ABSTRACT:
In a swinging type rotor of a centrifugal machine of the type wherein the rotor is provided with a plurality of equally spaced radial arms and each arm is provided with a pair of trunnion pins for hanging buckets, a through opening extending in a direction perpendicular to a longitudinal axis of each arm is formed near an outer end thereof. A pair of hollow trunnion pins are inserted into opposite ends of the through openings. The hollow trunnion pins are provided with oppositely directed screw threads mating with a threaded pin. Outer portions of the trunnion pins are inclined toward the arm. Directions of the screw threads of the trunnion pins and of the threaded pin are selected such that when the buckets are swung about the trunnion pins under centrifugal force threading of the trunnion pins are tightened.
