FIELD: machine building.
SUBSTANCE: weight balance (50) is intended for aircraft turbine engine rotor disk (12, 32). Rotor disk comprises recesses (14, 34) accommodating vanes roots (16, 36) arranged in gaps there between arranged along tangential line to disk (12, 32). Recesses (14, 34) comprise two active side surfaces 4, 4). Weight balance (50) is to be arranged in said gap and comprises two pyramid-shaped end parts. Each of said parts has base, apex and mid part interconnecting two bases of both end parts. Two apices are located along lengthwise axis X. Weight balance (50) comprises two lengthwise planes of symmetry (Y, Z) and (Z, X). All faces (56) of said end parts are identical and have two active surfaces (56, 56) to come in contact with two active side surfaces (4, 4) of relevant recesses (14, 34).
EFFECT: faster and simplified balancing.
