METHOD FOR BALANCING A CYLINDER, ROLL OR EQUIVALENT PART WITH A THIN MANTLE AND BALANCED CYLINDER, ROLL OR EQUIVALENT PART WITH A THIN MANTLE

摘要

The invention relates to a method for balancing a cylinder, roll or equivalentpart with a thin mantle intended to be revolving. Themethod comprises the following steps: in the method, the errors in thecircumferential deflection line of the mantle (25) of the cylinder (10),roll or equivalent part with a thin mantle are measured, and dynamic unbalanceis determined, locations and magnitudes of counterweights(20) necessary for balancing are determined based on the deformations anddynamic unbalance arising from the errors in the deflection lineof the mantle (25), and the counterweights (20) are fixed to the inner face ofthe mantle (25) of the cylinder (10), roll or equivalent part witha thin mantle in order to compensate for the errors in the circumferentialdeflection line and, thus, to eliminate the dynamic unbalance. Theinvention also relates to a balanced cylinder, roll or equivalent part with athin mantle which is intended to be revolving. Counterweights(20) of magnitudes necessary for balancing are fitted to the inner face of themantle (25) of the cylinder (10), roll or equivalent part with athin mantle, to positions determined on the basis of measurements, in order tocompensate for the errors in the circumferential deflectionline of the mantle (25) such that, when the cylinder (10), roll or equivalentpart revolves, the circumferential deflection line is compensatedand dynamic unbalance is eliminated.
