Abstract (en)
The turbine and/or compressor (1) has guide blades (3) rotatably supported at a blade bearing ring (2), and an adjusting ring (7) for adjusting the guide blades, where the adjusting ring is rotatably supported at the bearing ring by guide rollers (8). One of the guide rollers is rotatably supported at the bearing ring, and a securing device (9) is provided at the guide rollers for rotatably fixing the guide rollers at the bearing ring. The securing device is formed as a slotted pin, and the adjusting ring has recesses at an inner circumference. An independent claim is also included for a method for mounting a geometry variable turbine and/or compressor.
