Abstract
A manufacturing method of a gear box for a rotating machine for transmitting power of a motor, the gear box including a bull gear connected to an input shaft of the motor and a pinion gear meshing with the bull gear, forms the bull gear and the pinion gear based on a design result determined using a designing method of a gear box. In the designing method of a gear box, pitch circle diameters of the bull gear and the pinion gear are determined such that a rotation speed of the pinion gear is the same and a center-to-center distance of a bull gear and the pinion gear is the same regardless of a frequency of AC power supplied to the motor.
