Rivet collector for electrical machines

The innovation relates to a rivet collector in which the Gap between which consist of a metal pipe section " the collector hub and the hub-side, dovetail-shaped The retaining lugs of the collector lamellas are filled with hardening insulating material *

It has already been proposed * but is not yet the state of the art Te.hnik., An insulating molded material for the production of collectors to use after inserting one into the hub bore matching ram under the pressure of one of the other hub face The blessing stamp introduced through a hub bore execution connecting with the space to be filled in the space between the have tube and the hub-side Lamella sets penetrates. The present innovation is based on the task of making an arrangement that allows the finished riveted collector before filling its internal cavities with insulating material on the armature shaft of an electrical machine and together with the winding of the armature with a layer of insulating material that can be poured out only then * if

the armature windings are already soldered into the collector lamellas are"

This is possible with a collector of the type described above if, according to the innovation, at least one of the two, through the collector hub against each other braced rivet rings, the behind the hub-sided tehwave-tail-shaped holding noses of the KoI-lektorlaraellen grab, has at least one channel that prevents penetration of the insulating material into the cavities the riveted collector » door from the outside allowed * For a particularly two-clawed one Arrangement be on springs never tr ing at least three over its circumference Distributed inlet ducts are provided, which differ from the circumference of the Rivet rings extend towards the axis of the bing «Such channels can easily by obliquely to the Nletringaehse Drill holes are generated «

In the drawing, three Auafifiartuagsfeeispfele of the innovation are shown ί

It shows;

Fig. 1 shows a longitudinal section through a not yet poured, but finished riveted collector,

Fig. 2 shows another collector also in longitudinal section and

3 shows a further collector, also in longitudinal section.

The collector of Fig. 1 has a number of wedge-shaped, lamellae Ii assembled next to each other to form a circular ring, which are separated from one another by interposed insulating material »foils 12 * Each of the lamellas has on the one facing the collector tube narrow long side a schwalbensahwanafSrraigen An * set 12, behind dsn two from each of the collector faces in the Grip the rivet rings 14 and 15 inserted in the circular ring bore. The rivet rings are through a meter that also serves as a collector hub

Each of the two Üietrings 14 and 13 has three over its circumference Evenly distributed, obliquely to the Hietringach.se inclined holes 20, which protrudes over the chambers 11 of the collector Begin the edge zone of the rivet rings and between the collector hub ΐβ and the dovetail-shaped approaches 13 remaining Lead cavity. The arrangement is made in such a way that during the glazing or squeezing out the space after a flowable one the introduction of hardening plastic which in dew a rivet ring existing boreholes as inflow channels for the.

In the embodiment according to FIG. 2, they are used as inlet channels for the grout serving boreholes £ 5 radially in the rental rings 26 and 27 attached *

In contrast to the previously described embodiments, the inlet channels are milled into rivet rings 89 and 30 of the otherwise similarly constructed collector according to FIG. 3 as narrow grooves from the end face of the rivet rings. In addition, narrow slots 3 $ are pierced into the collector hub 32 of the collector receiving bore 33 of the rivet rings, which the grooves 31 with; the space between the collector hub j? 2 and the dovetail-shaped projections 35 of the collector lamellas 36 in connection.
