Background technology
For high-rating generator, rotor dynamic balancing is very crucial, at present, usually takes the fan in generator axle stretch end
Install balance weight on impeller additional, non-shaft stretching end, that is, exciter end opens balance in the main pole rotor line coil close to exciter rotor
Groove, realizes that dynamic balancing is adjusted, due to main pole by installing balance weight additional on compensating groove and welding balance weight in compensating groove
The outside diameter of rotor line coil is smaller, and the compensating groove opened is relatively also smaller, and because of close main pole coil, so the welding of balance weight is stranded
Difficulty, particularly, this structure is since bobbin cannot be replaced, to the balance adjustment of unit when can not realize field adjustable.
The content of the invention
It is an object of the invention to overcome disadvantages described above, there is provided one kind is rational in infrastructure and can realize Site for Unit dynamic balancing tune
A kind of generator rotor structure and generator of section
The technical scheme is that：A kind of generator rotor structure, it includes balancing frame, and the balancing frame sets generator to encourage
Between magnetomechanical rotor and non-shaft stretching end bearing and it is fixed on alternator shaft, the balancing frame is equipped with compensating groove, described flat
The opening of weighing apparatus groove is towards non-shaft stretching end bearing, and compensating groove is equipped with the entrance for placing balance weight, according to dynamically balanced needs, compensating groove
The position inside to match is fixed with balance weight.
Preferably, convenient for the ease of Field adjustment, the outside diameter of the balancing frame is cylindrical more than generator amature.
Preferably, in order to reduce weight, the balancing frame is equipped with lightening hole.
Preferably, the section of the groove is the big trapezoidal shape in the small the inside in outside.
Preferably, in order to ensure that the amount of unbalance of rotor body is small as far as possible, the compensating groove is recessed for circumferencial direction
Groove.
Preferably, the quantity of the groove is two.
Preferably, in order to mitigate the weight of balancing frame, it is different with more than two diameters that the balancing frame includes chassis
Donut, the different donut of described two diameters above is fixed on the non-shaft stretching end bearing side on chassis, two neighboring
Compensating groove is formed between donut.
The invention further relates to a kind of generator, it includes generator rotor structure, and the generator rotor structure is above-mentioned
The generator rotor structure.
The method have the benefit that stretching outside by the non-axis of generator since balancing frame is installed on, do not influence to generate electricity
The maintainability and operability of machine；By the size and weight of adjustment groove inner equilibrium block, Site Detection simultaneously adjusts generator turn
Sub- dynamic balancing, reduces the unbalance residual content of generator, reduces Generator Vibration noise, improves unit vibration and noise reducing
Performance.
