Description
Technical field
The utility model relates to a kind of collector ring, particularly relates to a kind of wire wound asynchronous motor collector ring.
Background technology
Collector ring is the vital parts of wire wound asynchronous motor, wire wound asynchronous motor reduces starting current by collector ring in rotor loop series resistance, improve starting torque, shorten the starting time, carry out step speed regulation, be widely used in as driven equipments such as ball mill, grog cellar for storing things, air blasts.
When wire wound asynchronous motor uses for a long time, brush ash can be gathered between slip ring and brush, is bonded in slip ring and surface of the electric brush, and cause slip ring and brush to run bad, mechanical consumption rises fast with electric consumption, so that produces spark, wear of brush quickening.Slip ring wearing and tearing aggravation.In addition because practical service environment is very complicated, ventilate unfavorable, dust fills the air, humidity over limit, height above sea level are higher, maintain the factors such as inconsiderate, also can aggravate the situation generation that collector ring frequently breaks down.
Existing collector ring in actual use, easily there is arcing, short circuit, over the ground, even the fault such as to burn, produce these faults main because creepage distance, dielectric strength nargin not, fouling resistance ability and adaptation to high altitude ability low, namely reliability is not enough, cannot meet the demand of client.
Utility model content
The purpose of this utility model is to overcome the above problem that prior art exists, and provides that a kind of margin of safety is higher, adaptive capacity is stronger, and the wire wound asynchronous motor collector ring of longer service life, meets customer need to greatest extent.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the utility model is achieved through the following technical solutions:
A kind of wire wound asynchronous motor collector ring, comprise slip ring spider and installing at least one slip ring thereon, the upper surface of slip ring spider is coated with support insulating cement, run through between slip ring and be connected with conducting rod, conducting rod end is connected with rotor leading-out wire, the upper end of slip ring is connected with brush, is connected between brush by conducting ring, and described brush and adjacent conductive interannular are also provided with sallop screen; The surface of described support insulating cement is surrounded with netted without latitude band, the two ends polyester fiberglass marginal belt rib prevented without the landing of latitude band; Described slip ring is positioned at it and offers spiral wind ditch with the connecting portion of brush.
Further, the connecting portion silver-bearing copper of described conducting rod and slip ring welds, and is arranged with locking jam nut with the connecting portion of rotor leading-out wire;
Further, described sallop screen is preferably the epoxy laminated board of 2 ~ 5mm.
It is further, described that netted to be preferably 3mmF level without latitude band netted without latitude band.
The beneficial effects of the utility model are:
1, between adjacent brush and conducting ring, set up sallop screen, can increase electrical separation between conductor at double, the conductivity dust such as effective obstruct brush ash or foreign material fill the air alternate, thus effectively prevent arcing or short circuit.
2, the rack surface of slip ring attachment is after Conventional insulation, more wrapped netted without latitude band in its surface, can axially fasten on the one hand, improve again the insulation margin of holder part to slip ring; Improve slip ring fouling resistance ability on the other hand, and the adaptive capacity to High aititude environment for use.
3, be opened in the spiral wind ditch of slip ring surface, slip ring surface, surface of the electric brush ventilation and heat can be strengthened on the one hand, reduce surface of the electric brush temperature; Can effectively brush ash be got rid of clean on the other hand.
