Abstract

The utility model discloses a wind generating set is with the driftage bearing, and it is including driftage bearing inner race, ring gear, the ring gear is the components of a whole that can function independently with driftage bearing inner race, and the ring gear is in the same place with the top of the tower flange is fixed with the inner circle of driftage bearing respectively. The utility model discloses because the ring gear adopts split type structure with the driftage bearing, has reduced the maintenance degree of difficulty, has lowered the replacement cost. Especially, when ring gear partial failure, it can only to need to be changed counterpart ring gear segmental arc. The utility model discloses still relate to an aerogenerator who contains this kind of driftage bearing.

Description

A kind of wind-driven generator unit yaw and wind-driven generator
Technical field
This utility model relates to wind-driven generator field, particularly relates to a kind of wind-driven generator unit yaw and wind-driven generator.
Background technology
In wind-driven generator field, the outer ring of yaw is fixed together with bottom, cabin, the inner ring of yaw is fixed together with tower top flange, belong to important support, drive mechanism, generally yaw uses inner ring and ring gear monolithic construction, when losing efficacy occurs in the part tooth of ring gear, and can only integral replacing yaw, maintenance difficulty is big, and replacement cost is high.
Utility model content
The deficiency existed for prior art, the purpose of this utility model is to provide a kind of wind-driven generator unit yaw that can change gear ring and wind-driven generator.
The technical scheme that this utility model provides is: a kind of wind power generating set yaw, it includes yaw inner ring, ring gear, described ring gear and yaw inner ring are splits, and ring gear inner ring and tower top flange with yaw respectively is fixed together.
For the ease of installation and removal, described ring gear bottom is provided with ring gear adpting flange, ring gear adpting flange is fixed together with ring gear, described yaw inner ring bottom is provided with the cushion cap matched with ring gear adpting flange, and yaw inner ring, ring gear adpting flange, tower top flange are bolted on together.
Described ring gear includes that two or more ring gear segmental arc, adjacent ring gear segmental arc are positioned by positioner.
Preferably, the quantity of described ring gear segmental arc is 4 to 8.
Preferably, the quantity of described ring gear segmental arc is 6.
This utility model also includes a kind of wind-driven generator, and it includes that yaw, described yaw are yaw described above.
Advantageous Effects of the present utility model is, owing to ring gear uses split-type structural with yaw, reduces maintenance difficulty, reduces replacement cost.Particularly, when ring gear partial failure, it is only necessary to change corresponding part gear ring segmental arc.
Accompanying drawing explanation
Fig. 1 is this utility model yaw assembly generalized section;
Fig. 2 is the annular gear structure schematic diagram of this utility model yaw.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Referring to the drawings, a kind of wind-driven generator unit yaw, it includes yaw inner ring 3, ring gear 4, described ring gear 4 is split with yaw inner ring 3, ring gear 4 is fixed together with yaw inner ring 3 and tower top flange 5 respectively, described ring gear 4 bottom is provided with ring gear adpting flange, ring gear adpting flange is fixed together with ring gear 4, described yaw inner ring 3 bottom is provided with the cushion cap matched with ring gear adpting flange, and yaw inner ring 3, ring gear adpting flange, tower top flange 5 are bolted on together.
During work, yaw outer ring 2 is connected with cabin 1, and during driftage, yaw inner ring 3, ring gear 4 and tower top flange 5 keep static, and yaw outer ring 2 realizes rotating.
This utility model further relates to a kind of wind-driven generator, and it includes that yaw, described yaw are yaw described above.
It is more than a kind of embodiment of the present utility model, a preferred demonstration example.The scope that this utility model application is claimed is not only limited in described embodiment.All and the present embodiment equivalence technical scheme belongs to protection domain of the present utility model.
