Abstract
The utility model provides an insulating filling ring used in a DC (direct-current) motor armature. The insulating filling ring is characterized by comprising a ring body; tooth-shaped protrusions are disposed on a side edge of the ring body; and the tooth-shaped protrusions and the ring body are formed into a whole. The insulating filling ring is utilized to fill a cavity in a DC armature end portion and can prevent imbalance caused by the cavity; and since substances which obstruct the motor performance, like carbon power and copper powder, are not gathered in the cavity any longer, noise caused by the cavity is prevented.
Description
Technical field
The utility model belongs to motor technology field, relates in particular to a kind of insulation filling ring for DC motor armature.
Background technology
The armature of DC motor or the phase-wound rotor of alternating current machine are in service in High Rotation Speed state motor, the armature enamelled wire of winding-type can form a local cavity therein after the Shape correction of end, cavity inside is easily assembled carbon dust and the copper powder that brush friction is left over, may damage insulation system, or cause the noise of running.Generally to carry out Coating glue protect with epoxy resin again after insulation dipping lacquer now; and insulating varnish and epoxy resin are all mobility liquid; can fill smaller gap; the for example gap between enamelled wire, but do not possess for the larger cavity forming in end the condition being full of.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provides a kind of insulation filling ring for DC motor armature, it is characterized in that comprising ring body, and described ring body side is provided with dentation, and described dentation and described ring body are integrated.
The material of described ring body and dentation is bakelite.
The beneficial effects of the utility model are: use the utility model to fill up the cavity of DC armature end, avoid the imbalance that caused by cavity, in cavity, not assembling carbon dust, copper powder etc. and hinder the material of motor performance, avoided the noise being produced by cavity.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of DC motor;
Fig. 2 is the A-A profile of Fig. 1;
Fig. 3 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further:
In figure, 1, DC motor; 2, armature; 3, ring body; 4, dentation.
As shown in Figures 1 to 3, ring body 3 sides are provided with dentation 4, and dentation 4 is integrated with ring body 3, and the material of ring body 3 and dentation 4 is bakelite.Start before rule at DC motor armature 2, the utility model is bonded in to the end of DC motor 1 with the glue of a little, then carry out rule operation and carry out follow-up armature 2 processing and fabricatings.
Have been described in detail of the present utility model by embodiment above, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variation and improvement etc. of doing according to the utility model application range, within all should still belonging to patent covering scope of the present utility model.
