Abstract:
1. Centrifugal separator with a centrifuge frame, a rotatable, vertically-positioned, drive spindle with a drum mounted on it and a motor whose rotor axis is vertically positioned, whereby the spindle is mounted in a bearing pot so that it may rotate, and is suspended from a pivot (G; G′) with respect to the centrifuge frame so it is free to move in three dimensions; wherein the housing of the motor is securely attached to the centrifuge frame, such that the rotor axis of the motor substantially coincides with the longitudinal axis of the drive spindle at rest; wherein the rotor of the motor is connected at a coupling point (K) via flexible elastic coupling element to the spindle, and wherein the spindle is supported by at least two bearing points separated from each other by upper and lower bearings in the bearing pot; and wherein the bearing pot is connected with the centrifuge frame via elastic support elements; wherein the bearing pot with a bearing pot collar is supported by at least three elastic support elements on the centrifuge frame, and wherein at least three guide pins, arranged parallel to the longitudinal spindle axis, are attached to the bearing pot collar, each of which engages in a compatible hole in the centrifuge frame and are positioned so that they may be deformed along the axial direction and/or may be axially displaced into the holes.
