Abstract
A toothed wheel machine including a housing for receiving two meshing and especially helical-toothed wheels. The toothed wheels are axially mounted in a sliding manner by axial surfaces between bearing bodies received in the housing, and radially by a bearing shaft received in the bearing bodies. During the operation of the toothed wheel machine, an axial component of a force resulting from the hydraulic and mechanical forces generated during operation acts on each toothed wheel in the same axial direction. A counter-force against the respective axial force component is applied to the toothed wheels and/or bearing shafts, each counter-force applying the same amount of pressure as the respective axial force component, or less than same.
