Problems solved by technology
[0004]At present, the main way to maintain the motor air gap is to increase the rigidity of the entire generator system, such as increasing the stiffness of the stator or rotor. The application of these methods means As the weight of the generator increases, the cost of manufacturing and transportation rises sharply

The invention relates to a generator and a wind generating set. The generator comprises a mounting shaft, a power generation unit and a connecting assembly. The power generation unit is arranged on the mounting shaft, the power generation unit comprises an inner component and an outer component which are coaxially arranged, one of the inner component and the outer component is a rotor, the other one is a stator, and the outer component is connected to the mounting shaft. The connecting assembly is arranged between the mounting shaft and the inner component, so that the connecting assembly is rotationally connected with the mounting shaft. The connecting assembly comprises an axial connecting piece arranged in an axial gap and a radial connecting piece arranged in a radial gap, and at leastone of the axial connecting piece and the radial connecting piece is of a bearing bush structure. According to the generator and the wind generating set provided by the embodiment of the invention, the power generation requirement of the wind generating set can be met, meanwhile the bearing capacity is better, the stability of a motor air gap can be ensured, and the power generation benefit of the wind generating set is further ensured.
Description
technical field [0001] The invention relates to the technical field of wind power, in particular to a generator and a wind power generating set. Background technique [0002] A wind turbine is a device for converting wind energy into electrical energy. The main component used for energy conversion is a generator. The generator usually includes a rotor and a stator. The rotor and the stator are arranged opposite to each other with a motor air gap between them. When the generator is applied to a wind power generating set, its rotor can be connected to the hub of the impeller through a rotating shaft, and the stator can be connected to the base of the nacelle through a fixed shaft. Its working principle is that the impeller drives the rotor to rotate under the action of wind load, so that the rotor and the stator move to cut the magnetic force line, thereby generating magnetic induction current and generating electricity. [0003] Due to the rigid connection between the hub an...
