Introduction to load-distributing planetary gearboxes for wind turbines.
Optimized drive solutions increase efficiency and lifespan of wind turbines. ATEK Drive Solutions explains how load-distributing planetary gearboxes improve system performance and reduce maintenance costs.
The key role of planetary gearboxes
Planetary gearboxes are crucial for modern wind turbines, especially in the multi-megawatt range. Their ability to transmit high torques in a small space and distribute loads, makes them the standard for systems over 3 MW. More information on planetary gearboxes is available. ATEK analyzes turbine-specific requirements.
Challenges in the wind energy sector
Wind turbine gearboxes are exposed to extreme conditions such as irregular load peaks caused by gusty winds, which can overwhelm conventional gearboxes. Load-distributing planetary gearboxes for wind turbines are designed, to distribute these stresses across multiple gears, which can increase lifespan by over 15% compared to standard designs. ATEK offers robust solutions for renewable energy..
ATEK’s approach to optimization
Through experience and simulation technology, ATEK ensures the optimal adaptation of each gearbox. Modular building systems and custom adaptations allow for gearbox solutions precisely tailored to load profiles and operating conditions that can increase efficiency by up to 2%. Information on planetary drives with motors is available.Functionality and benefits of load-distributing planetary gearboxes in wind turbines
The structure: Compact and powerful
A sun gear surrounded by three to five planet gears in a ring gear handles turbine forces. This arrangement, characteristic of a load-distributing planetary gearbox for wind turbines, allows for single-stage ratios of up to 1:120. The compact design reduces space and weight in the gondola, lowering overall system costs. For specific requirements, angular planetary gearboxes are available.
- Compact design with sun gear, planet gears, and ring gear for high power density.
- Enables high single-stage ratios, for example up to 1:120.
- Significantly reduces space requirement and weight in the gondola, contributing to overall cost reductions.
- The load is distributed across multiple planet gears, significantly reducing point loads.
- Can extend the lifespan of the gearbox by thousands of operating hours.
- Achieves high efficiencies of over 98% per stage.
- Minimizes friction losses and noise emissions, often below 70 dB(A) at the gearbox.
Load distribution as the elixir of life
Uneven load distribution causes overexertion and premature wear. The ability to distribute loads is a core feature that makes load-distributing planetary gearboxes for wind turbines so valuable. Distributing the load over multiple planet gears significantly reduces point loads and can extend the life of the gearbox by thousands of operating hours. ATEK develops load-distributing planetary gearboxes.
