  • Rotatable shaft balancing machine and method with automatic flexible shaft balancing equipment
    Patent number: 6694812
    Abstract: Machine and method for dynamically balancing rotatable shafts featuring positioning and welding equipment that is controlled by an electronic control unit that determines the imbalance of a rotating shaft and the amount of weight required at predetermined balance planes associated with misalignment joints of the shaft. The positioning and welding equipment is moved along a rail of the machine parallel with the shaft mounted therein into precision points and the welding gun moves into a welding position in which the shaft is griped by the welder and the correction weight is welded at the correction point on the shaft in the correction plane. In a second embodiment, balancing is achieved by removing calculated amount of materials at points on the shaft determined by the electronic control unit.
