The device is characterized by comprising a support rod, wherein the support rod is arranged on the circle surface of the motor and is not contacted with the circle surface and two end surfaces; a support seat is fixedly arranged on the end surface of the enclosure of the motor; a lever is connected with the support rod and the support seat; inner hexagonal setscrews and adjusting nuts matched with the inner hexagonal setscrews are screwed on the lever; and damping rubber blankets are arranged between the inner hexagonal setscrews and the end surface of the enclosure of the motor. Through implementation of the device of the invention, the noise and the vibration amplitude of the axial flux motor are reduced under the condition of not changing the structure of the existing axial flux motor. The device is simple to dismantle and install and is convenient for operation, and has enhanced practicability.
Description
Technical field
The present invention relates to the device that a kind of noise and vibration suppresses, especially for axial flux motor.
Background technology
The main cause that the axial flux motor noise and vibration produces 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 axial electromagnetic force wherein, and the size of axial 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 axial force 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 at the centre position in zone between the nodel line radially to two circumference pitch circles of the highest vibration shape of motor casing end face axial amplitude contribution and two, the i.e. screw active force at Zhen Dong crest place, can effectively reduce the amplitude of axial 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 the axial flux motor noise and vibration suppresses that is used for, its objective is axial 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 by the following technical programs:
A kind of device that is used for the inhibition of axial flux motor noise and vibration, it is characterized in that: described device comprise be positioned at the motor circumferential surface and with circumferential surface and the discontiguous support bar of both ends of the surface, supporting base is fixedly mounted on the motor casing end face, lever is connected with supporting base with support bar, hexagonal is adjusted screw and is adjusted the adjustment nut that screw matches with interior hexagonal in screwing on lever, adjusts between screw and the motor casing end face in interior hexagonal the damping rubber pad is installed.
Lever and support bar and supporting base are hinged.
Interior hexagonal adjusts screw, adjust quantity that nut and damping rubber pad install is to the circumferential pitch circle of the highest vibration shape of the amplitude contribution of motor casing end face and 2 times of the number of regions between the nodel line radially.
The quantity that interior hexagonal is adjusted screw, adjustment nut and the installation of damping rubber pad is 4 for each motor casing end face minimum number.
The installation site that interior hexagonal adjusts screw, adjust nut and damping rubber pad is under the electromagnetic force effect, to two circumferential pitch circles of the highest vibration shape of the amplitude contribution of motor casing end face and the radially centre position in zone, i.e. Zhen Dong crest place between the nodel line.
Advantage and effect:, can under the condition that does not change existing axial flux motor structure, reduce the amplitude of its noise and vibration by enforcement of the present invention.This device dismounting is simple, easy to operate, and practicality strengthens.
