Abstract

The utility model relates to an electromagnetic self-balance head, comprising a stator, a rotor and a locator. The utility model adopts the stator and the rotor of common asynchronous motors or stepping motors, the rotor is added with a quality balance block, the rotor is fixed with a rotary disc, and a locator is fixedly connected with the rotating shaft via a shaft sleeve, and the rotating shaft is connected with the balance component. A steel ball is arranged between the rotary disc and the locator for positioning, the rotor can turn under the action of the stator, so the rotary table can push the steel ball away from a position hole, and the rotor can relatively turn to the shaft sleeve. The balance block on the rotor can be relatively moved by the balance component until balance, and the stator does not act any longer. So the rotor can synchronously turn with the balanced component by the pushing of the rotary disc from the steel ball in the locator, and therefore, the utility model can accomplish automatic balance without stopping machines.

Description

Electromagnetic self-balance head

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 dynamic balancing again to rotor-support-foundation system.Usually dynamic balancing need be shut down and be carried out, and causes bigger economic loss, so people are seeking not carry out dynamic balancing under the halt condition for a long time, and the best way adopts automatic-balancing system exactly.

Automatic-balancing system comprises two-part: 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 balancing.But liquid is volatile, and emitted dose is difficult to reasons such as accurately control, and the jet-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 use value of design, can under the halt condition rotating machinery not carried out autobalance.

The organization plan of this self-balancing head is to be made of stator 4, rotor 3 and positioning work piece.Rotor and stator can be selected the rotor and the stator of common asynchronous moter or stepper motor for use, have the balancing mass piece on the rotor, and rotor is fixedlyed connected with rotating disk 2.Positioning work piece 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 positioning hole rotating disk and positioning work piece corresponding section, and steel ball 9 usefulness springs are pressed into positioning hole, and spring pressure is regulated by adjusting 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 positioning hole with steel ball; the rotor rotating disk is to rotate relative to axle sleeve; the balancing 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 positioning work piece and steel ball automatically synchronously with being balanced part, realizes not self balancing purpose under the halt condition.

Description of drawings:

Fig. 1 is a kind of embodiment's of this programme a schematic representation;

Fig. 2 is another kind of embodiment's a schematic representation.

Embodiment with reference to the description of drawings scheme:

As shown in Figure 1, positioning work piece 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 positioning disk, and positioning hole 11 is arranged on the rotating disk corresponding with it, and steel ball 9 is pressed into positioning hole by spring sheet 8, and spring sheet is regulated preload pressure by adjusting screw 13 and is pressed between binding dish and the positioning disk.

As shown in Figure 2, positioning work piece 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.Positioning hole 16 and little arc groove are arranged on the axle sleeve, in groove, slide after steel ball 9 breaks away from positioning 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 pressure spring 15 are arranged in it, steel ball can be pressed into positioning hole 16 by the spring preload pressure.By adjusting 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.
