AI Technical Summary
In existing wind turbine pitch reducers, the axial fixation of the low-speed stage planetary components is insufficient, leading to displacement and axial movement, which affects transmission accuracy and stability, and may cause component collisions and wear, thus shortening service life.
The combination of a limiting baffle and a snap ring is used to limit the axial displacement of the low-speed planetary components, ensuring that they are fixed within a reasonable range and preventing axial movement.
It effectively prevents displacement and axial movement of low-speed planetary components, improves transmission accuracy and stability, extends the service life of the reducer, and reduces manufacturing costs and maintenance difficulty.
