A hybrid shaft bearing, a wind generator comprising the hybrid shaft bearing, a use of the hybrid shaft bearing, and a method of operating the hybrid shaft bearing is provided. The hybrid shaft bearing comprises a hydrodynamic friction bearing and a rolling bearing. Both the hydrodynamic friction and rolling bearings cooperate with a support structure and rotatably support a shaft. The hydrodynamic friction bearing is a passive hydrodynamic bearing.

Hybrid shaft bearing, wind generator comprising a hybrid shaft bearing, use of the hybrid shaft

A bidirectional bearing, a drive train, a planetary gear and a wind generator having a bidirectional bearing are provided. A bidirectional bearing comprises an outer bearing shell having a first intermediate bearing shell, which is coupled to the shaft and which cooperates with the outer bearing shell. The bidirectional bearing further comprises a second intermediate bearing shell, which is arranged opposite to the outer bearing shell with respect to the first intermediate bearing shell. The second intermediate bearing shell is configured to take up a first load having a first direction from the first intermediate bearing shell. Furthermore, the first second intermediate bearing shell is configured to receive a second load having a second direction, which is substantially opposite to the first direction. The first intermediate bearing shell receives the second load from the second intermediate bearing shell and is configured to transfer this second load to the outer bearing shell.
