Abstract:
本发明涉及一种齿轮输送泵，所述齿轮输送泵包括驱动轴(28)、驱动齿轮(34)、被驱动齿轮(36)、在驱动轴(28)和驱动齿轮(34)之间的联接元件(32)以及壳体部分(31)，所述联接元件将所述驱动齿轮(34)与所述驱动轴(28)联接，所述壳体部分包括平行于所述齿轮(34，36)的壳体面(40a)，该壳体面形成至少用于所述联接元件(32)的推力轴承。根据本发明，所述壳体面(40a)形成在浇铸或压入在所述壳体部分(31)中的插入件(42)上。
Abstract(English):

The invention relates to a gear feed pump comprising a driving shaft (28), a driving toothed wheel (34), a driven toothed wheel (36), a coupling element (32) between the driving shaft (28) and the driving toothed wheel (34), which couples the driving toothed wheel (34) to the driving shaft (28), and a housing section (31) comprising a housing surface (40a) parallel to the toothed wheels (34, 36), which forms an axial bearing at least for the coupling element (32). According to the invention, the housing surface (40a) is formed on an insert (42) that is cast or pressed into the housing section (31).
