Method of correcting unbalance of a rotating body.

摘要

In a method of correcting the unbalance of a rotating body (R), data relating to initial unbalanced amounts or weights (U1, U6) at two predetermined correcting planes axially spaced and passing through the body is processed to determine correcting positions (2 to 5) and corrective machining weights (u2 to u5). The correcting positions and corrective machining weights are used for calculating the location of each center of gravity of each corrective machining portion and residual unbalanced amounts (U7, U8) in the axial direction on the assumption that corrective machining has been effected. The value of each of the residual unbalanced amounts will be compared with a predetermined value corresponding to its tolerance. If the value exceeds the tolerance, new initial unbalanced amounts or new correcting planes are assumed so that the new data will be converted into new initial information (U1 min , U6 min , U sec (Z1 min ), U sec (Z6 min )) to be fed back to the original step (16) of processing the initial unbalanced amounts. By repeating the operating processes (16 to 23) the residual unbalanced amounts will be within the tolerance so that accurate corrective machining can be effected, balancing the rotating body with a one-time machining.
