BEARING ARRANGEMENT
OThe rotary movement of the rotor is supported by two bearings: the thrust bearing, and the guide bearing.In vertically suspended rotors, the shaft of the rotor transfers the load to the thrust bearing, which is usually placed at the bottom of the rotor and rests on the supporting structure. In this case on the top, on the shaft of the rotor, a guide bearing is mounted. This bearing guides the rotor, keeping it in a vertical position.
As a thrust bearing, spherical roller thrust bearings for carrying significant thrust loads and quite large lateral loads are most often used. This bearing can work with a shaft alignment error of up to 2-3° and can be easily dismantled due to its disjunctive properties. As a guide bearing, radial spherical roller bearings allowing significant shaft movement, carrying large lateral loads and quite significant longitudinal loads arising due to the shaft expansion at high temperature, are most often used.
