Wind power planet carrier castings process requirements and its planetary frame structure

- Oct 22, 2018-

Wind power planet carrier castingss, which can be understood to be obtained by casting this part of the wind power gearbox, are therefore castings. Moreover, this kind of casting should have a deep understanding and comprehensive understanding, in order to know what it is and how to use it correctly and reasonably, and then have good performance and use effect in the use of the product.


1. Wind power planet carrier castingss, should we avoid casting defects during the casting process?

Wind power planet carrier castingss, which are a specific type of casting, and there are many different kinds of products, and can be produced by different production processes, but in general, casting is used, but only in casting types. It will be different. Therefore, in the casting process, the product is to avoid casting defects, and at the same time, if casting defects occur, it should be analyzed and corresponding improvement measures should be proposed to improve the product qualification rate.


2. Planetary frame for megawatt wind turbine gearbox. Is it a wind turbine gearbox casting? What are its components?

The planetary carrier for the megawatt wind turbine gearbox is a wind turbine gearbox casting, and it can be studied in the casting process. Through the numerical simulation of the speed field and temperature field of the planetary frame casting process, the planetary carrier is improved and optimized. The casting process and reduce the generation of casting defects. In addition, heat treatment experiments can be used to determine the normalizing process of the planet carrier to improve the mechanical properties of the planet carrier, thereby reducing the production cost.


The planetary frame for the megawatt wind turbine gearbox in the Wind power planet carrier castings is composed of a main body, a connecting arm, an end cover and the like in terms of structural composition. The main body is formed by an upper flange and a main shaft substantially perpendicular to the upper flange, and the end cover is a lower flange. In addition, the upper flange and the end cap are connected to the connecting arm by means of an assembly space. In the overall structure, it adopts split connection, which has the advantages of simple structure, easy processing and safe and reliable use.


3. Technical development and specific requirements for wind turbine gearbox castings

The wind power gear box casting includes a hub, a base, an axle, and a casing, a torsion arm, a planetary gear bracket, and the like which constitute the gear box, and these are representative. In order to meet the requirement of continuous and trouble-free use for not less than 20 years, the casting is required to have very good product quality, 100% of the parts are subjected to non-destructive testing, and the requirements of the European standard EN-12680 are 2-3. All of its castings can be made of ductile iron in the material, but different grades of ductile iron are used in different parts.
