Description
Technical field
Technical field of hydraulic generators is the utility model is related to, more particularly, to a kind of hydraulic turbine generator magnet yoke.
Background technology
Rotor rim is the part of hydrogenerator magnetic circuit, and the structure member of fixed magnetic pole.Generator flies
Wheel torque is mainly produced by yoke.The structure of rotor rim is typically according to generator capacity, rotating speed, manufacturing process and installation etc.
What factor determined.Generally, the rotor rim of small-capacity generator be linked to be by way of hot jacket with main shaft one it is whole
Body.
Traditional upper magnet yoke uses cast steel material, and because casting quality is unstable, percent defective is of a relatively high.Such as CN202435160U
A kind of disclosed high rotating speed water turbine generator yoke " dove tail " slot structure.The structure of traditional slow-speed of revolution yoke is polygonized structure,
The deficiency that polygon cast steel yoke processing capacity is big, and the production cycle is grown be present.
Utility model content
The defects of in order to overcome prior art, the utility model provide a kind of high yield rate, hydraulic generator easy to process
Machine yoke.
In order to solve the above-mentioned technical problem, the utility model provides a kind of hydraulic turbine generator magnet yoke, including circular yoke piece；
The wind-guiding band being connected with the circular yoke piece；The dovetail slot being arranged on the circular yoke piece；It is connected with the dovetail slot
Magnetic pole；Between the circular yoke piece and magnetic pole, the cushion block that is connected with the circular yoke piece.
As further improved technology scheme, hydraulic turbine generator magnet yoke provided by the utility model, each magnetic pole and circle
At least provided with two pieces of cushion blocks between shape yoke piece；Each cushion block is located at two sides of dovetail slot respectively.
It is uniform as further improved technology scheme, hydraulic turbine generator magnet yoke provided by the utility model, the dovetail slot
It is distributed in the circular yoke piece radially；The cushion block is in " Contraband " shape, and the height of landing leg at both ends is different, the cushion block and circle
After the connection of shape yoke piece, the top surface of the cushion block of a certain dovetail slot both sides, half with the circular yoke piece by the dovetail slot center
Footpath is vertical.
In the case where not conflicting, above improvement project can be implemented alone or in combination.
Technical scheme provided by the utility model, circular yoke piece middle part are provided with axis hole, and circular yoke piece hot jacket is in main shaft
On.Circular yoke piece steel plate processing and fabricating, solve in prior art yoke piece production process because steel-casting quality is unstable,
The problem of percent defective is of a relatively high；Yoke piece is designed to processing when circular configuration considerably reduces making compared with polygonized structure
Amount.Wind-guiding band and cushion block are connected on circular yoke piece.There is clever structure, easy to assembly low with cost.
Brief description of the drawings
Accompanying drawing is used for providing further understanding to of the present utility model, forms the part of the application, of the present utility model
Schematic description and description is used to explain the utility model, does not form to improper restriction of the present utility model.In accompanying drawing

Between 2, the cushion block 3 that is connected with circular yoke piece 1.
Technical scheme provided by the utility model, the middle part of circular yoke piece 1 are provided with axis hole, and the hot jacket of circular yoke piece 1 is in master
On axle.The steel plate processing and fabricating of circular yoke piece 1, solves in the prior art that yoke piece steel-casting quality is unstable, percent defective
The problem of of a relatively high；Yoke piece is designed to processing capacity when circular configuration considerably reduces making compared with polygonized structure.Lead
Wind band 5 and cushion block 3 are welded on circular yoke piece.There is clever structure, easy to assembly low with cost.
Alternatively, hydraulic turbine generator magnet yoke provided by the utility model, between each magnetic pole 2 and circular yoke piece 1
Provided with least two pieces of cushion blocks 3；Each cushion block 3 is located at two sides of dovetail slot 4 respectively.
Alternatively, hydraulic turbine generator magnet yoke provided by the utility model, dovetail slot 4 are evenly distributed on circular yoke piece 1
Radially, i.e., the angle of circumference formed between adjacent dovetail slot 4 is equal, and dovetail slot 4 is in phase in the ring position of circular yoke piece 1
On same concentric circles；Cushion block 3 is in " Contraband " shape, and the height of landing leg at both ends is different, after cushion block 3 is connected with circular yoke piece 1, cushion block 3
The radius at the center of dovetail slot 4 that connects of the magnetic pole 2 that is contacted with by the cushion block of top surface it is vertical, that is to say, that a certain dove tail
The top surface of the cushion block 3 of the both sides of groove 4, it is vertical with the radius of the circular yoke piece 1 by the center of dovetail slot 4 so that magnetic pole 2 and pad
The contact surface of block 3 is vertical with the radius of the circular yoke piece 1 by the center of dovetail slot 4, i.e. the contact surface of magnetic pole 2 and cushion block 3,
In the tangential direction of circular yoke piece 1 so that the construction and arrangement of hydraulic turbine generator magnet yoke are more reasonable.
The utility model is not limited to above preferred embodiment, can also be limited in the utility model claims and specification
Spirit in, carry out the conversion and improvement of diversified forms, can solve same technical problem, and technique effect expected from obtaining,
