Abstract

The invention relates to a centrifugal separator (100) comprising a centrifugal frame (40), a rotatable vertically arranged spindle (10) provided with a drum (12), and a motor (90) having a vertical rotor axis (91). The spindle (10) is rotatably mounted in a bearing pot (20) and is mounted in a manner that permits it to three-dimensionally swing about a pivot (G) in relation to the centrifugal frame (40). According to the invention, the motor (90), via the housing thereof, is rigidly fixed to the centrifugal frame (40), whereby the rotor axis (91) of the motor (90) is aligned with the longitudinal axis (11) of the drive spindle (10) when at rest. The rotor of the motor (90) is connected to the spindle (10) at a coupling point (K) via a flexible coupling element (70). The spindle (10) is mounted in the bearing pot (20) at at least two interspaced bearing points (22, 24) by means of antifriction bearings. The bearing pot (20) is joined to the centrifugal frame (40) via elastic bearing elements (50).

Claims

1. Centrifugal separator (100; 100') with a centrifuge frame (40; 40'), a rotatable, vertically-positioned spindle (10) with a drum (12) mounted on it and a motor (90) whose rotor axis (91) is vertically positioned, whereby the spindle (10) is mounted in a bearing pot (20) so that it may rotate, and is suspended from a pivot (G; G') with respect to the centrifuge frame (40; 40') so it may oscillate through three dimensions, whereby .cndot. The housing of the motor (90) is securely attached to the centrifuge frame (40; 40'), whereby the rotor axis (91) of the motor (90) essentially coincides with longitudinal axis (11) of the drive spindle (10) at rest, .cndot. The rotor of the motor (90) is connected at a coupling point (K) via flexible elastic coupling element (70) to the spindle (10), and that the spindle (10) is supported by at least two bearing points (22, 24) separated from each other by roller bearings in the bearing pot (40; 40'), and .cndot. that the bearing pot (20) is connected with the centrifuge frame (40; 40') via elastic support elements (50) characterized in that the bearing pot (20) with a bearing pot collar (21) is supported by at least three elastic support elements (50) on the centrifuge frame (40; 40'), and that at least three guide pins (30; 30') parallel to the longitudinal axis are attached to the bearing pot collar, each of which engages in a compatible hole (44') in the centrifuge frame (40;
40') and that are positioned so that they may be deformed along the axial direction and/or may be axially displaced into the holes.

2. Centrifugal separator (100; 100') as in Claim 1, characterized in that the pivot point (G; G') is located in the area of the plane of symmetry of the lower bearing (24).

3. Centrifugal separator (100) as in Claim 1 or 2, characterized in that the separation of the coupling point (K) from the pivot point (G) is 0.1 to 0.25 times the distance from the pivot point (G) to the center of mass (S) of the rotating system consisting of drum (12) and spindle (10).

4. Centrifugal separator (100') as in Claim 1 or 2, characterized in that the coupling point (K) essentially coincides with the pivot point (G').

5. Centrifugal separator as in Claim 4, characterized in that each of the guide pins (30; 30') is installed into the hole (44') via a bushing (35').
