METHOD OF THE THREADED ELEMENT LOCKING SCREWED IN INTO THREADED SOCKET, METHOD OF INSTALLATION OF, AT LEAST, ONE TURBINE BALANCING WEIGHT AND TURBINE Russian patent published in 2018 - IPC F16B39/02 G01M1/34 F01D25/00 

FIELD: machine building.

SUBSTANCE: invention relates to a method of the threaded element (3) locking screwed in into the turbine unit (29) threaded socket (2), made in the form of a mounting screw (4). In the method, the screwed in into the balancing weight threaded socket (2) threaded element (3) is flexibly deformed, at least in part, by the tool (10) deformation means (14) such, that to provide its locked position in the balancing weight threaded socket (2). At that, the tool (10) is placed coaxially in front of the threaded element (3), installing the tool (10) tool guide (12) in the threaded element (3) reception-driving recess (11), wherein installed in such a way coaxially in front of the threaded element (3), the deformation means (14) are accelerated in the direction of the threaded element (3), wherein the deformation means (14) are displaced relative to the guiding member (12) installed in the reception-driving recess (11) to deform the threaded element (3) first thread turn from the tool (10) side and / or the balancing weight threaded socket (2) by the deformation means (14) for the threaded element (3) locking in the balancing weight threaded socket (2).

EFFECT: technical result is in preventing of the screws self-loosening to prevent the balancing weights from shifting from the predetermined position.
