The first sealing ring and the second sealing ring are both L-shaped, the first sealing ring and the second sealing ring are arranged in a crossed mode to form a square shape, and the sealing washer is arranged in a ring cavity between the first sealing ring and the second sealing ring.
The first sealing ring is L-shaped, the opening of the first sealing ring is downward, one side of the first sealing ring is fixed on the outer ring, the other side of the first sealing ring faces the inner ring and is obliquely and downwardly arranged, the second sealing ring is C-shaped, the opening of the second sealing ring faces the outer ring, the inner wall of the second sealing ring is fixed with the periphery of the inner ring, the other side of the first sealing ring extends into the opening of the second sealing ring, and the sealing washer is arranged between the first sealing ring and the second sealing ring.
And a plurality of ring grooves are formed in the inner wall and/or the periphery of the sealing washer.
The ball is provided with double row and the ball is radial ball, and the ball outside sets up towards inboard slope.
The beneficial effects of the utility model are that, a compound canned type stainless steel bearing is provided, seal between bearing outer loop, the inner ring through the mode that sets up first sealing ring, second sealing ring and seal ring, prevent effectively that dust, grit and so on dregs will enter into the bearing in, seal structure directly sets up on the bearing, need not to rely on the axle bed.
Drawings
Fig. 1 is a schematic sectional structure of the present invention.
In the drawing, the sealing ring comprises a ring 1, an outer ring 2, an inner ring 3, a ball 4, a first sealing ring 5, a second sealing ring 6 and a sealing gasket.
Detailed Description
As shown in fig. 1, the utility model provides a compound canned type stainless steel bearing, including outer loop 1, inner ring 2 and the ball 3 of setting between outer loop 1, inner ring 2, be provided with seal structure on the outer loop 1, seal structure includes first sealing ring 4, second sealing ring 5 and sets up seal ring 6 between first sealing ring 4, second sealing ring 5, on first sealing ring 4 one side was fixed in outer loop 1, second sealing ring 5 was fixed in the inner ring 2 periphery in the outer loop 1 outside, formed seal structure with the help of seal ring 6 between first sealing ring 4, the second sealing ring 5.
Increase seal structure between outer loop 1 and inner ring 2, first sealing ring 4 is fixed in outer loop 1 side, and second sealing ring 5 is fixed on the inner ring, forms the ring chamber between first sealing ring 4 and the second sealing ring 5, increases seal ring 6 in the ring chamber, realizes sealed between outer loop 1 and the inner ring 2, further prevents that the dust from getting into by the clearance between outer loop 1 and the inner ring 2, improves sealed effect, increases the life of bearing.
As shown in fig. 1, the first sealing ring 4 and the second sealing ring 5 are both L-shaped, the first sealing ring 4 and the second sealing ring 5 are arranged in a crossed manner to form a square shape, and the sealing washer 6 is arranged in an annular cavity between the first sealing ring 4 and the second sealing ring 5.
A closed ring cavity is formed between the first sealing ring 4 and the second sealing ring 5, and a sealing gasket 6 is additionally arranged in the ring cavity, so that the sealing effect is further improved.
As shown in fig. 1, the first sealing ring 4 is L-shaped and has a downward opening, one side of the first sealing ring 4 is fixed on the outer ring 1, the other side of the first sealing ring is toward the inner ring 2 and is obliquely and downwardly disposed, the second sealing ring 5 is C-shaped and has an opening toward the outer ring 1, the inner wall of the second sealing ring 5 is fixed to the periphery of the inner ring 2, the other side of the first sealing ring 4 extends into the opening of the second sealing ring 5, and the sealing gasket 6 is disposed between the first sealing ring 4 and the second sealing ring 5.
