| Abstract:Aiming at the gear tooth breakage of a gas motor in a marine high-speed diesel generator set during the start-up, comprehensive investigation was carried out on the aspects of gas motor design, components quality and assembly process. The results showed that wrong installation method led to abnormal meshing gap of the gas motor, which finally resulted in gear tooth breakage. The assembly process was modified and verified, and the fault has never occurred again. |
| Key words: diesel engine gas motor gear tooth breakage assembly |
