Description

Technical Field

[0001] This utility model relates to the field of rolling mill roll bearings, specifically a rolling mill roll bearing mechanism with a dustproof structure. Background Technology

[0002] The working environment of rolling mills is usually harsh, with a large amount of dust, metal shavings, oxide scale and other impurities. If these impurities enter the bearing, they will form abrasive particles between the rolling elements and the raceway, aggravating wear, scratching the surfaces of the rolling elements and raceway, damaging the bearing's precision and smoothness, causing unstable bearing operation, and even potentially leading to bearing seizure or failure. Therefore, a rolling mill roll bearing mechanism with a dustproof structure is needed.

[0003] Existing rolling mill roll bearing mechanisms lack dust protection during operation, allowing dust to enter the bearing and cause wear, affecting its use. They also lack heat dissipation protection, leading to high temperatures that affect bearing performance. Therefore, there is an urgent need for a rolling mill roll bearing mechanism with a dustproof structure. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a rolling mill roll bearing mechanism with a dustproof structure to solve the problems of existing rolling mill roll bearing mechanisms lacking dustproof protection during use, which leads to dust entering the bearing and causing wear, affecting use, and lacking heat dissipation protection for the bearing, which leads to high temperature affecting bearing performance.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rolling mill roll bearing mechanism with a dustproof structure, comprising an outer ring, a rolling element movably connected to the inner wall of the outer ring, an inner ring movably connected to the outer wall of the rolling element, a silicone grease layer bonded to the side wall of the outer ring, heat dissipation fins bonded to the side wall of the silicone grease layer, and bolts installed on the inner wall of the heat dissipation fins.

[0006] An oil inlet is fixedly connected to the outer wall of the outer ring. A groove is provided on the outer wall of the oil inlet. A filter plate is installed on the inner wall of the oil inlet. A spring is fixedly connected to the inner wall of the filter plate. A buckle is fixedly connected to one end of the spring.

[0007] Preferably, the heat dissipation fins are arranged in a circular shape, and the heat dissipation fins are symmetrically arranged along the central axis of the outer ring.

[0008] Preferably, the inner wall of the outer ring is provided with a threaded hole, and the outer ring is threadedly connected to the heat dissipation fins by bolts.

[0009] Preferably, the inner diameter of the heat dissipation fins is equal to the inner diameter of the inner ring, and the heat dissipation fins are arranged in a circular shape.

[0010] Preferably, the buckle is movably connected to the filter plate, and the buckle is inserted into the slot.

[0011] Preferably, the buckles are arranged in a circular array around the central axis of the filter plate, and the filter plate is engaged with the oil inlet.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model, through the setting of an outer ring, a silicone grease layer, heat dissipation fins, and bolts, allows the silicone grease layer bonded to the outer ring to adhere tightly to the surfaces of the outer ring and the heat dissipation fins, filling the tiny gaps and uneven areas between them. This makes the contact between the heat dissipation fins and the outer ring tighter and more uniform. Furthermore, the heat dissipation fins significantly increase the heat dissipation area, accelerating the dissipation of heat from the outer ring to the surrounding air, effectively reducing the operating temperature of the bearing, and preventing problems such as bearing performance degradation and lubrication failure due to overheating. At the same time, it can also shield the rolling elements, effectively preventing external dust and other foreign objects from entering the bearing, avoiding these foreign objects from causing wear on the rolling elements, thereby ensuring the normal operation and service life of the rolling elements.

[0014] 2. This utility model, through its oil inlet, slot, filter plate, spring, and buckles, uses a filter plate to prevent dust particles from entering the oil inlet with the air, reducing the possibility of dust entering the bearing and thus helping to keep the bearing clean and maintain its good working performance. By pressing the buckles around the filter plate, the buckles disengage from the slot and retract into the filter plate, causing the spring to compress and then the filter plate to be removed from the oil inlet. Subsequently, the buckles are reset by the spring's rebound. The filter plate can be quickly removed for maintenance and replacement without the need for tools. Attached Figure Description

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0021] The embodiments of this utility model will be described below based on its overall structure.

[0022] Please see Figures 1-4 A rolling mill roll bearing mechanism with a dustproof structure includes an outer ring 1, a rolling element 2 movably connected to the inner wall of the outer ring 1, an inner ring 3 movably connected to the outer wall of the rolling element 2, a silicone grease layer 4 bonded to the side wall of the outer ring 1, heat dissipation fins 5 bonded to the side wall of the silicone grease layer 4, bolts 6 installed on the inner wall of the heat dissipation fins 5, the heat dissipation fins 5 being annular in shape and symmetrically arranged around the central axis of the outer ring 1, threaded holes formed on the inner wall of the outer ring 1, and the outer ring 1 being threadedly connected to the heat dissipation fins 5 by bolts 6. The inner diameter of the heat dissipation fin 5 is equal to the inner diameter of the inner ring 3, and the heat dissipation fin 5 is arranged in a circular shape. When the device is in use, the heat dissipation can be accelerated by the silicone grease layer 4 and the heat dissipation fin 5 arranged on the outer ring 1, effectively reducing the working temperature of the bearing and preventing problems such as bearing performance degradation and lubrication failure caused by overheating. At the same time, it can also shield the rolling element 2, blocking external dust and other foreign objects, reducing the wear caused by dust and other foreign objects on the rolling element 2, and improving the service life of the rolling element 2.

[0023] Please see Figures 1-4 A rolling mill roll bearing mechanism with a dustproof structure includes an oil inlet 7 fixedly connected to the outer wall of an outer ring 1. A groove 8 is formed on the outer wall of the oil inlet 7. A filter plate 9 is installed on the inner wall of the oil inlet 7. A spring 10 is fixedly connected to the inner wall of the filter plate 9. A buckle 11 is fixedly connected to one end of the spring 10. The buckle 11 is movably connected to the filter plate 9 and engages with the groove 8. The buckles 11 are arranged in a circular array around the central axis of the filter plate 9, and the filter plate 9 is engaged with the oil inlet 7. During operation, the mechanism is designed to... The filter plate 9 prevents dust particles from entering the oil inlet 7 with the air, thus helping to keep the bearing clean and maintain its good working performance. By pressing the buckle 11, the buckle 11 is disengaged from the slot 8, and then the filter plate 9 can be removed. The filter plate 9 can be quickly removed without the use of tools for maintenance and replacement. When the oil inlet 7 is not in use, a sealing plug can be installed above the oil inlet 7 to prevent the oil inlet 7 from always being in an open state, which would cause dust particles to enter the oil inlet 7 with the air.

[0024] Working Principle: In use, first move the device to a suitable position, then apply the silicone grease layer 4 to the sidewalls of both sides of the outer ring 1. Next, adhere the heat dissipation fins 5 to the silicone grease layer 4 and fix the heat dissipation fins 5 to the outer ring 1 with bolts 6. When the device is in use and generates heat, the silicone grease layer 4 transfers the heat to the heat dissipation fins 5. The heat dissipation fins 5 then increase the heat dissipation area, dissipating the heat from around the outer ring 1. Simultaneously, the heat dissipation fins 5 also shield the rolling element 2, preventing external dust particles from entering and causing wear. Furthermore, the filter plate 9 prevents dust particles from entering the oil inlet 7 and then the device itself. When wear occurs inside the device and the filter plate 9 needs to be replaced after long-term use, simply press the clips 11 around the filter plate 9 to disengage them from the slots 8 around the oil inlet 7, and then retract them into the filter plate 9. At the same time, the spring 10 will contract, and the filter plate 9 can be removed from the oil inlet 7. Then, the elasticity of the spring 10 will push the clips 11 back to their original position. When the oil inlet 7 is not in use, a sealing plug can be installed above the oil inlet 7 to prevent dust particles from entering the oil inlet 7 with the air. This completes the use of the device.
