Specific embodiment
The utility model is described in further detail combined with specific embodiments below.
As shown in Figures 1 to 5, reinforce flange for the segmented pitch variable bearings of Wind turbines provided by the present embodiment,
It is made of first flange section 1, second flange section 2, the first cushion block 3 and the second cushion block 4, wherein the first flange section and second
Flange section is arc section, they can be spliced into a whole coil structures, while one end of the first flange section 1 sinks to having depth
The first sinking position 5 consistent with 3 thickness of the first cushion block is spent, other end sinking has depth consistent with 4 thickness of the second cushion block
The second sinking position 6, one end of the second flange section 2 sinks the third sinking for having depth consistent with 3 thickness of the first cushion block
Position 7, the other end sink the 4th sinking position 8 for having depth consistent with 4 thickness of the second cushion block, the first flange section 1 and the
After two flange sections 2 are spliced into whole circle, the first sinking position 5 and third sinking position 7 can combine and be configured to the first cushion block 3 of accommodating
Accommodating space, the second sinking position 6 and the 4th sinking position 8 can combine the accommodating space for being configured to the second cushion block 4 of accommodating, and institute
The shape size and respective cushion block for stating accommodating space match, it is described first pad, 3 and second cushion block 4 also be arc section；In addition,
Bolt hole 9, and the bolt hole 9 are provided on the first flange section 1, second flange section 2, the first cushion block 3 and the second cushion block 4
With 10 bolt hole of pitch variable bearings of Wind turbines, blade bolt hole is concentric and diameter is identical.
Reinforce the aerial installation method of flange for the above-mentioned segmented pitch variable bearings of the present embodiment below, concrete condition is as follows:
