Description

Technical Field

[0001] This utility model relates to the field of bearing housing technology, specifically to a water-circulating cooled bearing housing. Background Technology

[0002] In centrifugal fans, the bearing housing is one of the important components. When the centrifugal fan is working, the motor drives the bearing housing through belt drive. Under the action of the bearing housing, the impeller inside the volute rotates, thereby generating air force. The bearing housing is a key component in the mechanical system used to fix and support the bearing and transmit the load.

[0003] When a bearing housing is in use, the friction generated by the internal bearings during operation produces heat. If this heat is not dealt with in time, the lubrication effect of the lubricating oil at the bearing will decrease as the heat increases, leading to increased wear on the bearing housing and ultimately damage to the bearing inside the housing. Therefore, the bearing housing needs to be cooled down during use.

[0004] Traditional bearing housing cooling methods typically involve installing cooling pipes on the outside of the bearing housing and using cooling water to cool the inside of the bearing housing from the outside. However, the cooling water temperature is difficult to quickly reach the inside of the bearing housing for effective cooling, resulting in poor cooling efficiency. Furthermore, after prolonged use, scale will form on the cooling pipes during heat exchange, affecting the delivery of cooling water. Therefore, we propose a water circulation cooling method for bearing housings. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a water-circulating cooling bearing housing, which can effectively solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] This utility model provides a water-circulating cooled bearing housing, comprising:

[0008] The bearing housing body has two symmetrically distributed fixed seats fixedly connected to its outer side, and a rotating shaft is installed on its inner side.

[0009] The cooling mechanism includes a water tank located next to the bearing housing body. A pump body is installed on the top of the water tank. A water outlet pipe is fixedly connected to the outlet of the pump body. A filter assembly is installed in the middle of the water outlet pipe. Two symmetrically distributed hollow rings are installed at the other end of the water outlet pipe. Heat exchange fins extending into the interior of the bearing housing body are fixedly connected to the inner side of the hollow rings. A return water pipe communicating with the interior of the hollow rings is fixedly connected to the outer side of the hollow rings.

[0010] Preferably, a semiconductor cooler is fixedly connected to the outside of the water tank, and the cold end of the semiconductor cooler extends into the interior of the water tank.

[0011] Preferably, a U-shaped partition for dividing the internal space of the water tank is fixedly connected inside the water tank.

[0012] Preferably, the heat exchange fins are distributed in an annular pattern at equal intervals on the inner side of the hollow ring, and the outer side of the bearing housing body is provided with an annular pattern at equal intervals. The side of the heat exchange fins away from the hollow ring passes through the corresponding insertion hole and extends into the interior of the bearing housing body.

[0013] Preferably, the end of the return water pipe away from the hollow ring passes through the outside of the water tank and communicates with the inside of the water tank, and the two hollow rings are symmetrically fixed on both sides of the bearing seat body.

[0014] Preferably, the inner wall of the hollow ring is fixedly connected with a partition block for dividing the internal space of the hollow ring.

[0015] Preferably, the filtration assembly includes a filter tank installed in the middle of the water outlet pipe, the filter tank is provided with a filter element inside, and the top of the filter tank is threadedly connected with a sealing cap.

[0016] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0017] 1. Through the cooling mechanism, this utility model allows the pump to draw cooling water from the water tank into the hollow ring when the bearing housing body is in use. The cooling water in the hollow ring can quickly exchange heat through the heat exchange fins extending into the bearing housing body, which can rapidly reduce the temperature inside the bearing housing body. The cooling effect is good, and the cooling water after heat exchange can flow back to the water tank for further cooling, allowing it to be recycled and has good practicality.

[0018] 2. This utility model, through the setting of the filter component, can filter the scale generated in the water circulation pipeline due to temperature changes under the action of the filter tank and filter element. The filter element is removed and cleaned regularly to keep the water circulation pipeline clean and avoid the phenomenon of pipeline blockage due to scale. This allows the cooling water to stably and continuously cool the inside of the bearing housing body. Attached Figure Description

[0028] 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, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0029] The present invention will be further described below with reference to the embodiments. Example 1:

[0030] Reference Figure 1-6 The first embodiment of this utility model discloses a water-circulating cooling bearing housing, comprising:

[0031] The bearing housing body 1 has two symmetrically distributed fixing seats fixedly connected to its outer side for securely mounting the entire bearing housing onto the equipment base. A rotating shaft is installed on the inner side of the bearing housing body 1.

[0032] The cooling mechanism 2 includes a water tank 24 located next to the bearing housing body 1. A pump body 26 is installed on the top of the water tank 24 as a power source for cooling water circulation, used to pump cooling water out of the water tank 24. A water outlet pipe 22 is fixedly connected to the outlet of the pump body 26. A filter assembly 21 is installed in the middle of the water outlet pipe 22 to remove impurities that may clog the pipe or wear parts before the cooling water enters the cooling loop. Two symmetrically distributed hollow rings 23 are installed at the other end of the water outlet pipe 22. Heat exchange fins 232 extending into the interior of the bearing housing body 1 are fixedly connected to the inner side of the hollow rings 23. A return water pipe 25 communicating with the interior of the hollow rings 23 is fixedly connected to the outer side of the hollow rings 23 to guide the heated cooling water that has absorbed the heat of the bearing back to the water tank 24.

[0033] Specifically, a semiconductor cooler 242 is fixedly connected to the outside of the water tank 24, and the cold end of the semiconductor cooler 242 extends into the interior of the water tank 24. A U-shaped partition 241 for dividing the internal space of the water tank 24 is fixedly connected inside the water tank 24.

[0034] The U-shaped baffle 241 divides the internal space of the water tank 24 into a relatively independent inlet chamber near the inlet of the return pipe 25 and an outlet chamber near the suction port of the pump body 26. Its main function is to guide the water flow path, ensuring that the water that has been fully cooled by the semiconductor cooler 242 is preferentially drawn by the pump body 26, while allowing the higher-temperature return water to first dissipate heat in the inlet chamber before flowing to the cooling area, thereby improving cooling efficiency and temperature uniformity.

[0035] Specifically, heat exchange fins 232 are distributed in an annular pattern at equal intervals inside the hollow ring 23. The outer side of the bearing housing body 1 has an annular pattern of equally spaced insertion holes 27, the position, number and spacing of which match the heat exchange fins 232. The side of the heat exchange fins 232 away from the hollow ring 23 passes through the corresponding insertion hole 27 and extends into the interior of the bearing housing body 1, ensuring that the fin ends directly contact or are very close to the bearing area that needs to be cooled. The two hollow rings 23 are symmetrically fixed on both sides of the bearing housing body 1, corresponding to the bearing installation positions on both sides, to achieve precise cooling on both sides.

[0036] Specifically, the end of the return water pipe 25 away from the hollow ring 23 passes through the outside of the water tank 24 and is connected to the inside of the water tank 24.

[0037] Specifically, the water is introduced into the inlet chamber formed by the U-shaped baffle 241, allowing the high-temperature return water to enter this area first.

[0038] Specifically, the inner wall of the hollow ring 23 is fixedly connected with a partition block 231 for dividing the internal space of the hollow ring 23.

[0039] The inner wall of the hollow ring 23 is divided by the partition block 231, so that the cooling water can enter from one side and flow to the other side before being discharged, thereby improving the heat exchange effect inside the bearing housing body 1. Example 2:

[0040] Reference Figure 1 and Figure 6 This is the second embodiment of the present invention, which differs from the first embodiment in that:

[0041] The filter assembly 21 includes a filter tank 211 installed in the middle of the water outlet pipe 22. The filter tank 211 contains a filter element 212, and a sealing cap 213 is threadedly connected to the top of the filter tank 211.

[0042] The filter tank 211 is usually cylindrical in shape, and its two ends are connected to the outlet pipe 22 by flanges or threads, etc.

[0043] The filter element 212 is the core component of the filter. Depending on the water quality, different filtration precisions can be selected, such as 50μm or 100μm metal mesh filter element 212, sintered filter element 212 or wire gap filter element 212, etc., to intercept solid impurities such as iron filings, sand particles, and scale in the water, and to protect the pump body 26, the flow channel of the hollow ring 23 and the heat exchange fins 232 from being unobstructed.

[0044] By unscrewing the sealing cap 213, the top opening of the filter canister 211 can be easily opened, allowing the internal filter element 212 to be removed for cleaning or replacement without disassembling the entire filter canister 211. A sealing ring is typically provided between the sealing cap 213 and the top of the filter canister 211 to ensure a tight seal at the connection and prevent cooling water leakage.

[0045] The remaining structure is the same as that in Example 1.

[0046] The workflow of this utility model is as follows:

[0047] When the bearing housing body 1 is in use, the pump body 26 draws cooling water from the water tank 24 and enters the two hollow rings 23 through the water outlet pipe 22. Before entering the hollow rings 23, the impurities in the water can be filtered by the filter assembly 21.

[0048] After the cooling water enters the hollow ring 23, it can quickly cool the bearings on both sides of the bearing housing body 1 through the heat exchange fins 232 that extend into the bearing housing body 1, so that the bearing working area inside the bearing housing body 1 can always maintain a suitable temperature.

[0049] After heat exchange, the cooling water is collected through the return water pipe 25 and then transported back to the water tank 24. Under the action of the semiconductor cooler 242, the cooling water that returns to the water tank 24 is cooled down, so as to achieve the purpose of cooling the bearing housing body 1 by using water circulation.

[0050] Periodically remove the sealing cap 213, take out the filter element 212 inside the filter canister 211, and clean or replace it.

[0051] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
