Novel oil separation device for wind power gear box

The invention relates to a novel oil separation device for a wind power gear box. The novel oil separation device comprises a box, an oil separation ring baffle, an upper oil separation ring, a metal lamination sealing ring, a lower oil separation ring and a planetary frame, the oil separation ring baffle and the upper oil separation ring are fixed on the box through bolts, the lower oil separation ring is fixed on the planetary frame through bolts, the metal lamination sealing ring is mounted in a sealing groove of the metal lamination sealing ring and contacts with the upper oil separation ring, the upper oil separation ring does not directly contact with the lower oil separation ring, and inner cavities of the box, the upper oil separation ring and the lower oil separation ring are communicated to form an oil channel. The novel oil separation device has the advantages of good sealing performance and abrasion resistance, easiness in manufacturing, low manufacturing lost and long in service life. 本发明涉及种风电齿轮箱
