Description

Technical Field

[0001] The present invention relates to the technical field of bearing seats, and particularly to a water-cooled bearing seat with temperature difference seal compensation. Background Art

[0002] In modern industrial production, many mechanical devices operate under high-temperature, high-speed or high-load conditions. For example, devices such as large fans, rolling mills, and generators have rotating shafts that bear huge loads during operation, generating a large amount of heat. As a key component for supporting the rotating shaft, the bearing is extremely sensitive to temperature. Excessive temperature will seriously affect its performance and lifespan, and thus threaten the stable operation of the entire mechanical device. As a specially designed mechanical component, the water-cooled bearing seat utilizes an internal cooling system to introduce low-temperature cooling water into the cooling channels inside the bearing seat through the inlet pipe. During the flow of the cooling water, sensible heat transfer occurs with the metal material of the bearing seat, absorbing heat, and then it is discharged through the outlet pipe, forming a closed circulation system. In this way, the temperature of the bearing seat can be maintained within a reasonable range all the time, preventing the internal bearing from being damaged due to high temperature. Therefore, a water-cooled bearing seat is needed to effectively cool the bearing.

[0003] During the operation of the existing traditional water-cooled bearing seat, it mainly relies on circulating the cooling water to the inside of the bearing seat to achieve cooling of the bearing seat through heat exchange. However, in the path where the cooling water is circulated to the inside of the bearing seat, external impurities are extremely likely to mix in. Over time, these impurities accumulate inside the bearing seat, not only changing the flow characteristics of the cooling water flow channel, reducing the heat exchange efficiency, but also possibly causing partial blockage of the cooling channels, seriously affecting the normal circulation of the cooling water, and thus unable to ensure the stable cooling effect of the bearing seat. Summary of the Invention

[0004] The present invention relates to a water-cooled bearing seat with temperature difference seal compensation, which has a slag collection tank. The arc-shaped groove design of the slag collection tank is convenient for collecting impurities in the cooling water. Over time, the impurities precipitate in the slag collection tank. The threaded connection between the external discharge through-hole and the plug makes it simple and easy to clean the impurities. Just use a tool to unscrew the plug through the arc-shaped groove at the bottom of the plug, and the impurities in the slag collection tank can be discharged together with the remaining coolant. After cleaning, tighten the plug again, and the normal operation of the system can be quickly restored, reducing the impact of impurity accumulation on the cooling effect and equipment performance.

[0048] Embodiment Two:

[0049] In the embodiment of the present disclosure, as Figures 1 to 12 shown, the arc-shaped groove design of the slag collection tank 8 can effectively collect the impurities precipitated in the cooling water, which is convenient for centralized cleaning and ensures the normal operation of the cooling system. The arc-shaped pipe grooves respectively and equidistantly connected on the left and right sides of the docking plug groove 5 can optimize the flow direction of the cooling water and improve the cooling efficiency. The anti-leakage rubber frame 12 is made of rubber material. By using its good elasticity and sealing performance, it can effectively compensate for the deformation of components caused by temperature differences and prevent the leakage of the coolant.

[0050] The specific usage mode and function of this embodiment: In the present invention, inside the bearing base 1 and the bearing top cover 4, the inner blocks 10 are respectively fixed by screws. The arc-shaped tubular grooves outside the inner blocks 10 are docked with the slag collection tank 8 and the inner flow tank 9. Then, the four anti-leakage rubber frames 12 are embedded into the inner blocks 10 and the card slots 11 on the bearing base 1 and the bearing top cover 4. By using the characteristics of the rubber material to compensate for temperature deformation and prevent leakage, and then the bearing base 1 is put in place. With the aid of the semi-circular ring-shaped protrusion on its outer wall for auxiliary positioning, the bearing top cover 4 with the same semi-circular ring-shaped protrusion and bolt holes is connected by bolts through the bolt holes to form a closed space. At the same time, after the bearing and the shaft are installed, a sealing plug plate 6 is inserted into the docking plug groove 5 at the docking position of the bearing base 1 and the bearing top cover 4.

[0051] During the cooling process, the coolant is transported to the inside of the bearing housing through the external connecting pipe 15 in cooperation with an external cooling device, and then circulates inside the bearing housing through the arc-shaped tubular grooves of the bearing base 1, the bearing top cover 4 and the matching inner block 10. During the circulation process, the heat inside the bearing housing is carried outwards to dissipate heat from the internal bearing and shaft. During the circulation of the coolant, the slag collecting groove 8 is used to detain impurities in the cooling water to prevent the impurities from circulating inside the bearing housing. After using for a certain period of time, the bottom of the blocking block 3 is removed to connect the external discharge through hole 2 with the outside, facilitating the external discharge of the internal coolant and impurities for convenient use.
