DEVICE FOR LUBRICATING A ROLLING BEARING

A device for lubricating a rolling bearing. The inventive device comprises a lubricant dispenser (1) connected to the lubricating point of the rolling bearing (7) and a measuring unit (8) allocated to the rolling bearing (7) for detecting the condition of the bearing. The lubricant dispenser (1) comprises a lubricant container with a supply of lubricant (2), a discharge device with an electromotor drive (3) and a control device (4) lined with the measuring device (8). The control device (4) of the lubricant dispenser (1) emits control signals to the electromotor drive (3) at certain intervals prompting it to discharge small amounts of lubricant and changes the discharge times and/or the duration of the discharge intervals if the measuring signal emitted by the measuring unit (8) exceeds a defined value. In this case, a signal for displaying an incipient bearing defect is also emitted.
