Description

Technical Field

The bottom of the housing is provided with feet for attachment to a mounting base of the appliance to support the compressor on the mounting base. When the compressor is in operation, the motor and the compression mechanism can vibrate in operation, and the vibration can be conducted to the mounting seat from the machine shell to the bottom plate, so that larger noise and vibration are generated, and even the risk of resonance is caused.

For the vibration energy that the decay compressor produced, current compressor damping system mainly comprises rubber foot pad, sleeve, bolt, and its mounting means does, inlays the compressor footing into the recess that rubber foot pad corresponds, and the compressor bolt passes the sleeve and fixes rubber foot pad on the mount pad.

Referring to fig. 1 and 2, a shock absorbing foot pad 100 provided herein will now be described. The vibration-damping foot pad 100 comprises a housing 20, a shaft core 10, an inner magnetic ring 40, an outer magnetic ring 30 and a leaf spring 50. An inner cavity 201 is formed in the housing 20, and one end of the inner cavity 201 is open, and one end of the shaft core 10 extends into the inner cavity 201.

The inner ring 40 is mounted on the shaft core 10, the inner ring 40 is supported by the shaft core 10, and the inner ring 40 is coaxially disposed with the shaft core 10. The leaf spring 50 is mounted on the housing 20, and the leaf spring 50 is supported by the housing 20. The shaft core 10 is connected with the leaf spring 50, so that the shaft core 10 is movably supported in the inner cavity 201 of the outer shell 20 through the leaf spring 50, and the inner magnetic ring 40 is movably supported in the inner cavity 201 of the outer shell 20.

The outer magnet ring 30 is fixed to the housing 20, and the outer magnet ring 30 is installed in the inner cavity 201, thereby supporting the outer magnet ring 30 by the housing 20.

The outer magnetic ring 30 is arranged around the inner magnetic ring 40, so that the inner magnetic ring 40 and the outer magnetic ring 30 are matched to form a damping structure, and high-frequency axial vibration can be isolated.

The shaft core 10 is disposed coaxially with the outer magnetic ring 30, that is, the plate spring 50 supports the shaft core 10 at the center of the outer magnetic ring 30 so that the shaft core 10 is coaxial with the outer magnetic ring 30 and the shaft core 10 is coaxial with the inner magnetic ring 40, the inner magnetic ring 40 can be coaxial with the outer magnetic ring 30, and thus the inner magnetic ring 40 can be balanced by the magnetic force in the circumferential direction of the outer magnetic ring 30.

Because the plate spring 50 supports the shaft core 10, the shaft core 10 can move axially in the inner cavity 201, and the plate spring 50 can also play a role in resetting, and in addition, the inner magnetic ring 40 can also drive the shaft core 10 to reset under the magnetic action of the outer magnetic ring 30 on the inner magnetic ring 40.

In addition, the leaf spring 50 supports the shaft core 10, and when the shaft core 10 vibrates in the radial direction, the leaf spring 50 can also play a certain role in buffering, so that the shaft core 10 is prevented from directly contacting the shell 20, further the radial vibration of the shaft core 10 is prevented from being directly transmitted to the shell 20, and a certain radial vibration damping effect is played.

The shaft core 10 and the outer magnetic ring 30 are coaxially arranged, when the axial middle surface of the inner magnetic ring 40 is superposed with the axial middle surface of the outer magnetic ring 30, two ends of the inner magnetic ring 40 are balanced by the magnetic force of the outer magnetic ring 30, and the rigidity of a vibration damping structure formed by the inner magnetic ring 40 and the outer magnetic ring 30 is very small and close to zero near the balance point; near this equilibrium position, the leaf spring 50 is also close to the free state, so that the stiffness of the entire vibration-damping footpad 100 is small and close to zero, forming a quasi-zero stiffness structure. And under the dual function of piece formula spring 50 and outer magnetic ring 30, can make interior magnetic ring 40 and axle core 10 be in the ideal balanced position that dynamic stiffness is close zero all the time along the axial, can play good vibration isolation effect to axial low frequency vibration, and then realize quasi-zero rigidity damping, and then make this damping callus on the sole 100 all have good damping effect to low frequency and high frequency vibration, guarantee the good damping effect of this damping callus on the sole 100.

The above "vicinity" means: the axial middle surface of the inner magnetic ring 40 coincides with the axial middle surface of the outer magnetic ring 30, and the distance between the axial middle surface of the inner magnetic ring 40 and the vicinity of the axial middle surface of the outer magnetic ring 30 is small, that is, the axial middle surface of the inner magnetic ring 40 coincides with the axial middle surface of the outer magnetic ring 30 is an ideal state, but a certain error or deviation is allowed, for example, the distance of the error or deviation is less than 15% of the axial maximum amplitude of the object to be vibration-isolated, and certainly, in some occasions with high precision requirements, the distance of the error or deviation is less than 10% or less than 5% of the axial maximum amplitude of the object to be vibration-isolated.

Compared with the prior art, the damping foot pad 100 provided by the embodiment of the application has the advantages that the inner magnetic ring 40 is mounted on the shaft core 10, the outer magnetic ring 30 is arranged on the periphery of the inner magnetic ring 40, and the high-frequency severe vibration can be well isolated under the action of the magnetic force between the inner magnetic ring 40 and the outer magnetic ring 30; the plate spring 50 supports the shaft core 10, so that the shaft core 10, the inner magnetic ring 40 and the outer magnetic ring 30 are coaxially arranged, when the axial middle surface of the inner magnetic ring 40 is superposed with the axial middle surface of the outer magnetic ring 30, two ends of the inner magnetic ring 40 are balanced by the magnetic force of the outer magnetic ring 30, and the rigidity of the vibration reduction foot pad 100 is very small and close to zero near the balance position; under the action of the plate spring 50 and the outer magnetic ring 30, the inner magnetic ring 40 and the shaft core 10 are always in an ideal balance position with dynamic stiffness close to zero along the axial direction, so that good vibration isolation effect can be achieved on axial low-frequency vibration, quasi-zero stiffness vibration reduction is further achieved, and good vibration reduction effect on low-frequency and high-frequency vibration is achieved; in addition, the sheet spring 50 is used for supporting the shaft core 10, and the sheet spring 50 can also reduce radial vibration, reduce the transmission of the radial vibration to the casing 20, and also can play a role in radial vibration damping. The axially intermediate surface of the inner ring 40 is a surface that passes through the center of the inner ring 40 in the axial direction and is perpendicular to the axial direction of the inner ring 40. The axial intermediate surface of the outer magnet ring 30 refers to a surface that passes through the center of the axial direction of the outer magnet ring 30 and is perpendicular to the axial direction of the outer magnet ring 30.

The inner magnetic ring 40 and the outer magnetic ring 30 have the same magnetizing direction, that is, the inner magnetic ring 40 and the outer magnetic ring 30 are both radially magnetized from the central axis to the outside, or the inner magnetic ring 40 and the outer magnetic ring 30 are both internally magnetized from the outside of the rings. That is, when the radially inner side or inner periphery of the inner magnetic ring 40 is an N pole and the radially outer side or outer periphery of the inner magnetic ring 40 is an S pole, the radially inner side or inner periphery of the outer magnetic ring 30 is an N pole and the radially outer side or outer periphery of the outer magnetic ring 30 is an S pole; or, when the radial inner side or inner circumference of the inner magnetic ring 40 is an S pole and the radial outer side or outer circumference of the inner magnetic ring 40 is an N pole, the radial inner side or inner circumference of the outer magnetic ring 30 is an S pole and the radial outer side or outer circumference of the outer magnetic ring 30 is an N pole, so that the inner magnetic ring 40 and the outer magnetic ring 30 attract each other under the action of respective generated magnetic fields, and when vibration is transmitted to the shaft core 10 to push the shaft core 10 to move axially, vibration is reduced due to the attraction between the inner magnetic ring 40 and the outer magnetic ring 30, and a damping effect is achieved.
