Please refer to fig. 2-7.
The embodiment of the utility model provides a balancing piece, including the balancing piece main part and set up the bloop 110 in the balancing piece main part, the opening of bloop 110 is located the circumferential surface of balancing piece main part.
The embodiment of the utility model provides a balancing piece, when the compressor operation, the balancing piece is rotatory, through set up bloop 110 in the balancing piece main part, has reduced the noise that produces when the balancing piece, and then has reduced the whole noise of compressor.
The opening is located on an inner surface of the weight body. As shown in fig. 2 and 4, the balancer weight is fixed to the crankshaft, and therefore, the peripheral surface of the balancer weight main body has an inner surface close to the center of the crankshaft, an outer surface far from the center of the crankshaft, and two side end surfaces connecting the inner surface and the outer surface. In the rotation process of the balance weight, because the balance weight main body forms the concave structure, most of the air flow is in direct contact with the inner surface, therefore, the opening of the muffling hole 110 is preferably arranged on the inner surface of the balance weight main body, and the further muffling and noise reduction effects are achieved.
The opening of the muffling hole 110 can also be located on the outer surface or the side end surface of the balance weight body, so that the muffling and noise reducing effects can be achieved.
As shown in fig. 4, the muffling hole 110 includes an introduction passage 111 arranged in the direction perpendicular to the axial direction of the weight main body and a cavity 112 arranged in the axial direction of the weight main body; one end of the introduction passage 111 is an opening at the circumferential surface of the weight main body, and the other end of the introduction passage 111 communicates with the cavity 112. Through the arrangement, the gas introduced into the channel 111 forms an effect similar to the reciprocating motion of a piston under the action of pressure fluctuation; the gas entering the cavity 112 forms an effect similar to a spring, and the noise reduction effect is further improved.
Preferably, the introduction passage 111 is arranged in the radial direction of the weight body. With the above arrangement, the flow of the gas along the introduction passage 111 into the cavity 112 is facilitated, and the silencing effect is effectively improved.
The introduction passage 111 may be provided obliquely in the radial direction of the weight main body, and will not be described in detail.
In order to further improve the sound attenuation effect, the number of the introduction passages 111 is plural, and the included angle between two adjacent introduction passages 111 is the same. Through set up a plurality of leading-in passageways 111 of evenly arranging on the balancing piece main part, improved the effect to the even amortization of gas, further reached the effect that improves the noise cancelling effect.
In the present embodiment, the number of the introduction channels 111 is the same as that of the cavities 112, and the introduction channels correspond to the cavities one by one. That is, the number of the muffling holes 110 is plural, and each muffling hole 110 is composed of one introduction passage 111 and one cavity 112. Through the arrangement, the silencing holes 110 can be used for silencing corresponding parts, and the silencing effect is further improved.
It is also possible to make a plurality of introduction passages 111 communicate with one cavity 112. Wherein, only one cavity 112 may be provided on the weight main body, and the introduction channel 111 provided on the weight main body is all communicated with the cavity 112; it is also possible to provide a plurality of cavities 112, the number of cavities 112 being less than the number of introduction channels 111, each introduction channel 111 communicating with one cavity 112, and each cavity 112 communicating with a plurality of introduction channels 111.
It can be understood that, according to the principle of sound attenuation, the gas introduced into the passage 111 forms an effect similar to the reciprocating motion of the piston under the action of pressure fluctuation; the gas entering the cavity 112 has an effect similar to a spring, and due to the friction and damping effect of the gas during vibration, part of the sound energy of the gas is converted into heat energy to be dissipated, so that the pressure fluctuation of the gas becomes smoother, and the noise of the gas flow is reduced.
In order to ensure the sound deadening effect of the gas entering the cavity 112, the end of the cavity 112 communicates with the other end of the introduction passage 111. The gas entering the cavity 112 from the introduction channel 111 forms a one-way vibration damping and silencing effect, so that the gas turbulence is avoided, and the silencing effect is effectively improved. The other end of the introduction passage 111 may communicate with the middle portion of the cavity 112.
For ease of manufacture, the cavity 112 is a drilled circular hole configuration. The cavity 112 may also be directly machined during the fabrication of the weight body by injection molding or the like.
In this embodiment, the width of the introduction passage 111 is smaller than the diameter of the cavity 112. The gas entering the cavity 112 along the introducing channel 111 is diffused, the flow speed of the gas entering the cavity 112 is reduced, the energy of converting the sound energy into the heat energy is increased, and the silencing effect is further improved.
In particular, the amount of the solvent to be used,
