Description
Technical field
The utility model belongs to technical field of wind power generation, and in particular to a kind of bearing block of wind power generating set.
Background technology
The impeller of wind power generating set is generally connected to gear-box by main shaft, and main shaft is by main shaft supporting in wind-power electricity generation
On owner's supporting structure, conventional main shaft is spheric roller bearing, and each bearing uses a bearing block, and its bearing block structure is such as
Shown in CN203730577.
There is end-play in spheric roller bearing, main shaft axial jump, influence the normal use of gear-box.Wind-driven generator
Manufacturers are proposed some solutions, CN103518062 and CN204419878 and made using two single-row tapered roller bearings
For main shaft, in order to ensure the axiality of bearing saddle bore, the bearing block of two bearings is designed to one, and uses lower margin at 4
Mode be arranged on base on.
The bearing block of lower margin formula at above-mentioned this 4, in structure design and base is discontinuous, causes to need in junction
Many materials are wanted just to can guarantee that connection is reliable, the totle drilling cost of bearing block and base is higher.
CN101173652 proposes to employ inclined method with the continuous bearing block scheme of base, bearing block in a kind of structure
Orchid is connected with base, and the gross weight of such bearing block and base is reduced.But the shortcomings that this bearing block, is, inclined connection
Face can increase machining cost, and inclined plane bolt is not a whole circle, and the conductive performance of power is bad.
CN104989601 proposes that and bearing block employs and main shaft with the continuous bearing block scheme of base in a kind of structure
The vertical flange of axial line is connected with base, is effectively reduced the gross weight of bearing block and base, and program bearing block does not include
Impeller locking device.
Utility model content
The defects of the utility model is in order to make up prior art, there is provided one kind overcome integral bearing seat weight lay particular stress on,
There is no the bearing block of the wind power generating set of the shortcomings of impeller stop pin seat, bearing block high expensive on bearing block.
The utility model is achieved by the following technical solution：
A kind of bearing block of wind power generating set, the main body of the bearing block is revolving body, and bearing block outer surface is at least
One ring flange, bearing block both ends inside are provided with the shoulder hole of installation main shaft, and the revolution section of the bearing block main body is in substantially
Chevron shaped, bearing block leading exterior surface protrudes at least one impeller stop pin seat.
Further, the ring flange is arranged on chevron shaped top.
Further, the section of the attachment structure of the locking key seat and bearing block is in C fonts substantially；C fonts section is from lock
Rationed marketing seat to bearing block changes from small to big.
Further, there is conical oil baffle on the inside of the shoulder hole.
Further, the oil baffle keeps certain gap with main shaft, the fluted, thread groove on the face of cylinder of main shaft
Deng auxiliary sealing structure.
The beneficial effects of the utility model are：A kind of bearing block structure of wind power generating set of the utility model is simply, again
Amount is light, be readily transported, cost is low, and impeller stop pin seat can be with less material, and good power conductive performance transmits impeller locking
When load, oil baffle has good casting manufacturability, can effectively block principal axis lubrication fat in itself.
