Description
Technical field
The utility model is related to suitable for requiring harsh generator, specially a kind of stable electric generation to rotor stability performance
The flywheel gear of machine rotating speed.
Background technology
Military generator working environment is generally relatively more severe, and external disturbance is than more serious.During generator operation, rotor is in height
The state of speed rotation, reliability index requirements MTBF MTBF >=20000h have to the spin stabilization performance of rotor
High requirement.In order to allow the more steady of rotor operation, improve to outside antijamming capability, we increase stable in rotor right-hand member
Shelves Flywheel device, flywheel gear can increase the rotary inertia of generator.The rotary inertia of generator mainly determines to send out
The mechanical corresponding speed of motor, rotary inertia are little, and fast response time is generally used for the occasion of high-speed response；And rotary inertia has greatly
Big beneficial to the anti-external interference of rotor, i.e. rotary inertia, corresponding speed is relatively slow, but is affected little by external disturbance, and rotor rotates more
Steadily.According to rotary inertia computing formula I=mr, stable disk quality increases, and rotary inertia increases therewith；But stable disk quality increases
Plus, torque also increases therewith, and the shearing force of rotating shaft also increases, according to rotating shaft,
After flywheel gear increase must be guaranteed, rotor gross mass is in the range of rotating shaft can be born.In order to meet above-mentioned requirements, and allow
Rotary inertia can adjust, and spy devises a kind of flywheel gear of stable generator rotating speed.
Content of the invention
The purpose of this utility model is to be to provide a kind of flywheel gear of stable generator rotating speed, using device itself
Architectural characteristic reaches the rotating speed of stable generator, improves anti-external disturbance ability, and the utility model intensity is good, processing and manufacturing letter
List, stable performance, installation operation convenience, structural variability are strong, and do not affect the performance of generator amature, are particularly suitable for stable
The harsh generator of performance requirement.
The utility model is achieved like this, a kind of flywheel gear of stable generator rotating speed, including Flywheel disc, balance
Block, spring washer, small washer and hexagon-headed bolt, are provided with axle pilot hole, air vent, removal hole and increase steady hole inside Flywheel disc；
Two through holes are provided with inside balance weight；It is characterized in that：Removal hole, air vent, the steady Kong Jun of increasing are around axle pilot hole center of circle array point
Cloth, and gradually spread to Flywheel disc outline；The removal hole is screwed hole, is realized to flywheel gear by removal tool special
Dismounting；Described to increase steady hole be tapped through hole, is coordinated by the screw thread pair with hexagon-headed bolt and for balance weight to be fixed on Flywheel disc
On.
Preferably, the removal hole is 4.
Preferably, the air vent is 6.
Preferably, the steady hole of the increasing is 32.
Preferably, the material that the Flywheel disc is adopted is cold-rolled steel Q235 materials, and the material that balance weight is adopted is for lead.
Preferably, the removal hole and the steady hole of increasing are internal tapping.
The beneficial effects of the utility model are：（1）Improve the stability of generator speed；（2）Lift generator anti-interference
Ability；（3）Simple to operate, practical.

Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
As shown in Figure 1, Figure 2, Figure 3, Figure 4, the utility model be such to implement, a kind of stable generator rotating speed fly
Wheel apparatus 1, including Flywheel disc 3, balance weight 7, spring washer 5, small washer 6 and hexagon-headed bolt 5, are provided with axle inside Flywheel disc 3
Pilot hole 9, air vent 8, removal hole 10 and the steady hole 11 of increasing；Two through holes are provided with inside balance weight 7；It is characterized in that：Removal hole
10th, air vent 8, increase steady hole 11 around 9 center of circle array distribution of axle pilot hole, and gradually to the diffusion of 3 outline of Flywheel disc；Described tear open
Hole 10 is unloaded for screwed hole, the dismounting to flywheel gear 1 is realized by removal tool special；It is described that to increase steady hole 11 be tapped through hole,
By balance weight 7 being fixed on Flywheel disc 3 under screw thread pair cooperation with hexagon-headed bolt 4.
The rotary inertia of generator amature needs before the utility model flywheel gear 1 is installed, must be first calculated, satisfaction is extrapolated
The quantity of the minimum balance weight 7 required for the stability of customer requirement.7 most 16 pieces of balance weight, minimum can balance
Block 7.4 balance weights 7 are adopted in Fig. 2.
When the utility model flywheel gear 1 is installed, 5 pieces of Flywheel discs 3 are sequentially loaded in rotating shaft 2, it is ensured that 5 pieces of Flywheel discs 3
Axle pilot hole 9, removal hole 10, air vent 8, increase steady hole 11 with one heart, after 3 clamping of Flywheel disc is fixed, take out 1 balance weight 7,
2 hexagon-headed bolts, 4,2 spring washers 5 and 2 small washers 6, hexagon-headed bolt 4 pass sequentially through spring washer 5, small washer 6
It is assembled together with steady hole 11 is increased on balance weight 7, with Flywheel disc 3, it is ensured that balance weight 7 is fixed on Flywheel disc 3 and does not loosen, such as
This is repeated 3 times, and installs 4 groups of balance weights 7 on Flywheel disc 3；Rotate with 2 one superhigh speed of rotating shaft when subsequent power generation machine works, there is provided
Certain rotary inertia guarantees the stability of rotor.If generator is safeguarded, when Flywheel disc 3 needs to dismantle, only need to be torn open using specialty
The bolt unloaded on instrument is connected with the removal hole 10 of flywheel gear 1, by 1 slow dismounting of flywheel gear in the presence of screw thread pair,
Avoid damaging rotating shaft 2.1 structural strength of flywheel gear is high, installs simply, easy to use.
