Abstract
Electromagnetic self-balancing head is made up of stator, rotor and steady arm.Adopt the stator and the rotor of common asynchronous moter or stepper motor, add the balance mass piece on the rotor, rotor and rotating disk are affixed.Steady arm is fixedlyed connected with the rotating shaft that is balanced part with axle sleeve.The steel ball location is arranged between rotating disk and the steady arm; rotate at stator effect lower rotor part; rotating disk pushes away out pilot hole with steel ball; rotor is rotated relative to axle sleeve; counterbalance weight just moves relative to being balanced part on the rotor, and until balance, stator no longer acts on; rotor is promptly rotated with being balanced part the promotion of rotating disk by steel ball in the steady arm synchronously by rotating shaft, realizes not shutting down self-poise.
Description
The invention belongs to the balance component of rotating machinery.
Many rotating machineries are used to handle abrasive materials, Corrosive Materia or adhesion material.Thereby the working rotor of many rotating machineries is in other asymmetric working environments such as asymmetric hot pressing, air pressure, and the material in the rotor distributes and quality usually changes, and needs often carry out transient equilibrium again to rotor-support-foundation system.Usually transient equilibrium need be shut down and be carried out, and causes bigger economic loss, so people are seeking not carry out transient equilibrium under the halt condition for a long time, and the best way adopts automatic-balancing system exactly.
Automatic-balancing system comprises two parts: a part is a self-balancing head, and another part is a controller.The self-balancing head kind is existing multiple at present.First-class as jetting liquid formula self-balancing head, mechanical type self-balancing head, pneumatic type self-balancing head, flow water self-balancing head and electrodynamic type self-equilibrating.But liquid is volatile, and emitted dose is difficult to reasons such as accurately control, and the injecting type self-balancing head only is applied on the less demanding device of emery wheel isoequilibrium; And the self-balancing head of other pattern makes to be difficult to guarantee balance quality in the high speed centrifugation field, so all do not enter practical stage owing to complex structure.
The purpose of the invention is a kind of simple in structure, self-balancing head with practical value of design, can under the halt condition rotating machinery not carried out self-poise.
The organization plan of this self-balancing head is to be made of stator 4, rotor 3 and steady arm.Rotor and stator can be selected the rotor and the stator of common asynchronous moter or stepper motor for use, have the balance mass piece on the rotor, and rotor is fixedlyed connected with rotating disk 2.Steady arm is fixedlyed connected with the rotating shaft 12 that is balanced part by axle sleeve 1.Rotating disk 2 endoporus and sleeve outer circle cunning are joined, and there is pilot hole rotating disk and steady arm corresponding section, and steel ball 9 usefulness springs are pressed into pilot hole, and spring pressure is regulated by set screw, make the rotation that is balanced part can't make the steel ball dislocation; But under a certain size moment loading of stator; rotating disk can push away out pilot hole with steel ball; the rotor rotating disk is to rotate relative to axle sleeve; the balance mass piece just moves relative to being balanced part on the rotor; until reaching balance; stator no longer acts on after the balance, and the rotating disk rotor promptly rotates it by the effect of rotating shaft by steady arm and steel ball automatically synchronously with being balanced part, realizes not self balancing purpose under the halt condition.
Description of drawings:
Fig. 1 is the synoptic diagram of a kind of embodiment of this programme;
Fig. 2 is the synoptic diagram of another kind of embodiment.
Embodiment with reference to the description of drawings scheme:
As shown in Figure 1, steady arm comprises axle sleeve 1, positioning disk 7 and the binding dish 5 that is fixed in the rotating shaft 12 that is balanced part.Be connected by screw 6 respectively between positioning disk and binding dish and the axle sleeve, because rotating disk 2 joins with the axle sleeve cunning, so rotor and be balanced the part rotating shaft and can relatively rotate.Porose 10 in order to locking ball on the binding dish, and pilot hole 11 is arranged on the rotating disk corresponding with it, and steel ball 9 is pressed into pilot hole by spring leaf 8, and spring leaf is regulated preload pressure by set screw 13 and is pressed between binding dish and the positioning disk.
As shown in Figure 2, steady arm has only the axle sleeve 1 of fixedlying connected with the rotating shaft 12 that is balanced part, and the rotating disk 2 and the axle sleeve cunning of fixedlying connected with rotor 3 are joined.Pilot hole 16 and little arc groove are arranged on the axle sleeve, in groove, slide after steel ball 9 breaks away from pilot hole, axially dislocate with the relative axle sleeve of preventing rotor.With porose 14 on the 16 corresponding rotating disks 2 of hole, steel ball 9 and compression spring 15 are arranged in it, steel ball can be pressed into pilot hole 16 by the spring preload pressure.By set screw 17 adjustable springs preload pressures.
This electromagnetic self-balancing head and its remarkable result of background technology comparison are: being balanced in the part course of work can autobalance, needn't shut down and simple in structure, easy to use, economic effect is considerable.
