The roller sleeve is of a tubular structure with two open ends, and the inner diameter of the middle part of the roller sleeve is smaller than the inner diameter of the two ends of the roller sleeve. The two bearings are arranged at two ends of the inside of the roller sleeve in a one-to-one correspondence mode, and the pin shaft penetrates through the roller sleeve and is fixedly connected with the inner ring of the bearing. And a sealing end cover is arranged on the outer side of each bearing.
The sealing end cover comprises a high-temperature resistant fluororubber material.
The bearing adopts C5 series.
The pin shaft is internally and vertically provided with a first cooling water pipeline, the first cooling water pipeline is arranged along the central line of the pin shaft and penetrates through the pin shaft, and the diameter of the first cooling water pipeline is 16mm.
The pin shaft is provided with an oil guiding groove, the oil guiding groove extends from one end of the pin shaft to the middle of the pin shaft, and the other end of the oil guiding groove is communicated with the outer wall of the middle of the pin shaft.
And a plurality of second cooling water pipelines are arranged on the U-shaped bracket.
The invention has the beneficial effects that:
cooling water of the crystallizer guide roller flows out along the central pipeline after entering the central cooling water channel, so that the cooling circulation process of the cooling water in the crystallizer guide roller is completed, the sealing structure can be reduced, and the risk of cooling water leakage can be reduced.
The bearing mounting position is also provided with a cooling water path, the bearing can be synchronously cooled, the service life of the bearing is prolonged, the bearing adopts C5 series with larger play, and the service life of the bearing is prolonged.
The diameter of the first cooling water pipeline is increased, so that the cooling effect can be improved.
The oil filling groove is formed in the middle of the pin shaft of the guide roller, and oil filling lubrication is carried out on the bearing by utilizing the production pouring gap, so that the service life of the bearing is prolonged.
After the guide roller is changed into a split type structure, the bearing and the roller sleeve only need to be replaced in subsequent maintenance, and the structural body can be reused, so that the maintenance cost is greatly reduced.
The improved efficiency of the guide roller can be improved, the casting blank quality and the service life of the guide roller can be improved, so that the casting blank qualification rate can be improved, and the spare part cost can be reduced.
