Abstract

The utility model discloses a laid band integrated collector ring for an electric machine, belonging to the main component of the electrical motor, in particular to the wound rotor electrical motor. The purpose is to provide the laid band integrated collector ring for the electric machine. The utility model is characterized in that: the laid band integrated collector ring for an electric machine is improved on the basis of the general collector ring, and the external surface layer of a pipe sleeve is improved into a laid band. The utility model has the advantages that the surface of the laid band is smooth; the external appearance of the banding surface is smooth and bright; the adsorbability of the carbon dust prevention is great; the insulation resistance and the reliability are high; the integrity of the structure is great; the gum is solidified to form an integral in using; the service life is long; the economical efficiency is great; the difficulty of the technological operation is increased, and the cost price is increase, but the overall evaluation is high.

Description

Motor does not have latitude band integral type collector ring

Technical field

The utility model belongs to motor, the particularly critical piece of phase-wound rotor motor.

Background technology

With reference to Fig. 2, manufacture motor general expression collector ring for many years, be after the part assembling is pressed into pipe box, adopt the glass fiber rope that insulating material is carried out colligation, paint-dipping drying then.This general expression collector ring exposes problems in the motor long-time running is used:

(1) shape is rough in the shape of a spiral for glass fiber rope itself, the glass fiber rope row around the time have a concavo-convex slit of nature, the collector ring that winds up is in long-time running, the carbon ash that carbon brush and slip ring friction produce easily is adsorbed on the more coarse glass fiber rope colligation face of collector ring, cause the rotor insulation resistance to decline to a great extent because of the conductivity of carbon ash, and winding motor is when starting, the interannular voltage of collector ring does not wait up to hundreds of to thousands of volts, in using, the user often occurs that motor collecting ring is creepage to cause short circuit to puncture, when serious even the related rotor coil that burns out, cause the substantial equipment interruption of service.(2) motor collecting ring is subjected to action of centrifugal force glass fiber rope easily to get rid of diffusing getting loose in operation process, causes motor to shut down repairing.So general expression collector ring shortcoming is the colligation material with glass fiber rope shape in the shape of a spiral; Outward appearance colligation face is coarse; The carbon dust resisting adsorptivity is poor; Insulation resistance and reliability are low, and structural integrity is poor, and in use jag is easily loose; Useful life is general, easy creepage generation short circuit; Less economical; Though technological operation is simple, cost is lower, overall merit is general.When above-mentioned motor collecting ring is analyzed and researched with the problem of glass fiber rope colligation existence, select for use multiple scheme to compare, as integral die formula, insulation watt formula, no latitude band turning mode, all because of complex process, manufacturing expense is too high, and environmental pollution is difficult to carry out greatly.

Summary of the invention

The purpose of this utility model is to provide a kind of motor not have latitude band integral type collector ring.The utility model is realized with following mode: a kind of motor does not have latitude band integral type collector ring, and it has pipe box 1 in motor one end and its formation one, and there is slip ring 4 its outside; Outer surface at pipe box 1 is surrounded by lining 2, mica 3 successively from level to level, it is characterized in that having or not latitude band 5 and being solidified into integral body at the outer surface of 3 layers on mica.No latitude band (glass fiber resin 2841-W) is a kind of insulating material in field of motor manufacturing, and prolonged application is in the cylindrical colligation of motor line winding rotor.Motor does not have the whole collector ring of latitude band with the outermost aspect of this no latitude band (glass fiber resin 2841-W) as pipe box 1, and substantial characteristics and progress are arranged.The utility model has the advantages that: the colligation material is smooth with no latitude belt surface; Outward appearance colligation face smooth; The carbon dust resisting excellent adsorption; Insulation resistance and reliability height; Structural integrity is good, and gelling in use is solidified into integral body; Long service life; Good economy performance; Though the technological operation difficulty slightly increases, cost slightly increases, the overall merit height.

Fig. 2 is a general expression collector ring structural representation.

Fig. 3 is a structural representation of the present utility model.

Fig. 4 is the utility model structural representation in process of production, is the A-A section of Fig. 3.

Embodiment

Now in conjunction with the accompanying drawings the utility model is described in further detail.With reference to Fig. 3-Fig. 4, when the utility model is made, must guarantee that no latitude band integral type collector ring is level and smooth in the technology winding process.For reaching no latitude belt surface brightness effect, test with multiple auxiliary material, when mode selected is no latitude band 5 colligations to certain thickness, not having latitude band 5 during colligation can not jag and crimping, prevent the film 6 of adhesion around one deck on its surface, on film 6, add one deck certain thickness and harder material cardboard 7, reach the purpose of compacting again with the harder material cardboard 7 of jag band 8 tightens.Behind paint-dipping drying, remove jag band 8, harder material cardboard 7, anti-adhesion film 6 respectively then.This moment collector ring no latitude belt surface light and be solidified into integral body.

Claims

1, a kind of motor does not have latitude band integral type collector ring, and it has pipe box [1] in motor one end and its formation one, and there is slip ring [4] its outside; Outer surface at pipe box [1] is surrounded by lining [2], mica [3] successively from level to level, it is characterized in that having or not latitude band [5] and being solidified into integral body at the outer surface of mica [3] layer.
