Abstract
The utility model relates to an armature with an insulation fixing ring, which solves the problems that the existing installed ferromagnetic material fixing ring generates technological complexity to cause insulating paint to easily chip and formed vortex effect influences the performance of the armature. The insulation fixing ring is installed at a weld part of an armature winding and a ring collector. Consequently, the production and assembly technology of the armature is simplified; high magnetic wave and electromagnetic noise are decreased; the performance of the armature is enhanced.
Description
Technical field
The utility model is a kind of armature that has the insulating properties retainer ring.
Background technology
The retainer ring of armature is the excessive weld strength that surpasses armature winding and commutator of centrifugal force that prevents that the armature high speed rotating from producing, and winding is thrown away parts of the armature that plays the role of fastening from commutator slot.The present retainer ring that armature adopted is the ferrimagnet retainer ring.Owing to when the ferrimagnet retainer ring uses, have following problem:
1) the ferromagnetism retainer ring is a conductor, in use, being mated between the part (commutator, winding) at ring to increase an insulating barrier (this film mostly is glass fiber), when this just makes production and assembly, the complexity that has increased technology promptly goes up insulating barrier earlier and is pressed into retainer ring again, divides two ones and finishes the work of press fit ring;
2) degree of adhesion of ferrimagnet and insulating varnish is very low, and especially the variations in temperature along with environment is big;
3) difference of the thermal coefficient of expansion of ferrimagnet and insulating varnish is big, causes insulating varnish easily cracked;
When 4) armature is worked, can produce induced current on the ferromagnetism retainer ring, form the performance that eddy current effect influences armature.
Summary of the invention
The purpose of this utility model provides a kind of armature that makes the insulating properties material retainer ring of assembly process process simplification, to solve above-mentioned existing problem.
Implementation procedure of the present utility model is: earlier armature shaft, the little assembly of armature core, insulation dististyle, armature winding, commutator by axial compression go into, after flower is inserted, turns round in insulating paper insertions, winding moulding, winding, commutator is pressed into, copper cash is gone into groove, the several operations of welding assemble, at armature winding and commutator weld installation insulating properties retainer ring; Said insulating properties retainer ring mostly is the material that glass fiber and epoxy resin etc. have insulating properties.
Advantage of the present utility model is:
1, simplifies the structure, adopt the retainer ring of insulating properties material to replace ferromagnetism retainer ring and dielectric film; Thereby simplified the production assembly technology of armature.The ferromagnetism retainer ring, owing to itself can conduct electricity, so when using the ferromagnetism retainer ring, must increase the material of an insulating properties between ring and armature, this just makes when producing, and go up earlier insulating material press fit ring again, divides two ones and finishes the retainer ring work that is pressed into; And the insulation retainer ring, this just can be finished by a pressure ring technology as insulating material.
2, the intensity height of material.The intensity of the retainer ring of ferrimagnet generally is about about 400kg power, and the retainer ring intensity of insulation material can reach more than the 1600kg power.
3, can reduce the eddy current effect of armature.During armature work, have the armature of ferromagnetism retainer ring, on the ferromagnetism retainer ring, can produce induced current, form eddy current effect, thereby influence the performance of armature; And just can avoid producing induced current with the non-magnetic fixed ring, thereby the heat of armature reduces, has reduced high magnetic wave, has reduced electromagnetic noise, the performance of armature also increases.
4, better with the adhesiveness of commutator, armature winding insulating varnish.The degree of adhesion of ferrimagnet and insulating varnish is low, and two kinds of material coefficient of thermal expansion difference of coefficients are big, and the range of temperature of armature work is big, thus the lacquer easily crack, long insulating varnish of time is cracked easily, also can cause retainer ring to come off, lost efficacy; And insulating properties material armature retainer ring is originally as insulator (mostly being resin material), and can become one well with the insulating varnish adhesiveness, and the retainer ring of insulating material and the thermal coefficient of expansion of insulating varnish are very nearly the same, therefore, when armature was worked, even range of temperature is very big, the adhesiveness of two kinds of materials was also highly stable, avoided the difference owing to the too high two material coefficient of thermal expansion coefficients of temperature, insulating varnish produces the possibility cracked, that retainer ring comes off.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of retainer ring;
Embodiment
Describe in detail below in conjunction with accompanying drawing: as shown in the figure, insulation dististyle 2, the little assembly 3 of armature core, commutator 6 are installed on armature shaft 1, insulating properties retainer ring 5 are installed at armature winding 4 and commutator 6 welds; Said insulation retainer ring more than 5 adopts glass fiber and epoxy resin to make, and also can be other insulating material.
In addition, the armature that has also has retainer ring at afterbody, also can adopt this insulating properties material retainer ring.At armature winding and commutator weld the insulating properties retainer ring is installed.
