Abstract
Novel electricity generator rotor shaft flow fan, comprise wheel hub and be circumferentially located at several paddle flabellums of hub outside surface, described wheel hub and paddle flabellum are structure as a whole, wheel hub and paddle flabellum adopt high strength wrought aluminium to process, the leading flank of paddle flabellum is plane, the trailing flank of paddle flabellum is cambered surface, and the cross section at paddle flabellum top is identical with the cross section of root, and the angle between paddle flabellum and hub centre line is 58-70 °.The utility model is owing to adopting aluminum high-strength material, and whole fan weight can greatly reduce on the one hand, and fan becomes multiple to reduce by the centrifugal force caused of conducting oneself with dignity, and adopt high strength wrought aluminium material on the other hand, the centrifugal force that himself can bear is also larger.
Description
Technical field
The utility model belongs to technical field of generators, is specifically related to a kind of novel electricity generator rotor shaft flow fan.
Background technique
Fan of generator rotor is as the essential elements of cooled electric generator inner air, its fan work efficiency directly affects the normal operation of generator, in addition due to generator amature High Rotation Speed, fan self will bear the huge centrifugal force of conducting oneself with dignity and bringing, therefore fan own wt can not be too high, and self also will have higher mechanical strength.
Model utility content
The utility model, in order to solve deficiency of the prior art, provides the novel electricity generator rotor shaft flow fan that a kind of structure is simple, lightweight, efficiency is high, easy for installation.
For solving the problems of the technologies described above, the utility model adopts following technological scheme: novel electricity generator rotor shaft flow fan, comprise wheel hub and be circumferentially located at several paddle flabellums of hub outside surface, described wheel hub and paddle flabellum are structure as a whole, wheel hub and paddle flabellum adopt high strength wrought aluminium to process, the leading flank of paddle flabellum is plane, the trailing flank of paddle flabellum is cambered surface, the cross section at paddle flabellum top is identical with the cross section of root, and the angle between paddle flabellum and hub centre line is 58-70 °.
Described wheel hub front-end face and ear end face are respectively equipped with the compensating groove of a ring, compensating groove are arranged with two mount inlets for installing equilibrium block in compensating groove.
Adopt technique scheme, the utility model has following beneficial effect:
Owing to adopting aluminum high-strength material, whole fan weight can greatly reduce on the one hand, and fan becomes multiple to reduce by the centrifugal force caused of conducting oneself with dignity, and adopt high strength wrought aluminium material on the other hand, the centrifugal force that himself can bear is also larger.
Angle between paddle flabellum and hub centre line is 58-70 °, can reduce windage like this, fully improves the working efficiency of fan.
The setting of compensating groove and two mount inlets, is easy to manufacture, and is convenient to install, improves fan stability in the course of the work.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is perspective view of the present utility model;
Fig. 3 is the plan view of Fig. 1.
Embodiment
As shown in Figure 1, Figure 2 and Figure 3, novel electricity generator rotor shaft flow fan of the present utility model, comprise wheel hub 1 and be circumferentially located at several paddle flabellums 2 of wheel hub 1 outer surface, described wheel hub 1 and paddle flabellum 2 are structure as a whole, wheel hub 1 and paddle flabellum 2 adopt high strength wrought aluminium to process, the leading flank of paddle flabellum 2 is plane, the trailing flank of paddle flabellum 2 is cambered surface, the cross section at paddle flabellum 2 top is identical with the cross section of root, and the included angle A between paddle flabellum 2 and wheel hub 1 center line is 58-70 °.
Wheel hub 1 front-end face and ear end face are respectively equipped with the compensating groove 3 of a ring, compensating groove 3 are arranged with two mount inlets 4 for installing equilibrium block in compensating groove 3.
The utility model has following beneficial effect:
Owing to adopting aluminum high-strength material, whole fan weight can greatly reduce on the one hand, and fan becomes multiple to reduce by the centrifugal force caused of conducting oneself with dignity, and adopt high strength wrought aluminium material on the other hand, the centrifugal force that himself can bear is also larger.
Included angle A between paddle flabellum 2 and wheel hub 1 center line is 58-70 °, can reduce windage like this, fully improves the working efficiency of fan.
