<p>1. A hydraulic generator-receiver for power transmission comprising two coupled gears within a stator which also has at least one inlet opening and one return opening for a liquid under pressure, while two flanges enclose the stator on either side of two gears against which they form a lateral seal and diametrical channels are provided within the gears, characterised in that the stator comprises a flexible envelope (39) subjected externally to a centripetal pressure which enables it to make a seal against the tips of the teeth of the helical gears (9, 10) which are floatingly mounted within the envelope between two flexible flanges (21, 22) with hydrostatic compensation providing a seal between these flanges and the faces of the gears, internal hydraulic balancing being effected by means of a "hydraulic winding" comprising rotor conduits (19) within the gears (9 and 10) and stator conduits (23) within the flanges (21 and 22), successive commutations between the rotor conduits (19) and stator conduits (23) being effected by the passages of their ends one before the other in a circle of commutation (20) and simultaneously at the tooth spaces within the pitch circle at the other end of the stator conduits (23) to provide a permanent link between opposing tooth spaces when the number of teeth is even and opposing tooth spaces with an offset of a half step when the number of teeth is odd, except in zones (6 and 3), zones (6) where hydraulic bearings are created diametrically opposite the meshing point (3) of the gears (9 and 10) so that as the gears (9 and 10) rotate the said winding places opposing pairs of teeth into a relationship so that the same hydraulic pressure is obtained in the tooth spaces for diametrically opposite angular positions and so that reverse forces are applied to the gears so as to ensure that they mesh without play.</p> |
