MACHINE BEARING LUBRICATION DEVICE

Lubricant supply device for bearings (4, 5) of a rotating machine (1) comprising a stator (2) and a rotor (3), comprising means (12, 10, 11) for injection of lubricant into the said bearings, the said means being controlled by an electronic control circuit (17) receiving, at its input, signals from sensors (18 to 21) of parameters which are characteristic of the operating state of the bearings, characterised in that the said means comprise a reservoir (12) for lubricant under pressure linked to injector blocks (10, 11) each connected to a feed channel (6, 7) of a bearing, the said sensors being pressure and temperature sensors, and the said electronic circuit (17) comprising a clock and deriving, as a function of a pre-established programme, the injection cycles, taking account of the data supplied by the said sensors and of the operating time of the bearings. ……
