Abstract
The utility model provides a high-precision balancing device for a low-vibration motor. The high-precision balancing device comprises a dynamic balancing machine, a security support and a driving belt, wherein the security support and the driving belt are arranged on the dynamic balancing machine, the security support is provided with a connection crossbeam, the driving belt is in transmission connection with the dynamic balancing machine, and the dynamic balancing machine is provided with a control cabinet through a signal line. The high-precision balancing device provided by the utility model has a simple structure; a motor rotor employing the high-precision balancing device for dynamic balance verification has high balance precision, residual unbalance of the rotor is lower than 50 mg, and a balance rotating speed reaches a normal work rotating speed of a workpiece; after assembling of the motor, vibration acceleration, a vibration speed and an energy value of the motor during normal operation are substantially increased, vibration acceleration reaches 0.3 mm/s2, the integral vibration speed is lower than 0.1 mm/s, so a vibration value of the motor during normal operation is reduced, harm brought by vibration of the motor is effectively eliminated, product quality is improved, and operation of the motor is more reliable.
Description
Technical field
The utility model belongs to motor manufacturing technology field, the particularly high-accuracy bascule of a kind of low vibrating motor.
Background technology
As everyone knows, the rotor dynamic balancing of motor adopts commonsense method to carry out usually, this method normally is placed on the rotor of motor on two support rollers, and using universal coupling to connect the axle body of rotor, the remaining amount of unbalance to rotor after rotating speed reaches 600-900r/min is proofreaied and correct.The major defect of said method is: 1, balancing equipment can not reach the working speed of motor, and there is larger deviation in the balance drive mode of motor; 2, the rotating speed of balance is lower, and balance mass is difficult to the precision that reaches higher; 3, balance method defectiveness is depended merely on the requirement that the method that increases the weight of can not effectively satisfy low vibrating motor.At present, although take certain measure to improve constantly balance quality of rotor, the overall operation effect of low vibrating motor is still not ideal.
The utility model content
The utility model provides a kind of high-accuracy bascule of low vibrating motor with can effectively improving balance quality simple in structure.
For achieving the above object, the technical solution of the utility model is: the high-accuracy bascule of a kind of low vibrating motor, comprise emergency support and driving belt on dynamic balancing machine and dynamic balancing machine, emergency support is provided with connecting cross beam, drives belt and dynamic balancing machine and is in transmission connection; Dynamic balancing machine is provided with control cubicle by holding wire.
Described dynamic balancing machine and emergency support outside are provided with protective cover.
Compared with prior art, the utility model has the advantages that:
1, the utility model comprises the emergency support and driving belt on dynamic balancing machine and dynamic balancing machine, and emergency support is provided with connecting cross beam, drives belt and dynamic balancing machine and is in transmission connection; Dynamic balancing machine is provided with control cubicle by holding wire, and it is simple in structure, adopts the utility model to carry out the rotor of dynamic balance check, and balance quality is high, and the remaining amount of unbalance of its rotor can reach below 50mg, and balancing speed can reach the normal operation rotating speed of workpiece; After the motor assembling, vibration acceleration, vibration velocity and energy value during its normal operation improve greatly, the vibration acceleration performance can reach 0.3mm/s 2, complete machine oscillation speed can reach below 0.1mm/s, thereby the vibration values in the time of can reducing motor and normally move, effectively eliminate the harm that motor oscillating brings, improve the quality of products, make the motor operation more reliable.
2, dynamic balancing machine and emergency support outside are provided with protective cover, can effectively improve the device security coefficient, prevent that contingency from occuring.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of emergency support in Fig. 1.
Embodiment
The high-accuracy bascule of low vibrating motor as depicted in figs. 1 and 2, it comprises emergency support 2 and driving belt 3 on dynamic balancing machine 1 and dynamic balancing machine 1, be provided with connecting cross beam 4 on emergency support 2, drive belt 3 and be in transmission connection with dynamic balancing machine 1, drive belt 3 and provide power by dynamic balancing machine 1 motor internal.For the ease of controlling, improving balance quality, dynamic balancing machine 1 is provided with control cubicle 6 by holding wire 5.Outside at dynamic balancing machine 1 and emergency support 2 is provided with protective cover 8, and protective cover 8 can improve the device security coefficient, prevents that contingency from occuring.
The utility model adopts dynamic balance method to carry out balance to workpiece 7, its course of work is: workpiece 7 is placed on connecting cross beam 4, and by driving the fastening workpiece 7 of belt 3, fixing half bond 9 in the keyway of workpiece 7 axle body left ends, with protective cover 8 lockings, to guarantee safety; Start dynamic balancing machine 1, under the balancing speed of setting, dynamic balancing machine 1 is carried out IC and demarcate, then improve gradually the working speed that balancing speed reaches rotor; Press demonstration phase place and quality that equipment operating handbook regulation is observed amount of unbalance on dynamic balancing machine 1, close dynamic balancing machine 1, stop motor and with its rotor braking, select suitable balance weight to be placed on corresponding position by balancing machine indication phase place; When remaining amount of unbalance hour, adopt and go the rotor of heavy method balance not allow to affect motor performance and structural strength; Repeatedly carry out above step until remaining amount of unbalance is controlled at below 50mg, then workpiece 7 is hung dynamic balancing machine 1, the balance end-of-job.
By the rotor dynamic balance check that the utility model carries out, the remaining amount of unbalance of rotor can reach below 50mg, and balancing speed can reach the normal operation rotating speed of workpiece; After the motor assembling, in conjunction with the improvement of other factors, complete machine oscillation speed can reach below 0.1mm/s, and the vibration acceleration performance reaches 0.3mm/s 2, thereby can effectively eliminate the harm that motor oscillating brings, and makes the motor operation more reliable.
