Abstract:
1. A mounting device for mounting articulated shafts to be balanced in a balancing machine comprising a bearing frame and a frame upper part, which is mounted on the bearing frame so as to be able to oscillate via spring bars and includes a rotor mount having a horizontally arranged axis of rotation and adapted for rotatable mounting of one end of a horizontally arranged articulated shaft to be balanced in said balancing machine, and a motor for rotatably driving the rotor mount, wherein the spring bars are aligned parallel to the axis of rotation of the rotor mount and equal numbers of the spring bars are arranged in each one of two parallel vertical planes which are arranged on opposite sides of and at identical distances from the axis of rotation of the rotor mount, wherein the spring bars of one plane are arranged so as to be symmetrical to those of the other plane and at least two groups of at least two spring bars, one at a distance from the other, are provided in each plane and each spring bar has an elongated, slender shape such that its rigidity in the axial direction is at least 100 times greater than its radial flexural rigidity.
