Referring to fig. 1, in an embodiment of the present application, a vibration absorbing apparatus 100 is provided, which includes a fixing portion 110, an axial weight portion 120, a radial weight portion 130, a plurality of axial vibration absorbing members 140, and a plurality of radial vibration absorbing members 150. The fixing portion 110 has a first axis and is configured to be coaxially mounted on the vibrating body. The axial weight portion 120 is disposed at one axial end of the fixing portion 110 and is disposed around the first axis. The radial weight portions 130 are circumferentially arranged along the circumferential direction of the fixing portion 110. Each of the axial vibration absorbing members 140 is connected between the axial weight portion 120 and the fixing portion 110 in the axial direction of the fixing portion 110, and a plurality of the axial vibration absorbing members 140 are arranged at intervals in the circumferential direction of the fixing portion 110 around the first axis. Each of the radial vibration absorbing members 150 is connected between the radial weight portion 130 and the fixing portion 110 in the radial direction of the fixing portion 110, and a plurality of the radial vibration absorbing members 150 are arranged at intervals in the circumferential direction of the fixing portion 110 around the first axis.
In actual operation, the vibration absorbing device 100 is coaxially mounted on a vibrating body (such as a compressor) through the fixing portion 110, and the natural frequency of the vibration absorbing device 100 is made to be the same as the natural frequency of the vibrating body by properly setting the weights and the rigidities of the axial weight portion 120, the radial weight portion 130, the axial vibration absorbing member 140, and the radial vibration absorbing member 150. When the vibrating body vibrates, the vibration absorption device 100 is driven to vibrate together, and the motion inertia force of the vibration absorption device 100 is reacted to the vibrating body by utilizing the anti-resonance principle, so that the effect of inhibiting the vibration of the vibrating body is achieved. In the vibration reduction process, the axial weight part 120 and the axial vibration absorbing member 140 absorb and attenuate the vibration of the vibration body in the axial direction, and the radial weight part 130 and the radial vibration absorbing member 150 absorb and attenuate the vibration of the vibration body in a plurality of radial directions, so that the three-way vibration reduction effect is achieved. Compared with the prior art, the vibration absorbing device 100 has a compact structure and occupies a small space.
It should be understood that the reference to "three directions" in the embodiments of the present application refers to three directions perpendicular to each other, specifically, to an axial direction and two radial directions. Wherein the fixing part 110 is connected to the axial weight part 120 through the axial shock absorber 140, and the fixing part 110 is connected to the radial weight part 130 through the radial shock absorber 150.
Preferably, the axial vibration absorbing member 140 and the radial vibration absorbing member 150 are made of rubber, which has low cost and good vibration absorbing effect. Of course, the axial shock absorbing member 140 and the radial shock absorbing member 150 may also take other configurations, such as a spring, a balloon, a silicone gel, etc., and the specific form is not limited.
In some embodiments, the axial shock absorbing member 140 is detachably connected to the axial weight portion 120, and the axial shock absorbing member 140 is detachably connected to the fixing portion 110. The radial vibration absorbing member 150 is detachably connected to the radial weight portion 130, and the radial vibration absorbing member 150 is detachably connected to the fixing portion 110.
In actual operation, when the vibration absorbing frequency of the vibration absorbing apparatus 100 needs to be adjusted, the existing axial vibration absorbing member 140 and/or radial vibration absorbing member 150 can be removed, and the axial vibration absorbing member 140 and/or radial vibration absorbing member 150 with different stiffness can be reinstalled to adjust the frequency of the whole vibration absorbing apparatus 100 in all directions, so as to achieve the three-way tuning effect. It will be understood that when the radial shock absorber 150 is detached from the radial weight portion 130 and from the fixing portion 110, the radial weight portion 130 is detached from the fixing portion 110. When the axial vibration absorbing member 140 is detached from the axial weight portion 120 and from the fixing portion 110, the axial vibration absorbing member 140 is detached from the fixing portion 110.
It will be appreciated that vibration absorbers of different stiffness (including the axial vibration absorber 140 and the radial vibration absorber 150) will result in vibration absorbers having different vibration absorption frequencies. For example, when the shock absorbing member is a rubber member, the rigidity of the shock absorbing member can be changed by adopting rubbers of different materials. The stiffness of the individual shock absorbers may be the same or different.
Preferably, the axial shock absorbing member 140 is detachably coupled with the axial weight portion 120 and the fixing portion 110 by a screw coupling. The radial shock absorbing member 150 is detachably coupled to the radial weight portion 130 and the fixing portion 110 by a screw coupling. The threaded connection piece is utilized for connection, so that the device is economical and practical, has a simple structure and is convenient to disassemble and assemble. The threaded connecting piece is a bolt or a screw and the like.
Specifically, referring to fig. 2, 3 and 4, the fixing portion 110 has an axial positioning groove 113 on a side facing the axial weight portion 120, and the axial weight portion 120 has a first positioning groove 123 on a side facing the fixing portion 110. One end of the axial vibration absorbing member 140 is detachably inserted into the axial positioning groove 113, and the other end is detachably inserted into the first positioning groove 123.
And/or, the fixing portion 110 has a radial positioning groove 114 on a side facing the radial weight portion 130, and the radial weight portion 130 has a second positioning groove 133 on a side facing the fixing portion 110. One end of the radial shock absorber 150 is detachably fitted in the radial positioning groove 114, and the other end is detachably fitted in the second positioning groove 133.
In the present embodiment, the axial shock absorbing member 140 is positioned and installed by the first positioning groove 123 and the axial positioning groove 113, and the radial shock absorbing member 150 is positioned and installed by the second positioning groove 133 and the radial positioning groove 114. At the moment, each vibration absorbing piece is positioned through each positioning groove, and the installation of each vibration absorbing piece is facilitated.
The way of detachably connecting the axial vibration absorbing member 140 with the first positioning groove 123 and the axial positioning groove 113 may be to connect the axial vibration absorbing member 140 with the first positioning groove 123, and connect the axial vibration absorbing member 140 with the axial positioning groove 113 by using threaded connectors. Alternatively, the axial vibration absorbing member 140 is detachably connected to the first positioning groove 123 and the axial positioning groove 113 by other methods such as a bayonet lock. Similarly, the way of detachably connecting the radial vibration absorbing member 150 to the second positioning groove 133 and the radial positioning groove 114 may be to connect the radial vibration absorbing member 150 to the second positioning groove 133, and connect the radial vibration absorbing member 150 to the radial positioning groove 114 by using threaded connectors. Alternatively, the radial shock absorbing member 150 is detachably connected to the second positioning groove 133 and the radial positioning groove 114 by other methods such as interference clamping.
Specifically, a first protrusion 124 is protruded from one side of the axial weight portion 120 facing the fixing portion 110, and the first protrusion 124 has a first positioning groove 123. A second protrusion 134 is protruded from a side of the radial weight 130 facing the fixing portion 110, and the second protrusion 134 has a second positioning groove 133.
In some embodiments, referring to fig. 1, 3 and 4, the axial weight portion 120 includes an axial weight ring 121 disposed at one axial end of the fixing portion 110 and disposed coaxially with the fixing portion 110, and each axial vibration absorbing member 140 is connected between the axial weight ring 121 and the fixing portion 110 along the axial direction of the fixing portion 110.
And/or, the radial weight part 130 includes a radial weight ring 131, the radial weight ring 131 is circumferentially arranged along the circumference of the fixing part 110, and each radial shock absorbing member 150 is connected between the radial weight ring 131 and the fixing part 110 along the radial direction of the fixing part 110.
At this time, the axial weight ring 121 is engaged with the axial vibration absorbing member 140 to perform vibration damping in the axial direction, and the radial weight ring 131 is engaged with the radial vibration absorbing member 150 to perform a plurality of vibration damping in the radial direction. Meanwhile, the axial weight block 122 and the radial weight block 132 are annular, so that the fixing portion 110 is more conveniently installed and connected, and the installation space is saved.
Preferably, the radial counterweight ring 131 is arranged coaxially with the fixed part 110. In actual use, the radial vibration absorbing members 150 have the same size and different materials, and frequency modulation is realized due to the different materials during replacement, but the relative distance between the radial weight ring 131 and the fixing portion 110 is kept constant and is coaxially arranged. Of course, it is not excluded to replace the radial vibration absorbing members 150 with different sizes (different lengths in the radial direction) for the purpose of tuning the frequency, so as to change the relative positional relationship (in an eccentric arrangement) between the radial counterweight ring 131 and the fixing portion 110, for example, in the case that the center of gravity of the compressor 200 is not on the first axis, the radial counterweight ring and the fixing portion 110 are eccentrically arranged, and the compressor 200 can be balanced to prevent the compressor 200 from tilting.
In some embodiments, referring to fig. 1, the axial weight portion 120 further includes a plurality of axial weights 122, each axial weight 122 is disposed on the axial weight ring 121, and the plurality of axial weight rings 121 are disposed around the first axis at intervals along the circumferential direction of the fixing portion. And/or, the radial weight portion 130 further includes a plurality of radial weights 132, each radial weight 132 is disposed on the radial weight ring 131, and the plurality of radial weights 132 are spaced apart from each other along the circumferential direction of the fixing portion 110 around the first axis.
In the present embodiment, each weight portion (including the axial weight portion 120 and the radial weight portion 130) further includes a weight block (including the axial weight block 122 and the radial weight block 132) disposed on each weight ring, and the weight of the vibration absorbing device 100 in each direction is adjusted by using the setting position of the weight block, which helps to enhance the vibration absorbing effect of the vibration absorbing device 100.
The axial weight 122 and the radial weight 132 may be both made of metal. The metal material has a high density, and the weight of the weight member having the same weight has a small volume, which contributes to reducing the space occupied by the vibration absorbing device 100.
