HYDRAULIC MACHINE HAVING A GEAR RING WHICH IS DIVIDED RADIALLY INTO AN INSIDE INNER PART HAVING THE FIRST INTERNAL TOOTHING AND AN OUTSIDE OUTER PART HAVING THE SECOND EXTERNAL TOOTHING, WHICH PARTS ARE ROTATABLE RELATIVE TO ONE ANOTHER

摘要

A hydraulic machine is disclosed, having a gearwheel (1) which has a first external toothing (8), a gear ring (3, 5), which has a first internal toothing (9) having at least one tooth more than and meshing with the first external toothing (8), and a second external toothing (10), and a toothed rim (6), which has a second internal toothing (11) having at least one tooth more than and meshing with the second external toothing (10). In such a machine it is desirable to have a greater freedom of design. For that purpose, the gear ring (3, 5) is divided radially into an inside inner part (3) having the first internal toothing (9) and an outside outer part (5) having the second external toothing (10), which parts are rotatable relative to one another.
