FIELD: physics. ^ SUBSTANCE: dynamic balancing of gyroscope containing rotor 1 on ball bracket and angle transmitter 3, initially provides marking 4 of rotor revolution surface. Rotor is driven to generate signal corresponding to rotation. Then this signal is compared to modulation amplitude of angle transmitter signal. Marking position within rotor revolution surface is changed so that to provide match of rotation signal to maximum modulation amplitude of angle transmitter signal. Then test amount of material is removed from marking and opposite point symmetric relative to mass axis plane. Change of modulation amplitude of angle transmitter signal shows identity of removed material points. Reducing amplitude material proceeds to be removed until misbalance is compensated. If amplitude is increased, material is removed from opposite to the chosen points, however symmetrically relative to mass axis plane. ^ EFFECT: increased accuracy of gyroscope balancing by misbalance compensation. ^ 4 cl, 3 dwg |
