Abstract
Abstract A method and apparatus for balancing a rotor in at least one plane. The geometrical parameters of the rotor are stored along with test values representing the rotor in balance as determined during a test run. These stored values are transmitted to a frame computer which determines the size and phase relationship of counterweights necessary to balance the rotor. The test values resulting from the test run are stored for the entire duration of the balancing operation upstream of the frame computer. Also, the geometrical parameters of the rotor may be recalled and displayed at any time during the operation.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
81 words
A method of balancing an imbalanced rotor in at least one plane, said method comprising the steps of: storing the geometrical parameter value of said rotor; measuring, during a test run, test values representative of imbalances; storing said test values; transmitting, in accordance with a program sequence control means, said geometrical parameter value and said test values to a frame computer; and determining the size and phase relationship of counterweights to balance the rotor, utilizing said stored parameter and test values.
Claim 2
Independent Claim
81 words
A method of balancing an imbalanced rotor in at least one plane, said method comprising the steps of: storing the geometrical parameter value of said rotor; measuring, during a test run, test values representative of imbalances; storing said test values; transmitting, in accordance with a program sequence control means, said geometrical parameter value and said test values to a frame computer; and determining the size and phase relationship of counterweights to balance the rotor, utilizing said stored parameter and test values.
Claim 3
Dependent Claim
28 words
A method according to claim 1, wherein the test values resulting from said measuring step are stored for the entire duration of balancing upstream of said frame computer.
Claim 4
Dependent Claim
