EXAMPLES


The three examples shown above are planet wheel bearing inner races from a kW class, a 1.5MW and 2MW gearboxes.


The problem manifests itself in the same way irrespective of the turbine/gearbox size. The root cause of the problem was identified by Moventas over a decade ago and is a lecture in itself. However the solution that is proven to work is to use a planet wheel with the bearing outer race form ground into the planet wheel.


This is generally referred to as an integrated planet wheel bearing. Moventas has been using this in serial production on all gears at 850kW and above and has pioneered the upgrade to existing gear designs to integrated planet wheel bearing during workshop service.


NON-STOP DEVELOPMENT The previous examples are just a few of the many changes made to wind turbine gearboxes over the last thirty years. The development never stops and at Moventas we strive for ever increasing quality and with that quality ever increasing reliability.


In a world where wind is one of the only energy generation forms where the cost of generation is reducing, we aim to make a difference. By being better we can reduce the cost of generation further.
