Abstract

A method for hardening a surface of a component in a wind turbine is disclosed. The component to be hardened includes a surface and the surface is applied with a blasting material by ultrasound waves. The component is a part of a drive or a drive housing, a bearing surface, a gear wheel or a pinion. The ultrasound waves are emitted with the aid of a piezo electric transducer.

Claims

exact text as granted — not AI-modified
1 .- 9 . (canceled) 
     
     
         10 . A method for hardening a surface of a component in a wind turbine, comprising:
 applying a blasting material by ultrasound waves with the surface of the component.   
     
     
         11 . The method as claimed in  claim 10 , wherein the component is a part of a drive or a drive housing, a bearing surface, a gear wheel or a pinion. 
     
     
         12 . The method as claimed in  claim 10 , wherein the ultrasound waves are emitted by a piezo electric transducer. 
     
     
         13 . The method as claimed in  claim 10 , wherein the ultrasound waves are emitted in a frequency between 10 kHz and 30 kHz. 
     
     
         14 . The method as claimed in  claim 10 , wherein the ultrasound waves are amplified. 
     
     
         15 . The method as claimed in  claim 10 , wherein the blasting material comprises a tungsten carbide. 
     
     
         16 . The method as claimed in  claim 10 , wherein the blasting material comprises a ball. 
     
     
         17 . The method as claimed in  claim 10 , wherein the ball has a diameter of more than 1 mm. 
     
     
         18 . The method as claimed in  claim 17 , wherein the ball has a diameter of more than 5 mm.
