Hub for a horizontal axis wind turbine |
摘要 |
To provide a lightweight hub of a horizontal axis wind turbine with a balanced strength, the hub 1 related to the present invention comprises a reinforcement plate 4 coupled to the spherical shell 2 on the peripheral edge in the round region G inside the circular flange 3 used to secure a blade. In addition to being off-center at the point C side, an off-center opening 5, that contains the center B of the region G, is formed in the region G. The reinforcement plate 4 is formed at the remainder portion of the region G after removing the off-center opening 5. By means of an unequal arrangement of the reinforcement plate 4 and the opening 5 on the inside of the circular flange 3, severe imbalances due to the casting of the hub 1 are cancelled and a balanced strength is obtained, making it also easier to reduce the weight. |
