Description

The field coil in tool air channel

Technical field

The utility model relates to the environmental mechanics test and uses electric vibration table, is specifically related to the field coil in air-cooled electric vibration table tool air channel.

Background technology

Electric vibration table is as main vibration test and dynamic characteristic test instrument, but the actual condition of simulation test sample, the structural strength of examination product, find the initial failure of product, therefore be widely used in industries such as national defence, space flight, aviation, communication, electronics, automobile, motorcycle, household electrical appliances.

Electric vibration table utilizes the electric and magnetic oscillation principle design, and its structure mainly is made up of several parts such as stage body, magnetic cylinder, field coil, moving-coil, bearing guiding device and cooling devices.Basic functional principle is: the field coil that is wound on the magnetic cylinder feeds direct current generation stationary magnetic field, the moving-coil that has work top and drive coil is connected with exchange current and produces alternating magnetic field, the moving-coil that produces alternating magnetic field is arranged in the stationary magnetic field, owing to interact between alternating magnetic field and the stationary magnetic field, producing---exciting force, the table top that pushes the work forward vibrates back and forth around the centre of oscillation.Electric vibration table is when work, and field coil and drive coil just will discharge a large amount of heats after feeding electric current, and heat can't shed in stage body, when heat acquires a certain degree, will damage assemblies such as field coil, drive coil, short-circuited conducting sleeve.How cooling off stage body is the problem that electric vibration table must solve, and therefore existing electric vibration table all is furnished with cooling system, and cooling system has air-cooled and the water-cooled dual mode.Water-cooling pattern good cooling results, but complex structure, the trouble spot is many, and needs devices such as configuration water cooling tower, heat exchanger, and therefore the cost height, generally just adopts water-cooled to large-scale stage body.And air cooling way is realized conveniently, cost is low, and is existing for more small-sized stage body employing air cooling way.

Establish one group of cooling air channel in the existing air-cooled electric vibration table stage body simultaneously to field coil and drive coil cooling, air outlet is located at the stage body bottom and adopts blower fan to aspirate in the air outlet negative pressure, make and distinguished and admirablely take away heat through the field coil outer surface, but field coil is the annular entity that is gone out by the lead coiling, lead forms a plurality of winding circles diametrically in this annular entity, on annular solid is axial, form a plurality of winding layers, reach winding layers and interlayer between winding circle and circle closely against no gap, inside does not form the ventilation air channel, wind can't enter field coil inside, the field coil internal heat can't shed, and cools off insufficiently, causes air-cooled cooling effect poor.

Summary of the invention

The utility model purpose provides the field coil in a kind of tool air channel, to solve field coil internal heat dissipating difficulty in the prior art, to cool off inadequate technical matters.

For achieving the above object, first kind of technical scheme that the utility model adopts is: the field coil in a kind of tool air channel, be the annular solid that is turned to by lead, lead directly upwards forms a plurality of winding circles at annular solid in this annular solid, forms a plurality of winding layers on annular solid is axial; Directly make progress at annular solid, described winding circle is divided into several circle groups, and each circle group all is made of a plurality of winding circles that interior foreign minister leans on, and between each adjacent circle group around the circumferential uniform insulation filler rod that is embedded of annular solid, support out axial ducts with this.

For achieving the above object, second kind of technical scheme that the utility model adopts is: the field coil in a kind of tool air channel, be the annular solid that is turned to by lead, lead directly upwards forms a plurality of winding circles at annular solid in this annular solid, forms a plurality of winding layers on annular solid is axial; It is characterized in that: annular solid axially on, described winding layers is divided into several layers group, each layer group is made of a plurality of winding layers that lean on mutually up and down, and between each adjacent layer group around the circumferential uniform insulation filler rod that is embedded of annular solid, overhang the radial passage with this.

The variation of the related content in the technique scheme and being explained as follows:

1, in the such scheme, " being the annular solid that turns to by lead; lead directly upwards forms a plurality of winding circles at annular solid in this annular solid; on annular solid is axial, form a plurality of winding layers ", each winding circle described in the words is meant that in the existing field coil coiling, lead is the individual pen of stacked on top formation in the axial direction; Described each winding layers is meant in the existing field coil coiling, and lead piles up the individual layer of formation inside and outside diametrically in the plane.

2, in the such scheme, the direction of described " up and down " " inside and outside " is by the laying state definition of as shown in Figure 1 field coil, the field coil shown in the accompanying drawing 1 axially promptly be above-below direction, in the place, axle center that the footpath makes progress is, outside the periphery is.

3, in the such scheme, cooperate for offseting between the opposite face of described insulation filler rod and adjacent turn group or layer group, when field coil is installed in when using in the stage body, field coil integral body is fixed by magnetic cylinder body integral body, for field coil convenient transportation before the stage body of packing into, can adopt bonding agent will insulate filler rod and adjacent turn group or the preliminary cemented in place of layer group.

4, in the such scheme, described " insulation filler rod " should adopt the material of hardness, high temperature resistant, insulation, the best bakelite bar that adopts.

The utility model design concept is: the utility model support between the circle group of field coil or layer group to make progress the insulation filler rod week uniform shaft to or radially air channel, field coil winding layers and layer have in the past been broken through, circle with enclose between closely against gapless traditional structure, make that wind can enter the heat that field coil inside is taken away in field coil inside through the air channel when air-cooled, solved the inadequate difficult problem of the internally air-cooled cooling of field coil.

When the utility model uses, on the stage body the logical air inlet of cooling air should with field coil in specifically be the design that matches of axial ducts or radial passage, when use be tape spool to the field coil in air channel the time, should on the magnetic cylinder cap, offer air inlet longitudinally, when what use is when being with the field coil of radial passage, should offer the air inlet of side direction on magnetic cylinder ring.

When the utility model is made, for the field coil of tape spool to the air channel, can first coiling inner turns group, place insulation filler rod, the circle group of coiling outside more then; Certainly, also can be earlier after coiling goes out inside and outside each circle group respectively, will be nested inside and outside each circle group again, embed the insulation filler rod betwixt.For the field coil of band radial passage, can first coiling go out the layer group of lower floor, place the layer group that goes up insulation filler rod and then coiling upper strata then; Certainly, after also coiling goes out each layer group respectively, put the insulation filler rod down organizing the upper edge layer by layer, and then pile up the layer group on upper strata.

The utility model compared with prior art has the following advantages:

Since the utility model in the field coil indoor design air channel, can be internally air-cooled through the air channel to field coil, take away inner heat, solved air-cooled all the time electric vibration table inadequate problem cooled off in field coil inside, improved air cooling effect.
