| description | The invention discloses a dynamic balance device of a cantilever turbine rotor, and relates to the field of dynamic balance testing. Two groups of support swing frame tools; the blowing mechanism is used for blowing blades of the cantilever turbine rotor; the rotating speed measuring mechanism is used for rotating speed; the supporting swing frame tool comprises a base; the swing frame is mounted on the base, and two supporting rollers are arranged on the swing frame; the pressing plate is detachably installed above the swing frame, an anti-warping roller is arranged on the pressing plate, and the diameter of an inscribed circle formed by the anti-warping roller and the two supporting rollers is the same as the diameter of a rotating shaft of the cantilever turbine rotor; and the vibration sensor is arranged on the base or the swing frame. The problem that an existing cantilever turbine rotor is prone to warping during dynamic balance and the problem that a measurement result is unstable during belt driving a |
