Description
Technical field
The utility model relates to a kind of rubber rubber cushion, relates in particular to a kind of anti-vibration pad for refrigerator compressor.
Background technique
During compressor operation, due to reasons such as the running of compressor internal mechanical part, mating parts friction, gas shocks, can cause compressor noise and vibration in various degree.
Under the long-term impact in noise, easily make people's lather, serious more can affecting is healthy.
For freezer compressor, its Environmental Conditions be mostly people live indoor, for noise, have relatively high expectations, when especially night is quiet, for the noise vibration of compressor, for the noise of compressor, higher needs have been proposed.
Fig. 2 is the anti-vibration pad for refrigerator compressor of prior art, and its structure is the central cylindrical structure that offers through hole, and material is rubber, and during use, quakeproof rubber pad is sleeved on the supporting foot of compressor bottom.Due to the restriction of structural type, this quakeproof rubber pad, damping effect is not desirable especially.Reason is, its damping effect of the quakeproof rubber pad of this structure only relies on the elastic strain of rubber cushion material itself, its compression or tensile deformation amount are relatively little,, quakeproof rubber pad is in the course of the work from compressed distortion until " springing stroke " recovered deformed state is shorter, thereby the buffer capacity of the vibrations that freezer compressor is produced is limited, damping effect is not desirable especially.
Model utility content
The purpose of this utility model is, provide that a kind of compression or tensile deformation amount are large, the freezer compressor rubber cushion of good damping effect, effectively to cushion the vibrations that produced in freezer compressor working procedure, and then reduce in compressor operating process because of the noise of vibratory output due to excessive.
The utility model to achieve these goals technical issues that need to address is, by improving the internal cavity structures of rubber cushion and the matching relationship between rubber cushion and compressor supporting foot for freezer compressor, to obtain the technical problem of damping effect preferably.
The utility model is that the technical solution that solves the problems of the technologies described above employing is, a kind of anti-vibration pad for refrigerator compressor, for upper, middle and lower segment central authorities offer respectively the cylindrical structural of through hole, epimere is that upper occlusion part, stage casing are quakeproof rubber pad supporting portion for coordinating neck, hypomere, it is characterized in that, the top of described quakeproof rubber pad supporting portion inwall arranges U-shaped bradyseism groove.
The technique effect that technique scheme is directly brought is, by the top at quakeproof rubber pad supporting portion inwall, be provided with U-shaped bradyseism groove, can effectively reduce " rigidity " of whole quakeproof rubber pad, in the situation that be subject to the power in onesize Vertical direction, the deformation quantity of compression/stretching that quakeproof rubber pad produces will increase.That is to say, the onesize vibrations that produce in running for freezer compressor, its cushioning effect is better;
On the other hand, the through hole that its central authorities of the quakeproof rubber pad of prior art offer is cylindrical, and its inwall everywhere diameter all equates; At freezer compressor, in running, produce in the vibrations process in Vertical direction, compressor supporting foot will vertically with in other each side surface direction produce respectively a certain amount of motion or movement tendency in quakeproof rubber pad interior bone, and this vibrations will drive a certain amount of air-flow to shake and produce a certain amount of noise.
On the top of quakeproof rubber pad supporting portion inwall, offer U-shaped bradyseism groove, because the diameter of this U-shaped bradyseism groove is larger than the diameter of quakeproof rubber pad interior bone, " cavity area " forming between above-mentioned U-shaped bradyseism groove region and compressor supporting foot like this;
Because compressor supporting foot produces in the vertical direction a certain amount of motion or movement tendency in quakeproof rubber pad interior bone, this vibrations will drive a certain amount of flow perturbation, and then produce a certain amount of noise.In this case, above-mentioned " cavity area " will play simultaneously buffer gas flow and then produce the effect of " noises elimination ", further reduce because of in compressor operating because of the noise due to shaking;
Further analyze, when compressor supporting foot in quakeproof rubber pad interior bone along producing a certain amount of moving or movement tendency in other each side surface direction, for a certain amount of motion or the movement tendency that produce in other each side surface direction, and form thus noise.Above-mentioned owing to existing " cavity area ", should " cavity area " absorbs the vibrations in each side surface direction, causes the decay of above-mentioned shock momentum, on the one hand, can cross the noise alleviating because of due to the vibrations of compressor supporting foot; On the other hand, also will the shock momentum being delivered in the environmental ambient air outside himself by quakeproof rubber pad be reduced, that is, reduced the noise due to himself shaking.
As preferably, above-mentioned U-shaped bradyseism groove is at least more than one.
The technique effect that above-mentioned optimal technical scheme is directly brought, consistent with aforesaid technique effect, just its technique effect is quantitatively accumulated and increases.
Certainly, the concrete quantity that U-shaped bradyseism groove arranges, need to be according to the size of power in the required Vertical direction of bearing of whole quakeproof rubber pad, the aspects such as the material of quakeproof rubber pad, processing cost and difficulty of processing carry out determining after overall balance.
Further preferably, above-mentioned quakeproof rubber pad interior bone is up-thin-low-thick shoulder hole near the position of bottom, quakeproof rubber pad supporting portion.
The technique effect that above-mentioned optimal technical scheme is directly brought is, quakeproof rubber pad supporting portion interior bone is up-thin-low-thick shoulder hole near the position of its bottom, this can further reduce the area of contact on quakeproof rubber pad and ground, further reduce " rigidity " of whole quakeproof rubber pad, in the situation that be subject to the power in onesize Vertical direction, the deformation quantity of compression/stretching that quakeproof rubber pad produces will be larger.That is to say, the onesize vibrations that produce in running for freezer compressor, its cushioning effect will be better.
Further preferably, the top of the upper occlusion part of above-mentioned quakeproof rubber pad is also provided with chamfering.
The technique effect that above-mentioned optimal technical scheme is directly brought is that on the one hand, the installation of quakeproof rubber pad is more convenient; On the other hand, the setting up of chamfering, for effective alleviation or alleviate that quakeproof rubber pad bears fatigue damage due to stressed that compressor own wt and vibrations bring for a long time and because of aging due to being heated for a long time, and then the factor such as crushed has positive meaning.That is, setting up of chamfering, is conducive to extend the working life of quakeproof rubber pad.
In sum, freezer compressor rubber cushion of the present utility model, on the basis of existing technology by the improvement on the matching relationship dependency structure between simple internal cavity structures and rubber cushion and compressor supporting foot, increased significantly quakeproof rubber pad shockproof and anti-acoustic capability, extended the working life of quakeproof rubber pad and reduced the fitting operation difficulty of quakeproof rubber pad.Thereby freezer compressor of the present utility model with respect to prior art, has useful technique effect and progress with rubber cushion.
