Complete inspection of a 55 MW load gearbox

Stork Gears & Services was hired for the complete inspection of a 55 MW load gearbox. During this inspection a full visual inspection of the pinion, gear wheel and white metal bearings has been carried out. Also bearing clearances (with inside micrometers), backlashes (main gear set and pump drive) and axial float of the high speed shaft have been checked.
The load gearbox is part of a gas turbine driven generator set. Our engineers - with power market specific expertise - were able to multi-task in a high demanding environment, from supervision and projectmanagement to executing of onsite-maintenance and complete inspections. We completed the whole project within the fixed timeline of two weeks.
