Let’s discuss how our project managers, engineers, and skilled team can help you with your equipment repair and engineering needs.

Western Machine Works has the skilled technicians, project management, custom tooling, and engineering expertise to handle all aspects of wind turbine main shaft refurbishing and repair. Our windpower repair services include:

National OilSeal

Restore the wind turbine’s main bearing fits and worn-out surfaces to factory specifications or better with the two arc thermal spray coating/metalizing process. The two wire arc process uses a 420 stainless steel material with a bond strength in excess of 6000 psi to provide a superior bearing fit surface that is more resilient to fretting and corrosion.

Custom tooling and fixtures are designed to efficiently and correctly assemble main shaft components. Critical dimensions of all main shaft components are documented during the disassembly and inspection process.

SKF oilseal

Western Machine Works services all major wind turbine brands and is well-equipped to repair the world’s most popular wind turbine models including the Siemens 2.3MW, V82, and GE 1.5MW.

To improve reliability and ensure efficient operation of your main shaft assembly, our engineering team evaluates dimensional data and failure analysis results to determine design upgrades. We also have the in-house capability to reverse engineer and manufacture new components.

Wind power usage is projected to grow 10% over the period from 2020 to 2025. Renewable energy still competes with energy sources like fossil fuels, solar, and hydro for energy production. Keeping costs low is crucial for wind turbine efficacy and wind power adoption. Regular wind turbine maintenance helps keep costs down energy production up.Rotating components, like shafts and bearings, are where most of the wear and tear occurs. Tolerances can increase over time from regular wear and corrosive compounds in the air (especially if the wind turbines are near a coastline). As the tolerances on the shaft and bearing become greater, the bearing fit loosens. This can also be accelerated by vibrations that increase as tolerances grow. In extreme cases, bearing failure can occur, which may necessitate shaft and bearing replacement, which halts energy production and increases cost to the wind farm.By regularly scheduling maintenance on aging components, resurfacing the shafts to OEM specs, and balancing the shafts, efficiency is increased, and downtime is limited to scheduled windows of time.
