SYSTEM FOR ADJUSTING TORSIONAL FREQUENCY OF A POWER TRAIN

摘要

A load coupling device for a power train including: a rotatable shaft; a first flange on a first end of the shaft, wherein the first flange is adapted to couple to a first rotating shaft of at a torque producing turbine or a torque driven electrical generator; a second flange on an opposite end of the shaft, wherein the shaft is adapted to couple to a second rotating shaft of the other of the turbine and the generator, and an annular ring extending radially outward from the first flange, wherein the mass of the annular ring is selected to shift a torsional natural frequency of the power train away from an operational condition of the power train. Trim masses may be added to make fine adjustments to the torsional natural frequency of the power train.

1. A power train comprising:
a torque producing power source including a rotating connecting flange; a torque driven power load including a rotating connecting flange; a load coupling having a first flange adapted to couple to the connecting flange of one of the torque producing power source and the torque driven power load; a second flange on load coupling adapted to couple to the coupling flange of the other of the torque producing power source or the torque driven power load, and an additional mass attachable to at least one of the connecting flanges or the load coupling wherein the additional mass is configured to shift a torsional natural frequency of the power train away from an operational condition of the power train and the additional mass is symmetrically distributed about a longitudinal axis of the power train.
