Description

Technical Field

[0001] This application relates to the technical field of centrifugal equipment, and particularly to a running wheel structure and a centrifugal equipment. Background Art

[0002] Centrifuges are mainly applied to the tube mold centrifugation process in the production of concrete prestressed pipe piles. The tube mold centrifugation process is a process in which molten iron is evenly distributed on the inner wall of the tube mold by the action of centrifugal force to form a tubular product. The running wheel structure of traditional centrifuges has the disadvantages of large vibration, poor reliability, and high noise. The severe vibration of the centrifuge causes loosening of links such as the foundation anchor bolts of the base, the set bolts of the running wheel taper sleeve, and the set bolts of the bearing seat. At the same time, it will reduce the service life of the bearings, cause equipment damage, or phenomena such as flying molds. Utility Model Content

[0008] In the running wheel structure of the present application, the support ring is used to contact the surface of the centrifuged part, and the high-speed rotation of the support ring drives the centrifuged part to perform the centrifugation process. The running wheel is used to connect with the output shaft of the driving device in the centrifugal equipment so that the running wheel can rotate around its axial direction. Since the retaining ring is fixedly connected to the running wheel, the retaining ring can be driven to rotate by the running wheel. Also, since the elastic damping ring is tightly connected to the retaining ring and the support ring, when the retaining ring rotates, the retaining ring can drive the support ring to rotate to achieve the centrifugation effect on the centrifuged part. During this process, intense vibration will occur on the support ring that is in direct contact with the centrifuged part. Since there is a first damping space between the retaining ring and the support ring, and the elastic damping ring is at least partially arranged in the first damping space along its axial direction, in this way, the elastic damping ring can directly contact the support ring along the radial direction of the running wheel to directly provide a damping function for the support ring through the elastic damping ring, so that the support ring has a good damping effect.

[0042] Referring to Figure 1 and Figure 2 As shown, the structure of the running wheel 100 involved in the embodiment of this application is applied to a centrifugal device. The structure of the running wheel 100 includes: a running wheel 100, a retaining ring 200, a support ring 300, and an elastic damping ring 500.

[0043] Specifically, the retaining ring 200 is sleeved on at least a part of the running wheel 100 along the axial direction of the running wheel 100 and is fixedly connected to the running wheel 100; at least a part of the support ring 300 is sleeved on the retaining ring 200 along its axial direction, and a first damping space 400 is provided between the retaining ring 200 and the support ring 300; the elastic damping ring 500 is disposed at least partially in the first damping space 400 along its axial direction and is tightly connected to the retaining ring 200 and the support ring 300.

[0044] In the structure of the running wheel 100 of this application, the support ring 300 is used to contact the surface of the piece to be centrifuged, and the high-speed rotation of the support ring 300 drives the piece to be centrifuged to perform a centrifugation process. The running wheel 100 is used to connect to the output shaft of the driving device in the centrifugal device so that the running wheel 100 can rotate around its axial direction. Since the retaining ring 200 is fixedly connected to the running wheel 100, the retaining ring 200 can be driven to rotate by the running wheel 100. Also, since the elastic damping ring 500 is tightly connected to the retaining ring 200 and the support ring 300, when the retaining ring 200 rotates, the retaining ring 200 can drive the support ring 300 to rotate to achieve the centrifugation effect on the piece to be centrifuged. In this process, intense vibrations will occur on the support ring 300 that is in direct contact with the piece to be centrifuged. Since a first damping space 400 is provided between the retaining ring 200 and the support ring 300, and the elastic damping ring 500 is disposed at least partially in the first damping space 400 along its axial direction, in this way, the elastic damping ring 500 can be in direct contact with the support ring 300 along the radial direction of the running wheel 100 to directly provide a damping function for the support ring 300 through the elastic damping ring 500, so that the support ring 300 has a good damping effect. In this way, when performing the centrifugation process, the above-mentioned structure of the running wheel 100 can have the advantages of good damping effect and low noise.

[0045] Specifically, in this embodiment, the elastic damping ring 500 is a rubber damping ring. In addition, in other embodiments, the elastic damping ring 500 can also be made of other materials with elastic damping functions, such as elastic polyurethane, foam, latex, or silica gel, etc.

[0046] Referring to Figure 1 and Figure 3 As shown, the retaining ring 200 is sleeved on a part of the running wheel 100 along the axial direction of the running wheel 100. A part of the support ring 300 of the running wheel 100 along its axial direction is sleeved on the retaining ring 200, and another part of the support ring 300 along its axial direction is sleeved on the running wheel 100. A second damping space 600 is provided between the retaining ring 200 and the running wheel 100. The second damping space 600 is communicated with the first damping space 400. A part of the elastic damping ring 500 along its axial direction is arranged in the first damping space 400, and another part of the elastic damping ring 500 along its axial direction is arranged in the second damping space 600 and is tightly connected to the retaining ring 200 and the running wheel 100.

[0047] In this embodiment, since a part of the elastic damping ring 500 along its axial direction is arranged in the first damping space 400, and another part of the elastic damping ring 500 along its axial direction is arranged in the second damping space 600 and is tightly connected to the retaining ring 200 and the running wheel 100, therefore, the retaining ring 200 and the running wheel 100 can simultaneously play a role in tightening the elastic damping ring 500, so that the elastic damping ring 500 can be fixed between the retaining ring 200 and the support ring 300, and at the same time, the elastic damping ring 500 can be fixed between the running wheel 100 and the support ring 300, so as to improve the axial fixation of the elastic damping ring 500 and improve the structural stability of the elastic damping ring 500.

[0048] Referring to Figure 3 As shown, the running wheel 100 includes a first support portion 110 and a connecting portion 120. The connecting portion 120 protrudes axially from the first support portion 110. The retaining ring 200 is sleeved on the connecting portion 120 and is fixedly connected to the first support portion 110. The first support portion 110 protrudes radially from the connecting portion 120. A part of the support ring 300 along its axial direction away from the retaining ring 200 is sleeved on the first support portion 110. A second damping space 600 is provided between the retaining ring 200 and the first support portion 110.

[0049] In this embodiment, since the retaining ring 200 is sleeved on the connecting portion 120, the retaining ring 200 can be coaxially arranged with the running wheel 100 through the connecting portion 120. At the same time, the retaining ring 200 can be fixedly connected to the running wheel 100 through the first supporting portion 110. Since the first supporting portion 110 protrudes radially from the connecting portion 120, a part of the supporting ring 300 extending axially away from the retaining ring 200 is sleeved on the first supporting portion 110. A second damping space 600 is provided between the retaining ring 200 and the first supporting portion 110. In this way, the first supporting portion 110 can support a part of the elastic damping ring 500 extending axially away from the retaining ring 200, so that each part of the elastic damping ring 500 can directly contact the supporting ring 300, and the elastic damping ring 500 can directly provide a damping function for the supporting ring 300, thereby enabling the supporting ring 300 to have a better damping effect.

[0050] Referring to Figure 3 , Figure 4 and Figure 5 As shown, the retaining ring 200 is coaxially arranged with the running wheel 100. The retaining ring 200 has a first tightening surface 210, and the running wheel 100 has a second tightening surface 130. The first tightening surface 210 and the second tightening surface 130 are arranged at an angle, and both the first tightening surface 210 and the second tightening surface 130 are arranged at an angle with respect to the axial direction of the retaining ring 200 or the running wheel 100. The elastic damping ring 500 has a first damping portion 510 and a second damping portion 520 connected to the first damping portion 510. The first damping portion 510 and the second damping portion 520 are arranged at an angle, and the first damping portion 510 abuts against the first tightening surface 210, and the second damping portion 520 abuts against the second tightening surface 130.

[0051] Specifically, in this embodiment, referring to Figure 3 and Figure 4As shown, the retaining ring 200 includes a second support portion 220. A part of the support ring 300 that is axially away from the running wheel 100 is sleeved on the second support portion 220, and a first damping space 400 is provided between the second support portion 220 and the support ring 300. The second support portion 220 and the first support portion 110 are axially spaced along the retaining ring 200 or the running wheel 100. The diameter of the second support portion 220 gradually decreases along the axial direction of the retaining ring 200 or the running wheel 100 towards the direction close to the first support portion 110. The first tensioning surface 210 is the outer surface of the second support portion 220, so that the first tensioning surface 210 is arranged at an angle with the axial direction of the retaining ring 200 or the running wheel 100. The diameter of the first support portion 110 gradually decreases along the axial direction of the retaining ring 200 or the running wheel 100 towards the direction close to the second support portion 220. The second tensioning surface 130 is the outer surface of the first support portion 110, so that the second tensioning surface 130 is arranged at an angle with the axial direction of the retaining ring 200 or the running wheel 100. In this way, the second support portion 220 can provide a thrust for the first damping portion 510 to move towards the second damping portion 520, and the first support portion 110 can provide a thrust for the second damping portion 520 to move towards the first damping portion 510, so that both the first damping portion 510 and the second damping portion 520 have a tendency to move towards the connection between the two, thereby realizing the tensioning of the elastic damping ring 500, so that the elastic damping ring 500 can remain relatively stationary with respect to the retaining ring 200 and the running wheel 100, and improving the structural stability of the elastic damping ring 500.

[0052] In this embodiment, referring to Figure 4As shown, since the first tensioning surface 210 and the second tensioning surface 130 are arranged at an angle, and both the first tensioning surface 210 and the second tensioning surface 130 are arranged at an angle with respect to the axial direction of the retaining ring 200 or the running wheel 100, therefore, a V-shaped tensioning space 800 can be formed between the first tensioning surface 210 and the second tensioning surface 130. At the same time, since the first damping portion 510 and the second damping portion 520 are arranged at an angle, the first damping portion 510 and the second damping portion 520 can form a V-shaped elastic damping ring 500. Placing the V-shaped elastic damping ring 500 in the V-shaped tensioning space 800 can make the first damping portion 510 abut against the first tensioning surface 210, and at the same time make the second damping portion 520 abut against the second tensioning surface 130. In this way, the elastic damping ring 500 can be tensioned in the V-shaped tensioning space 800, that is, the first tensioning surface 210 provides a thrust for the first damping portion 510 to move towards the second damping portion 520, and the second tensioning surface 130 provides a thrust for the second damping portion 520 to move towards the first damping portion 510, so that both the first damping portion 510 and the second damping portion 520 have a tendency to move towards the connection between the two, thereby realizing the tensioning of the elastic damping ring 500, so that the elastic damping ring 500 can remain relatively stationary with respect to the retaining ring 200 and the running wheel 100, and the structural stability of the elastic damping ring 500 is improved.

[0053] Referring to Figure 4 As shown, the first tensioning surface 210 and the second tensioning surface 130 are spaced apart in the axial direction of the retaining ring 200 or the running wheel 100 to define a squeezing gap 700 between the first tensioning surface 210 and the second tensioning surface 130.

[0054] In this embodiment, since the first tensioning surface 210 and the second tensioning surface 130 are spaced apart in the axial direction of the retaining ring 200 or the running wheel 100, a squeezing gap 700 can be defined between the first tensioning surface 210 and the second tensioning surface 130. When the first tensioning surface 210 and the second tensioning surface 130 provide a tensioning force for the elastic damping ring 500, both the first damping portion 510 and the second damping portion 520 will produce a certain elastic deformation at the connection between the two. This elastic deformation can be accommodated in the squeezing gap 700 between the first tensioning surface 210 and the second tensioning surface 130 to prevent the first damping portion 510 from bouncing off the first tensioning surface 210 and weakening the frictional force between the first damping portion 510 and the first tensioning surface 210. Similarly, it can prevent the second damping portion 520 from bouncing off the second tensioning surface 130 and weakening the frictional force between the second damping portion 520 and the second tensioning surface 130, thereby improving the stability of the elastic damping ring 500 when it is tensioned.

[0055] Specifically, in the axial direction of the retaining ring 200 or the running wheel 100, the width of the squeezing gap 700 can be adjusted.

[0056] Specifically, in this embodiment, the first support portion 110 and the second support portion 220 are connected by bolts, and the width of the extrusion gap 700 is adjusted by screwing the bolts.

[0057] In this embodiment, the tightening force of the first tightening surface 210 and the second tightening surface 130 on the elastic shock-absorbing ring can be adjusted by adjusting the width of the extrusion gap 700, so as to adjust the tightening force of the first tightening surface 210 and the second tightening surface 130 on the elastic shock-absorbing ring in real time between multiple centrifugation processes, thereby ensuring the stability of the elastic shock-absorbing ring 500 during the centrifugation process and improving the convenience of maintaining the structure of the above-mentioned running wheel 100.

[0058] Refer to Figure 3 As shown, the support ring 300 is provided with a first groove 310, and the opening of the first groove 310 faces the retaining ring 200, so as to define a first shock-absorbing space 400 between the first groove 310 and the first tightening surface 210, and the surface of the first shock-absorbing portion 510 abuts against the first tightening surface 210 and the groove wall of the first groove 310; wherein, the groove wall of the first groove 310 facing the retaining ring 200 is arranged parallel to the first tightening surface 210.

[0059] In this embodiment, since the surface of the first shock-absorbing portion 510 abuts against the first tightening surface 210 and the groove wall of the first groove 310, thus, the first groove 310 and the first tightening surface 210 can provide a tightening force for the first shock-absorbing portion 510, so that the first shock-absorbing portion 510 can remain relatively stationary with respect to the retaining ring 200 and the support ring 300.

[0060] Continue to refer to Figure 3 As shown, the support ring 300 is provided with a second groove 320 communicating with the first groove 310, and the opening of the second groove 320 faces the running wheel 100, so as to define a second shock-absorbing space 600 between the first groove 310 and the second tightening surface 130, and the surface of the second shock-absorbing portion 520 abuts against the second tightening surface 130 and the groove wall of the second groove 320; wherein, the groove wall of the second groove 320 facing the running wheel 100 is arranged parallel to the second tightening surface 130.

[0061] In this embodiment, since the surface of the second damping portion 520 abuts against the second tensioning surface 130 and the groove wall of the second groove 320, thus, the second groove 320 and the second tensioning surface 130 can provide a tensioning force for the second damping portion 520, so that the second damping portion 520 can remain relatively stationary with respect to the retaining ring 200 and the support ring 300. At the same time, since the groove wall of the first groove 310 facing the retaining ring 200 is arranged parallel to the first tensioning surface 210, and the groove wall of the second groove 320 facing the running wheel 100 is arranged parallel to the second tensioning surface 130, thus, the first damping space 400 and the second damping space 600 can be arranged at an angle between the first groove 310, the second groove 320, the first tensioning surface 210 and the second tensioning surface 130, that is, the first damping space 400 and the second damping space 600 together form a V-shaped damping space, so that the shape of the V-shaped damping space is consistent with that of the V-shaped elastic damping ring 500. In this way, the stability of the elastic damping ring 500 in the damping space can be further improved.

[0062] Refer to Figure 5 As shown, the elastic damping ring 500 includes a plurality of arc-shaped damping portions 530, and the plurality of arc-shaped damping portions 530 are connected end to end to enclose and form the elastic damping ring 500.

[0063] Specifically, in this embodiment, there are three arc-shaped damping portions 530. In addition, the arc-shaped damping portions 530 can be four, five, six, etc.

[0064] In this embodiment, the elastic damping ring 500 can be formed by connecting a plurality of arc-shaped damping portions 530 end to end. In this way, when installing the elastic damping ring 500, each arc-shaped damping portion 530 can be individually installed on the retaining ring 200 and the running wheel 100, and then the support ring 300 can be sleeved on the elastic damping ring 500. In this way, it is convenient to disassemble and assemble the elastic damping ring 500.

[0065] Refer to Figure 3 As shown, the running wheel 100 further includes a first limiting portion 140. The first limiting portion 140 is connected to the first supporting portion 110 and is connected to one end of the first supporting portion 110 along its axial direction away from the second supporting portion 220. The first limiting portion 140 protrudes radially from the first supporting portion 110 along the first supporting portion 110. The retaining ring 200 further includes a second limiting portion 230. The second limiting portion 230 is connected to the second supporting portion 220 and is connected to one end of the second supporting portion 220 along its axial direction away from the first supporting portion 110. The second limiting portion 230 protrudes radially from the second supporting portion 220 along the second supporting portion 220. The support ring 300 is located between the first limiting portion 140 and the second limiting portion 230 to limit the axial movement of the support ring 300 through the first limiting portion 140 and the second limiting portion 230, and improve the structural stability of the support ring 300.

[0066] The centrifugal device involved in the embodiments of the present application includes the above-mentioned runner 100 structure.
