Oil sealing apparatus of high power in-wheel motor

摘要

An oil sealing device for a high-power in-wheel motor is disclosed. To this end, the oil sealing device of the present invention includes a ring-shaped first support frame that is closely fixed to the inner circumferential edge of the outer rotor, a first buffer member formed on the first support frame with a vulcanization mold, and the end of the outer circumferential surface of the stator. An opening between the first surface to be closely fixed, the second surface vertically extending from the first surface to the inside of the in-wheel motor, the third surface vertically extending from the second surface and formed horizontally with the first surface, and the third surface A ring-shaped second support frame having a fourth surface vertically extending from the first surface to the outside of the in-wheel motor so that a vulcanization mold is formed on the third surface of the second support frame, and the end is the first support. And a second buffer member having at least one or more lip formed in elastic contact with the frame. Accordingly, it is possible to prevent foreign substances from entering from the outside of the in-wheel motor.
