolt 20, a first positioning half-ring 112 having a first connecting hole 1121, a second positioning half-ring 122 having a second connecting hole 1221, the first connecting hole 1121 and the second connecting hole 1221 being arranged opposite each other in a direction tangential to the circumference of the steering roller 300, and the connecting bolt 20 being sequentially passed through the first connecting hole 1121 and the second connecting hole 1221 to be connected to the nut.

[0032] It is understandable that by locking the first positioning half-ring 112 and the second positioning half-ring 122 with the connecting bolts 20 arranged tangentially in the circumferential direction, the annular sleeve 10 can be tightened to hold the steering roller 300 as a whole, so as to avoid the connecting bolts 20 protruding from the outer circumferential surface of the annular sleeve 10 and affecting the fit between the anti-slip roller device and the surrounding structure. At the same time, the connecting structure is subjected to uniform force, the locking effect is stable, and it is convenient to quickly complete the locking operation during on-site assembly.

[0033] In some embodiments, such as Figure 6 As shown, the outer peripheral wall of the first positioning half-ring 112 is provided with a first clearance groove 1122, and the first connecting hole 1121 is provided on the side wall of the clearance groove in a direction tangent to the circumference of the first positioning half-ring 112. At least a portion of the connecting bolt 20 is located in the first clearance groove 1122.

[0034] It is understandable that the first clearance groove 1122 can accommodate the bolt cap of the connecting bolt 20, preventing the bolt cap from protruding from the outer peripheral wall of the first positioning half ring 112. This ensures that the connecting bolt 20 does not protrude from the outer periphery of the annular sleeve 10, and also eliminates the need to add extra dimensions to the anti-slip roller device in the axial direction, thus not changing the axial installation space of the original equipment.

[0035] In some embodiments, the outer peripheral wall of the second positioning half-ring 122 is provided with a second clearance groove, the second connecting hole 1221 is provided on the side wall of the second clearance groove in a direction tangent to the circumference of the second positioning half-ring 122, and the nut is located in the second clearance groove.

[0036] Understandably, the second clearance groove accommodates the nut, preventing it from protruding from the outer peripheral wall of the second positioning half-ring 122, thus ensuring the integrity of the entire anti-roller device's outer periphery and avoiding structural interference with surrounding components such as the bearing housing.

[0037] In some embodiments, such as Figure 6 and Figure 7 As shown, the first positioning half-ring 112 and / or the second positioning half-ring 122 are provided with positioning holes 1123, and the positioning member 30 passes through the positioning holes 1123.

[0038] It is understandable that the positioning hole 1123 extends radially along the steering roller 300, and the positioning part 30 can be a set screw. By tightening the set screw, the length of the positioning part 30 extending toward the steering roller 300 can be adjusted, so that the end of the positioning part 30 is stably pressed against the outer peripheral wall of the steering roller 300, thereby realizing the axial and circumferential positioning of the entire anti-roller device. The operation is simple and convenient, and the positioning reliability is high.

[0039] In some embodiments, the positioning member 30 is constructed as a set screw, and both the first half-ring 11 and the second half-ring 12 are provided with positioning holes 1123. The central angle between the set screw passing through the positioning hole 1123 of the first half-ring 11 and the set screw passing through the positioning hole 1123 of the second half-ring 12 is 180°.

[0040] Understandably, the two set screws simultaneously press against the steering roller 300 from both radial sides, resulting in uniform and symmetrical force. This ensures sufficient frictional force to prevent displacement of the anti-slip roller device relative to the steering roller 300, while also preventing unilateral force from causing the annular sleeve 10 to skew, thus further improving the overall positioning stability of the device.

[0041] In some embodiments, the positioning member 30 is configured as a tightening bolt, which is threaded into the positioning hole 1123.

[0042] Understandably, the threaded connection allows for precise adjustment of the extension length of the tightening bolt, adapting to different clearance requirements. If loosening occurs after long-term use, the tightening bolt can be tightened again to complete the adjustment without disassembling the entire device, making daily maintenance and adjustment more convenient.

[0043] In some embodiments, the positioning portion 102 protrudes radially outward from the insertion portion 101 along the annular sleeve 10 to form a step at the connection between the positioning portion 102 and the insertion portion 101.

[0044] Understandably, the step can form an axial limiting fit with the inner ring end face of the bearing tensioning sleeve 200. When the bearing tensioning sleeve 200 has an axial tendency to move, the step end face can directly abut against the inner ring end face of the bearing tensioning sleeve 200, limiting the axial displacement of the bearing tensioning sleeve 200 and further improving the limiting reliability of the entire structure. At the same time, the protruding positioning part 102 also facilitates the arrangement of the positioning part 30 and the connecting structure, and will not cause structural interference with the bearing tensioning sleeve 200.

[0045] In some embodiments, the inner diameter of the annular sleeve 10 is greater than or equal to the outer diameter of the steering roller 300, and the outer diameter of the annular sleeve 10 is less than or equal to the inner diameter of the bearing tension sleeve 200. It is understood that this dimensional fit ensures that the insertion part 101 can smoothly insert into the gap between the bearing tension sleeve 200 and the steering roller 300, while simultaneously ensuring that the outer periphery of the insertion part 101 stably conforms to the inner peripheral wall of the bearing tension sleeve 200, achieving sufficient gap filling and guaranteeing the stability of the limiting support.

[0046] In some embodiments, such as Figures 1-5 As shown, the thickness of the positioning part 102 is greater than the thickness of the insertion part 101.

[0047] Understandably, this thickness design ensures that the positioning part 102 has sufficient structural strength to install the positioning part 30 and the connecting bolt 20, meeting the structural requirements for positioning and locking, while also preventing the insertion part 101 from being unable to smoothly insert into the gap between the bearing tensioning sleeve 200 and the steering roller 300 due to excessive thickness, thus balancing the requirements of structural strength and installation compatibility.

[0048] In some embodiments, the first half-ring 11 and / or the second half-ring 12 are made of 30GrzNiZM. After quenching and tempering heat treatment, they can obtain excellent strength and toughness matching, withstand the alternating load generated during the operation of the steering roller 300, are not prone to breakage and deformation, meet the requirements of long-term high-load operation, and have a longer service life.

[0049] In some embodiments, a first chamfer is provided at the end of the insertion portion 101 away from the positioning portion 102 in the axial direction of the annular sleeve 10.

[0050] Understandably, the first chamfer can guide the insertion of the plug part 101 into the gap between the bearing tension sleeve 200 and the steering roller 300, reduce the resistance when the plug part 101 is inserted into the installation gap, facilitate quick on-site installation and alignment, improve assembly efficiency, and at the same time prevent the end edge of the plug part 101 from scratching the inner ring of the bearing tension sleeve 200 or the shaft of the steering roller 300, protecting the original mating surfaces from damage.

[0051] In some embodiments, a second chamfer is provided at the end of the positioning portion 102 away from the insertion portion 101 in the axial direction of the annular sleeve 10.

[0052] Understandably, the second chamfer can remove the sharp edges and burrs on the end face of the positioning part 102, preventing scratches to operators during assembly, and also preventing sharp edges and bumps when the positioning part 102 is installed and mated with surrounding components, thus improving structural safety.

[0053] In some embodiments, such as Figure 6 As shown, the positioning hole 1123 is disposed on the first half ring 11, and the positioning hole 1123 and the first connecting hole 1121 are distributed circumferentially on the first half ring 11.

[0054] Understandably, this spaced distribution design can prevent the positioning component 30 and the connecting bolt 20 from interfering with each other in the installation space, reduce the crowding of the structural layout, and at the same time disperse the stress points to avoid stress concentration, improve the overall structural strength and stress stability of the first half ring 11, and facilitate the tightening and adjustment of the connecting bolt 20 and the positioning component 30 during installation.

[0055] In some embodiments, the positioning hole 1123 is disposed on the second half-ring 12, and the positioning hole 1123 and the second connecting hole 1221 are spaced apart in the circumferential direction of the first half-ring 11.

[0056] Understandably, this spaced distribution design can prevent the positioning component 30 and the connecting bolt 20 from interfering with each other in the installation space, reduce the crowding of the structural layout, and at the same time disperse the stress points to avoid stress concentration, improve the overall structural strength and stress stability of the second half ring 12, and facilitate the tightening and adjustment of the connecting bolt 20 and the positioning component 30 during installation.

[0057] In some embodiments, such as Figure 2 As shown, the anti-slip roller device 100 for horizontal looper steering rollers further includes a seal 40, which is sleeved on the outside of the insertion part 101 and located between the inner ring of the bearing tensioning sleeve 200 and the positioning part 102.

[0058] Understandably, the seal 40 can block the fit gap between the plug part 101 and the inner ring of the bearing tension sleeve 200, preventing impurities such as dust, iron oxide scale and oil from entering the gap, avoiding the accumulation of impurities that cause the gap to widen, and also preventing the plug part 101 from rusting, thus extending the service life of the device and ensuring the long-term stability of the limit and anti-slip function.

[0059] In some embodiments, the seal 40 includes a first seal 41 and a second seal 42, which are detachably connected in the circumferential direction of the insertion portion 101.

[0060] Understandably, this split sealing structure can be adapted to the structure of the first half-ring 11 and the second half-ring 12. During installation, it can be synchronously inserted into the installation position along with the half-ring, without needing to be fitted from the axial end of the steering roller 300, thus meeting the installation requirements without disassembling the original equipment.

[0061] In some embodiments, one of the first seal 41 and the second seal 42 is provided with a plugging protrusion 43 and the other is provided with a plugging hole 44, and the plugging protrusion 43 is plugged into the plugging hole 44.

[0062] For example, the first seal 41 is provided with a insertion protrusion 43, and the second seal 42 is provided with a insertion hole 44; or the first seal 41 is provided with a insertion hole 44, and the second seal 42 is provided with a insertion protrusion 43; or... Figure 8As shown, the first sealing member 41 has a plugging protrusion 43 at one end in the circumferential direction and a plugging hole 44 at the other end. The second sealing member 42 has a plugging hole 44 at one end in the circumferential direction and a plugging protrusion 43 at the other end. The plugging protrusion 43 of the first sealing member 41 is plugged into the plugging hole 44 of the second sealing member 42, and the plugging hole 44 of the first sealing member 41 and the plugging protrusion 43 of the second sealing member 42 are plugged into each other.

[0063] In this way, when the first half-ring 11 and the second half-ring 12 are assembled, the insertion protrusion 43 is simultaneously inserted into the insertion hole 44 to complete the splicing of the seal 40. This ensures the overall annular integrity of the seal 40 without requiring additional connecting and fixing structures, simplifying the assembly process and ensuring the reliability of the seal. In particular, the insertion structure ensures the sealing performance of the two seals 40, preventing gaps at the joint. Furthermore, the installation and assembly operation is simple, requiring no additional connectors.
