Description
Technical field
The invention belongs to rotor of steam turbo generator field, particularly relate to a kind of rotor of steam turbo generator balanced structure, the problem that when can solve rotor of steam turbo generator dynamic balance test, amount of unbalance is large.
Background technology
Rotor of steam turbo generator is when doing High Rotation Speed, due to reasons such as the error of uneven, the External Shape of material structure, rigging error, planform local are asymmetric, make not overlapped with rotation by the axes of inertia of rotor centroid, and produce centrifugal intertia force and inertia couple.Mechanical oscillation and noise can be produced when rotor rotates under the effect of centrifugal intertia force and inertia couple, accelerate bearing wear, even have a strong impact on the performance and used life of product.It is too much often to there is rotor unbalance weight in turbo generator when doing dynamic balance test in factory, reserved balance screw is filled it up with screw and still balanced to get off, and this manufactures to turbo generator and brings very adverse influence.
Summary of the invention
The object of this invention is to provide and a kind ofly solve the too much problem of rotor unbalance weight, ensure that turbo generator safe and reliable operation.
For achieving the above object, the present invention adopts following technical scheme: rotor of steam turbo generator balanced structure, comprise rotor, this rotor is rotor of steam turbo generator, the outer peripheral surface of rotor is provided with axially extended mounting groove, and mounting groove circumferentially interval is arranged, and is equipped with an axially extended rotor slot wedge in each mounting groove, on described rotor slot wedge, interval arranges several balance screw vertically, is provided with mass screw in balance screw; The groove bottom of rotor slot wedge and its place mounting groove is that interval is arranged.
The mass screw arranged in balance screw is the first mass screw or the second mass screw or the 3rd mass screw, the length of the first mass screw is 12mm-18mm, the length of the second mass screw is 20mm-25mm, and the length of the 3rd mass screw is 30mm-40mm.
All arrange in partial amt balance screw in all balance screws in the first mass screw, partial amt balance screw all to arrange in the second mass screw, partial amt mass screw and the 3rd mass screw is all set.
The weight of described rotor is 18t-30t, and described first mass screw, the second mass screw, the 3rd mass screw are M16 screw.
The weight of described rotor is less than 18t, and described first mass screw, the second mass screw, the 3rd mass screw are M12 screw.
Rotor of steam turbo generator balanced structure of the present invention, under the condition ensureing engine health and reliability, by boring multiple screw on generator amature slot wedge, according to the uneven weight of generator amature number in rotor slot wedge balance screw, increase and decrease mass screw or change the mass screw of Different Weight, because rotor slot wedge distributes at generator amature circumferencial direction, quantity is many, uneven weight adjustable extent is large, thus a difficult problem too much for uneven for generator amature weight is solved, reduce turbo generator and run the too much risk of rotor amount of unbalance, ensure that turbo generator safe and reliable operation, there is structure simple, safe and reliable, the obvious advantage of action effect.

Embodiment
By the rotor of steam turbo generator balanced structure shown in Fig. 1-Fig. 8, comprise rotor 1, this rotor 1 is rotor of steam turbo generator, the outer peripheral surface of rotor 1 is provided with axially extended mounting groove, mounting groove circumferentially arranges multiple uniformly at intervals, all plug an axially extended rotor slot wedge 5 in each mounting groove, rotor slot wedge 5 is strip.
The two sides of described rotor slot wedge 5 are provided with respectively a positioning convex 10, positioning convex 10 is axially extend, the groove bottom 12 that mounting groove comprises two trough wall surfaces 11 and is connected between two trough wall surfaces 11, each trough wall surface 11 of mounting groove is equipped with axially extended location notch, rotor slot wedge 5 inserts in corresponding mounting groove, in two location notchs on corresponding two trough wall surfaces 11 inserting mounting groove of two positioning convex 10 difference of rotor slot wedge 5, the groove bottom 12 of rotor slot wedge 5 and its place mounting groove is arranged for interval, the medial surface 9 towards rotor 1 center line side of rotor slot wedge 5 and the groove bottom 12 of this rotor slot wedge 5 place mounting groove are arranged for interval.The both ends towards the lateral surface 7 outside rotor 1 of rotor slot wedge 5 are equipped with end grooves 8, and end grooves 8 axially extends to on the end face of the rotor slot wedge 5 of this end grooves 8 homonymy.The both sides of two positioning convex 10 between the lateral surface 7 and medial surface 9 of this rotor slot wedge 5 of rotor slot wedge 5.
On described rotor slot wedge 5, interval arranges several balance screw 6 vertically, mass screw is provided with in balance screw 6, the mass screw arranged in balance screw 6 is the first mass screw 3 or the second mass screw 2 or the 3rd mass screw 4,3rd mass screw 4 is long mass screw, second mass screw 2 is moderate-length mass screw, and the first mass screw 3 is short mass screw.The length of the first mass screw 3 is 12mm-18mm, and the length of the second mass screw 2 is 20mm-25mm, and the length of the 3rd mass screw is 30mm-40mm.
The nominal diameter of all balance screws 6 (all balance screws 6 refer to all balance screws 6 on all rotor slot wedges 5) is all identical, all arrange in partial amt balance screw 6 in first mass screw 3, partial amt balance screw 6 in all balance screws 6 all arrange in the second mass screw 2, partial amt mass screw the 3rd mass screw 4, first mass screw 3, second mass screw 2 is all set, the 3rd mass screw 4 arranges some all as required.
When the weight of rotor is 18t-30t (comprising 18t and 30t), described first mass screw (3), the second mass screw (2), the 3rd mass screw (4) are M16 screw, i.e. common metric thread and nominal diameter is the screw of 16mm, now the nominal diameter of balance screw 6 also should be 16mm mutually.
When the weight of rotor is less than 18t, described first mass screw (3), the second mass screw (2), the 3rd mass screw (4) are M12 screw, i.e. common metric thread and nominal diameter is the screw of 16mm.Now the nominal diameter of balance screw 6 also should be 12mm mutually.
Rotor of steam turbo generator balanced structure of the present invention, when rotor 1 assembles, rotor slot wedge 5 is squeezed in mounting groove, when generator has assembled and has done dynamic balance test, first moderate-length mass screw (the second mass screw 2) is assemblied in all balance screws 6 on all rotor slot wedges 5, the moderate-length mass screw in rotor slot wedge 5 is changed according to the monitoring result of dynamic balance test equipment, if desired increase weight, then the moderate-length mass screw of correspondence position is replaced by long mass screw (the 3rd mass screw 4), if desired loss of weight, then the moderate-length mass screw (the second mass screw 2) of correspondence position is replaced by short mass screw (the first mass screw 3).Because rotor slot wedge 5 is many at generator amature 1 circumferencial direction distributed quantity, balance screw 6 quantity is also many, increases the adjustable range of the uneven weight of rotor 1, adds the range of choice of the uneven weight of generator amature 1.Rotor slot wedge 5 can be arranged the mass screw of 3 kinds of specifications---moderate-length mass screw, short mass screw, long mass screw.
