Three-row cylindrical roller slewing bearings are used for ladle turntables

The steel ladle turntable is a device used to rotate the ladle out or into the pouring position. It is mainly composed of a tower base, a rotating body, a transmission device, a lifting arm, a lifting hydraulic cylinder, a slewing bearing device, etc. The missing equipment is also heavy-duty, low-speed running equipment. Today we will talk about the application of slewing bearing in ladle turntable.

Ladle turntables generally use three-row cylindrical roller slewing bearings. For slewing bearings with such a structure, the axial load and radial load are borne by different rollers, and the axial load and overturning moment are borne by two sets of rollers placed horizontally on the axis. The radial load is borne by a set of rollers whose axis is placed vertically. The advantages of this are: first, it has the function of self-aligning, which can avoid the problem of deflection and deformation to the greatest extent because the guide roller is carried by a large load-to-weight ratio; second, it has superior impact resistance and can withstand large impact loads.

The ladle turntable can hold a ladle on two lifting arms at the same time, one for pouring and the other for pouring. The turntable is rotated by the ladle turntable slewing bearing, the slewing bearing is fixed on the bottom tower seat by inner ring bolts, and the outer ring is connected to the upper equipment by bolts. Therefore, the load and overturning moment on the slewing bearing are transmitted to the lower part of the equipment and the foundation through the connecting bolt, so that the bolt becomes one of the important parts of the whole. How to ensure the reliability of bolted connection has always been the focus of attention during the installation of slewing bearings.
