Hydraulic toothed wheel machine

摘要

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.

1. A toothed wheel machine comprising:
a housing; a first bearing body accommodated in the housing and including a first axial surface; a second bearing body accommodated in the housing and including a second axial surface; a first bearing shaft accommodated in the bearing bodies; a second bearing shaft accommodated in the bearing bodies; a first toothed wheel accommodated in the housing, supported axially between the bearing bodies in a slidable manner by the first and second axial surfaces, and supported radially by the first bearing shaft, a second toothed wheel intermeshing with the first toothed wheel and being accommodated in the housing, the second toothed wheel being supported axially between the bearing bodies in a slidable manner by the first and second axial surfaces, and supported radially by the second bearing shaft, wherein a first axial force component of a force resulting from hydraulic and mechanical forces arising during operation of the toothed wheel machine acts on the first toothed wheel in a first axial direction against the first bearing body, and wherein the first toothed wheel and the first bearing body are configured such that a first counter-force acts on one of the first toothed wheel and the first bearing shaft in a direction opposite to the first axial force component and with a first magnitude that is less than that of the first axial force component such that the first toothed wheel is forced in the first axial direction against the first bearing body with a first resultant force that is smaller in magnitude than the first axial force component.
