Description
Technical field
The present invention relates to washing machine technology field, particularly relate to a kind of rotary drum washing machine damping assembly.
Background technology
Washing machine and similar machinery are in the course of the work, due to unbalance loading and the centrifugal action of washing articles, keep away and unavoidably can produce resonance, machinery generation will be made to beat and cannot normally work if resonance can not be eliminated well, therefore damping assembly must be installed in washing machine.
The domestic and international damping assembly used for rotary drum washing machine, is roughly divided into two kinds at present, and a kind of is the pure frictional damping formula damping assembly of low capacity use in washing machine, and another is friction and air damping and uses damping assembly.Wherein pure frictional damping formula damping assembly produces friction by a nylon slide block or the suspension rod of other rubber and centre to play absorbing effect, the damping assembly structure of this structure is simple, cost is lower, but frictional force is more fixing, and the wearing and tearing between the larger material of frictional force also can be accelerated, damping assembly will be caused to lose efficacy fast, therefore this kind of structure must control frictional force can not be excessive, so just limit this kind of damping assembly and only can be used in above the washing machine of low capacity.Frictional damping and air damping and damping assembly be by a plastic sleeve and a rubber piston composition, produce damping by motion generation friction and air venting between piston and nylon jacket and carry out absorbing, this structure can produce noise due to the compressed exhaust of air and suction, therefore the damping assembly noise of this kind of structure is larger, and this kind of structure can not reach higher desirable absorbing performance to aeroseal is bad, therefore this kind of structure is applied in above medium-sized impeller automatic washing machine at present always, also there is no ideal damping assembly as Large Copacity rotary drum washing machine always, because along with the increasing of washing of drum type washing machine capacity, require that the absorbing performance of damping assembly also will strengthen, the coefficient of friction of frictional damping is constant substantially, damping property can not be improved along with the increase of amplitude, therefore frictional damping and air damping and the effect that uses on Large Copacity rotary drum washing machine of damping assembly and bad.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of rotary drum washing machine damping assembly, its good damping result, can improve effectiveness in vibration suppression along with the increase of amplitude, and the noise produced is little.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of rotary drum washing machine damping assembly, comprise suspension rod, on described suspension rod, one end is provided with gooseneck bracket, the other end is provided with piston component, on described suspension rod, sealing is slidably fitted with sleeve, Packed air chamber established by described sleeve, described piston component is positioned at described air chamber and is slidably matched with described sleeve seal, described air chamber is divided into without rod seal chamber by described piston component and has rod seal chamber, rod seal chamber is had described in described suspension rod passes, described piston component is provided with and produces air-damped pod apertures, described pod apertures be communicated with described without rod seal chamber with have rod seal chamber, described have in rod seal chamber be provided with Compress Spring, described Compress Spring is set on described suspension rod.
As a kind of preferred version, described piston component comprises the sealing ring be made up of rubber, and the inwall of described sealing ring and described sleeve offsets and seals and is slidably matched.
As a kind of preferred version, the Surface coating that the inwall of described sealing ring and described sleeve offsets has polytetrafluoroethylene floor.
As a kind of preferred version, described suspension rod slides and is provided with sealing ring pop-up and sealing ring subiculum, described sealing ring clamps between sealing ring pop-up and sealing ring subiculum, and described Compress Spring is installed between described sealing ring pop-up and described sleeve.
As a kind of preferred version, described piston component is slidably mounted on described suspension rod, and is provided with suspension rod sealing rubber pad between described suspension rod and piston component.
As a kind of preferred version, described suspension rod sealing rubber pad is between described sealing ring pop-up and described sealing ring subiculum.
As a kind of preferred version, described sleeve is provided with the groove for storing lubricant grease near one end of described gooseneck bracket, described suspension rod is through described groove.
Owing to have employed technique scheme, during use, the external box of microvave of gooseneck bracket and washing machine links together, the staving of washing machine internal is installed on sleeve, staving is made to be suspended on suspension rod, under the effect of staving gravity, Compress Spring compresses, piston component is made to be suspended from air chamber, piston has reciprocating space, during washing machine work, staving vibrates, thus piston component is reciprocatingly slided relative to sleeve, because air chamber is airtight, and piston component is provided with pod apertures, therefore when piston component moves relative to sleeve, meeting Repeated Compression is without rod seal chamber and have rod seal chamber, thus formation air damping, play the effect of absorbing vibration damping, the present invention has following several advantage:
(1) frictional damping is not needed, this structure utilizes air damping can reach the effectiveness in vibration suppression of washing machine demand completely, piston component only need keep the sealing with sleeve, although piston component inevitably produces with sleeve and rubs, but the frictional force reduced during design between piston component and sleeve, makes this structure durable in use as far as possible.
(2) air chamber is all-sealed structure; inner air produces air damping by the pod apertures on piston component, the air in air chamber and isolate from outer air, thus the reduction noise produced when can use; and can prevent external dust from entering in air chamber, play the effect of protection piston component.
(3) damping property regulates automatically along with different amplitudes or frequency, because air chamber is sealing, when amplitude is larger or frequency is higher, the damping force that this structure produces also can along with automatic increasing, so just can better meet self-adaptive damping requirement, reach optimal effectiveness in vibration suppression, the amplitude of jumbo washing machine is comparatively large, and therefore this structure can meet the damping requirements of high-capacity washing machine.
The Surface coating offseted due to the inwall of described sealing ring and described sleeve has polytetrafluoroethylene floor, can reduce the frictional force between sealing ring and sleeve, and ensure the durability that sealing ring uses.
Because the one end near described gooseneck bracket on described sleeve is provided with the groove for storing lubricant grease, described suspension rod, through described groove, fills lubricant grease in groove, improves the sealing between suspension rod and sleeve, reduces frictional force therebetween.
