Abstract

A method for manufacturing a propeller reduction gear, which includes measuring manufacturing defects of the casing; calculating a first angular play induced at each intermediate gear by the measured manufacturing defects; estimating a second angular play induced at each intermediate gear by deformations of the casing when the reduction gear transmits a threshold torque; calculating a total angular play from the first angular play and the second angular play; and selecting two intermediate gears with a phase difference that compensates for the total angular play.
