Technical Field
The utility model belongs to the technical field of aerogenerator, specifically be an auxiliary structure who strengthens driftage drive output support rigidity.
Background
The yaw action of the wind generating set is realized by the yaw driving torque provided by the yaw driving motor, the speed is reduced through the yaw gearbox, and the action of a small gear at the output end of the yaw gearbox on the large yaw gear ring. A common support solution for the yaw drive output is cantilever support. Under the supporting effect of the cantilever, the deflection of the yaw driving output end is large, and the meshing of the yaw output pinion and the large gear ring has an unbalance loading phenomenon, so that the stress condition of the gear teeth becomes severe. Problems with such cantilever structures have been recognized and improvements have been proposed.
Publication No. CN103994033A proposes to mount the yaw drive on a support fixed to the base, which provides support for both sides of the yaw drive output pinion, forming a simple support.
Publication No. CN109340058A proposes that the support seat of the yaw drive output end adopts a symmetrical double-layer structure scheme, so that the yaw drive output end forms a simply supported support.
Publication No. CN206439372U proposes an improvement for a yaw gearbox, where a yaw gearbox casing envelopes a yaw gearbox output pinion, providing support to both ends of the output pinion, reducing the cantilever effect at the output end of the yaw pinion.
Publication No. CN205638788U proposes a solution in which supports are provided on both sides of the yaw gearbox output pinion in the tooth width direction, so that the stressed type of the output pinion is a simple beam.
The disclosed solution simply provides support on both sides of the yaw output pinion in the tooth width direction to form a simple support structure. However, for how to reasonably design the supporting structure, the load condition of the yaw driving output end can be effectively improved, and the unbalance load in the meshing of the yaw driving output pinion and the large gear ring is further reduced, no disclosed scheme exists at present.
Disclosure of Invention
