A lubricant dispenser comprising a housing, a lubricant supply container, a plunger, a telescopic hollow spindle, and an electromechanical servo-drive for changing the length of the telescopic hollow spindle. One end of the telescopic hollow spindle is fixed on the housing. With its other end, the telescopic hollow spindle cooperates with a plunger containing a passage opening for lubricant. The telescopic hollow spindle has a lubricant passage channel in which at least one check valve is arranged on the inlet side. The telescopic hollow spindle alternately carries out setting strokes of different lengths that increase or reduce the length of the spindle. The setting strokes are coordinated with each other so that with a setting stroke of the telescopic hollow spindle increasing the length of the spindle, a preset amount of lubricant displaced by the movement of the plunger enters the lubricant passage channel through the opening check valve.

Lubricant dispenser

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.

A self-aligning roller bearing includes an external ring with one curved external track, an internal ring with two curved internal tracks, two rows of rollers disposed between the external and internal rings, and a guide ring. The guide ring is located between the rows of rollers and is preferably configured as an circular annular disk. The guide ring has a rectangular cross section with the center line of the cross section running parallel to the bearing axis. The guide ring may also be dimensioned in such a way that the rollers are axially prestressed. The front faces of the rollers which face the guide ring are configured in a manner that the front faces only touch the guide ring at one point.
