Our repairs go far beyond the simple replacement of damaged parts, incorporating design and/or manufacturing improvements that extend the useful life of the original design.


The Component Services Program provides you an inventory option that minimizes maintenance costs on windmills downtime.


Why reengineering?

The gearbox is a critical element in any wind power train, especially in those with high operational demands, and is therefore directly related to an important part of the operation and maintenance costs of any wind farm.

Failure events involving a major corrective - either repair or complete replacement of the gearbox - usually arise and grow significantly from the first third of the theoretical operating period, i.e. 30% of the design life certified by independent official bodies.

In our experience at Gamesa Gearbox, this dramatic reduction in expected life can be directly related to (1) design and/or manufacturing errors, and/or (2) inappropriate operation and/or maintenance strategies.

The first of the reasons, design and/or manufacturing errors, may be a priori surprising since gearbox design and manufacturing concepts have been known and mastered for decades, and their validity is more than proven in all types of industrial applications. However, this direct transfer of industrial standards is precisely the mistake in approach that all manufacturers have made when approaching the first designs for the wind environment.

In recent years, new designs have evolved significantly in terms of the robustness and reliability they offer when operating under wind turbine operating conditions, which differ from the quasi-static conditions of most industrial applications.

Specific areas of improvement

The bearings industry has evolved considerably in recent years both at the design level and in the area of manufacturing technologies, in order to offer tailored solutions for the wind power sector. Despite these improvements, however, the remaining key challenge is to select the right bearing to deliver the degree of reliability required for each position within the gearbox.

Gear failure is not common, except in isolated cases of grinder burn. However, contact pressure distribution over the teeth is key to good overall gearbox dynamics, in terms both of the distribution of forces and bearing vibration performance.

In recent years, the leading manufacturers have significantly improved their capacity for gear micro geometry definition, manufacturing, measurement and testing. Specific software, ample and appropriate production, manufacturing and inspection resources, and test-beds with load testing capacity have made it possible to obtain the precision data required to produce new designs.

The impact of lubrication on the longevity of a gearbox, in any sector, should never be underestimated. A very common error in early design trials, however, was the failure to ensure an exact reproduction of the whole wind turbine lubrication system, and this resulted in non-optimized and even faulty performance.

We consider this a key issue and our test beds therefore reproduce the exact lubrication conditions of the wind turbine gearbox.

Our differential value

We are committed to extending the service life of damaged units for a period longer than the time elapsed before the first failure.
