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.

The first sealing ring 4 is set to be L-shaped, the second sealing ring 5 is set to be C-shaped, one end of the first sealing ring 4 extends into the second sealing ring 5 to form an upper ring cavity and a lower ring cavity, sealing is carried out by arranging a sealing gasket 6 in the ring cavities, the preferable first sealing ring 4 comprises an L-shaped ring and a Z-shaped ring, the inner side of the L-shaped ring is fixedly attached to the outer ring 1, the contact area of the first sealing ring 4 and the outer ring 1 is increased, the strength and the stability of fixing are improved, the Z-shaped ring and the lower end of the L-shaped ring are fixed into an integrated structure, the Z-shaped ring is transported away from one end of the outer ring and inclines downwards, the upper end of the C-shaped second sealing ring 5 inclines upwards to form an inclined ring cavity matched with the Z-shaped ring, the sealing gasket 6 is arranged in the inclined ring cavity, the upper surface and the lower surface of the sealing gasket 6 are inclined surfaces and are respectively attached to the first sealing ring 4 and the second sealing ring 5, but the sealing gasket 6 and the outer side and the groove bottom of the second sealing ring 5 are arranged at intervals, when the upper and lower wearing sealing effect of the sealing washer 6 is reduced, the sealing washer 6 automatically slides towards the second sealing ring 5, the upper and lower surfaces of the sealing washer 6 are always attached to the first sealing ring 4 and the second sealing ring 5, and the service life is long.
