Description
Technical field
The present invention relates to the washing machine technical field, relate in particular to a kind of rotary drum washing machine damping assembly.
Background technology
Washing machine and similar machinery are in the course of the work, unbalance loading and centrifugal action due to washing articles, keep away unavoidably and can produce resonance, will make the machinery generation beat and can't work if can not eliminate well resonance, so in washing machine, damping assembly must be installed.
Be used at present the damping assembly that rotary drum washing machine uses both at home and abroad, roughly be divided into two kinds, 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 is to produce friction by a nylon slide block or the suspension rod of other rubber and centre to play the absorbing effect, the damping assembly of this structure is simple in structure, 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, will cause damping assembly to lose efficacy fast, thus this kind structure must control frictional force can not be excessive, so just limited this kind damping assembly and can only use on the washing machine of low capacity.the damping assembly of frictional damping and air damping and use is to form by a plastic sleeve and a rubber piston, produce damping by motion generation friction and air venting between piston and nylon jacket and come absorbing, this structure is because compressed exhaust and the meeting of suction of air produce noise, therefore the damping assembly noise of this kind structure is larger, and this kind structure can not reach higher desirable absorbing performance to aeroseal is bad, therefore this kind structure is applied in above medium-sized impeller automatic washing machine at present always, also there is no ideal damping assembly as large capacity rotary drum washing machine always, because the increasing along with the washing of drum type washing machine capacity, require the absorbing performance of damping assembly also will strengthen, the coefficient of friction of frictional damping is constant basically, can not improve along with the increase of amplitude damping property, so the effect that the damping assembly of frictional damping and air damping and use uses on large capacity rotary drum washing machine is also bad.
Summary of the invention
Technical problem to be solved by this invention is: a kind of rotary drum washing machine damping assembly is provided, and its good damping result can improve along with the increase of amplitude effectiveness in vibration suppression, and the noise that produces 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, an end is provided with gooseneck bracket, the other end is provided with piston component, on described suspension rod, sealing is slidably fitted with sleeve, described sleeve is established Packed air chamber, described piston component is positioned at described air chamber and is slidably matched with described sleeve seal, described air chamber is divided into without the rod seal chamber and the rod seal chamber is arranged by described piston component, described suspension rod passes the described rod seal chamber of having, described piston component is provided with and produces air-damped pod apertures, described pod apertures is communicated with described without the rod seal chamber with the rod seal chamber is arranged, described have in the 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 of being made by rubber, the inwall of described sealing ring and described sleeve offset and sealed sliding movingly.
As a kind of preferred version, the surface that the inwall of described sealing ring and described sleeve offsets is coated with polytetrafluoroethylene floor.
As a kind of preferred version, slide on described suspension rod and be provided with sealing ring pop-up and sealing ring subiculum, described sealing ring cramping is 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 the 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, the end near described gooseneck bracket on described sleeve is provided with for the groove of storing lubricant grease, and described suspension rod passes described groove.
owing to having adopted 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 suspended on suspension rod, under the staving action of gravitation, the Compress Spring compression, piston component is suspended from air chamber, piston has reciprocating space, during washing machine work, the staving vibration, thereby piston component is done with respect to sleeve to reciprocatingly slide, because air chamber is airtight, and piston component is provided with pod apertures, when therefore piston component moves with respect to sleeve, can Repeated Compression without the rod seal chamber with the rod seal chamber is arranged, thereby formation air damping, play the effect of absorbing vibration damping, the present invention has following several advantage:
(1) do not need frictional damping, this structure utilizes air damping can reach the effectiveness in vibration suppression of washing machine demand fully, piston component only need keep getting final product with the sealing of sleeve, although piston component unavoidably can produce friction with sleeve, but reduce the frictional force between piston component and sleeve during design as far as possible, make this structure durable in use.
(2) air chamber is all-sealed structure; inner air produces air damping by the pod apertures on piston component, air and isolate from outer air in air chamber, thereby the reduction noise that produces in the time of can using; and can prevent that extraneous dust from entering in air chamber, play the effect of protection piston component.
(3) damping property is along with different amplitudes or frequency are regulated automatically, because air chamber seals, when larger the or frequency of amplitude is higher, the damping force of this structure generation also can be along with automatic increasing, so just can better meet the self-adaptive damping requirement, reach optimal effectiveness in vibration suppression, the amplitude of jumbo washing machine is larger, so this structure can satisfy the vibration damping requirement of high-capacity washing machine.
The surface that offsets due to the inwall of described sealing ring and described sleeve is coated with polytetrafluoroethylene floor, can reduce the frictional force between sealing ring and sleeve, and guarantees the durability that sealing ring uses.
Because the end near described gooseneck bracket on described sleeve is provided with for the groove of storing lubricant grease, described suspension rod passes described groove, fills lubricant grease in groove, improves the sealing between suspension rod and sleeve, the frictional force between reduction both.
