Abstract

Przedmiotem wynalazku jest zatrzask zabezpieczajacy elementy obrotowe przed wypadnieciem z uchwytu, zwlaszcza noze organu urabiajacego kombajnu górniczego. Zatrzask jest uksztaltowany z materialu o jednolitym przekroju, o dwóch koncach nie stykajacych sie ze soba, w ten sposób, ze utworzone wystepy oraz wneki lacza sie ze soba i tworza otwarta figure, symetryczna wzgledem osi pionowej, przy czym wystepy wystaja poza srednice chwytu noza. Zatrzask (1), po zamontowaniu, obejmuje dno rowka (11) chwytu (12) noza (14) zarówno swoja wewnetrzna jak i zewnetrzna powierzchnia. Konce ( 2 i 2') skierowane do wewnatrz figury zatrzasku (1), przechodza w slizgi (3 i 3') wyjsciowe, które poprzez zagiecia (4 i 4') przechodza w slizgi (5 i 5') wejsciowe. Slizgi (5 i 5') wejsciowe, poprzez wystepy (6 i 6') dolne, przechodza w ramiona (7 i 7') laczace sie poprzez boczne wystepy (8 i 8') i wneki (9 i 9') z górnym wystepem (10). Odleglosc (d) grzbietów zagiec (4 i 4') oraz odleglosc (e) grzbietów wnek (9 i 9') jest mniejsza od srednicy dna rowka (11) chwytu (12) noza.
