Abstract

The invention discloses a rotor balance disk for a three-phase asynchronous motor, and relates to a rotor balance disk for high-voltage motors and low-voltage high-power motors, in particular to a balance disk used on rotors of Y and Y2-355-630 high-voltage/low-voltage high-power motors. The rotor balance disk comprises a balance disk body. A round through groove is formed in the center of the balance disk body and a plurality of through holes which are evenly distributed along the circumference of the balance disk body are formed in the balance disk body. A plurality of threaded holes which are evenly distributed along the outer side of the circumference are further formed in the balance disk body, and the threaded holes are located outside the through holes. The rotor balance disk for the three-phase asynchronous motor is simple to machine, convenient to operate, short in period, low in cost and high in working efficiency.

Description

A kind of threephase asynchronous machine rotor balancing disc

Technical field

The present invention relates to a kind of high-voltage motor and low-pressure high-power rotor for electromotor balancing frame, specifically for the rotor of high-voltage motor and low-pressure high-power motor Y, Y2-355 ~ 630 motor.

Background technology

As shown in Figure 1-2, due to original traditional design consider not comprehensive, nonstandardization, auxiliary component is bad to be done, and uses inconvenient operation, often occurs some problems, efficiency is low; At present this kind ofly improves design and can meet above deficiency.Be widely used at present on the motor rotor in the fields such as industry, agricultural, business, building industry and traffic.

Rotor is the key components and parts in motor, and on natural rotor, the structural design of balancing frame is also very important, and its geomery, size etc. have a direct impact the efficiency of the processing and fabricating of motor, cycle length etc.And use in the market maximum Y, Y2 series high voltage motor and low-pressure high-power motor, its epitrochanterian balancing disc structure adopts Fig. 1, because the balancing frame of Fig. 1 will be processed one with the cannelure of tapering, and during dynamic balance checking, the balance weight of being furnished with Fig. 2, the good dynamic balancing in rotor school must be arrived Fig. 3, and the order 1 in Fig. 3 is balancing frame, sequence number 2 is balance weight, and sequence number 3 is hold-down screw; Due to the manufacturing process of Fig. 1, Fig. 2, without meeting existing need of production, and in manufacturing process, processing difficulties, the cycle is long, and cost is high, employee's troublesome poeration, the time is long.

Summary of the invention

The object of the invention is to overcome above-mentioned weak point, thereby a kind of high-voltage motor and low-pressure high-power rotor balancing disc structure is provided, is the rotor of Y, Y2-355 ~ 560 high-low pressure motor for center height specifically.

According to technical scheme provided by the invention, a kind of threephase asynchronous machine rotor balancing disc, comprises balancing frame, and described balancing frame central authorities are a circular groove, are provided with several along the through hole of even circumferential branch on balancing frame;

On described balancing frame, also along the even branch of periphery, have several screwed holes, described screwed hole is positioned at the outside of through hole.

On described screwed hole, be fixed with a balancing bolt, one end of balancing bolt is disposed with equalizing wahser, spring washer, and is fixed on balancing frame by Self-lock nut.

Beneficial effect of the present invention: the present invention processes simply, and easy to operate, the cycle is short, and cost is low, and operating efficiency is high.

Fig. 3 is the structural representation after this good dynamic balancing in practical former rotor school;

Fig. 4 is rotor balancing disc structural representation of the present invention;

Fig. 5 is the structural representation after the good dynamic balancing in rotor of the present invention school.

Embodiment

As in Figure 3-5, a kind of threephase asynchronous machine rotor balancing disc, comprises balancing frame 1, and described balancing frame 1 central authorities are a circular groove 7, is provided with several along the through hole 6 of even circumferential branch on balancing frame 1;

On described balancing frame 1, also along the even branch of periphery, have several screwed holes 8, described screwed hole 8 is positioned at the outside of through hole 6.

On described screwed hole 8, be fixed with a balancing bolt 2, one end of balancing bolt 2 is disposed with equalizing wahser 3, spring washer 4, and is fixed on balancing frame 1 by Self-lock nut 5.

The present invention carries out improvedly on the basis of Fig. 1-2, and it cancels the cannelure with tapering, the screw of processing 12-M10.During calibration balance, press shown in Fig. 5,1 is balancing frame, and 2 is balancing bolt (M10X40), and 3 is equalizing wahser, and 4 is spring washer (10), and sequence number 5 is Self-lock nut (M10).

Wherein balancing bolt 2, equalizing wahser 3, spring washer 4 and Self-lock nut 5 are standard component, just fairly simple in the process of whole dynamic balance checking like this, as long as the balancing frame of Fig. 4 of processing, all the other are standard component, save a large amount of time to buying, making, shorten fabrication cycle.

So whole rotor balancing disc, processing is simple, and easy to operate, the cycle is short, and cost is low, and operating efficiency is high.
