    Inspection and repair on HANGZOU ADVANCE GEARBOX GWC6066 gearbox

    Scope of work:

    - Inspection Propulsion GBX, Hangzhou Advance GWC 6066

    Micro pitting has been found on the following flanks:

    - Intermediate shaft AHEAD gearwheel working flank (1st stage).
    - Intermediate shaft AHEAD drum gear working flank (2nd stage).

    The micro pitting is most likely formed in the last 2.5 months, the micro pitting could be initiated by small hard metal particles in the lubrication oil.

    Micro pitting and in line pitting has been observed on the following flanks:
    - Intermediate shaft AHEAD pinion working flank (3rd stage).
    - Output shaft gearwheel working flank. AHEAD

    - Inpection Propulsion gearbox, Hangzhou Advance GWC 6066

    Micro pitting is found on the working flank of the pinion gear of the intermediate shaft AHEAD and working flank of the Bull gear of the output shaft.

    Micro pitting is a phenomenon that can be found on (hardened) gears. Multiple factors can affect the development of micro pitting, most important factors are surface roughness, lubrication or an incorrect gear mesh. The damage shows itself by a matted grey colour of the teeth. This as outcome of surface fatigue. The development of the micro pitting can be stabilized or progressive. A progressive development can eventual

    At the request of our customers from Denmark, we have a repair job done on board in the port of Rotterdam. There were already complaints, so for sure one of the bores should be re-machined. Before we had to dismantle the complete gearbox and the upper casing transported to our workshop. In-house we have the machining done. Obviously we performed a further inspection. The entire repair has occurred under approval of Bureau Veritas.
