Overload friction clutch, particularly for a wind turbine transmission.

摘要

The overload coupling has a drive disk (1) connected to a drive shaft of the working machine and frictionally clamped between two friction disks (3,4) connected to a drive shaft (6) of the drive machine. Biased expansion bolts (5) are provided to generate the clamping force and a radial bearing (11) is provided for centering the friction disks relative to the drive disk.
