A small quantity of low-viscosity liquid can be placed in the cylinder or ring cavity for compensating balance. It has no vibration and is high in balancing accuracy.
Description
The present invention is used for rotating machinery, is specially adapted to the dynamic balancer of middle and high fast rotating machinery.
At No. 69316 patent announcements of Russia a balancing technique, utilize the vibration of electromagnet generation metope, it is free movable to make in the liquid of bead in the toroidal cavity of rotation, thereby compensates the unbalanced force when rotating, and stop on the equilibrium position, so bead by locked with electromagnet on this position.In this technology, the motion of bead does not reach the balance quality that dynamic balancing needs, because need overcoming the resistance in the viscous liquid, the motion of bead weakened its receptance, in the vibrative moment of electromagnet itself is vibrated more with regard to unbalanced machinery, thereby destroy the tram of bead balance.The balancing technique of another hollow shaft is disclosed in No. 406000 patents of the U.S., in being balanced the axle of part, put a stuffing box gland exactly, a toroidal cavity is arranged in the cover, balance bead and hot set adhesive are housed in this toroidal cavity, when rotating speed surpasses resonance velocity, bead in the toroidal cavity is regulated non-equilibrium state with regard to the mobile position, heating pad pipe or this type of heating arrangement by the motion of control bead becomes adhesive into solid-state glue under the thermal change condition at last, so bead is locked on the position after the adjusting, this technology does not reach the needed balance quality of dynamic balancing equally, because the friction that the liquid viscose agent produces makes bead can not be in the tram, very difficult when needs are readjusted bead, very inconvenient in the use.Also has an european patent application (notification number 0434270A2), application number 90313349.4, the technology of disk file transient equiliblium is disclosed in this patent application, exactly with being installed in rotatingshaft on the balance track in the concentric circular groove, many mobilizable beads are arranged, can carry out transient equiliblium to the disk file, just turn at bead after the starting operation on the initial angle of balance, when rotating speed surpasses resonance velocity, because centrifugal force increases, at this moment will force bead to release this balance track, back down the elasticity baffler that the interior side of circular groove slightly is projection, and the interior location that enters in this groove promptly stops on the track, and this balance track communicates with stopping between the track.Because the resilient force that bending had of circular groove, bead is clamped here fixing.In this technology, after centrifugal force increases, bead wants to enter from the balance track when stopping track, need overcome the baffler resistance in the baffle area, and before rotating speed reaches maximum constant speed, bead is by the steel body elasticity baffler clamping of baffle area internal projection, and can not be on circular path motion and balance again.That is to say that dynamic balancing is relevant with speed, on the last constant speed also is that balance under the free state has just been pushed down by elastic force also not carrying out, be that bead is to be stressed upon motion and definite angle in the groove of balance track of resilient clamp state at last, so balance quality is very poor.When re-using behind needs balance again, also must manually bead be taken out in the groove that stops track, and be reentered in the interior balance track of circular groove with clip.
At present, the liquid of using on high-precision grinder sprays balancing technique automatically, in several cavity volumes of the circumference equalization of using when liquid is injected balance under pressure, leave in each cavity volume do not wait than large space, at the starting operation initial stage with when stopping, be enclosed in liquid in the cavity volume because centrifugal force is little in cavity volume along circumference up and down and about flow and change, inevitably increased the vibration of this moment.Simultaneously, liquid is to have certain pressure to inject in the cavity volume, and this gunite is difficult to accurate control flow rate, and liquid solidifies when low temperature easily, and the electronic measurement and control device fabrication expense of this technology is very expensive, and application area is dwindled.
The objective of the invention is to overcome above-mentioned shortcoming, solution is in starting with when stopping and on-streamly cause uppity motion of balancing mass bead and impact, avoid the influence of the unbalanced force that after dynamic balancing, produces, reduce vibration, improve dynamic balance accuracy, a kind of both constant formula dynamic balancing simple in structure, easy to use is provided for this reason, can be again compensation automatically, the dynamic balancer of using more.
Purpose of the present invention can reach by following technical measures:
This dynamic balancer is working in coordination by balanced controls, cylinder mechanism and centrifugal mechanism, realization is controlled automatically to the overall process of the quality bead of balance, exactly in the one or more circumference guide groove that step or circular groove are formed in the annular of outer step on the circumferential outer edge of tightening cover and circumference sealing, pack into and this circumference guide groove coupling, and can free-moving two or more quality beads, Compositional balance mechanism thus.Central authorities on tightening cover have the boss cylinder to be movably arranged in cylinder one stomidium, and be connected or be linked to be integral body with upper piston in being installed in this stomidium of cylinder, pack in another stomidium of cylinder and be connected with the main piston of pull bar, this pull bar activity passes outside the through hole of upper piston and tightening cover central authorities, between upper piston and main piston, spiral compression spring is installed, is formed sealed volume at this.This cylinder is packed in the base aperture [bolt among Fig. 1 (11) is removed], then step or circular groove in the annular of circumference sealing are fixedly mounted on outside the aperture, base upper end or with the cylinder upper end and connect into integral body, step or circular groove are fixedly mounted on the outer base plate of base aperture in perhaps should annular, and respectively with the tightening cover circumferential outer edge on outer step form the circumference guide groove.Form fixed cylinder mechanism by above structure characteristic, perhaps on the basis of above structure, the central circumference of cylinder upper-end surface and tightening cover is fixedlyed connected with bolt (11), this cylinder activity is packed in the base aperture or is packed into to be fixed in the cylinder in the base aperture and is slidingly matched, and forms floating type pair of cylinder mechanism.The air of in the sealed volume of above-mentioned cylinder mechanism, packing into, and 1/5th to 2/5ths low-viscosity (mobile) liquid of this cavity volume volume of packing into, as lubricant oil, transformer wet goods, or according to dynamic balancing trace compensation size, increase and decrease within the specific limits, when liquid during less than certain ratio or no liquid, compensate inoperatively, promptly become constant formula dynamic balancing.The air valve of the intake and exhaust of at least one control cylinder pressure is installed on tightening cover, upper piston or other position of this cavity volume, end cap is installed on base or the base plate, spiral compression spring or leaf spring etc. are installed between end cap and tightening cover, spring force are acted on push down the interior quality bead of circumference guide groove on the tightening cover.On the basic equidistant bearing support of installing more than two or two of the circumference on end cap or the base, flexibly connect a lever respectively, between end of lever and end cap, spiral compression spring is installed, or on this lever, helical torsional spring is installed, under the effect of spring force, make in the stressed disk on the pull bar top of this end of lever, lever the other end installation quality flyball or fly piece, hole in the stressed place of lever bent intermediate be fixed on hole in the bearing support on end cap or the base with flexible connections such as straight pins, make the quality flyball or fly the moment that piece acts on the disk equal substantially.More than by flyball or fly the centrifugal mechanism that piece, lever and bearing support etc. are formed, also can be installed on the base plate or other position, and promptly become push rod below pull bar etc. is contained in main piston, or remove push rod etc., make main piston below axially loaded.
Purpose of the present invention can also have following measure to realize:
On end cap or base plate with the quality flyball is housed or flies this end relative position of lever of piece, the installing and locating frame, roller is installed at lever the other end end, or in the groove that disk diameter makes progress, roll, be installed on the end cap top cover or other position, on the push rod of top cover central authorities or in the tie rod hole, spiral compression spring is installed, or between main piston and base plate, coil expander is installed, perhaps on the push rod of floor below and main piston, spiral compression spring is installed, under the spring force effect, make main piston be in cylinder bottom, on end cap or other position promptly install to regulate bolt with the air valve corresponding section.Pull bar and main piston flexibly connect or are linked to be integral body.
