摘要

The rotor bearing (21) has a multi-row roller bearing with two rows of bearings, which have multiple rolling bodies. One of the rows of bearings is formed by a spherical roller bearing series, where other row of bearings is formed by a self-aligning ball bearing row. Pressure lines of the both rows of bearings are arranged in an axial section in axial symmetrical manner.
