Toroidal core

During the transport »handling, wrapping and installation of It is objects made of high-quality magnetizable materials Do not avoid these items being certain mechanical * It is well known that high-quality magnetizable © materials are already suffering through Relatively small external mechanical influences are therefore already a considerable loss of their magnetic values Facilities have been proposed? which the objects made of high-quality magnetizable materials against to protect mechanical stresses »Specially manufactured protective troughs are used * in the band ring cores, for example made of high-quality magnetizable materials are embedded »so that they are not exposed to external stresses Deterioration of their magnetic properties · This solution has been found, however, not in all cases to be satisfactory the nuclei within the iröge proved to have a certain amount Have leeway and for certain purposes this results in a certain "[instability of the magnetic conditions * But even with a determination of the core in the srog through Adhesion at individual points cannot be avoided when the individual layers of the core are against each other in the event of vibrations be able to shift something, which also results in an uncertainty in the magnetic relationships »

It has also become known to provide the sand ring core © with a mechanically rigid cover so that the later applied winding cannot exert any pressure on the core Single disks or half-ring shells, which lie axially or radially against the core from the outside, are formed. In these embodiments, there is also the risk that due to

of the necessary play in the construction of the cores in these silences or Shells the core is not firmly embedded and in particular its individual positions can shift against each other »

Since in the case of highly sensitive, magnetizable materials, as already mentioned, even slight mechanical deformations are disadvantageous affect their magnetic values, durea the present Invention a slot device for hingband cores are specified, which the disadvantages of the previously known protection arrangements avoids »

The invention relates to a toroidal tape core made of high-quality magnetizable materials and protected against mechanical deformation Inside of the Bingfcan.dkerjj.es. well-fitting cylinder is surrounded, and that a layer of elastic, heat-resistant plastic is applied to the end faces of the core and an insulating area * that slits the core from mechanical loads and at the same time connects the edge parts of the cylinder with one another »

As a material for the cut, resilient. Cylinder can metallic materials are used or impregnated with synthetic resin non-metallic materials such as # B * - © liiamerfolien (manufactured for example from GrlimraerpiiTver and Eunsthara powder), glass fiber fabric or asbestos fabric »on the end faces of the band ring cores applied elastic isiteefeestSnclige layer consists z, B # Silicone rubber, while ein.Gremisoii from plastics and for the insulating compound applied to this elastic layer we use inorganic hill substances &

The ratio of the mixture of plastics and inorganic Fillers is chosen so that, based on weight related, the filler makes up more than half of the mixture used * 33er inorganic filler consists for example made from grimmer powder, quartz, slate or (3-stone flour, the synthetic resin, for example, made of ethoxylin resin or silicone resin *

The elastic, hit-resistant one applied to the band ring core Plastic layer has multiple meanings On the one hand, it prevents the ropes »from being damaged during the hardening process on aie applied insulating compound between the individual layers penetrate the core and there inadmissible tension cause"

On the other hand, the elastic layer ©, tar also creates some small Eestspannussgenj- the fe @ i the hardening of the synthetic mass or in the case of thermal stresses of the embedded Kernes can still occur, absorbed and thereby by the core held back »Furthermore, this leaves the © layer lose its elasticity The properties of the core suffice scope for oils with the Magnetization connected bimensismantiing {magnetostriction) *

The resilient ones surrounding the band ring core inside and outside Cylinders are appropriately a little higher than the Bandringkerii »- The Igolierstoff applied to the elastic layer can thereby the one between the protruding bands of the cylinder fill in the resulting space

For some purposes it is advantageous to apply the elastic layer to the end faces of the band ring core with synthetic resin at points! zn glue * This ensures * that the core is already solidified to the extent that before the elastic »heat-resistant layer is applied,» that no mechanical pretension can arise from the applied elastic layer «

So that the core is fixed on the one hand * but on the other hand a low mobility of the material due to operational © Thermal expansion or magnetostriction is possible, between the outer and inner cylinder and the hinge core, one elastic »heat-resistant plastic layer can be arranged« The cylinder can be wiped with the elastic layer & vein be glued directly to the core *

Cores A particular advantage in the construction of the invention / is in the use of the cut open resilient cylinders "

This makes it possible to always have an and. The same cylinder size can be used for band ring kerxia of different diameters within a certain range «! This simplifies storage · The costs for the production of the cylinders are also lower, because only a few types need to be produced in larger quantities *

In addition, there is a favorable waste factor for the finished ring core because the resilient, cut open cylinder means that these fit tightly to the pins and the clearance otherwise required with rigid protective troughs or rigid visor shells is reduced. For insulation against the ring cores ■■ on windings made of metallic materials, cylinders made of metallic materials can be fitted with an insulating wire? for example made of hardenable 'plastics' *

The accompanying drawing shows an example of the invention. Fig. 1 shows a cross-section through the lingual tape core shown in a top view in Fig. 2. Fig. 3 shows a cross-section through a single-tape core in which on the end faces of the elastic * hit & ebeatä & ended layer and inner cylinder is directly schenschiciit applied to the Bingbandkern without an elastic Zw ^ "She Fig x 4" shares a cross section of a Hing tape core is ^ directly applied and exit this' a further © layer bus insulating is upset *
