The instability of the use environment，wind power bearing

Rotor shaft bearings , supporting the blade and rotor,  transmitted the rotating torque to the growth machine. Because the wind often change, the load and torque acting on the spindle bearing have great changes.

  Below the starting wind speed (for minimum wind speed power required) , the main shaft of the rotor is in idle state, at low speed and light load operation, but when above the starting wind speed, the rated revolution power state, rise, also reached the average load. Especially when the wind power bearing suddenly blows , through the blade, rotor, spindle bearing can bear great load.
