Description
Technical field
This utility model is related to a kind of rotor of steam turbo generator and encourages end fan seat ring and structure with flange.
Background technology
In modern power systems, widely used Turbo-generator Set single-machine capacity is increasing, and shafting model is complicated, turns round
Shake and the danger of subsynchronous resonance generation also increases, if using the exciter from simultaneously excitation generator, steady from transient state generator rotor angle
Considering, it is feasible that large turbo-type generator promotes the use of self excitation system to provisioning request.As properly increased excitation forcing ratio, from simultaneously
The advantage of encouraging becomes apparent from, and does not interfere with the action message of main protection it is also ensured that back-up protection correct operation, excises fault.
Not only there is no rotary part, operational reliability is high, easy to maintenance, and because rotary inertia reduces with respect to brushless exciter.
Rotor of steam turbo generator transmits the load torque of steam-turbine fed, but moment of torsion passes to electromotor when encouraging end, steam turbine generator
Diminish in the dynamic torque of the torsional vibration of shafting encouraging side, the shear stress encouraging end axle diminishes, therefore encourage end axle safe clearance
Greatly.Simultaneously because adopt whole roots rotor, also to manufacture bring cost increase and precision it is difficult to ensure that the problems such as.
Content of the invention
This utility model provides a kind of rotor of steam turbo generator to encourage end fan seat ring and structure with flange, reduces difficult processing
Degree, improves the accuracy of manufacture, and the rotor of steam turbo generator reducing manufacturing cost encourages end fan seat ring and structure with flange.This
Utility model technical scheme is：A kind of rotor of steam turbo generator encourage end fan seat ring and structure with flange by cooling fan (1),
Shaft coupling flange (2), boss type fan seat ring (3), body shaft (4), encourage end axle (5), bolt (6), nut (7) composition, wherein exist
Boss type fan seat ring (3) position encouraging end of rotor of steam turbo generator is divided into body shaft (4) and encourages (5) two sections of the axle in end, body
Axle (4) is upper to carry shaft coupling flange (2), encourages end axle (5) and above carries boss type fan seat ring (3), cooling fan (1) is installed and is placed on
On fan seat ring (3), shaft coupling flange (2) and fan seat ring (3) by the way of bolt (6) and nut (7) apply pretightning force
Couple together.
Body shaft (4) and shaft coupling flange (2) solid forging structure, body shaft (4) and shaft coupling flange (2) adopt high intensity to close
Golden steel making.
Encouraging end axle (5) adopts conventional material forging integral with fan seat ring (3).
Operation principle
This utility model according to stress distribution, using the knockdown rotor of steam turbo generator new construction of different materials.
Because rotor of steam turbo generator transmits the load torque of steam-turbine fed, but moment of torsion passes to electromotor when encouraging end, and steamer is sent out
Motor diminishes in the dynamic torque of the torsional vibration of shafting encouraging side, and the shear stress encouraging end axle diminishes, and therefore encourages answering of end axle
Power safe clearance is big, encourages end axle and can adopt conventional material, reduces manufacturing cost.Meanwhile, body shaft is due to by steam turbine
The moment of torsion effect of supply, body shaft adopts high strength alloy steel, so that each section of shaft part material is rationally applied.Reduce each simultaneously
The length of section axle, thus reducing difficulty of processing, improves the accuracy of manufacture.
Technique effect
1st, this utility model, in the boss type fan base ring position encouraging end of rotor of steam turbo generator, is divided into body shaft and encourages
Two sections of the axle in end, processes shaft coupling flange in body shaft, processes boss type fan seat ring on encouraging end axle, and cooling fan is installed and placed
On fan seat ring, then shaft coupling flange and fan seat ring are coupled together by applying pretightning force mode with bolt.Turbine generator
Machine diminishes in the dynamic torque of the torsional vibration of shafting encouraging side, and the shear stress encouraging end axle diminishes, and therefore encourages the stress of end axle
Safe clearance is big, encourages end axle and can adopt conventional material, reduces manufacturing cost.
2nd, this utility model processes shaft coupling flange in body shaft, processes boss type fan seat ring, wherein on encouraging end axle
Be machined with bolt hole on shaft coupling flange and boss type fan seat ring, then with bolt by apply pretightning force mode shaft coupling flange and
Fan seat ring couples together, and reduces the length of each section of axle, thus reducing difficulty of processing, improves the accuracy of manufacture.
Brief description
Fig. 1 rotor of steam turbo generator encourages end flanges Standard profile.
Specific embodiment
As shown in figure 1, a kind of rotor of steam turbo generator encourages end fan seat ring and structure with flange, by cooling fan 1, connection
Shaft flange 2, boss type fan seat ring 3, body shaft 4, encourage end axle 5, bolt 6, nut 7 form, wherein in rotor of steam turbo generator
Boss type fan seat ring 3 position encouraging end be divided into body shaft 4 and encourage 5 two sections of the axle in end, body shaft 4 carries shaft coupling flange 2, encourages
Boss type fan seat ring 3 is carried, cooling fan 1 is installed and is placed on fan seat ring 3, applies using bolt 6 and nut 7 on the axle 5 of end
Plus the mode of pretightning force is coupled together shaft coupling flange 2 with fan seat ring 3.
Body shaft 4 and shaft coupling flange 2 solid forging structure, body shaft 4 adopts high-strength alloy steel with shaft coupling flange 2
Make.
Encouraging end axle 5 adopts conventional material forging integral with fan seat ring 3.
Steam turbine generator diminishes in the dynamic torque of the torsional vibration of shafting encouraging side, and the shear stress encouraging end axle diminishes,
The stress safe clearance therefore encouraging end axle is big, encourages end axle and can adopt conventional material, reduces manufacturing cost.
This utility model processes shaft coupling flange in body shaft, processes boss type fan seat ring, wherein join on encouraging end axle
It is machined with bolt hole on shaft flange and boss type fan seat ring, then with bolt by applying pretightning force mode shaft coupling flange and wind
