Description
Technical field
This utility model relates to vertical hydropower generator, is specifically related to a kind of have inside and outside centrosome, low pass windage loss
Consumption and air quantity and blast adjustable novel rotor supporting structure.
Background technology
Rotor field spider is the critical component of hydrogenerator rotating part moment of torsion transmission, is to couple yoke, generator shaft
Intermediate member.Under static state, hot keystroke stress to be born up；When electromotor is properly functioning, rotor field spider electricity to be born
The gravitational moment of magnetic moment of torsion, magnetic pole and yoke, the centrifugal force self rotating generation and remaining keystroke power.On the other hand, rotor props up
Frame has fan effect, and the blast head of the generating set overwhelming majority is all produced by rotor field spider, is air quantity, blast, wind speed
Critical component with draft loss regulation.Along with generator capacity is continuously increased, technology continuous progressive, to the requirement of efficiency also
More and more higher.And draft loss accounting in electromotor total losses is relatively big, improving one of important means of generator efficiency is exactly
Reduce draft loss.
Vertical type high-capacity hydrogenerator meets requirement for the mechanical strength ensureing its rotor field spider, often uses tradition
Oblique support arm structure.As depicted in figs. 1 and 2, this structure includes: centrosome lower flange 20, skew web plate 30, outer ring plate 40, ring flat-plate
50, straight web 60, big stud 70, middle ring flat-plate 80, centrosome cylinder 90, gusset 100 and centrosome upper flange 110, wherein: in
Heart body lower flange 20, centrosome cylinder 90, gusset 100 and centrosome upper flange 110 assembly welding form a centrosome；Outer ring plate
40, middle ring flat-plate 80 one end is welded with skew web plate 30, and the other end welds with straight web 60；Outer ring plate 40, middle ring flat-plate 80, straight abdomen
Plate 60 welds with big stud 70；Skew web plate 30 welds the whole rotor field spider of formation with centrosome cylinder 90.
This structure utilizes the flexibility of its skew web plate 30 that its stress is converted into radial force and tangential force, reduces overall structure
Stress.Applying on this structure the most many Large-scale machine set, the power station such as Ru Ertan, Three Gorges, small stream Luo Du all have employed tradition
Oblique support arm structure.But the oblique support arm structure fresh air inlet position of traditional form is to be determined by the external diameter of centrosome.Ventilating path

The inner ring plate that keeps out the wind carries out welding with interior centrosome lower flange face and interior centrosome upper flange surface；Arrange outside centrosome cylinder outside tiltedly
Web and straight web；Straight web is welded with outer ring plate and middle ring flat-plate, outer ring plate and middle ring flat-plate and stretches out the portion of straight web
Divide and be welded on skew web plate；Outer ring plate, straight web and middle ring flat-plate are all welded on big stud.
Compared with prior art, the utility model has the advantages that:
1. the adjusting range of this structure vent locations and size increases, and vent locations and size can be according to actual measurement wind
Amount blast, it is achieved convenient and adjust accurately；
2. the flexibility of rotor field spider will not be damaged by the adjustment of vent locations and size, the stress to rotor field spider
Impact is not resulted in yet.
3. this rotor field spider structure can effectively shorten hydro-generator ventilation path, reduces entrance blast, reduces electromotor and leads to
Windage loss consumes, and improves generator efficiency.
4. this structure air vent may be adjusted to seal the position of lid away from thrust bearing oil groove, it is to avoid square on oil groove
Become negative pressure, reduce formation and the diffusion probability of mist of oil.
