Abstract
A swinging bucket centrifuge rotor having free-floating trunnion pins with each pair of trunnion pins having an interlocking mechanism disposed therebetween. The rotor includes a yoke having an axis of rotation, a plurality of spaced arms extending radially outward from the axis of rotation, each of which terminates in a bulwark. The bulwark includes a pair of intersecting bores, each of which extends along an axis lying in a plane spreading transverse to the axis of rotation. Each of the trunnion pins has a lengthwise axis and is disposed in one of the pair of intersecting bores. The trunnion pins include trunnion and coupling portions. The coupling portion has a surface. The interlocking mechanism includes a recess formed into the surface of the coupling portion and a coupling pin. The recess of each of trunnion pin of the pair of trunnion pins is superimposed upon the recess of the remaining trunnion pin, forming a chamber. The coupling pin is disposed within the chamber and is adapted to rest within the recess of each of the pair of trunnion pins, thereby preventing translational motion of each of said pair of trunnion pins in a direction perpendicular to the axis of rotation.
