RUNNING WHEEL OF TURBINE EQUIPPED WITH AXIAL FIXATION DEVICE LOCKING BLADES RELATIVE TO DISC Russian patent published in 2014 - IPC F01D5/30 

FIELD: machine building.

SUBSTANCE: turbine running wheel includes a disc, an axial fixation device and many blades including a body, a flange and a fastener. Blades are installed in a circumferential direction of the disc; with that, the fastener of each blade is mounted in a slot that spreads axially between the disc surfaces. At least one of the blades is tightly adjacent to the first locking element of the disc for its locking relative to the disc in the first axial direction. Blade flange includes an axial projection including the second locking element. The axial projection, the second locking element and the disc surface form a groove for receiving the axial fixation device, which faces the axis. When in a folded position, the axial fixation device adjoins the second locking element in the first axial direction and the front disc surface in the second axial direction that is opposite to the first one. The other invention of the group refers to a turbomachine containing the above running wheel.

EFFECT: inventions allow reducing vibration of running wheel blades.
