Experimental Study on a High-speed spline-quill-shaft Coupling-rotor-bearing System

摘要

In this paper, a test rig contains a high-speed spline quill-shaft coupling used to connect a high-speed gearbox to a test rotor together. The rotor is supported by a pair of elastic ring combined ball bearings. The critical speeds of the system have been calculated. Experiments of this rotor system has been done. The system can operate stably and the maximum speed can reach more than 47000rpm.
