Wind turbine gearbox casting manufacturing requirements and comparison with welded parts

- Dec 05, 2018-

Wind power gearbox casting, which is a casting and is a component of a wind turbine gearbox. Therefore, based on this, it is necessary to have a certain understanding and understanding of this type of casting to know how to use it correctly and reasonably, so as to have a good use effect, instead of causing product waste or adverse effects.


1. Wind turbine gearbox castings, is it required to be manufactured? What are the key considerations when purchasing products?

Wind power gearbox castings are manufactured with high requirements, and are mainly ferritic ductile iron castings. In terms of specific requirements, good tensile strength, elongation and stiffness are required, and good performance is required at low temperatures. Moreover, with the development of large-scale wind power generation equipment, the requirements for such castings are getting higher and higher, and the thickness requirements will reach 300 mm or more, and the shape requirements will become more and more complicated, and it is a large casting.


Wind power gear box casting products purchase considerations, product origin, detailed parameters, real-time quotes and price quotes, product quality, manufacturer and product after-sales service these six factors must be considered, can not be ignored and omitted, otherwise, Will affect the correct choice of the product.


2. Wind turbine gearbox castings, is the size large or small? How to choose the right size?

Wind turbine gearbox castings are available in large and small sizes, but in general, such castings are large castings, and small sizes are rare. Moreover, in wind power plants, large-scale wind power gearbox castings are also required. As for the size selection, it is mainly determined by the actual situation and the use requirements.


3. Comparison of wind turbine gearbox castings and wind turbine gearbox weldments

Wind power gearbox castings and wind turbine gearbox weldments, all of which are wind turbine gearboxes, differ in the production process, the former for casting and the latter for welding. Considering the two aspects of strength and processing technology, the wind turbine gearbox weldment is superior to the wind turbine gearbox casting. In terms of use, wind turbine gearbox castings are suitable for mass production, and wind turbine gearbox weldments are suitable for single and small batch production. Therefore, it is summarized that the two types of wind turbine gearboxes are very different and cannot be mistakenly selected and
