TURBINE RUNNER AND TURBOMACHINE CONTAINING SUCH RUNNER Russian patent published in 2014 - IPC F01D5/30 

FIELD: engines and pumps.

SUBSTANCE: turbine runner contains a disc and lots of blades installed in its circumferential direction. Each blade has a flange, a fin and a fastener installed in disc slot passing inside from the flange and axially along the whole distance between disc side surfaces. Disc slots are divided by disc teeth. The blades are fixed axially on one of side surfaces of the disc by clamping plate with teeth on periphery. Plate teeth press blades fasteners sidewise non-contacting disc side surface. Radial size of clamping plate provides teeth pressure application only to lower sections of the blades fasteners. The blades are fixed axially on the other side surface of the disc by relief sections protruding radially from the disc teeth and pressing relief sections formed under blades flanges in places behind against side surfaces of the blades fasteners located on the mentioned other side surface of the disc. The other invention of the group refers to turbomachine containing the above runner.

EFFECT: group of inventions allows reducing overall dimensions of the device for axial fixation of the turbine runner blades.
