Abstract

An adjusting device is provided for pivoting blades of a rotor via a transmission that is actuatable by a co-rotating, axially-displaceable actuating shaft. The adjusting device includes a roller bearing having a first side or ring that is attachable to the actuating shaft and a second side or ring connected with an actuating body that is non-rotatably supported in a support body. The adjusting device further includes a screw drive that axially displaces the actuating body within the support body to thereby linearly actuate the transmission.
