Abstract:
1. A swing rotor for a centrifugal separator, the swing rotor comprising: a hub configured to be connected to a drive shaft; and a rotor body disposed around the hub, wherein a plurality of pairs of arms are disposed at the rotor body such that arms of each pair face each other, wherein a holding pin configured to hold a bucket such that the bucket is capable of swinging is disposed to the arm such that the holding pin extends toward an arm facing the arm to which the holding pin is disposed, wherein an engagement portion which is configured to be supported by the holding pin is formed to the bucket, and wherein a sliding surface of the holding pin with an engagement portion of the bucket is formed such that a width of a contact area, which is an area that the holding pin contacts with the engagement portion of the bucket, in an axial direction of the holding pin when the bucket does not swing differs from a width of the contact area in the axial direction when the bucket reaches a horizontal position by swinging during a centrifugal separation operation.
