FIELD: mechanical engineering. ^ SUBSTANCE: invention provides dynamic precision balancing of rotors, preferably those design excludes possibility of their balancing at high speeds of rotation. Proposed balancing stand contains bedframe 1 with vertical post 2 on which upper and lower vibrator suspensions, 3 and 4 are secured, suspensions being made identical. Each suspension is essentially single part formed by elastic cantilever plates and solid base. Supports 7 and 8, being conical gas bearings, are secured in suspensions. Rigid base projections are made on solid bases of each vibratory suspension on which force measuring sensors are arranged in contact with elastic cantilever plates. Thin-walled process adapter 12 is installed in supports 7 and 8 inside which rotor 13 under testing is fixed. Inner surface of adapter 12 base support surfaces corresponding to geometry of rotor under balancing which makes it possible to use one and the same expensive gas bearing for rotors of different geometry. Pneumatic accelerating mechanism is arranged in upper gas support 7, and in lower support 8, pneumatic braking mechanism is installed. ^ EFFECT: provision of precision balancing of rotors at slow rotational speeds at maximum accuracy owing to high accuracy of measurement of unbalance. ^ 2 cl, 4 dwg
