Description

Technical Field

[0001] The utility model belongs to the technical field of bearing seats, and in particular relates to a water-cooled bearing seat. Background Art

[0002] In the production process of steel and other materials, continuous casting is a commonly used casting method, that is, molten steel continuously passes through a water-cooled crystallizer, and is continuously pulled out from the outlet below the crystallizer after solidifying into a hard shell. It is cooled by spraying water and cut into billets after it is completely solidified. This process is usually carried out in a continuous casting machine. The continuous casting roller, as the core component of the continuous casting equipment, is mainly used in production to maintain the solidification of the billet and support the billet with a very thin solidification layer. Both ends of the continuous casting roller need to be supported and installed with bearings, and the bearings need to be fixed with bearing seats.

[0003] In the prior art, a Chinese utility model patent with authorization announcement number CN214063585U discloses "a bearing seat for a high-temperature resistant continuous casting roller that is easy to install", including a mounting base and a bearing base, wherein the upper surface of the mounting base is fixedly connected to a bearing upper seat, the upper surface of the bearing upper seat is provided with a main groove, an adapting groove is provided in the main groove, a fixing rod is slidably connected in the adapting groove, and a secondary groove is provided on the lower surface of the bearing base.

[0004] Although the bearing seat of the prior art can perform water cooling on the bearing base, it cannot perform water cooling on the bearing upper seat, and cannot dissipate heat from the bearing. Since the continuous casting roller is heavy, a large centrifugal force will be generated during operation to continuously impact the bearing and the bearing upper seat, which can easily cause thermal deformation of the bearing and the bearing upper seat.

[0005] In order to solve the above problems, a water-cooled bearing seat is proposed in the present application. Utility Model Content

[0012] As a preferred technical solution of the utility model, a plurality of heat dissipation fins evenly spaced along the circumferential direction are fixed in the first semicircular water channel and the second semicircular water channel, and water permeable holes are opened on the heat dissipation fins.

[0013] As a preferred technical solution of the utility model, the outer side surface of the heat dissipation fin is an arc-shaped surface and coincides with the inner walls of the first semicircular hole and the second semicircular hole.
