Abstract

Изобретение относитс  к машиностроению , в частности к шестеренным насосам, и может быть использовано в любой области машиностроени . Цель изобретени  - повышение надежности работы. Шестеренный насос содержит корпус 1 с днищем 2 и торцовой крышкой 3, в цилиндрических расточках 4 которого размещены ведуща  5 и ведома  6 шестерни и торцовые подп тники 7, выполненные за одно целое путем напылени  сло  металла, при этом на поверхности каждой цилиндрической расточки 4 со стороны днища 2 выполнена кольцева  выточка 8, а торцовый подп тник 7 снабжен кольцевыми выступами 9, сопр женными с кольцевыми выточками 8, 2 ил.The invention relates to mechanical engineering, in particular to gear pumps, and can be used in any field of mechanical engineering. The purpose of the invention is to increase the reliability of work. The gear pump comprises a housing 1 with a bottom 2 and an end cap 3, in cylindrical bores 4 of which a lead 5 and slave 6 gears and end baffles 7 are placed, integrally formed by spraying a metal layer, while the bottom 2 is provided with an annular recess 8, and the end bushing 7 is provided with annular protrusions 9 mating with annular recesses 8, 2, or ill.
