INSTALLATION METHOD OF SPECIFIED MISCOORDINATION ON BUCKET WHEEL OF TURBOMACHINE AND BUCKET WHEEL OF TURBOMACHINE WITH SPECIFIED MISCOORDINATION (VERSIONS) Russian patent published in 2009 - IPC F01D5/16 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to installation method of specified miscoordination on bucket wheel of turbomachine and bucket wheel of turbomachine with specified miscoordination. Installation method of specified miscoordination on bucket wheel of turbomachine for reduction of vibrational amplitude of wheel at forced reaction is defined by that it is specified best value of standard deviation for miscoordination as function of operatinal characteristics of wheel in turbomachine relative to required for wheel reaction in form of maximal vibrational amplitude, and at least partly blades are located with different self-resonant frequency on mentioned wheel so, that mean square deviation of frequency allocation of all blades would be equal to at least mentioned value of miscoordination; herewith mentioned value of miscoordination is defined statistically.

EFFECT: such method and such implementation of bucket wheel provides reduction of maximal reaction of wheel and removing of dependence on always presenting small collateral miscoordination.
