Date Dec. 17, 1987.A screw joint between two components, such as the rotor (3) and a lid locking ring (5) of an ultracentrifuge. During rotation the forces transferred by the screw joint and/or the centrifugal forces acting on the components tend to give rise to uneven distribution of the load between the threads of the screw joint. For distributing the forces transferred by the screw joint more uniformly, one of the components (3, 5) includes, a part (7) intended to be deformed due to the rapid rotation of the component to strive to rotate the component about axes perpendicular to axial sections through the center axis of the screw joint. In this way, variable contributions to the radial deformation of this component are produced along the axial extension of the screw joint, so that the load distribution is equalized between the screw threads. |
