Abstract:
A self-contained apparatus for lubricating a roller bearing, comprised of1.1) a lubricating dispenser (1) which has a housing formed with a lubricant container with a supply of lubricant (2), a discharge device with an electric motor drive (3) and a control device (4) in the housing for the electric motor drive (3) and which is connected to the lubricating point of a roller bearing (7), and 1.2) a measuring device (8) associated with the roller bearing (7) for detecting the bearing condition and which is connected with the control device (4) of the lubricant dispenser (1), the housing being equipped with an indicating device for a signal indicating a bearing defect, the control device (4) of the lubricating dispenser (2) applying at intervals switching pulses to the electric motor drive (3) to output a small lubricant quantity and whereby the control device (4) changes the dispensing time points and/or the duration of the dispensing interval to automatically increase a lubrication feeding rate, the central device delivering a signal to the indicating device for signaling an incipient bearing defect or a lubricant condition deficiency when the measurement signal outputted by the measuring device (4) exceeds a predetermined value.
