Abstract
The invention discloses a kind of gimbal mechanism, can be used for the rotor-support-foundation systems such as washing machine.It is characterized in that gimbal chamber built with it is some can orbiting dolly, dolly two ends make mutually exclusive between two neighboring dolly equipped with magnet, and rolling bearing is provided with dolly, can make dolly orbital motion.Wherein there is a dolly that brake gear is installed, brake gear can be automatically opened up under the action of the centrifugal force.Eccentric increasing and the high vibration produced due to the self-excited vibration of gimbal mechanism near critical speed are loaded when the present invention can avoid rotor-support-foundation system from starting.
Description
Technical field：The present invention relates to a kind of gimbal mechanism, the rotor mechanisms such as washing machine are can be applied to.
Background technology：The vibration problem of rotating machinery is always the important topic of machinery industry, can using gimbal mechanism
The vibration of rotating machinery is reduced by changing rotor Mass Distribution in itself.But this kind of automatic balancing arrangement is under critical speed
The unbalance response of rotor can be increased, there is limitation in the application.
The Balance for Rotating Ball ring mechanism that such as existing some roller washing machines are used, its structure includes an annular housing,
Several steel balls are housed in cavity.When washing machine runs at high speed, roller undergarment forms eccentric load, steel ball in roller side
The side opposed with eccentric load is focused under the influence of centrifugal force, can the effectively eccentric influence of bucking-out system, reduction laundry
The vibration of machine, this is this kind of effect place of gimbal.
But there is following defect in such gimbal：Defect one, in an initial condition, due to the position of Action of Gravity Field bead
With eccentric homonymy, increase system gross decentrations.Defect two, near critical speed, the Balance for Rotating Ball ring can produce self-excited vibration,
Prevent its inner ball from synchronous with ring body holding, so as to the high vibration of rotor can be caused.
In view of this it is special to propose the present invention.
The content of the invention：The invention provides a kind of gimbal mechanism, above-mentioned the Balance for Rotating Ball ring defect can be overcome, effectively reduced
The transient oscillation of rotor.
To realize object above, the present invention provides a kind of gimbal, and its structure includes an annular solid, by outer shroud, inner ring,
Inner ring cover plate is constituted, and has a circle groove in the middle of outer shroud and inner ring as track.Annular solid built with it is some can orbital motion
Dolly, instead of the steel ball in the Balance for Rotating Ball ring.Magnetic is installed at dolly two ends, and adjacent two workshop magnet polarity is identical and mutual
Repel.Two rolling bearings are installed as wheel on dolly, can be rolled along track.One of dolly installs brake gear, small
A piece compression spring is installed between car car body and brake gear, the folding of brake gear can be controlled.
In an initial condition, for the dolly equipped with brake gear, it is interior that the elastic force that spring-compressed is produced is close to counterweight
On loop orbit, i.e., brake gear is closed, and the dolly can not be moved with respect to ring body；Simultaneously because the magnet pole between adjacent two dolly
Property it is identical, it is mutually exclusive two-by-two, dolly is scattered in ring body surrounding, it is to avoid all dollies and the phenomenon of eccentric homonymy, overcome
Defect one.
Near critical speed, due to brake gear closure, wherein a dolly is with respect to housing stationary, other dollies are in repulsion
Free movement can not be done by the dolly under effect, so as to avoid the asynchrony phenomenon that self-excited vibration causes, overcome defect
Two.
On critical speed, the centrifugal force of counterweight of braking is more than spring force, and spring contraction makes counterweight and inner ring raceway
Separate, brake gear is opened, dolly can be along balance loop orbit free-running operation；Now, dolly is relatively concentrated in eccentric load opposition
Side, the eccentric influence of bucking-out system, so as to reduce transient oscillation.
Brief description of the drawings：Fig. 1 is gimbal overall structure of the present invention；Fig. 2 is vehicle structure；Fig. 3 is with brake gear
Vehicle structure.
Specific embodiment：The present invention is further described with reference to the accompanying drawings and examples.
Gimbal internal structure of the present invention is shown in accompanying drawing 1, and (dolly number can be by experiment in gimbal for dolly 1
The optimal selection of effect, this example chooses six), wherein there is a dolly 1a with brake gear, other are common dolly 1b.Often
Individual dolly two ends are equipped with magnet, and magnet polarity is alternately distributed as schemed, because adjacent two workshop polarity is identical mutually exclusive, flat
Dolly is dispersed in around gimbal when weighing apparatus ring is static.Gimbal ring body structurc is by outer shroud 2, inner ring 3, the part group of inner ring cover plate 4 three
Into.There is a circle groove in the middle of inner ring and outer shroud as track, car wheel is clipped in the middle of track, allows dolly along rail
Move in road.Be provided with an opening in inner ring simultaneously, dolly can from this opening loading gimbal, be provided with opening cover plate by its
Seal, while the surfaces externally and internally of cover plate coincide with inner ring surfaces externally and internally, passed through when dolly is moved in gimbal.
Connected by some screws 5 between inner ring and outer shroud, inner ring and cover plate.
Gimbal vehicle structure of the present invention is shown in accompanying drawing 2, wherein 6 is car frame, dolly two ends are equipped with two axletrees 7, often
One deep groove ball bearing 8 is installed as wheel on root axle.The installation sleeve 9 at bearing inner race two ends, by bearing axially position.Axletree
There are two circle grooves at two ends, and back-up ring 10 is installed in groove by axletree axial restraint.Car body rear and front end is respectively mounted two magnets 11, uses
Screw 12 is fixed, while from Fig. 1 gimbals structures, two ends magnet should N, S polarity it is relative.
The vehicle structure with brake gear is shown in accompanying drawing 3 in gimbal of the present invention, and its structure is similar with other common dollies,
Constituted by vehicle frame 6, axletree 7, bearing 8, sleeve 9, back-up ring 10, magnet 11, screw 12, difference is have in the middle part of car body
One circular hole, wherein installing brake gear.Brake gear is made up of cylindrical shaped weight 13 and spring 14.Counterweight top and trolley
Between have a spring, when dolly is arranged in gimbal, spring is in compressive state all the time.Under critical speed, balance weight centrifugal
Power is less than spring force, and brake gear closure, dolly relative equilibrium ring is static；More than critical speed, balance weight centrifugal power is more than
Spring force, brake gear unclamps, and dolly can be relative to gimbal free movement.
Various specific embodiments described above and shown in the drawings are merely to illustrate the present invention, not of the invention
All.In the category of basic fundamental thought of the invention, every any change carried out for technical scheme
And improvement, within protection scope of the present invention.
