Abstract: A turbocharger has a regulating unit for controlling the output of the turbocharger. The regulating unit can be adjusted by an actuator. The actuator is connected to the regulating unit by way of an actuating member and a lever. The actuating member and the lever are interconnected by way of a screw-nut element.

Abstract: A method adjusts axial play of a journal mounted in a bearing. A bearing axis defines a z-direction. A positive z-direction points from first to second bearing ends. The journal inserted into the bearing in the positive z-direction is moved to a first form-locking engagement in the positive z-direction between journal and bearing. A spacer at the second end defines axial play. A bushing is placed onto a journal segment protruding from the bearing at the second end in the positive z-direction. A form-locking and/or force-locking connection is established between bushing and journal by deforming the bushing and locating the spacer along the z-direction between bushing and second end. The spacer contacts the bushing and second end. The spacer is removed. A device having a bearing and a journal mounted and relatively movable therein within axial play is also provided.

Abstract: An exhaust-gas turbocharger has a turbine housing and a waste-gate valve of a ball-cock configuration which is arranged therein. The actuating crank of the waste-gate valve has a crank arm, to which the closing element is fastened, and a crank spindle which is connected integrally to the crank arm and is mounted in the turbine-housing wall. A stop shoulder for sealing the crank-spindle bearing and a flexural-stress relief pocket are provided in the transition region between the crank spindle and the crank arm, as a result of which the sealing action of the crank-spindle bearing and a more uniform distribution of flexural stresses in the transition region between the crank arm and the crank spindle are brought about and therefore an increased service life of the actuating crank is ensured with a simultaneously economical configuration.
