FIELD: machine building.
SUBSTANCE: gas turbine includes a system balancing the rotating part, it includes a balancing weight element and fastener. The balancing weight element is made with first and second holes, wherein first and second holes are made with possibility of detachable installation of the fastener. The fastener ensures connection of the balancing weight element with the rotating part during its installation in the first hole. The fastener is inserted in the second hole after the balancing weight element securing without possibility of detachment from the rotating part. During balancing of the rotating part of the gas turbine the balancing weight element is connected with possibility of detachment with the rotating part in spatially fixed position by the fastener insertion in the first hole of the rotating part. The rotating part balance is checked, and if this is OK, the balancing weight element is secured to the rotating part without possibility of detachment in spatially fixed position. The fastener is inserted in the second hole of the balancing weight element when it is secured without possibility of detachment in spatially fixed position.
EFFECT: group of inventions simplifies balancing of the rotating part of the gas turbine.
