FIELD: machine building.
SUBSTANCE: turbine plant comprises rotary machine (12, 14, 24) and balance weight (78). Rotary machine comprises spinning component (62) with groove (76) with base (84) and two inclined sides (86) converging in first direction (66) from base (84) to make opening (92). Balance weight (78) is arranged in said groove (76) and has body, first pair of inclined sides (94) converging in first direction and separated by first spacing (98), and second pair of inclined sides (100) converging in said first direction (66) and separated by second spacing (101), larger than said first one. Every side of first pair of inclined sides comprises flat section 96 to allow decrease in spacing (98) between sides (94). Balance weight can pass through said opening into groove (76) and turn for interaction of said inclined sides (86) with second pair of balance weight inclined sides (100).
EFFECT: simplified design of groove and balance weight.
