Description

Technical Field

[0001] The present invention relates to the technical field of bearing boxes, and more particularly to a bearing box with a dual cooling system. Background Art

[0002] As the name suggests, a bearing housing is a casing or structural component used to house, support, and protect bearings. It is a fundamental and critical component of rotating equipment (such as motors, pumps, fans, gearboxes, and compressors). It provides precise and stable mounting for bearings, ensuring they correctly position and support the rotating shaft (rotor) radially and axially. Bearings inevitably generate heat during operation. If this heat is not dissipated promptly and effectively, the bearing temperature will continue to rise. The inner and outer rings, rolling elements, and bearing housing itself are all made of metal and expand when heated.

[0003] Currently, the simplest method relies on natural convection of air on the outer surface of the bearing housing to dissipate heat. Alternatively, a fan may be installed near the bearing housing or on the bearing housing shell to force air to flow over the heat dissipation surface. However, natural heat dissipation or fan heat dissipation can be inefficient due to the installation environment. Heat can easily accumulate, leading to excessive temperatures, which can seriously damage lubricant performance, cause harmful thermal expansion, and accelerate material aging and wear. Therefore, a bearing housing with a dual cooling system is provided. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a bearing box with a dual cooling system, aiming to solve the problems raised in the above-mentioned background technology.

[0005] The present invention provides the following technical solution: a bearing housing with a dual cooling system, comprising a reinforced shell, wherein two cooling assemblies are embedded in the reinforced shell;

[0006] The cooling assembly includes a resistance member arranged in the reinforced shell, one end of the resistance member is provided with a water distribution hollow member, and a plurality of elastic storage bags are distributed on the water distribution hollow member and are all connected to the water distribution hollow member;

[0007] The outer sides of the multiple elastic storage bags are all covered with silicone grease sleeves, and one end of two adjacent elastic storage bags is provided with a first diversion hose, and the other end is provided with a second diversion hose, and the first diversion hose and the second diversion hose are both connected to the elastic storage bags;

[0008] One end of the reinforced shell is embedded in a limiting ring, and a plurality of circulation guide seats are distributed in the middle of the limiting ring, and a plurality of air gathering cavities are opened on each of the circulation guide seats, and a plurality of truncated cone holes are opened through the inner walls of the air gathering cavities.

The bosses comprise a through-hole, a screw bolt, and a nut. The bosses comprise a through-hole, a screw bolt, and a nut. The bosses comprise a through-hole, a screw bolt and a nut. The bosses comprise a through-hole, a screw bolt and a nut.

[0010] Technical effects and advantages of the present invention:

[0011] 1. This invention utilizes a combination of a hollow water-distributing element and an elastic storage bag to evenly distribute the cooling medium to the outside of the bearing. The elastic storage bag expands under pressure and adheres to the bearing surface, filling the gap and achieving wrap-around cooling. This improves cooling efficiency compared to traditional air cooling. The silicone grease sleeve further enhances heat conduction, reducing the operating temperature of the bearing.

[0012] 2. The present invention forms an airflow focusing structure through the air collection cavity and frustum hole of the circulation guide seat. The frustum-shaped cross-section increases air velocity, making it easier for airflow to impact the heating area of ​​the bearing. Furthermore, the guide box and quick-connect connector form a closed structure to circulate water, which, in conjunction with the air-cooled radiator installed in the cylinder, creates forced convection, improving heat dissipation and cooling efficiency and effectiveness.

[0013] 3. After the elastic storage bag is hydraulically expanded, it fits tightly against the bearing surface through the silicone grease sleeve, filling the gap. Simultaneously, the hinged rod drives the resistance member to adjust, allowing the cooling assembly to adapt to bearings of different diameters without replacing the housing.

[0014] 4. This invention utilizes a reinforced frustum-shaped design at the top of the housing and exhaust slots to facilitate air flow and heat dissipation, preventing the accumulation of hot air. The stepped arc structure of the abutment and water-distributing hollow member ensures axial positioning accuracy during bearing installation. The bearing and abutment serve as support points, while the elastic storage bag automatically conforms to the bearing, ensuring cooling efficiency.

[0015] To summarize, the cooling medium can be evenly diverted to the outside of the bearing. The elastic storage bag expands under pressure and fits the bearing surface, filling the gap to achieve wrap-around cooling. An airflow focusing structure is formed through the air gathering cavity and the frustum hole of the circulation guide seat. The frustum-shaped cross-section increases the air flow rate, making it easier for the airflow to impact the heating area of ​​the bearing. On this basis, the guide box and the quick-connect connector form a closed structure to allow water to flow, and cooperate with the air-cooled radiator installed in the cylinder to form forced convection, thereby improving the heat dissipation and cooling efficiency and effect.

DETAILED DESCRIPTION

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] As attached Figure 1 -Attached Figure 9 The illustrated bearing housing with a dual cooling system utilizes a cooling assembly mounted on a reinforced housing 1 to evenly distribute the cooling medium to the outside of the bearing. The elastic storage bag 4 expands under pressure and adheres to the bearing surface, filling the gap and achieving wrap-around cooling. The airflow focusing structure is formed by the air collection cavity 13 of the circulation guide seat 12 and the frustum hole 14. The frustum-shaped cross-section increases air velocity, making it easier for airflow to impact the heating area of ​​the bearing. Furthermore, the guide box 16 and the quick-connect connector 17 form a closed structure to circulate water, which, in conjunction with the air-cooled radiator within the mounting tube 21, creates forced convection, improving heat dissipation and cooling efficiency. The specific structural configuration of the assembly is as follows:

[0029] The cooling assembly includes a resisting member 2 disposed in a reinforced housing 1, one end of which is provided with a water-distributing hollow member 3, and a plurality of elastic storage bags 4 are distributed on the water-distributing hollow member 3 and are all connected to the water-distributing hollow member 3;

[0030] As attached Figure 3 、 5 As shown in Figures 7 and 8, the cooling medium is transported to the water distribution hollow member 3 and is divided through each elastic storage bag 4. The elastic storage bag 4 expands and deforms due to pressure, so that the elastic storage bag 4 fits the outer side of the bearing. The expansion and deformation of the elastic storage bag 4 fills the gap on the outer side of the bearing, thereby achieving the function of wrapping cooling of the bearing;

[0031] The outer sides of the multiple elastic storage bags 4 are all covered with silicone grease sleeves 5, and one end of two adjacent elastic storage bags 4 is provided with a first diversion hose 6, and the other end is provided with a second diversion hose 7, and the first diversion hose 6 and the second diversion hose 7 are both connected to the elastic storage bags 4;

[0032] As attached Figure 3 、 5 As shown in Figures 7 and 8, the silicone grease sleeve 5 is provided to facilitate better heat conduction to the medium transported by the elastic storage bag 4 during heat conduction and heat dissipation of the bearing. At the same time, each elastic storage bag 4 is connected via the first guide hose 6 and the second guide hose 7 to facilitate the circulation of the cooling medium in each elastic storage bag 4, facilitating heat conduction cooling during the circulation of the medium.

[0033] One end of the reinforced shell 1 is embedded with a limit ring 23. A plurality of circulation guide seats 12 are distributed in the middle of the limit ring 23. Each circulation guide seat 12 is provided with a plurality of gas gathering cavities 13. The inner walls of the plurality of gas gathering cavities 13 are penetrated with a plurality of frustum holes 14. A spring 15 is provided on the outer side of the circulation guide seat 12. The vertical cross-section of the frustum hole 14 is set to be frustum-shaped.

[0034] As attached Figure 1 and 2 As shown, the circulation guide seat 12 can be displaced toward the axial center point of the limiting ring 23 due to the elasticity of the spring 15 itself, so that the circulation guide seat 12 can abut against the outside of the bearing or the rotating shaft, and the conical hole 14 facilitates the airflow to be transported to the air gathering chamber 13, and the airflow is gathered through the air gathering chamber 13 for air cooling, and the conical cross-section of the conical hole 14 is used to gather the airflow, so that the airflow is more targeted when it is ejected.

[0035] A water tank 8 is provided on the side of the resistance member 2 away from the water distribution hollow member 3, and a plurality of slots 9 are formed through the water tank 8;

[0036] As attached Figure 3 、 5 The water tank 8 is provided to store cooling water, and the notch 9 facilitates air flow through the water tank 8 to discharge the heat of the cooling water exchanged in the water tank 8.

[0037] A micro water pump 10 is provided on one side of the water tank 8, and a water distribution pipe 11 is provided at the output end of the micro water pump 10. The water distribution pipe 11 is installed on the outside of the water distribution hollow member 3 by bolts;

[0038] As attached Figure 5 and 7As shown, the micro water pump 10 is started to transport the cooling water in the water tank 8 through the hose to the water distribution pipe 11. The water distribution pipe 11 transports the cooling water to the water distribution hollow member 3 and the elastic storage bag 4. At the same time, a conduit is installed at one end of the water distribution hollow member 3 and the conduit is connected to the water tank 8, so that the cooling water in the water distribution hollow member 3 and the elastic storage bag 4 flows back to the water tank 8 through the conduit.

[0039] A flow guide box 16 is provided on both sides of the circulation guide seat 12, and a quick-connect connector 17 is provided at one end of each flow guide box 16. Both flow guide boxes 16 are connected to the circulation guide seat 12.

[0040] As attached Figure 2 As shown, the cooling medium can be transported to the guide box 16 through a water pump and a conduit through a quick-plug connector 17. After the cooling medium flows in the circulation guide seat 12, it is gathered through another guide box 16 and discharged by the quick-plug connector 17. The guide box 16 and the quick-plug connector 17 allow the cooling medium to flow in the circulation guide seat 12, so that the air flow is ejected through the frustum hole 14 and cooled, thereby improving the efficiency and effect of heat conduction and heat dissipation.

[0041] The end of the reinforced housing 1 away from the limiting ring 23 is embedded with a mounting plate 18, and a hinge rod 19 is hinged on the mounting plate 18. One end of the hinge rod 19 extends to the end of the resistance member 2 and is hinged to the resistance member 2.

[0042] As attached Figure 5 As shown, the mounting plate 18 serves as a support point so that the hinged rod 19 can rotate along the axis point at which the hinged rod 19 is connected to the mounting plate 18, and the resistance member 2 can rotate along the axis point at which the resistance member 2 is connected to the hinged rod 19, making it easy to adjust the angle of the resistance member 2 so that the resistance member 2 and the water-distributing hollow member 3 can be gathered toward the axis point of the reinforced shell 1 and the water-distributing hollow member 3 and the elastic storage bag 4 can be wrapped around the outside of the bearing, which not only facilitates the loading and unloading of the bearing but also can adapt to bearings of different sizes.

[0043] The connection between the mounting plate 18 and the hinge rod 19 and the connection between the hinge rod 19 and the abutment 2 are respectively provided with screw rods 20 , and the screw rods 20 pass through the reinforced housing 1 and extend to the outside of the reinforced housing 1 ;

[0044] As attached Figure 1 、 3 , 5 and 6, the angle of the resistance member 2 and the hinge rod 19 is adjusted by rotating the screw rod 20, and then the screw rod 20 is locked by the self-locking nut, so that the resistance member 2 and the hinge rod 19 are fixed after the angle adjustment, ensuring the stability of the resistance member 2 after the angle adjustment, and further, by opening an offset opening on the outer side of the reinforced shell 1 to offset the interference between the screw rod 20 and the reinforced shell 1, it is convenient to adjust the angle of the hinge rod 19 in the reinforced shell 1.

[0045] Mounting tubes 21 for mounting an air-cooled radiator are provided on both sides of the surface of the reinforced housing 1, and the mounting tubes 21 are located on one side of the water tank 8;

[0046] As attached Figure 1 and 4 As shown, the air-cooled radiator is installed in the installation cylinder 21, and the airflow delivered by the air-cooled radiator is gathered by the installation cylinder 21, and the airflow is ejected through the installation cylinder 21 so that the airflow passes through the slot 9 to dissipate heat to the water tank 8.

[0047] The outer side of the reinforced shell 1 is provided with a plurality of exhaust slots 22. The vertical cross-section of the top of the reinforced shell 1 is set to be a truncated cone. The vertical cross-sections of the abutment member 2 and the water-distributing hollow member 3 are both set to be arc-shaped, and the abutment member 2 and the water-distributing hollow member 3 are distributed in a stepped manner.

[0048] As attached Figure 1 、 3 As shown in Figures 4 and 5, the installation tube 21 is arranged to facilitate air circulation, and the resistance member 2 and the water-distributing hollow member 3 are distributed in a stepped manner, which makes it convenient for the resistance member 2 to first resist the outside of the bearing and then the water-distributing hollow member 3 to wrap the bearing, ensuring the stability of the bearing installed in the reinforced shell 1.

[0049] The detailed operating principle is as follows: After the micro-water pump 10 is activated, it pumps the cooling water from the water tank 8 through a flexible hose into the water distribution pipe 11. The water distribution pipe 11 evenly distributes the coolant to the water distribution hollow member 3. The curved channel of the water distribution hollow member 3 directs the coolant into the elastic storage bag 4. Each elastic storage bag 4 is connected to the inlet of the adjacent bag via a first guide hose 6, and to the outlet via a second guide hose 7, forming a series liquid cooling network. During the heat exchange process, the heat from the bearing is transferred to the cooling water within the bag through the silicone grease sleeve 5. The heated cooling water circulates between adjacent elastic bags through the first and second guide hoses 6 and 7, balancing the heat dissipation load. After absorbing the bearing heat in the elastic storage bag 4, the cooling water returns to the water tank 8 through the conduit at the other end of the water distribution hollow member 3, forming a closed loop.

[0050] When cooling water flows into the elastic storage bag 4, the bag body is expanded by hydraulic pressure, and the outer silicone grease sleeve 5 fits tightly against the bearing surface; the screw 20 adjusts the angle of the hinged rod 19, which can synchronously drive the resistance member 2 to translate and resist on the bearing, so that the wrapping force of the elastic storage bag 4 can adapt to different bearing sizes.

[0051] Furthermore, if Figure 2As shown, the cooling water can be transported to the guide box 16 and the circulation guide seat 12 through an external water pump and pipeline for secondary heat conduction and heat dissipation. The guide box 16 and the quick connector 17 are connected through various pipes to form a closed water circulation loop: one end of the quick connector 17 is connected to the external water source, and the other end is connected to the return pipe, so that the cooling water continues to flow in the guide box 16, the circulation guide seat 12 and the guide box 16; at the same time, the air-cooled radiator in the installation cylinder 21 is as shown in the attached figure. Figure 4 A directional airflow is generated, which enters through the exhaust slot 22 of the reinforced shell 1, a part of which passes through the slot 9 of the water tank 8 to cool the water in the water tank, and the other part enters the air gathering cavity 13 of the circulation guide seat 12 to exchange heat with the cooling water in the guide box 16.

[0052] The airflow is transported through the truncated cone hole 14 to the air collecting chamber 13 of the circulation guide seat 12, where it converges and is ejected through the truncated cone hole 14 on the inner wall. The truncated cone hole accelerates the airflow and directs it to the outer ring of the bearing. The hot air is discharged through the exhaust slot 22 on the outside of the reinforced shell 1. The air-cooled radiator in the mounting tube 21 sends air toward the water tank 8. When the airflow passes through the slot 9, it removes the heat from the surface of the water tank 8, forming a secondary cooling for the cooling water. The truncated cone design at the top of the reinforced shell 1 guides the airflow toward the exhaust slot 22 to prevent the accumulation of hot air inside.

[0053] The airflow then enters the circulation guide seat 12. The vertical cross-section of the frustum-shaped hole 14 is frustum-shaped. According to the principles of fluid mechanics, the airflow increases in velocity as it passes through the hole due to cross-sectional contraction. The airflow is further concentrated by the air collection cavity 13, which directs the airflow to the heat-concentrated areas of the bearing, such as the contact points between the rolling elements and the raceways. This improves the cooling efficiency of the bearing hot spots compared to conventional circular holes.

[0054] By rotating the screw 20, the hinge rod 19 is rotated with the mounting plate 18 as the fulcrum, driving the resistance member 2 to move toward the axis, and the water distribution hollow member 3 and the elastic storage bag 4 then wrap around the bearing; after adjusting to the appropriate position, tighten the screw 20 and fix the angle with the self-locking nut;

[0055] The spring 15 provides a buffering force to the circulation guide seat 12 to adapt to the slight displacement of the bearing or the shaft during operation.

[0056] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
