DETAILED DESCRIPTION

[0024] 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.

[0025] Example

[0026] like Figures 1-6As shown in the figure, an embodiment of the present invention provides a pinch roller bearing housing with improved service life, comprising a mounting plate 1, four dampers 2 fixedly connected to the top of the mounting plate 1, the output ends of the four dampers 2 fixedly connected to the same bearing housing base 3, a bearing housing 4 fixedly connected to the top of the bearing housing base 3, a water cavity 5 formed on the bearing housing 4, four heat-conducting rods 6 fixedly connected to the bottom of the bearing housing 4, a cavity formed on the bearing housing base 3, the ends of the heat-conducting rods 6 extending into the cavity and fixedly connected to heat dissipation fins 7, a serpentine tube 8 fixedly connected to the bottom of the heat dissipation fins 7, a water tank 9 fixedly connected to the top of the mounting plate 1, a delivery pump 10 fixedly connected to the top of the water tank 9, the inlet pipe of the delivery pump 10 extending into the water tank 9, the outlet pipe of the delivery pump 10 connected to and fixedly connected to a first flexible hose 11, the end of the first flexible hose 11 extending into the water cavity 5, a second flexible hose 12 fixedly connected to the right side of the bearing housing 4, the second flexible hose... The end of the second hose 12 extends into the water cavity 5. The top of the mounting plate 1 is fixedly connected to the cooler 13. The other end of the second hose 12 extends into the cooler 13. The first hose 11 is connected to and fixed with the third hose 14. The end of the third hose 14 extends into the cavity and is connected to and fixed with the end of the serpentine tube 8. The other end of the serpentine tube 8 is connected to and fixed with the fourth hose 15. The end of the fourth hose 15 extends to the outside of the bearing seat base 3 and is connected to and fixed with the cooler 13. The bearing seat 4 is provided with a boring hole 16 and a wear-resistant layer 17. The bearing seat base 3 is provided with a corrosion-resistant layer 18. The water tank 9 and the cooler 13 are connected and fixed with a connecting pipe 19. The delivery pump 10 is started. The delivery pump 10 delivers cold water from the water tank 9 to the water cavity 5 through the first hose 11. In this way, the cold water can directly dissipate heat from the bearing seat 4 and effectively reduce its temperature. After the cold water absorbs the heat from the bearing seat 4, its temperature will rise. At this point, the hot water is transported to the cooler 13 through the second hose 12 for cooling, turning it back into cold water. Another portion of the heat generated by the bearing housing 4 is transferred to the heat dissipation fins 7 through the heat-conducting rod 6. The first hose 11 is transported to the serpentine tube 8 through the third hose 14. A portion of the cold water in the first hose 11 is also transported to the serpentine tube 8 through the third hose 14, further reducing the temperature of the heat dissipation fins 7 through heat exchange. The cooled hot water is then transported back to the cooler 13 through the fourth hose 15 for cooling. The cooled water, after being processed by the cooler 13, is then transported back to the water tank 9 through the connecting pipe 19, thus forming a complete cold water circulation system. This not only saves water resources but also ensures the continuity of heat dissipation. The wear-resistant layer 17 can effectively disperse stress, reduce local wear, and extend the service life of the bearing housing 4, while the corrosion-resistant layer 18 can form a dense protective barrier, effectively resisting the erosion of corrosive media and protecting the bearing housing base 3 from corrosion damage. This achieves efficient heat dissipation, resource conservation, and extended service life.

[0027] In some embodiments, four buffer springs 20 are fixedly connected between the top of the mounting plate 1 and the bottom of the bearing seat base 3. The buffer springs 20 are movably sleeved on the corresponding dampers 2, and the buffer springs 20 serve to buffer the load.

[0028] In some embodiments, the mounting plate 1 has four fixing holes 21, which serve as mounting holes.

[0029] In some embodiments, the corrosion-resistant layer 18 is made of a nickel-based alloy material, and the wear-resistant layer 17 is made of a high-hardness alloy steel material.

[0030] In some embodiments, four circular holes are provided on the top inner wall of the cavity. The inner walls of the circular holes do not contact the outer sides of the corresponding heat-conducting rods 6. The heat-conducting rods 6 are provided to conduct heat.

[0031] In some embodiments, a water injection pipe is connected to and fixed to the top of the water tank 9, and a cap is threaded onto the water injection pipe, which serves to block the flow.

[0032] Working principle or structural principle: When in use, the mounting plate 1 is fixed to the place of use through the fixing hole 21, cold water is added to the water tank 9 through the water injection pipe, and the delivery pump 10 is started. The delivery pump 10 delivers cold water from the water tank 9 to the water chamber 5 through the first hose 11. In this way, the cold water can directly dissipate heat to the bearing seat 4, effectively reducing its temperature. After the cold water absorbs the heat of the bearing seat 4, its temperature will rise. At this point, the hot water is transported to the cooler 13 through the second hose 12 for cooling, turning it back into cold water. Another portion of the heat generated by the bearing housing 4 is transferred to the heat dissipation fins 7 via the heat-conducting rod 6. The first hose 11 is then transported to the serpentine tube 8 through the third hose 14. A portion of the cold water in the first hose 11 is also transported to the serpentine tube 8 through the third hose 14, further reducing the temperature of the heat dissipation fins 7 through heat exchange. The cooled hot water is then transported back to the cooler 13 through the fourth hose 15 for further cooling. The cooled water, after being processed by the cooler 13, is then returned to the water tank 9 through the connecting pipe 19, thus forming a complete cold water circulation system. This system not only saves water resources but also ensures continuous heat dissipation. The wear-resistant layer 17 effectively disperses stress, reduces local wear, and extends the service life of the bearing housing 4. The corrosion-resistant layer 18 forms a dense protective barrier, effectively resisting the erosion of corrosive media and protecting the bearing housing base 3 from corrosion damage. This achieves efficient heat dissipation, resource conservation, and extended service life. When the bearing housing 4 vibrates, it compresses or stretches the buffer spring 20 through the bearing housing base 3. The buffer spring 20 acts as a buffer due to its own elasticity. The damper 2 prevents the buffer spring 20 from repeatedly rebounding, thus further buffering it.

[0033] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
