Abstract

PURPOSE: A method of simply and reliably contrqlling thrust by extending bearing supporting fittings lengthways and facing them toward the edge surface of a rotor, where the thrust load is regulated by the clearance.
CONSTITUTION: A bearing supporting fitting 17 is extended and made longer than usual and a collar 11 is eliminated by providing a clearance equivalent to thrust size S between the bearing supporting fitting 17 and the edge face of a rotor 3. Some theoretical problems still remain for such a structure because the rotor 3 is disposed on a movable side and the bearing supporting fitting 17 is disposed on the unmovable side. However, if it is possible to satisfy such conditions that the parts should never be connected during normal operation and the thrust size is enough to be able to control only during abnormal conditions, for superiorer performance than the existing one's can be attained.
