Fasteners for the wind energy sector: aero generators and wind turbines

A wind farm is a group of structures designed to generate electricity using wind power. These structures are called aero generators—the most common being wind turbines—and they are built using products that meet the highest quality standards in order to maximise their useful life and optimise performance.

At CHAVESBAO, we offer a wide selection of standardised fasteners specifically intended for manufacturing aero generator components and other products for the wind energy sector.

Standardised fasteners for aero generators and wind turbines

The use of standardised bolts helps to guarantee the quality and safety of components used in the wind energy sector. In our catalogue, you will find a range of fasteners whose design and composition comply with various DIN standards:

  • Hexagon head bolts: Hexagon head bolts for the manufacture of aero generators are produced according to standards DIN 931 and DIN 933. DIN 931 bolts have a hexagonal head and a cylindrical body with a half thread. DIN 931 bolts are available in grades 8.8 and 10.9. DIN 933 hexagon head bolts also have a hexagonal head but, unlike DIN 931 bolts, the body is completely threaded.
  • Hexagon nuts: Hexagon nuts for the manufacture of aero generators and wind turbines are produced according to DIN 934. This is the most common type of nut on the market and, in our catalogue, you will find a wide range of grade 8 and grade 10 products—with different strength ratings—depending on the type of component to be manufactured.
  • Flat washers: Our flat washers are produced according to standards DIN 125 and DIN 9021. DIN 125 flat washers are used in a wide range of applications. DIN 9021 washers, on the other hand, are wider, providing a greater surface area for load distribution.

En CHAVESBAO disponemos de una amplia selección de tornillería estandarizada para la fabricación de componentes de aerogeneradores o cualquier otro elemento del sector eólico.

Tornillería estandarizada para aerogeneradores y turbinas eólicas

El uso de tornillos estandarizados garantiza la calidad y seguridad de los productos empleados en la fabricación de los componentes dentro del sector eólico. En nuestro catálogo encontrarás una gama de tornillería que se ajusta a las diferentes Normas DIN que hacen referencia a la composición y estructura de cada uno de los productos:

Tornillos hexagonales

Los tornillos hexagonales aptos para la fabricación de aerogeneradores están fabricados según las Normas DIN 931 y DIN 933 que aplican a su estructura. En el primer caso se componen de cabeza hexagonal y cuerpo cilíndrico con media rosca. Además, los tornillos DIN 931 están disponibles en calidad 8.8 y 10.9. Los tornillos hexagonales DIN 933 incluyen también cabeza hexagonal, pero, a diferencia de los primeros, en estos el cuerpo está totalmente roscado.

Tuercas hexagonales

Las tuercas hexagonales para la fabricación de aerogeneradores y turbinas eólicas se ajustan a la Norma DIN 934 que hace referencia a la composición y estructura de las mismas. Este tipo de tuercas son las más comunes en el mercado y en nuestro catálogo podrás encontrar una amplia selección de productos en calidad 8 y calidad 10 -con diferentes grados de resistencia- que se adaptan según el tipo de componente a fabricar.

Arandelas planas

Las arandelas planas se ajustan a las Normas DIN 125 y DIN 9021. Las arandelas planas DIN 125 se utilizan comúnmente en una amplia variedad de aplicaciones. Sin embargo, las arandelas DIN 9021 son más anchas que las anteriores proporcionando una mayor superficie para la distribución de la carga.
