[0002] Bearings are an important component in modern mechanical equipment. Their main function is to support mechanical rotating bodies, reduce the friction coefficient during their movement, and ensure their rotation accuracy.
[0003] At present, when some heavy-duty bearings are in use, each component will generate a certain friction, and the bearing surface will dissipate a certain amount of heat. There are many existing ways to dissipate heat for the bearings, and water jacket heat dissipation is one of the many forms of heat dissipation. After the water in the water jacket absorbs heat, it will be discharged into the heat exchanger for heat exchange, and then the water after cooling will be discharged back into the water jacket for continued use. Due to the high price of the heat exchanger, it is not suitable for use by small and medium-sized enterprises. In addition, when the heat exchanger fails, it is not suitable for maintenance, which affects the normal heat dissipation of the bearing. Based on this, a bearing box water jacket cooling structure is proposed. Utility Model Content

[0022] like Figures 1 to 4 As shown, the bearing box water jacket cooling structure of this embodiment includes a base plate 1, a main shaft bearing 2, a main power shaft 3, a load roller 4 and a support plate 5. Two support plates 5 are installed on the upper end of the base plate 1, and the main shaft bearing 2 is installed between the two support plates 5. The main power shaft 3 is installed inside the main shaft bearing 2, and one end of the main power shaft 3 passes through the support plate 5. The load roller 4 is installed on the surface of the main power shaft 3. A heat dissipation box 6 is installed between the two support plates 5, and a mounting box 7 is installed inside the heat dissipation box 6. The main shaft bearing 2 is installed inside the mounting box 7 through the mounting plate. Several heat conducting plates 8 are installed on the front and rear end surfaces of the heat dissipation box 6. One end of the heat conducting plate 8 extends to the inside of the mounting box 7. The heat conducting plate 8 has a good heat transfer effect, which is convenient for conducting the heat inside the heat dissipation box 6 through the heat conducting plate 8. Water is placed inside the heat dissipation box 6, and the water is used to absorb the heat on the surface of the heat conducting plate 8. A circulating heat dissipation component is installed on one side of the heat dissipation box 6.
[0023] The circulating heat dissipation component includes a box body 901, a heat pipe 902, a circulation pump 903 and a heat dissipation fan 904. The box body 901 is installed at one end of the heat dissipation box 6, and a circulation pump 903 is installed at the bottom of the box body 901. The input end of the circulation pump 903 is connected to the inside of the heat dissipation box 6 through a pipe, and the output end of the circulation pump 903 is located inside the box body 901 and is equipped with a heat dissipation pipe 902. One end of the heat dissipation pipe 902 is connected to the inside of the heat dissipation box 6. A plurality of heat dissipation fans 904 are installed inside the box body 901 on one side of the heat dissipation pipe 902. The water inside the heat dissipation box 6 is pumped out by using the circulation pump 903, and the pumped water flows back to the heat dissipation box 6 for recycling through the heat dissipation pipe 902. The heat in the water will accumulate on the surface of the heat dissipation pipe 902. In this process, the heat dissipation fan 904 blows wind to the heat dissipation pipe 902 to dissipate heat to the water inside the heat dissipation box 6, effectively avoiding the high temperature of the water inside the heat dissipation box 6 and losing the heat dissipation effect. The heat dissipation pipe 902 is made of heat conductive material.
[0024] Specifically, the heat dissipation pipes 902 are distributed in a plurality of S-shaped patterns inside the box body 901, which effectively increases the blowing range of the heat dissipation fan 904 on the heat dissipation pipes 902, thereby facilitating effective heat dissipation.
[0025] Furthermore, ventilation slots 10 are provided at both ends of the box body 901. The provision of the ventilation slots 10 facilitates the normal use of the heat dissipation fan 904. A cooling component is installed inside the box body 901 on the side of the heat dissipation fan 904 away from the heat dissipation pipe 902. The cooling component is used to cool the air blown out by the heat dissipation fan 904, thereby improving the heat dissipation effect of the heat dissipation pipe 902.
[0026] Furthermore, the cooling component includes a circulation pump 1101, a connecting pipe 1102, a sprinkler pipe 1103 and a water curtain 1104. The circulation pump 1101 is installed at one end of the box 901 below the ventilation slot 10. The input end of the circulation pump 1101 is connected to the box 901. The output end of the circulation pump 1101 is installed with a connecting pipe 1102. One end of the connecting pipe 1102 is located above the inside of the box 901 and a sprinkler pipe 1103 is installed. A water curtain 1104 is installed inside the box 901 below the sprinkler pipe 1103. The water curtain 1104 is located at the top of the cooling element. The hot air blower 904 is located away from the side of the heat dissipation pipe 902, and the water inside the box 901 is pumped out through the circulation pump 2 1101, and sprinkled on the water curtain 1104 through the connecting pipe 1102 and the sprinkler pipe 1103. When the heat dissipation fan 904 rotates, the evaporation of water on the surface of the water curtain 1104 is accelerated. When the water evaporates, the heat is taken away, so that the wind blown out by the heat dissipation fan 904 is cold wind, further improving the heat dissipation effect of the heat dissipation pipe 902. The water curtain 1104 is made of water-absorbing cloth or other materials, and the circulation pump 2 1101 is started at a time for a period of time.
[0027] Furthermore, a plurality of water flow holes 12 are arranged below the surface of the sprinkler pipe 1103 . The arrangement of the water flow holes 12 facilitates the water flowing out of the sprinkler pipe 1103 to evenly contact the water curtain 1104 .
[0028] Furthermore, water is placed inside the heat sink 6 and the box body 901. Water acts as a heat-absorbing medium to absorb heat, and its cost is low compared to other coolants.
[0029] The method of use of this embodiment is as follows: when the bearing rotates, the heat generated is absorbed by the heat conducting plates 8 at both ends of the installation box 7, and the heat on the heat conducting plates 8 is absorbed by the water inside the heat dissipation box 6. At the same time, the circulation pump 1 903 pumps the water inside the heat dissipation box 6 out, and the pumped water flows back to the heat dissipation box 6 for recycling through the heat dissipation pipe 902. The heat in the water will accumulate on the surface of the heat dissipation pipe 902. During this process, the heat dissipation fan 904 blows air to the heat dissipation pipe 902 to achieve heat dissipation of the water inside the heat dissipation box 6. At the same time, the circulation pump 2 1101 pumps the water inside the box body 901 out and sprinkles it on the water curtain 1104 through the connecting pipe 1102 and the sprinkler pipe 1103. When the heat dissipation fan 904 rotates, the evaporation of water on the surface of the water curtain 1104 is accelerated. When the water evaporates, the heat is taken away, so that the wind blown out by the heat dissipation fan 904 is cold wind, which further improves the heat dissipation effect of the heat dissipation pipe 902 and ensures effective heat dissipation of the water inside the heat dissipation box 6.
[0030] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
