Abstract
The utility model discloses an anti-resonance stepped-type spring oscillation damping device which comprises a plurality of springs with different ring diameters. The springs are arranged with the ring diameters gradually increased or gradually decreased to form a stepped-type structure. The lengths of the springs are gradually increased or gradually decreased along the formed stepped-type structure, the diameters of steel wires of the springs are gradually thickened or thinned along the formed stepped-type structure, and the stepped-type structure is formed by arranging the springs in a straight-line mode or connecting the springs in an inside-outside sleeve mode. The anti-resonance stepped-type spring oscillation damping device imagines that a plurality of spring combinations (different springs are combined with objects to form different inherent frequencies) for forming the stepped-type structure to disperse points of the inherent frequencies, desalt resonance and achieve a purpose of rapidly and stably passing through a resonance area.
Description
Technical field
The utility model relates to the vibrating machine technical field, more specifically says a kind of anti-resonance vibration cascade spring vibration damping device.
Background technique
Vibrating machine has two large problems: 1. effectively " vibration "; 2. quick flat is crossed " resonance region " quietly.
For example: vibrating sieve be in the crushing production line capital equipment this.Vibrating sieve because " exciting " of eccentric shaft effect in the work done campaign, must be accompanied by the larger vibration of equipment, is especially crossed " resonance region " this technical barrier when crushing operation.For the machinery in the running, " resonance " is undoubtedly to self causing serious harm.So " resonance " phenomenon of vibrating mechanical equipment is the difficult problem that the mechanical engineering technicians must reckon with in design, manufacturing and installation process, it also is the major project of tackling key problem.
At present, in the prior art vibrating sieve is crossed " resonance region " problem and also do not have effective method, usually all be to adopt to allow unrestrained freedom it, such result is: start or stop in the process (generally in 80～120r/min scope) when crossing resonance region at vibrating sieve, cause that whole equipment significantly rocks, the component relevant with motion such as vee belt, connecting bolt and even bearing are all produced greatly impact, have a strong impact on its life-span.
The model utility content
It is above not enough that the utility model purpose is to overcome prior art, and a kind of simple in structure, reliable performance, economical and practical " anti-resonance vibration hierarchic structure formula resilient supporting unit " are provided.
In order to reach above purpose, the utility model is achieved through the following technical solutions: a kind of anti-resonance vibration cascade spring vibration damping device, it is characterized in that, comprise the many springs that circle footpath is different, these springs by its circle footpath gradually increasing or decreasing arrange and form stepped construction.
As preferably, the length of these springs is elongated or shorten gradually with the stepped construction of its formation.
As preferably, the steel wire diameter of these springs is gradually chap or attenuate with the stepped construction of its formation.
As preferably, the formation of stepped construction is arranged by these spring yi word patterns and is formed.
As preferably, the formation of stepped construction is by being socketed to form inside and outside these springs.
Of the present utility model opening one's minds is: press mechanics principle, any object (refers to vibrating mechanical equipment here, lower with) oneself natural frequency arranged, when external force causes this object to produce vibration frequency to reach near the natural frequency, vibration will several times ... tens times of ground amplify (vibration is unfailingly amplified by lecture in theory), physical phenomenon that Here it is " resonance ", it can cause very big destruction to vibrating mechanical equipment.
According to physics " resonance " principle, the natural frequency point zone that resonance phenomenon concentrates on this vibrating mechanical equipment vibrates more larger near natural frequency " resonance " amplitude.The numerical value of object natural frequency is relevant with the material of object, volume shape and spring etc.
The utility model imagination is used a plurality of spring assemblies (natural frequencys that different springs is synthetic different from group of objects) that form " hierarchic structure formula ", to disperse the concentration degree of natural frequency, what is said or talked aboutization " resonance " phenomenon reaches fast, crosses reposefully the purpose of resonance region.
Core technology of the present utility model is: use the spring assembly of hierarchic structure formula, and the natural frequency of desalting plant, thus reduce or elimination " resonance " drawback.
Remarkable function of the present utility model is: cross fast, reposefully " resonance region ".
Except above remarkable function, the utility model also has following beneficial effect:
1. spring stress is balanced, and prolong working life;
2. because vibrating steadily, also prolong the working life of vee belt and Jin Gu Luo Quan.
" anti-resonance vibration hierarchic structure formula resilient supporting unit " designs, and broken through the technical barrier of elimination vibrating sieve " resonance " in service drawback, is the large technological progress of one in the vibrating machine technical field.
