Abstract

Disclosed is a centrifuge including a rotatable centrifugal drum and a drive spindle to drive the centrifugal drum. The drive spindle is rotatably mounted via a bearing in a housing supported elastically on a machine framework. Further included is a drive device including a drive motor to rotate the drive spindle and a lubricant system to lubricate the bearing. The lubricant system is configured to deliver lubricant from a lubricant supply tank through a lubricant channel into a region of the bearing. An injection device is arranged downstream of the lubricant-supply tank and is configured to deliver the lubricant into the region of the bearing by dispensing quantities of lubricant in temporally discrete pulses with a limited-time air stream. A method is disclosed of directing lubricant into a region of a bearing of the centrifuge as noted above.
