Abstract

A system (1) for measuring rotational imbalances for a rotating workpiece (10) balancing machine is provided, wherein the workpiece (10) defines a rotation and a force (F) determined by imbalances in at least one plane (1a) during rotation, and the system (1) comprises a fixed support (2), a movable support (3) connected to the fixed support (2), configured to allow at least part of the workpiece (10) to be accommodated, and configured to allow micro-movements relative to the fixed support (2) along the plane (1a) proportional to the force (F), sensing means (4) operatively connected to the fixed support (2) and to the movable support (3) and suitable for sensing forces (F), and clamping means (5) loosely constraining to the movable support (3) and to the fixed support (2) in order to permit said relative micro-movements between said movable support (3) and said fixed support (2) exclusively along a predetermined trajectory (5a) lying in said plane (1a), along said predetermined trajectory (5a) and including opposing means (50) realizing a moment opposite to the moment generated by said workpiece (10) when placed on said movable support (3).
