Abstract

Una cadena de tracción para una turbina eólica de eje horizontal (1), que comprende: un árbol principal (5) provisto con un reborde de unión del rotor (5C) adaptado para conectarse con un rotor (4) de la turbina eólica, y un alojamiento de cojinete principal (51) que tiene un cuerpo principal (514) que rodea al menos parcialmente el árbol principal y se extiende desde un primer extremo (5141) hasta un segundo extremo (5142), siendo una distancia desde el segundo extremo al reborde de unión del rotor más grande que una distancia desde el primer extremo al reborde de unión del rotor, presentando el cuerpo principal en el segundo extremo un reborde de unión de componente (513) para una conexión del alojamiento a un componente adicional de la cadena de tracción, soportando el alojamiento de cojinete principal (51) el árbol principal mediante un primer cojinete (52) y un segundo cojinete (53), siendo una distancia entre el segundo cojinete y el reborde de unión del rotor más grande que una distancia entre el primer cojinete y el reborde de unión del rotor, teniendo el alojamiento de cojinete principal (51) un primer asiento (511) para el primer cojinete, y un segundo asiento (512) para el segundo cojinete, comprendiendo el alojamiento de cojinete principal (51) un reborde del asiento (515) que se extiende desde el cuerpo principal al menos parcialmente hacia dentro de modo radial, situándose el segundo asiento en un extremo distal del reborde del asiento, caracterizado porque el reborde del asiento está conformado como un cono truncado, en el que el extremo distal es el extremo más estrecho del cono truncado, en el que la distancia desde el extremo distal al reborde de unión del rotor es más grande que la distancia desde el extremo más ancho del cono truncado al reborde de unión del rotor.
