The present invention proposes a vibration-damping pad which can be used in compressors, in particular reciprocating compressors, which can be used in refrigeration equipment such as refrigerators. The compressor is provided with a base 41, the base 41 is connected with the refrigeration equipment, and the vibration damping pad is arranged between the base 41 of the compressor and the inner wall of the refrigeration equipment. The vibration damping pad can also be used for other equipment which is easy to vibrate during movement, so that the transverse vibration generated during the operation of the equipment is reduced. Fig. 1 to 3 are corresponding drawings of an embodiment of the present invention.
Referring to fig. 1, in one embodiment, the damping pad includes:
the damping pad comprises a damping pad body 10, wherein the damping pad body 10 is provided with a first surface 11 and a second surface 12 which are oppositely arranged, the damping pad body 10 is provided with a mounting hole 21, and the mounting hole 21 is communicated with the first surface 11 and the second surface 12 of the damping pad body 10; in order to improve the damping effect, the damping pad body 10 may be a cylindrical structure as a whole, and the first surface 11 and the second surface 12 are two end surfaces of the damping pad body 10. When the vibration damping pad is matched with the compressor, the first surface 11 of the vibration damping pad main body 10 faces the base 41 of the compressor, the second surface 12 of the vibration damping pad main body 10 faces away from the base 41 of the compressor, and when the compressor is installed, the vibration damping pad main body 10 is located between the base 41 of the compressor and the inner wall of a case of refrigeration equipment, so that the base 41 of the compressor is not directly connected with the inner wall of the case of the refrigeration equipment. The mounting hole 21 is coaxially disposed with the damping pad body 10, and when the damping pad body is mounted, a connecting member 42 may penetrate through the mounting hole 21, so that the base 41 of the compressor may be connected to a refrigeration device through the connecting member 42.
Convex rib 30, convex rib 30 is cyclic annular, the quantity of convex rib 30 is a plurality of, and encircles in proper order and locate the first surface 11 of damping pad main part 10, a plurality of convex rib 30 with the coaxial setting of mounting hole 21. The mounting hole 21 is located the middle part of damping pad main part 10, it is a plurality of protruding muscle 30 encircles and locates the periphery of mounting hole 21 is a plurality of protruding muscle 30 by the center of first surface encircles in proper order to the peripheral direction of damping pad main part and establishes to form multilayer buffer structure. A plurality of ribs 30 may be disposed adjacent to each other to form a cushioning layer.
In an embodiment, a plurality of the ribs 30 are arranged at intervals, a buffer slot 31 is formed between adjacent ribs 30, and the buffer slot 31 forms a space for the deformation of the ribs 30. The number of the ribs 30 may be determined according to the overall diameter of the vibration-damping pad body 10. When the rib 30 is acted by the compressor, the rib 30 has a space bent in the longitudinal direction, so that the rib 30 can have the effect of longitudinal vibration isolation. Adjacent protruding muscle 30 can play the effect of mutual support between the messenger adjacent have the effect of mutual restriction deformation range between the protruding muscle 30, and then avoid producing the problem that too big deformation leads to the transverse vibration isolation effect to weaken between the adjacent protruding muscle 30. Optionally, the height of the rib 30 is not less than 1mm and not more than 2mm. The height of the rib 30 is the thickness of the rib 30 in the direction from the second surface 12 to the first surface 11 of the damping pad body 10.
Optionally, the number of the ribs 30 is not less than 3, the distance between adjacent ribs 30 may be equal, or the distance between adjacent ribs 30 may be adjusted according to the position of the rib 30. Optionally, the distance between adjacent ribs 30 is not less than 1mm, and not more than 2mm. The distance between adjacent ribs 30 is the width of the buffer groove 31 formed by the adjacent ribs 30. When the distance between the adjacent convex ribs 30 is greater than 2mm, the convex ribs 30 are easy to bend, the deformation range of the convex ribs 30 is large, and the transverse displacement range of the compressor is enlarged; when the distance between the adjacent ribs 30 is less than 1mm, the ribs 30 are not easily deformed, so that the transverse vibration isolation effect of the ribs 30 is weakened. When the height of the rib 30 is between 1mm and 2mm, the width of the buffer groove 31 is between 1mm and 2mm, so that the rib 30 cannot generate excessive deformation in the height direction, and the longitudinal vibration isolation effect of the rib 30 is further improved.
The plurality of ribs 30 form a buffer layer on the first surface 11 of the vibration damping pad main body 10, the buffer layer is attached to the base 41 of the compressor in the use state of the vibration damping pad main body 10, and when the compressor runs, the buffer layer formed by the ribs 30 can buffer the transverse vibration generated by the compressor, so that the transverse vibration transmitted to the refrigeration equipment is reduced.
The buffer layer formed by the convex ribs can reduce the transverse rigidity of the first surface of the vibration damping pad, so that the vibration isolation effect of the first surface of the vibration damping pad on the transverse vibration generated by the compressor is relatively improved, and the vibration damping pad main body below the convex ribs is further matched, so that the transverse vibration isolation effect is further enhanced. Because the convex rib 30 is arranged on the first surface 11 of the damping pad main body 10, most of the transverse vibration generated by the compressor is buffered by the convex rib 30, and the residual transverse acting force is further buffered under the action of the damping pad main body 10, so that the acting force transmitted from the damping pad main body 10 to the refrigeration equipment is further reduced. The damping pad body 10 can support the convex rib 30, so that the deformation range of the convex rib 30 generated when the convex rib 30 is subjected to the transverse vibration of the compressor is limited, and further the damage caused by the excessive deformation of the convex rib 30 is avoided.
The compressor is connected through connecting piece 42 with refrigeration plant to produce limiting displacement to the base 41 of compressor, the horizontal effort that the compressor operation produced can by protruding muscle 30 buffering reduces, is annular protruding muscle 30 can be followed each direction and cushioned lateral vibration, makes the whole atress of damping pad main part 10 is even relatively, is difficult to produce local atress and concentrates, and then makes damping pad main part 10 can keep predetermined form. When the compressor generates transverse vibration, each of the ribs 30 is of an annular structure as a whole, and the ribs 30 and the mounting holes 21 are coaxially arranged, so that the transverse vibration isolation has no specific directivity, and the acting force acting on the vibration damping pad main body 10 from all directions can be relatively uniform, so that the vibration damping pad main body 10 can further buffer the acting force from all angles, the acting force transmitted to the refrigeration equipment is further reduced, and the problem of force concentration in individual directions is not easy to occur.
When the compressor runs, the convex ribs 30 form a buffer layer on the first surface 11 of the vibration damping pad main body 10, the convex ribs protruding from the first surface have smaller longitudinal rigidity, and the buffer layer can buffer acting force along the axial direction of the vibration damping pad main body 10, so that a longitudinal vibration isolation effect is achieved. Through buffering longitudinal vibration, can reduce the produced longitudinal vibration effort of compressor, amplitude along with longitudinal vibration reduces, amplitude when making compressor lateral vibration also can reduce in step, and then can further reduce lateral vibration's effort, cooperation through longitudinal vibration damping and lateral vibration damping, promote damping efficiency, reduce the effort that transmits damping pad main part 10, under further damping and the cooperation of damping pad main part 10, make the effort that acts on refrigeration plant further reduce, and then reduce the noise that produces during the compressor operation, improve the operating stability of compressor.
The damping pad may be made of rubber, and the damping pad body 10 and the rib 30 are integrally disposed. Because protruding muscle 30 is only located the first surface 11 of damping pad main part 10, damping pad main part 10 plays the supporting role to protruding muscle 30, and the deformation of the relative protruding muscle 30 of deformation of damping pad main part 10 is littleer, the damping pad can further cushion the lateral deformation that protruding muscle 30 produced.

The clamping portion 20 forms a protruding structure outside the first surface 11 of the damping pad body 10 to match with a base 41 of the compressor. When the compressor is installed, a through hole is formed in the base 41 of the compressor, and the clamping portion 20 penetrates through the through hole of the base 41 of the compressor, so that the clamping portion 20 limits the base 41 of the compressor to move along the radial direction of the vibration damping pad main body 10. Connecting piece 42 of compressor runs through mounting hole 21, joint portion 20 encloses and locates the periphery of connecting piece 42, joint portion 20 can be used for blockking connecting piece 42 direct with the base 41 contact of compressor, and then avoid the vibration of compressor directly to transmit on the connecting piece 42, avoid producing vibration noise.
In order to promote the effect of horizontal damping, joint portion 20 is cylindric, optionally, joint portion 20 with the coaxial setting of mounting hole 21, so that the connecting piece 42 of compressor is right the produced effort of joint portion 20 can the homodisperse be in on the joint portion 20, the buffering effect on each side on the joint portion 20 is balanced relatively. The transverse vibration transmitted to the convex rib 30 from the connecting piece 42 and the clamping part 20 is relatively balanced, so that the transverse vibration isolation of the vibration damping pad has no directivity, and the vibration isolation performance is better.
Optionally, one end of the clamping portion 20, which is away from the first surface 11 of the damping pad main body 10, is provided with a limiting portion 22, and the limiting portion 22 is disposed on the periphery of the clamping portion 20.
