Description

W znanych komutatorach. wycinki ax (fig. 1) sa wraz ze skrzydelkarfii bt wyko¬ nane calkowicie z miedzi, wieksze zas wy¬ cinki sa wyrabiane przez skladanie wyci¬ nanych lub ciagnionych czesci z miedzi.W skrzydelka miedziane bx tych wycin¬ ków Oi wlutowane sa wedlug znanych spo¬ sobów konce ct uzwojen twornika.Przy wyrobie wycinków z wegla sztu¬ cznego nie mozna jednak postepowac w ten sposób, poniewaz wlasnosci wegla róznia sie zasadniczo i istotnie od wlas¬ nosci miedzi i skrzydelka z wegla nie mo¬ ga byc lutowane. Wynalazek niniejszy umozliwia przy wykonaniu wycinków z wegla, najlepiej wegla siztucznego, pola¬ czenie konców uzwojenia twornika w spo¬ sób dotychczas w praktyce stosowany, najlepiej przez lutowanie. Do osiagniecia tego celu zaopatruje sie wedlug wynalaz¬ ku szlifowane lub wytlaczane wycinki we¬ glowe a2 (fig. 2) w skrzydelka metalowe 62. Z tyjni skrzydelkami laczy sie uzwo¬ jenie c2 twornika wedlug dotychczas zna¬ nego sposobu. Skrzydelka metalowe mo¬ ga byc przymocowane np. za pomoca srub, zacisniecia lub przez odlanie. Przy odle¬ waniu wskutek cisnienia spowodowanego skurczem osiaga sie mocne mechaniczne i dobre elektryczne polaczenie miedzy *) Wlascicielka patentu oswiadczyla, ze wynalazcami sa Hans Zóllner w Lauf n, Pegnitz i Philipp Yoegler w Rolhenbach n, Pegnitz.di Do opisu patentowego Nr 31933 F/a. 4 Ti fwycinkiem i skrzydelkiem. Polepszenie wlasnosci pnzeplywu pradu ze skrzydelka metalowego do wycinka weglowego osia¬ ga sie przez powlekamie konca wycinka metalem, nip. przez miedziowanie, po czym skrzydelko przymocowuje sie. Gdy skrzy¬ delko jest wykonane np. z trudno lutuja¬ cego sie metalu, mozna je dodatkowo po¬ kryc miedzia w celu ulatwienia polacze¬ nia z nia konców uzwojenia przez lutowa¬ nie. Wreszcie koniec wycinka sam moze byc uksztaltowany na skrzydelko meta¬ lowe przez powleczecie miedzia sposobem galwanicznym lub przez natrysk, a wów¬ czas skrzydelka wycinków nie musza byc odlewane z innego metalu. PLIn well-known commutators. the slices ax (fig. 1) are made entirely of copper together with the flaps, and the larger cuttings are made by assembling cut or drawn parts of copper. The copper flaps bx of these cuttings Oi are soldered according to known the end of the armature windings. However, this cannot be done in the production of the cut carbon, since the properties of the carbon differ substantially and significantly from those of copper and the carbon wing cannot be soldered. The present invention makes it possible to join the ends of the armature winding in the hitherto practicable manner, preferably by soldering, in the production of carbon slices, preferably plastic carbon. In order to achieve this goal, the ground or embossed carbon sections a2 (FIG. 2) are provided with metal wings 62 according to the invention. The armature winding c2 is connected to the rear wings according to a previously known method. The metal wings can be attached, for example, by means of screws, clamps or by casting. When casting through pressure caused by contraction, a strong mechanical and good electrical connection is achieved *) The patent owner stated that the inventors are Hans Zóllner in Lauf n, Pegnitz and Philipp Yoegler in Rolhenbach n, Pegnitz.di To patent description No. 31933 F / and. 4 Ti with clipping and flap. The improvement of the properties of the current flow from the metal wing to the coal sector is achieved by coating the end of the section with metal, nip. by copper plating, then the wing is attached. When the box is made of, for example, hard-to-solder metal, it may additionally be covered with copper in order to facilitate soldering to the ends of the winding. Finally, the end of the slice itself may be formed into a metal flap by electroplating or spraying with copper, and the wings of the sections need not then be cast from another metal. PL
