Abstract

A procedure is described for the balancing of rotors without journals, as well as an auxiliary bearing arrangement used to accomplish the balancing of such rotors. Fluids function to separate the rotor being balanced from the journal exterior of the bearing arrangement and also to separate the rotor from the support surface of the bearing arrangement. A high level of precision is achieved while avoiding fixed or expanding mandrels. Improvement of the automated operation of balancing machines of this type is possible without wear on the machine. Also, additional disturbance frequencies are avoided.
