Technical Field
[0001] The utility model relates to the technical field of displacement bearings, in particular to a large arc axially displaceable bearing for a continuous casting machine. Background Art
[0002] Bearings are an important component in modern mechanical equipment. Their main function is to support mechanical rotating bodies, reduce the friction coefficient during their movement, and ensure their rotation accuracy. Axial displacement is also called axis displacement, which is the displacement along the axis. The axial direction is usually for cylindrical objects, that is, the direction of the central axis of rotation of the cylinder, that is, the same direction as the central axis.
[0003] The inventors have discovered in their daily work that, in the process of displacing the bearing, the structure of existing bearings is mostly assembled by interference fit of rollers. When in use, they mostly rely on rollers to withstand axial forces. Since the force that the rollers can withstand is limited, when the bearing is moving axially, the movement of the outer shaft ring is driven by the rollers. When the rollers push the outer shaft ring to move, the load on the outer shaft ring itself will increase. When the load exceeds the threshold that the rollers can withstand, the bearing will separate, which will then lead to bearing damage. Utility Model Content
