[0002] The machine is mainly used for gas separation and material screening in the lime production process. The performance of the bearing seat is directly related to the stability and operation efficiency of the entire system. Among them, the lubrication and sealing performance of the bearing seat are particularly important because it is related to the service life and production safety of the equipment.

[0003] In the traditional design of water-cooled bearing seats, the lubricating oil inside the bearing body needs to enter the bearing through the cavity-through oil path. However, there are certain limitations in the casting process of this oil path structure. Specifically, it is manifested in the following aspects:

[0004] In the traditional process, in order to achieve the penetration of the oil path, it is often necessary to cast a solid column inside the bearing seat. This design not only reduces the effective area for water flow, resulting in a decrease in water flow and a reduction in the water-cooling effect, but also increases the casting difficulty and has high requirements for the casting process. Moreover, the design of the solid column is prone to defects such as shrinkage cavities and slag inclusions during the casting process, affecting the strength and sealing performance of the bearing seat.
