Title:
HYDRAULIC TOOTHED WHEEL MACHINE
Document Type and Number:
WIPO Patent Application WO/2010/102724
Kind Code:
A3
Abstract:
The invention relates to a toothed wheel machine comprising a housing (2) for receiving two meshing and especially helical-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) situated in the housing, and radially by a bearing shaft (8, 16) held in the bearing bodies. An axial component (47, 49) of a force resulting from the hydraulic and mechanical forces generated during the operation of the toothed wheel machine acts on each toothed wheel in the same axial direction. A counter-force is applied to at least one bearing shaft, a counter-force resulting from the counter-pressure acting against the axial force component.
