Abstract

Perfeccionamientos en ventiladores de hélice larga de dos palas para máquinas ventiladorasque comprenden: un cubo a montar sobre un árbol de accionamiento; un par de espigas espaciadas en 180º y extendidas hacia el exterior desde el cubo; una pala de ventilador extendida diametralmente hacia fuera desde cada respectiva espiga; y caracterizados por unos medios que aseguran dichas palas a las espigas para distribuir la carga de tensión en las palas sobre un área extensa y suficiente para evitar la concentración de tensión en un espacio relativamente pequeñopara aplicar una gradual carga de doblamiento a la pala adyacentemente a dichos medios y para permitir la flexión de tales medios y de las palas en una porción sustancial del área mencionada.
