Abstract

The utility model discloses a rubber shock pad component special for a machine core of a freezer compressor. The rubber shock pad component special for the machine core of the freezer compressor comprises a cake-shaped shock pad body. A cylindrical shock pad plunger is arranged above the shock pad body in a coaxial mode. Threads are arranged on the outer periphery of the shock pad plunger from top to bottom. A sucking disc cavity is arranged in the lower end of the shock pad body. An inner bore is formed along the central axis of the shock pad body and the shock pad plunger in a penetrating mode. The rubber shock pad component special for the machine core of the freezer compressor has the advantages of being reasonable in structure, convenient to install, good in damping effect and noise reduction effect, strong in abrasion resistance, long in service life, and capable of being widely applied to machine cores of freezer compressors.

Description

Be exclusively used in the rubber shock-absorbing pad assembly of freezer compressor movement

Technical field

The utility model relates to the refrigerator accessory, is specifically related to rubber shock-absorbing mat structure and material that a kind of freezer compressor movement uses.

Background technique

Noise and level of vibration belong to one of key index of refrigerator, the beam of freezer compressor movement is contained on the damping spring of compressor movement bottom, the vibrations that cause in operation process to eliminate compressor, thereby play vibration damping and vibration isolation and reduce the effect of noise, the design of vibration insulating system whether rational relation to vibrations and the noise level of whole refrigerator.Suitable vibration-absorbing pad structure can effectively suppress the vibrations in compressor, and reduces vibrations and the noise of whole refrigerator system.On market, there are the shortcomings such as assembling is complicated, rigidity is higher and damping property is poor, and noise is large, and cost of production is high, not wear-resisting in existing freezer compressor movement beam.

Summary of the invention

Technical problem to be solved in the utility model is the defective that overcomes prior art, provide a kind of rational in infrastructure, assembling is simple, damping noise reduction is effective, wear resistance is strong, cost is low, the rubber shock-absorbing pad assembly of long service life.

For solving the problems of the technologies described above, the rubber shock-absorbing pad assembly that is exclusively used in the freezer compressor movement of the present utility model, the beam body that comprises patty, be coaxially arranged with columniform beam plunger above described beam body, be provided with screw thread on the excircle of beam plunger from top to bottom, the lower end of beam body is provided with the sucker chamber.

After adopting technique scheme, the utility model is connected with metal damping spring on refrigerator by the screw thread that is arranged on the beam plunger, and the sucker chamber is connected with compressor case; Because screw thread and metal damping spring closely cooperate, thereby reduce friction in work, the vibrations that more effective decomposing metal damping spring transmission simultaneously comes.In working procedure, sucker chamber and compressor case bottom fit tightly, and increase adhesive force, to play better absorption fixation.The Rubber shock-absorbing pad modular construction that is exclusively used in the freezer compressor movement of the present utility model is simple, can replace existing metal positioning support, reduces assembly process, enhances productivity.The utility model in use, damping noise reduction is effective, wear resistance is strong, cost is low, long service life.

Further, the rubber shock-absorbing pad assembly that is exclusively used in the freezer compressor movement of the present utility model, its medial axis along beam body and beam plunger connects and is provided with endoporus.

After adopting technique scheme, the rubber shock-absorbing pad assembly that is exclusively used in the freezer compressor movement of the present utility model can further add strong adaptability, in compressor outer casing structure complexity, bottom and the rough situation of beam surface of contact, the utility model still can be good at being complementary with related accessory, plays the effect of damping noise reduction.

Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

Embodiment one

By Fig. 1, Fig. 2, Fig. 3 as seen, the present embodiment comprises the beam body 1 of patty, be coaxially arranged with columniform beam plunger 2 above described beam body 1, be provided with screw thread 3 on the excircle of beam plunger 2 from top to bottom, the lower end of beam body 1 is provided with sucker chamber 4.

The rubber shock-absorbing pad assembly that is exclusively used in the freezer compressor movement of the present utility model is made with elastic material, on structure, requires to possess certain deformability, and deformation index can reach requirement in 2% to 20% scope.Meeting under the prerequisite of above-mentioned deformation index, the utility model possesses suitable rigidity, possesses simultaneously buffer capacity preferably.

Under the prerequisite that meets the said structure requirement, the utility model preferably uses rubber material to make, for example can use the HNBR elastomeric compound by formula adjust the sulfuration after become have certain rigidity, flexible shock reducing structure, make it in damping, also have more excellent oil resistant, wear-resisting, high-low temperature resistant, heat oxygen aging resistance, anti-ozone, resistant to chemical media, good dynamic performance etc.

Sucker chamber 4 fingers are built in the spherical cavity of beam body 1 lower end, its bottom surface overlaps with beam body 1 bottom surface, sphere is arranged on beam body 1 inside, sucker chamber 4 bottom surface diameters and beam body 1 bottom surface diameter ratio are 0.6～0.9:1, thereby guarantee between beam body 1 and compressor case, good contacting to be arranged.In the utility model when work,, adsorption effect can be improved in sucker chamber 4, thus improved between the utility model and associated components in conjunction with soundness, its cavity space possesses certain buffer function in addition, can reduce vibrations.

Product is in the assembling using process, closely cooperating and the strong adhesive of sucker chamber, bottom 4 and outer casing base of screw thread 3 by the top and damping spring mouth, from usability, the vibrations that produce in the time of movement work can better being turned round are effectively transmitted, absorb, are degraded, and reduce the friction between metal and beam assembly, improve working life, from fit on, structure is comparatively simple, and assembling is enhanced productivity than being easier to.

Embodiment two

Refrigerator kind on market is more, and part freezer compressor shell mechanism complexity, bottom and beam surface of contact are uneven, in such cases, require the rubber shock-absorbing pad assembly to possess better structure adaptability.

As Fig. 4, Fig. 5, Fig. 6 as seen, on embodiment one basis, for this kind situation, the present embodiment further is optimized design.

The present embodiment plate comprises the beam body 1 of patty, be coaxially arranged with columniform beam plunger 2 above described beam body 1, it is characterized in that: be provided with screw thread 3 on the excircle of beam plunger 2 from top to bottom, the lower end of beam body 1 is provided with sucker chamber 4, connects along the medial axis of beam body 1 and beam plunger 2 and is provided with endoporus 5.

After adopting technique scheme, the utility model can adapt to the various labyrinths of matching parts better, still possesses good damping noise reduction effect.
