Abstract
The utility model relates to a waterwheel generator rotor structure which comprises a mainshaft 1, a wheel hub 2, a wheel arm 3, a magnetic yoke 4, a magnetic pole 5 and a fan 6. The utility model is characterized in that an iron core of the magnetic pole 5 is in a monobloc forging turriform structure, the magnetic pole 5 is provided with a heat radiation winding, and the fan 6 is a screw paddle fan in an axial flow type. The rotor iron core of the utility model adopts the monobloc forging turriform structure, the magnetic pole is provided with the heat radiation winding, and the fan is the screw paddle fan in an axial flow type having a strong axial blasting action; therefore, the stress force requirement to the material when the rotor turns and flies in a high speed can be satisfied, and a sufficient heat radiation area and a reasonable ventilation path for the ventilation and the heat radiation of the magnetic pole are provided. The utility model has the advantages of simple structure, easy processing, etc.
Description
Technical field
The utility model relates to generator amature, particularly relates to a kind of hydraulic generator rotor structure.
Background technology
The influence of determining mainly to consider two aspect factors of rotor structure, the one, the mechanical stress of rotatable parts when flying to escape must satisfy the allowable value of material, and the 2nd, the ventilation of magnetic pole and heat radiation require to have enough area of dissipations and rational ventilating path.
Summary of the invention
The purpose of this utility model just is to overcome the deficiencies in the prior art, a kind of hydraulic generator rotor structure is provided, to the mechanical stress requirement of material, improve result of ventilating heat dissipation when flying to escape, can be used as the high-speed high capacity hydroelectric generating set rotor to satisfy rotor high-speed.
Goal of the invention of the present utility model is achieved through the following technical solutions: a kind of hydraulic generator rotor structure, comprise main shaft, wheel hub, wheel arm, yoke, magnetic pole, fan, wheel hub is the connector between main shaft and the wheel arm, the wheel arm is yoke fixedly, magnetic pole is fixed on the yoke, pole core is the monobloc forging pyramidal structure, magnetic pole band heat radiation circle.
Because the linear velocity of rotor rotor cylindrical when flying to escape reaches 160 meter per seconds, tail tension stress, the shear stress of magnetic pole are very high, the stress value of yoke portion critical section is also very high, pole core of the present utility model for this reason adopts the solid forging mode, in the time of not only can satisfying rotor high-speed and fly to escape to the mechanical stress requirement of material, and think ratio with monobloc forging broach solid magnetic pole structure, can reduce manufacture difficulty and shorten the process-cycle.
Long-pending in order effectively to increase the interpolar ventilation section, it is stressed to improve coil, and pole core adopts pyramidal structure, can save the auxiliary obstruction that loses ventilating such as interpolar bracer or magnetic pole shroud like this, improve the radiating effect of magnetic pole, the heat that magnetic pole is produced can in time be taken away.Pole coil has adopted the structure of band heat radiation circle, further strengthens the heat-sinking capability of magnetic pole.
Adopt the strong axial-flow type of axial blasting action to revolve the oar fan, can strengthen the entad heat radiation of portion of iron mandrel, make generator shaft reduce to minimum as far as possible to the temperature difference of each one.
From top narration as can be seen, rotor core described in the utility model has adopted the monobloc forging pyramidal structure, magnetic pole band heat radiation circle, fan adopts the strong axial-flow type of axial blasting action to revolve the oar fan, not only can satisfy the stress requirement of rotating when flying to escape at a high speed to material, and for the ventilation and heat of magnetic pole provides enough area of dissipations and rational ventilating path, and have simple in structure, be easy to advantage such as processing.
Description of drawings
Fig. 1 is the utility model rotor structure profile.
Fig. 2 is the utility model fan scheme of installation.
Embodiment
Further describe the technical solution of the utility model below in conjunction with accompanying drawing: as Fig. 1, Fig. 2, a kind of hydraulic generator rotor structure, comprise main shaft 1, wheel hub 2, wheel arm 3, yoke 4, magnetic pole 5, fan 6, wheel hub 2 is the connectors between main shaft 1 and the wheel arm 3, wheel arm 3 is yoke 4 fixedly, magnetic pole 5 is fixed on the yoke 5, and magnetic pole 5 iron cores are the monobloc forging pyramidal structure, magnetic pole 5 band heat radiation circles.
The contrast of pyramidal structure pole core and conventional field structure heat dispersion, the distance of conventional field structure two neighboring pole coil bottom is 10 millimeter, behind the employing turriform magnetic pole, then can be extended to 90 millimeter, ventilating path has obtained tangible improvement.
Rotor fan adopts the strong axial-flow type of axial blasting action to revolve the oar fan, can strengthen the entad heat radiation of portion of iron mandrel, makes generator shaft reduce to minimum to the temperature difference of each one as far as possible.
