Description
Technical Field
[0001] This utility model relates to the field of bearing technology, and more specifically, to a spiral circulating lubrication vertical bearing body component. Background Technology
[0002] Vertical pump bearings are the core transmission and support components of vertical pumps. Their main function is to withstand the radial and axial forces generated during pump operation, ensuring stable rotation of the pump shaft and reducing frictional losses. This directly affects the operating accuracy, efficiency, and service life of the vertical pump. They are widely used in liquid transportation scenarios in water supply and drainage, chemical, power, and metallurgical industries. When a vertical pump is running, the motor power is transmitted to the pump shaft through a coupling. The bearing, as the core support component, starts working, ensuring that the shaft maintains coaxiality during rotation and reducing radial vibration. The lubricating medium inside the bearing forms a protective film on the contact surface, reducing the coefficient of friction and wear. Combined with the sealing structure, it isolates external media and impurities, ultimately achieving stable and efficient rotation of the pump shaft and ensuring continuous liquid transportation by the vertical pump. However, traditional vertical pump bearing structures are prone to high temperature, rapid wear, and vibration failures due to lubrication and heat dissipation problems, affecting the bearing's working performance.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0018] Reference Figure 1This utility model provides a technical solution: a spiral circulating lubrication vertical bearing body component, including a bearing body 1 and a circulating lubrication mechanism. A bearing sleeve 2 is installed inside the bearing body 1, and a shaft 3 is installed inside the bearing sleeve 2. The rotational force increases the lubricating oil's power, promoting oil flow and lubricating and dissipating heat between the bearing body 1 and the bearing sleeve 2. This also allows the lubricating oil to be cooled by the lubricating oil cooling water chamber 11, preventing high temperatures, rapid wear, and vibration failures in the bearing body 1 and bearing sleeve 2 due to lubrication and heat dissipation problems during operation. Therefore, the working efficiency of the bearing body 1 and bearing sleeve 2 is improved. In a preferred embodiment, the circulating lubrication mechanism includes a spiral oil-guided bearing sleeve 4, which is located at the bottom of the bearing sleeve 2. A shaft 3 is located on the right side inside the bearing body 1. The lubricating oil inlet channel 5 and the oil guide spiral groove 6 are located at the bottom of the bearing body 1. The oil guide spiral groove 6 is connected to the lubricating oil inlet channel 5. The bottom of the bearing body 1 is provided with a lubricating oil chamber 7, which is connected to the oil guide spiral groove 6. After the oil guide spiral groove 6 rotates, it increases the power of the lubricating oil. The high-pressure power lubricating oil flows upward through the lubricating oil inlet channel 5, so that the lubricating oil in the bearing body 1 can circulate fully. As the speed increases, the circulation speed accelerates, achieving the best circulation cooling effect for the bearing. The left side of the bearing body 1 is provided with a lubricating oil return hole 8. The bottom of the lubricating oil return hole 8 is connected to the top of the lubricating oil chamber 7, which can provide working return space for the lubricating oil to circulate. This avoids the lubricating oil from having difficulty circulating during operation, thus improving the circulation effect of the lubricating oil.
[0019] Reference Figure 1 In a preferred embodiment, an oil level gauge 9 is threadedly installed at the bottom left side of the bearing housing 1. The oil level gauge 9 is connected to the lubricating oil chamber 7, facilitating timely oil replenishment, preventing insufficient lubrication and bearing overheating due to insufficient oil, ensuring stable circulating lubrication, and helping to extend bearing life. This allows the user to visually display the oil level, accurately control the oil quantity, prevent excessive or insufficient oil from affecting lubrication, maintain cooling effect, and reduce bearing wear failures. Therefore, it improves the convenience of observing and adding lubricating oil. A lower bearing cover 10 is installed at the bottom of the bearing sleeve 2. The lower bearing cover 10 is located at... On the outer side of the shaft body 3, at the bottom of the bearing body 1, there is a lubricating oil cooling water chamber 11. The lubricating oil cooling water chamber 11 is located at the bottom of the lubricating oil chamber 7. The bottom of the lower bearing cover 10 is provided with an external connection hole 12 that communicates with the lubricating oil cooling water chamber 11. This can provide a stable cold source for lubricating oil cooling, enhance the return oil cooling effect, lower the temperature of the circulating lubricating oil, further increase the cooling range of the bearing sleeve 2 and the bearing body 1, ensure the cooling effect, and avoid the situation where the lubricating oil is difficult to cool down during operation. Therefore, the cooling effect of the bearing sleeve 2 and the bearing body 1 is improved.
[0020] Reference Figure 1In a preferred embodiment, by installing a rolling bearing 13 on the inner side of the bearing body 1, and connecting the inner side of the rolling bearing 13 to the outer side of the bearing sleeve 2, rolling friction can replace sliding friction, reducing wear and energy consumption, adapting to the load of the vertical pump, and with lubrication, it can efficiently dissipate heat, assisting the stable operation of the equipment, and avoiding excessive working friction between the bearing body 1 and the bearing sleeve 2. Therefore, the smooth operation of the bearing body 1 and the bearing sleeve 2 is improved. A bearing cover 14 is installed on the outer side of the top of the bearing body 1, and the bearing cover 14 is located on the outer side of the top of the rolling bearing 13. A bearing sleeve nut 15 is installed on the outer side of the top of the bearing sleeve 2, which can fix the position of the rolling bearing 13 to prevent movement. The bearing sleeve nut 15 is a locking component to prevent loosening. The two work together to stabilize the structure, reduce vibration and avoid wear, ensure reliable lubrication circulation, assist the operation of the rolling bearing 13, and avoid positional displacement of the rolling bearing 13 during operation, thus improving the working stability of the rolling bearing 13.
[0021] Reference Figure 1 In a preferred embodiment, locking nuts 16 are installed on both sides of the spiral oil guide bearing bushing 4. The locking nuts 16 are located inside the bearing body 1, which can prevent the components from loosening and moving, avoid vibration from aggravating wear, and ensure stable lubrication circulation. This provides a solid structural foundation for the low-temperature and high-efficiency operation and extended service life of the bearing bushing 2 and the bearing body 1, thus improving the working stability of the bearing bushing 2 and the bearing body 1. A dust cover 17 is installed on the top of the bearing body 1, located on the outside of the shaft body 3. A water baffle 18 is installed on the surface of the shaft body 3, located on the top of the dust cover 17. A breather 19 is installed on the right side of the top of the dust cover 17, which can block and protect the dust, dirt and sewage on the outside of the bearing body 1 and the bearing bushing 2. At the same time, the breather 19 stabilizes the air pressure inside the cavity. The three work together to ensure stable lubrication, maintain working conditions, ensure effective circulating lubrication, reduce failures, and avoid the bearing body 1 and the bearing bushing 2 from failure due to dirt during operation. Therefore, the working protection of the bearing bushing 2 and the bearing body 1 is improved.
[0022] Specifically, the working process or principle of this spiral circulating lubrication vertical bearing body component is as follows: During use, the lower bearing cover 10 is used in conjunction with the external interface to connect the lubricating oil cooling water chamber 11 with the external circulating water body, preparing for the subsequent cooling of the lubricating oil by the lubricating oil cooling water chamber 11. When the external vertical pump rear shaft 3 drives the spiral oil guide bearing bush 4 to rotate, the oil guide spiral groove 6 rotates, increasing the power of the lubricating oil in the bearing cavity, converting the lubricating oil in the bearing cavity into a high-pressure oil flow, which is then transported to the rolling mill along the lubricating oil inlet passage 5. The bearing 13 is fully wetted by high-pressure oil flow, forming a lubricating film to reduce friction and dissipate heat. The lubricating oil then flows along the bearing clearance to the lower bearing body 1, and flows into the bottom lubricating oil chamber 7 through the lubricating oil return hole 8. Cooling water is introduced into the lubricating oil cooling water chamber 11 to quickly remove the heat from the lubricating oil. The cooled lubricating oil re-enters the oil guide spiral groove 6 to start a new cycle. The higher the speed, the faster the cycle, and the better the cooling and lubrication effect. The temperature drops from 90 degrees to 35 degrees, ensuring a bearing service life of more than 8000 hours. During this process, the bearing cover 14 and the locking nut 16 prevent loosening of the fixing components, the dust cover 17 and the water baffle 18 isolate external impurities, the breather 19 balances the air pressure, and the oil level gauge component 9 controls the oil volume, all of which together ensure stable circulation and achieve low-temperature long-life operation.
