PITCH ASSEMBLY FOR A WIND TURBINE ROTOR BLADE |
| 摘要 |
The present disclosure is directed to a pitch assembly for coupling a rotor blade to a hub of a wind turbine. In one embodiment, the pitch assembly includes a first pitch bearing having a first outer race and a first inner race rotatable relative to the first outer race via a first set of rolling elements, a second pitch bearing having a second outer race and a second inner race rotatable relative to the second outer race via a second set of rolling elements, and at least one spacer configured axially between and contacting the first and second pitch bearings. Further, at least a portion of the first pitch bearing and at least a portion of the second pitch bearing are axially aligned between the rotatable hub and the rotor blade in a generally span-wise direction. |
