Technical Field

[0001] This invention belongs to the technical field of casting molding, and specifically relates to a support wheel for a turning machine and the turning machine itself. Background Technology

[0002] Existing tilting machines are used to tilt boxes. During operation, the support wheel bearings frequently fail, causing downtime. The bearings in existing tilting machines are fixed within the support wheel housing. When the bearing condition needs to be checked, operators must completely disassemble the entire support wheel, a cumbersome and time-consuming process. This extreme inconvenience often leads to reduced routine maintenance, allowing the bearings to continue operating with poor lubrication or premature wear, accelerating failure, severely shortening the overall lifespan of the support wheel, and increasing maintenance costs and equipment operational risks.

[0022] Reference Figures 1 to 2 The following are several embodiments of the support wheel and the tilting machine of the present invention.

[0023] like Figures 1 to 2As shown, a support wheel for a tilting machine according to a first aspect embodiment of the present invention includes a support frame 100, a mounting shaft 200, a bearing 300, a wheel body 400, and a maintenance cover 500; the mounting shaft 200 is connected to the support frame 100; the bearing 300 is sleeved on the outside of the mounting shaft 200; the wheel body 400 is rotatably connected to the mounting shaft 200 via the bearing 300; the maintenance cover 500 is connected to the wheel body 400; the maintenance cover 500 is disposed at the end of the mounting shaft 200 away from the support frame 100, and is used to cover the mounting shaft 200 and the bearing 300.

[0024] The mounting shaft 200 is mounted on the support frame 100. The wheel 400 is sleeved on the mounting shaft 200 via the bearing 300. The wheel 400 is used to contact and form a support ring 800 on the tilting machine. When the support ring 800 rotates relative to the frame of the tilting machine, the wheel 400 rotates relative to the mounting shaft 200. Through the rotation of the wheel 400, rolling support is formed between the wheel 400 and the support ring 800, reducing frictional resistance. The inspection cover 500 is used to cover the mounting shaft 200 and the bearing 300, and the inspection cover 500 serves to prevent dust and dirt. During maintenance, the inspection cover 500 can be opened to inspect and maintain the mounting shaft 200 and the bearing 300. The inspection cover 500 is located at the end of the mounting shaft 200 away from the support frame 100, making it easy to open the inspection cover 500 and check the condition of the bearing 300 without disassembling the entire wheel 400, thus facilitating maintenance.

[0025] The support frame 100 is fixed to the tilting machine frame. The wheel 400 engages with the mounting shaft 200 via the bearing 300, converting sliding friction into rolling friction, thus reducing running resistance and wear. The mounting shaft 200 extends beyond the support frame 100, with a length of 138mm extending beyond the support frame 100. A maintenance cover 500 is located at the outer end of the wheel 400 and covers the mounting shaft 200 and bearing 300, forming a reliable seal to prevent dust and moisture from entering and extending the life of the bearing 300. Furthermore, by opening the maintenance cover 500, lubrication and inspection of the bearing 300 can be performed without disassembling the entire support wheel, thereby improving the operational reliability of the support wheel and reducing maintenance difficulty and downtime.

[0026] The mounting shaft 200 is mounted on the support frame 100. An opening can be provided on the support frame 100, and a threaded hole can be provided on the mounting shaft 200. A screw is installed in the opening, and the mounting shaft 200 is fixed to the support frame 100 by threading the screw in the opening and the threaded hole on the mounting shaft 200.

[0027] like Figure 1As shown, in some embodiments, the support wheel further includes a spacer sleeve 600, which is sleeved on the outside of the mounting shaft 200; the first end face 610 of the spacer sleeve 600 abuts against the support frame 100, and the second end face 620 of the spacer sleeve 600 abuts against the bearing 300; the spacer sleeve 600 precisely defines the axial installation position of the bearing 300, reduces the inner ring 310 of the bearing 300 from moving towards the support frame 100, and ensures the axial position stability of the wheel body 400; the spacer sleeve 600 also directly transmits the axial thrust borne by the wheel body 400 to the support frame 100 through the inner ring 310 of the bearing 300, reduces the axial load pressing on the wheel body 400, and at the same time separates the bearing 300 from the end face of the support frame 100, avoiding direct contact and friction between the two, thereby maintaining the smooth rotation of the wheel body 400 and extending the service life of the bearing 300.

[0028] The spacer sleeve 600 ensures that the inner ring 310 of the bearing 300 and the support frame 100 maintain a stable relative position, reduces the axial movement of the wheel body 400, and keeps the wheel body 400 in the correct support position. The spacer sleeve 600 reduces the axial force transmitted through the wheel body 400, thereby reducing the stress on the wheel body 400 and reducing uneven wear and indentation.

[0029] like Figure 1 As shown, in some embodiments, a shoulder 210 is provided on the side of the mounting shaft 200 away from the support frame 100; the bearing 300 has an inner ring 310 and an outer ring 320, with the outer ring 320 rotatably fitted outside the inner ring 310; the inner ring 310 is located between the spacer sleeve 600 and the shoulder 210, and the wheel body 400 is fitted outside the outer ring 320, with the wheel body 400 and the outer ring 320 fixed; the second end face 620 of the spacer sleeve 600 abuts against the inner ring 310 to restrict the inner ring 310 from sliding on the mounting shaft 200; the shoulder 210 of the mounting shaft 200 and the spacer sleeve 600 abut against the inner ring 310 of the bearing 300 from both sides, axially locking the inner ring 310 on the mounting shaft 200, preventing the inner ring 310 from sliding, thereby realizing the installation of the bearing 300. By using the spacer sleeve 600 and the shoulder of the mounting shaft 200 to limit the bearing 300, assembly and maintenance can be simplified, and the smoothness and reliability of the wheel body 400 during operation can be improved. The rotation of the wheel body 400 causes the outer ring 320 to rotate relative to the inner ring 310.

[0030] The shoulder 210 and the spacer 600 clamp and position each other, reducing the sliding of the inner ring 310 on the mounting shaft 200 and increasing the stability of the bearing 300 during operation. The shoulder 210 and the mounting shaft 200 are integrally formed, reducing the difficulty of processing and assembly. The radial and axial forces on the wheel body 400 are directly transmitted to the support frame 100 through the inner ring 310, the spacer 600 and the shoulder 210. The load transmission path is clear and direct, reducing the indentation or uneven wear of the wheel body 400 due to the additional pushing force.

[0031] like Figure 1 As shown, in some embodiments, a first embedding groove 410 is provided on the side of the wheel body 400 away from the support frame 100. The first embedding groove 410 is used to accommodate the inspection cover 500. The embedding groove plays a role in radial positioning and axial limiting of the inspection cover 500, so that the inspection cover 500 is accurately centered and flush with the end face of the wheel body 400, preventing the inspection cover 500 from protruding from the end face of the wheel body 400. The first embedding groove 410 reduces the loosening and swaying of the inspection cover 500 due to vibration during high-speed rotation. The inspection cover 500 is recessed into the end face of the wheel body 400 through the first embedding groove 410, making the wheel body 400 flat and compact, reducing the risk of spatial interference or collision caused by the outward protrusion of the inspection cover 500. The inspection cover 500 can be provided with mounting holes, and screws are provided in the mounting holes. The inspection cover 500 can be fixed to the wheel body 400 by the screws in the mounting holes.

[0032] like Figure 1 As shown, in some embodiments, the support wheel also includes a dust cover 700. The dust cover 700 is fixed to the side of the wheel body 400 near the support frame 100, and is sleeved on the outside of the mounting shaft 200. A receiving space is formed between the dust cover 700, the wheel body 400, and the inspection cover 500, which is used to accommodate the bearing 300. The dust cover 700, the wheel body 400, and the inspection cover 500 enclose the receiving space, which effectively prevents external dust, moisture, and debris from entering the bearing 300, thus improving the sealing protection of the wheel body 400. The receiving space provides a relatively closed installation environment for the bearing 300, preventing external moisture, dust, and other impurities from entering the bearing 300 and reducing the failure rate of the bearing 300. The dust cover 700 rotates synchronously with the wheel body 400, without adding additional frictional resistance, without generating wear and heat, and can provide ample grease storage space for the bearing 300, ensuring long-lasting lubrication. This reduces the risk of premature wear failure of bearing 300 due to contamination, extends the service life and maintenance cycle of bearing 300, and enables the support wheel to operate stably for a long time.

[0033] like Figure 1 As shown, in some embodiments, a second embedding groove 420 is provided on the side of the wheel body 400 near the support frame 100. The second embedding groove 420 is used to accommodate the dust cover 700. The second embedding groove 420 provides precise radial positioning and axial limiting for the dust cover 700, so that the dust cover 700 can be tightly fixed to the wheel body 400 after being embedded and rotate with the wheel body 400. The second embedding groove 420 can reduce the probability of the dust cover 700 loosening and swaying due to centrifugal force when the wheel body 400 rotates. The second embedding groove 420 makes the dust cover 700 flush with the side of the wheel body 400, reducing spatial interference caused by the outward protrusion of the dust cover 700. A fixing hole can be provided on the dust cover 700, and a screw is installed in the fixing hole. The dust cover 700 can be fixed to the wheel body 400 by the screw in the fixing hole.

[0034] like Figure 1 As shown, in some embodiments, the inner side of the inspection cover 500 is provided with a first recess 510, which is used to avoid the mounting shaft 200. Similarly, the inner side of the dust cover 700 is provided with a second recess 720.

[0035] like Figure 1 As shown, in some embodiments, the dust cover 700 is provided with a slot for the spacer sleeve 600 to pass through. A fixing groove is provided inside the slot, and a sealing ring 710 is installed within the fixing groove. The inner diameter of the sealing ring 710 is tightly fitted onto the outer circumference of the spacer sleeve 600 to seal the gap between the dust cover 700 and the spacer sleeve 600. The sealing ring 710 improves the sealing of the accommodating space, thereby reducing the risk of grease leakage from the accommodating space. It also isolates external dust, moisture, and other impurities, ensuring the bearing 300 operates stably for a long time under good lubrication. The fixing groove provides an installation position for the sealing ring 710, reducing the possibility of the sealing ring 710 detaching from the dust cover 700 and ensuring the stable installation of the sealing ring 710.

[0036] In some embodiments, bearing 300 is a double-row tapered roller bearing. The tilting machine generates significant radial loads and axial impacts on the wheel 400, and the double-row tapered roller bearing effectively supports the support ring 800 of the tilting machine. The double-row tapered roller bearing 300 allows it to simultaneously withstand radial forces and axial forces in both directions, evenly transmitting the axial force to the support frame 100, thus enhancing the load-bearing capacity of the wheel 400 and helping to maintain stable rotation of the wheel 400. In actual production operation, the support wheel bears significant radial and axial forces, and the load of the support wheel acts on the double-row tapered roller bearing. Compared to the deep groove ball bearing 300 used in existing technology, the double-row tapered roller bearing can withstand greater axial forces, thereby increasing the service life of the support wheel assembly. In actual use, statistics show that the replacement cycle of the support wheel bearing 300 has increased from 1 month to 6 months, extending its service life by 6 times.

[0037] Double-row tapered roller bearings can withstand large bidirectional axial and radial loads to support the weight of the support ring 800 of the tilting machine and the sand box on the support ring 800. In addition, double-row tapered roller bearings have a compact structure, high rigidity, and long service life, making them particularly suitable for the high-load, frequent forward and reverse rotation conditions of tilting machines.

[0038] like Figure 1 As shown, in some embodiments, there is a gap between the wheel body 400 and the support frame 100 to avoid interference between the wheel body 400 and the support frame 100, thereby ensuring the long-term flexible and stable operation of the support wheel. Specifically, the gap between the wheel body 400 and the support frame 100 is 119mm.

[0039] like Figures 1 to 2 As shown, a flipping machine provided in a second aspect embodiment of the present invention includes the support wheels of the flipping machine in any of the first aspects embodiments described above.

[0040] It is understood that since the support wheels of the tilting machine have the beneficial effects of the above embodiments, the tilting machine will have the beneficial effects of the above embodiments. The specific implementation method can be referred to the above embodiments, and this application will not repeat it.

[0041] Specifically, the flipping machine also includes a frame, a support ring 800, a drive motor, and a friction wheel 900. The support ring 800 is rotatably connected to the frame and is used to fix the sand box. The friction wheel 900 is rotatably connected to the frame, and its outer surface is in contact with the support ring 800. The drive motor is mounted on the frame and is used to drive the friction wheel 900 to rotate, thereby causing the friction wheel 900 to rotate relative to the frame, thus achieving the flipping of the sand box. During the rotation of the support ring 800, the support wheel supports the support ring 800, and the support wheel rotates under the action of the support ring 800.

[0042] The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
