Abstract
Description
Technical Field
[0001] This application relates to the field of aluminum roller technology, and in particular to an easily detachable aluminum roller. Background Technology
[0002] Aluminum rollers, as an important industrial equipment, are mainly made of aluminum alloy. Due to their lightweight, high strength and good thermal conductivity, they are widely used in many industries, especially in printing, packaging and metal processing. Aluminum rollers are an ideal choice to meet high-standard production requirements due to their unique physical and chemical properties.
[0003] In existing methods, before the aluminum roller is put into operation, the workers install bearings at both ends of the aluminum roller. During installation, the workers heat the aluminum roller, causing both ends of the aluminum roller to expand due to heat. At this time, the opening diameter of both ends of the aluminum roller increases after expansion. The workers then install the bearings at both ends of the aluminum roller. After the aluminum roller cools and shrinks, the outer ring of the bearing has an interference fit with the aluminum roller, and the inner ring of the bearing is used to install the rotating rod.
[0004] The aforementioned installation parts are subjected to significant forces during prolonged operation, causing deformation of the aluminum roller and affecting its stability during high-speed rotation. This situation warrants improvement. Utility Model Content
[0005] In order to prevent the aluminum roller from directly contacting the bearing, thereby reducing the possibility of aluminum roller deformation and improving the stability of the roller body when rotating at high speed, this application provides an aluminum roller that is easy to disassemble.
[0006] This application provides an easily detachable aluminum roller, employing the following technical solution:
[0007] An easily detachable aluminum roller includes a roller body and steel sleeves installed at both ends of the roller body. The steel sleeves are interference-fitted with the roller body, and a through hole is provided on the steel sleeve, through which a rotating rod passes.
[0008] By adopting the above technical solution, the main body of the aluminum roller is a roller body, and steel sleeves are installed at both ends. The interference fit between the steel sleeves and the roller body ensures a tight connection between the two, preventing loosening during use, thereby improving the overall stability and service life of the aluminum roller. The through hole allows the rotating rod to pass through it, enabling flexible connection between the aluminum roller and the drive system. This allows workers to disassemble and reinstall the aluminum roller through the through hole when cleaning, inspection, or replacement is required, simplifying the maintenance process. The above design prevents the aluminum roller from directly contacting the bearing, thereby reducing the possibility of deformation and improving the stability of the roller body during high-speed rotation.
[0009] Optionally, the steel sleeve includes a steel shell that mates with the inner wall of the roller, a steel plate that is integrally fixed with the steel shell, and an annular plate that is elastically connected to the steel shell. The annular plate can abut against the outer ring of the bearing, and several annular plates are spaced apart.
[0010] By adopting the above technical solution, the elastic connection between the annular plate and the steel shell allows for a certain radial and axial displacement, thereby better adapting to the small deformation and axial movement of the bearing, reducing bearing wear and failure risk. At the same time, the arrangement of several annular plates provides a uniform distribution of support force for the bearing, reducing the possibility of local overload and extending the service life of the bearing.
[0011] Optionally, the annular plate is inclined, with the side of the annular plate closer to the steel plate being higher than the side farther from the steel plate.
[0012] By adopting the above technical solution, the inclined annular plate makes the installation and disassembly of the bearing easier. The side of the annular plate closer to the steel plate is higher than the side of the annular plate farther from the steel plate, thus enabling the annular plate to guide the bearing into the correct position and reducing the difficulty of alignment during bearing installation.
[0013] Optionally, the through hole is formed on the side wall of the steel plate, and a rotating bearing is installed on the side wall of the steel plate. The outer ring of the rotating bearing is fixed to the inner wall of the through hole, and the inner ring of the rotating bearing is fixed to the side wall of the rotating rod.
[0014] By adopting the above technical solution, a stable connection between the rotating rod and the aluminum roller is achieved by fixing the rotating bearing in the through hole of the steel plate side wall. This connection method not only improves the support strength of the rotating rod, but also reduces the risk of bearing loosening due to vibration or impact and the possibility of bearing displacement or deformation when bearing load, thereby enabling the equipment to operate stably.
[0015] Optionally, the outer side of the steel shell is provided with a plurality of inclined holes, and a baffle plate is provided in the inclined holes. The baffle plate slides and engages with the inclined holes, and the end of the baffle plate can abut against the outer side of the bearing.
[0016] By adopting the above technical solution, when the worker inserts the bearing into the steel shell, the worker slides the baffle plate away from the steel sleeve, and then inserts the bearing into the inner wall of the steel shell. At this time, the worker blocks the baffle plate to the outside of the bearing, reducing the possibility of the bearing sliding away from the steel shell.
[0017] Optionally, the inclined hole communicates with the inner wall of the steel shell, and the end of the baffle plate communicates with the inner wall of the steel shell through the inclined hole.
[0018] By adopting the above technical solution, before the workers install the bearing, the end of the baffle plate passes through the inclined hole and is located on the inner wall of the steel shell. When the workers install the bearing, the outer ring of the bearing abuts against the end of the baffle plate. At this time, under the action of the bearing, the end of the baffle plate is lifted up, and the end of the baffle plate away from the steel plate falls in the opposite direction. Then, the end of the baffle plate away from the steel plate abuts against the outer side of the bearing, which simplifies the operation of the workers.
[0019] Optionally, a support block is provided in the inclined hole, and the support plate can abut against the side wall of the blocking plate.
[0020] By adopting the above technical solution, when the bearing lifts the blocking plate, the blocking plate rotates around the support block as the fulcrum, which reduces the possibility of the blocking plate sliding on the inner wall of the inclined hole and increases the stability of the blocking plate during operation.
[0021] In summary, this application includes at least one of the following beneficial technical effects:
[0022] 1. When the workers install the steel sleeve, they heat the aluminum roller to make the roller body expand due to heat. At this time, the opening diameter at both ends of the roller body becomes larger. Then, the workers install the steel sleeve to both ends of the roller body. When the roller body cools down, the steel sleeve achieves an interference fit with the roller body. The workers then insert the bearing into the inner wall of the steel sleeve. At this time, the rotating rod passes through the inside of the through hole. This setting prevents the aluminum roller from directly contacting the bearing, thereby reducing the possibility of deformation of the aluminum roller and improving the stability of the roller body when rotating at high speed.
[0023] 2. The inclined setting and elastic connection of the annular plate provide a more uniform distribution of support force for the bearing, reducing the risk of local overload. At the same time, under the support of the annular plate, the bearing works stably on the inner wall of the steel shell.
[0024] 3. When the worker installs the bearing onto the inner wall of the steel shell, the bearing pushes up the end of the baffle plate closest to the steel plate. At this time, the baffle plate rotates around the support block as a fulcrum, and the end of the baffle plate away from the steel plate abuts against the outer wall of the bearing, reducing the possibility of the bearing slipping out of the steel shell.

[0030] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.
[0031] This application discloses an easily detachable aluminum roller.
[0032] Example 1
[0033] Reference Figure 1 An easily detachable aluminum roller includes a roller body 1 and steel sleeves 2 installed at both ends of the roller body 1. The roller body 1 has a central shaft groove inside, with the openings of the central shaft groove located at both ends of the roller body 1. The steel sleeves 2 are installed at the openings of the central shaft groove. The inner wall of the steel sleeves 2 is annular, and its diameter is the same as that of the bearing. The side wall of the steel sleeves 2 has a through hole 3, which is coaxial with the roller body 1, and the diameter of the through hole 3 is larger than the radius of the rotating rod.
[0034] When the workers use the aluminum roller, they heat the roller to expand the roller body 1. At this time, the diameter of the openings at both ends of the roller body 1 increases. The workers then install the steel sleeve 2 into both ends of the roller body 1. When the roller body 1 cools down, the steel sleeve 2 and the roller body 1 achieve an interference fit. Then, the workers clamp the bearing onto the inner wall of the steel sleeve 2 and make the bearing and the steel sleeve 2 interference fit by tapping. At this time, the rotating rod is located in the inner ring of the bearing, the steel sleeve 2 is fixed to the outer ring of the bearing, the rotating rod passes through the through hole 3, and the rotating rod is away from the steel sleeve 2, thus realizing the installation of the bearing.
[0035] According to Embodiment 1 of this application, the implementation principle of an easily detachable aluminum roller is as follows: Before the worker uses the aluminum roller, the worker attaches the steel sleeve 2 to both ends of the roller body 1. At this time, the steel sleeve 2 and the roller body 1 are interference-fitted. Then, the worker attaches the bearing to the inner wall of the steel sleeve 2. At this time, the outer ring of the bearing is interference-fitted with the steel sleeve 2. The inner ring of the bearing is fixed with a rotating rod, which passes through the through hole 3. This arrangement prevents the aluminum roller from directly contacting the bearing, thereby reducing the possibility of deformation of the aluminum roller and improving the stability of the roller body 1 when rotating at high speed.
[0036] Example 2
[0037] Example 2 differs from Example 1 in that: (Refer to...) Figure 2The steel sleeve 2 includes a steel shell 21, a steel plate 22 integrally fixed to the steel shell 21, and several annular plates 23 elastically connected to the inner wall of the steel shell 21. The shape of the annular plates 23 fits the shape of the inner wall of the steel shell 21, and four annular plates 23 are evenly spaced. The annular plates 23 are elastically connected to the inner wall of the steel shell 21 by springs. Six springs are provided on the side wall of each annular plate 23. The six springs are distributed in two rows from the axial direction of the steel shell 21. The springs closer to the steel plate 22 are longer than the springs farther away from the steel plate 22. This arrangement makes the annular plates 23 inclined on the inner wall of the steel shell 21. A rotating bearing 4 is provided on the steel plate 22. The outer ring of the rotating bearing 4 is fixed to the inner wall of the through hole 3. The inner ring of the rotating bearing 4 can be interference-fitted with the rotating rod. The arrangement of the rotating bearing 4 further increases the stability of the aluminum roller when rotating.
[0038] According to Embodiment 2 of this application, the implementation principle of an easily detachable aluminum roller is as follows: When the worker installs the bearing, the worker manipulates the bearing to approach the steel shell 21. At this time, under the guidance of the inclined annular plate 23, the worker clamps the bearing onto the inner wall of the steel shell 21. The setting of the annular plate makes the steel shell 21 more adaptable to the small radial or axial movement of the bearing. At the same time, the rotating rod is interference-fitted with the rotating bearing 4. This setting further increases the stability of the bearing when it works on the aluminum roller.
[0039] Example 3
[0040] Example 3 differs from Example 2 in that: (Refer to...) Figure 3 and Figure 4 The steel shell 21 has several inclined holes 5. In this embodiment, four inclined holes 5 are preferably provided. The four inclined holes 5 are evenly spaced on the outer wall of the steel shell 21. The opening of the inclined holes 5 is square and communicates with the inner wall of the steel shell 21. A baffle plate 6 is provided inside the inclined hole 5. The baffle plate 6 is preferably L-shaped. The end of the baffle plate 6 away from the steel plate 22 is the right-angle end of the baffle plate 6, which can abut against the outer wall of the bearing. The end of the baffle plate 6 near the steel plate 22 passes through the inclined hole 5 and is located on the inner wall of the steel shell 21. A support block 7 is also provided inside the inclined hole 5. The support block 7 is located near the inner wall of the steel shell 21 and is integrally fixed with the steel shell 21. The side wall of the baffle plate 6 can abut against the support block 7.
[0041] According to Embodiment 3 of this application, the implementation principle of an easily detachable aluminum roller is as follows: When the worker installs the bearing, the worker manipulates the bearing to approach the steel shell 21, and the outer ring of the bearing abuts against the inner wall of the steel shell 21. At this time, the outer ring of the bearing also abuts against the end of the baffle plate 6 near the steel plate 22. Subsequently, under the action of the bearing, the end of the baffle plate 6 near the steel plate 22 is pushed away from the bearing. Under the action of the support block 7, the end of the baffle plate 6 away from the steel plate 22 moves in the opposite direction to the end of the baffle plate 6 near the steel plate 22. Subsequently, the side wall of the baffle plate 6 abuts against the side wall of the bearing. Under the blocking action of the baffle plate 6, the possibility of the bearing sliding in the axial direction is reduced. When the worker removes the bearing, the bearing can be pulled out of the steel shell 21 by applying a large force in the axial direction. This setting makes the axial fixation of the bearing more reliable.
[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
