A device for lubricating a rolling bearing. The inventive device comprises a lubricant dispenser ( ) connected to the lubricating point of the rolling bearing ( ) and a measuring unit ( ) allocated to the rolling bearing ( ) for detecting the condition of the bearing. The lubricant dispenser ( ) comprises a lubricant container with a supply of lubricant ( ), a discharge device with an electromotor drive ( ) and a control device ( ) lined with the measuring device ( ). The control device ( ) of the lubricant dispenser ( ) emits control signals to the electromotor drive ( ) 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 ( ) exceeds a defined value. In this case, a signal for displaying an incipient bearing defect is also emitted.

Device for lubricating a rolling bearing

An automatic lubricant dispenser has a lower housing part formed with an outlet, a piston displaceable along an axis in the lower part and forming therein a compartment, a spindle extending along the axis, threaded into the piston, having an upper end above the piston provided with a lower coupling half, and a body of fluent lubricant filling the compartment. An upper housing part removably securable to the lower part holds an electrical motor unit having an output shaft projecting downward at the axis and provided with an upper coupling half axially engageable with the lower coupling half. The coupling halves are axially engageable to rotationally couple the motor output shaft to the spindle so that electrical energization of the motor when the coupling halves are engaged displaces the piston and expresses lubricant from the outlet. A sensor connected to the shaft generates an output after a predetermined angular displacement of the shaft. An erasable nonvolatile memory in the upper housing part is associated with a reset switch for clearing the nonvolatile memory and with electrically powered controller. This controller is also connected to the sensor means and nonvolatile memory for periodically energizing the motor, for storing in the nonvolatile memory information about elapsed time since last energization of the motor and the number of outputs emitted by the sensor means, and for reading the information stored in the memory.
