Abstract
The invention discloses a resonance-resisting multi-step spring damping device which comprises a plurality of springs with different ring diameters, wherein the springs are arranged in the mode that the ring diameters become larger or smaller gradually to form a multi-step structure, the lengths of the springs become larger or smaller gradually along with the formed multi-step structure, the diameters of steel wires of the springs become larger or smaller along with the formed multi-step structure, and the multi-step structure is formed by linear arrangement of the springs or sleeved connection of the springs. The device aims to disperse points with inherent frequencies and weaken resonance by means of the multiple springs (different inherent frequencies are formed by combination of different springs and an object) which form the multi-step structure, and then the purpose to pass resonance areas quickly and steadily is achieved.
Description
Technical field
The present invention relates to vibrating machine technical field, more specifically say a kind of anti-resonance vibration cascade spring vibration damping device.
Background technique
Vibrating machine has two large problems: 1. " vibration " effectively; 2. quick smoothly cross " resonance region ".
For example: vibrating sieve be capital equipment in crushing production line this.Vibrating sieve is when crushing operation, and " exciting " effect due to eccentric shaft, in work done campaign, must be accompanied by the larger vibration of equipment, especially crosses " resonance region " this technical barrier.For the machinery in running, " resonance " is undoubtedly to self causing serious harm.So " resonance " phenomenon of vibrating mechanical equipment is the difficult problem that mechanical engineering technicians must reckon with in design, manufacture and installation process, it is also the major project of tackling key problem.
At present, in prior art, vibrating sieve is crossed to " resonance region " problem and also there is no effective method, conventionally be all to adopt to allow unrestrained freedom it, such result is: at vibrating sieve, start or stop in process (generally in 80～120r/min scope) while crossing resonance region, cause that whole equipment significantly rocks, the component relevant to motion such as vee belt, connecting bolt and even bearing are all produced greatly and impacted, have a strong impact on its life-span.
Summary of the invention
It is above not enough that the object of the invention 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 object, the present invention is achieved by the following technical solutions: a kind of anti-resonance vibration cascade spring vibration damping device, it is characterized in that, comprise many circle footpath different springs, these springs by Qi Quan 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 chap or attenuate gradually with the stepped construction of its formation.
As preferably, the formation of stepped construction is arranged and is formed by these spring yi word pattern.
As preferably, the formation of stepped construction is by being socketed to form inside and outside these springs.
Of the present invention opening one's minds is: by mechanics principle, any object (refers to vibrating mechanical equipment here, there is the natural frequency of oneself down together), when external force causes this object to produce vibration frequency to reach near 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, resonance phenomenon concentrates on the natural frequency point region of this vibrating mechanical equipment, and it is larger that vibration more approaches natural frequency " resonance " amplitude.The numerical value of object natural frequency is relevant to the material of object, volume shape and spring etc.
The present invention imagines a plurality of spring assemblies (natural frequencys that different springs is synthetic different from group of objects) that use formation " hierarchic structure formula ", to disperse the concentration degree of natural frequency, what is said or talked aboutization " resonance " phenomenon, reaches fast, crosses reposefully the object of resonance region.
Core technology of the present invention 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 invention is: cross fast, reposefully " resonance region ".
Except above significantly function, the present invention also has following beneficial effect:
1. spring stress is balanced, and extend working life;
2. because vibrating steadily, also extend 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 vibrating machine technical field.
