The transmission device is connected with the supporting device, the supporting device comprises a shell and a rotor shaft, the shell is provided with a rotary groove, the outer ring of the rotor shaft is provided with a top end bearing, the rotor shaft is rotationally connected with the rotary groove through the top end bearing, one end of the rotor shaft is provided with a rotor, and the rotor is magnetically connected with a stator. According to the torque self-adjusting type anti-attrition wind driven generator rotor assembly, the supporting device serves as a main installation foundation, the flow guiding device is used for discharging air of violent airflow, the situation that the overall stability of the torque self-adjusting type anti-attrition wind driven generator rotor assembly is affected by too fast rotation caused by too high air speed is prevented, the rotation stability is detected through the adjusting device, and therefore automatic balance compensation is conducted on accumulated deformation.

Description

technical field [0001] The invention relates to the technical field of wind power generators, in particular to a torque self-adjusting antifriction wind power generator rotor assembly. Background technique [0002] In recent years, with the extensive use of resources, more and more attention has turned to clean energy. Wind power, hydropower and solar power are the three most widely used energy sources. Different power generation methods are different for different regions. Among them, the use of wind power The scope is wider. [0003] Wind generators drive the blades to rotate through high-speed airflow, so that the rotor rotates in the stator to convert wind energy into electrical energy for power generation. The rotor is supported by the rotor shaft during the rotation process. The rotor shaft and the blades are usually rigidly connected to ensure the transmission efficiency. At the initial stage of rotation, the magnetic resistance between the rotor and the stator will ...

AI Technical Summary

Problems solved by technology

The rotor is supported by the rotor shaft during the rotation process. The rotor shaft and the blades are usually rigidly connected to ensure the transmission efficiency. At the initial stage of rotation, the magnetic resistance between the rotor and the stator will make the rotor shaft unable to increase the speed in a short time, so that the rotor reaches The state of high-power power generation affects the conversion efficiency of wind power. Generally, the length of the blade is up to 100 meters and the weight is heavy. During long-term use, it is easy to cause metal fatigue and deformation. Therefore, the rotor shaft will be twisted during the rotation process, making the Stress concentration inside the rotor shaft reduces service life

[0004]In addition, wind turbines are usually installed outdoors without shelter. When the wind speed is too high, the blades rotate too fast. Once the high-speed airflow is mixed with hard objects , will cause violent impact on the blades, damage the blades, and threaten the stability of wind power conversion
