Abstract

Účelom riešenia je zabezpečit vysokú tvrdost a pevnosť kovografitového materiálu s leštiacou schopnosťou filmu. Uvedeného účelu sa dosiahne zabezpečením kryštalickej štruktúry kovografitu kombináciou východzích surovin a technologického postupu. Kovografit s leštiacou schopnosťou filmu sa može využívať v elektrotechnickom a strojárskom priemysleThe purpose of the solution is to ensure high hardness and strength of the kovo-graphite material with film polishing ability. The stated purpose is achieved by ensuring the crystalline structure of kovo-graphite by a combination of starting materials and technological process. kovo-graphite with film polishing ability can be used in the electrical and mechanical engineering industries

Description

Vynález sa týká kovografitového materiálu s leštíacou schopnosťou filmu na 12 V spúšťačoch.BACKGROUND OF THE INVENTION The present invention relates to a metallographic material having a film polishing capability of 12V starters.

Doteraz používaný kovografitový materiál pre 12 V spušťače obsahuje velké množstvo médi a malý obsah grafitu. Použitý grafit je vločkový s nízkým obsahom popola. Obsah popola je menší ako 6—7 %. Nevýhodou doteraz používaného materiálu je malá tvrdost a pevnosť vzhladom na použitie velkého množstva kovu a vločkových krystalických zřn prírodného grafitu.The metal-graphite material used so far for 12 V starters contains a large amount of media and low graphite content. The graphite used is a flake with a low ash content. The ash content is less than 6-7%. A disadvantage of the material used so far is the low hardness and strength due to the use of large amounts of metal and flake crystalline grains of natural graphite.

Uvedené nedostatky odstraňuje kovografitový materiál s leštiacou schopnosťou filmu na 12 V spúšťačoch podlá vynálezu, ktorého podstatou je, Že materiál pozostáva z 55 až 70 °/o médi, 6—12 % olova, 0,5—3 °/o koksovacieho zvyšku a obsahuje 15—38,5 % grafitu s obsahom popola nad 10 % s malými krystalickými zrnami, kde 80 °/o krystalických častíc je menších ako 100 mikrometrov. Vynález zabezpečuje vysakú tvrdost a pevnosť materiálu. Krystalická konfigurácia jednotlivých komponentov a zvolený obsah popola v grafite zaisťujú tvorbu filmu na komutátore startéra a jeho hladký povrch. Kovografitový materiál aj pri menšom obsahu kovu zabezpečuje přenos elektrického prúdu z kief do komutátora a výkon spúšťača.The above-mentioned drawbacks are eliminated by a metallographic material having a film-polishing capability of the 12-volt starters of the invention, which consists in that the material consists of 55-70% of the medium, 6-12% lead, 0.5-3% of the coke residue and contains 15-38.5% graphite with an ash content above 10% with small crystalline grains, where 80% of the crystalline particles are less than 100 microns. The invention ensures high hardness and strength of the material. The crystalline configuration of the individual components and the selected ash content in the graphite ensure film formation on the starter commutator and its smooth surface. Even with a lower metal content, the metallographic material ensures the transfer of electrical current from the brushes to the commutator and the starter output.

Kovografitový materiál s leštiacou schopnosťou filmu na 12 V spúšťačoch možno využiť v elektrotechnickom priemysle.Metallographic material with film polishing capability on 12 V starters can be used in the electrical industry.
