ABSTRACT:
A device for feeding grease to the bearings of a rotary machine comprising a stator and a rotor, the device comprising injectors for injecting grease into said bearings, the injectors being controlled by an electronic control circuit which has inputs receiving signals from sensors for sensing parameters characteristic of the operating state of the bearings. The injectors are connected to a supply of grease under pressure and comprise injector blocks each connected to a respective bearing feeder channel. The sensors are pressure and temperature sensors, and the electronic circuit includes a clock and generates injection cycles as a function of a preestablished program, taking account of the information provided by the sensors and by the operating time of the bearings.
