Our forging Factory is a leading manufacturer specialized in the production of high-quality wind turbine gear blanks. Wind turbine gearbox gear blanks are highly specialized parts that must meet stringent performance requirements.Wind turbine gearbox gear blanks are highly specialized parts that must meet stringent performance requirements.

The MW-class wind turbine main shaft is a key component of wind power generation systems. It plays a vital role in transferring the rotational energy of the turbine hub to the generator, and ultimately converts the wind’s kinetic energy into electricity. Our main shafts are designed to withstand the most challenging wind conditions, providing maximum reliability and efficiency.

A turbine blade is a radial aerofoil mounted in the rim of a turbine disc and which produces a tangential force which rotates a turbine rotor. Each turbine disc has many blades. As such they are used in gas turbine engines and steam turbines. The blades are responsible for extracting energy from the high temperature, high pressure gas produced by the combustor. The turbine blades are often the limiting component of gas turbines.To survive in this difficult environment, turbine blades often use exotic materials like superalloys and many different methods of cooling that can be categorized as internal and external cooling,and thermal barrier coatings. Blade fatigue is a major source of failure in steam turbines and gas turbines. Fatigue is caused by the stress induced by vibration and resonance within the operating range of machinery. To protect blades from these high dynamic stresses, friction dampers are used.

A steam turbine consists of a rotor resting on bearings and enclosed in a cylindrical casing. The rotor is turned by steam impinging against attached vanes or blades on which it exerts a force in the tangential direction. Thus a steam turbine could be viewed as a complex series of windmill-like arrangements, all assembled on the same shaft. Because of its ability to develop tremendous power within a comparatively small space, the steam turbine has superseded all other prime movers, except hydraulic turbines, for generating large amounts of electricity and for providing propulsive power for large, high-speed ships。 The rotor shaft is a central component of the electric motor. The rotor shaft is the carrier shaft for the laminated core of the rotor and thus transmits the electrically induced torque via a corresponding positive connection in the transmission.The turbine shaft connects the turbine to the generator, turning at the same speed as the turbine. It is essentially an item that is used in machine designed for producing continuous power. The system it is used in basically extracts energy from a fluid flow and then converts it into a usable form or medium.Rotor shafts are also used in many large and traditional sectors of engineering, such as power generation and mining. They are key components in many power generation plants and are often of huge size and power.The main material grades for tubine rotor shafts we produced before are :
