Abstract
PURPOSE: To provide a small and simple shaft sealing device by eliminating an oil tank for shaft sealing by installing a shaft sealing element to the intake side of a vane wheel so that high pressure is not applied on the outside of the shaft sealing element, thus preventing an outside liquid from penetrating to inside of an electric motor.
CONSTITUTION: A radial bearing metal 10 made of a sintered metal is attached to a through hole located on the center of a bottom end lid 9 which is integrated to the bottom end of a rotor 5. A stator shaft 4 passes the through hole. Number 11 is a mechanical seal used for sealing the clearence between the bearing metal 10 and the stator 4, and is located to the intake side of the vane wheel 19, therefore high pressure on the outside of the shaft sealing element 11 is avoided, thus preventing an outside liquid from penetrating to inside of an electric motor due to the pressure difference between the inside and the outside of the shaft sealing element, resulting elmination of an oil tank to be used for shaft sealing. Consequently, a shaft sealing device can be minimized and simplified.
