Abstract
The utility model relates to a driving device for type testing of a wind generating set. The driving device for the type testing of the wind generating set is composed of variable frequency motors, a torque sensor, a gear box and a universal coupling. The variable frequency motors are connected with the torque sensor. The torque sensor is connected with a high-speed shaft of the gear box. A low-speed shaft of the gear box is connected with a driving shaft of the universal coupling. A driven shaft of the universal coupling is used to be connected with a hub of a tested wind generating set. The angular speed of the driving shaft of the universal coupling is equal to that of the driven shaft of the universal coupling. When the tested wind generating set is arranged and fixed, the tested wind generating set does not need carefully adjusting and centering, and auxiliary time for installing the wind generating set before testing is shortened. At the same time, an axis of the tested wind generating set can be not in the same line with an axis of the gear box. The tested wind generating set can be arranged on a platform according to primitive states so that lifting and assembling are more convenient to operate.
