Product Description

Main shaft for MW-class wind turbine

Tongyu has now become one of worlds largest production bases of MW-Grade wind turbine shaft,

Which is a core part in wind turbine to connect wind mill and gearbox or engine ,Wind turbine main shaft are manufactured from steel ingot with forging,heat treatment ,and finishing processes,


Since the cost of replacing shafts is rather high,so the quality requirement in producing them must be high.

The service life of Tongyu main shaft is generally to be at least 20 years, Main shaft for MW-class wind turbine processes large dimension. It calls for high requirement in performance ,flaw detection,and metallographic structure.


Tong yu provides main shaft of wind turbine for various corporations,like GE Energy, Vestas, GAMESA, Suzlon,

Anderson ,Sinovel, Guodian union, CSIC wind power, Nanjing NGC group,etc.


Clients are required to offer their drawings and technical requirement, Which will transferred to technical department(heat treatment center, large forgings research center, mechanical research center, and welding department, etc,) for confirmaion and accounting, Then we will offer you the quotation, The ordered products will be put into production as soon as possible after clients have placed an order.  For any problems rasied in the product line ,We will contact and disscuss with our clients directly.


Technical Parameters

 Materials 42CrMo, 34CrNiMo6, etc..
 Common main shaft models 1.25MW 1.5MW, 2MW, 2.1MW, 2.3MW, 2.5MW, 2.85MW, 3MW, 3.3MW, 4MW, 5MW, etc..




Manufacturing Process


Smelting-Forging-Heat treatment-Roughing-Quenching and Tempering-Machining-Coating-Packaging.


Quality control.
  1. In the smelting process, to ensure high purity and low gas content of raw materials, apart from the required chemical elements, we have strict contolr upon some harmful elements such as P S Pb Sn As Sb and Bi, as well as some gas or nonmetallic debris like H N and O.
  2. Strict forging technique is employed both to ensure there are no flows inner the products ,and to keep main shafts microstruture consistent with the overall shape of forgings, The comprehensive processing lines commit that the spare parts are of good mechanical properties and long service life.
  3. Product will acquire high comprehensive mechanical properties after quenching and high-tempreture tempering treatment . The impact performance is high whether for 42CrMo main shaft of room temperature, or low-temperature 34CrNiMo6 shaft.
  4. We employ CNC equipment for finishing to ensure the high processing accuracy of our forgings , The advanced painting and coating technique for corrosion resistance will meet the requirement of long-term filed work.
