Automatic lubrication device for wind turbine pitch and yaw gears


Product Concept:

Microlubgear is a new concept for lubrication systems that takes advantage of the volume in gear dedendum to embed a micro-fabricated part that continuously supplies fresh grease at the contact region. The system takes advantage of micro-technology and micro-tribology to fabricate a micro-nozzle that is the base of a new generation of high efficiency automatic lubrication systems.

Customer Needs:

Reduce energy generation losses due to losses of efficiency and downtimes due to failures involving corrective or preventive maintenance of wind turbine pitch and yaw gears.

Main Milestones:

  • Product validated in test bench: Sep 2014
  • Product validated in wind turbine: Dec 2014

Unique Selling Proposition:

  • Direct workspace lubrication
  • No energy production losses
  • Low cost
  • Possible integration into any wind turbine
