Abstract

Przedmiotem zgłoszenia jest pompa zębata o zazębieniu zewnętrznym, składająca się z korpusu, w którym wykonany jest otwór ssący, połączony poprzez komorę roboczą, w której pracują dwa koła zębate z otworem tłocznym, a pomiędzy zębami kół utworzona jest przestrzeń zasklepiona, charakteryzuje się tym, że wierzchołki zębów są ścięte w kierunku natarcia zęba na powierzchnię korpusu (1) tak, by powstała zbieżna szczelina smarna, przy czym ścięcie wierzchołka zęba tworzy profil o kształcie fragmentu spirali Archimedesa lub cylindryczny, o promieniu mniejszym niż promień wierzchołka zęba.The subject of the application is a gear pump with external toothing, consisting of a body in which a suction hole is made, connected through a working chamber in which two gear wheels with a pressure hole work, and a capped space is created between the wheel teeth, characterized by tooth tips are bevelled in the direction of tooth attack on the surface of the body (1) so as to create a converging lubrication gap, where the tooth tip chamfer creates a profile shaped like an Archimedes spiral fragment or cylindrical, with a radius smaller than the radius of the tooth tip.
