The second stage sun shaft is a critical transmission component in the wind turbine gearbox drivetrain, responsible for transferring torque from the gearbox or rotor to the generator.
As a professional
wind turbine gearbox shaft manufacturer, we produce
high-precision sun Shaft Forgings that represent the forefront of
wind power drivetrain manufacturing. Each shaft is made from
premium alloy Steel Forgings and undergoes
CNC machining and Heat Treatment in-house to ensure exceptional strength, dimensional accuracy, and long service life.
