Strengthening Friction Grip Joints in Wind Turbines.

A wind turbine manufacture wanted higher static friction in order to improve the friction grip joints in their solutions. The desire for higher static friction was fulfilled using friction shims from Sintex.

The process is simple and has only a few steps. Heated metal powder is sprayed onto the component at extremely high speed. The speed at which the powder is sprayed and the flame temperature are both very high, although the surface temperature of the component being sprayed never exceeds 100 degrees. This prevents thermal distortions in the underlying material, which is one of the disadvantages of other processes. The tungsten carbide coating process thereby has good adherence, but also ensures extreme hardness, good wearing properties and high static friction.

The process is optimized for medium and large series, which makes Sintex and this technology partner a good match.

How has our technology partner benefitted from collaboration?

• Strengthened solution
• More wear-resistant solution
• Extended lifetime in the joint

… and of course higher static friction as required.
