DEVICE FOR FIXING THE SHOULDER AND TURBOMACHINE, WHICH CONTAINS THIS DEVICE Russian patent published in 2017 - IPC F01D5/30 

FIELD: machine engineering.

SUBSTANCE: blade fixing device fixing member to a fixing groove of the impeller includes a coupler and the sheet. The adapter is located between the blade and the impeller and has a fixing groove, a fixing element complementary blade and fastener mounting recess complementary impeller. Pad has a fixing element complementary to the impeller mounting groove, and a hook member disposed at the radially inner end of the lining and the fastening element for interacting with the adapter. A hook element is axially relative to the adapter and holds the lining. The fixing blade element is inserted axially into the mounting groove of the adapter, and the pad interacts with the first surface of the adapter. Assembled adapter fixing member and the fixing element laths are axially inserted in the fixing groove of the impeller. Another invention of the group relates to a turbomachine, which containes the above mentioned blade mounting device.

EFFECT: group of inventions allows you to set in the mounting groove of the impeller blades with a shank in the form irrelevant to this slot.
