<p>A combination of two interconnected shafts for high-speed rotors This patent presents the invention of a shaft joint with an Inverse Conical Stopper. The joint is a combination of interconnected shafts. The joint is between two shafts. In the joint, one shaft is inserted into the other. The interface between the two shafts can be of any type: press-fit, thermally shrank, threaded, etc. The Inverse Conical Stopper: - Prevents swelling of the joint; - Enforces concentric alignment of the two shafts; and - Pre-stresses the interface. Besides, the shaft-to-shaft interface can be also either bonded or non-bonded. In the former case, the Inverse Conical Stopper also prevents failure of the bond by: Reducing loads on the bond by using the pre-stress to (partly) compensate for the centrifugal load. The Inverse Conical Stopper makes the joint particularly suitable for high centrifugal loads and high rotation speeds.</p> |
