| Performance characteristics: in the operation process of wind turbine, wind wheel force condition is extremely bad, in the rapidly changing? Continuous operation under heavy load, the various loads have through the spindle directly to the gearbox, thus bearing gearbox load increase bad. According to the different application positions, the bearing of the speed increasing box has different working conditions for the bearings from the low speed shaft to the high speed shaft, but the bearing reliability is not less than 99%, and the service life is more than 20 years. |
