Abstract
At least one of a variable turbine geometry and a variable compressor geometry for an exhaust gas turbocharger may include a housing including a first housing wall and a blade bearing ring having at least one guide blade rotatably mounted thereon. A control lever may be included for adjusting the at least one guide blade between a closing position and an opening position. An actuating shaft may be connected to the control lever in a rotationally fixed manner along a rotation axis. The actuating shaft may be rotatably mounted on the housing via a passage opening disposed in the first housing wall. The actuating shaft may directly support itself on the first housing wall in the passage opening.

At least one of a variable turbine geometry and a variable compressor geometry for an exhaust gas turbocharger, comprising:
- a housing including a first housing wall,
- a blade bearing ring including at least one guide blade rotatably mounted thereon,
- a control lever for adjusting the at least one guide blade between a closing position and an opening position,
- an actuating shaft connected to the control lever in a rotationally fixed manner along a rotation axis, the actuating shaft rotatably mounted on the housing via a passage opening disposed in the first housing wall, and
- wherein the actuating shaft directly supports itself on the first housing wall in the passage opening.
An exhaust gas turbocharger, comprising:
- at least one of a variable turbine geometry and a variable compressor geometry, the at least one of the variable turbine geometry and the variable compressor geometry including:
- a housing including a first housing wall and a second housing wall, the first housing wall together with the second housing wall at least partially defining a housing interior;
- a blade bearing ring including at least one guide blade rotatably mounted thereon;
- a control lever for adjusting the at least one guide blade between a closing position and an opening position;
- and
- an actuating shaft connected rotationally fixed to the control lever and being rotatable along a rotation axis, wherein the actuating shaft is rotatably mounted on the housing via a passage opening disposed in the first housing wall and a recess disposed in the second housing wall, the second housing wall disposed opposite the first housing wall with respect to the rotation axis, wherein the actuating shaft is directly mounted on the first housing wall in the passage opening.
