Description

Technical Field

[0001] This utility model relates to the field of guide wheel technology, specifically a labyrinth-type guide wheel. Background Technology

[0002] In the production of hot-rolled profiles, the rolling temperature is generally above 980 degrees Celsius. Each production pass requires a guide plate to guide the feed pass for rolling. To solve the wear and damage between the product surface and the guide plate, rolling guide wheels are added for improvement. There is a 5 mm gap between the guide wheel shim and the guide assembly, and the bearing rolling elements are exposed on the outside. Existing guide wheel bearings are prone to grease loss in high-temperature and water-flushing environments. Under high-temperature, impact load, and insufficient grease lubrication conditions, guide wheel bearings are easily damaged, significantly reducing their service life and seriously affecting the surface quality of the product. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of the aforementioned background technology by proposing a labyrinth-type guide wheel.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a labyrinth-type guide wheel, including a guide plate, two sets of wheel grooves on one side of the guide plate, a guide wheel body inside the wheel grooves, mounting seats at both ends of the guide wheel body, a fixed shaft rotatably connected to the middle of the guide wheel body and fixedly connected to the inner wall of the wheel groove, a bearing body installed on the inner wall of the mounting seat, and the bearing body sleeved on the surface of the fixed shaft, a cover plate threaded to both ends of the fixed shaft, a labyrinth mechanism for preventing moisture from entering at both ends of the guide wheel body, and a self-lubricating centrifugal mechanism inside the guide wheel body.

[0005] Preferably, the inner diameter of the mounting base is adapted to the outer diameter of the bearing body, and the inner diameter of the bearing body is adapted to the outer diameter of the fixed shaft, thereby improving the stability of the assembly.

[0006] Preferably, the maze mechanism includes a first gasket and a second gasket. The first gasket is provided at one end of the guide wheel body, and the second gasket is provided at the other end. Both ends of the guide wheel body are rotatably connected to the first and second gaskets, respectively. A rotating groove, rotatably connected to the guide wheel body, is provided on one side of the first gasket. Two sets of maze grooves are provided at both ends of the guide wheel body, with the inner wall of one end of each maze groove being inclined. Maze plates are slidably connected inside each maze groove, and the maze plates are fixedly connected to the inner wall of the rotating groove and one side of the second gasket, respectively. Inclined flow channels are evenly provided on the inner wall of one side of each maze groove, with one end of each flow channel pointing towards the inside of the mounting base and the outside of the guide wheel body, respectively, to prevent the loss of internal lubricating oil and to prevent external moisture from entering the device and causing corrosion.

[0007] Preferably, the two sets of labyrinth grooves on the same side of the guide wheel body are of different sizes, which facilitates the formation of a labyrinth-like barrier.

[0008] Preferably, the inner wall of the labyrinth groove on one side of the guide wheel body is inclined to facilitate the flow of lubricating oil and water.

[0009] Preferably, the centrifugal mechanism includes a centrifugal oil storage tank, the centrifugal oil storage tank is provided inside the guide wheel body, an oil injection channel connected to the centrifugal oil storage tank is provided at one end of the guide wheel body, a one-way oil injection nozzle is installed at one end of the oil injection channel, and a lubricating oil channel is provided on the inner wall at the bottom of the centrifugal oil storage tank to facilitate self-lubrication of the device.

[0010] Preferably, one end of the centrifugal oil storage tank and the lubrication oil passage are respectively connected to two sets of mounting seats to facilitate self-lubrication of the bearing body.

[0011] Preferably, the outer wall of the centrifugal oil storage tank is inclined, and the two ends of the centrifugal oil storage tank are inclined in opposite directions, so as to provide power for the lubricating oil through centrifugal force and inclined surface.

[0012] Compared with the prior art, the beneficial effects of this utility model are: During movement, the product drives the guide wheel to rotate. This rapid rotation of the guide wheel causes the lubricating oil inside the centrifugal oil storage tank to rotate as well. Under the influence of centrifugal force and the inclined surface at the top of the storage tank, the lubricating oil flows upwards, lubricating the bearings. Excess lubricating oil is blocked by the inner labyrinth grooves and plates, flowing through the channels to the mounting base and finally back into the centrifugal oil storage tank, achieving internal circulation and self-lubrication. Simultaneously, the outer labyrinth grooves and plates prevent external moisture from entering the guide wheel, avoiding corrosion of the bearings. Condensed water is discharged through the channels, further protecting the device. The lubricating oil at the bottom of the centrifugal oil storage tank, under the influence of the lower inclined surface and gravity, flows through the lubricating oil channels to a set of bearings at the bottom of the guide wheel. The top of the main body lubricates the lower set of bearing bodies. The labyrinth groove and labyrinth plate further prevent oil loss, reducing oil consumption. Users can easily replenish lubricating oil into the centrifugal oil reservoir via the oil inlet channel and one-way nozzle. When the lubricating oil evaporates at high temperature, the resulting lubricating vapor also enters the bearing body, improving lubrication and further reducing wear, significantly increasing the bearing's lifespan. The labyrinth-type first and second gaskets not only reduce oil loss but also prevent external moisture from entering the inner wall of the device, thus preventing bearing corrosion. They also achieve self-lubrication during rotation, ensuring the bearing body is lubricated during operation, further extending its lifespan and guaranteeing product surface quality.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1-6 One embodiment provided by this utility model: A labyrinth-type guide wheel includes a guide plate 1. Two sets of wheel grooves 2 are provided on one side of the guide plate 1. A guide wheel body 3 is provided inside the wheel groove 2. Mounting seats 4 are provided at both ends of the guide wheel body 3. A fixed shaft 6 is rotatably connected to the middle of the guide wheel body 3 and fixedly connected to the inner wall of the wheel groove 2. A bearing body 5 is installed on the inner wall of the mounting seat 4 and the bearing body 5 is sleeved on the surface of the fixed shaft 6. A cover plate 7 is threaded to both ends of the fixed shaft 6. A labyrinth mechanism for preventing water vapor from entering is provided at both ends of the guide wheel body 3. A self-lubricating centrifugal mechanism is provided inside the guide wheel body 3. Furthermore, the maze mechanism includes a first gasket 8 and a second gasket 9. The first gasket 8 is provided at one end of the guide wheel body 3, and the second gasket 9 is provided at the other end. Both ends of the guide wheel body 3 are rotatably connected to the first gasket 8 and the second gasket 9, respectively. A rotating groove 10, rotatably connected to the guide wheel body 3, is provided on one side of the first gasket 8. Two sets of maze grooves 11 are provided at both ends of the guide wheel body 3, and the inner wall of one end of each maze groove 11 is inclined. Maze plates 13 are slidably connected inside each maze groove 11, and the maze plates 13 are fixedly connected to the inner wall of the rotating groove 10 and one side of the second gasket 9, respectively. Inclined flow channels 12 are evenly provided on the inner wall of one side of each maze groove 11, and one end of each flow channel 12 points to… The labyrinth groove 11 and labyrinth plate 13 on the outside of the mounting base 4 and the outer side of the guide wheel body 3 can prevent external water vapor from entering the interior of the guide wheel body 3, thus avoiding corrosion of the bearing body 5. At the same time, the water vapor condenses and is discharged to the outside through the flow channel 12, further protecting the device. The lubricating oil in the lower part of the centrifugal oil storage tank 14 flows to the top of a set of bearing bodies 5 at the bottom of the guide wheel body 3 through the lubricating oil channel 17 under the action of its lower inclined surface and gravity, thereby lubricating the lower set of bearing bodies 5. At the same time, the labyrinth groove 11 and labyrinth plate 13 can again prevent the loss of lubricating oil, reduce the loss of lubricating oil, prevent the loss of internal lubricating oil, and prevent external water vapor from entering the device and causing corrosion. Furthermore, the centrifugal mechanism includes a centrifugal oil storage tank 14. The centrifugal oil storage tank 14 is located inside the guide wheel body 3. One end of the guide wheel body 3 has an oil inlet channel 15 connected to the centrifugal oil storage tank 14. A one-way oil inlet nozzle 16 is installed at one end of the oil inlet channel 15. A lubricating oil channel 17 is located on the inner wall at the bottom of the centrifugal oil storage tank 14. The rapidly rotating guide wheel body 3 drives the lubricating oil inside the centrifugal oil storage tank 14 to rotate. At this time, under the action of centrifugal force and the inclined surface at the top of the centrifugal oil storage tank 14, the lubricating oil can flow upwards, thereby stimulating the bearing body. 5. Lubrication is performed. Excess lubricating oil is blocked by the inner labyrinth groove 11 and labyrinth plate 13, flows through the flow channel 12 to the inside of the mounting base 4, and finally flows to the inside of the centrifugal oil storage tank 14, thereby realizing the self-lubricating effect of internal circulation, which facilitates the self-lubrication of this device. One end of the centrifugal oil storage tank 14 and the lubricating oil channel 17 are respectively connected to the two sets of mounting bases 4, which facilitates the self-lubrication of the bearing body 5. The outer wall of the centrifugal oil storage tank 14 is inclined, and the inclination directions of the two ends of the centrifugal oil storage tank 14 are opposite, which provides power for the lubricating oil through centrifugal force and inclined surface. It should be noted that the inner diameter of the mounting base 4 is adapted to the outer diameter of the bearing body 5, and the inner diameter of the bearing body 5 is adapted to the outer diameter of the fixed shaft 6, which improves the stability of the assembly. The two sets of labyrinth grooves 11 on the same side of the guide wheel body 3 have different sizes, which facilitates the formation of a labyrinth-type barrier. The inner wall of the labyrinth groove 11 on one side of the guide wheel body 3 is inclined, which facilitates the flow of lubricating oil and water.

[0017] During the movement of the product, the guide wheel body 3 rotates. The rapidly rotating guide wheel body 3 causes the lubricating oil inside the centrifugal oil storage tank 14 to rotate as well. Under the influence of centrifugal force and the inclined surface of the centrifugal oil storage tank 14, the lubricating oil flows upwards, thus lubricating the bearing body 5. Excess lubricating oil is blocked by the inner labyrinth groove 11 and labyrinth plate 13, flows through the flow channel 12 to the interior of the mounting base 4, and finally flows into the centrifugal oil storage tank 14, achieving internal circulation and self-lubrication. Simultaneously, the outer labyrinth groove 11 and labyrinth plate 13 prevent external moisture from entering the guide wheel body 3, avoiding corrosion of the bearing body 5. Condensed water is discharged to the outside through the flow channel 12, further protecting the device. The lubricating oil at the bottom of the centrifugal oil storage tank 14, under the influence of its lower inclined surface and gravity, flows through the lubricating oil channel 17 to the bottom of the guide wheel body 3. The top of a set of bearing bodies 5 lubricates the lower set of bearing bodies 5. Simultaneously, the labyrinth groove 11 and labyrinth plate 13 prevent lubricant loss, reducing oil consumption. Users can easily replenish lubricant into the centrifugal oil reservoir 14 via the oil inlet 15 and one-way oil nozzle 16. When the lubricant evaporates at high temperature, the resulting lubricant vapor also enters the bearing body 5, improving lubrication and further reducing wear, significantly increasing its service life. The labyrinth-type first gasket 8 and second gasket 9 not only reduce lubricant loss but also prevent external moisture from entering the inner wall of the device, thus preventing corrosion of the bearing body 5. They also achieve self-lubrication during rotation, ensuring the bearing body 5 is lubricated during operation, further extending its service life and guaranteeing product surface quality.
