Oscillating support mechanism for carrying a load

摘要

The drive control for an oscillating arm (2, 6, 7, 8) comprises a drive system and an equilibrating device (4) for the force especially gravity, acting on the arm. The equilibrating device applies a sinusoidal compensating couple to the axle (9) of the oscillating arm, regardless of the angle of pivoting ( alpha ) of the arm. The drive (3) produces a constant effort regardless o the angular position of the arm.
