| 20110103993 | GEAR WHEEL WITH PROFILE CAPABLE OF MESHING WITH SEMI-ENCAPSULATION IN A GEARED HYDRAULIC APPARATUS - A geared hydraulic apparatus comprises a pair of gear wheels which mesh with each other with semi-encapsulation. Each gear wheel has a plurality of teeth with a profile which falls within a band of tolerance of ±15, more preferably ±20, and even more preferably ±30 with respect to the height of the tooth, with respect to a profile similar to a profile defined by a predetermined spline function passing through a plurality of nodal points having pre-established coordinates {X,Y} with origin on the rotational axis. | 05-05-2011 |
