The Yaw Gear is a crucial component in a wind turbine. In some cases, the teeth may be damaged due to wear and tear after years in operation.
CNC Onsite has developed a unique patented concept to make Up Tower repair on Yaw Ring.
We have developed a CNC controlled milling machine that removes the damaged teeth. In the milled pocket a new tooth segment is mounted, and the turbine can quickly be back in operation.
The milling process is performed with a fully controlled CNC machine. This ensure high precision as in a workshop. After the milling the pocket are measured with special control measurement tools to ensure a perfect fit.
This new solution gives the possibility to replace either sections or all teeth in a Yaw Gear. With this patented system the lifetime of the Wind Turbine can be extended.
