| 摘要 |
The invention relates to a method for manufacturing a propeller reduction gear, which comprises the following steps: measuring manufacturing defects of the casing (∆Yav, ∆Zav, ∆Yar, ∆Zar); calculating a first angular play (δfabrication) induced at each intermediate gear (2a, 2b) by the measured manufacturing defects (∆Yav, ∆Zav, ∆Yar, ∆Zar); estimating a second angular play (δdéformation) induced at each intermediate gear (2a, 2b) by deformations of the casing (12) when the reduction gear transmits a threshold torque; calculating a total angular play (δtotal) from the first angular play and the second angular play; and selecting two intermediate gears with a phase difference (-δtotal) that compensates for said total angular play. |
