FIELD: measuring engineering.
SUBSTANCE: rotatable table comprises platform mounted on the shaft, servosystem provided with device for control of angular velocity, amplifier, actuating device, feedback device, and balancing device mounted on the shaft and provided with the first and second disks, first, second, and third rings, and connecting rods provided with weights. The faces of the first and second disks are interconnected and provided with ring grooves. The first ring is mounted on the second disk. The second ring enters the first ring. The third ring abuts against the second ring. The connecting rods are arranged along the radius to the axis of the shaft and secured to the outer surfaces of the first and second disks by means of first yoke from one side and to the first and second rings by means of the second yoke from the other side. The connecting rods are arranged over the periphery at different angles with respect to each other.
EFFECT: enhanced precision of angular velocity control.
