Bearing liable to damage
In wind power generation device, due to its too large equipment, maintenance inconvenience, so the device must have a long working life, usually is not less than 20 years, and today's wind power equipment failure problems in gear box is growth, and the bearing is the most easy to occur in the gear box fault components, thus reasonably choose bearing is very important for the gear box of operation, but also accurately predict its service life.
Bearing life mainly refers to the fatigue life of bearing, the bearing of the operation process, as a result of the ring and rolling body contact, make its surface after alternating load repeatedly function and form of fatigue spalling, if this fatigue spalling occurs outside the service life of bearing period is normal bearing damage, on the other hand, are not qualified.
