Abstract
The invention opened an equilibrator that was used to be fan equipment. And it includes a rotatable part, which has a capacitance space that adapts to contain the equilibrator. And the space is depending on two borders at least. The equilibrator include: a noumenon; a springy part locating the noumenon. When the equilibrator is placed in the capacitance space, the noumenon and the springy part are leaned to at least two side walls separately. The invention adapt to put the equilibrator into the capacitance space, and so as to reach the purpose of keeping running balance.
Description
Technical field
The present invention system particularly is applied to the Equilibrator that rotation is tended to be steady about a kind of Equilibrator.
Background technique
Along with improving constantly of fan assembly performance, the mechanism of fan assembly is accurate day by day, and when fan assembly rotates, the vibration of generation and noise all will become the problem that must overcome.
When fan assembly rotates, if the physics centroid position of its rotor and the rotating shaft center of inertia not simultaneously, will cause the rotor rotation imbalance, thereby generation centrifugal force, and act on rotary shaft rack and form vibration.And this vibration also will be sent to the mechanical structure each several part, produce noise.
The physics centroid position of the rotor reason different with the center of inertia of rotating shaft is roughly as follows: (1) flabellum is inhomogeneous with the perpendicularity and the concentricity that coat the flabellum shell; (2) stability of plastics flabellum moulding is not good, and for example, the leaf weight uniformity of flabellum is not good, each interlobate figure tolerance is big; (3) in flabellum and shell when assembling,, improper assembling causes deformable blade or compression distance inhomogeneous; (4) the shell out of roughness is not good; (5) shell is in uneven thickness; (6) after rotor magnet was packed shell into, the seam of its binding end was not good etc.
Owing to above-mentioned tolerance, abrasion, structure motion distortion or the like reason, desirable rotary balance will be difficult to reach; So, can be according to certain reconciliation of inventory standard, the balancing rotor control of machinery is reached to following balancing mass that can allow of corresponding rotating speed, and further reduce to vibrate the power consumption penalty that causes, and meet examination and test of products standard and be able to the lifting device life-span.
In order to keep the rotary balance of fan assembly, the equilibrium structure of conventional fan device is summarized as follows:
With reference to figure 1, one fan assembly, comprise a rotation section 1, wherein this rotation section 1 has a containing space 2; One balancing patch 3 is to be located in this containing space 2.Wherein, the material of this balancing patch 3 is a copper, and is to utilize a material with stickiness, and for example AB glue or two sided plaster are fixed in this containing space 2, in the hope of reaching the purpose that keeps the fan rotary balance.If use AB glue, then according to gel time, need balance to place after the gluing approximately one hour, just generally low-rotate speed rotates, and to avoid this balancing patch 3 under no preferable fixing situation, drops out when fan running.
Remove said structure, also a balance soil 4 can be fixed on the madial wall of this rotation section 1, or use the mode of above-mentioned balancing patch 3 and balance soil 4 simultaneously, be located in the identical or different containing space, to reach the purpose that keeps rotary balance.
Yet, the viscosity of this balance soil 4 and humidity instability, when fan running, easily produce fixing not good or problem such as fall out, so generally normal fix this balance soil 4 after, place again more than two hours, in the hope of reaching preferable quality.
Adopt above-mentioned known techniques, not only the built-up time of fan component is long, and manufacturing efficiency is low, and has the not good shortcoming of quality.
Summary of the invention
The objective of the invention is to, a kind of Equilibrator that is used for a fan assembly is provided, wherein this fan assembly comprises a rotation section, and this rotation section has a containing space, fit and can hold this Equilibrator, and this containing space system is defined by at least two limit walls; This Equilibrator comprises: a body; And a spring section, be located on this body; Wherein when this Equilibrator was contained in this containing space, this body and this spring section are suitable to be resisted against respectively on this two limits wall at least.
The design of the Equilibrator of this creation, its structure is simple relatively, it is very easy to make, and the formality enter this containing space of planting is very easy, make whole fan assembly assembling, and assembling after balance adjust efficient and significantly promote; In addition, when being sticked in this containing space, also have enough stabilitys, and adjusted its position at any time, be not subjected to the influence of the fixed-site of gluing or clay,, when fan assembly has the demand of row fine setting balance, still have suitable elasticity again even if after a period of time.
Description of drawings
Fig. 1 is in the existing preceding technology, comprises the fan assembly structural representation of Equilibrator;
Fig. 2 is a balance device structure schematic representation of the present invention.
Primary clustering symbol description among the figure:
1 rotation section, 2 containing spaces, 3 balancing patches, 4 balance soil, 5 bodies, 501 spring section

Embodiment
A kind of steady device 10 that is used for fan assembly of the present invention of being shown in Figure 2 comprises a spring section 501 of being located on the body 5; And be symmetricly set in a opening 6 on this body 5.Wherein, this opening 6 is to be defined jointly by two relative first limit walls 502 and two 503 on the relative second limit walls.
The preferably, the strip of these body 5 cording rectangles, and the material of its use is an elastic material, the blade material of the stable voltinism of tool, enough elasticity and hardness ratio fan assembly is hard, for example stainless steel material.This body 5 and spring section 501 are an integrally formed metal sheet, and this spring section 501 is from these first limit walls 502 one of them, and from a direction away from this body 5, turnover is extended.
This containing space 2 is defined by at least two limit walls, when this Equilibrator 10 is arranged in the containing space 2 of this rotation section 1, produce elastic-restoring force behind these spring section 501 pressurizeds on the Equilibrator 10, and with the body 5 and the spring section 501 of this Equilibrator 10, firmly be resisted against respectively at least two limit walls of this containing space 2, and reach the purpose of in fan assembly, fixing this Equilibrator 10.
According to the requirement of stock size fan assembly, the elastic-restoring force power that this spring section 501 is out of shape is no more than 2.0 kilograms, so can avoid causing rotation section 1 distortion of fan assembly; The strength of this spring section 501 in this containing space 2 is set, then preferably is no more than 1.0 kilograms, to promote better operability; Self weight distribution of this Equilibrator 10 also reaches symmetrical balance as far as possible so that in the less containing space, be easier to adjust, and the better counterbalance effect of performance.
In sum, the Equilibrator 10 of this creation is very easily in this containing space 2 of this rotation section 1 of direct insertion, to adjust the rotary balance of fan assembly.Only the foregoing description only is the principle and the effect thereof of this creation of illustrative, but not is used to limit this creation.Any ripe personage in this creation skill all can be under the situation of the know-why of this creation and spirit, and the foregoing description is made amendment and changed.For example, changing the material of this Equilibrator and forming mode, change defines the limit wall quantity of containing space and shape, and changes the dimension scale etc. of body and spring section.Claim is listed as described later for the rights protection scope of this creation.
