Industry:

Power (POWR)

 
 

Application:

Mechanical Power Transmission (MPT)

 
 

Customer Location:

Wind farm, Central Sweden

 
 

Application Date:

May 2011

 
 

Application Situation:

During maintenance of the turbine at a small wind farm, the nacelle was removed in order to inspect the internal components.

 
 

Problem:

Inspection revealed that the nacelle had suffered from water ingress and the yaw drive shaft was experiencing damage due to corrosion and wear due to lack of lubrication.

 
 

Products:

Belzona 1131 (Bearing Metal)

 

Substrate:

Steel

 
 

Application Method:

Application was carried out in accordance with Belzona System Leaflet MPT-2. A former was used to mould Belzona 1131 to correct dimensions.

 
 

Belzona Facts:

Belzona 1131 possesses self-lubricating properties for creation of low friction surfaces in the event of lubrication loss. The product is also corrosion resistant. This made it the ideal solution for the shaft repair. This application is still in service as of 2017.
