AI Technical Summary
During use, the lifespan of the inner and outer rings of the existing casting and rolling mill bearing housings is shortened due to heat transfer, and the heavy weight of the housing makes it difficult to move, affecting the stability and convenience of use.
A bearing housing structure with an annular cavity and a water tank was designed. The bearing and casting roll are cooled by a water circulation system, and the housing is moved by a wire lever and universal wheel structure.
It extends the service life of the bearings, improves the practicality of the bearing housing, and makes the housing easier to move.
