Part belongs to rotational parts, and therefore, it will not only have the due mechanical performance of general rotatable parts, it is necessary to have good electricity
Magnetic property.Magnetic pole is mainly made of components such as pole core, pole coil, Damper Windings.The magnetic pole of hydrogenerator can root
Different patterns is made into according to the height of the size of its capacity, revolving speed, such as solid magnetic pole, the solid magnetic pole of laminated pole-shoe and full wafer
Formula laminted pole etc..Stacked pole core is mainly made of parts such as pole lamination, pressing plate, screw rod (pull rod) or rivets.It is folded
Chip pole core is a kind of most common structure of magnet pole of rotor of hydraulic generator, is adopted on the generator of different capabilities
With.Stacked pole core is built up with iron-core lamination, and the generator of open slot is used to stator, it is contemplated that reduces magnetic pole surfaces
Tooth pulsation loss, select stacked magnetic pole advantageously.Pole core, which fastens routine, has rivet to fasten and stretching screw fastening
Structure.Its core length of small generator is short, and iron-core lamination area is small, is generally fastened using rivet.Most of hydrogenerators
Pole core all uses stretching screw and pressing plate fastens pole core, and pole core requires screw rod and specialized nut not when fastening
Clamp surface must be protruded, the necessary joint welding of specialized nut is on stretching screw.
Utility model content
The utility model mainly solves the deficiencies in the prior art, provides a kind of compact-sized degree height, saves water
A kind of fastening of magnet pole of rotor of hydraulic generator iron core of the processing of turbine generator pole end-plate and stretching screw and specialized nut
Structure.
Above technical problems of the utility model are mainly solved by the following technical scheme:
A kind of fastening structure of magnet pole of rotor of hydraulic generator iron core, including iron core, the outer of the iron core are cased with uniformly
Continuously distributed magnetic pole book punching, the punching of outermost layer magnetic pole book are cased with the magnetic pole thickness punching of uniformly continuous distribution, outermost layer magnetic outside
The upper end of extremely thick punching is equipped with the pole shoe sleeve to socket-connect with magnetic pole thickness punching, and the lower end of the outermost layer magnetic pole thickness punching is set
There is the sleeve to socket-connect with magnetic pole thickness punching, the outer end of the pole shoe sleeve is equipped with damping ring, is equipped in the damping ring
Amortisseur bar, the amortisseur bar extend through the punching of magnetic pole thickness and magnetic pole book punching；
Between the pole shoe sleeve, the punching of magnetic pole thickness and magnetic pole book punching, between sleeve, the punching of magnetic pole thickness and magnetic pole book punching
Pass through internal screw thread screw rod locking respectively.
Preferably, the top of the damping ring, the top of magnetic pole thickness punching, magnetic pole book punching top be in same water
Plane distribution, the outer wall of the pole shoe sleeve lower end, the outer wall of sleeve are in same level EDS maps, the magnetic pole thickness punching
Overall thickness be greater than the thickness of pole shoe sleeve, the overall thickness of the magnetic pole thickness punching is greater than the thickness of sleeve.
Preferably, between the internal screw thread screw rod and pole shoe sleeve, between internal screw thread screw rod and sleeve, damping ring and pole shoe
It is fixed respectively by screw between sleeve.
With sleeve, internal screw thread screw-fastening pole core.Sleeve is packed at pole core both ends and replaces pole end-plate, with band
Internal thread screw rod replaces former stretching screw.The advantages of such structure, is omitted pole end-plate, does not need specialized nut, section
Machining period is saved.In addition, sleeve can be made into standard parts and components, can greatly raise labour productivity.Therefore, with sleeve, interior
Thread screw fastening structure had not only reduced the manufacturing cost of motor, but also shortened the duration, had the clear superiority of application.
The utility model provides a kind of fastening structure of magnet pole of rotor of hydraulic generator iron core, compact-sized, further mentions
Lift operations performance.
