Alternatively, described cavity ringwise and arrange around described center hole.
Alternatively, described cavity is multiple, is uniformly distributed along described center hole, is interconnected between each described cavity.
Alternatively, described cavity is multiple, is uniformly distributed along described center hole, and described inlet is multiple, with each described cavity one_to_one corresponding respectively.
The utility model additionally provides a kind of air conditioner, and comprise wind wheel and drive the motor of described wind wheel, the both ends of the surface of described motor all have end cap, and at least one described end cap is arranged with above-mentioned motor damping ring.
Further, also comprise chassis, described chassis has holding cavity, and described motor to be placed in described holding cavity and to be fixed by a gland, and the output shaft of described motor stretches out that described holding cavity is outer to be fixedly connected with described wind wheel.
Further, the two end cap of described motor is all arranged with described motor damping ring.
In the utility model, when motor operate power is large, electric current is high, rotating speed is high, when vibrating large, motor oscillating is delivered to the noise suppression gas in cavity by the central hole of motor damping ring, then it is outside to be delivered to motor damping ring, in the process, the transmission of part noise needs noise suppression gas to transmit as medium, utilize the low transmission performance of noise suppression gas, noise is weakened greatly, thus reaches the effect of noise reduction; When this motor damping ring is applied to air conditioner, decrease motor oscillating transmission, weaken the resonance that air-conditioning inside causes, and then reduce the overall noise of air-conditioning, create more comfortable quiet air conditioner.

Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
It should be noted that, when element is called as " being fixed on " or " being arranged at " another element, it can directly on another element or may there is centering elements simultaneously.When an element is called as " being connected to " another element, it can be directly connected to another element or may there is centering elements simultaneously.
Also it should be noted that, the orientation term such as left and right, upper and lower in the present embodiment, is only relative concept or be reference with the normal operating condition of product each other, and should not be regarded as have restrictive.
With reference to Fig. 1, Fig. 2, the motor damping ring 10 that the utility model embodiment provides, comprises the body 11 of toroidal, body 11 is provided with center hole 12, be provided with cavity 13 in body 11, be injected with noise suppression gas in cavity 13, an end face of body 11 is provided with the inlet 14 that can be filled with for noise suppression gas.Body 11 adopts rubber material to make, and has certain thickness, and the size of cavity 13 is determined according to actual service condition, should have certain inhibitory action to noise, guarantees the demand of structural strength again simultaneously.Noise suppression gas is nitrogen, and nitrogen is inert gas, stable chemical nature, audio frequency conductivity is very low, only be equivalent to 1/5 of normal air, use nitrogen effectively can reduce the noise of motor in running as noise suppression medium, for improving the quiet degree successful run.
Particularly, cavity 13 ringwise and arrange around center hole 12.When motor damping ring 10 and motor assemble, assembled by center hole 12 and motor, like this, when motor is when vibrating, its vibration is directly passed to cavity 13 by center hole 12 to surrounding, then carries out vibration-absorbing denoising by the noise suppression gas in cavity 13.
In the present embodiment, cavity 13 is one, and inlet 14 is also one, can inject noise suppression gas by inlet 14 directly in cavity 13.Inlet 14 strictly seals, and guarantees that noise suppression gas can not overflow thus.Certainly, cavity 13 also can arrange multiple, and as centrally hole 12 is uniformly distributed, and inlet 14 is still one, is interconnected between each cavity 13, like this, also injects noise suppression gas by an inlet 14 by each cavity 13.
Also can be improved further on this basis, arrange multiple by cavity 13, centrally hole 12 is uniformly distributed, and is not communicated with between each cavity 13.Inlet 14 correspondence also arranges multiple, and each cavity 13 is corresponding with an inlet 14.
No matter adopt which kind of structure, as long as inject noise suppression gas in body 11, carry out vibration and noise reducing all within the utility model protection domain by noise suppression gas.
With reference to Fig. 3, Fig. 4, the utility model embodiment still provides a kind of air conditioner 20, and comprise wind wheel 21 and drive the motor 22 of wind wheel 21, the both ends of the surface of motor 22 all have end cap 221, and at least one end cap 221 is arranged with above-mentioned motor damping ring 10.As can be seen from Figure, two end caps 221 of motor 22 are equipped with motor damping ring 10.
Particularly, air conditioner 20 also comprises chassis 23, and chassis 23 has holding cavity 231, and it is interior and fixing by a gland 24 that motor 22 is placed in holding cavity 231.Two motor damping rings 10 are just stuck in holding cavity 231, also play the effect of fixed electrical machinery 22.The output shaft 222 of motor 22 stretches out outside holding cavity 231 and is fixedly connected with wind wheel 21.When air conditioner 20 works, motor 22 drives wind wheel 21 to rotate, especially when motor 22 operate power is large, electric current is high, rotating speed is high, when vibrating large, motor 22 vibrates the noise suppression gas be delivered to by center hole 12 place of motor damping ring 10 in cavity 13, be delivered to motor damping ring 10 outside, be finally delivered on air-conditioning, produce resonance and noise.In the process, the transmission of a part of noise needs noise suppression gas to transmit as medium, utilizes the low transmission performance of noise suppression gas, noise is weakened greatly, thus reaches the effect of noise reduction.
These are only preferred embodiment of the present utility model, not in order to limit the utility model, all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
