Abstract
The invention relates to a device for suppressing the noise and the vibration of a radial flux motor. The device is characterized by comprising a metal supporting ring which is mounted on the periphery of the motor and can open and close around a pin shaft without contacting the circumferential surface of the shell of the motor, a hexagonal socket adjusting screw and an adjusting nut matched with the hexagonal socket adjusting screw are screwed in the supporting ring, and a damping rubber insert is mounted between the hexagonal socket adjusting screw and the circumferential surface of the shell of the motor. The invention can be implemented to lessen the noise and reduce the vibration amplitude of the radial flux motor under the condition of unchanging the structure of a traditional radial flux motor. The device is easy to mount and dismount and convenient to operate and has strong practicability.
Description
Technical field
The present invention relates to the device that a kind of noise and vibration suppresses, especially for the radial flux motor.
Background technology
The main cause that radial flux electric moter noise and vibration produce is to produce electro-magnetic exciting force by electromagnetic field to involve its harmonic wave the excitation of mechanical structure is caused, having the greatest impact of radial electromagnetic force wherein, and the size of radial electromagnetic force is relevant with the Reeb exponent number.A low noise motor should be that the air-gap field harmonic component is little, and the radial load wave amplitude of generation is little, the exponent number height, and the electromagnetic force wave frequency prevents resonance away from the natural frequency of stator.But be difficult to all satisfy above-mentioned requirements during design.The device that a kind of noise and vibration of the present invention suppresses, by being adjusted under the electromagnetic force effect, at motor casing circumferential surface (1) the radially centre position in zone, i.e. the screw active force at Zhen Dong crest place between two axial nodel lines of the highest vibration shape of amplitude contribution and two the circumference pitch circles.Can effectively reduce the amplitude of radial flux motor casing vibration, increase its damping and reduce noise radiation.
Summary of the invention
Goal of the invention: the invention provides a kind of device that is used for radial flux electric moter noise and vibration suppression, its objective is radial flux motor, the measure and the method that reduce noise and vibration are provided into the specific (special) requirements occasion.
Technical scheme: the present invention implements according to following technical scheme:
A kind of device that is used for radial flux electric moter noise and vibration suppression is characterized in that: described device comprise be installed in the motor circumferencial direction can be around the metal supporting rings of bearing pin folding, metal supporting rings does not contact with the motor casing circumferential surface; Hexagonal is adjusted screw and is adjusted the adjustment nut that screw matches with interior hexagonal in screwing on support ring, adjusts between screw and the motor casing circumferential surface in interior hexagonal the damping rubber pad is installed.
The installation quantity that interior hexagonal adjusts screw, adjust nut and damping rubber pad is under the electromagnetic force effect, and the motor casing circumferential surface is 2 times of quantity that multiply by support ring again of the highest circumferential vibration shape number of amplitude contribution radially.
The installation quantity that interior hexagonal is adjusted screw, adjustment nut and damping rubber pad is that minimum number is 4.
The support ring of motor circumferencial direction is 2 times to the highest axial vibration shape number of the radially amplitude contribution of motor in the quantity of motor axially-aligned.
The installation site that interior hexagonal is adjusted screw, adjustment nut and rubber blanket is under the electromagnetic force effect, to motor casing the circumferential surface radially centre position in zone, i.e. Zhen Dong crest place between two axial nodel lines of the highest vibration shape of amplitude contribution and two the circumference pitch circles.
Advantage and effect:, can under the condition that does not change existing radial flux electric motor structure, reduce the amplitude of its noise and vibration by enforcement of the present invention.This device dismounting is simple, easy to operate, practical.
