HYDRAULIC TOOTHED WHEEL MACHINE

摘要

The invention relates to a toothed wheel machine comprising a housing (2) for receiving two meshing toothed wheels (10, 12). Said toothed wheels are axially mounted in a sliding manner by axial surfaces (30, 32, 34, 36) between bearing bodies (26, 28) received in the housing, and radially by a bearing shaft (8, 16) received in the bearing bodies. Hydraulic and mechanical forces are generated during the operation of the toothed wheel machine, an axial force component of said forces acting on each toothed wheel in the same axial direction. In order to counteract said axial force component, a pressure field is provided between at least one axial surface of one of the toothed wheels in the direction of action of the axial force component, and the bearing body adjacent to the at least one axial surface.
