Abstract
The utility model relates to a balancing block device for a rotor of a variable frequency motor, and the utility model relates to frequency motors. In view of the shortages that the existing motor rotor is formed by that the prolongation of an aluminum-casting end ring of the rotor is provided with an aluminous molten balancing post; when balance is corrected, a steel washer is additionally arranged on the balancing post; at the time of high-speed rotation, the balance post is easy to fall off, causing unsafe factors; meanwhile, one end of the aluminum-casting end ring of the rotor forms a fan wing shape; at the time of high-speed rotation, the aluminum-casting end ring can generate resistance force, can consume of energy resource, and can affect the rotary speed of the variable frequency motor, etc. The balancing block device for the rotor of the variable frequency motor is provided; the utility model has simple structure, and adopts a steel balancing ring which takes steel material as weight-reducing material when a weight-reducing method is used for correcting balance; the structural reliability of a motor is higher than the structural reliability of the motor which takes aluminum as the weight-reducing material. The utility model has the technical scheme that an aluminum-casting rotor 2 is arranged on a rotating shaft 3; both end surface of the aluminum-casting rotor 2 of the utility model are provided with round annular steel balancing rings 1.
Description
One, technical field
The utility model relates to variable-frequency motor, especially a kind of rotor balancing block assembly of variable-frequency motor.
Two, background technology
Motor rotor is normally at the prolongation of casting aluminum rotor end ring, design is by the balance columns of aluminium matter casting, on balance columns, add the steel packing ring during smoothing weighing apparatus, to reach the aequum of motor rotor, this method is feasible at the alignment rotating speed less than the motor of 3000 γ/min, and need rotate higher rotation speed usually for variable-frequency motor the time, as when being higher than 3000 γ/min, balance columns easily taking place come off, causes unsafe factor; It is wing that an end of casting aluminum rotor end ring is fan simultaneously, when high rotating speed, can form resistance, and consumes energy influences weak points such as variable-frequency motor rotating speed.
Three, summary of the invention
The purpose of this utility model provides a kind of simple in structure, the steel gimbal that goes heavy material the when conduct of employing steel material goes heavy method smoothing to weigh, and the structural reliability of motor is removed the rotor balancing block assembly of the variable-frequency motor of heavy material far above the conduct of aluminium matter.
Technical scheme that the purpose of this utility model adopts is, includes in the rotating shaft axle and goes up a device cast-aluminum rotor is arranged, and the both ends of the surface of its cast-aluminum rotor have the steel gimbal that is annular.
Because the utility model adopts the steel gimbal, it is the amount of on the steel gimbal, removing excess stock, to reach the stationarity that adapts to high speed rotating, the proportion of aluminium matter the chances are 1/3rd of steel as everybody knows, therefore the amount removed of aluminium matter gimbal, much larger than than the amount of removing the steel gimbal, this brings harmful effect can for the reliability and the performance of rotor structure, therefore at the steel gimbal amount method smoothing weighing apparatus that gets on, the reliability and the performance of motor are guaranteed, dynamically balanced precision has also improved, and the vibration of motor such as also reduces at characteristics.
Four, description of drawings
Further specify the utility model below in conjunction with accompanying drawing.
Accompanying drawing is the utility model structural representation.
Among the figure: 1-steel gimbal 2-cast-aluminum rotor 3-rotating shaft
Five, embodiment
As shown in drawings, device is gone up in 3 of rotating shafts cast-aluminum rotor 2, and the both ends of the surface of cast-aluminum rotor 2 have the steel gimbal 1 that is annular.
Steel gimbal 1 all adopts the interference mechanical engagement with rotating shaft 3 and cast-aluminum rotor 2 with rotating shaft 3, makes whole rotor to rotate together.
Claims (1)
1, a kind of rotor balancing block assembly of variable-frequency motor includes that device has cast-aluminum rotor (2) on rotating shaft (3) axle, it is characterized in that the both ends of the surface of cast-aluminum rotor (2) have the steel gimbal (1) that is annular.
